1 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4 is used by clients to request key negotiation between another
5 client in the SILC network. If the negotiation is started it
6 is performed using the SKE protocol. The result of the
7 negotiation, the secret key material, can be used for example
8 as private message key.
10 Implemented the Key Agreement payload into the files
11 lib/silccore/silauth.[ch].
13 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Redefined ciphers for the SILC protocol. Added some new ciphers
16 and defined the key lengths for the algorithms. Changed the
17 code accordingly. The default key length is now 256 bits.
19 * Fixed SKE key distribution function silc_ske_process_key_material
20 when the key length is more than 128 bits. The default key
21 length in SILC is now 256 bits.
23 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
24 to indicate unsupported algorithm.
26 * Renamed rijndael.c to aes.c and all functions as well.
28 * Fixed a long standing channel key setting bug in client library.
29 Weird that it has never surfaced before.
31 * Fixed bug in channel deletion. If the entire channel is removed
32 then it must also delete the references of the channel entry
33 from the client's channel list as the client's channel entry and
34 the channel's client entry share same memory.
36 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
38 * Implemented CONNECT and SHUTDOWN commands in the client.
40 * Implemented CLOSE command to the client.
42 * Added the function silc_idlist_find_server_by_name into the
43 files silcd/idlist.[ch].
45 Added the function silc_idlist_find_server_by_conn into the
46 files silcd/idlist.[ch].
48 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
50 * DIE command was renamed to SHUTDOWN. Updated the both code
53 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
54 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
56 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
59 * Added function silc_server_create_connection function to create
60 connection to remote router. My server implementation actually
61 does not allow router to connect to normal server (it expects
62 that normal server always initiates the connection to the router)
63 so the CONNECT command is only good for connecting to another
66 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
69 or some other client was kicked from the channel.
71 Implemented the handling of the notify type to both client
74 Implemented silc_server_send_notify_kicked to send the KICKED
75 notify. It is used to send it to the server's primary router.
77 * Implemented the KICK command into server and client.
79 * Added `query' argument to the silc_idlist_get_client function
80 to indicate whether to query the client from server or not if
83 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
84 to indicate that the client is not channel founder.
88 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Removed the rng context from SilcPacketContext structure and
91 changed that the packet routine uses the Global RNG API.
93 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
95 * Added support for quit message that client can "leave" on the
96 channel when it quits the SILC. It is ditributed inside the
97 SILC_NOTIFY_TYPE_SIGNOFF notify type.
99 Added silc_server_free_client_data that will take the
100 signoff message as argument.
102 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
104 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
106 * Updated parts of the protocol specification to keep it up
109 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
112 payloads in one packet.
114 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
115 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
116 use now the new List flag.
118 * Also deprecated the following packet types: REPLACE_ID,
119 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
121 * Added list support for Notify packet in server.
123 * Added silc_server_send_notify_channel_change to send the
124 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
125 the silc_server_send_replace_id.
127 * Added silc_server_send_notify_nick_change to send the
128 NICK_CHANGE notify type. Deprecates the function
129 silc_server_send_replace_id.
131 * Added silc_server_send_notify_join to send the JOIN notify type.
132 Deprecates the function silc_server_send_new_channel_user.
134 * Added silc_server_send_notify_leave to send LEAVE notify type.
135 Deprecates the function silc_server_send_remove_channel_user.
137 * Added silc_server_send_notify_cmode and
138 silc_server_send_notify_cumode to send CMODE and CUMODE notify
139 types. Deprecates the silc_server_send_set_mode function.
141 * Added SERVER_SIGNOFF notify type to indicate that server has
142 quit. This means that all clients on the channel from that
143 server will drop. This can be also used when netsplit happens.
145 Deprecated REMOVE_ID packet type since it is not needed anymore
148 Added silc_server_send_notify_server_signoff to send the
149 SERVER_SIGNOFF notify type. Deprecates the function
150 silc_server_send_remove_id.
152 Added also silc_server_send_notify_signoff to send the
155 * Employed the PKCS #1. It is the mandatory way to do RSA in the
156 SILC protocol from this day on. Changed the protocol
157 specification as well.
159 * Added silc_server_send_notify_topic_set to send TOPIC_SET
160 notify type. It is used between routers to notify about
161 topic changes on a channel.
163 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
166 * Partly updated the protocol specification to comply with the
167 changes now made. It is still though a bit outdated.
169 * The JOIN notify type now takes one extra argument <Channel ID>.
170 The packet used to be destined to the channel but now the
171 JOIN type may be sent as list thus it is impossible to
172 destine it to any specific channel. By adding this argument
173 it is again possible.
175 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
177 * Added CREDITS file. The CHANGES and CREDITS file will appear
178 in the distribution as well.
180 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
183 types in the server's silcd/packet_receive.c.
185 * Implemented CMODE and CUMODE to work in router environment.
187 * Fixed minor encoding and decoding buglet from the
188 lib/silccore/silcmode.c.
190 * Fixed buffer overflow from lib/silcclient/command.c in USERS
193 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
195 * Changed all SilcConfigServer* and silc_config_server* to
196 SilcServerConfig* and silc_server_config*, respectively.
199 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Associated the ID (client or server ID) to the Authentication
202 Payload to avoid any possibility of forging. Updated the
203 protocol specification and the code accordingly.
205 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
207 * The RSA key length is now save to the RsaKey context in the
208 key generation process in lib/silccrypt/rsa.c. The key length
209 is now used to figure out the maximum size of the block allowed
210 to be encrypted/signed.
212 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
213 is equivalent to the silc_mp_mp2bin but does not allocate any
216 * Changed silc_mp_mp2bin API to take length argument. If it is
217 non-zero then the buffer is allocated that large. If zero, then
218 the size is approximated using silc_mp_sizeinbase, which however
221 * Created Global RNG API which is global RNG that application can
222 initialize. After initializing, any routine anywhere in the
223 code (including library) can use RNG without allocating a new
224 RNG object. This was done to allow this sort of use of the
225 RNG in code that has no chance to allocate RNG object. All
226 applications currently allocate this and many routines in the
227 library use this. Affected file lib/silccrypt/silcrng.[ch].
229 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
230 it to use the Global RNG API.
232 * Defined Authentication Payload into protocol specification that
233 is used during SILC session to authenticate entities. It is
234 used for example by client to authenticate itself to the server
235 to obtain server operator privileges.
237 Implemented this payload into the lib/silccore/silcauth.[ch].
238 Implemented also routines for public key based authentication
239 as the new protocol specification dictates.
241 Moved definitions of different authentication methods from
242 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
244 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
245 silc_pkcs_verify and silc_pkcs_sign_with_hash and
246 silc_pkcs_verify_with_hash functions into the file
247 lib/silccrypt/silcpkcs.[ch].
249 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
251 * The client entry's userinfo pointer must be always valid.
252 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
253 will fail since it requires the userinfo. Now, the userinfo
254 is allocated as "" if actual userinfo does not exist. Actually,
255 it must exist and it is totally Ok to drop client connections
256 that does not announce the userinfo. However, we will make
257 this workaround for now.
