1 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Implemented CONNECT and SHUTDOWN commands in the client.
5 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7 * DIE command was renamed to SHUTDOWN. Updated the both code
10 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
11 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
13 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
16 * Added function silc_server_create_connection function to create
17 connection to remote router. My server implementation actually
18 does not allow router to connect to normal server (it expects
19 that normal server always initiates the connection to the router)
20 so the CONNECT command is only good for connecting to another
23 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
26 or some other client was kicked from the channel.
28 Implemented the handling of the notify type to both client
31 Implemented silc_server_send_notify_kicked to send the KICKED
32 notify. It is used to send it to the server's primary router.
34 * Implemented the KICK command into server and client.
36 * Added `query' argument to the silc_idlist_get_client function
37 to indicate whether to query the client from server or not if
40 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
41 to indicate that the client is not channel founder.
45 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
47 * Removed the rng context from SilcPacketContext structure and
48 changed that the packet routine uses the Global RNG API.
50 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * Added support for quit message that client can "leave" on the
53 channel when it quits the SILC. It is ditributed inside the
54 SILC_NOTIFY_TYPE_SIGNOFF notify type.
56 Added silc_server_free_client_data that will take the
57 signoff message as argument.
59 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
61 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
63 * Updated parts of the protocol specification to keep it up
66 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
69 payloads in one packet.
71 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
72 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
73 use now the new List flag.
75 * Also deprecated the following packet types: REPLACE_ID,
76 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
78 * Added list support for Notify packet in server.
80 * Added silc_server_send_notify_channel_change to send the
81 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
82 the silc_server_send_replace_id.
84 * Added silc_server_send_notify_nick_change to send the
85 NICK_CHANGE notify type. Deprecates the function
86 silc_server_send_replace_id.
88 * Added silc_server_send_notify_join to send the JOIN notify type.
89 Deprecates the function silc_server_send_new_channel_user.
91 * Added silc_server_send_notify_leave to send LEAVE notify type.
92 Deprecates the function silc_server_send_remove_channel_user.
94 * Added silc_server_send_notify_cmode and
95 silc_server_send_notify_cumode to send CMODE and CUMODE notify
96 types. Deprecates the silc_server_send_set_mode function.
98 * Added SERVER_SIGNOFF notify type to indicate that server has
99 quit. This means that all clients on the channel from that
100 server will drop. This can be also used when netsplit happens.
102 Deprecated REMOVE_ID packet type since it is not needed anymore
105 Added silc_server_send_notify_server_signoff to send the
106 SERVER_SIGNOFF notify type. Deprecates the function
107 silc_server_send_remove_id.
109 Added also silc_server_send_notify_signoff to send the
112 * Employed the PKCS #1. It is the mandatory way to do RSA in the
113 SILC protocol from this day on. Changed the protocol
114 specification as well.
116 * Added silc_server_send_notify_topic_set to send TOPIC_SET
117 notify type. It is used between routers to notify about
118 topic changes on a channel.
120 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
123 * Partly updated the protocol specification to comply with the
124 changes now made. It is still though a bit outdated.
126 * The JOIN notify type now takes one extra argument <Channel ID>.
127 The packet used to be destined to the channel but now the
128 JOIN type may be sent as list thus it is impossible to
129 destine it to any specific channel. By adding this argument
130 it is again possible.
132 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
134 * Added CREDITS file. The CHANGES and CREDITS file will appear
135 in the distribution as well.
137 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
140 types in the server's silcd/packet_receive.c.
142 * Implemented CMODE and CUMODE to work in router environment.
144 * Fixed minor encoding and decoding buglet from the
145 lib/silccore/silcmode.c.
147 * Fixed buffer overflow from lib/silcclient/command.c in USERS
150 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
152 * Changed all SilcConfigServer* and silc_config_server* to
153 SilcServerConfig* and silc_server_config*, respectively.
156 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Associated the ID (client or server ID) to the Authentication
159 Payload to avoid any possibility of forging. Updated the
160 protocol specification and the code accordingly.
162 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * The RSA key length is now save to the RsaKey context in the
165 key generation process in lib/silccrypt/rsa.c. The key length
166 is now used to figure out the maximum size of the block allowed
167 to be encrypted/signed.
169 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
170 is equivalent to the silc_mp_mp2bin but does not allocate any
173 * Changed silc_mp_mp2bin API to take length argument. If it is
174 non-zero then the buffer is allocated that large. If zero, then
175 the size is approximated using silc_mp_sizeinbase, which however
178 * Created Global RNG API which is global RNG that application can
179 initialize. After initializing, any routine anywhere in the
180 code (including library) can use RNG without allocating a new
181 RNG object. This was done to allow this sort of use of the
182 RNG in code that has no chance to allocate RNG object. All
183 applications currently allocate this and many routines in the
184 library use this. Affected file lib/silccrypt/silcrng.[ch].
186 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
187 it to use the Global RNG API.
189 * Defined Authentication Payload into protocol specification that
190 is used during SILC session to authenticate entities. It is
191 used for example by client to authenticate itself to the server
192 to obtain server operator privileges.
194 Implemented this payload into the lib/silccore/silcauth.[ch].
195 Implemented also routines for public key based authentication
196 as the new protocol specification dictates.
198 Moved definitions of different authentication methods from
199 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
201 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
202 silc_pkcs_verify and silc_pkcs_sign_with_hash and
203 silc_pkcs_verify_with_hash functions into the file
204 lib/silccrypt/silcpkcs.[ch].
206 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * The client entry's userinfo pointer must be always valid.
209 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
210 will fail since it requires the userinfo. Now, the userinfo
211 is allocated as "" if actual userinfo does not exist. Actually,
212 it must exist and it is totally Ok to drop client connections
213 that does not announce the userinfo. However, we will make
214 this workaround for now.
216 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
217 to return the remote port by socket.
219 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
221 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
222 SILC_SERVER_PENDING_EXEC and added an new macro
223 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
224 data or when error occurs while processing the pending command.
226 Added new argument `destructor' into silc_server_command_pending
227 and to the SilcServerCommandPending object. This destructor is
228 now called after calling the pending callback or if error occurs
229 immediately. If error occurs the actual pending callback won't
230 be called at all - only the destructor. The destructor may be
231 NULL if destructor is not needed.
233 All this applies for client library code as well. Similar
234 changes were made there as well for the pending commands.
236 In the client, the application must now allocate the
237 SilcClientCommandContext with the silc_client_command_alloc
240 * Added reference counter to the SilcServerCommandContext. Added
241 function silc_server_command_alloc and silc_server_command_dup
244 Same type of functions added to the client library for the same
247 * Removed the cmd_ident from IDListData away since it is now
248 global for all connections. It is the command identifier used
249 in command sending and with pending commands. The affected file
252 * Added reference counter to the SilcSocketConnection objecet to
253 indicate the usage count of the object. The object won't be
254 freed untill the reference counter hits zero. Currently only
255 server uses this, and client ignores it. The client must be
256 set to use this too later. The affected files are
257 lib/silccore/silcsockconn.[ch]. Added also the function
258 silc_socket_dup to increase the reference counter.
