1 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Redefined ciphers for the SILC protocol. Added some new ciphers
4 and defined the key lengths for the algorithms. Changed the
5 code accordingly. The default key length is now 256 bits.
7 * Fixed SKE key distribution function silc_ske_process_key_material
8 when the key length is more than 128 bits. The default key
9 length in SILC is now 256 bits.
11 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
12 to indicate unsupported algorithm.
14 * Renamed rijndael.c to aes.c and all functions as well.
16 * Fixed a long standing channel key setting bug in client library.
17 Weird that it has never surfaced before.
19 * Fixed bug in channel deletion. If the entire channel is removed
20 then it must also delete the references of the channel entry
21 from the client's channel list as the client's channel entry and
22 the channel's client entry share same memory.
24 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
26 * Implemented CONNECT and SHUTDOWN commands in the client.
28 * Implemented CLOSE command to the client.
30 * Added the function silc_idlist_find_server_by_name into the
31 files silcd/idlist.[ch].
33 Added the function silc_idlist_find_server_by_conn into the
34 files silcd/idlist.[ch].
36 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
38 * DIE command was renamed to SHUTDOWN. Updated the both code
41 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
42 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
44 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
47 * Added function silc_server_create_connection function to create
48 connection to remote router. My server implementation actually
49 does not allow router to connect to normal server (it expects
50 that normal server always initiates the connection to the router)
51 so the CONNECT command is only good for connecting to another
54 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
56 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
57 or some other client was kicked from the channel.
59 Implemented the handling of the notify type to both client
62 Implemented silc_server_send_notify_kicked to send the KICKED
63 notify. It is used to send it to the server's primary router.
65 * Implemented the KICK command into server and client.
67 * Added `query' argument to the silc_idlist_get_client function
68 to indicate whether to query the client from server or not if
71 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
72 to indicate that the client is not channel founder.
76 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
78 * Removed the rng context from SilcPacketContext structure and
79 changed that the packet routine uses the Global RNG API.
81 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Added support for quit message that client can "leave" on the
84 channel when it quits the SILC. It is ditributed inside the
85 SILC_NOTIFY_TYPE_SIGNOFF notify type.
87 Added silc_server_free_client_data that will take the
88 signoff message as argument.
90 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
92 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
94 * Updated parts of the protocol specification to keep it up
97 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
99 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
100 payloads in one packet.
102 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
103 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
104 use now the new List flag.
106 * Also deprecated the following packet types: REPLACE_ID,
107 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
109 * Added list support for Notify packet in server.
111 * Added silc_server_send_notify_channel_change to send the
112 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
113 the silc_server_send_replace_id.
115 * Added silc_server_send_notify_nick_change to send the
116 NICK_CHANGE notify type. Deprecates the function
117 silc_server_send_replace_id.
119 * Added silc_server_send_notify_join to send the JOIN notify type.
120 Deprecates the function silc_server_send_new_channel_user.
122 * Added silc_server_send_notify_leave to send LEAVE notify type.
123 Deprecates the function silc_server_send_remove_channel_user.
125 * Added silc_server_send_notify_cmode and
126 silc_server_send_notify_cumode to send CMODE and CUMODE notify
127 types. Deprecates the silc_server_send_set_mode function.
129 * Added SERVER_SIGNOFF notify type to indicate that server has
130 quit. This means that all clients on the channel from that
131 server will drop. This can be also used when netsplit happens.
133 Deprecated REMOVE_ID packet type since it is not needed anymore
136 Added silc_server_send_notify_server_signoff to send the
137 SERVER_SIGNOFF notify type. Deprecates the function
138 silc_server_send_remove_id.
140 Added also silc_server_send_notify_signoff to send the
143 * Employed the PKCS #1. It is the mandatory way to do RSA in the
144 SILC protocol from this day on. Changed the protocol
145 specification as well.
147 * Added silc_server_send_notify_topic_set to send TOPIC_SET
148 notify type. It is used between routers to notify about
149 topic changes on a channel.
151 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
154 * Partly updated the protocol specification to comply with the
155 changes now made. It is still though a bit outdated.
157 * The JOIN notify type now takes one extra argument <Channel ID>.
158 The packet used to be destined to the channel but now the
159 JOIN type may be sent as list thus it is impossible to
160 destine it to any specific channel. By adding this argument
161 it is again possible.
163 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Added CREDITS file. The CHANGES and CREDITS file will appear
166 in the distribution as well.
168 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
170 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
171 types in the server's silcd/packet_receive.c.
173 * Implemented CMODE and CUMODE to work in router environment.
175 * Fixed minor encoding and decoding buglet from the
176 lib/silccore/silcmode.c.
178 * Fixed buffer overflow from lib/silcclient/command.c in USERS
181 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
183 * Changed all SilcConfigServer* and silc_config_server* to
184 SilcServerConfig* and silc_server_config*, respectively.
187 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Associated the ID (client or server ID) to the Authentication
190 Payload to avoid any possibility of forging. Updated the
191 protocol specification and the code accordingly.
193 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * The RSA key length is now save to the RsaKey context in the
196 key generation process in lib/silccrypt/rsa.c. The key length
197 is now used to figure out the maximum size of the block allowed
198 to be encrypted/signed.
200 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
201 is equivalent to the silc_mp_mp2bin but does not allocate any
204 * Changed silc_mp_mp2bin API to take length argument. If it is
205 non-zero then the buffer is allocated that large. If zero, then
206 the size is approximated using silc_mp_sizeinbase, which however
209 * Created Global RNG API which is global RNG that application can
210 initialize. After initializing, any routine anywhere in the
211 code (including library) can use RNG without allocating a new
212 RNG object. This was done to allow this sort of use of the
213 RNG in code that has no chance to allocate RNG object. All
214 applications currently allocate this and many routines in the
215 library use this. Affected file lib/silccrypt/silcrng.[ch].
217 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
218 it to use the Global RNG API.
220 * Defined Authentication Payload into protocol specification that
221 is used during SILC session to authenticate entities. It is
222 used for example by client to authenticate itself to the server
223 to obtain server operator privileges.
225 Implemented this payload into the lib/silccore/silcauth.[ch].
226 Implemented also routines for public key based authentication
227 as the new protocol specification dictates.
229 Moved definitions of different authentication methods from
230 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
232 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
233 silc_pkcs_verify and silc_pkcs_sign_with_hash and
234 silc_pkcs_verify_with_hash functions into the file
235 lib/silccrypt/silcpkcs.[ch].
237 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
239 * The client entry's userinfo pointer must be always valid.
240 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
241 will fail since it requires the userinfo. Now, the userinfo
242 is allocated as "" if actual userinfo does not exist. Actually,
243 it must exist and it is totally Ok to drop client connections
244 that does not announce the userinfo. However, we will make
245 this workaround for now.
247 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
248 to return the remote port by socket.
250 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
252 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
253 SILC_SERVER_PENDING_EXEC and added an new macro
254 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
255 data or when error occurs while processing the pending command.