259 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
260 to return the remote port by socket.
262 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
265 SILC_SERVER_PENDING_EXEC and added an new macro
266 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
267 data or when error occurs while processing the pending command.
269 Added new argument `destructor' into silc_server_command_pending
270 and to the SilcServerCommandPending object. This destructor is
271 now called after calling the pending callback or if error occurs
272 immediately. If error occurs the actual pending callback won't
273 be called at all - only the destructor. The destructor may be
274 NULL if destructor is not needed.
276 All this applies for client library code as well. Similar
277 changes were made there as well for the pending commands.
279 In the client, the application must now allocate the
280 SilcClientCommandContext with the silc_client_command_alloc
283 * Added reference counter to the SilcServerCommandContext. Added
284 function silc_server_command_alloc and silc_server_command_dup
287 Same type of functions added to the client library for the same
290 * Removed the cmd_ident from IDListData away since it is now
291 global for all connections. It is the command identifier used
292 in command sending and with pending commands. The affected file
295 * Added reference counter to the SilcSocketConnection objecet to
296 indicate the usage count of the object. The object won't be
297 freed untill the reference counter hits zero. Currently only
298 server uses this, and client ignores it. The client must be
299 set to use this too later. The affected files are
300 lib/silccore/silcsockconn.[ch]. Added also the function
301 silc_socket_dup to increase the reference counter.
303 This was mainly added because it is possible that the socket
304 is removed underneath of pending command or other async
305 operation. Now it won't be free'd and proper DISCONNECTING
306 flags, etc. can be set to avoid sending data to connection that
307 is not valid anymore.
309 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
310 the connection. After that it sets SILC_SET_DISCONNECTED.
311 It is, however, possible that the socket data is not still freed.
312 The silc_server_packet_process now checks that data is not
313 read or written to connection that is DISCONNECTED. The socket
314 get's freed when the reference counter hits zero.
316 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Changed the client operation API: channel_message operation's
319 `sender' is now the client entry of the sender, not the nickname
320 and the `channel' is the channel entry, not the channel name.
322 In the private_message operation the `sender' is now also the
323 client entry of the sender not the nickname.
325 Affected file is lib/silcclient/ops.h and all applications
326 using the client operations.
328 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Moved the calling of ops->connect() from connect_to_server_final
331 into receive_new_id functin since that is the point when the
332 client is actually allowed to send traffic to network. The
333 affected file is lib/silcclient/client.c.
335 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
337 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
338 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
339 (if needs broadcasting) instead of broadcasting the packets one
340 by one which would make a burst in the network traffic.
342 * Added `broadcast' argument to the functions in silcd/server.[ch]
343 silc_server_create_new_channel[_with_id] to indicate whether
344 to send New Channel packet to primary router.
346 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Added new function into the silcd/server.[ch] files:
349 silc_server_create_new_channel_with_id to create new channel with
350 already existing Channel ID.
352 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
353 lib/silccore/silcpacket.h. This packet is used t send list of
354 Set Mode payloads inside one packet. Server uses this to set
355 the modes for the channels and clients on those channels, that it
356 announced to the router when it connected to it. The protocol
357 specification has been updated accordingly.
359 * The silc_server_new_channel did not handle the packet coming
360 from normal server as it normally does not send that. However,
361 when it announces its channels it does send it. Implemented
362 the support for that.
364 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
365 into the file lib/silccore/id.h.
367 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Fixed memory leaks in the functions silc_idlist_del_client,
370 silc_idlist_del_channel and silc_idlist_del_server in the file
371 silcd/idlist.c. All of those leaked like a sieve.
373 * Fixed some small memory leaks in the client's function
374 silc_client_notify_by_server.
376 * Added functions into silcd/server.c: silc_server_announce_clients,
377 silc_server_announce_channels and silc_server_announce_server.
378 These functions are used by normal and router server to announce
379 to its primary router about clients, channels and servers (when
380 router) that we own. This is done after we've connected to the
383 These functions effectively implements the following packet types:
384 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
385 and SILC_PACKET_NEW_ID_LIST.
387 * Added new functions into the silcd/packet_receive.[ch]:
388 silc_server_new_id_list, silc_server_new_channel_list and
389 silc_server_new_channel_user_list to handle the incoming
390 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
392 * Added support of changing Channel ID in the function
393 silc_server_replace_id. If the server that announces a channel
394 to the router already exists in the router (with same name but
395 with different Channel ID), router is responsible to send
396 Replace ID packet to the server and force the server to change
397 the Channel ID to the one router has.
399 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
400 client that the Channel ID has been changed by the router. The
401 normal server sends this to the client. Client must start using
402 the new Channel ID as the channel's ID.
404 Implemented handling of this new type into lib/silcclient/client.c
405 into the function silc_client_notify_by_server.
407 * Added new function silc_idlist_replace_channel_id into the files
408 silcd/idlist.[ch] to replace the Channel ID.
410 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Call silc_server_command_identify_check always when processing
413 the IDENTIFY command in silcd/command.c
415 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
418 send keepalive packets. The packet can be sent by clients,
421 Added function silc_socket_set_heartbeat into the file
422 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
423 If not set, the heartbeat is not performed. The actual
424 heartbeat is implemented in the low level socket connection
425 library. However, application is responsible of actually
428 Added silc_server_send_heartbeat to send the actual heartbeat
429 packet into silcd/packet_send.[ch]. Server now performs
430 keepalive with all connections.
432 * Added silc_task_get_first function into lib/silcutil/silctask.c
433 to return the timeout task with shortest timeout. There was a bug
434 in task unregistration that caused problems. TODO has been
435 updated to include that task system must be rewritten.
437 * The client library will now resolve the client information when
438 receiving JOIN notify from server for client that we know but
439 have incomplete information.
441 * Rewrote parts of silc_server_remove_from_channels and
442 silc_server_remove_from_one_channel as they did not remove the
443 channel in some circumstances even though they should've.
445 * Encryption problem encountered in server:
447 The LEAVE command used to send the Channel Key packet to the
448 router immediately after generating it. However, the code
449 had earlier sent Remove Channel user packet but not immediately,
450 ie. it was put to queue. The order of packets in the router
451 was that Channel Key packet was first and Remove Channel User
452 packet was second, even though they were encrypted in the
453 reverse order. For this reason, MAC check failed. Now, this
454 is fixed by not sending the Channel Key packet immediately but
455 putting it to queue. However, this is more fundamental problem:
456 packets that are in queue should actually not be encrypted
457 because packets that are sent immediately gets encrypted
458 actually with wrong IV (and thus MAC check fails). So, packets
459 that are in queue should be encrypted when they are sent to
460 the wire and not when they put to the queue.