260 This was mainly added because it is possible that the socket
261 is removed underneath of pending command or other async
262 operation. Now it won't be free'd and proper DISCONNECTING
263 flags, etc. can be set to avoid sending data to connection that
264 is not valid anymore.
266 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
267 the connection. After that it sets SILC_SET_DISCONNECTED.
268 It is, however, possible that the socket data is not still freed.
269 The silc_server_packet_process now checks that data is not
270 read or written to connection that is DISCONNECTED. The socket
271 get's freed when the reference counter hits zero.
273 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
275 * Changed the client operation API: channel_message operation's
276 `sender' is now the client entry of the sender, not the nickname
277 and the `channel' is the channel entry, not the channel name.
279 In the private_message operation the `sender' is now also the
280 client entry of the sender not the nickname.
282 Affected file is lib/silcclient/ops.h and all applications
283 using the client operations.
285 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
287 * Moved the calling of ops->connect() from connect_to_server_final
288 into receive_new_id functin since that is the point when the
289 client is actually allowed to send traffic to network. The
290 affected file is lib/silcclient/client.c.
292 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
295 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
296 (if needs broadcasting) instead of broadcasting the packets one
297 by one which would make a burst in the network traffic.
299 * Added `broadcast' argument to the functions in silcd/server.[ch]
300 silc_server_create_new_channel[_with_id] to indicate whether
301 to send New Channel packet to primary router.
303 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Added new function into the silcd/server.[ch] files:
306 silc_server_create_new_channel_with_id to create new channel with
307 already existing Channel ID.
309 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
310 lib/silccore/silcpacket.h. This packet is used t send list of
311 Set Mode payloads inside one packet. Server uses this to set
312 the modes for the channels and clients on those channels, that it
313 announced to the router when it connected to it. The protocol
314 specification has been updated accordingly.
316 * The silc_server_new_channel did not handle the packet coming
317 from normal server as it normally does not send that. However,
318 when it announces its channels it does send it. Implemented
319 the support for that.
321 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
322 into the file lib/silccore/id.h.
324 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Fixed memory leaks in the functions silc_idlist_del_client,
327 silc_idlist_del_channel and silc_idlist_del_server in the file
328 silcd/idlist.c. All of those leaked like a sieve.
330 * Fixed some small memory leaks in the client's function
331 silc_client_notify_by_server.
333 * Added functions into silcd/server.c: silc_server_announce_clients,
334 silc_server_announce_channels and silc_server_announce_server.
335 These functions are used by normal and router server to announce
336 to its primary router about clients, channels and servers (when
337 router) that we own. This is done after we've connected to the
340 These functions effectively implements the following packet types:
341 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
342 and SILC_PACKET_NEW_ID_LIST.
344 * Added new functions into the silcd/packet_receive.[ch]:
345 silc_server_new_id_list, silc_server_new_channel_list and
346 silc_server_new_channel_user_list to handle the incoming
347 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
349 * Added support of changing Channel ID in the function
350 silc_server_replace_id. If the server that announces a channel
351 to the router already exists in the router (with same name but
352 with different Channel ID), router is responsible to send
353 Replace ID packet to the server and force the server to change
354 the Channel ID to the one router has.
356 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
357 client that the Channel ID has been changed by the router. The
358 normal server sends this to the client. Client must start using
359 the new Channel ID as the channel's ID.
361 Implemented handling of this new type into lib/silcclient/client.c
362 into the function silc_client_notify_by_server.
364 * Added new function silc_idlist_replace_channel_id into the files
365 silcd/idlist.[ch] to replace the Channel ID.
367 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Call silc_server_command_identify_check always when processing
370 the IDENTIFY command in silcd/command.c
372 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
374 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
375 send keepalive packets. The packet can be sent by clients,
378 Added function silc_socket_set_heartbeat into the file
379 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
380 If not set, the heartbeat is not performed. The actual
381 heartbeat is implemented in the low level socket connection
382 library. However, application is responsible of actually
385 Added silc_server_send_heartbeat to send the actual heartbeat
386 packet into silcd/packet_send.[ch]. Server now performs
387 keepalive with all connections.
389 * Added silc_task_get_first function into lib/silcutil/silctask.c
390 to return the timeout task with shortest timeout. There was a bug
391 in task unregistration that caused problems. TODO has been
392 updated to include that task system must be rewritten.
394 * The client library will now resolve the client information when
395 receiving JOIN notify from server for client that we know but
396 have incomplete information.
398 * Rewrote parts of silc_server_remove_from_channels and
399 silc_server_remove_from_one_channel as they did not remove the
400 channel in some circumstances even though they should've.
402 * Encryption problem encountered in server:
404 The LEAVE command used to send the Channel Key packet to the
405 router immediately after generating it. However, the code
406 had earlier sent Remove Channel user packet but not immediately,
407 ie. it was put to queue. The order of packets in the router
408 was that Channel Key packet was first and Remove Channel User
409 packet was second, even though they were encrypted in the
410 reverse order. For this reason, MAC check failed. Now, this
411 is fixed by not sending the Channel Key packet immediately but
412 putting it to queue. However, this is more fundamental problem:
413 packets that are in queue should actually not be encrypted
414 because packets that are sent immediately gets encrypted
415 actually with wrong IV (and thus MAC check fails). So, packets
416 that are in queue should be encrypted when they are sent to
417 the wire and not when they put to the queue.
419 However, the problem is that the current system has not been
420 designed to work that way. Instead, the packet is encrypted
421 as soon as possible and left to the queue. The queue is then
422 just purged into wire. There won't be any fixes for this
423 any time soon. So, the current semantic for packet sending
426 o If you send packet to remote host and do not force the send
427 (the packet will be in queue) then all subsequent packets to the
428 same remote host must also be put to the queue. Only after the
429 queue has been purged is it safe again to force the packet
432 o If you send all packets immediately then it safe to send
433 any of subsequent packets through the queue, however, after
434 the first packet is put to queue then any subsequent packets
435 must also be put to the queue.
437 Follow these rules and everything works fine.
439 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Added new function silc_server_remove_clients_by_server to
442 remove all client entries from ID list when the server connection
443 is lost. In this case it is also important to invalidate all
444 client entires as they hold the invalid server entry. This
445 fixes fatal bug when server has lost connection and will reconnect
448 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Made some sanity checks to silc_server_daemonise like to check
451 whether the requested user and group actually exists.
453 * Added sanity check to SKE's silc_ske_responder_finish to check
454 that the public and private key actually is valid.
456 * Invalidate the client's nickname when receiving Replace ID
457 packet and the Client ID is being replaced. This means that the
458 server will query the nickname if someone needs it (client)
461 * Sort the ID Cache in client library when the ID Cache data
462 has changed (needs sorting).
464 * Do not allow for SILC client to create several connections to
465 several servers. The client does not support windows right now
466 and generating multiple connections causes weird behaviour.
468 Irssi-silc client does support windows and can handle several
469 connections without problems, see: www.irssi.org and SILC plugin.
