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 * Added new key_agreement client callback and also defined the
15 Key Agreement library API for the application.
17 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
19 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
20 is used by clients to request key negotiation between another
21 client in the SILC network. If the negotiation is started it
22 is performed using the SKE protocol. The result of the
23 negotiation, the secret key material, can be used for example
24 as private message key.
26 Implemented the Key Agreement payload into the files
27 lib/silccore/silauth.[ch].
29 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
31 * Redefined ciphers for the SILC protocol. Added some new ciphers
32 and defined the key lengths for the algorithms. Changed the
33 code accordingly. The default key length is now 256 bits.
35 * Fixed SKE key distribution function silc_ske_process_key_material
36 when the key length is more than 128 bits. The default key
37 length in SILC is now 256 bits.
39 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
40 to indicate unsupported algorithm.
42 * Renamed rijndael.c to aes.c and all functions as well.
44 * Fixed a long standing channel key setting bug in client library.
45 Weird that it has never surfaced before.
47 * Fixed bug in channel deletion. If the entire channel is removed
48 then it must also delete the references of the channel entry
49 from the client's channel list as the client's channel entry and
50 the channel's client entry share same memory.
52 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
54 * Implemented CONNECT and SHUTDOWN commands in the client.
56 * Implemented CLOSE command to the client.
58 * Added the function silc_idlist_find_server_by_name into the
59 files silcd/idlist.[ch].
61 Added the function silc_idlist_find_server_by_conn into the
62 files silcd/idlist.[ch].
64 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
66 * DIE command was renamed to SHUTDOWN. Updated the both code
69 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
70 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
72 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
75 * Added function silc_server_create_connection function to create
76 connection to remote router. My server implementation actually
77 does not allow router to connect to normal server (it expects
78 that normal server always initiates the connection to the router)
79 so the CONNECT command is only good for connecting to another
82 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
84 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
85 or some other client was kicked from the channel.
87 Implemented the handling of the notify type to both client
90 Implemented silc_server_send_notify_kicked to send the KICKED
91 notify. It is used to send it to the server's primary router.
93 * Implemented the KICK command into server and client.
95 * Added `query' argument to the silc_idlist_get_client function
96 to indicate whether to query the client from server or not if
99 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
100 to indicate that the client is not channel founder.
104 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
106 * Removed the rng context from SilcPacketContext structure and
107 changed that the packet routine uses the Global RNG API.
109 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Added support for quit message that client can "leave" on the
112 channel when it quits the SILC. It is ditributed inside the
113 SILC_NOTIFY_TYPE_SIGNOFF notify type.
115 Added silc_server_free_client_data that will take the
116 signoff message as argument.
118 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
120 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
122 * Updated parts of the protocol specification to keep it up
125 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
127 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
128 payloads in one packet.
130 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
131 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
132 use now the new List flag.
134 * Also deprecated the following packet types: REPLACE_ID,
135 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
137 * Added list support for Notify packet in server.
139 * Added silc_server_send_notify_channel_change to send the
140 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
141 the silc_server_send_replace_id.
143 * Added silc_server_send_notify_nick_change to send the
144 NICK_CHANGE notify type. Deprecates the function
145 silc_server_send_replace_id.
147 * Added silc_server_send_notify_join to send the JOIN notify type.
148 Deprecates the function silc_server_send_new_channel_user.
150 * Added silc_server_send_notify_leave to send LEAVE notify type.
151 Deprecates the function silc_server_send_remove_channel_user.
153 * Added silc_server_send_notify_cmode and
154 silc_server_send_notify_cumode to send CMODE and CUMODE notify
155 types. Deprecates the silc_server_send_set_mode function.
157 * Added SERVER_SIGNOFF notify type to indicate that server has
158 quit. This means that all clients on the channel from that
159 server will drop. This can be also used when netsplit happens.
161 Deprecated REMOVE_ID packet type since it is not needed anymore
164 Added silc_server_send_notify_server_signoff to send the
165 SERVER_SIGNOFF notify type. Deprecates the function
166 silc_server_send_remove_id.
168 Added also silc_server_send_notify_signoff to send the
171 * Employed the PKCS #1. It is the mandatory way to do RSA in the
172 SILC protocol from this day on. Changed the protocol
173 specification as well.
175 * Added silc_server_send_notify_topic_set to send TOPIC_SET
176 notify type. It is used between routers to notify about
177 topic changes on a channel.
179 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
182 * Partly updated the protocol specification to comply with the
183 changes now made. It is still though a bit outdated.
185 * The JOIN notify type now takes one extra argument <Channel ID>.
186 The packet used to be destined to the channel but now the
187 JOIN type may be sent as list thus it is impossible to
188 destine it to any specific channel. By adding this argument
189 it is again possible.
191 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Added CREDITS file. The CHANGES and CREDITS file will appear
194 in the distribution as well.
196 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
198 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
199 types in the server's silcd/packet_receive.c.
201 * Implemented CMODE and CUMODE to work in router environment.
203 * Fixed minor encoding and decoding buglet from the
204 lib/silccore/silcmode.c.
206 * Fixed buffer overflow from lib/silcclient/command.c in USERS
209 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
211 * Changed all SilcConfigServer* and silc_config_server* to
212 SilcServerConfig* and silc_server_config*, respectively.
215 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
217 * Associated the ID (client or server ID) to the Authentication
218 Payload to avoid any possibility of forging. Updated the
219 protocol specification and the code accordingly.
221 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * The RSA key length is now save to the RsaKey context in the
224 key generation process in lib/silccrypt/rsa.c. The key length
225 is now used to figure out the maximum size of the block allowed
226 to be encrypted/signed.
228 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
229 is equivalent to the silc_mp_mp2bin but does not allocate any
232 * Changed silc_mp_mp2bin API to take length argument. If it is
233 non-zero then the buffer is allocated that large. If zero, then
234 the size is approximated using silc_mp_sizeinbase, which however
237 * Created Global RNG API which is global RNG that application can
238 initialize. After initializing, any routine anywhere in the
239 code (including library) can use RNG without allocating a new
240 RNG object. This was done to allow this sort of use of the
241 RNG in code that has no chance to allocate RNG object. All
242 applications currently allocate this and many routines in the
243 library use this. Affected file lib/silccrypt/silcrng.[ch].
245 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
246 it to use the Global RNG API.
248 * Defined Authentication Payload into protocol specification that
249 is used during SILC session to authenticate entities. It is
250 used for example by client to authenticate itself to the server
251 to obtain server operator privileges.
253 Implemented this payload into the lib/silccore/silcauth.[ch].
254 Implemented also routines for public key based authentication
255 as the new protocol specification dictates.
257 Moved definitions of different authentication methods from
258 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
260 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
261 silc_pkcs_verify and silc_pkcs_sign_with_hash and
262 silc_pkcs_verify_with_hash functions into the file
263 lib/silccrypt/silcpkcs.[ch].
265 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
267 * The client entry's userinfo pointer must be always valid.
268 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
269 will fail since it requires the userinfo. Now, the userinfo
270 is allocated as "" if actual userinfo does not exist. Actually,
271 it must exist and it is totally Ok to drop client connections
272 that does not announce the userinfo. However, we will make
273 this workaround for now.