462 However, the problem is that the current system has not been
463 designed to work that way. Instead, the packet is encrypted
464 as soon as possible and left to the queue. The queue is then
465 just purged into wire. There won't be any fixes for this
466 any time soon. So, the current semantic for packet sending
469 o If you send packet to remote host and do not force the send
470 (the packet will be in queue) then all subsequent packets to the
471 same remote host must also be put to the queue. Only after the
472 queue has been purged is it safe again to force the packet
475 o If you send all packets immediately then it safe to send
476 any of subsequent packets through the queue, however, after
477 the first packet is put to queue then any subsequent packets
478 must also be put to the queue.
480 Follow these rules and everything works fine.
482 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Added new function silc_server_remove_clients_by_server to
485 remove all client entries from ID list when the server connection
486 is lost. In this case it is also important to invalidate all
487 client entires as they hold the invalid server entry. This
488 fixes fatal bug when server has lost connection and will reconnect
491 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Made some sanity checks to silc_server_daemonise like to check
494 whether the requested user and group actually exists.
496 * Added sanity check to SKE's silc_ske_responder_finish to check
497 that the public and private key actually is valid.
499 * Invalidate the client's nickname when receiving Replace ID
500 packet and the Client ID is being replaced. This means that the
501 server will query the nickname if someone needs it (client)
504 * Sort the ID Cache in client library when the ID Cache data
505 has changed (needs sorting).
507 * Do not allow for SILC client to create several connections to
508 several servers. The client does not support windows right now
509 and generating multiple connections causes weird behaviour.
511 Irssi-silc client does support windows and can handle several
512 connections without problems, see: www.irssi.org and SILC plugin.
514 * Fixed some places where client was added to the IDList. The
515 rule of thumb is following (in order to get everything right):
516 If the client is directly connected local client then the
517 `connection' argument must be set and `router' argument must be
518 NULL to silc_idlist_add_client function. If the client is not
519 directly connected client then the `router' argument must
520 bet set and the `connection' argument must be NULL to the
521 silc_idlist_add_client function.
523 * The funtion silc_server_packet_send_local_channel actually did
524 not check whether the client was locally connected or not. It
525 does that now. Fixed a bug related to LEAVE command.
527 * Fixed Remove Channel User payload parsing bug in server's
528 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
530 * The server's silc_server_save_channel_key now checks also the
531 global ID list for the channel as it might not be in the local
532 list. Fixed a bug related to LEAVE command.
534 * Is this the end of the [<unknown>] buglet that has been lurking
535 around for a long time? A little for loop fix in server's
536 silc_server_command_whois_parse that is used by both IDENTIFY
537 and WHOIS command. At least, this was a clear bug and a cause
538 of one type of [<unknown>] buglet.
540 * WHOIS and IDENTIFY commands call the function
541 silc_server_command_[whois/identify]_check function even if
542 we are not router server.
544 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
546 * Added --with-gmp configuration option. If set the GMP
547 is always compiled in the SILC source tree. If not set then
548 it is checked whether the system has the GMP3 installed. If
549 it has then the GMP won't be compiled (the system's headers
550 and library is used), if it doesn't have it then the GMP is
551 compiled in the SILC source tree.
553 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
555 * Changed RSA private exponent generation to what PKCS #1
556 suggests. We try to find the smallest possible d by doing
557 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
558 not security fix but optimization.
560 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Added new config entry [Identity] to fork the server and run
563 it as specific user and group. A patch from Bostik.
565 * Imported Dotconf configuration library into lib/dotconf.
566 This will be used to create the SILC configuration files later.
567 It will appear in the distsribution after this commit.
569 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * A big code auditing weekend happening. Auditing code for
572 obvious mistakes, bugs and errors. Also, removing any code
575 Removed files for being obsolete:
577 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
578 inline in the file lib/silcutil/silcbuffer.h)
580 o lib/silcutil/silcbufutil.c (the header has inline versions)
582 Changed code to fix possible error conditions:
584 o The buffer formatting routines now check that the destination
585 buffer really has enough space to add the data. This applies for
586 both buffer formatting and unformatting
587 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
588 unformatting was changed to accomodate following rules:
589 XXX_*STRING_ALLOC will allocate space for the data into the pointer
590 sent to the function while XXX_*STRING will not allocate or copy
591 the data into the buffer. Instead it sets the pointer from the
592 buffer into the pointer sent as argument (XXX_*STRING used to
593 require that the pointer must be allocated already). This change
594 makes this whole thing a bit more consistent and more optimized
595 (note that the data returned in the unformatting with XXX_*STRING
596 must not be freed now). The routines return now -1 on error.
598 o Tried to find all code that use buffer_format and buffer_unformat
599 and added return value checking to prevent formatting and
600 especially unformatting errors and possible subsequent fatal
603 o Changed ske->x and ske->KEY to mallocated pointers in
604 lib/silcske/silcske.h. Fixed possible data and memory leak.
606 o Added return value checking to all *_parse* functions. Fixed
607 many memory leaks as well.
609 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
610 so that buffer overflows would not happen. All code now also
611 checks the return value as it can fail.
613 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Added reconnection support to server if the normal server looses
616 its connection to the router (for example if router is rebooted).
617 The server performs normal reconnection strategy implemented
618 to the server. Affected file silcd/server.c.
620 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
622 * Added new packet type SILC_PACKET_SET_MODE that is used to
623 distribute the information about changed modes (for clients,
624 channels and clients channel modes) to all routers in the
625 network. Updated the protocol specification accordingly.
627 Added functions into silcd/packet_send.c and
628 silcd/packet_receive.c: silc_server_send_set_mode,
629 silc_server_set_mode.
631 Added new files silcmode.[ch] into lib/silccore that implements
632 the encoding and decoding of Set Mode Payload. Added new type
633 SilcSetModePayload. Moved the definitions of different modes
634 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
636 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Oops, a little mistake in server's connection authentication
639 protocol. The protocol is not ended with FAILURE but with
640 SUCCESS if the authentication is Ok. :) Affected file is
643 * Implemented NICK_CHANGE notify handling in server in the file
644 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
645 the local clients on the channel. After the changing nickname
646 in router environment snhould work and the [<unknown>] nickname
647 should appear no more.
649 The silc_server_replace_id function that receives the Replace ID
650 payload now sends the NICK_CHANGE notify type also in the file
651 silcd/packet_receive.c
653 * Changed WHOIS and IDENTIFY command to support the maximum amount
654 of arguments defined in protocol specs (3328 arguments). This
655 fixed a bug that caused problems when there were more than three
658 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
660 * Added extra parameter, command identifier, to the
661 silc_client_send_command so that explicit command identifier
664 Changed that ID list routines uses specific command identifier
665 when sending WHOIS/IDENTIFY requests to the server so that they
666 can be identified when the reply comes back.
668 Affected files lib/silcclient/command.[ch],
669 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
671 * Added `sender' argument to silc_server_packet_send_to_channel
672 to indicaet the sender who originally sent the packet to us
673 that we are now re-sending. Ignored if NULL. Affected file
674 silcd/packet_send.[ch].
676 * Added some server statistics support in silcd/server_internal.h
677 SilcServerStatistics structure and around the server code. Also
678 send some nice statistics information when client is connecting
681 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Fixed channel ID decoding in server's JOIN command reply in
684 silcd/command_reply.c
686 * Fixed braodcasting of replace ID payload to not to send it if
687 we are standalone server in silcd/packet_receive.c.