257 Added new argument `destructor' into silc_server_command_pending
258 and to the SilcServerCommandPending object. This destructor is
259 now called after calling the pending callback or if error occurs
260 immediately. If error occurs the actual pending callback won't
261 be called at all - only the destructor. The destructor may be
262 NULL if destructor is not needed.
264 All this applies for client library code as well. Similar
265 changes were made there as well for the pending commands.
267 In the client, the application must now allocate the
268 SilcClientCommandContext with the silc_client_command_alloc
271 * Added reference counter to the SilcServerCommandContext. Added
272 function silc_server_command_alloc and silc_server_command_dup
275 Same type of functions added to the client library for the same
278 * Removed the cmd_ident from IDListData away since it is now
279 global for all connections. It is the command identifier used
280 in command sending and with pending commands. The affected file
283 * Added reference counter to the SilcSocketConnection objecet to
284 indicate the usage count of the object. The object won't be
285 freed untill the reference counter hits zero. Currently only
286 server uses this, and client ignores it. The client must be
287 set to use this too later. The affected files are
288 lib/silccore/silcsockconn.[ch]. Added also the function
289 silc_socket_dup to increase the reference counter.
291 This was mainly added because it is possible that the socket
292 is removed underneath of pending command or other async
293 operation. Now it won't be free'd and proper DISCONNECTING
294 flags, etc. can be set to avoid sending data to connection that
295 is not valid anymore.
297 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
298 the connection. After that it sets SILC_SET_DISCONNECTED.
299 It is, however, possible that the socket data is not still freed.
300 The silc_server_packet_process now checks that data is not
301 read or written to connection that is DISCONNECTED. The socket
302 get's freed when the reference counter hits zero.
304 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * Changed the client operation API: channel_message operation's
307 `sender' is now the client entry of the sender, not the nickname
308 and the `channel' is the channel entry, not the channel name.
310 In the private_message operation the `sender' is now also the
311 client entry of the sender not the nickname.
313 Affected file is lib/silcclient/ops.h and all applications
314 using the client operations.
316 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Moved the calling of ops->connect() from connect_to_server_final
319 into receive_new_id functin since that is the point when the
320 client is actually allowed to send traffic to network. The
321 affected file is lib/silcclient/client.c.
323 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
325 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
326 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
327 (if needs broadcasting) instead of broadcasting the packets one
328 by one which would make a burst in the network traffic.
330 * Added `broadcast' argument to the functions in silcd/server.[ch]
331 silc_server_create_new_channel[_with_id] to indicate whether
332 to send New Channel packet to primary router.
334 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Added new function into the silcd/server.[ch] files:
337 silc_server_create_new_channel_with_id to create new channel with
338 already existing Channel ID.
340 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
341 lib/silccore/silcpacket.h. This packet is used t send list of
342 Set Mode payloads inside one packet. Server uses this to set
343 the modes for the channels and clients on those channels, that it
344 announced to the router when it connected to it. The protocol
345 specification has been updated accordingly.
347 * The silc_server_new_channel did not handle the packet coming
348 from normal server as it normally does not send that. However,
349 when it announces its channels it does send it. Implemented
350 the support for that.
352 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
353 into the file lib/silccore/id.h.
355 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
357 * Fixed memory leaks in the functions silc_idlist_del_client,
358 silc_idlist_del_channel and silc_idlist_del_server in the file
359 silcd/idlist.c. All of those leaked like a sieve.
361 * Fixed some small memory leaks in the client's function
362 silc_client_notify_by_server.
364 * Added functions into silcd/server.c: silc_server_announce_clients,
365 silc_server_announce_channels and silc_server_announce_server.
366 These functions are used by normal and router server to announce
367 to its primary router about clients, channels and servers (when
368 router) that we own. This is done after we've connected to the
371 These functions effectively implements the following packet types:
372 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
373 and SILC_PACKET_NEW_ID_LIST.
375 * Added new functions into the silcd/packet_receive.[ch]:
376 silc_server_new_id_list, silc_server_new_channel_list and
377 silc_server_new_channel_user_list to handle the incoming
378 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
380 * Added support of changing Channel ID in the function
381 silc_server_replace_id. If the server that announces a channel
382 to the router already exists in the router (with same name but
383 with different Channel ID), router is responsible to send
384 Replace ID packet to the server and force the server to change
385 the Channel ID to the one router has.
387 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
388 client that the Channel ID has been changed by the router. The
389 normal server sends this to the client. Client must start using
390 the new Channel ID as the channel's ID.
392 Implemented handling of this new type into lib/silcclient/client.c
393 into the function silc_client_notify_by_server.
395 * Added new function silc_idlist_replace_channel_id into the files
396 silcd/idlist.[ch] to replace the Channel ID.
398 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Call silc_server_command_identify_check always when processing
401 the IDENTIFY command in silcd/command.c
403 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
406 send keepalive packets. The packet can be sent by clients,
409 Added function silc_socket_set_heartbeat into the file
410 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
411 If not set, the heartbeat is not performed. The actual
412 heartbeat is implemented in the low level socket connection
413 library. However, application is responsible of actually
416 Added silc_server_send_heartbeat to send the actual heartbeat
417 packet into silcd/packet_send.[ch]. Server now performs
418 keepalive with all connections.
420 * Added silc_task_get_first function into lib/silcutil/silctask.c
421 to return the timeout task with shortest timeout. There was a bug
422 in task unregistration that caused problems. TODO has been
423 updated to include that task system must be rewritten.
425 * The client library will now resolve the client information when
426 receiving JOIN notify from server for client that we know but
427 have incomplete information.
429 * Rewrote parts of silc_server_remove_from_channels and
430 silc_server_remove_from_one_channel as they did not remove the
431 channel in some circumstances even though they should've.
433 * Encryption problem encountered in server:
435 The LEAVE command used to send the Channel Key packet to the
436 router immediately after generating it. However, the code
437 had earlier sent Remove Channel user packet but not immediately,
438 ie. it was put to queue. The order of packets in the router
439 was that Channel Key packet was first and Remove Channel User
440 packet was second, even though they were encrypted in the
441 reverse order. For this reason, MAC check failed. Now, this
442 is fixed by not sending the Channel Key packet immediately but
443 putting it to queue. However, this is more fundamental problem:
444 packets that are in queue should actually not be encrypted
445 because packets that are sent immediately gets encrypted
446 actually with wrong IV (and thus MAC check fails). So, packets
447 that are in queue should be encrypted when they are sent to
448 the wire and not when they put to the queue.
450 However, the problem is that the current system has not been
451 designed to work that way. Instead, the packet is encrypted
452 as soon as possible and left to the queue. The queue is then
453 just purged into wire. There won't be any fixes for this
454 any time soon. So, the current semantic for packet sending
457 o If you send packet to remote host and do not force the send
458 (the packet will be in queue) then all subsequent packets to the
459 same remote host must also be put to the queue. Only after the
460 queue has been purged is it safe again to force the packet
463 o If you send all packets immediately then it safe to send
464 any of subsequent packets through the queue, however, after
465 the first packet is put to queue then any subsequent packets
466 must also be put to the queue.
468 Follow these rules and everything works fine.
470 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Added new function silc_server_remove_clients_by_server to
473 remove all client entries from ID list when the server connection
474 is lost. In this case it is also important to invalidate all
475 client entires as they hold the invalid server entry. This
476 fixes fatal bug when server has lost connection and will reconnect
479 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Made some sanity checks to silc_server_daemonise like to check
482 whether the requested user and group actually exists.