275 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
276 to return the remote port by socket.
278 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
280 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
281 SILC_SERVER_PENDING_EXEC and added an new macro
282 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
283 data or when error occurs while processing the pending command.
285 Added new argument `destructor' into silc_server_command_pending
286 and to the SilcServerCommandPending object. This destructor is
287 now called after calling the pending callback or if error occurs
288 immediately. If error occurs the actual pending callback won't
289 be called at all - only the destructor. The destructor may be
290 NULL if destructor is not needed.
292 All this applies for client library code as well. Similar
293 changes were made there as well for the pending commands.
295 In the client, the application must now allocate the
296 SilcClientCommandContext with the silc_client_command_alloc
299 * Added reference counter to the SilcServerCommandContext. Added
300 function silc_server_command_alloc and silc_server_command_dup
303 Same type of functions added to the client library for the same
306 * Removed the cmd_ident from IDListData away since it is now
307 global for all connections. It is the command identifier used
308 in command sending and with pending commands. The affected file
311 * Added reference counter to the SilcSocketConnection objecet to
312 indicate the usage count of the object. The object won't be
313 freed untill the reference counter hits zero. Currently only
314 server uses this, and client ignores it. The client must be
315 set to use this too later. The affected files are
316 lib/silccore/silcsockconn.[ch]. Added also the function
317 silc_socket_dup to increase the reference counter.
319 This was mainly added because it is possible that the socket
320 is removed underneath of pending command or other async
321 operation. Now it won't be free'd and proper DISCONNECTING
322 flags, etc. can be set to avoid sending data to connection that
323 is not valid anymore.
325 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
326 the connection. After that it sets SILC_SET_DISCONNECTED.
327 It is, however, possible that the socket data is not still freed.
328 The silc_server_packet_process now checks that data is not
329 read or written to connection that is DISCONNECTED. The socket
330 get's freed when the reference counter hits zero.
332 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Changed the client operation API: channel_message operation's
335 `sender' is now the client entry of the sender, not the nickname
336 and the `channel' is the channel entry, not the channel name.
338 In the private_message operation the `sender' is now also the
339 client entry of the sender not the nickname.
341 Affected file is lib/silcclient/ops.h and all applications
342 using the client operations.
344 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Moved the calling of ops->connect() from connect_to_server_final
347 into receive_new_id functin since that is the point when the
348 client is actually allowed to send traffic to network. The
349 affected file is lib/silcclient/client.c.
351 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
354 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
355 (if needs broadcasting) instead of broadcasting the packets one
356 by one which would make a burst in the network traffic.
358 * Added `broadcast' argument to the functions in silcd/server.[ch]
359 silc_server_create_new_channel[_with_id] to indicate whether
360 to send New Channel packet to primary router.
362 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Added new function into the silcd/server.[ch] files:
365 silc_server_create_new_channel_with_id to create new channel with
366 already existing Channel ID.
368 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
369 lib/silccore/silcpacket.h. This packet is used t send list of
370 Set Mode payloads inside one packet. Server uses this to set
371 the modes for the channels and clients on those channels, that it
372 announced to the router when it connected to it. The protocol
373 specification has been updated accordingly.
375 * The silc_server_new_channel did not handle the packet coming
376 from normal server as it normally does not send that. However,
377 when it announces its channels it does send it. Implemented
378 the support for that.
380 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
381 into the file lib/silccore/id.h.
383 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Fixed memory leaks in the functions silc_idlist_del_client,
386 silc_idlist_del_channel and silc_idlist_del_server in the file
387 silcd/idlist.c. All of those leaked like a sieve.
389 * Fixed some small memory leaks in the client's function
390 silc_client_notify_by_server.
392 * Added functions into silcd/server.c: silc_server_announce_clients,
393 silc_server_announce_channels and silc_server_announce_server.
394 These functions are used by normal and router server to announce
395 to its primary router about clients, channels and servers (when
396 router) that we own. This is done after we've connected to the
399 These functions effectively implements the following packet types:
400 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
401 and SILC_PACKET_NEW_ID_LIST.
403 * Added new functions into the silcd/packet_receive.[ch]:
404 silc_server_new_id_list, silc_server_new_channel_list and
405 silc_server_new_channel_user_list to handle the incoming
406 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
408 * Added support of changing Channel ID in the function
409 silc_server_replace_id. If the server that announces a channel
410 to the router already exists in the router (with same name but
411 with different Channel ID), router is responsible to send
412 Replace ID packet to the server and force the server to change
413 the Channel ID to the one router has.
415 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
416 client that the Channel ID has been changed by the router. The
417 normal server sends this to the client. Client must start using
418 the new Channel ID as the channel's ID.
420 Implemented handling of this new type into lib/silcclient/client.c
421 into the function silc_client_notify_by_server.
423 * Added new function silc_idlist_replace_channel_id into the files
424 silcd/idlist.[ch] to replace the Channel ID.
426 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Call silc_server_command_identify_check always when processing
429 the IDENTIFY command in silcd/command.c
431 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
434 send keepalive packets. The packet can be sent by clients,
437 Added function silc_socket_set_heartbeat into the file
438 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
439 If not set, the heartbeat is not performed. The actual
440 heartbeat is implemented in the low level socket connection
441 library. However, application is responsible of actually
444 Added silc_server_send_heartbeat to send the actual heartbeat
445 packet into silcd/packet_send.[ch]. Server now performs
446 keepalive with all connections.
448 * Added silc_task_get_first function into lib/silcutil/silctask.c
449 to return the timeout task with shortest timeout. There was a bug
450 in task unregistration that caused problems. TODO has been
451 updated to include that task system must be rewritten.
453 * The client library will now resolve the client information when
454 receiving JOIN notify from server for client that we know but
455 have incomplete information.
457 * Rewrote parts of silc_server_remove_from_channels and
458 silc_server_remove_from_one_channel as they did not remove the
459 channel in some circumstances even though they should've.
461 * Encryption problem encountered in server:
463 The LEAVE command used to send the Channel Key packet to the
464 router immediately after generating it. However, the code
465 had earlier sent Remove Channel user packet but not immediately,
466 ie. it was put to queue. The order of packets in the router
467 was that Channel Key packet was first and Remove Channel User
468 packet was second, even though they were encrypted in the
469 reverse order. For this reason, MAC check failed. Now, this
470 is fixed by not sending the Channel Key packet immediately but
471 putting it to queue. However, this is more fundamental problem:
472 packets that are in queue should actually not be encrypted
473 because packets that are sent immediately gets encrypted
474 actually with wrong IV (and thus MAC check fails). So, packets
475 that are in queue should be encrypted when they are sent to
476 the wire and not when they put to the queue.
478 However, the problem is that the current system has not been
479 designed to work that way. Instead, the packet is encrypted
480 as soon as possible and left to the queue. The queue is then
481 just purged into wire. There won't be any fixes for this
482 any time soon. So, the current semantic for packet sending
485 o If you send packet to remote host and do not force the send
486 (the packet will be in queue) then all subsequent packets to the
487 same remote host must also be put to the queue. Only after the
488 queue has been purged is it safe again to force the packet
491 o If you send all packets immediately then it safe to send
492 any of subsequent packets through the queue, however, after
493 the first packet is put to queue then any subsequent packets
494 must also be put to the queue.