689 * Fixed all channel message sending routines to not to send
690 packets to clients that has router set, since they are routed
691 separately in the same function earlier. Affects file
692 silcd/packet_send.c and all channel packet sending functions.
694 * In USERS reply, res_argv[i] are not allocated, the table
695 is allocated. Thus changed that free the table, not its
698 * In server's whois_check and identify_check if the client is
699 locally connected do not send any WHOIS commands - they are not
702 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Fixed some minor bugs in client when sending WHOIS command. The
705 arguments was in wrong order.
707 * Removed statis function add_to_channel from server in
708 silcd/command.c that was previously used with the joining but
711 * Tested USERS command in router environment successfully with two
712 routers, two servers and two clients.
714 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Reorganized the USERS command and command reply in client library
717 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
718 When the command is given by user we register a pending command
719 callback that will reprocess the command after the reply has been
720 received from the server. When reprocessing the packet we then
721 display the information. Thus, the USERS information is displayed
722 now in the command callback instead of in the command reply
723 callback. The processing of the command is same as previously
724 when server has sent the command reply in the JOINing process.
726 * Added to USERS command in silcd/command_reply.c to join the client,
727 we didn't use to know about, to the channel after we've created
728 a client entry for it. Also, for clienet we did know already still
729 check whether it is on the channel or not and add it if not.
731 * Removed silc_server_command_join_notify as the function and its
734 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Changed the client's pending command handling to the same as the
737 server's pending command handling. It is also now possible to
738 execute command reply functions from other command reply
739 function as the function callbacks for commands and command
740 replies are one and same. The pending commands are not static
741 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
742 in client connection context. Thus, pending commands are server
743 connection specific as it is convenient.
745 Changed the function silc_client_command_pending and
746 silc_client_command_pending_del and added new function
747 silc_client_command_pending_check. Removed the
748 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
751 * Added cmd_ident, current command identifier, to the client
752 connection context in lib/silcclient/client.h to keep track on
753 command identifiers used in command sending. Client's command reply
754 function handling now supports the mandatory command identifiers.
756 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
757 funtions in client to fully support pending command callbacks.
759 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
760 as one of the arguments to the application in the command reply
763 * NOTE: The FORWARDED flag is depracated. It used to be depracated
764 before first releasing SILC but came back. Now it is removed again
765 and should come back nomore. The FORWARDED flag was used only
766 by the JOINing procedure by forwarding the command packet to router.
767 Now, the JOINing procedure has been changed to more generic (due
768 to various router environment issues) and FORWARDED is not needed
769 anymore for anything. The protocol specification is yet to be
772 Now, removed silc_server_packet_forward from server and the flag
773 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
775 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
777 * Renamed NAMES command to USERS command. The NAMES was named that
778 due to historical reasons. Now it is renamed. Also, rewrote
779 parts of the USERS command. The nickname list is not sent anymore
780 by the server. Only Client ID and mode lists are sent in the USERS
781 command. Changed this also to the protocol specification.
783 The client now resolves the names and stuff after it receives
784 the USERS list from the server when joining to the channel.
786 * WHOIS and IDENTIFY commands has been changed to support multiple
787 Client ID's per command. One can now search for multiple users
788 in the network by sending only one WHOIS or IDENTIFY command.
789 Changed the code and the protocol specifications.
791 * Removed silc_server_command_identify_parse and changed that IDENTIFY
792 uses silc_server_command_whois_parse to parse the request. */
794 * If normal server, do not parse the WHOIS and IDENTIFY requests
795 before sending it to the router. Saves some time.
797 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Fixed JOIN command on client library. Wrong number of arguments
800 used to crash the client.
802 * Added silc_server_channel_has_global function to check whether
803 channel has global users or not.
805 * Added silc_server_channel_has_local function to check whether channel
806 has locally connected clients on the channel.
808 * The silc_server_remove_from_one_channel now checks whether the
809 channel has global users or not after given client was removed from
810 the channel. It also checks whether the channel has local clients
811 on the channel anymore. If it does not have then the channel entry
812 is removed as it is not needed anymore.
814 * The silc_server_notify now checks on JOIN notify whether the joining
815 client is one of locally connected or global. If it is global then
816 the channel has now global users on the channel and that is marked
817 to the channel entry. Also, it now saves the global client to
818 global list who is joining and JOINs it to the channel. This is
819 for normal server, that is.
821 Changed silc_server_send_notify_on_channel,
822 silc_server_packet_relay_to_channel and
823 silc_server_packet_send_to_channel check if we are normal server
824 and client has router set (ie. global client) do not send the
825 message to that client, as it is already routed to our router.
827 * Implemented LEAVE notify type handling in silc_server_notify
830 * Tested LEAVE command in router environment successfully. Tested
831 with two routers, two servers and two clients.
835 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
837 * Implemented SIGNOFF notify type handling in silc_server_notify
840 * silc_server_remove_id now removes the client entry from all channels
841 it has joined and thusly sends SIGNOFF notify type.
843 * Rewrote the NAMES list generation in server by removing two excess
844 loops. The lists are created now inside one loop.
846 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * silc_server_remove_channel_user checks now also global list
849 for channel and client.
851 * silc_server_new_channel_user checks now both local and global
852 list for channel and client. Fixed a bug in client id decoding.
853 Used to decode wrong buffer.
855 * silc_server_channel_message checks now both local and global
856 list for channel entry.
858 * Tested channel joining (hence JOIN) in router environment
859 successfully. Tested with two routers, two servers and two
862 * Tested channel message sending in router environment successfully.
864 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Added silc_server_save_channel_key into server.[ch] to save the
867 received channel key in Channel Key payload processing. It is
868 also used in JOIN command reply handling.
870 Equivalent function silc_client_save_channel_key added into
871 client.[ch] into client library.
873 * Changed JOIN command reply to send information whether the channel
874 was created or not (is existing already) and the channel key
875 payload. Changed protocol specs accordingly.
877 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
878 the request was sent by ID and not by nickname. Crashed on
881 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
883 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
884 now correctly save the received data.
886 * silc_server_free_sock_user_data now notifies routers in the
887 network about entities leaving the network.
889 At the same time implemented functions silc_server_remove_id
890 and silc_server_send_remove_id to receive and send REMOVE_ID
891 packets. The packet is used to notify routers in the network
892 about leaving entities. The ID removed will become invalid in
895 * Added function silc_idlist_del_server into server. Removes and
896 free's server entry from ID list.
898 * silc_server_private_message function now checks, if we are router,
899 that the destination ID really is valid ID, naturally.
901 * In router when NEW_ID packet is received (for new client) the
902 hash of the Client ID is saved in the ID Cache but the
903 client->nickname is set to NULL, instead of putting the hash
906 IDENTIFY command now also checks that client->nickname must be
907 valid. If it is not if will request the data from the server who
908 owns the client. Added new function
909 silc_server_command_identify_check.