471 * Fixed some places where client was added to the IDList. The
472 rule of thumb is following (in order to get everything right):
473 If the client is directly connected local client then the
474 `connection' argument must be set and `router' argument must be
475 NULL to silc_idlist_add_client function. If the client is not
476 directly connected client then the `router' argument must
477 bet set and the `connection' argument must be NULL to the
478 silc_idlist_add_client function.
480 * The funtion silc_server_packet_send_local_channel actually did
481 not check whether the client was locally connected or not. It
482 does that now. Fixed a bug related to LEAVE command.
484 * Fixed Remove Channel User payload parsing bug in server's
485 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
487 * The server's silc_server_save_channel_key now checks also the
488 global ID list for the channel as it might not be in the local
489 list. Fixed a bug related to LEAVE command.
491 * Is this the end of the [<unknown>] buglet that has been lurking
492 around for a long time? A little for loop fix in server's
493 silc_server_command_whois_parse that is used by both IDENTIFY
494 and WHOIS command. At least, this was a clear bug and a cause
495 of one type of [<unknown>] buglet.
497 * WHOIS and IDENTIFY commands call the function
498 silc_server_command_[whois/identify]_check function even if
499 we are not router server.
501 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * Added --with-gmp configuration option. If set the GMP
504 is always compiled in the SILC source tree. If not set then
505 it is checked whether the system has the GMP3 installed. If
506 it has then the GMP won't be compiled (the system's headers
507 and library is used), if it doesn't have it then the GMP is
508 compiled in the SILC source tree.
510 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Changed RSA private exponent generation to what PKCS #1
513 suggests. We try to find the smallest possible d by doing
514 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
515 not security fix but optimization.
517 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Added new config entry [Identity] to fork the server and run
520 it as specific user and group. A patch from Bostik.
522 * Imported Dotconf configuration library into lib/dotconf.
523 This will be used to create the SILC configuration files later.
524 It will appear in the distsribution after this commit.
526 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * A big code auditing weekend happening. Auditing code for
529 obvious mistakes, bugs and errors. Also, removing any code
532 Removed files for being obsolete:
534 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
535 inline in the file lib/silcutil/silcbuffer.h)
537 o lib/silcutil/silcbufutil.c (the header has inline versions)
539 Changed code to fix possible error conditions:
541 o The buffer formatting routines now check that the destination
542 buffer really has enough space to add the data. This applies for
543 both buffer formatting and unformatting
544 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
545 unformatting was changed to accomodate following rules:
546 XXX_*STRING_ALLOC will allocate space for the data into the pointer
547 sent to the function while XXX_*STRING will not allocate or copy
548 the data into the buffer. Instead it sets the pointer from the
549 buffer into the pointer sent as argument (XXX_*STRING used to
550 require that the pointer must be allocated already). This change
551 makes this whole thing a bit more consistent and more optimized
552 (note that the data returned in the unformatting with XXX_*STRING
553 must not be freed now). The routines return now -1 on error.
555 o Tried to find all code that use buffer_format and buffer_unformat
556 and added return value checking to prevent formatting and
557 especially unformatting errors and possible subsequent fatal
560 o Changed ske->x and ske->KEY to mallocated pointers in
561 lib/silcske/silcske.h. Fixed possible data and memory leak.
563 o Added return value checking to all *_parse* functions. Fixed
564 many memory leaks as well.
566 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
567 so that buffer overflows would not happen. All code now also
568 checks the return value as it can fail.
570 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
572 * Added reconnection support to server if the normal server looses
573 its connection to the router (for example if router is rebooted).
574 The server performs normal reconnection strategy implemented
575 to the server. Affected file silcd/server.c.
577 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * Added new packet type SILC_PACKET_SET_MODE that is used to
580 distribute the information about changed modes (for clients,
581 channels and clients channel modes) to all routers in the
582 network. Updated the protocol specification accordingly.
584 Added functions into silcd/packet_send.c and
585 silcd/packet_receive.c: silc_server_send_set_mode,
586 silc_server_set_mode.
588 Added new files silcmode.[ch] into lib/silccore that implements
589 the encoding and decoding of Set Mode Payload. Added new type
590 SilcSetModePayload. Moved the definitions of different modes
591 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
593 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Oops, a little mistake in server's connection authentication
596 protocol. The protocol is not ended with FAILURE but with
597 SUCCESS if the authentication is Ok. :) Affected file is
600 * Implemented NICK_CHANGE notify handling in server in the file
601 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
602 the local clients on the channel. After the changing nickname
603 in router environment snhould work and the [<unknown>] nickname
604 should appear no more.
606 The silc_server_replace_id function that receives the Replace ID
607 payload now sends the NICK_CHANGE notify type also in the file
608 silcd/packet_receive.c
610 * Changed WHOIS and IDENTIFY command to support the maximum amount
611 of arguments defined in protocol specs (3328 arguments). This
612 fixed a bug that caused problems when there were more than three
615 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
617 * Added extra parameter, command identifier, to the
618 silc_client_send_command so that explicit command identifier
621 Changed that ID list routines uses specific command identifier
622 when sending WHOIS/IDENTIFY requests to the server so that they
623 can be identified when the reply comes back.
625 Affected files lib/silcclient/command.[ch],
626 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
628 * Added `sender' argument to silc_server_packet_send_to_channel
629 to indicaet the sender who originally sent the packet to us
630 that we are now re-sending. Ignored if NULL. Affected file
631 silcd/packet_send.[ch].
633 * Added some server statistics support in silcd/server_internal.h
634 SilcServerStatistics structure and around the server code. Also
635 send some nice statistics information when client is connecting
638 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Fixed channel ID decoding in server's JOIN command reply in
641 silcd/command_reply.c
643 * Fixed braodcasting of replace ID payload to not to send it if
644 we are standalone server in silcd/packet_receive.c.
646 * Fixed all channel message sending routines to not to send
647 packets to clients that has router set, since they are routed
648 separately in the same function earlier. Affects file
649 silcd/packet_send.c and all channel packet sending functions.
651 * In USERS reply, res_argv[i] are not allocated, the table
652 is allocated. Thus changed that free the table, not its
655 * In server's whois_check and identify_check if the client is
656 locally connected do not send any WHOIS commands - they are not
659 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Fixed some minor bugs in client when sending WHOIS command. The
662 arguments was in wrong order.
664 * Removed statis function add_to_channel from server in
665 silcd/command.c that was previously used with the joining but
668 * Tested USERS command in router environment successfully with two
669 routers, two servers and two clients.
671 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Reorganized the USERS command and command reply in client library
674 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
675 When the command is given by user we register a pending command
676 callback that will reprocess the command after the reply has been
677 received from the server. When reprocessing the packet we then
678 display the information. Thus, the USERS information is displayed
679 now in the command callback instead of in the command reply
680 callback. The processing of the command is same as previously
681 when server has sent the command reply in the JOINing process.
683 * Added to USERS command in silcd/command_reply.c to join the client,
684 we didn't use to know about, to the channel after we've created
685 a client entry for it. Also, for clienet we did know already still
686 check whether it is on the channel or not and add it if not.