484 * Added sanity check to SKE's silc_ske_responder_finish to check
485 that the public and private key actually is valid.
487 * Invalidate the client's nickname when receiving Replace ID
488 packet and the Client ID is being replaced. This means that the
489 server will query the nickname if someone needs it (client)
492 * Sort the ID Cache in client library when the ID Cache data
493 has changed (needs sorting).
495 * Do not allow for SILC client to create several connections to
496 several servers. The client does not support windows right now
497 and generating multiple connections causes weird behaviour.
499 Irssi-silc client does support windows and can handle several
500 connections without problems, see: www.irssi.org and SILC plugin.
502 * Fixed some places where client was added to the IDList. The
503 rule of thumb is following (in order to get everything right):
504 If the client is directly connected local client then the
505 `connection' argument must be set and `router' argument must be
506 NULL to silc_idlist_add_client function. If the client is not
507 directly connected client then the `router' argument must
508 bet set and the `connection' argument must be NULL to the
509 silc_idlist_add_client function.
511 * The funtion silc_server_packet_send_local_channel actually did
512 not check whether the client was locally connected or not. It
513 does that now. Fixed a bug related to LEAVE command.
515 * Fixed Remove Channel User payload parsing bug in server's
516 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
518 * The server's silc_server_save_channel_key now checks also the
519 global ID list for the channel as it might not be in the local
520 list. Fixed a bug related to LEAVE command.
522 * Is this the end of the [<unknown>] buglet that has been lurking
523 around for a long time? A little for loop fix in server's
524 silc_server_command_whois_parse that is used by both IDENTIFY
525 and WHOIS command. At least, this was a clear bug and a cause
526 of one type of [<unknown>] buglet.
528 * WHOIS and IDENTIFY commands call the function
529 silc_server_command_[whois/identify]_check function even if
530 we are not router server.
532 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
534 * Added --with-gmp configuration option. If set the GMP
535 is always compiled in the SILC source tree. If not set then
536 it is checked whether the system has the GMP3 installed. If
537 it has then the GMP won't be compiled (the system's headers
538 and library is used), if it doesn't have it then the GMP is
539 compiled in the SILC source tree.
541 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Changed RSA private exponent generation to what PKCS #1
544 suggests. We try to find the smallest possible d by doing
545 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
546 not security fix but optimization.
548 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
550 * Added new config entry [Identity] to fork the server and run
551 it as specific user and group. A patch from Bostik.
553 * Imported Dotconf configuration library into lib/dotconf.
554 This will be used to create the SILC configuration files later.
555 It will appear in the distsribution after this commit.
557 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * A big code auditing weekend happening. Auditing code for
560 obvious mistakes, bugs and errors. Also, removing any code
563 Removed files for being obsolete:
565 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
566 inline in the file lib/silcutil/silcbuffer.h)
568 o lib/silcutil/silcbufutil.c (the header has inline versions)
570 Changed code to fix possible error conditions:
572 o The buffer formatting routines now check that the destination
573 buffer really has enough space to add the data. This applies for
574 both buffer formatting and unformatting
575 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
576 unformatting was changed to accomodate following rules:
577 XXX_*STRING_ALLOC will allocate space for the data into the pointer
578 sent to the function while XXX_*STRING will not allocate or copy
579 the data into the buffer. Instead it sets the pointer from the
580 buffer into the pointer sent as argument (XXX_*STRING used to
581 require that the pointer must be allocated already). This change
582 makes this whole thing a bit more consistent and more optimized
583 (note that the data returned in the unformatting with XXX_*STRING
584 must not be freed now). The routines return now -1 on error.
586 o Tried to find all code that use buffer_format and buffer_unformat
587 and added return value checking to prevent formatting and
588 especially unformatting errors and possible subsequent fatal
591 o Changed ske->x and ske->KEY to mallocated pointers in
592 lib/silcske/silcske.h. Fixed possible data and memory leak.
594 o Added return value checking to all *_parse* functions. Fixed
595 many memory leaks as well.
597 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
598 so that buffer overflows would not happen. All code now also
599 checks the return value as it can fail.
601 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Added reconnection support to server if the normal server looses
604 its connection to the router (for example if router is rebooted).
605 The server performs normal reconnection strategy implemented
606 to the server. Affected file silcd/server.c.
608 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Added new packet type SILC_PACKET_SET_MODE that is used to
611 distribute the information about changed modes (for clients,
612 channels and clients channel modes) to all routers in the
613 network. Updated the protocol specification accordingly.
615 Added functions into silcd/packet_send.c and
616 silcd/packet_receive.c: silc_server_send_set_mode,
617 silc_server_set_mode.
619 Added new files silcmode.[ch] into lib/silccore that implements
620 the encoding and decoding of Set Mode Payload. Added new type
621 SilcSetModePayload. Moved the definitions of different modes
622 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
624 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
626 * Oops, a little mistake in server's connection authentication
627 protocol. The protocol is not ended with FAILURE but with
628 SUCCESS if the authentication is Ok. :) Affected file is
631 * Implemented NICK_CHANGE notify handling in server in the file
632 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
633 the local clients on the channel. After the changing nickname
634 in router environment snhould work and the [<unknown>] nickname
635 should appear no more.
637 The silc_server_replace_id function that receives the Replace ID
638 payload now sends the NICK_CHANGE notify type also in the file
639 silcd/packet_receive.c
641 * Changed WHOIS and IDENTIFY command to support the maximum amount
642 of arguments defined in protocol specs (3328 arguments). This
643 fixed a bug that caused problems when there were more than three
646 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
648 * Added extra parameter, command identifier, to the
649 silc_client_send_command so that explicit command identifier
652 Changed that ID list routines uses specific command identifier
653 when sending WHOIS/IDENTIFY requests to the server so that they
654 can be identified when the reply comes back.
656 Affected files lib/silcclient/command.[ch],
657 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
659 * Added `sender' argument to silc_server_packet_send_to_channel
660 to indicaet the sender who originally sent the packet to us
661 that we are now re-sending. Ignored if NULL. Affected file
662 silcd/packet_send.[ch].
664 * Added some server statistics support in silcd/server_internal.h
665 SilcServerStatistics structure and around the server code. Also
666 send some nice statistics information when client is connecting
669 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Fixed channel ID decoding in server's JOIN command reply in
672 silcd/command_reply.c
674 * Fixed braodcasting of replace ID payload to not to send it if
675 we are standalone server in silcd/packet_receive.c.
677 * Fixed all channel message sending routines to not to send
678 packets to clients that has router set, since they are routed
679 separately in the same function earlier. Affects file
680 silcd/packet_send.c and all channel packet sending functions.
682 * In USERS reply, res_argv[i] are not allocated, the table
683 is allocated. Thus changed that free the table, not its
686 * In server's whois_check and identify_check if the client is
687 locally connected do not send any WHOIS commands - they are not
690 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Fixed some minor bugs in client when sending WHOIS command. The
693 arguments was in wrong order.