496 Follow these rules and everything works fine.
498 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
500 * Added new function silc_server_remove_clients_by_server to
501 remove all client entries from ID list when the server connection
502 is lost. In this case it is also important to invalidate all
503 client entires as they hold the invalid server entry. This
504 fixes fatal bug when server has lost connection and will reconnect
507 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
509 * Made some sanity checks to silc_server_daemonise like to check
510 whether the requested user and group actually exists.
512 * Added sanity check to SKE's silc_ske_responder_finish to check
513 that the public and private key actually is valid.
515 * Invalidate the client's nickname when receiving Replace ID
516 packet and the Client ID is being replaced. This means that the
517 server will query the nickname if someone needs it (client)
520 * Sort the ID Cache in client library when the ID Cache data
521 has changed (needs sorting).
523 * Do not allow for SILC client to create several connections to
524 several servers. The client does not support windows right now
525 and generating multiple connections causes weird behaviour.
527 Irssi-silc client does support windows and can handle several
528 connections without problems, see: www.irssi.org and SILC plugin.
530 * Fixed some places where client was added to the IDList. The
531 rule of thumb is following (in order to get everything right):
532 If the client is directly connected local client then the
533 `connection' argument must be set and `router' argument must be
534 NULL to silc_idlist_add_client function. If the client is not
535 directly connected client then the `router' argument must
536 bet set and the `connection' argument must be NULL to the
537 silc_idlist_add_client function.
539 * The funtion silc_server_packet_send_local_channel actually did
540 not check whether the client was locally connected or not. It
541 does that now. Fixed a bug related to LEAVE command.
543 * Fixed Remove Channel User payload parsing bug in server's
544 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
546 * The server's silc_server_save_channel_key now checks also the
547 global ID list for the channel as it might not be in the local
548 list. Fixed a bug related to LEAVE command.
550 * Is this the end of the [<unknown>] buglet that has been lurking
551 around for a long time? A little for loop fix in server's
552 silc_server_command_whois_parse that is used by both IDENTIFY
553 and WHOIS command. At least, this was a clear bug and a cause
554 of one type of [<unknown>] buglet.
556 * WHOIS and IDENTIFY commands call the function
557 silc_server_command_[whois/identify]_check function even if
558 we are not router server.
560 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Added --with-gmp configuration option. If set the GMP
563 is always compiled in the SILC source tree. If not set then
564 it is checked whether the system has the GMP3 installed. If
565 it has then the GMP won't be compiled (the system's headers
566 and library is used), if it doesn't have it then the GMP is
567 compiled in the SILC source tree.
569 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Changed RSA private exponent generation to what PKCS #1
572 suggests. We try to find the smallest possible d by doing
573 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
574 not security fix but optimization.
576 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
578 * Added new config entry [Identity] to fork the server and run
579 it as specific user and group. A patch from Bostik.
581 * Imported Dotconf configuration library into lib/dotconf.
582 This will be used to create the SILC configuration files later.
583 It will appear in the distsribution after this commit.
585 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
587 * A big code auditing weekend happening. Auditing code for
588 obvious mistakes, bugs and errors. Also, removing any code
591 Removed files for being obsolete:
593 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
594 inline in the file lib/silcutil/silcbuffer.h)
596 o lib/silcutil/silcbufutil.c (the header has inline versions)
598 Changed code to fix possible error conditions:
600 o The buffer formatting routines now check that the destination
601 buffer really has enough space to add the data. This applies for
602 both buffer formatting and unformatting
603 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
604 unformatting was changed to accomodate following rules:
605 XXX_*STRING_ALLOC will allocate space for the data into the pointer
606 sent to the function while XXX_*STRING will not allocate or copy
607 the data into the buffer. Instead it sets the pointer from the
608 buffer into the pointer sent as argument (XXX_*STRING used to
609 require that the pointer must be allocated already). This change
610 makes this whole thing a bit more consistent and more optimized
611 (note that the data returned in the unformatting with XXX_*STRING
612 must not be freed now). The routines return now -1 on error.
614 o Tried to find all code that use buffer_format and buffer_unformat
615 and added return value checking to prevent formatting and
616 especially unformatting errors and possible subsequent fatal
619 o Changed ske->x and ske->KEY to mallocated pointers in
620 lib/silcske/silcske.h. Fixed possible data and memory leak.
622 o Added return value checking to all *_parse* functions. Fixed
623 many memory leaks as well.
625 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
626 so that buffer overflows would not happen. All code now also
627 checks the return value as it can fail.
629 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Added reconnection support to server if the normal server looses
632 its connection to the router (for example if router is rebooted).
633 The server performs normal reconnection strategy implemented
634 to the server. Affected file silcd/server.c.
636 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Added new packet type SILC_PACKET_SET_MODE that is used to
639 distribute the information about changed modes (for clients,
640 channels and clients channel modes) to all routers in the
641 network. Updated the protocol specification accordingly.
643 Added functions into silcd/packet_send.c and
644 silcd/packet_receive.c: silc_server_send_set_mode,
645 silc_server_set_mode.
647 Added new files silcmode.[ch] into lib/silccore that implements
648 the encoding and decoding of Set Mode Payload. Added new type
649 SilcSetModePayload. Moved the definitions of different modes
650 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
652 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Oops, a little mistake in server's connection authentication
655 protocol. The protocol is not ended with FAILURE but with
656 SUCCESS if the authentication is Ok. :) Affected file is
659 * Implemented NICK_CHANGE notify handling in server in the file
660 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
661 the local clients on the channel. After the changing nickname
662 in router environment snhould work and the [<unknown>] nickname
663 should appear no more.
665 The silc_server_replace_id function that receives the Replace ID
666 payload now sends the NICK_CHANGE notify type also in the file
667 silcd/packet_receive.c
669 * Changed WHOIS and IDENTIFY command to support the maximum amount
670 of arguments defined in protocol specs (3328 arguments). This
671 fixed a bug that caused problems when there were more than three
674 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * Added extra parameter, command identifier, to the
677 silc_client_send_command so that explicit command identifier
680 Changed that ID list routines uses specific command identifier
681 when sending WHOIS/IDENTIFY requests to the server so that they
682 can be identified when the reply comes back.
684 Affected files lib/silcclient/command.[ch],
685 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
687 * Added `sender' argument to silc_server_packet_send_to_channel
688 to indicaet the sender who originally sent the packet to us
689 that we are now re-sending. Ignored if NULL. Affected file
690 silcd/packet_send.[ch].
692 * Added some server statistics support in silcd/server_internal.h
693 SilcServerStatistics structure and around the server code. Also
694 send some nice statistics information when client is connecting
697 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Fixed channel ID decoding in server's JOIN command reply in
700 silcd/command_reply.c
702 * Fixed braodcasting of replace ID payload to not to send it if
703 we are standalone server in silcd/packet_receive.c.
705 * Fixed all channel message sending routines to not to send
706 packets to clients that has router set, since they are routed
707 separately in the same function earlier. Affects file
708 silcd/packet_send.c and all channel packet sending functions.