688 * Removed silc_server_command_join_notify as the function and its
691 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
693 * Changed the client's pending command handling to the same as the
694 server's pending command handling. It is also now possible to
695 execute command reply functions from other command reply
696 function as the function callbacks for commands and command
697 replies are one and same. The pending commands are not static
698 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
699 in client connection context. Thus, pending commands are server
700 connection specific as it is convenient.
702 Changed the function silc_client_command_pending and
703 silc_client_command_pending_del and added new function
704 silc_client_command_pending_check. Removed the
705 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
708 * Added cmd_ident, current command identifier, to the client
709 connection context in lib/silcclient/client.h to keep track on
710 command identifiers used in command sending. Client's command reply
711 function handling now supports the mandatory command identifiers.
713 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
714 funtions in client to fully support pending command callbacks.
716 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
717 as one of the arguments to the application in the command reply
720 * NOTE: The FORWARDED flag is depracated. It used to be depracated
721 before first releasing SILC but came back. Now it is removed again
722 and should come back nomore. The FORWARDED flag was used only
723 by the JOINing procedure by forwarding the command packet to router.
724 Now, the JOINing procedure has been changed to more generic (due
725 to various router environment issues) and FORWARDED is not needed
726 anymore for anything. The protocol specification is yet to be
729 Now, removed silc_server_packet_forward from server and the flag
730 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
732 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * Renamed NAMES command to USERS command. The NAMES was named that
735 due to historical reasons. Now it is renamed. Also, rewrote
736 parts of the USERS command. The nickname list is not sent anymore
737 by the server. Only Client ID and mode lists are sent in the USERS
738 command. Changed this also to the protocol specification.
740 The client now resolves the names and stuff after it receives
741 the USERS list from the server when joining to the channel.
743 * WHOIS and IDENTIFY commands has been changed to support multiple
744 Client ID's per command. One can now search for multiple users
745 in the network by sending only one WHOIS or IDENTIFY command.
746 Changed the code and the protocol specifications.
748 * Removed silc_server_command_identify_parse and changed that IDENTIFY
749 uses silc_server_command_whois_parse to parse the request. */
751 * If normal server, do not parse the WHOIS and IDENTIFY requests
752 before sending it to the router. Saves some time.
754 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Fixed JOIN command on client library. Wrong number of arguments
757 used to crash the client.
759 * Added silc_server_channel_has_global function to check whether
760 channel has global users or not.
762 * Added silc_server_channel_has_local function to check whether channel
763 has locally connected clients on the channel.
765 * The silc_server_remove_from_one_channel now checks whether the
766 channel has global users or not after given client was removed from
767 the channel. It also checks whether the channel has local clients
768 on the channel anymore. If it does not have then the channel entry
769 is removed as it is not needed anymore.
771 * The silc_server_notify now checks on JOIN notify whether the joining
772 client is one of locally connected or global. If it is global then
773 the channel has now global users on the channel and that is marked
774 to the channel entry. Also, it now saves the global client to
775 global list who is joining and JOINs it to the channel. This is
776 for normal server, that is.
778 Changed silc_server_send_notify_on_channel,
779 silc_server_packet_relay_to_channel and
780 silc_server_packet_send_to_channel check if we are normal server
781 and client has router set (ie. global client) do not send the
782 message to that client, as it is already routed to our router.
784 * Implemented LEAVE notify type handling in silc_server_notify
787 * Tested LEAVE command in router environment successfully. Tested
788 with two routers, two servers and two clients.
792 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
794 * Implemented SIGNOFF notify type handling in silc_server_notify
797 * silc_server_remove_id now removes the client entry from all channels
798 it has joined and thusly sends SIGNOFF notify type.
800 * Rewrote the NAMES list generation in server by removing two excess
801 loops. The lists are created now inside one loop.
803 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
805 * silc_server_remove_channel_user checks now also global list
806 for channel and client.
808 * silc_server_new_channel_user checks now both local and global
809 list for channel and client. Fixed a bug in client id decoding.
810 Used to decode wrong buffer.
812 * silc_server_channel_message checks now both local and global
813 list for channel entry.
815 * Tested channel joining (hence JOIN) in router environment
816 successfully. Tested with two routers, two servers and two
819 * Tested channel message sending in router environment successfully.
821 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Added silc_server_save_channel_key into server.[ch] to save the
824 received channel key in Channel Key payload processing. It is
825 also used in JOIN command reply handling.
827 Equivalent function silc_client_save_channel_key added into
828 client.[ch] into client library.
830 * Changed JOIN command reply to send information whether the channel
831 was created or not (is existing already) and the channel key
832 payload. Changed protocol specs accordingly.
834 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
835 the request was sent by ID and not by nickname. Crashed on
838 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
841 now correctly save the received data.
843 * silc_server_free_sock_user_data now notifies routers in the
844 network about entities leaving the network.
846 At the same time implemented functions silc_server_remove_id
847 and silc_server_send_remove_id to receive and send REMOVE_ID
848 packets. The packet is used to notify routers in the network
849 about leaving entities. The ID removed will become invalid in
852 * Added function silc_idlist_del_server into server. Removes and
853 free's server entry from ID list.
855 * silc_server_private_message function now checks, if we are router,
856 that the destination ID really is valid ID, naturally.
858 * In router when NEW_ID packet is received (for new client) the
859 hash of the Client ID is saved in the ID Cache but the
860 client->nickname is set to NULL, instead of putting the hash
863 IDENTIFY command now also checks that client->nickname must be
864 valid. If it is not if will request the data from the server who
865 owns the client. Added new function
866 silc_server_command_identify_check.
868 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
869 to set the command to already allocated Command Payload.
871 * Tested private message sending in router environment with two
872 routers, two servers and two clients. Fixed minor bugs and now
875 * Fixed segfault from client's NAMES command. Used to crash if
878 * Forwarded packets must not be routed even if it is not destined
879 to the receiver. Changed server code comply with this.
881 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
883 * Added `require_reverse_mapping' boolean value to ServerParams
884 structure. If TRUE (not default) the server will require that
885 the connecting host has fully qualified domain name.
887 If the reverse mapping is not required and hostname could not be
888 found the IP address is used as hostname.
890 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
892 * Implemented version string checking to both client and server.
893 The check is incomplete currently due to the abnormal version
894 strings used in development version of SILC.
896 * Changed all command functions in server to use the new
899 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
901 * Changed char *data to unsigned char *data in ID Cache system to
902 support binary data as ID Cache data. Changed code to support
903 binary data in lib/silccore/idcache.c.
905 * Renamed silc_server_packet_relay_command_reply to
906 silc_server_command_reply as it is normal packet receiving
907 function. Rewrote the function to accept command replys for
908 servers and not only for clients.
910 * Mark remote router always as registered server if we are connecting
911 to it. Otherwise, commands sent by the router to us are ignored.
913 * All ID List find routines now returns the ID Cache Entry pointer
914 as well if requested.