695 * Removed statis function add_to_channel from server in
696 silcd/command.c that was previously used with the joining but
699 * Tested USERS command in router environment successfully with two
700 routers, two servers and two clients.
702 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Reorganized the USERS command and command reply in client library
705 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
706 When the command is given by user we register a pending command
707 callback that will reprocess the command after the reply has been
708 received from the server. When reprocessing the packet we then
709 display the information. Thus, the USERS information is displayed
710 now in the command callback instead of in the command reply
711 callback. The processing of the command is same as previously
712 when server has sent the command reply in the JOINing process.
714 * Added to USERS command in silcd/command_reply.c to join the client,
715 we didn't use to know about, to the channel after we've created
716 a client entry for it. Also, for clienet we did know already still
717 check whether it is on the channel or not and add it if not.
719 * Removed silc_server_command_join_notify as the function and its
722 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Changed the client's pending command handling to the same as the
725 server's pending command handling. It is also now possible to
726 execute command reply functions from other command reply
727 function as the function callbacks for commands and command
728 replies are one and same. The pending commands are not static
729 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
730 in client connection context. Thus, pending commands are server
731 connection specific as it is convenient.
733 Changed the function silc_client_command_pending and
734 silc_client_command_pending_del and added new function
735 silc_client_command_pending_check. Removed the
736 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
739 * Added cmd_ident, current command identifier, to the client
740 connection context in lib/silcclient/client.h to keep track on
741 command identifiers used in command sending. Client's command reply
742 function handling now supports the mandatory command identifiers.
744 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
745 funtions in client to fully support pending command callbacks.
747 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
748 as one of the arguments to the application in the command reply
751 * NOTE: The FORWARDED flag is depracated. It used to be depracated
752 before first releasing SILC but came back. Now it is removed again
753 and should come back nomore. The FORWARDED flag was used only
754 by the JOINing procedure by forwarding the command packet to router.
755 Now, the JOINing procedure has been changed to more generic (due
756 to various router environment issues) and FORWARDED is not needed
757 anymore for anything. The protocol specification is yet to be
760 Now, removed silc_server_packet_forward from server and the flag
761 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
763 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Renamed NAMES command to USERS command. The NAMES was named that
766 due to historical reasons. Now it is renamed. Also, rewrote
767 parts of the USERS command. The nickname list is not sent anymore
768 by the server. Only Client ID and mode lists are sent in the USERS
769 command. Changed this also to the protocol specification.
771 The client now resolves the names and stuff after it receives
772 the USERS list from the server when joining to the channel.
774 * WHOIS and IDENTIFY commands has been changed to support multiple
775 Client ID's per command. One can now search for multiple users
776 in the network by sending only one WHOIS or IDENTIFY command.
777 Changed the code and the protocol specifications.
779 * Removed silc_server_command_identify_parse and changed that IDENTIFY
780 uses silc_server_command_whois_parse to parse the request. */
782 * If normal server, do not parse the WHOIS and IDENTIFY requests
783 before sending it to the router. Saves some time.
785 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Fixed JOIN command on client library. Wrong number of arguments
788 used to crash the client.
790 * Added silc_server_channel_has_global function to check whether
791 channel has global users or not.
793 * Added silc_server_channel_has_local function to check whether channel
794 has locally connected clients on the channel.
796 * The silc_server_remove_from_one_channel now checks whether the
797 channel has global users or not after given client was removed from
798 the channel. It also checks whether the channel has local clients
799 on the channel anymore. If it does not have then the channel entry
800 is removed as it is not needed anymore.
802 * The silc_server_notify now checks on JOIN notify whether the joining
803 client is one of locally connected or global. If it is global then
804 the channel has now global users on the channel and that is marked
805 to the channel entry. Also, it now saves the global client to
806 global list who is joining and JOINs it to the channel. This is
807 for normal server, that is.
809 Changed silc_server_send_notify_on_channel,
810 silc_server_packet_relay_to_channel and
811 silc_server_packet_send_to_channel check if we are normal server
812 and client has router set (ie. global client) do not send the
813 message to that client, as it is already routed to our router.
815 * Implemented LEAVE notify type handling in silc_server_notify
818 * Tested LEAVE command in router environment successfully. Tested
819 with two routers, two servers and two clients.
823 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
825 * Implemented SIGNOFF notify type handling in silc_server_notify
828 * silc_server_remove_id now removes the client entry from all channels
829 it has joined and thusly sends SIGNOFF notify type.
831 * Rewrote the NAMES list generation in server by removing two excess
832 loops. The lists are created now inside one loop.
834 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * silc_server_remove_channel_user checks now also global list
837 for channel and client.
839 * silc_server_new_channel_user checks now both local and global
840 list for channel and client. Fixed a bug in client id decoding.
841 Used to decode wrong buffer.
843 * silc_server_channel_message checks now both local and global
844 list for channel entry.
846 * Tested channel joining (hence JOIN) in router environment
847 successfully. Tested with two routers, two servers and two
850 * Tested channel message sending in router environment successfully.
852 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Added silc_server_save_channel_key into server.[ch] to save the
855 received channel key in Channel Key payload processing. It is
856 also used in JOIN command reply handling.
858 Equivalent function silc_client_save_channel_key added into
859 client.[ch] into client library.
861 * Changed JOIN command reply to send information whether the channel
862 was created or not (is existing already) and the channel key
863 payload. Changed protocol specs accordingly.
865 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
866 the request was sent by ID and not by nickname. Crashed on
869 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
872 now correctly save the received data.
874 * silc_server_free_sock_user_data now notifies routers in the
875 network about entities leaving the network.
877 At the same time implemented functions silc_server_remove_id
878 and silc_server_send_remove_id to receive and send REMOVE_ID
879 packets. The packet is used to notify routers in the network
880 about leaving entities. The ID removed will become invalid in
883 * Added function silc_idlist_del_server into server. Removes and
884 free's server entry from ID list.
886 * silc_server_private_message function now checks, if we are router,
887 that the destination ID really is valid ID, naturally.
889 * In router when NEW_ID packet is received (for new client) the
890 hash of the Client ID is saved in the ID Cache but the
891 client->nickname is set to NULL, instead of putting the hash
894 IDENTIFY command now also checks that client->nickname must be
895 valid. If it is not if will request the data from the server who
896 owns the client. Added new function
897 silc_server_command_identify_check.
899 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
900 to set the command to already allocated Command Payload.
902 * Tested private message sending in router environment with two
903 routers, two servers and two clients. Fixed minor bugs and now
906 * Fixed segfault from client's NAMES command. Used to crash if
909 * Forwarded packets must not be routed even if it is not destined
910 to the receiver. Changed server code comply with this.
912 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Added `require_reverse_mapping' boolean value to ServerParams
915 structure. If TRUE (not default) the server will require that
916 the connecting host has fully qualified domain name.
918 If the reverse mapping is not required and hostname could not be
919 found the IP address is used as hostname.
921 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Implemented version string checking to both client and server.
924 The check is incomplete currently due to the abnormal version
925 strings used in development version of SILC.
927 * Changed all command functions in server to use the new
930 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Changed char *data to unsigned char *data in ID Cache system to
933 support binary data as ID Cache data. Changed code to support
934 binary data in lib/silccore/idcache.c.