710 * In USERS reply, res_argv[i] are not allocated, the table
711 is allocated. Thus changed that free the table, not its
714 * In server's whois_check and identify_check if the client is
715 locally connected do not send any WHOIS commands - they are not
718 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Fixed some minor bugs in client when sending WHOIS command. The
721 arguments was in wrong order.
723 * Removed statis function add_to_channel from server in
724 silcd/command.c that was previously used with the joining but
727 * Tested USERS command in router environment successfully with two
728 routers, two servers and two clients.
730 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
732 * Reorganized the USERS command and command reply in client library
733 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
734 When the command is given by user we register a pending command
735 callback that will reprocess the command after the reply has been
736 received from the server. When reprocessing the packet we then
737 display the information. Thus, the USERS information is displayed
738 now in the command callback instead of in the command reply
739 callback. The processing of the command is same as previously
740 when server has sent the command reply in the JOINing process.
742 * Added to USERS command in silcd/command_reply.c to join the client,
743 we didn't use to know about, to the channel after we've created
744 a client entry for it. Also, for clienet we did know already still
745 check whether it is on the channel or not and add it if not.
747 * Removed silc_server_command_join_notify as the function and its
750 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
752 * Changed the client's pending command handling to the same as the
753 server's pending command handling. It is also now possible to
754 execute command reply functions from other command reply
755 function as the function callbacks for commands and command
756 replies are one and same. The pending commands are not static
757 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
758 in client connection context. Thus, pending commands are server
759 connection specific as it is convenient.
761 Changed the function silc_client_command_pending and
762 silc_client_command_pending_del and added new function
763 silc_client_command_pending_check. Removed the
764 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
767 * Added cmd_ident, current command identifier, to the client
768 connection context in lib/silcclient/client.h to keep track on
769 command identifiers used in command sending. Client's command reply
770 function handling now supports the mandatory command identifiers.
772 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
773 funtions in client to fully support pending command callbacks.
775 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
776 as one of the arguments to the application in the command reply
779 * NOTE: The FORWARDED flag is depracated. It used to be depracated
780 before first releasing SILC but came back. Now it is removed again
781 and should come back nomore. The FORWARDED flag was used only
782 by the JOINing procedure by forwarding the command packet to router.
783 Now, the JOINing procedure has been changed to more generic (due
784 to various router environment issues) and FORWARDED is not needed
785 anymore for anything. The protocol specification is yet to be
788 Now, removed silc_server_packet_forward from server and the flag
789 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
791 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Renamed NAMES command to USERS command. The NAMES was named that
794 due to historical reasons. Now it is renamed. Also, rewrote
795 parts of the USERS command. The nickname list is not sent anymore
796 by the server. Only Client ID and mode lists are sent in the USERS
797 command. Changed this also to the protocol specification.
799 The client now resolves the names and stuff after it receives
800 the USERS list from the server when joining to the channel.
802 * WHOIS and IDENTIFY commands has been changed to support multiple
803 Client ID's per command. One can now search for multiple users
804 in the network by sending only one WHOIS or IDENTIFY command.
805 Changed the code and the protocol specifications.
807 * Removed silc_server_command_identify_parse and changed that IDENTIFY
808 uses silc_server_command_whois_parse to parse the request. */
810 * If normal server, do not parse the WHOIS and IDENTIFY requests
811 before sending it to the router. Saves some time.
813 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Fixed JOIN command on client library. Wrong number of arguments
816 used to crash the client.
818 * Added silc_server_channel_has_global function to check whether
819 channel has global users or not.
821 * Added silc_server_channel_has_local function to check whether channel
822 has locally connected clients on the channel.
824 * The silc_server_remove_from_one_channel now checks whether the
825 channel has global users or not after given client was removed from
826 the channel. It also checks whether the channel has local clients
827 on the channel anymore. If it does not have then the channel entry
828 is removed as it is not needed anymore.
830 * The silc_server_notify now checks on JOIN notify whether the joining
831 client is one of locally connected or global. If it is global then
832 the channel has now global users on the channel and that is marked
833 to the channel entry. Also, it now saves the global client to
834 global list who is joining and JOINs it to the channel. This is
835 for normal server, that is.
837 Changed silc_server_send_notify_on_channel,
838 silc_server_packet_relay_to_channel and
839 silc_server_packet_send_to_channel check if we are normal server
840 and client has router set (ie. global client) do not send the
841 message to that client, as it is already routed to our router.
843 * Implemented LEAVE notify type handling in silc_server_notify
846 * Tested LEAVE command in router environment successfully. Tested
847 with two routers, two servers and two clients.
851 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
853 * Implemented SIGNOFF notify type handling in silc_server_notify
856 * silc_server_remove_id now removes the client entry from all channels
857 it has joined and thusly sends SIGNOFF notify type.
859 * Rewrote the NAMES list generation in server by removing two excess
860 loops. The lists are created now inside one loop.
862 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * silc_server_remove_channel_user checks now also global list
865 for channel and client.
867 * silc_server_new_channel_user checks now both local and global
868 list for channel and client. Fixed a bug in client id decoding.
869 Used to decode wrong buffer.
871 * silc_server_channel_message checks now both local and global
872 list for channel entry.
874 * Tested channel joining (hence JOIN) in router environment
875 successfully. Tested with two routers, two servers and two
878 * Tested channel message sending in router environment successfully.
880 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Added silc_server_save_channel_key into server.[ch] to save the
883 received channel key in Channel Key payload processing. It is
884 also used in JOIN command reply handling.
886 Equivalent function silc_client_save_channel_key added into
887 client.[ch] into client library.
889 * Changed JOIN command reply to send information whether the channel
890 was created or not (is existing already) and the channel key
891 payload. Changed protocol specs accordingly.
893 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
894 the request was sent by ID and not by nickname. Crashed on
897 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
900 now correctly save the received data.
902 * silc_server_free_sock_user_data now notifies routers in the
903 network about entities leaving the network.
905 At the same time implemented functions silc_server_remove_id
906 and silc_server_send_remove_id to receive and send REMOVE_ID
907 packets. The packet is used to notify routers in the network
908 about leaving entities. The ID removed will become invalid in
911 * Added function silc_idlist_del_server into server. Removes and
912 free's server entry from ID list.
914 * silc_server_private_message function now checks, if we are router,
915 that the destination ID really is valid ID, naturally.
917 * In router when NEW_ID packet is received (for new client) the
918 hash of the Client ID is saved in the ID Cache but the
919 client->nickname is set to NULL, instead of putting the hash
922 IDENTIFY command now also checks that client->nickname must be
923 valid. If it is not if will request the data from the server who
924 owns the client. Added new function
925 silc_server_command_identify_check.
927 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
928 to set the command to already allocated Command Payload.
930 * Tested private message sending in router environment with two
931 routers, two servers and two clients. Fixed minor bugs and now
934 * Fixed segfault from client's NAMES command. Used to crash if
937 * Forwarded packets must not be routed even if it is not destined
938 to the receiver. Changed server code comply with this.
940 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Added `require_reverse_mapping' boolean value to ServerParams
943 structure. If TRUE (not default) the server will require that
944 the connecting host has fully qualified domain name.
946 If the reverse mapping is not required and hostname could not be
947 found the IP address is used as hostname.
949 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Implemented version string checking to both client and server.
952 The check is incomplete currently due to the abnormal version
953 strings used in development version of SILC.