916 * WHOIS command works now in router environment, tested with two
917 routers, two servers and two clients.
919 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
920 in router environment (as it is almost equivalent to WHOIS) but
921 hasn't been tested thoroughly. Added new functions:
923 silc_server_command_identify_parse
924 silc_server_command_identify_send_reply
925 silc_server_command_identify_from_client
926 silc_server_command_identify_from_server
928 * Disabled route cache adding because adding two different ID's with
929 same IP replaces the old cache entry thus giving wrong route.
930 The entry->router->connection is always the fastest route anyway
931 so route cache may not be needed. Of course, new routes maybe
932 established after receiving the ID when the entry->router->connection
933 might not be anymore the most optimal.
935 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Add route cache for received ID for fast routing.
939 * Added silc_server_packet_route to route received packet on router
940 that is not destined to us.
942 * Renamed silc_server_get_route to silc_server_route_get.
944 * Added id_string and id_string_len fields into SilcServer to
945 include encoded ServerID for fast comparing without excess
946 encoding of the ID's.
948 * Cleaned up WHOIS command on server side. Added following static
951 silc_server_command_whois_parse
952 silc_server_command_whois_check
953 silc_server_command_whois_send_reply
954 silc_server_command_whois_from_client
955 silc_server_command_whois_from_server
957 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
958 arguments in command replies. All command functions should be
959 updated to use this macro.
961 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Minor typo fixes on command reply handling on server.
965 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * Added silc_server_command_add_to_channel internal routine to add
968 the client to the channel after router has created the channel and
969 sent command reply to the server.
971 * Added generic silc_server_send_command to send any command from
974 * Use static buffer with ID rendering instead of duplicating data.
976 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Fixed a channel user mode bug when joining to a channel server gave
979 everybody channel founder rights, oops.
981 * We mark ourselves as the router of the incoming server connection
982 if we are router ourselves. This way we can check in some packet
983 sending functions whether it is locally connected server. For
984 incoming router connections we put NULL.
986 * For router sending packets locally means now always sending the
987 packet cell wide; to local clients and local servers. For normal
988 server sending packet locally means sending it to only local
991 * Fixed the JOIN command to really work in router environment. If the
992 channel is created it is always created by the router. Router is
993 also responsible of making the initial joining to the channel,
994 sending JOIN notify to the sending server and distributing
995 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
996 does not exist server doesn't do anything else but forward the
997 command to the router which performs everything.
999 * Added silc_server_send_channel_key function to send the Channel Key
1002 * Added silc_server_create_channel_key to create new channel key. The
1003 channel key is now re-generated everytime someone joins or leaves
1004 a channel, as protocol dictates. Note: channel->key_len is the
1007 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1010 packet_receive.[ch] to separate packet sending and receiving
1011 routines. The server.[ch] now includes everything else including
1012 actual packet processing (writing and reading data) and other
1015 Renamed silc_server_private_message_send_internal to
1016 silc_server_send_private_message. The routine is still though
1017 used only to relay private messages as server does not send
1018 private messages itself.
1020 Renamed silc_server_new_channel to silc_server_create_new_channel
1021 and added new function sicl_server_new_channel that handles the
1022 incoming New Channel packet. Added also new sending function
1023 silc_server_send_new_channel to send New Channel Payload.
1025 * Added new function silc_server_notify to process incoming notify
1026 packet to the server/router. Server may then relay the notify
1027 to clients if needed.
1029 * Added new function silc_server_new_channel_user to process incoming
1030 New Channel User packet. Router will redistribute the packet and
1031 send JOIN notify to its local clients and locally connected servers
1032 if needed. Normal server will send JOIN notify to its local client
1033 on same channel when received this packet. Added also corresponding
1034 sending function silc_server_send_new_channel_user to sent the
1037 * Added boolean route argument to send_notif_to_channel and
1038 packet_send_to_channel functions to attempt to route the packet
1039 if it is TRUE and send only locally if it is FALSE.
1041 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1043 * silc_server_replace_id now broadcasts the received replace ID
1044 packet if it is not broadcast packet already. The router must
1045 broadcast to inform other routers about changed ID.
1047 * Added backpointer to server's router into SilcServer context in
1048 silcd/server_internal.h.
1050 * Fixed silc_server_packet_broadcast to send correct broadcast
1053 * The channel key is now distributed to the local client as soon
1054 as it is received from the router (in router environment) so that
1055 no other packet may be sent for the channel until client has
1058 * silc_server_remove_channel_user now broadcasts the received
1059 Remove Channel User packet if it is not broadcast packet already.
1060 The router must broadcast to inform other routers about removed
1063 * Added users field into SilcPacketContext that is a reference count
1064 of the context. One can increase the reference count by calling
1065 silc_packet_context_dup which is now changed to just increase the
1066 reference count instead of duplicating the data. The reference
1067 count is decresed by calling silc_packet_context_free that will
1068 free the data after the reference count hits zero.
1070 For now on the packet context and everything allocated into it
1071 (including the raw packet from network) must be freed by calling
1072 the new silc_packet_context_free function. Added also new function
1073 silc_packet_context_alloc that must be used now to allocate the
1074 context. This also means that if a routine is asynchronous from
1075 silc_[client/server]_packet_parse_type the packet context must
1076 be duplicated by calling silc_packet_context_dup. Otherwise it
1077 gets free'd after silc_[client/server]_packet_parse_type returns.
1078 Also, one must remember that if packet is duplicated then its
1079 reference count must be decresed by calling the free function as
1080 many times as it was duplicated.
1082 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1083 from both client and server.
1085 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Made joining to a channel working in router environment.
1089 * Cleaned up JOIN command on server side and create function
1090 silc_server_command_join_channel internal routine to make the
1093 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Changed silc_command_pending list to SilcDList. Also, added
1096 `ident' field to SilcServerCommandPending structure to identify
1097 the reply and to call correct callback.
1099 Added silc_server_command_pending_check function to replace the
1100 corresnponding macro. The silc_command_pending list is not
1103 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1104 to set identifier to previously allocated Command Payload. It
1105 is used to set identifier for command when resending Command
1108 * Added silc_command_payload_encode_payload to encode Command
1109 Payload buffer from SilcCommandPayload structure.
1111 * Added silc_argument_payload_encode_payload to encode Argument
1112 payload buffer from SilcArgumentPayload structure.
1114 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1116 * Changed WHOIS command to support router connection on server side.
1117 The whois request is always sent to router unless the server is
1118 standalone server. After server has received the reply from the
1119 router will it send the reply to the client.
1121 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1122 broadcast received broadcast packet. The function is used only
1123 by router. The broadcast packet is always sent to the router's
1126 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1127 render given ID to printable string, for log files for example.
1129 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Made basic router to router connections working. At least they
1132 can now connect to each other but nothing really works the way
1133 they are supposed - yet.
1135 * Added new initiator token to RouterConnection configuration
1136 file in silcd/serverconfig.[ch]. It is used to tell whether we
1137 are the initiator to the remote router or whether we'll expect
1138 the other end to connect.
