1 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Removed lib/silcclient/ops.h file.
5 Redefined parts of the SILC Client Library API. Created new
6 file silcapi.h that deprecates the ops.h file and defines the
7 published Client Library API. Defined also private message key
8 API and channel private key API into the file.
10 This is the file that the application must include from the
11 SILC Client Library. Other files need not be included by
12 the application anymore.
14 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
17 is used by clients to request key negotiation between another
18 client in the SILC network. If the negotiation is started it
19 is performed using the SKE protocol. The result of the
20 negotiation, the secret key material, can be used for example
21 as private message key.
23 Implemented the Key Agreement payload into the files
24 lib/silccore/silauth.[ch].
26 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Redefined ciphers for the SILC protocol. Added some new ciphers
29 and defined the key lengths for the algorithms. Changed the
30 code accordingly. The default key length is now 256 bits.
32 * Fixed SKE key distribution function silc_ske_process_key_material
33 when the key length is more than 128 bits. The default key
34 length in SILC is now 256 bits.
36 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
37 to indicate unsupported algorithm.
39 * Renamed rijndael.c to aes.c and all functions as well.
41 * Fixed a long standing channel key setting bug in client library.
42 Weird that it has never surfaced before.
44 * Fixed bug in channel deletion. If the entire channel is removed
45 then it must also delete the references of the channel entry
46 from the client's channel list as the client's channel entry and
47 the channel's client entry share same memory.
49 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Implemented CONNECT and SHUTDOWN commands in the client.
53 * Implemented CLOSE command to the client.
55 * Added the function silc_idlist_find_server_by_name into the
56 files silcd/idlist.[ch].
58 Added the function silc_idlist_find_server_by_conn into the
59 files silcd/idlist.[ch].
61 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
63 * DIE command was renamed to SHUTDOWN. Updated the both code
66 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
67 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
69 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
72 * Added function silc_server_create_connection function to create
73 connection to remote router. My server implementation actually
74 does not allow router to connect to normal server (it expects
75 that normal server always initiates the connection to the router)
76 so the CONNECT command is only good for connecting to another
79 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
82 or some other client was kicked from the channel.
84 Implemented the handling of the notify type to both client
87 Implemented silc_server_send_notify_kicked to send the KICKED
88 notify. It is used to send it to the server's primary router.
90 * Implemented the KICK command into server and client.
92 * Added `query' argument to the silc_idlist_get_client function
93 to indicate whether to query the client from server or not if
96 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
97 to indicate that the client is not channel founder.
101 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
103 * Removed the rng context from SilcPacketContext structure and
104 changed that the packet routine uses the Global RNG API.
106 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Added support for quit message that client can "leave" on the
109 channel when it quits the SILC. It is ditributed inside the
110 SILC_NOTIFY_TYPE_SIGNOFF notify type.
112 Added silc_server_free_client_data that will take the
113 signoff message as argument.
115 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
117 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
119 * Updated parts of the protocol specification to keep it up
122 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
125 payloads in one packet.
127 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
128 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
129 use now the new List flag.
131 * Also deprecated the following packet types: REPLACE_ID,
132 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
134 * Added list support for Notify packet in server.
136 * Added silc_server_send_notify_channel_change to send the
137 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
138 the silc_server_send_replace_id.
140 * Added silc_server_send_notify_nick_change to send the
141 NICK_CHANGE notify type. Deprecates the function
142 silc_server_send_replace_id.
144 * Added silc_server_send_notify_join to send the JOIN notify type.
145 Deprecates the function silc_server_send_new_channel_user.
147 * Added silc_server_send_notify_leave to send LEAVE notify type.
148 Deprecates the function silc_server_send_remove_channel_user.
150 * Added silc_server_send_notify_cmode and
151 silc_server_send_notify_cumode to send CMODE and CUMODE notify
152 types. Deprecates the silc_server_send_set_mode function.
154 * Added SERVER_SIGNOFF notify type to indicate that server has
155 quit. This means that all clients on the channel from that
156 server will drop. This can be also used when netsplit happens.
158 Deprecated REMOVE_ID packet type since it is not needed anymore
161 Added silc_server_send_notify_server_signoff to send the
162 SERVER_SIGNOFF notify type. Deprecates the function
163 silc_server_send_remove_id.
165 Added also silc_server_send_notify_signoff to send the
168 * Employed the PKCS #1. It is the mandatory way to do RSA in the
169 SILC protocol from this day on. Changed the protocol
170 specification as well.
172 * Added silc_server_send_notify_topic_set to send TOPIC_SET
173 notify type. It is used between routers to notify about
174 topic changes on a channel.
176 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
179 * Partly updated the protocol specification to comply with the
180 changes now made. It is still though a bit outdated.
182 * The JOIN notify type now takes one extra argument <Channel ID>.
183 The packet used to be destined to the channel but now the
184 JOIN type may be sent as list thus it is impossible to
185 destine it to any specific channel. By adding this argument
186 it is again possible.
188 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
190 * Added CREDITS file. The CHANGES and CREDITS file will appear
191 in the distribution as well.
193 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
196 types in the server's silcd/packet_receive.c.
198 * Implemented CMODE and CUMODE to work in router environment.
200 * Fixed minor encoding and decoding buglet from the
201 lib/silccore/silcmode.c.
203 * Fixed buffer overflow from lib/silcclient/command.c in USERS
206 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
208 * Changed all SilcConfigServer* and silc_config_server* to
209 SilcServerConfig* and silc_server_config*, respectively.
212 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Associated the ID (client or server ID) to the Authentication
215 Payload to avoid any possibility of forging. Updated the
216 protocol specification and the code accordingly.
218 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
220 * The RSA key length is now save to the RsaKey context in the
221 key generation process in lib/silccrypt/rsa.c. The key length
222 is now used to figure out the maximum size of the block allowed
223 to be encrypted/signed.
225 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
226 is equivalent to the silc_mp_mp2bin but does not allocate any
229 * Changed silc_mp_mp2bin API to take length argument. If it is
230 non-zero then the buffer is allocated that large. If zero, then
231 the size is approximated using silc_mp_sizeinbase, which however
234 * Created Global RNG API which is global RNG that application can
235 initialize. After initializing, any routine anywhere in the
236 code (including library) can use RNG without allocating a new
237 RNG object. This was done to allow this sort of use of the
238 RNG in code that has no chance to allocate RNG object. All
239 applications currently allocate this and many routines in the
240 library use this. Affected file lib/silccrypt/silcrng.[ch].
242 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
243 it to use the Global RNG API.
245 * Defined Authentication Payload into protocol specification that
246 is used during SILC session to authenticate entities. It is
247 used for example by client to authenticate itself to the server
248 to obtain server operator privileges.
250 Implemented this payload into the lib/silccore/silcauth.[ch].
251 Implemented also routines for public key based authentication
252 as the new protocol specification dictates.
254 Moved definitions of different authentication methods from
255 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
257 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
258 silc_pkcs_verify and silc_pkcs_sign_with_hash and
259 silc_pkcs_verify_with_hash functions into the file
260 lib/silccrypt/silcpkcs.[ch].
262 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * The client entry's userinfo pointer must be always valid.