955 * Changed all command functions in server to use the new
958 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Changed char *data to unsigned char *data in ID Cache system to
961 support binary data as ID Cache data. Changed code to support
962 binary data in lib/silccore/idcache.c.
964 * Renamed silc_server_packet_relay_command_reply to
965 silc_server_command_reply as it is normal packet receiving
966 function. Rewrote the function to accept command replys for
967 servers and not only for clients.
969 * Mark remote router always as registered server if we are connecting
970 to it. Otherwise, commands sent by the router to us are ignored.
972 * All ID List find routines now returns the ID Cache Entry pointer
973 as well if requested.
975 * WHOIS command works now in router environment, tested with two
976 routers, two servers and two clients.
978 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
979 in router environment (as it is almost equivalent to WHOIS) but
980 hasn't been tested thoroughly. Added new functions:
982 silc_server_command_identify_parse
983 silc_server_command_identify_send_reply
984 silc_server_command_identify_from_client
985 silc_server_command_identify_from_server
987 * Disabled route cache adding because adding two different ID's with
988 same IP replaces the old cache entry thus giving wrong route.
989 The entry->router->connection is always the fastest route anyway
990 so route cache may not be needed. Of course, new routes maybe
991 established after receiving the ID when the entry->router->connection
992 might not be anymore the most optimal.
994 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
996 * Add route cache for received ID for fast routing.
998 * Added silc_server_packet_route to route received packet on router
999 that is not destined to us.
1001 * Renamed silc_server_get_route to silc_server_route_get.
1003 * Added id_string and id_string_len fields into SilcServer to
1004 include encoded ServerID for fast comparing without excess
1005 encoding of the ID's.
1007 * Cleaned up WHOIS command on server side. Added following static
1010 silc_server_command_whois_parse
1011 silc_server_command_whois_check
1012 silc_server_command_whois_send_reply
1013 silc_server_command_whois_from_client
1014 silc_server_command_whois_from_server
1016 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1017 arguments in command replies. All command functions should be
1018 updated to use this macro.
1020 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Minor typo fixes on command reply handling on server.
1024 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Added silc_server_command_add_to_channel internal routine to add
1027 the client to the channel after router has created the channel and
1028 sent command reply to the server.
1030 * Added generic silc_server_send_command to send any command from
1033 * Use static buffer with ID rendering instead of duplicating data.
1035 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Fixed a channel user mode bug when joining to a channel server gave
1038 everybody channel founder rights, oops.
1040 * We mark ourselves as the router of the incoming server connection
1041 if we are router ourselves. This way we can check in some packet
1042 sending functions whether it is locally connected server. For
1043 incoming router connections we put NULL.
1045 * For router sending packets locally means now always sending the
1046 packet cell wide; to local clients and local servers. For normal
1047 server sending packet locally means sending it to only local
1050 * Fixed the JOIN command to really work in router environment. If the
1051 channel is created it is always created by the router. Router is
1052 also responsible of making the initial joining to the channel,
1053 sending JOIN notify to the sending server and distributing
1054 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1055 does not exist server doesn't do anything else but forward the
1056 command to the router which performs everything.
1058 * Added silc_server_send_channel_key function to send the Channel Key
1061 * Added silc_server_create_channel_key to create new channel key. The
1062 channel key is now re-generated everytime someone joins or leaves
1063 a channel, as protocol dictates. Note: channel->key_len is the
1066 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1069 packet_receive.[ch] to separate packet sending and receiving
1070 routines. The server.[ch] now includes everything else including
1071 actual packet processing (writing and reading data) and other
1074 Renamed silc_server_private_message_send_internal to
1075 silc_server_send_private_message. The routine is still though
1076 used only to relay private messages as server does not send
1077 private messages itself.
1079 Renamed silc_server_new_channel to silc_server_create_new_channel
1080 and added new function sicl_server_new_channel that handles the
1081 incoming New Channel packet. Added also new sending function
1082 silc_server_send_new_channel to send New Channel Payload.
1084 * Added new function silc_server_notify to process incoming notify
1085 packet to the server/router. Server may then relay the notify
1086 to clients if needed.
1088 * Added new function silc_server_new_channel_user to process incoming
1089 New Channel User packet. Router will redistribute the packet and
1090 send JOIN notify to its local clients and locally connected servers
1091 if needed. Normal server will send JOIN notify to its local client
1092 on same channel when received this packet. Added also corresponding
1093 sending function silc_server_send_new_channel_user to sent the
1096 * Added boolean route argument to send_notif_to_channel and
1097 packet_send_to_channel functions to attempt to route the packet
1098 if it is TRUE and send only locally if it is FALSE.
1100 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1102 * silc_server_replace_id now broadcasts the received replace ID
1103 packet if it is not broadcast packet already. The router must
1104 broadcast to inform other routers about changed ID.
1106 * Added backpointer to server's router into SilcServer context in
1107 silcd/server_internal.h.
1109 * Fixed silc_server_packet_broadcast to send correct broadcast
1112 * The channel key is now distributed to the local client as soon
1113 as it is received from the router (in router environment) so that
1114 no other packet may be sent for the channel until client has
1117 * silc_server_remove_channel_user now broadcasts the received
1118 Remove Channel User packet if it is not broadcast packet already.
1119 The router must broadcast to inform other routers about removed
1122 * Added users field into SilcPacketContext that is a reference count
1123 of the context. One can increase the reference count by calling
1124 silc_packet_context_dup which is now changed to just increase the
1125 reference count instead of duplicating the data. The reference
1126 count is decresed by calling silc_packet_context_free that will
1127 free the data after the reference count hits zero.
1129 For now on the packet context and everything allocated into it
1130 (including the raw packet from network) must be freed by calling
1131 the new silc_packet_context_free function. Added also new function
1132 silc_packet_context_alloc that must be used now to allocate the
1133 context. This also means that if a routine is asynchronous from
1134 silc_[client/server]_packet_parse_type the packet context must
1135 be duplicated by calling silc_packet_context_dup. Otherwise it
1136 gets free'd after silc_[client/server]_packet_parse_type returns.
1137 Also, one must remember that if packet is duplicated then its
1138 reference count must be decresed by calling the free function as
1139 many times as it was duplicated.
1141 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1142 from both client and server.
1144 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1146 * Made joining to a channel working in router environment.
1148 * Cleaned up JOIN command on server side and create function
1149 silc_server_command_join_channel internal routine to make the
1152 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Changed silc_command_pending list to SilcDList. Also, added
1155 `ident' field to SilcServerCommandPending structure to identify
1156 the reply and to call correct callback.
1158 Added silc_server_command_pending_check function to replace the
1159 corresnponding macro. The silc_command_pending list is not
1162 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1163 to set identifier to previously allocated Command Payload. It
1164 is used to set identifier for command when resending Command
1167 * Added silc_command_payload_encode_payload to encode Command
1168 Payload buffer from SilcCommandPayload structure.
1170 * Added silc_argument_payload_encode_payload to encode Argument
1171 payload buffer from SilcArgumentPayload structure.
1173 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Changed WHOIS command to support router connection on server side.
1176 The whois request is always sent to router unless the server is
1177 standalone server. After server has received the reply from the
1178 router will it send the reply to the client.