1140 * Moved registering of listener task to silc_server_init, hence
1141 the server starts listenning as soon as it is run, even if it
1142 does not have connections to other routers. Let's see how well
1145 * Changed default connection retry timeouts for more suitable in
1148 * Removed cipher and such arguments from silc_idlist_add_client
1149 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1150 Added new function silc_idlist_add_data to add the keys and stuff
1153 * Added SilcIDListData structure and added it to SilcClientEntry
1154 and SilcServerEntry as their first field in the structure. This
1155 way we can explicitly cast the ID entries to the SilcIDListData
1156 structure and get common data for the entries. In past, we had
1157 to first check what type of connection it is and then cast it to
1158 correct ID entry type. Now, we can directly cast the opaque
1159 pointer to the SilcIDListData (no matter what ID entry it actually
1160 is) and get the data needed.
1162 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1165 in some circumstances even if threre were timeout tasks, though not
1166 IO tasks, but tasks anyway. Now fixed.
1168 * Defined SilcServerConnection structure to hold connection specific
1169 stuff about directly connected servers and routers. The definition
1170 is currently in silcd/server_internal.h. I thought about having
1171 a bit more important role fro this struct but for now it is used
1172 only when connecting to other server (or router actually).
1174 * Added connecting retry support in server when connecting to
1175 router(s). The retry feature implement exponential backoff
1176 algorithm. Also, added SilcServerParams structure to hold default
1177 parameters for server. For now, it include these retry settings
1178 and are hard coded. After server is moded to be as Silc Server
1179 Library this structure will be more important.
1181 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1183 * Changed client librarys channel->clients table to SilcList and
1184 changed code accordingly.
1186 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1188 * Changed client's channel table to SilcList and changed code
1189 accordingly. Also changed SilcChannelClientEntry to include back-
1190 pointer to the channel so that client entry can use that structure
1191 as list as well and we have fast cross-reference to the channel.
1192 This change dramatically decreased the complexity of channel
1193 handling with client entry and vice versa (removed one extra
1194 loop when searching for channel entry from many functions).
1196 * Changed server->sim from table to SilcDList and changed code
1199 * NAMES command can now be used from user interface. It will show
1200 the user list on the channel, neatly.
1202 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1203 Code now saves realname of the user if it becomes available.
1205 * Renamed configure.in to configure.in.pre and made ./prepare
1206 script to automatically add correct version string to
1207 configure.in which it creates from configure.in.pre.
1209 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1211 * NAMES command reply now shows users mode with the nickname when
1214 * Moved silc_client_ch[u]mode[_char] functions from
1215 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1216 place sucks, they are utility functions and should be in some
1219 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1221 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1224 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1228 * Added TRQ (efficient deque and list library) into lib/trq. This is
1229 a very good list library that is currently used in the SILC. Defined
1230 SilcList API over the library because I didn't like the API very
1231 much. See lib/trq/silclist.h for the API and examples of how to
1232 use the API. Fixed various places in the code to use the new
1233 SilcList API. The SilcList is meant for lists that has a structure
1234 already defined as a list. It is not suitable to add just some
1235 context to the list (in TRQ, the context is the list actually).
1237 So, I defined SilcDList that can be used for the purpose where
1238 predefined list structure does not exit. This can be used as
1239 such list. Now some context just can be added to the SilcDList.
1240 Currently this list is not used in the SILC just yet, though there
1241 are a lot places where this can replace dynamically allocated
1242 tables and I will fix these places, later, to use SilcDList.
1243 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1244 and use TRQ internally).
1246 Also fixed some annoying warning messages that the original TRQ
1247 code generated. Also minor changes to TRQ's Makefile.in.
1249 * Added support for querying by Client ID to both WHOIS and
1250 IDENTIFY commands into server, as required by the protocol.
1252 * Removed method function pointers from SilcBuffer structure. They
1253 weren't used to anything and just increased the context size for
1254 no good reason. This change also made silc_buffer_alloc and
1255 silc_buffer_free functions inline functions.
1257 * Disabled command flooding detection support until it's fixed so
1258 that it accepts commands in but does not execute them more than once
1261 * Added silc_net_localhost(), to return local hostname, into
1262 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1263 that must be initialized before calling silc_client_init.
1265 * Added new function: silc_server_send_notify_on_channels to send
1266 notify messages to all channels client has joined. It is assured
1267 that the message is sent only once per client.
1269 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1270 lib/silcutil/silcutil.[ch] as silc_format function. The new
1271 function is generic and is used by server as well, not only by
1272 the logging routines.
1274 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1275 the provided version string was not acceptable. Added new function:
1276 silc_ske_check_version into lib/silcske/silcske.h. The function
1277 must be implemented by the application (client or server) and it
1278 does not reside in the SKE library. The function checks the version
1279 string remote end sent.
1281 * Added back pointers (to opaque context and to SilcSocketConnection)
1282 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1284 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1285 duplicate packet context structure.
1287 * Changed `notify' client operation to send same arguments as client
1288 receives from server except for ID's. ID's are mapped to correct
1289 ID entry and that is returned. Also, if channel entry is not sent
1290 by server but the notify is for channel the channel entry is sent
1291 to application (otherwise application doesn't know that it is for
1292 channel (library gets it from packet's Destination ID)).
1294 * Added silc_client_remove_from_channels into client library to
1295 remove a client from all channels it has joined to. Used when
1296 received SIGNOFF notify from server. Added also new function
1297 silc_client_replace_from_channels to replace old ID entry with
1298 new ID entry on all channels. Used when received NICK_CHANGE
1301 * Fixed ID Cache list handling in silc_idlist_get_client in
1302 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1303 to get (or query) client by ID.
1305 * Updated TODO list.
1307 * Added connection authentication status message defined by the
1308 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1309 support for these into the code in client and server side.
1311 * Added generic function silc_client_send_command to send any command
1312 with variable argument list. Application should use this function
1313 to send commands if the command functions provided by the library
1314 does not suite for the application's user interface needs.
1316 * Added new `failure' client operation. Application is notified about
1317 received failure packet if client is executing a protocol. In this
1318 case the protocol's execution has failed.
1320 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1321 is required by the protocol.
1323 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1324 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1327 * Added status flag to SilcSKE object to indicate realtime status
1328 of the SKE protocol.
1330 * Application receives now exactly same command reply arguments as
1331 the library receives from server. However, if ID is received the
1332 corresponding ID entry is returned to the application (eg. Client
1333 ID is mapped to correct SilcClientEntry entry and that is returned).
1334 Changed command_reply client operation due to this change.
1336 * Changed all ID's in commands and in command replys as ID Payloads.
1337 Change affected both client and server side codes.
1339 All ID's sent in SILC network (with execption of ID's in SILC
1340 Packet header) are sent in ID Payload to support variable length
1343 * Server now notifies nick changes and notifies all clients on
1344 the channels about the new nickname (about the new Client ID,
1347 * Implemented CMODE command to change channel modes. Supports all
1348 channel modes defined by the protocol specs except ban and invite
1349 lists. (Also, private channel key mode is supported but support for
1350 setting private channel key in client is missing, thus, this mode
1351 has no effect on client side (except that server requires that the
1352 client uses private channel key and normal channel traffic does not
1355 Also, invite mode works per se, but INVITE command does not work
1356 yet correctly, so you can set channel as invite only channel but
1357 inviting clients to the channel does not work (it is yet to be
1358 thought what's the best way to do it).