936 * Renamed silc_server_packet_relay_command_reply to
937 silc_server_command_reply as it is normal packet receiving
938 function. Rewrote the function to accept command replys for
939 servers and not only for clients.
941 * Mark remote router always as registered server if we are connecting
942 to it. Otherwise, commands sent by the router to us are ignored.
944 * All ID List find routines now returns the ID Cache Entry pointer
945 as well if requested.
947 * WHOIS command works now in router environment, tested with two
948 routers, two servers and two clients.
950 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
951 in router environment (as it is almost equivalent to WHOIS) but
952 hasn't been tested thoroughly. Added new functions:
954 silc_server_command_identify_parse
955 silc_server_command_identify_send_reply
956 silc_server_command_identify_from_client
957 silc_server_command_identify_from_server
959 * Disabled route cache adding because adding two different ID's with
960 same IP replaces the old cache entry thus giving wrong route.
961 The entry->router->connection is always the fastest route anyway
962 so route cache may not be needed. Of course, new routes maybe
963 established after receiving the ID when the entry->router->connection
964 might not be anymore the most optimal.
966 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Add route cache for received ID for fast routing.
970 * Added silc_server_packet_route to route received packet on router
971 that is not destined to us.
973 * Renamed silc_server_get_route to silc_server_route_get.
975 * Added id_string and id_string_len fields into SilcServer to
976 include encoded ServerID for fast comparing without excess
977 encoding of the ID's.
979 * Cleaned up WHOIS command on server side. Added following static
982 silc_server_command_whois_parse
983 silc_server_command_whois_check
984 silc_server_command_whois_send_reply
985 silc_server_command_whois_from_client
986 silc_server_command_whois_from_server
988 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
989 arguments in command replies. All command functions should be
990 updated to use this macro.
992 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Minor typo fixes on command reply handling on server.
996 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Added silc_server_command_add_to_channel internal routine to add
999 the client to the channel after router has created the channel and
1000 sent command reply to the server.
1002 * Added generic silc_server_send_command to send any command from
1005 * Use static buffer with ID rendering instead of duplicating data.
1007 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Fixed a channel user mode bug when joining to a channel server gave
1010 everybody channel founder rights, oops.
1012 * We mark ourselves as the router of the incoming server connection
1013 if we are router ourselves. This way we can check in some packet
1014 sending functions whether it is locally connected server. For
1015 incoming router connections we put NULL.
1017 * For router sending packets locally means now always sending the
1018 packet cell wide; to local clients and local servers. For normal
1019 server sending packet locally means sending it to only local
1022 * Fixed the JOIN command to really work in router environment. If the
1023 channel is created it is always created by the router. Router is
1024 also responsible of making the initial joining to the channel,
1025 sending JOIN notify to the sending server and distributing
1026 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1027 does not exist server doesn't do anything else but forward the
1028 command to the router which performs everything.
1030 * Added silc_server_send_channel_key function to send the Channel Key
1033 * Added silc_server_create_channel_key to create new channel key. The
1034 channel key is now re-generated everytime someone joins or leaves
1035 a channel, as protocol dictates. Note: channel->key_len is the
1038 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1040 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1041 packet_receive.[ch] to separate packet sending and receiving
1042 routines. The server.[ch] now includes everything else including
1043 actual packet processing (writing and reading data) and other
1046 Renamed silc_server_private_message_send_internal to
1047 silc_server_send_private_message. The routine is still though
1048 used only to relay private messages as server does not send
1049 private messages itself.
1051 Renamed silc_server_new_channel to silc_server_create_new_channel
1052 and added new function sicl_server_new_channel that handles the
1053 incoming New Channel packet. Added also new sending function
1054 silc_server_send_new_channel to send New Channel Payload.
1056 * Added new function silc_server_notify to process incoming notify
1057 packet to the server/router. Server may then relay the notify
1058 to clients if needed.
1060 * Added new function silc_server_new_channel_user to process incoming
1061 New Channel User packet. Router will redistribute the packet and
1062 send JOIN notify to its local clients and locally connected servers
1063 if needed. Normal server will send JOIN notify to its local client
1064 on same channel when received this packet. Added also corresponding
1065 sending function silc_server_send_new_channel_user to sent the
1068 * Added boolean route argument to send_notif_to_channel and
1069 packet_send_to_channel functions to attempt to route the packet
1070 if it is TRUE and send only locally if it is FALSE.
1072 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * silc_server_replace_id now broadcasts the received replace ID
1075 packet if it is not broadcast packet already. The router must
1076 broadcast to inform other routers about changed ID.
1078 * Added backpointer to server's router into SilcServer context in
1079 silcd/server_internal.h.
1081 * Fixed silc_server_packet_broadcast to send correct broadcast
1084 * The channel key is now distributed to the local client as soon
1085 as it is received from the router (in router environment) so that
1086 no other packet may be sent for the channel until client has
1089 * silc_server_remove_channel_user now broadcasts the received
1090 Remove Channel User packet if it is not broadcast packet already.
1091 The router must broadcast to inform other routers about removed
1094 * Added users field into SilcPacketContext that is a reference count
1095 of the context. One can increase the reference count by calling
1096 silc_packet_context_dup which is now changed to just increase the
1097 reference count instead of duplicating the data. The reference
1098 count is decresed by calling silc_packet_context_free that will
1099 free the data after the reference count hits zero.
1101 For now on the packet context and everything allocated into it
1102 (including the raw packet from network) must be freed by calling
1103 the new silc_packet_context_free function. Added also new function
1104 silc_packet_context_alloc that must be used now to allocate the
1105 context. This also means that if a routine is asynchronous from
1106 silc_[client/server]_packet_parse_type the packet context must
1107 be duplicated by calling silc_packet_context_dup. Otherwise it
1108 gets free'd after silc_[client/server]_packet_parse_type returns.
1109 Also, one must remember that if packet is duplicated then its
1110 reference count must be decresed by calling the free function as
1111 many times as it was duplicated.
1113 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1114 from both client and server.
1116 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * Made joining to a channel working in router environment.
1120 * Cleaned up JOIN command on server side and create function
1121 silc_server_command_join_channel internal routine to make the
1124 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Changed silc_command_pending list to SilcDList. Also, added
1127 `ident' field to SilcServerCommandPending structure to identify
1128 the reply and to call correct callback.
1130 Added silc_server_command_pending_check function to replace the
1131 corresnponding macro. The silc_command_pending list is not
1134 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1135 to set identifier to previously allocated Command Payload. It
1136 is used to set identifier for command when resending Command
1139 * Added silc_command_payload_encode_payload to encode Command
1140 Payload buffer from SilcCommandPayload structure.
1142 * Added silc_argument_payload_encode_payload to encode Argument
1143 payload buffer from SilcArgumentPayload structure.
1145 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * Changed WHOIS command to support router connection on server side.
1148 The whois request is always sent to router unless the server is
1149 standalone server. After server has received the reply from the
1150 router will it send the reply to the client.
1152 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1153 broadcast received broadcast packet. The function is used only
1154 by router. The broadcast packet is always sent to the router's
1157 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1158 render given ID to printable string, for log files for example.