265 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
266 will fail since it requires the userinfo. Now, the userinfo
267 is allocated as "" if actual userinfo does not exist. Actually,
268 it must exist and it is totally Ok to drop client connections
269 that does not announce the userinfo. However, we will make
270 this workaround for now.
272 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
273 to return the remote port by socket.
275 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
278 SILC_SERVER_PENDING_EXEC and added an new macro
279 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
280 data or when error occurs while processing the pending command.
282 Added new argument `destructor' into silc_server_command_pending
283 and to the SilcServerCommandPending object. This destructor is
284 now called after calling the pending callback or if error occurs
285 immediately. If error occurs the actual pending callback won't
286 be called at all - only the destructor. The destructor may be
287 NULL if destructor is not needed.
289 All this applies for client library code as well. Similar
290 changes were made there as well for the pending commands.
292 In the client, the application must now allocate the
293 SilcClientCommandContext with the silc_client_command_alloc
296 * Added reference counter to the SilcServerCommandContext. Added
297 function silc_server_command_alloc and silc_server_command_dup
300 Same type of functions added to the client library for the same
303 * Removed the cmd_ident from IDListData away since it is now
304 global for all connections. It is the command identifier used
305 in command sending and with pending commands. The affected file
308 * Added reference counter to the SilcSocketConnection objecet to
309 indicate the usage count of the object. The object won't be
310 freed untill the reference counter hits zero. Currently only
311 server uses this, and client ignores it. The client must be
312 set to use this too later. The affected files are
313 lib/silccore/silcsockconn.[ch]. Added also the function
314 silc_socket_dup to increase the reference counter.
316 This was mainly added because it is possible that the socket
317 is removed underneath of pending command or other async
318 operation. Now it won't be free'd and proper DISCONNECTING
319 flags, etc. can be set to avoid sending data to connection that
320 is not valid anymore.
322 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
323 the connection. After that it sets SILC_SET_DISCONNECTED.
324 It is, however, possible that the socket data is not still freed.
325 The silc_server_packet_process now checks that data is not
326 read or written to connection that is DISCONNECTED. The socket
327 get's freed when the reference counter hits zero.
329 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
331 * Changed the client operation API: channel_message operation's
332 `sender' is now the client entry of the sender, not the nickname
333 and the `channel' is the channel entry, not the channel name.
335 In the private_message operation the `sender' is now also the
336 client entry of the sender not the nickname.
338 Affected file is lib/silcclient/ops.h and all applications
339 using the client operations.
341 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Moved the calling of ops->connect() from connect_to_server_final
344 into receive_new_id functin since that is the point when the
345 client is actually allowed to send traffic to network. The
346 affected file is lib/silcclient/client.c.
348 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
350 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
351 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
352 (if needs broadcasting) instead of broadcasting the packets one
353 by one which would make a burst in the network traffic.
355 * Added `broadcast' argument to the functions in silcd/server.[ch]
356 silc_server_create_new_channel[_with_id] to indicate whether
357 to send New Channel packet to primary router.
359 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Added new function into the silcd/server.[ch] files:
362 silc_server_create_new_channel_with_id to create new channel with
363 already existing Channel ID.
365 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
366 lib/silccore/silcpacket.h. This packet is used t send list of
367 Set Mode payloads inside one packet. Server uses this to set
368 the modes for the channels and clients on those channels, that it
369 announced to the router when it connected to it. The protocol
370 specification has been updated accordingly.
372 * The silc_server_new_channel did not handle the packet coming
373 from normal server as it normally does not send that. However,
374 when it announces its channels it does send it. Implemented
375 the support for that.
377 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
378 into the file lib/silccore/id.h.
380 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
382 * Fixed memory leaks in the functions silc_idlist_del_client,
383 silc_idlist_del_channel and silc_idlist_del_server in the file
384 silcd/idlist.c. All of those leaked like a sieve.
386 * Fixed some small memory leaks in the client's function
387 silc_client_notify_by_server.
389 * Added functions into silcd/server.c: silc_server_announce_clients,
390 silc_server_announce_channels and silc_server_announce_server.
391 These functions are used by normal and router server to announce
392 to its primary router about clients, channels and servers (when
393 router) that we own. This is done after we've connected to the
396 These functions effectively implements the following packet types:
397 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
398 and SILC_PACKET_NEW_ID_LIST.
400 * Added new functions into the silcd/packet_receive.[ch]:
401 silc_server_new_id_list, silc_server_new_channel_list and
402 silc_server_new_channel_user_list to handle the incoming
403 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
405 * Added support of changing Channel ID in the function
406 silc_server_replace_id. If the server that announces a channel
407 to the router already exists in the router (with same name but
408 with different Channel ID), router is responsible to send
409 Replace ID packet to the server and force the server to change
410 the Channel ID to the one router has.
412 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
413 client that the Channel ID has been changed by the router. The
414 normal server sends this to the client. Client must start using
415 the new Channel ID as the channel's ID.
417 Implemented handling of this new type into lib/silcclient/client.c
418 into the function silc_client_notify_by_server.
420 * Added new function silc_idlist_replace_channel_id into the files
421 silcd/idlist.[ch] to replace the Channel ID.
423 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Call silc_server_command_identify_check always when processing
426 the IDENTIFY command in silcd/command.c
428 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
431 send keepalive packets. The packet can be sent by clients,
434 Added function silc_socket_set_heartbeat into the file
435 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
436 If not set, the heartbeat is not performed. The actual
437 heartbeat is implemented in the low level socket connection
438 library. However, application is responsible of actually
441 Added silc_server_send_heartbeat to send the actual heartbeat
442 packet into silcd/packet_send.[ch]. Server now performs
443 keepalive with all connections.
445 * Added silc_task_get_first function into lib/silcutil/silctask.c
446 to return the timeout task with shortest timeout. There was a bug
447 in task unregistration that caused problems. TODO has been
448 updated to include that task system must be rewritten.
450 * The client library will now resolve the client information when
451 receiving JOIN notify from server for client that we know but
452 have incomplete information.
454 * Rewrote parts of silc_server_remove_from_channels and
455 silc_server_remove_from_one_channel as they did not remove the
456 channel in some circumstances even though they should've.
458 * Encryption problem encountered in server:
460 The LEAVE command used to send the Channel Key packet to the
461 router immediately after generating it. However, the code
462 had earlier sent Remove Channel user packet but not immediately,
463 ie. it was put to queue. The order of packets in the router
464 was that Channel Key packet was first and Remove Channel User
465 packet was second, even though they were encrypted in the
466 reverse order. For this reason, MAC check failed. Now, this
467 is fixed by not sending the Channel Key packet immediately but
468 putting it to queue. However, this is more fundamental problem:
469 packets that are in queue should actually not be encrypted
470 because packets that are sent immediately gets encrypted
471 actually with wrong IV (and thus MAC check fails). So, packets
472 that are in queue should be encrypted when they are sent to
473 the wire and not when they put to the queue.
475 However, the problem is that the current system has not been
476 designed to work that way. Instead, the packet is encrypted
477 as soon as possible and left to the queue. The queue is then
478 just purged into wire. There won't be any fixes for this
479 any time soon. So, the current semantic for packet sending
482 o If you send packet to remote host and do not force the send
483 (the packet will be in queue) then all subsequent packets to the
484 same remote host must also be put to the queue. Only after the
485 queue has been purged is it safe again to force the packet
488 o If you send all packets immediately then it safe to send
489 any of subsequent packets through the queue, however, after
490 the first packet is put to queue then any subsequent packets
491 must also be put to the queue.