1360 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1361 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1362 Implemented CUMODE command to change user's mode on the channel.
1363 Supports all modes defined by the protocol specs.
1365 * Added NAMES command reply to return users modes on the channel.
1367 * Removed unnecessary and slow ciphers from lib/silccrypt.
1369 * Set SO_KEEPALIVE option to connection sockets by default.
1371 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1373 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1374 redefined the Notify Payload into protocol specs.
1376 * Added silc_id_payload_parse_id to get ID directly from raw
1379 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1381 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1382 accept searching by Client ID as well.
1384 * Added support for LEAVE and SIGNOFF notify types in client library.
1386 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1387 to parse ID Payload from raw data.
1389 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1391 * Added flags parameter into silc_ske_assemble_security_properties
1392 function in lib/silcske/silcske.[ch].
1394 * Changed notify client operation to fit better for notify messages
1395 sent by server. The notify payload received from server is now
1396 passed to the application (after parsing it to SilcNotifyPayload).
1397 It is application's responsibility to retrieve the arguments
1398 from the payload and show the message the way it wants. The message
1399 sent by server is implementation specific.
1401 * Changed public keys to comply with the protocol specification.
1402 Old public keys are not supported anymore and are not compatible.
1404 * Removed nickname from Channel Payload as the latest draft removed
1405 it. The client must resolve the nickname from the NAMES command
1406 reply received when it joined the channel.
1408 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1410 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Fixed some errors in protocol specification drafts.
1414 * Created lib/silccore/silcnotify.c to implement Notify Payload
1415 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1416 generic payloads described by protocol specifications. The file
1417 includes implementations for ID Payload and Argument Payload.
1419 * Changed Command Payload implementation to use the new Argument
1420 Payload. Changed command_xxxx_payload to command_payload_xxxx
1421 to comply with SILC coding conventions.
1423 * Added suppport for Argument Payload handling in Notify Payload
1424 implementation as protocol requires it. Added the new support
1425 into server and client lib as well.
1427 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Added support for multiple nicknames on same channel. [n] is
1430 added locally to the nickname if there are more than one same
1431 nicknames on the channel.
1433 * Server now sends all nicknames that matched WHOIS request.
1434 Client also shows the list received from server.
1436 * Added TOPIC command to client side. User can now set and show
1437 current topic on channel.
1439 * Added MOTD command to client and server. Also, server sends the
1440 motd when client connects to the server.
1442 * Changed version strings to comply ISO 8601.
1444 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Fixed protocol error handling in client library. It should now
1447 cope even if the SKE fails for some reason.
1449 * Made new protocol specification drafts for submitting to IETF.
1451 * Implemented TOPIC command to server in silcd/command.c.
1453 * Added two new notify types into lib/silccore/silcnotify.h:
1454 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1455 notify nickname change and topic setting/change on a channel.
1457 * API change of command_reply operation in client library. The
1458 application gets now the status type received from server as well.
1460 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1462 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1464 * Cras fixed and optimized the packet handling even further and
1465 it should work now. Minor change to the prototype of function
1466 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1468 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1470 * Added new function into lib/silcutil/silcschedule.[ch]:
1471 silc_schedule_with_fd to select() a specified fd. The function
1472 returns after timeout expires or data arrives or goes. The
1473 function is used by packet routines to wait that all data is
1474 received from network.
1476 * Fixed data reading from network in lib/silccore/silcpacket.c.
1477 The code now assures that all data is read from the fd and then
1478 continues packet processing. This was a bug fix since the code
1479 used to drop some data in some circumstances.
1481 * Added new function into lib/silcclient/client.[ch]:
1482 silc_client_start_key_exchange to start key exchange after
1483 connection has been established to server. The code internally
1484 now uses this funtion but its main purpose was to provide it
1485 for applications that perform their own connecting. After
1486 application has created a connection it merely calls this
1487 function to start the key exchange between client and server.
1488 The library takes care of everything else after that.
1490 Updated also lib/silcclient/README to explain the usage of
1493 * Do not send to application information that connection has
1494 been established. Application gets notified it by connect
1497 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1499 * Applied cras's patch to add silc_schedule_one function. The
1500 function runs scheduler once and returns.
1502 * Fixed the scheduler after cras messed it up. The timeout
1503 handling works now as it's supposed to work.
1505 * Added into lib/silccore/ silcnotify.h to include notify
1506 message types support. Changed silc_server_send_notify*
1507 functions, in server.[ch], to support those new notify types.
1508 Added the support for the notify types into client library,
1509 as well. Added new notify client operation into ops.h in
1512 * Changed silc_server_packet_send_to_channel to send normal
1513 packets instead of just channel message packets. The function
1514 is now used to send the notify packets to channels. It is not
1515 used to send channel message packets anymore, as server never
1518 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1519 va_arg()s as it seems to require it nowadays. I guess, if SILC
1520 is compiled with older va_arg() the new code should work anyway.
1522 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1524 * Splitted core library. Core library (lib/silccore) includes
1525 now only SILC protocol specific core (and common) components.
1526 Created new utility library (lib/silcutil) that includes more
1527 generic purpose stuff. The stuff for util library was taken
1528 from the old core library. This was minor and easy split.
1530 * Created SILC Client Library (lib/silcclient) that includes
1531 implementation of the SILC client without user interface. This
1532 was major move from silc/ directory. The code has been changed
1533 so that it is transparent towards the user interface. The
1534 silc/ directory includes now the same user interface as before
1535 and it uses the new client library. Read lib/silcclient/README.
1536 Basicly, the client library performs everything else related
1537 to SILC except user interface handling. Also, configuration
1538 files are considered to be part of user interface and library
1539 does not handle them.
1541 This change also changed a lot of structures, function naming etc.
1542 Most important change was that SilcClientWindow object was
1543 renamed to SilcClientConnection in the client library. Created
1544 also new file lib/silcclient/ops.h. Also added new files
1545 silc/local_command.[ch] and silc/client_ops.[ch].
1547 All these changes were made to make it easier for user interface
1548 designers to create what ever user interface for the SILC client
1551 It is also expected that the server will be moved to lib
1552 directory as well and SILC Server Library will be created;
1553 sometimes in the future.
1555 * Removed Local commands from lib/silccore/silccommand.h as
1556 they are application specific and new client library does not
1557 handle any of those anymore.
1559 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1560 old client implementation in silc/.
1562 * Added support for callback functions in SILC_LOG_* macros.
1563 Application can now set its own callbacks that will be called
1564 instead of using the default functions that will always print
1565 the debug messages to stderr (or stdout). Also, debugging can
1566 now be disabled by setting silc_debug to FALSE and re-enabled by
1567 setting it to TRUE. Note, that logging will still work even
1568 if debugging is disabled.