911 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
912 to set the command to already allocated Command Payload.
914 * Tested private message sending in router environment with two
915 routers, two servers and two clients. Fixed minor bugs and now
918 * Fixed segfault from client's NAMES command. Used to crash if
921 * Forwarded packets must not be routed even if it is not destined
922 to the receiver. Changed server code comply with this.
924 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Added `require_reverse_mapping' boolean value to ServerParams
927 structure. If TRUE (not default) the server will require that
928 the connecting host has fully qualified domain name.
930 If the reverse mapping is not required and hostname could not be
931 found the IP address is used as hostname.
933 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Implemented version string checking to both client and server.
936 The check is incomplete currently due to the abnormal version
937 strings used in development version of SILC.
939 * Changed all command functions in server to use the new
942 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Changed char *data to unsigned char *data in ID Cache system to
945 support binary data as ID Cache data. Changed code to support
946 binary data in lib/silccore/idcache.c.
948 * Renamed silc_server_packet_relay_command_reply to
949 silc_server_command_reply as it is normal packet receiving
950 function. Rewrote the function to accept command replys for
951 servers and not only for clients.
953 * Mark remote router always as registered server if we are connecting
954 to it. Otherwise, commands sent by the router to us are ignored.
956 * All ID List find routines now returns the ID Cache Entry pointer
957 as well if requested.
959 * WHOIS command works now in router environment, tested with two
960 routers, two servers and two clients.
962 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
963 in router environment (as it is almost equivalent to WHOIS) but
964 hasn't been tested thoroughly. Added new functions:
966 silc_server_command_identify_parse
967 silc_server_command_identify_send_reply
968 silc_server_command_identify_from_client
969 silc_server_command_identify_from_server
971 * Disabled route cache adding because adding two different ID's with
972 same IP replaces the old cache entry thus giving wrong route.
973 The entry->router->connection is always the fastest route anyway
974 so route cache may not be needed. Of course, new routes maybe
975 established after receiving the ID when the entry->router->connection
976 might not be anymore the most optimal.
978 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Add route cache for received ID for fast routing.
982 * Added silc_server_packet_route to route received packet on router
983 that is not destined to us.
985 * Renamed silc_server_get_route to silc_server_route_get.
987 * Added id_string and id_string_len fields into SilcServer to
988 include encoded ServerID for fast comparing without excess
989 encoding of the ID's.
991 * Cleaned up WHOIS command on server side. Added following static
994 silc_server_command_whois_parse
995 silc_server_command_whois_check
996 silc_server_command_whois_send_reply
997 silc_server_command_whois_from_client
998 silc_server_command_whois_from_server
1000 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1001 arguments in command replies. All command functions should be
1002 updated to use this macro.
1004 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Minor typo fixes on command reply handling on server.
1008 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Added silc_server_command_add_to_channel internal routine to add
1011 the client to the channel after router has created the channel and
1012 sent command reply to the server.
1014 * Added generic silc_server_send_command to send any command from
1017 * Use static buffer with ID rendering instead of duplicating data.
1019 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1021 * Fixed a channel user mode bug when joining to a channel server gave
1022 everybody channel founder rights, oops.
1024 * We mark ourselves as the router of the incoming server connection
1025 if we are router ourselves. This way we can check in some packet
1026 sending functions whether it is locally connected server. For
1027 incoming router connections we put NULL.
1029 * For router sending packets locally means now always sending the
1030 packet cell wide; to local clients and local servers. For normal
1031 server sending packet locally means sending it to only local
1034 * Fixed the JOIN command to really work in router environment. If the
1035 channel is created it is always created by the router. Router is
1036 also responsible of making the initial joining to the channel,
1037 sending JOIN notify to the sending server and distributing
1038 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1039 does not exist server doesn't do anything else but forward the
1040 command to the router which performs everything.
1042 * Added silc_server_send_channel_key function to send the Channel Key
1045 * Added silc_server_create_channel_key to create new channel key. The
1046 channel key is now re-generated everytime someone joins or leaves
1047 a channel, as protocol dictates. Note: channel->key_len is the
1050 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1053 packet_receive.[ch] to separate packet sending and receiving
1054 routines. The server.[ch] now includes everything else including
1055 actual packet processing (writing and reading data) and other
1058 Renamed silc_server_private_message_send_internal to
1059 silc_server_send_private_message. The routine is still though
1060 used only to relay private messages as server does not send
1061 private messages itself.
1063 Renamed silc_server_new_channel to silc_server_create_new_channel
1064 and added new function sicl_server_new_channel that handles the
1065 incoming New Channel packet. Added also new sending function
1066 silc_server_send_new_channel to send New Channel Payload.
1068 * Added new function silc_server_notify to process incoming notify
1069 packet to the server/router. Server may then relay the notify
1070 to clients if needed.
1072 * Added new function silc_server_new_channel_user to process incoming
1073 New Channel User packet. Router will redistribute the packet and
1074 send JOIN notify to its local clients and locally connected servers
1075 if needed. Normal server will send JOIN notify to its local client
1076 on same channel when received this packet. Added also corresponding
1077 sending function silc_server_send_new_channel_user to sent the
1080 * Added boolean route argument to send_notif_to_channel and
1081 packet_send_to_channel functions to attempt to route the packet
1082 if it is TRUE and send only locally if it is FALSE.
1084 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * silc_server_replace_id now broadcasts the received replace ID
1087 packet if it is not broadcast packet already. The router must
1088 broadcast to inform other routers about changed ID.
1090 * Added backpointer to server's router into SilcServer context in
1091 silcd/server_internal.h.
1093 * Fixed silc_server_packet_broadcast to send correct broadcast
1096 * The channel key is now distributed to the local client as soon
1097 as it is received from the router (in router environment) so that
1098 no other packet may be sent for the channel until client has
1101 * silc_server_remove_channel_user now broadcasts the received
1102 Remove Channel User packet if it is not broadcast packet already.
1103 The router must broadcast to inform other routers about removed
1106 * Added users field into SilcPacketContext that is a reference count
1107 of the context. One can increase the reference count by calling
1108 silc_packet_context_dup which is now changed to just increase the
1109 reference count instead of duplicating the data. The reference
1110 count is decresed by calling silc_packet_context_free that will
1111 free the data after the reference count hits zero.
1113 For now on the packet context and everything allocated into it
1114 (including the raw packet from network) must be freed by calling
1115 the new silc_packet_context_free function. Added also new function
1116 silc_packet_context_alloc that must be used now to allocate the
1117 context. This also means that if a routine is asynchronous from
1118 silc_[client/server]_packet_parse_type the packet context must
1119 be duplicated by calling silc_packet_context_dup. Otherwise it
1120 gets free'd after silc_[client/server]_packet_parse_type returns.
1121 Also, one must remember that if packet is duplicated then its
1122 reference count must be decresed by calling the free function as
1123 many times as it was duplicated.
1125 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1126 from both client and server.
1128 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Made joining to a channel working in router environment.