493 Follow these rules and everything works fine.
495 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
497 * Added new function silc_server_remove_clients_by_server to
498 remove all client entries from ID list when the server connection
499 is lost. In this case it is also important to invalidate all
500 client entires as they hold the invalid server entry. This
501 fixes fatal bug when server has lost connection and will reconnect
504 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Made some sanity checks to silc_server_daemonise like to check
507 whether the requested user and group actually exists.
509 * Added sanity check to SKE's silc_ske_responder_finish to check
510 that the public and private key actually is valid.
512 * Invalidate the client's nickname when receiving Replace ID
513 packet and the Client ID is being replaced. This means that the
514 server will query the nickname if someone needs it (client)
517 * Sort the ID Cache in client library when the ID Cache data
518 has changed (needs sorting).
520 * Do not allow for SILC client to create several connections to
521 several servers. The client does not support windows right now
522 and generating multiple connections causes weird behaviour.
524 Irssi-silc client does support windows and can handle several
525 connections without problems, see: www.irssi.org and SILC plugin.
527 * Fixed some places where client was added to the IDList. The
528 rule of thumb is following (in order to get everything right):
529 If the client is directly connected local client then the
530 `connection' argument must be set and `router' argument must be
531 NULL to silc_idlist_add_client function. If the client is not
532 directly connected client then the `router' argument must
533 bet set and the `connection' argument must be NULL to the
534 silc_idlist_add_client function.
536 * The funtion silc_server_packet_send_local_channel actually did
537 not check whether the client was locally connected or not. It
538 does that now. Fixed a bug related to LEAVE command.
540 * Fixed Remove Channel User payload parsing bug in server's
541 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
543 * The server's silc_server_save_channel_key now checks also the
544 global ID list for the channel as it might not be in the local
545 list. Fixed a bug related to LEAVE command.
547 * Is this the end of the [<unknown>] buglet that has been lurking
548 around for a long time? A little for loop fix in server's
549 silc_server_command_whois_parse that is used by both IDENTIFY
550 and WHOIS command. At least, this was a clear bug and a cause
551 of one type of [<unknown>] buglet.
553 * WHOIS and IDENTIFY commands call the function
554 silc_server_command_[whois/identify]_check function even if
555 we are not router server.
557 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Added --with-gmp configuration option. If set the GMP
560 is always compiled in the SILC source tree. If not set then
561 it is checked whether the system has the GMP3 installed. If
562 it has then the GMP won't be compiled (the system's headers
563 and library is used), if it doesn't have it then the GMP is
564 compiled in the SILC source tree.
566 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * Changed RSA private exponent generation to what PKCS #1
569 suggests. We try to find the smallest possible d by doing
570 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
571 not security fix but optimization.
573 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * Added new config entry [Identity] to fork the server and run
576 it as specific user and group. A patch from Bostik.
578 * Imported Dotconf configuration library into lib/dotconf.
579 This will be used to create the SILC configuration files later.
580 It will appear in the distsribution after this commit.
582 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
584 * A big code auditing weekend happening. Auditing code for
585 obvious mistakes, bugs and errors. Also, removing any code
588 Removed files for being obsolete:
590 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
591 inline in the file lib/silcutil/silcbuffer.h)
593 o lib/silcutil/silcbufutil.c (the header has inline versions)
595 Changed code to fix possible error conditions:
597 o The buffer formatting routines now check that the destination
598 buffer really has enough space to add the data. This applies for
599 both buffer formatting and unformatting
600 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
601 unformatting was changed to accomodate following rules:
602 XXX_*STRING_ALLOC will allocate space for the data into the pointer
603 sent to the function while XXX_*STRING will not allocate or copy
604 the data into the buffer. Instead it sets the pointer from the
605 buffer into the pointer sent as argument (XXX_*STRING used to
606 require that the pointer must be allocated already). This change
607 makes this whole thing a bit more consistent and more optimized
608 (note that the data returned in the unformatting with XXX_*STRING
609 must not be freed now). The routines return now -1 on error.
611 o Tried to find all code that use buffer_format and buffer_unformat
612 and added return value checking to prevent formatting and
613 especially unformatting errors and possible subsequent fatal
616 o Changed ske->x and ske->KEY to mallocated pointers in
617 lib/silcske/silcske.h. Fixed possible data and memory leak.
619 o Added return value checking to all *_parse* functions. Fixed
620 many memory leaks as well.
622 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
623 so that buffer overflows would not happen. All code now also
624 checks the return value as it can fail.
626 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Added reconnection support to server if the normal server looses
629 its connection to the router (for example if router is rebooted).
630 The server performs normal reconnection strategy implemented
631 to the server. Affected file silcd/server.c.
633 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
635 * Added new packet type SILC_PACKET_SET_MODE that is used to
636 distribute the information about changed modes (for clients,
637 channels and clients channel modes) to all routers in the
638 network. Updated the protocol specification accordingly.
640 Added functions into silcd/packet_send.c and
641 silcd/packet_receive.c: silc_server_send_set_mode,
642 silc_server_set_mode.
644 Added new files silcmode.[ch] into lib/silccore that implements
645 the encoding and decoding of Set Mode Payload. Added new type
646 SilcSetModePayload. Moved the definitions of different modes
647 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
649 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Oops, a little mistake in server's connection authentication
652 protocol. The protocol is not ended with FAILURE but with
653 SUCCESS if the authentication is Ok. :) Affected file is
656 * Implemented NICK_CHANGE notify handling in server in the file
657 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
658 the local clients on the channel. After the changing nickname
659 in router environment snhould work and the [<unknown>] nickname
660 should appear no more.
662 The silc_server_replace_id function that receives the Replace ID
663 payload now sends the NICK_CHANGE notify type also in the file
664 silcd/packet_receive.c
666 * Changed WHOIS and IDENTIFY command to support the maximum amount
667 of arguments defined in protocol specs (3328 arguments). This
668 fixed a bug that caused problems when there were more than three
671 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Added extra parameter, command identifier, to the
674 silc_client_send_command so that explicit command identifier
677 Changed that ID list routines uses specific command identifier
678 when sending WHOIS/IDENTIFY requests to the server so that they
679 can be identified when the reply comes back.
681 Affected files lib/silcclient/command.[ch],
682 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
684 * Added `sender' argument to silc_server_packet_send_to_channel
685 to indicaet the sender who originally sent the packet to us
686 that we are now re-sending. Ignored if NULL. Affected file
687 silcd/packet_send.[ch].
689 * Added some server statistics support in silcd/server_internal.h
690 SilcServerStatistics structure and around the server code. Also
691 send some nice statistics information when client is connecting
694 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Fixed channel ID decoding in server's JOIN command reply in
697 silcd/command_reply.c
699 * Fixed braodcasting of replace ID payload to not to send it if
700 we are standalone server in silcd/packet_receive.c.
702 * Fixed all channel message sending routines to not to send
703 packets to clients that has router set, since they are routed
704 separately in the same function earlier. Affects file
705 silcd/packet_send.c and all channel packet sending functions.