1180 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1181 broadcast received broadcast packet. The function is used only
1182 by router. The broadcast packet is always sent to the router's
1185 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1186 render given ID to printable string, for log files for example.
1188 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Made basic router to router connections working. At least they
1191 can now connect to each other but nothing really works the way
1192 they are supposed - yet.
1194 * Added new initiator token to RouterConnection configuration
1195 file in silcd/serverconfig.[ch]. It is used to tell whether we
1196 are the initiator to the remote router or whether we'll expect
1197 the other end to connect.
1199 * Moved registering of listener task to silc_server_init, hence
1200 the server starts listenning as soon as it is run, even if it
1201 does not have connections to other routers. Let's see how well
1204 * Changed default connection retry timeouts for more suitable in
1207 * Removed cipher and such arguments from silc_idlist_add_client
1208 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1209 Added new function silc_idlist_add_data to add the keys and stuff
1212 * Added SilcIDListData structure and added it to SilcClientEntry
1213 and SilcServerEntry as their first field in the structure. This
1214 way we can explicitly cast the ID entries to the SilcIDListData
1215 structure and get common data for the entries. In past, we had
1216 to first check what type of connection it is and then cast it to
1217 correct ID entry type. Now, we can directly cast the opaque
1218 pointer to the SilcIDListData (no matter what ID entry it actually
1219 is) and get the data needed.
1221 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1224 in some circumstances even if threre were timeout tasks, though not
1225 IO tasks, but tasks anyway. Now fixed.
1227 * Defined SilcServerConnection structure to hold connection specific
1228 stuff about directly connected servers and routers. The definition
1229 is currently in silcd/server_internal.h. I thought about having
1230 a bit more important role fro this struct but for now it is used
1231 only when connecting to other server (or router actually).
1233 * Added connecting retry support in server when connecting to
1234 router(s). The retry feature implement exponential backoff
1235 algorithm. Also, added SilcServerParams structure to hold default
1236 parameters for server. For now, it include these retry settings
1237 and are hard coded. After server is moded to be as Silc Server
1238 Library this structure will be more important.
1240 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Changed client librarys channel->clients table to SilcList and
1243 changed code accordingly.
1245 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Changed client's channel table to SilcList and changed code
1248 accordingly. Also changed SilcChannelClientEntry to include back-
1249 pointer to the channel so that client entry can use that structure
1250 as list as well and we have fast cross-reference to the channel.
1251 This change dramatically decreased the complexity of channel
1252 handling with client entry and vice versa (removed one extra
1253 loop when searching for channel entry from many functions).
1255 * Changed server->sim from table to SilcDList and changed code
1258 * NAMES command can now be used from user interface. It will show
1259 the user list on the channel, neatly.
1261 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1262 Code now saves realname of the user if it becomes available.
1264 * Renamed configure.in to configure.in.pre and made ./prepare
1265 script to automatically add correct version string to
1266 configure.in which it creates from configure.in.pre.
1268 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1270 * NAMES command reply now shows users mode with the nickname when
1273 * Moved silc_client_ch[u]mode[_char] functions from
1274 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1275 place sucks, they are utility functions and should be in some
1278 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1280 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1283 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1287 * Added TRQ (efficient deque and list library) into lib/trq. This is
1288 a very good list library that is currently used in the SILC. Defined
1289 SilcList API over the library because I didn't like the API very
1290 much. See lib/trq/silclist.h for the API and examples of how to
1291 use the API. Fixed various places in the code to use the new
1292 SilcList API. The SilcList is meant for lists that has a structure
1293 already defined as a list. It is not suitable to add just some
1294 context to the list (in TRQ, the context is the list actually).
1296 So, I defined SilcDList that can be used for the purpose where
1297 predefined list structure does not exit. This can be used as
1298 such list. Now some context just can be added to the SilcDList.
1299 Currently this list is not used in the SILC just yet, though there
1300 are a lot places where this can replace dynamically allocated
1301 tables and I will fix these places, later, to use SilcDList.
1302 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1303 and use TRQ internally).
1305 Also fixed some annoying warning messages that the original TRQ
1306 code generated. Also minor changes to TRQ's Makefile.in.
1308 * Added support for querying by Client ID to both WHOIS and
1309 IDENTIFY commands into server, as required by the protocol.
1311 * Removed method function pointers from SilcBuffer structure. They
1312 weren't used to anything and just increased the context size for
1313 no good reason. This change also made silc_buffer_alloc and
1314 silc_buffer_free functions inline functions.
1316 * Disabled command flooding detection support until it's fixed so
1317 that it accepts commands in but does not execute them more than once
1320 * Added silc_net_localhost(), to return local hostname, into
1321 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1322 that must be initialized before calling silc_client_init.
1324 * Added new function: silc_server_send_notify_on_channels to send
1325 notify messages to all channels client has joined. It is assured
1326 that the message is sent only once per client.
1328 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1329 lib/silcutil/silcutil.[ch] as silc_format function. The new
1330 function is generic and is used by server as well, not only by
1331 the logging routines.
1333 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1334 the provided version string was not acceptable. Added new function:
1335 silc_ske_check_version into lib/silcske/silcske.h. The function
1336 must be implemented by the application (client or server) and it
1337 does not reside in the SKE library. The function checks the version
1338 string remote end sent.
1340 * Added back pointers (to opaque context and to SilcSocketConnection)
1341 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1343 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1344 duplicate packet context structure.
1346 * Changed `notify' client operation to send same arguments as client
1347 receives from server except for ID's. ID's are mapped to correct
1348 ID entry and that is returned. Also, if channel entry is not sent
1349 by server but the notify is for channel the channel entry is sent
1350 to application (otherwise application doesn't know that it is for
1351 channel (library gets it from packet's Destination ID)).
1353 * Added silc_client_remove_from_channels into client library to
1354 remove a client from all channels it has joined to. Used when
1355 received SIGNOFF notify from server. Added also new function
1356 silc_client_replace_from_channels to replace old ID entry with
1357 new ID entry on all channels. Used when received NICK_CHANGE
1360 * Fixed ID Cache list handling in silc_idlist_get_client in
1361 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1362 to get (or query) client by ID.
1364 * Updated TODO list.
1366 * Added connection authentication status message defined by the
1367 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1368 support for these into the code in client and server side.
1370 * Added generic function silc_client_send_command to send any command
1371 with variable argument list. Application should use this function
1372 to send commands if the command functions provided by the library
1373 does not suite for the application's user interface needs.
1375 * Added new `failure' client operation. Application is notified about
1376 received failure packet if client is executing a protocol. In this
1377 case the protocol's execution has failed.
1379 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1380 is required by the protocol.
1382 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1383 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1386 * Added status flag to SilcSKE object to indicate realtime status
1387 of the SKE protocol.
1389 * Application receives now exactly same command reply arguments as
1390 the library receives from server. However, if ID is received the
1391 corresponding ID entry is returned to the application (eg. Client
1392 ID is mapped to correct SilcClientEntry entry and that is returned).
1393 Changed command_reply client operation due to this change.
1395 * Changed all ID's in commands and in command replys as ID Payloads.