1132 * Cleaned up JOIN command on server side and create function
1133 silc_server_command_join_channel internal routine to make the
1136 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1138 * Changed silc_command_pending list to SilcDList. Also, added
1139 `ident' field to SilcServerCommandPending structure to identify
1140 the reply and to call correct callback.
1142 Added silc_server_command_pending_check function to replace the
1143 corresnponding macro. The silc_command_pending list is not
1146 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1147 to set identifier to previously allocated Command Payload. It
1148 is used to set identifier for command when resending Command
1151 * Added silc_command_payload_encode_payload to encode Command
1152 Payload buffer from SilcCommandPayload structure.
1154 * Added silc_argument_payload_encode_payload to encode Argument
1155 payload buffer from SilcArgumentPayload structure.
1157 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1159 * Changed WHOIS command to support router connection on server side.
1160 The whois request is always sent to router unless the server is
1161 standalone server. After server has received the reply from the
1162 router will it send the reply to the client.
1164 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1165 broadcast received broadcast packet. The function is used only
1166 by router. The broadcast packet is always sent to the router's
1169 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1170 render given ID to printable string, for log files for example.
1172 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * Made basic router to router connections working. At least they
1175 can now connect to each other but nothing really works the way
1176 they are supposed - yet.
1178 * Added new initiator token to RouterConnection configuration
1179 file in silcd/serverconfig.[ch]. It is used to tell whether we
1180 are the initiator to the remote router or whether we'll expect
1181 the other end to connect.
1183 * Moved registering of listener task to silc_server_init, hence
1184 the server starts listenning as soon as it is run, even if it
1185 does not have connections to other routers. Let's see how well
1188 * Changed default connection retry timeouts for more suitable in
1191 * Removed cipher and such arguments from silc_idlist_add_client
1192 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1193 Added new function silc_idlist_add_data to add the keys and stuff
1196 * Added SilcIDListData structure and added it to SilcClientEntry
1197 and SilcServerEntry as their first field in the structure. This
1198 way we can explicitly cast the ID entries to the SilcIDListData
1199 structure and get common data for the entries. In past, we had
1200 to first check what type of connection it is and then cast it to
1201 correct ID entry type. Now, we can directly cast the opaque
1202 pointer to the SilcIDListData (no matter what ID entry it actually
1203 is) and get the data needed.
1205 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1208 in some circumstances even if threre were timeout tasks, though not
1209 IO tasks, but tasks anyway. Now fixed.
1211 * Defined SilcServerConnection structure to hold connection specific
1212 stuff about directly connected servers and routers. The definition
1213 is currently in silcd/server_internal.h. I thought about having
1214 a bit more important role fro this struct but for now it is used
1215 only when connecting to other server (or router actually).
1217 * Added connecting retry support in server when connecting to
1218 router(s). The retry feature implement exponential backoff
1219 algorithm. Also, added SilcServerParams structure to hold default
1220 parameters for server. For now, it include these retry settings
1221 and are hard coded. After server is moded to be as Silc Server
1222 Library this structure will be more important.
1224 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Changed client librarys channel->clients table to SilcList and
1227 changed code accordingly.
1229 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Changed client's channel table to SilcList and changed code
1232 accordingly. Also changed SilcChannelClientEntry to include back-
1233 pointer to the channel so that client entry can use that structure
1234 as list as well and we have fast cross-reference to the channel.
1235 This change dramatically decreased the complexity of channel
1236 handling with client entry and vice versa (removed one extra
1237 loop when searching for channel entry from many functions).
1239 * Changed server->sim from table to SilcDList and changed code
1242 * NAMES command can now be used from user interface. It will show
1243 the user list on the channel, neatly.
1245 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1246 Code now saves realname of the user if it becomes available.
1248 * Renamed configure.in to configure.in.pre and made ./prepare
1249 script to automatically add correct version string to
1250 configure.in which it creates from configure.in.pre.
1252 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * NAMES command reply now shows users mode with the nickname when
1257 * Moved silc_client_ch[u]mode[_char] functions from
1258 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1259 place sucks, they are utility functions and should be in some
1262 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1264 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1267 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added TRQ (efficient deque and list library) into lib/trq. This is
1272 a very good list library that is currently used in the SILC. Defined
1273 SilcList API over the library because I didn't like the API very
1274 much. See lib/trq/silclist.h for the API and examples of how to
1275 use the API. Fixed various places in the code to use the new
1276 SilcList API. The SilcList is meant for lists that has a structure
1277 already defined as a list. It is not suitable to add just some
1278 context to the list (in TRQ, the context is the list actually).
1280 So, I defined SilcDList that can be used for the purpose where
1281 predefined list structure does not exit. This can be used as
1282 such list. Now some context just can be added to the SilcDList.
1283 Currently this list is not used in the SILC just yet, though there
1284 are a lot places where this can replace dynamically allocated
1285 tables and I will fix these places, later, to use SilcDList.
1286 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1287 and use TRQ internally).
1289 Also fixed some annoying warning messages that the original TRQ
1290 code generated. Also minor changes to TRQ's Makefile.in.
1292 * Added support for querying by Client ID to both WHOIS and
1293 IDENTIFY commands into server, as required by the protocol.
1295 * Removed method function pointers from SilcBuffer structure. They
1296 weren't used to anything and just increased the context size for
1297 no good reason. This change also made silc_buffer_alloc and
1298 silc_buffer_free functions inline functions.
1300 * Disabled command flooding detection support until it's fixed so
1301 that it accepts commands in but does not execute them more than once
1304 * Added silc_net_localhost(), to return local hostname, into
1305 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1306 that must be initialized before calling silc_client_init.
1308 * Added new function: silc_server_send_notify_on_channels to send
1309 notify messages to all channels client has joined. It is assured
1310 that the message is sent only once per client.
1312 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1313 lib/silcutil/silcutil.[ch] as silc_format function. The new
1314 function is generic and is used by server as well, not only by
1315 the logging routines.
1317 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1318 the provided version string was not acceptable. Added new function:
1319 silc_ske_check_version into lib/silcske/silcske.h. The function
1320 must be implemented by the application (client or server) and it
1321 does not reside in the SKE library. The function checks the version
1322 string remote end sent.
1324 * Added back pointers (to opaque context and to SilcSocketConnection)
1325 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1327 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1328 duplicate packet context structure.
1330 * Changed `notify' client operation to send same arguments as client
1331 receives from server except for ID's. ID's are mapped to correct
1332 ID entry and that is returned. Also, if channel entry is not sent
1333 by server but the notify is for channel the channel entry is sent
1334 to application (otherwise application doesn't know that it is for
1335 channel (library gets it from packet's Destination ID)).
1337 * Added silc_client_remove_from_channels into client library to
1338 remove a client from all channels it has joined to. Used when
1339 received SIGNOFF notify from server. Added also new function
1340 silc_client_replace_from_channels to replace old ID entry with
1341 new ID entry on all channels. Used when received NICK_CHANGE
1344 * Fixed ID Cache list handling in silc_idlist_get_client in
1345 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1346 to get (or query) client by ID.