707 * In USERS reply, res_argv[i] are not allocated, the table
708 is allocated. Thus changed that free the table, not its
711 * In server's whois_check and identify_check if the client is
712 locally connected do not send any WHOIS commands - they are not
715 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Fixed some minor bugs in client when sending WHOIS command. The
718 arguments was in wrong order.
720 * Removed statis function add_to_channel from server in
721 silcd/command.c that was previously used with the joining but
724 * Tested USERS command in router environment successfully with two
725 routers, two servers and two clients.
727 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
729 * Reorganized the USERS command and command reply in client library
730 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
731 When the command is given by user we register a pending command
732 callback that will reprocess the command after the reply has been
733 received from the server. When reprocessing the packet we then
734 display the information. Thus, the USERS information is displayed
735 now in the command callback instead of in the command reply
736 callback. The processing of the command is same as previously
737 when server has sent the command reply in the JOINing process.
739 * Added to USERS command in silcd/command_reply.c to join the client,
740 we didn't use to know about, to the channel after we've created
741 a client entry for it. Also, for clienet we did know already still
742 check whether it is on the channel or not and add it if not.
744 * Removed silc_server_command_join_notify as the function and its
747 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Changed the client's pending command handling to the same as the
750 server's pending command handling. It is also now possible to
751 execute command reply functions from other command reply
752 function as the function callbacks for commands and command
753 replies are one and same. The pending commands are not static
754 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
755 in client connection context. Thus, pending commands are server
756 connection specific as it is convenient.
758 Changed the function silc_client_command_pending and
759 silc_client_command_pending_del and added new function
760 silc_client_command_pending_check. Removed the
761 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
764 * Added cmd_ident, current command identifier, to the client
765 connection context in lib/silcclient/client.h to keep track on
766 command identifiers used in command sending. Client's command reply
767 function handling now supports the mandatory command identifiers.
769 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
770 funtions in client to fully support pending command callbacks.
772 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
773 as one of the arguments to the application in the command reply
776 * NOTE: The FORWARDED flag is depracated. It used to be depracated
777 before first releasing SILC but came back. Now it is removed again
778 and should come back nomore. The FORWARDED flag was used only
779 by the JOINing procedure by forwarding the command packet to router.
780 Now, the JOINing procedure has been changed to more generic (due
781 to various router environment issues) and FORWARDED is not needed
782 anymore for anything. The protocol specification is yet to be
785 Now, removed silc_server_packet_forward from server and the flag
786 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
788 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
790 * Renamed NAMES command to USERS command. The NAMES was named that
791 due to historical reasons. Now it is renamed. Also, rewrote
792 parts of the USERS command. The nickname list is not sent anymore
793 by the server. Only Client ID and mode lists are sent in the USERS
794 command. Changed this also to the protocol specification.
796 The client now resolves the names and stuff after it receives
797 the USERS list from the server when joining to the channel.
799 * WHOIS and IDENTIFY commands has been changed to support multiple
800 Client ID's per command. One can now search for multiple users
801 in the network by sending only one WHOIS or IDENTIFY command.
802 Changed the code and the protocol specifications.
804 * Removed silc_server_command_identify_parse and changed that IDENTIFY
805 uses silc_server_command_whois_parse to parse the request. */
807 * If normal server, do not parse the WHOIS and IDENTIFY requests
808 before sending it to the router. Saves some time.
810 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Fixed JOIN command on client library. Wrong number of arguments
813 used to crash the client.
815 * Added silc_server_channel_has_global function to check whether
816 channel has global users or not.
818 * Added silc_server_channel_has_local function to check whether channel
819 has locally connected clients on the channel.
821 * The silc_server_remove_from_one_channel now checks whether the
822 channel has global users or not after given client was removed from
823 the channel. It also checks whether the channel has local clients
824 on the channel anymore. If it does not have then the channel entry
825 is removed as it is not needed anymore.
827 * The silc_server_notify now checks on JOIN notify whether the joining
828 client is one of locally connected or global. If it is global then
829 the channel has now global users on the channel and that is marked
830 to the channel entry. Also, it now saves the global client to
831 global list who is joining and JOINs it to the channel. This is
832 for normal server, that is.
834 Changed silc_server_send_notify_on_channel,
835 silc_server_packet_relay_to_channel and
836 silc_server_packet_send_to_channel check if we are normal server
837 and client has router set (ie. global client) do not send the
838 message to that client, as it is already routed to our router.
840 * Implemented LEAVE notify type handling in silc_server_notify
843 * Tested LEAVE command in router environment successfully. Tested
844 with two routers, two servers and two clients.
848 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
850 * Implemented SIGNOFF notify type handling in silc_server_notify
853 * silc_server_remove_id now removes the client entry from all channels
854 it has joined and thusly sends SIGNOFF notify type.
856 * Rewrote the NAMES list generation in server by removing two excess
857 loops. The lists are created now inside one loop.
859 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * silc_server_remove_channel_user checks now also global list
862 for channel and client.
864 * silc_server_new_channel_user checks now both local and global
865 list for channel and client. Fixed a bug in client id decoding.
866 Used to decode wrong buffer.
868 * silc_server_channel_message checks now both local and global
869 list for channel entry.
871 * Tested channel joining (hence JOIN) in router environment
872 successfully. Tested with two routers, two servers and two
875 * Tested channel message sending in router environment successfully.
877 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
879 * Added silc_server_save_channel_key into server.[ch] to save the
880 received channel key in Channel Key payload processing. It is
881 also used in JOIN command reply handling.
883 Equivalent function silc_client_save_channel_key added into
884 client.[ch] into client library.
886 * Changed JOIN command reply to send information whether the channel
887 was created or not (is existing already) and the channel key
888 payload. Changed protocol specs accordingly.
890 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
891 the request was sent by ID and not by nickname. Crashed on
894 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
897 now correctly save the received data.
899 * silc_server_free_sock_user_data now notifies routers in the
900 network about entities leaving the network.
902 At the same time implemented functions silc_server_remove_id
903 and silc_server_send_remove_id to receive and send REMOVE_ID
904 packets. The packet is used to notify routers in the network
905 about leaving entities. The ID removed will become invalid in
908 * Added function silc_idlist_del_server into server. Removes and
909 free's server entry from ID list.
911 * silc_server_private_message function now checks, if we are router,
912 that the destination ID really is valid ID, naturally.
914 * In router when NEW_ID packet is received (for new client) the
915 hash of the Client ID is saved in the ID Cache but the
916 client->nickname is set to NULL, instead of putting the hash
919 IDENTIFY command now also checks that client->nickname must be
920 valid. If it is not if will request the data from the server who
921 owns the client. Added new function
922 silc_server_command_identify_check.
924 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
925 to set the command to already allocated Command Payload.
927 * Tested private message sending in router environment with two
928 routers, two servers and two clients. Fixed minor bugs and now
931 * Fixed segfault from client's NAMES command. Used to crash if
934 * Forwarded packets must not be routed even if it is not destined
935 to the receiver. Changed server code comply with this.
937 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
939 * Added `require_reverse_mapping' boolean value to ServerParams
940 structure. If TRUE (not default) the server will require that
941 the connecting host has fully qualified domain name.
943 If the reverse mapping is not required and hostname could not be
944 found the IP address is used as hostname.