1160 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Made basic router to router connections working. At least they
1163 can now connect to each other but nothing really works the way
1164 they are supposed - yet.
1166 * Added new initiator token to RouterConnection configuration
1167 file in silcd/serverconfig.[ch]. It is used to tell whether we
1168 are the initiator to the remote router or whether we'll expect
1169 the other end to connect.
1171 * Moved registering of listener task to silc_server_init, hence
1172 the server starts listenning as soon as it is run, even if it
1173 does not have connections to other routers. Let's see how well
1176 * Changed default connection retry timeouts for more suitable in
1179 * Removed cipher and such arguments from silc_idlist_add_client
1180 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1181 Added new function silc_idlist_add_data to add the keys and stuff
1184 * Added SilcIDListData structure and added it to SilcClientEntry
1185 and SilcServerEntry as their first field in the structure. This
1186 way we can explicitly cast the ID entries to the SilcIDListData
1187 structure and get common data for the entries. In past, we had
1188 to first check what type of connection it is and then cast it to
1189 correct ID entry type. Now, we can directly cast the opaque
1190 pointer to the SilcIDListData (no matter what ID entry it actually
1191 is) and get the data needed.
1193 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1195 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1196 in some circumstances even if threre were timeout tasks, though not
1197 IO tasks, but tasks anyway. Now fixed.
1199 * Defined SilcServerConnection structure to hold connection specific
1200 stuff about directly connected servers and routers. The definition
1201 is currently in silcd/server_internal.h. I thought about having
1202 a bit more important role fro this struct but for now it is used
1203 only when connecting to other server (or router actually).
1205 * Added connecting retry support in server when connecting to
1206 router(s). The retry feature implement exponential backoff
1207 algorithm. Also, added SilcServerParams structure to hold default
1208 parameters for server. For now, it include these retry settings
1209 and are hard coded. After server is moded to be as Silc Server
1210 Library this structure will be more important.
1212 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1214 * Changed client librarys channel->clients table to SilcList and
1215 changed code accordingly.
1217 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Changed client's channel table to SilcList and changed code
1220 accordingly. Also changed SilcChannelClientEntry to include back-
1221 pointer to the channel so that client entry can use that structure
1222 as list as well and we have fast cross-reference to the channel.
1223 This change dramatically decreased the complexity of channel
1224 handling with client entry and vice versa (removed one extra
1225 loop when searching for channel entry from many functions).
1227 * Changed server->sim from table to SilcDList and changed code
1230 * NAMES command can now be used from user interface. It will show
1231 the user list on the channel, neatly.
1233 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1234 Code now saves realname of the user if it becomes available.
1236 * Renamed configure.in to configure.in.pre and made ./prepare
1237 script to automatically add correct version string to
1238 configure.in which it creates from configure.in.pre.
1240 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * NAMES command reply now shows users mode with the nickname when
1245 * Moved silc_client_ch[u]mode[_char] functions from
1246 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1247 place sucks, they are utility functions and should be in some
1250 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1252 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1255 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Added TRQ (efficient deque and list library) into lib/trq. This is
1260 a very good list library that is currently used in the SILC. Defined
1261 SilcList API over the library because I didn't like the API very
1262 much. See lib/trq/silclist.h for the API and examples of how to
1263 use the API. Fixed various places in the code to use the new
1264 SilcList API. The SilcList is meant for lists that has a structure
1265 already defined as a list. It is not suitable to add just some
1266 context to the list (in TRQ, the context is the list actually).
1268 So, I defined SilcDList that can be used for the purpose where
1269 predefined list structure does not exit. This can be used as
1270 such list. Now some context just can be added to the SilcDList.
1271 Currently this list is not used in the SILC just yet, though there
1272 are a lot places where this can replace dynamically allocated
1273 tables and I will fix these places, later, to use SilcDList.
1274 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1275 and use TRQ internally).
1277 Also fixed some annoying warning messages that the original TRQ
1278 code generated. Also minor changes to TRQ's Makefile.in.
1280 * Added support for querying by Client ID to both WHOIS and
1281 IDENTIFY commands into server, as required by the protocol.
1283 * Removed method function pointers from SilcBuffer structure. They
1284 weren't used to anything and just increased the context size for
1285 no good reason. This change also made silc_buffer_alloc and
1286 silc_buffer_free functions inline functions.
1288 * Disabled command flooding detection support until it's fixed so
1289 that it accepts commands in but does not execute them more than once
1292 * Added silc_net_localhost(), to return local hostname, into
1293 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1294 that must be initialized before calling silc_client_init.
1296 * Added new function: silc_server_send_notify_on_channels to send
1297 notify messages to all channels client has joined. It is assured
1298 that the message is sent only once per client.
1300 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1301 lib/silcutil/silcutil.[ch] as silc_format function. The new
1302 function is generic and is used by server as well, not only by
1303 the logging routines.
1305 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1306 the provided version string was not acceptable. Added new function:
1307 silc_ske_check_version into lib/silcske/silcske.h. The function
1308 must be implemented by the application (client or server) and it
1309 does not reside in the SKE library. The function checks the version
1310 string remote end sent.
1312 * Added back pointers (to opaque context and to SilcSocketConnection)
1313 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1315 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1316 duplicate packet context structure.
1318 * Changed `notify' client operation to send same arguments as client
1319 receives from server except for ID's. ID's are mapped to correct
1320 ID entry and that is returned. Also, if channel entry is not sent
1321 by server but the notify is for channel the channel entry is sent
1322 to application (otherwise application doesn't know that it is for
1323 channel (library gets it from packet's Destination ID)).
1325 * Added silc_client_remove_from_channels into client library to
1326 remove a client from all channels it has joined to. Used when
1327 received SIGNOFF notify from server. Added also new function
1328 silc_client_replace_from_channels to replace old ID entry with
1329 new ID entry on all channels. Used when received NICK_CHANGE
1332 * Fixed ID Cache list handling in silc_idlist_get_client in
1333 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1334 to get (or query) client by ID.
1336 * Updated TODO list.
1338 * Added connection authentication status message defined by the
1339 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1340 support for these into the code in client and server side.
1342 * Added generic function silc_client_send_command to send any command
1343 with variable argument list. Application should use this function
1344 to send commands if the command functions provided by the library
1345 does not suite for the application's user interface needs.
1347 * Added new `failure' client operation. Application is notified about
1348 received failure packet if client is executing a protocol. In this
1349 case the protocol's execution has failed.
1351 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1352 is required by the protocol.
1354 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1355 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1358 * Added status flag to SilcSKE object to indicate realtime status
1359 of the SKE protocol.
1361 * Application receives now exactly same command reply arguments as
1362 the library receives from server. However, if ID is received the
1363 corresponding ID entry is returned to the application (eg. Client
1364 ID is mapped to correct SilcClientEntry entry and that is returned).
1365 Changed command_reply client operation due to this change.
1367 * Changed all ID's in commands and in command replys as ID Payloads.