1348 * Updated TODO list.
1350 * Added connection authentication status message defined by the
1351 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1352 support for these into the code in client and server side.
1354 * Added generic function silc_client_send_command to send any command
1355 with variable argument list. Application should use this function
1356 to send commands if the command functions provided by the library
1357 does not suite for the application's user interface needs.
1359 * Added new `failure' client operation. Application is notified about
1360 received failure packet if client is executing a protocol. In this
1361 case the protocol's execution has failed.
1363 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1364 is required by the protocol.
1366 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1367 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1370 * Added status flag to SilcSKE object to indicate realtime status
1371 of the SKE protocol.
1373 * Application receives now exactly same command reply arguments as
1374 the library receives from server. However, if ID is received the
1375 corresponding ID entry is returned to the application (eg. Client
1376 ID is mapped to correct SilcClientEntry entry and that is returned).
1377 Changed command_reply client operation due to this change.
1379 * Changed all ID's in commands and in command replys as ID Payloads.
1380 Change affected both client and server side codes.
1382 All ID's sent in SILC network (with execption of ID's in SILC
1383 Packet header) are sent in ID Payload to support variable length
1386 * Server now notifies nick changes and notifies all clients on
1387 the channels about the new nickname (about the new Client ID,
1390 * Implemented CMODE command to change channel modes. Supports all
1391 channel modes defined by the protocol specs except ban and invite
1392 lists. (Also, private channel key mode is supported but support for
1393 setting private channel key in client is missing, thus, this mode
1394 has no effect on client side (except that server requires that the
1395 client uses private channel key and normal channel traffic does not
1398 Also, invite mode works per se, but INVITE command does not work
1399 yet correctly, so you can set channel as invite only channel but
1400 inviting clients to the channel does not work (it is yet to be
1401 thought what's the best way to do it).
1403 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1404 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1405 Implemented CUMODE command to change user's mode on the channel.
1406 Supports all modes defined by the protocol specs.
1408 * Added NAMES command reply to return users modes on the channel.
1410 * Removed unnecessary and slow ciphers from lib/silccrypt.
1412 * Set SO_KEEPALIVE option to connection sockets by default.
1414 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1416 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1417 redefined the Notify Payload into protocol specs.
1419 * Added silc_id_payload_parse_id to get ID directly from raw
1422 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1425 accept searching by Client ID as well.
1427 * Added support for LEAVE and SIGNOFF notify types in client library.
1429 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1430 to parse ID Payload from raw data.
1432 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1434 * Added flags parameter into silc_ske_assemble_security_properties
1435 function in lib/silcske/silcske.[ch].
1437 * Changed notify client operation to fit better for notify messages
1438 sent by server. The notify payload received from server is now
1439 passed to the application (after parsing it to SilcNotifyPayload).
1440 It is application's responsibility to retrieve the arguments
1441 from the payload and show the message the way it wants. The message
1442 sent by server is implementation specific.
1444 * Changed public keys to comply with the protocol specification.
1445 Old public keys are not supported anymore and are not compatible.
1447 * Removed nickname from Channel Payload as the latest draft removed
1448 it. The client must resolve the nickname from the NAMES command
1449 reply received when it joined the channel.
1451 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1453 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Fixed some errors in protocol specification drafts.
1457 * Created lib/silccore/silcnotify.c to implement Notify Payload
1458 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1459 generic payloads described by protocol specifications. The file
1460 includes implementations for ID Payload and Argument Payload.
1462 * Changed Command Payload implementation to use the new Argument
1463 Payload. Changed command_xxxx_payload to command_payload_xxxx
1464 to comply with SILC coding conventions.
1466 * Added suppport for Argument Payload handling in Notify Payload
1467 implementation as protocol requires it. Added the new support
1468 into server and client lib as well.
1470 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Added support for multiple nicknames on same channel. [n] is
1473 added locally to the nickname if there are more than one same
1474 nicknames on the channel.
1476 * Server now sends all nicknames that matched WHOIS request.
1477 Client also shows the list received from server.
1479 * Added TOPIC command to client side. User can now set and show
1480 current topic on channel.
1482 * Added MOTD command to client and server. Also, server sends the
1483 motd when client connects to the server.
1485 * Changed version strings to comply ISO 8601.
1487 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1489 * Fixed protocol error handling in client library. It should now
1490 cope even if the SKE fails for some reason.
1492 * Made new protocol specification drafts for submitting to IETF.
1494 * Implemented TOPIC command to server in silcd/command.c.
1496 * Added two new notify types into lib/silccore/silcnotify.h:
1497 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1498 notify nickname change and topic setting/change on a channel.
1500 * API change of command_reply operation in client library. The
1501 application gets now the status type received from server as well.
1503 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1505 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1507 * Cras fixed and optimized the packet handling even further and
1508 it should work now. Minor change to the prototype of function
1509 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1511 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Added new function into lib/silcutil/silcschedule.[ch]:
1514 silc_schedule_with_fd to select() a specified fd. The function
1515 returns after timeout expires or data arrives or goes. The
1516 function is used by packet routines to wait that all data is
1517 received from network.
1519 * Fixed data reading from network in lib/silccore/silcpacket.c.
1520 The code now assures that all data is read from the fd and then
1521 continues packet processing. This was a bug fix since the code
1522 used to drop some data in some circumstances.
1524 * Added new function into lib/silcclient/client.[ch]:
1525 silc_client_start_key_exchange to start key exchange after
1526 connection has been established to server. The code internally
1527 now uses this funtion but its main purpose was to provide it
1528 for applications that perform their own connecting. After
1529 application has created a connection it merely calls this
1530 function to start the key exchange between client and server.
1531 The library takes care of everything else after that.
1533 Updated also lib/silcclient/README to explain the usage of
1536 * Do not send to application information that connection has
1537 been established. Application gets notified it by connect
1540 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Applied cras's patch to add silc_schedule_one function. The
1543 function runs scheduler once and returns.
1545 * Fixed the scheduler after cras messed it up. The timeout
1546 handling works now as it's supposed to work.
1548 * Added into lib/silccore/ silcnotify.h to include notify
1549 message types support. Changed silc_server_send_notify*
1550 functions, in server.[ch], to support those new notify types.
1551 Added the support for the notify types into client library,
1552 as well. Added new notify client operation into ops.h in
1555 * Changed silc_server_packet_send_to_channel to send normal
1556 packets instead of just channel message packets. The function
1557 is now used to send the notify packets to channels. It is not
1558 used to send channel message packets anymore, as server never
1561 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1562 va_arg()s as it seems to require it nowadays. I guess, if SILC
1563 is compiled with older va_arg() the new code should work anyway.
1565 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Splitted core library. Core library (lib/silccore) includes
1568 now only SILC protocol specific core (and common) components.
1569 Created new utility library (lib/silcutil) that includes more
1570 generic purpose stuff. The stuff for util library was taken
1571 from the old core library. This was minor and easy split.