946 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Implemented version string checking to both client and server.
949 The check is incomplete currently due to the abnormal version
950 strings used in development version of SILC.
952 * Changed all command functions in server to use the new
955 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
957 * Changed char *data to unsigned char *data in ID Cache system to
958 support binary data as ID Cache data. Changed code to support
959 binary data in lib/silccore/idcache.c.
961 * Renamed silc_server_packet_relay_command_reply to
962 silc_server_command_reply as it is normal packet receiving
963 function. Rewrote the function to accept command replys for
964 servers and not only for clients.
966 * Mark remote router always as registered server if we are connecting
967 to it. Otherwise, commands sent by the router to us are ignored.
969 * All ID List find routines now returns the ID Cache Entry pointer
970 as well if requested.
972 * WHOIS command works now in router environment, tested with two
973 routers, two servers and two clients.
975 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
976 in router environment (as it is almost equivalent to WHOIS) but
977 hasn't been tested thoroughly. Added new functions:
979 silc_server_command_identify_parse
980 silc_server_command_identify_send_reply
981 silc_server_command_identify_from_client
982 silc_server_command_identify_from_server
984 * Disabled route cache adding because adding two different ID's with
985 same IP replaces the old cache entry thus giving wrong route.
986 The entry->router->connection is always the fastest route anyway
987 so route cache may not be needed. Of course, new routes maybe
988 established after receiving the ID when the entry->router->connection
989 might not be anymore the most optimal.
991 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Add route cache for received ID for fast routing.
995 * Added silc_server_packet_route to route received packet on router
996 that is not destined to us.
998 * Renamed silc_server_get_route to silc_server_route_get.
1000 * Added id_string and id_string_len fields into SilcServer to
1001 include encoded ServerID for fast comparing without excess
1002 encoding of the ID's.
1004 * Cleaned up WHOIS command on server side. Added following static
1007 silc_server_command_whois_parse
1008 silc_server_command_whois_check
1009 silc_server_command_whois_send_reply
1010 silc_server_command_whois_from_client
1011 silc_server_command_whois_from_server
1013 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1014 arguments in command replies. All command functions should be
1015 updated to use this macro.
1017 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Minor typo fixes on command reply handling on server.
1021 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Added silc_server_command_add_to_channel internal routine to add
1024 the client to the channel after router has created the channel and
1025 sent command reply to the server.
1027 * Added generic silc_server_send_command to send any command from
1030 * Use static buffer with ID rendering instead of duplicating data.
1032 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Fixed a channel user mode bug when joining to a channel server gave
1035 everybody channel founder rights, oops.
1037 * We mark ourselves as the router of the incoming server connection
1038 if we are router ourselves. This way we can check in some packet
1039 sending functions whether it is locally connected server. For
1040 incoming router connections we put NULL.
1042 * For router sending packets locally means now always sending the
1043 packet cell wide; to local clients and local servers. For normal
1044 server sending packet locally means sending it to only local
1047 * Fixed the JOIN command to really work in router environment. If the
1048 channel is created it is always created by the router. Router is
1049 also responsible of making the initial joining to the channel,
1050 sending JOIN notify to the sending server and distributing
1051 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1052 does not exist server doesn't do anything else but forward the
1053 command to the router which performs everything.
1055 * Added silc_server_send_channel_key function to send the Channel Key
1058 * Added silc_server_create_channel_key to create new channel key. The
1059 channel key is now re-generated everytime someone joins or leaves
1060 a channel, as protocol dictates. Note: channel->key_len is the
1063 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1065 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1066 packet_receive.[ch] to separate packet sending and receiving
1067 routines. The server.[ch] now includes everything else including
1068 actual packet processing (writing and reading data) and other
1071 Renamed silc_server_private_message_send_internal to
1072 silc_server_send_private_message. The routine is still though
1073 used only to relay private messages as server does not send
1074 private messages itself.
1076 Renamed silc_server_new_channel to silc_server_create_new_channel
1077 and added new function sicl_server_new_channel that handles the
1078 incoming New Channel packet. Added also new sending function
1079 silc_server_send_new_channel to send New Channel Payload.
1081 * Added new function silc_server_notify to process incoming notify
1082 packet to the server/router. Server may then relay the notify
1083 to clients if needed.
1085 * Added new function silc_server_new_channel_user to process incoming
1086 New Channel User packet. Router will redistribute the packet and
1087 send JOIN notify to its local clients and locally connected servers
1088 if needed. Normal server will send JOIN notify to its local client
1089 on same channel when received this packet. Added also corresponding
1090 sending function silc_server_send_new_channel_user to sent the
1093 * Added boolean route argument to send_notif_to_channel and
1094 packet_send_to_channel functions to attempt to route the packet
1095 if it is TRUE and send only locally if it is FALSE.
1097 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * silc_server_replace_id now broadcasts the received replace ID
1100 packet if it is not broadcast packet already. The router must
1101 broadcast to inform other routers about changed ID.
1103 * Added backpointer to server's router into SilcServer context in
1104 silcd/server_internal.h.
1106 * Fixed silc_server_packet_broadcast to send correct broadcast
1109 * The channel key is now distributed to the local client as soon
1110 as it is received from the router (in router environment) so that
1111 no other packet may be sent for the channel until client has
1114 * silc_server_remove_channel_user now broadcasts the received
1115 Remove Channel User packet if it is not broadcast packet already.
1116 The router must broadcast to inform other routers about removed
1119 * Added users field into SilcPacketContext that is a reference count
1120 of the context. One can increase the reference count by calling
1121 silc_packet_context_dup which is now changed to just increase the
1122 reference count instead of duplicating the data. The reference
1123 count is decresed by calling silc_packet_context_free that will
1124 free the data after the reference count hits zero.
1126 For now on the packet context and everything allocated into it
1127 (including the raw packet from network) must be freed by calling
1128 the new silc_packet_context_free function. Added also new function
1129 silc_packet_context_alloc that must be used now to allocate the
1130 context. This also means that if a routine is asynchronous from
1131 silc_[client/server]_packet_parse_type the packet context must
1132 be duplicated by calling silc_packet_context_dup. Otherwise it
1133 gets free'd after silc_[client/server]_packet_parse_type returns.
1134 Also, one must remember that if packet is duplicated then its
1135 reference count must be decresed by calling the free function as
1136 many times as it was duplicated.
1138 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1139 from both client and server.
1141 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Made joining to a channel working in router environment.
1145 * Cleaned up JOIN command on server side and create function
1146 silc_server_command_join_channel internal routine to make the
1149 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Changed silc_command_pending list to SilcDList. Also, added
1152 `ident' field to SilcServerCommandPending structure to identify
1153 the reply and to call correct callback.
1155 Added silc_server_command_pending_check function to replace the
1156 corresnponding macro. The silc_command_pending list is not
1159 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1160 to set identifier to previously allocated Command Payload. It
1161 is used to set identifier for command when resending Command
1164 * Added silc_command_payload_encode_payload to encode Command
1165 Payload buffer from SilcCommandPayload structure.
1167 * Added silc_argument_payload_encode_payload to encode Argument
1168 payload buffer from SilcArgumentPayload structure.
1170 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Changed WHOIS command to support router connection on server side.