1368 Change affected both client and server side codes.
1370 All ID's sent in SILC network (with execption of ID's in SILC
1371 Packet header) are sent in ID Payload to support variable length
1374 * Server now notifies nick changes and notifies all clients on
1375 the channels about the new nickname (about the new Client ID,
1378 * Implemented CMODE command to change channel modes. Supports all
1379 channel modes defined by the protocol specs except ban and invite
1380 lists. (Also, private channel key mode is supported but support for
1381 setting private channel key in client is missing, thus, this mode
1382 has no effect on client side (except that server requires that the
1383 client uses private channel key and normal channel traffic does not
1386 Also, invite mode works per se, but INVITE command does not work
1387 yet correctly, so you can set channel as invite only channel but
1388 inviting clients to the channel does not work (it is yet to be
1389 thought what's the best way to do it).
1391 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1392 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1393 Implemented CUMODE command to change user's mode on the channel.
1394 Supports all modes defined by the protocol specs.
1396 * Added NAMES command reply to return users modes on the channel.
1398 * Removed unnecessary and slow ciphers from lib/silccrypt.
1400 * Set SO_KEEPALIVE option to connection sockets by default.
1402 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1404 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1405 redefined the Notify Payload into protocol specs.
1407 * Added silc_id_payload_parse_id to get ID directly from raw
1410 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1413 accept searching by Client ID as well.
1415 * Added support for LEAVE and SIGNOFF notify types in client library.
1417 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1418 to parse ID Payload from raw data.
1420 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1422 * Added flags parameter into silc_ske_assemble_security_properties
1423 function in lib/silcske/silcske.[ch].
1425 * Changed notify client operation to fit better for notify messages
1426 sent by server. The notify payload received from server is now
1427 passed to the application (after parsing it to SilcNotifyPayload).
1428 It is application's responsibility to retrieve the arguments
1429 from the payload and show the message the way it wants. The message
1430 sent by server is implementation specific.
1432 * Changed public keys to comply with the protocol specification.
1433 Old public keys are not supported anymore and are not compatible.
1435 * Removed nickname from Channel Payload as the latest draft removed
1436 it. The client must resolve the nickname from the NAMES command
1437 reply received when it joined the channel.
1439 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1441 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Fixed some errors in protocol specification drafts.
1445 * Created lib/silccore/silcnotify.c to implement Notify Payload
1446 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1447 generic payloads described by protocol specifications. The file
1448 includes implementations for ID Payload and Argument Payload.
1450 * Changed Command Payload implementation to use the new Argument
1451 Payload. Changed command_xxxx_payload to command_payload_xxxx
1452 to comply with SILC coding conventions.
1454 * Added suppport for Argument Payload handling in Notify Payload
1455 implementation as protocol requires it. Added the new support
1456 into server and client lib as well.
1458 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Added support for multiple nicknames on same channel. [n] is
1461 added locally to the nickname if there are more than one same
1462 nicknames on the channel.
1464 * Server now sends all nicknames that matched WHOIS request.
1465 Client also shows the list received from server.
1467 * Added TOPIC command to client side. User can now set and show
1468 current topic on channel.
1470 * Added MOTD command to client and server. Also, server sends the
1471 motd when client connects to the server.
1473 * Changed version strings to comply ISO 8601.
1475 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * Fixed protocol error handling in client library. It should now
1478 cope even if the SKE fails for some reason.
1480 * Made new protocol specification drafts for submitting to IETF.
1482 * Implemented TOPIC command to server in silcd/command.c.
1484 * Added two new notify types into lib/silccore/silcnotify.h:
1485 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1486 notify nickname change and topic setting/change on a channel.
1488 * API change of command_reply operation in client library. The
1489 application gets now the status type received from server as well.
1491 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1493 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1495 * Cras fixed and optimized the packet handling even further and
1496 it should work now. Minor change to the prototype of function
1497 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1499 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Added new function into lib/silcutil/silcschedule.[ch]:
1502 silc_schedule_with_fd to select() a specified fd. The function
1503 returns after timeout expires or data arrives or goes. The
1504 function is used by packet routines to wait that all data is
1505 received from network.
1507 * Fixed data reading from network in lib/silccore/silcpacket.c.
1508 The code now assures that all data is read from the fd and then
1509 continues packet processing. This was a bug fix since the code
1510 used to drop some data in some circumstances.
1512 * Added new function into lib/silcclient/client.[ch]:
1513 silc_client_start_key_exchange to start key exchange after
1514 connection has been established to server. The code internally
1515 now uses this funtion but its main purpose was to provide it
1516 for applications that perform their own connecting. After
1517 application has created a connection it merely calls this
1518 function to start the key exchange between client and server.
1519 The library takes care of everything else after that.
1521 Updated also lib/silcclient/README to explain the usage of
1524 * Do not send to application information that connection has
1525 been established. Application gets notified it by connect
1528 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Applied cras's patch to add silc_schedule_one function. The
1531 function runs scheduler once and returns.
1533 * Fixed the scheduler after cras messed it up. The timeout
1534 handling works now as it's supposed to work.
1536 * Added into lib/silccore/ silcnotify.h to include notify
1537 message types support. Changed silc_server_send_notify*
1538 functions, in server.[ch], to support those new notify types.
1539 Added the support for the notify types into client library,
1540 as well. Added new notify client operation into ops.h in
1543 * Changed silc_server_packet_send_to_channel to send normal
1544 packets instead of just channel message packets. The function
1545 is now used to send the notify packets to channels. It is not
1546 used to send channel message packets anymore, as server never
1549 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1550 va_arg()s as it seems to require it nowadays. I guess, if SILC
1551 is compiled with older va_arg() the new code should work anyway.
1553 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Splitted core library. Core library (lib/silccore) includes
1556 now only SILC protocol specific core (and common) components.
1557 Created new utility library (lib/silcutil) that includes more
1558 generic purpose stuff. The stuff for util library was taken
1559 from the old core library. This was minor and easy split.
1561 * Created SILC Client Library (lib/silcclient) that includes
1562 implementation of the SILC client without user interface. This
1563 was major move from silc/ directory. The code has been changed
1564 so that it is transparent towards the user interface. The
1565 silc/ directory includes now the same user interface as before
1566 and it uses the new client library. Read lib/silcclient/README.
1567 Basicly, the client library performs everything else related
1568 to SILC except user interface handling. Also, configuration
1569 files are considered to be part of user interface and library
1570 does not handle them.
1572 This change also changed a lot of structures, function naming etc.
1573 Most important change was that SilcClientWindow object was
1574 renamed to SilcClientConnection in the client library. Created
1575 also new file lib/silcclient/ops.h. Also added new files
1576 silc/local_command.[ch] and silc/client_ops.[ch].
1578 All these changes were made to make it easier for user interface
1579 designers to create what ever user interface for the SILC client
1582 It is also expected that the server will be moved to lib
1583 directory as well and SILC Server Library will be created;
1584 sometimes in the future.
1586 * Removed Local commands from lib/silccore/silccommand.h as
1587 they are application specific and new client library does not
1588 handle any of those anymore.
1590 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1591 old client implementation in silc/.
1593 * Added support for callback functions in SILC_LOG_* macros.
1594 Application can now set its own callbacks that will be called
1595 instead of using the default functions that will always print
1596 the debug messages to stderr (or stdout). Also, debugging can
1597 now be disabled by setting silc_debug to FALSE and re-enabled by
1598 setting it to TRUE. Note, that logging will still work even
1599 if debugging is disabled.