1396 Change affected both client and server side codes.
1398 All ID's sent in SILC network (with execption of ID's in SILC
1399 Packet header) are sent in ID Payload to support variable length
1402 * Server now notifies nick changes and notifies all clients on
1403 the channels about the new nickname (about the new Client ID,
1406 * Implemented CMODE command to change channel modes. Supports all
1407 channel modes defined by the protocol specs except ban and invite
1408 lists. (Also, private channel key mode is supported but support for
1409 setting private channel key in client is missing, thus, this mode
1410 has no effect on client side (except that server requires that the
1411 client uses private channel key and normal channel traffic does not
1414 Also, invite mode works per se, but INVITE command does not work
1415 yet correctly, so you can set channel as invite only channel but
1416 inviting clients to the channel does not work (it is yet to be
1417 thought what's the best way to do it).
1419 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1420 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1421 Implemented CUMODE command to change user's mode on the channel.
1422 Supports all modes defined by the protocol specs.
1424 * Added NAMES command reply to return users modes on the channel.
1426 * Removed unnecessary and slow ciphers from lib/silccrypt.
1428 * Set SO_KEEPALIVE option to connection sockets by default.
1430 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1432 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1433 redefined the Notify Payload into protocol specs.
1435 * Added silc_id_payload_parse_id to get ID directly from raw
1438 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1441 accept searching by Client ID as well.
1443 * Added support for LEAVE and SIGNOFF notify types in client library.
1445 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1446 to parse ID Payload from raw data.
1448 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Added flags parameter into silc_ske_assemble_security_properties
1451 function in lib/silcske/silcske.[ch].
1453 * Changed notify client operation to fit better for notify messages
1454 sent by server. The notify payload received from server is now
1455 passed to the application (after parsing it to SilcNotifyPayload).
1456 It is application's responsibility to retrieve the arguments
1457 from the payload and show the message the way it wants. The message
1458 sent by server is implementation specific.
1460 * Changed public keys to comply with the protocol specification.
1461 Old public keys are not supported anymore and are not compatible.
1463 * Removed nickname from Channel Payload as the latest draft removed
1464 it. The client must resolve the nickname from the NAMES command
1465 reply received when it joined the channel.
1467 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1469 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Fixed some errors in protocol specification drafts.
1473 * Created lib/silccore/silcnotify.c to implement Notify Payload
1474 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1475 generic payloads described by protocol specifications. The file
1476 includes implementations for ID Payload and Argument Payload.
1478 * Changed Command Payload implementation to use the new Argument
1479 Payload. Changed command_xxxx_payload to command_payload_xxxx
1480 to comply with SILC coding conventions.
1482 * Added suppport for Argument Payload handling in Notify Payload
1483 implementation as protocol requires it. Added the new support
1484 into server and client lib as well.
1486 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Added support for multiple nicknames on same channel. [n] is
1489 added locally to the nickname if there are more than one same
1490 nicknames on the channel.
1492 * Server now sends all nicknames that matched WHOIS request.
1493 Client also shows the list received from server.
1495 * Added TOPIC command to client side. User can now set and show
1496 current topic on channel.
1498 * Added MOTD command to client and server. Also, server sends the
1499 motd when client connects to the server.
1501 * Changed version strings to comply ISO 8601.
1503 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1505 * Fixed protocol error handling in client library. It should now
1506 cope even if the SKE fails for some reason.
1508 * Made new protocol specification drafts for submitting to IETF.
1510 * Implemented TOPIC command to server in silcd/command.c.
1512 * Added two new notify types into lib/silccore/silcnotify.h:
1513 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1514 notify nickname change and topic setting/change on a channel.
1516 * API change of command_reply operation in client library. The
1517 application gets now the status type received from server as well.
1519 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1523 * Cras fixed and optimized the packet handling even further and
1524 it should work now. Minor change to the prototype of function
1525 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1527 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1529 * Added new function into lib/silcutil/silcschedule.[ch]:
1530 silc_schedule_with_fd to select() a specified fd. The function
1531 returns after timeout expires or data arrives or goes. The
1532 function is used by packet routines to wait that all data is
1533 received from network.
1535 * Fixed data reading from network in lib/silccore/silcpacket.c.
1536 The code now assures that all data is read from the fd and then
1537 continues packet processing. This was a bug fix since the code
1538 used to drop some data in some circumstances.
1540 * Added new function into lib/silcclient/client.[ch]:
1541 silc_client_start_key_exchange to start key exchange after
1542 connection has been established to server. The code internally
1543 now uses this funtion but its main purpose was to provide it
1544 for applications that perform their own connecting. After
1545 application has created a connection it merely calls this
1546 function to start the key exchange between client and server.
1547 The library takes care of everything else after that.
1549 Updated also lib/silcclient/README to explain the usage of
1552 * Do not send to application information that connection has
1553 been established. Application gets notified it by connect
1556 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Applied cras's patch to add silc_schedule_one function. The
1559 function runs scheduler once and returns.
1561 * Fixed the scheduler after cras messed it up. The timeout
1562 handling works now as it's supposed to work.
1564 * Added into lib/silccore/ silcnotify.h to include notify
1565 message types support. Changed silc_server_send_notify*
1566 functions, in server.[ch], to support those new notify types.
1567 Added the support for the notify types into client library,
1568 as well. Added new notify client operation into ops.h in
1571 * Changed silc_server_packet_send_to_channel to send normal
1572 packets instead of just channel message packets. The function
1573 is now used to send the notify packets to channels. It is not
1574 used to send channel message packets anymore, as server never
1577 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1578 va_arg()s as it seems to require it nowadays. I guess, if SILC
1579 is compiled with older va_arg() the new code should work anyway.
1581 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1583 * Splitted core library. Core library (lib/silccore) includes
1584 now only SILC protocol specific core (and common) components.
1585 Created new utility library (lib/silcutil) that includes more
1586 generic purpose stuff. The stuff for util library was taken
1587 from the old core library. This was minor and easy split.
1589 * Created SILC Client Library (lib/silcclient) that includes
1590 implementation of the SILC client without user interface. This
1591 was major move from silc/ directory. The code has been changed
1592 so that it is transparent towards the user interface. The
1593 silc/ directory includes now the same user interface as before
1594 and it uses the new client library. Read lib/silcclient/README.
1595 Basicly, the client library performs everything else related
1596 to SILC except user interface handling. Also, configuration
1597 files are considered to be part of user interface and library
1598 does not handle them.
1600 This change also changed a lot of structures, function naming etc.
1601 Most important change was that SilcClientWindow object was
1602 renamed to SilcClientConnection in the client library. Created
1603 also new file lib/silcclient/ops.h. Also added new files
1604 silc/local_command.[ch] and silc/client_ops.[ch].
1606 All these changes were made to make it easier for user interface
1607 designers to create what ever user interface for the SILC client
1610 It is also expected that the server will be moved to lib
1611 directory as well and SILC Server Library will be created;
1612 sometimes in the future.
1614 * Removed Local commands from lib/silccore/silccommand.h as
1615 they are application specific and new client library does not
1616 handle any of those anymore.
1618 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1619 old client implementation in silc/.
1621 * Added support for callback functions in SILC_LOG_* macros.