1173 The whois request is always sent to router unless the server is
1174 standalone server. After server has received the reply from the
1175 router will it send the reply to the client.
1177 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1178 broadcast received broadcast packet. The function is used only
1179 by router. The broadcast packet is always sent to the router's
1182 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1183 render given ID to printable string, for log files for example.
1185 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Made basic router to router connections working. At least they
1188 can now connect to each other but nothing really works the way
1189 they are supposed - yet.
1191 * Added new initiator token to RouterConnection configuration
1192 file in silcd/serverconfig.[ch]. It is used to tell whether we
1193 are the initiator to the remote router or whether we'll expect
1194 the other end to connect.
1196 * Moved registering of listener task to silc_server_init, hence
1197 the server starts listenning as soon as it is run, even if it
1198 does not have connections to other routers. Let's see how well
1201 * Changed default connection retry timeouts for more suitable in
1204 * Removed cipher and such arguments from silc_idlist_add_client
1205 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1206 Added new function silc_idlist_add_data to add the keys and stuff
1209 * Added SilcIDListData structure and added it to SilcClientEntry
1210 and SilcServerEntry as their first field in the structure. This
1211 way we can explicitly cast the ID entries to the SilcIDListData
1212 structure and get common data for the entries. In past, we had
1213 to first check what type of connection it is and then cast it to
1214 correct ID entry type. Now, we can directly cast the opaque
1215 pointer to the SilcIDListData (no matter what ID entry it actually
1216 is) and get the data needed.
1218 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1221 in some circumstances even if threre were timeout tasks, though not
1222 IO tasks, but tasks anyway. Now fixed.
1224 * Defined SilcServerConnection structure to hold connection specific
1225 stuff about directly connected servers and routers. The definition
1226 is currently in silcd/server_internal.h. I thought about having
1227 a bit more important role fro this struct but for now it is used
1228 only when connecting to other server (or router actually).
1230 * Added connecting retry support in server when connecting to
1231 router(s). The retry feature implement exponential backoff
1232 algorithm. Also, added SilcServerParams structure to hold default
1233 parameters for server. For now, it include these retry settings
1234 and are hard coded. After server is moded to be as Silc Server
1235 Library this structure will be more important.
1237 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Changed client librarys channel->clients table to SilcList and
1240 changed code accordingly.
1242 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Changed client's channel table to SilcList and changed code
1245 accordingly. Also changed SilcChannelClientEntry to include back-
1246 pointer to the channel so that client entry can use that structure
1247 as list as well and we have fast cross-reference to the channel.
1248 This change dramatically decreased the complexity of channel
1249 handling with client entry and vice versa (removed one extra
1250 loop when searching for channel entry from many functions).
1252 * Changed server->sim from table to SilcDList and changed code
1255 * NAMES command can now be used from user interface. It will show
1256 the user list on the channel, neatly.
1258 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1259 Code now saves realname of the user if it becomes available.
1261 * Renamed configure.in to configure.in.pre and made ./prepare
1262 script to automatically add correct version string to
1263 configure.in which it creates from configure.in.pre.
1265 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * NAMES command reply now shows users mode with the nickname when
1270 * Moved silc_client_ch[u]mode[_char] functions from
1271 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1272 place sucks, they are utility functions and should be in some
1275 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1277 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1280 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Added TRQ (efficient deque and list library) into lib/trq. This is
1285 a very good list library that is currently used in the SILC. Defined
1286 SilcList API over the library because I didn't like the API very
1287 much. See lib/trq/silclist.h for the API and examples of how to
1288 use the API. Fixed various places in the code to use the new
1289 SilcList API. The SilcList is meant for lists that has a structure
1290 already defined as a list. It is not suitable to add just some
1291 context to the list (in TRQ, the context is the list actually).
1293 So, I defined SilcDList that can be used for the purpose where
1294 predefined list structure does not exit. This can be used as
1295 such list. Now some context just can be added to the SilcDList.
1296 Currently this list is not used in the SILC just yet, though there
1297 are a lot places where this can replace dynamically allocated
1298 tables and I will fix these places, later, to use SilcDList.
1299 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1300 and use TRQ internally).
1302 Also fixed some annoying warning messages that the original TRQ
1303 code generated. Also minor changes to TRQ's Makefile.in.
1305 * Added support for querying by Client ID to both WHOIS and
1306 IDENTIFY commands into server, as required by the protocol.
1308 * Removed method function pointers from SilcBuffer structure. They
1309 weren't used to anything and just increased the context size for
1310 no good reason. This change also made silc_buffer_alloc and
1311 silc_buffer_free functions inline functions.
1313 * Disabled command flooding detection support until it's fixed so
1314 that it accepts commands in but does not execute them more than once
1317 * Added silc_net_localhost(), to return local hostname, into
1318 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1319 that must be initialized before calling silc_client_init.
1321 * Added new function: silc_server_send_notify_on_channels to send
1322 notify messages to all channels client has joined. It is assured
1323 that the message is sent only once per client.
1325 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1326 lib/silcutil/silcutil.[ch] as silc_format function. The new
1327 function is generic and is used by server as well, not only by
1328 the logging routines.
1330 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1331 the provided version string was not acceptable. Added new function:
1332 silc_ske_check_version into lib/silcske/silcske.h. The function
1333 must be implemented by the application (client or server) and it
1334 does not reside in the SKE library. The function checks the version
1335 string remote end sent.
1337 * Added back pointers (to opaque context and to SilcSocketConnection)
1338 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1340 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1341 duplicate packet context structure.
1343 * Changed `notify' client operation to send same arguments as client
1344 receives from server except for ID's. ID's are mapped to correct
1345 ID entry and that is returned. Also, if channel entry is not sent
1346 by server but the notify is for channel the channel entry is sent
1347 to application (otherwise application doesn't know that it is for
1348 channel (library gets it from packet's Destination ID)).
1350 * Added silc_client_remove_from_channels into client library to
1351 remove a client from all channels it has joined to. Used when
1352 received SIGNOFF notify from server. Added also new function
1353 silc_client_replace_from_channels to replace old ID entry with
1354 new ID entry on all channels. Used when received NICK_CHANGE
1357 * Fixed ID Cache list handling in silc_idlist_get_client in
1358 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1359 to get (or query) client by ID.
1361 * Updated TODO list.
1363 * Added connection authentication status message defined by the
1364 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1365 support for these into the code in client and server side.
1367 * Added generic function silc_client_send_command to send any command
1368 with variable argument list. Application should use this function
1369 to send commands if the command functions provided by the library
1370 does not suite for the application's user interface needs.
1372 * Added new `failure' client operation. Application is notified about
1373 received failure packet if client is executing a protocol. In this
1374 case the protocol's execution has failed.
1376 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1377 is required by the protocol.
1379 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1380 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1383 * Added status flag to SilcSKE object to indicate realtime status
1384 of the SKE protocol.
1386 * Application receives now exactly same command reply arguments as
1387 the library receives from server. However, if ID is received the
1388 corresponding ID entry is returned to the application (eg. Client
1389 ID is mapped to correct SilcClientEntry entry and that is returned).
1390 Changed command_reply client operation due to this change.
1392 * Changed all ID's in commands and in command replys as ID Payloads.