1601 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1602 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1603 silc_log_reset_debug_callbacks.
1605 * To enable debugging in silc client one must give now -d
1606 option on command line.
1608 * Changed silc_schedule_init to automatically allocate task queues
1609 if they are not allocated before calling it.
1611 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Added GMP 3.1 into math library.
1615 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1617 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1618 a channel in SILC network. The packet is used by servers and
1619 routers to notify other routers that user has left a channel.
1620 This little feature was missing until now. Added the feature
1621 to protocol specification as well.
1623 Added functions: silc_server_send_remove_channel_user and
1624 silc_server_remove_channel_user into server.[ch].
1626 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1627 lib/silccore/silcpacket.h. However, they are not implemented
1630 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1632 * Fixed joining to a channel and sending channel messages
1633 between server and router. The channel message sending should
1634 now work inside a cell.
1636 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Fixed the private message sending between server and router.
1639 The private message sending should now work inside a cell.
1641 * Added silc_server_replace_id into server.[ch] to replace
1642 existing ID in the SILC network.
1644 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1645 and silc_idlist_replace_server_id into idlist.[ch] in server.
1647 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Fixed the server to server connections. Server can again now
1650 connect to router. Router to router connections probably does
1653 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Added dynamic protocol registering support. Now protocols can
1656 registered and unregistered on the fly. Patch by cras.
1658 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * Added lib/contrib directory to hold routines that some platforms
1661 don't have but are needed by SILC.
1663 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1664 into lin/contrib to provide getopt() and getopt_long() for
1665 those who don't have it.
1667 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Added AWAY command to client. When away message is set and
1670 client receives a private message packet the client automatically
1671 replies to the sender with the away message.
1673 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1674 bug seemed to be the cause of recent problems when compiling
1677 * Added version detection support to SKE protocol specification
1678 and added the new changes to the SKE implementation as well.
1679 There were other minor changes in the SKE protocol as well.
1681 Many changes in lib/silcske/silcske.[ch] and in
1682 lib/silcske/payload.[ch].
1684 * Added ^U functionality, clear input line. Patch from cras.
1686 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1688 * Mainly small bugfixes on core library. Fixed some debugging
1689 logging and buffer overflow in silclog.c.
1691 * Updated config.sub and config.guess on the distribution tree.
1693 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1695 * Added command lagging support in server. Client may execute
1696 commands now only once in two seconds.
1698 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Optimized packet reception. MAC computation and checking is now
1701 also more optimized. A lot previously duplicated code is now
1702 used as generic by both client and server.
1704 * Fixed key pair generation in clientutil.c
1706 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * Added into lib/silccore/silcbufutil.[ch] new function;
1709 silc_buffer_realloc.
1711 * Moved generic packet sending/encryption functions to
1712 lib/silccore/silcpacket.[ch] from client and server. Some
1713 rewriting of the functions.
1715 * Moved all generic packet reception/decryption functions to
1716 lib/silccore/silcpacket.[ch] from client and server. The
1717 packet processing is now much cleaner in both client and server.
1718 These were major changes in both client and server.
1720 * Created many common functions in server to do packet sending.
1721 Previously code were duplicated a lot, this has been removed
1724 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Rewrote major parts of the ID cache system. Don't know
1727 whether it is better now or not but at least the API is more
1730 * Major rewrite on ID cache stuff on client because of the ID
1731 cache API changes. Added idlist.c to client.
1733 * Also major rewrite on ID cache stuff on server as well.
1734 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1735 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1736 in hand, instead they are all put into the ID cache system now.
1737 All server_idlist_* routines uses ID cache now instead of
1738 traversing its own lists (those lists does not exist anymore).
1739 SilcIDList though still exists. Also, SilcXXXEntry's are
1742 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1744 * Finally made the SKE implementation compliant to the protocol
1745 specification. All mp integers are now binary encoded as
1746 opposed being HEX encoded.
1748 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1751 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1752 functions: silc_[encode/decode]_pem. Also added function
1753 silc_encode_pem_file to PEM encode with newlines ('\n') for
1756 * SILC public keys are now encoded either PEM or binary. Same
1757 option is for private keys as well. By default private keys
1758 are binary encoded and public keys PEM encoded. Silly HEX
1759 encoding were removed.
1761 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1762 function to create fingerprints.
1764 * Fixed a bug in SHA1; does not change the original data anymore.
1766 * Partly implemented INFO command on client and server side.
1767 Fixed CLEAR command. Changes to SERVER command; show current
1768 server(s) when giving command without arguments. Added
1769 VERSION command to client.
1771 * Added check to server that unregistered connections cannot
1772 execute commands (unless it is specificly allowed).
1774 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Fixed screen refresh.
1778 * Fixed channel joining bug from client. On some circumstances
1779 client tried to join to a channel it had already joined.
1781 * Added public key verification process into client's protocol.c.
1782 The client now verifies the public key from user and saves
1783 it into ~./silc/serverkeys/ directory.
1785 Added into: clientutil.[ch]: silc_client_verify_server_key.
1787 * Changed SKE protocol's silc_ske_initiator_finish function
1788 to accept callback function that verifies the received public
1789 key. Removed old silc_ske_verify_public_key function.
1791 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1794 silc_pkcs_private_key[_data]_set.
1796 * Made the password and public authentication more cleaner in
1797 server's protocol.c.
1799 * Removed historic and obsolete protocol `channel_auth' from
1800 both client and server.
1802 * Removed wrong way of sending command status messages from
1803 server to client in server's command.c. The old way violated
1804 protocol specification.
1806 Changes to silccore/silccommand.[ch]: removed
1807 silc_command_encode_status_payload -> not needed anymore,
1808 changed silc_command_encode_payload_va to accept extra
1809 argument on variable argument list. The argument type must
1810 now be provided to the function. Also, added new function:
1811 silc_command_encode_reply_payload_va which is same as
1812 normal command_encode_payload_va except command status type
1813 is provided as extra argument.
1815 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1817 * Added ~./silc directory handling. The directory includes the
1818 public and private keys for the client.
1820 Added silc_client_check_silc_dir, silc_client_create_identifier
1821 and silc_client_load_keys.
1823 * Implemented SILC protocol compliant public key. Added public
1824 and private key saving to and loading from files.
1826 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1827 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1828 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1829 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1830 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1832 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1833 silc_pkcs_load_[public/private]_key.
1835 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Added silc_server_get_route (route.[ch]) to get connection
1838 data for the fastest route for given ID.
1840 * Implemented INVITE command on client and server. The command
1841 were re-defined in the SILC Protocol Specification and the
1842 implementation now complies with the specification.
1844 * Implemented PING command on client and server.
1846 * Implemented NAMES command on client and server. The server side
1847 supports currently only normal server not router server yet.
1848 Some changes to NAMES definition in SILC protocol specification.
1850 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Implemented LEAVE command on client and server.
1854 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1855 again. This change was made to the protocol as well. Server
1856 should not violate the protocol specification anymore.
1858 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1860 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1861 was tested. SOCKS4 was not but should work anyway.