1570 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1571 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1572 silc_log_reset_debug_callbacks.
1574 * To enable debugging in silc client one must give now -d
1575 option on command line.
1577 * Changed silc_schedule_init to automatically allocate task queues
1578 if they are not allocated before calling it.
1580 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Added GMP 3.1 into math library.
1584 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1587 a channel in SILC network. The packet is used by servers and
1588 routers to notify other routers that user has left a channel.
1589 This little feature was missing until now. Added the feature
1590 to protocol specification as well.
1592 Added functions: silc_server_send_remove_channel_user and
1593 silc_server_remove_channel_user into server.[ch].
1595 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1596 lib/silccore/silcpacket.h. However, they are not implemented
1599 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Fixed joining to a channel and sending channel messages
1602 between server and router. The channel message sending should
1603 now work inside a cell.
1605 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Fixed the private message sending between server and router.
1608 The private message sending should now work inside a cell.
1610 * Added silc_server_replace_id into server.[ch] to replace
1611 existing ID in the SILC network.
1613 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1614 and silc_idlist_replace_server_id into idlist.[ch] in server.
1616 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Fixed the server to server connections. Server can again now
1619 connect to router. Router to router connections probably does
1622 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * Added dynamic protocol registering support. Now protocols can
1625 registered and unregistered on the fly. Patch by cras.
1627 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1629 * Added lib/contrib directory to hold routines that some platforms
1630 don't have but are needed by SILC.
1632 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1633 into lin/contrib to provide getopt() and getopt_long() for
1634 those who don't have it.
1636 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Added AWAY command to client. When away message is set and
1639 client receives a private message packet the client automatically
1640 replies to the sender with the away message.
1642 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1643 bug seemed to be the cause of recent problems when compiling
1646 * Added version detection support to SKE protocol specification
1647 and added the new changes to the SKE implementation as well.
1648 There were other minor changes in the SKE protocol as well.
1650 Many changes in lib/silcske/silcske.[ch] and in
1651 lib/silcske/payload.[ch].
1653 * Added ^U functionality, clear input line. Patch from cras.
1655 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Mainly small bugfixes on core library. Fixed some debugging
1658 logging and buffer overflow in silclog.c.
1660 * Updated config.sub and config.guess on the distribution tree.
1662 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Added command lagging support in server. Client may execute
1665 commands now only once in two seconds.
1667 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Optimized packet reception. MAC computation and checking is now
1670 also more optimized. A lot previously duplicated code is now
1671 used as generic by both client and server.
1673 * Fixed key pair generation in clientutil.c
1675 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Added into lib/silccore/silcbufutil.[ch] new function;
1678 silc_buffer_realloc.
1680 * Moved generic packet sending/encryption functions to
1681 lib/silccore/silcpacket.[ch] from client and server. Some
1682 rewriting of the functions.
1684 * Moved all generic packet reception/decryption functions to
1685 lib/silccore/silcpacket.[ch] from client and server. The
1686 packet processing is now much cleaner in both client and server.
1687 These were major changes in both client and server.
1689 * Created many common functions in server to do packet sending.
1690 Previously code were duplicated a lot, this has been removed
1693 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1695 * Rewrote major parts of the ID cache system. Don't know
1696 whether it is better now or not but at least the API is more
1699 * Major rewrite on ID cache stuff on client because of the ID
1700 cache API changes. Added idlist.c to client.
1702 * Also major rewrite on ID cache stuff on server as well.
1703 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1704 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1705 in hand, instead they are all put into the ID cache system now.
1706 All server_idlist_* routines uses ID cache now instead of
1707 traversing its own lists (those lists does not exist anymore).
1708 SilcIDList though still exists. Also, SilcXXXEntry's are
1711 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Finally made the SKE implementation compliant to the protocol
1714 specification. All mp integers are now binary encoded as
1715 opposed being HEX encoded.
1717 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1720 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1721 functions: silc_[encode/decode]_pem. Also added function
1722 silc_encode_pem_file to PEM encode with newlines ('\n') for
1725 * SILC public keys are now encoded either PEM or binary. Same
1726 option is for private keys as well. By default private keys
1727 are binary encoded and public keys PEM encoded. Silly HEX
1728 encoding were removed.
1730 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1731 function to create fingerprints.
1733 * Fixed a bug in SHA1; does not change the original data anymore.
1735 * Partly implemented INFO command on client and server side.
1736 Fixed CLEAR command. Changes to SERVER command; show current
1737 server(s) when giving command without arguments. Added
1738 VERSION command to client.
1740 * Added check to server that unregistered connections cannot
1741 execute commands (unless it is specificly allowed).
1743 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1745 * Fixed screen refresh.
1747 * Fixed channel joining bug from client. On some circumstances
1748 client tried to join to a channel it had already joined.
1750 * Added public key verification process into client's protocol.c.
1751 The client now verifies the public key from user and saves
1752 it into ~./silc/serverkeys/ directory.
1754 Added into: clientutil.[ch]: silc_client_verify_server_key.
1756 * Changed SKE protocol's silc_ske_initiator_finish function
1757 to accept callback function that verifies the received public
1758 key. Removed old silc_ske_verify_public_key function.
1760 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1763 silc_pkcs_private_key[_data]_set.
1765 * Made the password and public authentication more cleaner in
1766 server's protocol.c.
1768 * Removed historic and obsolete protocol `channel_auth' from
1769 both client and server.
1771 * Removed wrong way of sending command status messages from
1772 server to client in server's command.c. The old way violated
1773 protocol specification.
1775 Changes to silccore/silccommand.[ch]: removed
1776 silc_command_encode_status_payload -> not needed anymore,
1777 changed silc_command_encode_payload_va to accept extra
1778 argument on variable argument list. The argument type must
1779 now be provided to the function. Also, added new function:
1780 silc_command_encode_reply_payload_va which is same as
1781 normal command_encode_payload_va except command status type
1782 is provided as extra argument.
1784 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1786 * Added ~./silc directory handling. The directory includes the
1787 public and private keys for the client.
1789 Added silc_client_check_silc_dir, silc_client_create_identifier
1790 and silc_client_load_keys.
1792 * Implemented SILC protocol compliant public key. Added public
1793 and private key saving to and loading from files.
1795 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1796 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1797 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1798 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1799 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1801 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1802 silc_pkcs_load_[public/private]_key.
1804 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1806 * Added silc_server_get_route (route.[ch]) to get connection
1807 data for the fastest route for given ID.
1809 * Implemented INVITE command on client and server. The command
1810 were re-defined in the SILC Protocol Specification and the
1811 implementation now complies with the specification.
1813 * Implemented PING command on client and server.
1815 * Implemented NAMES command on client and server. The server side
1816 supports currently only normal server not router server yet.
1817 Some changes to NAMES definition in SILC protocol specification.
1819 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Implemented LEAVE command on client and server.
1823 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1824 again. This change was made to the protocol as well. Server
1825 should not violate the protocol specification anymore.
1827 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1830 was tested. SOCKS4 was not but should work anyway.