1393 Change affected both client and server side codes.
1395 All ID's sent in SILC network (with execption of ID's in SILC
1396 Packet header) are sent in ID Payload to support variable length
1399 * Server now notifies nick changes and notifies all clients on
1400 the channels about the new nickname (about the new Client ID,
1403 * Implemented CMODE command to change channel modes. Supports all
1404 channel modes defined by the protocol specs except ban and invite
1405 lists. (Also, private channel key mode is supported but support for
1406 setting private channel key in client is missing, thus, this mode
1407 has no effect on client side (except that server requires that the
1408 client uses private channel key and normal channel traffic does not
1411 Also, invite mode works per se, but INVITE command does not work
1412 yet correctly, so you can set channel as invite only channel but
1413 inviting clients to the channel does not work (it is yet to be
1414 thought what's the best way to do it).
1416 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1417 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1418 Implemented CUMODE command to change user's mode on the channel.
1419 Supports all modes defined by the protocol specs.
1421 * Added NAMES command reply to return users modes on the channel.
1423 * Removed unnecessary and slow ciphers from lib/silccrypt.
1425 * Set SO_KEEPALIVE option to connection sockets by default.
1427 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1429 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1430 redefined the Notify Payload into protocol specs.
1432 * Added silc_id_payload_parse_id to get ID directly from raw
1435 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1438 accept searching by Client ID as well.
1440 * Added support for LEAVE and SIGNOFF notify types in client library.
1442 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1443 to parse ID Payload from raw data.
1445 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Added flags parameter into silc_ske_assemble_security_properties
1448 function in lib/silcske/silcske.[ch].
1450 * Changed notify client operation to fit better for notify messages
1451 sent by server. The notify payload received from server is now
1452 passed to the application (after parsing it to SilcNotifyPayload).
1453 It is application's responsibility to retrieve the arguments
1454 from the payload and show the message the way it wants. The message
1455 sent by server is implementation specific.
1457 * Changed public keys to comply with the protocol specification.
1458 Old public keys are not supported anymore and are not compatible.
1460 * Removed nickname from Channel Payload as the latest draft removed
1461 it. The client must resolve the nickname from the NAMES command
1462 reply received when it joined the channel.
1464 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1466 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Fixed some errors in protocol specification drafts.
1470 * Created lib/silccore/silcnotify.c to implement Notify Payload
1471 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1472 generic payloads described by protocol specifications. The file
1473 includes implementations for ID Payload and Argument Payload.
1475 * Changed Command Payload implementation to use the new Argument
1476 Payload. Changed command_xxxx_payload to command_payload_xxxx
1477 to comply with SILC coding conventions.
1479 * Added suppport for Argument Payload handling in Notify Payload
1480 implementation as protocol requires it. Added the new support
1481 into server and client lib as well.
1483 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1485 * Added support for multiple nicknames on same channel. [n] is
1486 added locally to the nickname if there are more than one same
1487 nicknames on the channel.
1489 * Server now sends all nicknames that matched WHOIS request.
1490 Client also shows the list received from server.
1492 * Added TOPIC command to client side. User can now set and show
1493 current topic on channel.
1495 * Added MOTD command to client and server. Also, server sends the
1496 motd when client connects to the server.
1498 * Changed version strings to comply ISO 8601.
1500 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Fixed protocol error handling in client library. It should now
1503 cope even if the SKE fails for some reason.
1505 * Made new protocol specification drafts for submitting to IETF.
1507 * Implemented TOPIC command to server in silcd/command.c.
1509 * Added two new notify types into lib/silccore/silcnotify.h:
1510 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1511 notify nickname change and topic setting/change on a channel.
1513 * API change of command_reply operation in client library. The
1514 application gets now the status type received from server as well.
1516 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1518 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1520 * Cras fixed and optimized the packet handling even further and
1521 it should work now. Minor change to the prototype of function
1522 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1524 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Added new function into lib/silcutil/silcschedule.[ch]:
1527 silc_schedule_with_fd to select() a specified fd. The function
1528 returns after timeout expires or data arrives or goes. The
1529 function is used by packet routines to wait that all data is
1530 received from network.
1532 * Fixed data reading from network in lib/silccore/silcpacket.c.
1533 The code now assures that all data is read from the fd and then
1534 continues packet processing. This was a bug fix since the code
1535 used to drop some data in some circumstances.
1537 * Added new function into lib/silcclient/client.[ch]:
1538 silc_client_start_key_exchange to start key exchange after
1539 connection has been established to server. The code internally
1540 now uses this funtion but its main purpose was to provide it
1541 for applications that perform their own connecting. After
1542 application has created a connection it merely calls this
1543 function to start the key exchange between client and server.
1544 The library takes care of everything else after that.
1546 Updated also lib/silcclient/README to explain the usage of
1549 * Do not send to application information that connection has
1550 been established. Application gets notified it by connect
1553 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Applied cras's patch to add silc_schedule_one function. The
1556 function runs scheduler once and returns.
1558 * Fixed the scheduler after cras messed it up. The timeout
1559 handling works now as it's supposed to work.
1561 * Added into lib/silccore/ silcnotify.h to include notify
1562 message types support. Changed silc_server_send_notify*
1563 functions, in server.[ch], to support those new notify types.
1564 Added the support for the notify types into client library,
1565 as well. Added new notify client operation into ops.h in
1568 * Changed silc_server_packet_send_to_channel to send normal
1569 packets instead of just channel message packets. The function
1570 is now used to send the notify packets to channels. It is not
1571 used to send channel message packets anymore, as server never
1574 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1575 va_arg()s as it seems to require it nowadays. I guess, if SILC
1576 is compiled with older va_arg() the new code should work anyway.
1578 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1580 * Splitted core library. Core library (lib/silccore) includes
1581 now only SILC protocol specific core (and common) components.
1582 Created new utility library (lib/silcutil) that includes more
1583 generic purpose stuff. The stuff for util library was taken
1584 from the old core library. This was minor and easy split.
1586 * Created SILC Client Library (lib/silcclient) that includes
1587 implementation of the SILC client without user interface. This
1588 was major move from silc/ directory. The code has been changed
1589 so that it is transparent towards the user interface. The
1590 silc/ directory includes now the same user interface as before
1591 and it uses the new client library. Read lib/silcclient/README.
1592 Basicly, the client library performs everything else related
1593 to SILC except user interface handling. Also, configuration
1594 files are considered to be part of user interface and library
1595 does not handle them.
1597 This change also changed a lot of structures, function naming etc.
1598 Most important change was that SilcClientWindow object was
1599 renamed to SilcClientConnection in the client library. Created
1600 also new file lib/silcclient/ops.h. Also added new files
1601 silc/local_command.[ch] and silc/client_ops.[ch].
1603 All these changes were made to make it easier for user interface
1604 designers to create what ever user interface for the SILC client
1607 It is also expected that the server will be moved to lib
1608 directory as well and SILC Server Library will be created;
1609 sometimes in the future.
1611 * Removed Local commands from lib/silccore/silccommand.h as
1612 they are application specific and new client library does not
1613 handle any of those anymore.
1615 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1616 old client implementation in silc/.
1618 * Added support for callback functions in SILC_LOG_* macros.