1622 Application can now set its own callbacks that will be called
1623 instead of using the default functions that will always print
1624 the debug messages to stderr (or stdout). Also, debugging can
1625 now be disabled by setting silc_debug to FALSE and re-enabled by
1626 setting it to TRUE. Note, that logging will still work even
1627 if debugging is disabled.
1629 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1630 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1631 silc_log_reset_debug_callbacks.
1633 * To enable debugging in silc client one must give now -d
1634 option on command line.
1636 * Changed silc_schedule_init to automatically allocate task queues
1637 if they are not allocated before calling it.
1639 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1641 * Added GMP 3.1 into math library.
1643 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1646 a channel in SILC network. The packet is used by servers and
1647 routers to notify other routers that user has left a channel.
1648 This little feature was missing until now. Added the feature
1649 to protocol specification as well.
1651 Added functions: silc_server_send_remove_channel_user and
1652 silc_server_remove_channel_user into server.[ch].
1654 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1655 lib/silccore/silcpacket.h. However, they are not implemented
1658 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * Fixed joining to a channel and sending channel messages
1661 between server and router. The channel message sending should
1662 now work inside a cell.
1664 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1666 * Fixed the private message sending between server and router.
1667 The private message sending should now work inside a cell.
1669 * Added silc_server_replace_id into server.[ch] to replace
1670 existing ID in the SILC network.
1672 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1673 and silc_idlist_replace_server_id into idlist.[ch] in server.
1675 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Fixed the server to server connections. Server can again now
1678 connect to router. Router to router connections probably does
1681 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Added dynamic protocol registering support. Now protocols can
1684 registered and unregistered on the fly. Patch by cras.
1686 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1688 * Added lib/contrib directory to hold routines that some platforms
1689 don't have but are needed by SILC.
1691 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1692 into lin/contrib to provide getopt() and getopt_long() for
1693 those who don't have it.
1695 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Added AWAY command to client. When away message is set and
1698 client receives a private message packet the client automatically
1699 replies to the sender with the away message.
1701 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1702 bug seemed to be the cause of recent problems when compiling
1705 * Added version detection support to SKE protocol specification
1706 and added the new changes to the SKE implementation as well.
1707 There were other minor changes in the SKE protocol as well.
1709 Many changes in lib/silcske/silcske.[ch] and in
1710 lib/silcske/payload.[ch].
1712 * Added ^U functionality, clear input line. Patch from cras.
1714 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Mainly small bugfixes on core library. Fixed some debugging
1717 logging and buffer overflow in silclog.c.
1719 * Updated config.sub and config.guess on the distribution tree.
1721 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1723 * Added command lagging support in server. Client may execute
1724 commands now only once in two seconds.
1726 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * Optimized packet reception. MAC computation and checking is now
1729 also more optimized. A lot previously duplicated code is now
1730 used as generic by both client and server.
1732 * Fixed key pair generation in clientutil.c
1734 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Added into lib/silccore/silcbufutil.[ch] new function;
1737 silc_buffer_realloc.
1739 * Moved generic packet sending/encryption functions to
1740 lib/silccore/silcpacket.[ch] from client and server. Some
1741 rewriting of the functions.
1743 * Moved all generic packet reception/decryption functions to
1744 lib/silccore/silcpacket.[ch] from client and server. The
1745 packet processing is now much cleaner in both client and server.
1746 These were major changes in both client and server.
1748 * Created many common functions in server to do packet sending.
1749 Previously code were duplicated a lot, this has been removed
1752 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Rewrote major parts of the ID cache system. Don't know
1755 whether it is better now or not but at least the API is more
1758 * Major rewrite on ID cache stuff on client because of the ID
1759 cache API changes. Added idlist.c to client.
1761 * Also major rewrite on ID cache stuff on server as well.
1762 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1763 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1764 in hand, instead they are all put into the ID cache system now.
1765 All server_idlist_* routines uses ID cache now instead of
1766 traversing its own lists (those lists does not exist anymore).
1767 SilcIDList though still exists. Also, SilcXXXEntry's are
1770 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Finally made the SKE implementation compliant to the protocol
1773 specification. All mp integers are now binary encoded as
1774 opposed being HEX encoded.
1776 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1779 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1780 functions: silc_[encode/decode]_pem. Also added function
1781 silc_encode_pem_file to PEM encode with newlines ('\n') for
1784 * SILC public keys are now encoded either PEM or binary. Same
1785 option is for private keys as well. By default private keys
1786 are binary encoded and public keys PEM encoded. Silly HEX
1787 encoding were removed.
1789 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1790 function to create fingerprints.
1792 * Fixed a bug in SHA1; does not change the original data anymore.
1794 * Partly implemented INFO command on client and server side.
1795 Fixed CLEAR command. Changes to SERVER command; show current
1796 server(s) when giving command without arguments. Added
1797 VERSION command to client.
1799 * Added check to server that unregistered connections cannot
1800 execute commands (unless it is specificly allowed).
1802 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1804 * Fixed screen refresh.
1806 * Fixed channel joining bug from client. On some circumstances
1807 client tried to join to a channel it had already joined.
1809 * Added public key verification process into client's protocol.c.
1810 The client now verifies the public key from user and saves
1811 it into ~./silc/serverkeys/ directory.
1813 Added into: clientutil.[ch]: silc_client_verify_server_key.
1815 * Changed SKE protocol's silc_ske_initiator_finish function
1816 to accept callback function that verifies the received public
1817 key. Removed old silc_ske_verify_public_key function.
1819 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1822 silc_pkcs_private_key[_data]_set.
1824 * Made the password and public authentication more cleaner in
1825 server's protocol.c.
1827 * Removed historic and obsolete protocol `channel_auth' from
1828 both client and server.
1830 * Removed wrong way of sending command status messages from
1831 server to client in server's command.c. The old way violated
1832 protocol specification.
1834 Changes to silccore/silccommand.[ch]: removed
1835 silc_command_encode_status_payload -> not needed anymore,
1836 changed silc_command_encode_payload_va to accept extra
1837 argument on variable argument list. The argument type must
1838 now be provided to the function. Also, added new function:
1839 silc_command_encode_reply_payload_va which is same as
1840 normal command_encode_payload_va except command status type
1841 is provided as extra argument.
1843 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1845 * Added ~./silc directory handling. The directory includes the
1846 public and private keys for the client.
1848 Added silc_client_check_silc_dir, silc_client_create_identifier
1849 and silc_client_load_keys.
1851 * Implemented SILC protocol compliant public key. Added public
1852 and private key saving to and loading from files.
1854 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1855 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1856 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1857 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1858 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1860 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1861 silc_pkcs_load_[public/private]_key.
1863 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1865 * Added silc_server_get_route (route.[ch]) to get connection
1866 data for the fastest route for given ID.
1868 * Implemented INVITE command on client and server. The command
1869 were re-defined in the SILC Protocol Specification and the
1870 implementation now complies with the specification.
1872 * Implemented PING command on client and server.
1874 * Implemented NAMES command on client and server. The server side
1875 supports currently only normal server not router server yet.
1876 Some changes to NAMES definition in SILC protocol specification.
1878 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Implemented LEAVE command on client and server.
1882 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1883 again. This change was made to the protocol as well. Server
1884 should not violate the protocol specification anymore.
1886 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1889 was tested. SOCKS4 was not but should work anyway.