1619 Application can now set its own callbacks that will be called
1620 instead of using the default functions that will always print
1621 the debug messages to stderr (or stdout). Also, debugging can
1622 now be disabled by setting silc_debug to FALSE and re-enabled by
1623 setting it to TRUE. Note, that logging will still work even
1624 if debugging is disabled.
1626 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1627 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1628 silc_log_reset_debug_callbacks.
1630 * To enable debugging in silc client one must give now -d
1631 option on command line.
1633 * Changed silc_schedule_init to automatically allocate task queues
1634 if they are not allocated before calling it.
1636 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Added GMP 3.1 into math library.
1640 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1643 a channel in SILC network. The packet is used by servers and
1644 routers to notify other routers that user has left a channel.
1645 This little feature was missing until now. Added the feature
1646 to protocol specification as well.
1648 Added functions: silc_server_send_remove_channel_user and
1649 silc_server_remove_channel_user into server.[ch].
1651 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1652 lib/silccore/silcpacket.h. However, they are not implemented
1655 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Fixed joining to a channel and sending channel messages
1658 between server and router. The channel message sending should
1659 now work inside a cell.
1661 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Fixed the private message sending between server and router.
1664 The private message sending should now work inside a cell.
1666 * Added silc_server_replace_id into server.[ch] to replace
1667 existing ID in the SILC network.
1669 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1670 and silc_idlist_replace_server_id into idlist.[ch] in server.
1672 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Fixed the server to server connections. Server can again now
1675 connect to router. Router to router connections probably does
1678 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1680 * Added dynamic protocol registering support. Now protocols can
1681 registered and unregistered on the fly. Patch by cras.
1683 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1685 * Added lib/contrib directory to hold routines that some platforms
1686 don't have but are needed by SILC.
1688 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1689 into lin/contrib to provide getopt() and getopt_long() for
1690 those who don't have it.
1692 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Added AWAY command to client. When away message is set and
1695 client receives a private message packet the client automatically
1696 replies to the sender with the away message.
1698 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1699 bug seemed to be the cause of recent problems when compiling
1702 * Added version detection support to SKE protocol specification
1703 and added the new changes to the SKE implementation as well.
1704 There were other minor changes in the SKE protocol as well.
1706 Many changes in lib/silcske/silcske.[ch] and in
1707 lib/silcske/payload.[ch].
1709 * Added ^U functionality, clear input line. Patch from cras.
1711 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Mainly small bugfixes on core library. Fixed some debugging
1714 logging and buffer overflow in silclog.c.
1716 * Updated config.sub and config.guess on the distribution tree.
1718 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Added command lagging support in server. Client may execute
1721 commands now only once in two seconds.
1723 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1725 * Optimized packet reception. MAC computation and checking is now
1726 also more optimized. A lot previously duplicated code is now
1727 used as generic by both client and server.
1729 * Fixed key pair generation in clientutil.c
1731 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1733 * Added into lib/silccore/silcbufutil.[ch] new function;
1734 silc_buffer_realloc.
1736 * Moved generic packet sending/encryption functions to
1737 lib/silccore/silcpacket.[ch] from client and server. Some
1738 rewriting of the functions.
1740 * Moved all generic packet reception/decryption functions to
1741 lib/silccore/silcpacket.[ch] from client and server. The
1742 packet processing is now much cleaner in both client and server.
1743 These were major changes in both client and server.
1745 * Created many common functions in server to do packet sending.
1746 Previously code were duplicated a lot, this has been removed
1749 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Rewrote major parts of the ID cache system. Don't know
1752 whether it is better now or not but at least the API is more
1755 * Major rewrite on ID cache stuff on client because of the ID
1756 cache API changes. Added idlist.c to client.
1758 * Also major rewrite on ID cache stuff on server as well.
1759 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1760 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1761 in hand, instead they are all put into the ID cache system now.
1762 All server_idlist_* routines uses ID cache now instead of
1763 traversing its own lists (those lists does not exist anymore).
1764 SilcIDList though still exists. Also, SilcXXXEntry's are
1767 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1769 * Finally made the SKE implementation compliant to the protocol
1770 specification. All mp integers are now binary encoded as
1771 opposed being HEX encoded.
1773 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1776 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1777 functions: silc_[encode/decode]_pem. Also added function
1778 silc_encode_pem_file to PEM encode with newlines ('\n') for
1781 * SILC public keys are now encoded either PEM or binary. Same
1782 option is for private keys as well. By default private keys
1783 are binary encoded and public keys PEM encoded. Silly HEX
1784 encoding were removed.
1786 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1787 function to create fingerprints.
1789 * Fixed a bug in SHA1; does not change the original data anymore.
1791 * Partly implemented INFO command on client and server side.
1792 Fixed CLEAR command. Changes to SERVER command; show current
1793 server(s) when giving command without arguments. Added
1794 VERSION command to client.
1796 * Added check to server that unregistered connections cannot
1797 execute commands (unless it is specificly allowed).
1799 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * Fixed screen refresh.
1803 * Fixed channel joining bug from client. On some circumstances
1804 client tried to join to a channel it had already joined.
1806 * Added public key verification process into client's protocol.c.
1807 The client now verifies the public key from user and saves
1808 it into ~./silc/serverkeys/ directory.
1810 Added into: clientutil.[ch]: silc_client_verify_server_key.
1812 * Changed SKE protocol's silc_ske_initiator_finish function
1813 to accept callback function that verifies the received public
1814 key. Removed old silc_ske_verify_public_key function.
1816 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1819 silc_pkcs_private_key[_data]_set.
1821 * Made the password and public authentication more cleaner in
1822 server's protocol.c.
1824 * Removed historic and obsolete protocol `channel_auth' from
1825 both client and server.
1827 * Removed wrong way of sending command status messages from
1828 server to client in server's command.c. The old way violated
1829 protocol specification.
1831 Changes to silccore/silccommand.[ch]: removed
1832 silc_command_encode_status_payload -> not needed anymore,
1833 changed silc_command_encode_payload_va to accept extra
1834 argument on variable argument list. The argument type must
1835 now be provided to the function. Also, added new function:
1836 silc_command_encode_reply_payload_va which is same as
1837 normal command_encode_payload_va except command status type
1838 is provided as extra argument.
1840 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1842 * Added ~./silc directory handling. The directory includes the
1843 public and private keys for the client.
1845 Added silc_client_check_silc_dir, silc_client_create_identifier
1846 and silc_client_load_keys.
1848 * Implemented SILC protocol compliant public key. Added public
1849 and private key saving to and loading from files.
1851 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1852 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1853 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1854 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1855 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1857 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1858 silc_pkcs_load_[public/private]_key.
1860 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Added silc_server_get_route (route.[ch]) to get connection
1863 data for the fastest route for given ID.
1865 * Implemented INVITE command on client and server. The command
1866 were re-defined in the SILC Protocol Specification and the
1867 implementation now complies with the specification.
1869 * Implemented PING command on client and server.
1871 * Implemented NAMES command on client and server. The server side
1872 supports currently only normal server not router server yet.
1873 Some changes to NAMES definition in SILC protocol specification.
1875 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Implemented LEAVE command on client and server.
1879 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1880 again. This change was made to the protocol as well. Server
1881 should not violate the protocol specification anymore.
1883 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1886 was tested. SOCKS4 was not but should work anyway.