1573 * Created SILC Client Library (lib/silcclient) that includes
1574 implementation of the SILC client without user interface. This
1575 was major move from silc/ directory. The code has been changed
1576 so that it is transparent towards the user interface. The
1577 silc/ directory includes now the same user interface as before
1578 and it uses the new client library. Read lib/silcclient/README.
1579 Basicly, the client library performs everything else related
1580 to SILC except user interface handling. Also, configuration
1581 files are considered to be part of user interface and library
1582 does not handle them.
1584 This change also changed a lot of structures, function naming etc.
1585 Most important change was that SilcClientWindow object was
1586 renamed to SilcClientConnection in the client library. Created
1587 also new file lib/silcclient/ops.h. Also added new files
1588 silc/local_command.[ch] and silc/client_ops.[ch].
1590 All these changes were made to make it easier for user interface
1591 designers to create what ever user interface for the SILC client
1594 It is also expected that the server will be moved to lib
1595 directory as well and SILC Server Library will be created;
1596 sometimes in the future.
1598 * Removed Local commands from lib/silccore/silccommand.h as
1599 they are application specific and new client library does not
1600 handle any of those anymore.
1602 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1603 old client implementation in silc/.
1605 * Added support for callback functions in SILC_LOG_* macros.
1606 Application can now set its own callbacks that will be called
1607 instead of using the default functions that will always print
1608 the debug messages to stderr (or stdout). Also, debugging can
1609 now be disabled by setting silc_debug to FALSE and re-enabled by
1610 setting it to TRUE. Note, that logging will still work even
1611 if debugging is disabled.
1613 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1614 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1615 silc_log_reset_debug_callbacks.
1617 * To enable debugging in silc client one must give now -d
1618 option on command line.
1620 * Changed silc_schedule_init to automatically allocate task queues
1621 if they are not allocated before calling it.
1623 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1625 * Added GMP 3.1 into math library.
1627 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1629 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1630 a channel in SILC network. The packet is used by servers and
1631 routers to notify other routers that user has left a channel.
1632 This little feature was missing until now. Added the feature
1633 to protocol specification as well.
1635 Added functions: silc_server_send_remove_channel_user and
1636 silc_server_remove_channel_user into server.[ch].
1638 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1639 lib/silccore/silcpacket.h. However, they are not implemented
1642 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1644 * Fixed joining to a channel and sending channel messages
1645 between server and router. The channel message sending should
1646 now work inside a cell.
1648 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1650 * Fixed the private message sending between server and router.
1651 The private message sending should now work inside a cell.
1653 * Added silc_server_replace_id into server.[ch] to replace
1654 existing ID in the SILC network.
1656 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1657 and silc_idlist_replace_server_id into idlist.[ch] in server.
1659 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1661 * Fixed the server to server connections. Server can again now
1662 connect to router. Router to router connections probably does
1665 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1667 * Added dynamic protocol registering support. Now protocols can
1668 registered and unregistered on the fly. Patch by cras.
1670 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1672 * Added lib/contrib directory to hold routines that some platforms
1673 don't have but are needed by SILC.
1675 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1676 into lin/contrib to provide getopt() and getopt_long() for
1677 those who don't have it.
1679 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1681 * Added AWAY command to client. When away message is set and
1682 client receives a private message packet the client automatically
1683 replies to the sender with the away message.
1685 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1686 bug seemed to be the cause of recent problems when compiling
1689 * Added version detection support to SKE protocol specification
1690 and added the new changes to the SKE implementation as well.
1691 There were other minor changes in the SKE protocol as well.
1693 Many changes in lib/silcske/silcske.[ch] and in
1694 lib/silcske/payload.[ch].
1696 * Added ^U functionality, clear input line. Patch from cras.
1698 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Mainly small bugfixes on core library. Fixed some debugging
1701 logging and buffer overflow in silclog.c.
1703 * Updated config.sub and config.guess on the distribution tree.
1705 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1707 * Added command lagging support in server. Client may execute
1708 commands now only once in two seconds.
1710 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Optimized packet reception. MAC computation and checking is now
1713 also more optimized. A lot previously duplicated code is now
1714 used as generic by both client and server.
1716 * Fixed key pair generation in clientutil.c
1718 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Added into lib/silccore/silcbufutil.[ch] new function;
1721 silc_buffer_realloc.
1723 * Moved generic packet sending/encryption functions to
1724 lib/silccore/silcpacket.[ch] from client and server. Some
1725 rewriting of the functions.
1727 * Moved all generic packet reception/decryption functions to
1728 lib/silccore/silcpacket.[ch] from client and server. The
1729 packet processing is now much cleaner in both client and server.
1730 These were major changes in both client and server.
1732 * Created many common functions in server to do packet sending.
1733 Previously code were duplicated a lot, this has been removed
1736 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1738 * Rewrote major parts of the ID cache system. Don't know
1739 whether it is better now or not but at least the API is more
1742 * Major rewrite on ID cache stuff on client because of the ID
1743 cache API changes. Added idlist.c to client.
1745 * Also major rewrite on ID cache stuff on server as well.
1746 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1747 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1748 in hand, instead they are all put into the ID cache system now.
1749 All server_idlist_* routines uses ID cache now instead of
1750 traversing its own lists (those lists does not exist anymore).
1751 SilcIDList though still exists. Also, SilcXXXEntry's are
1754 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1756 * Finally made the SKE implementation compliant to the protocol
1757 specification. All mp integers are now binary encoded as
1758 opposed being HEX encoded.
1760 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1763 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1764 functions: silc_[encode/decode]_pem. Also added function
1765 silc_encode_pem_file to PEM encode with newlines ('\n') for
1768 * SILC public keys are now encoded either PEM or binary. Same
1769 option is for private keys as well. By default private keys
1770 are binary encoded and public keys PEM encoded. Silly HEX
1771 encoding were removed.
1773 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1774 function to create fingerprints.
1776 * Fixed a bug in SHA1; does not change the original data anymore.
1778 * Partly implemented INFO command on client and server side.
1779 Fixed CLEAR command. Changes to SERVER command; show current
1780 server(s) when giving command without arguments. Added
1781 VERSION command to client.
1783 * Added check to server that unregistered connections cannot
1784 execute commands (unless it is specificly allowed).
1786 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Fixed screen refresh.
1790 * Fixed channel joining bug from client. On some circumstances
1791 client tried to join to a channel it had already joined.
1793 * Added public key verification process into client's protocol.c.
1794 The client now verifies the public key from user and saves
1795 it into ~./silc/serverkeys/ directory.
1797 Added into: clientutil.[ch]: silc_client_verify_server_key.
1799 * Changed SKE protocol's silc_ske_initiator_finish function
1800 to accept callback function that verifies the received public
1801 key. Removed old silc_ske_verify_public_key function.
1803 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1806 silc_pkcs_private_key[_data]_set.
1808 * Made the password and public authentication more cleaner in
1809 server's protocol.c.
1811 * Removed historic and obsolete protocol `channel_auth' from
1812 both client and server.
1814 * Removed wrong way of sending command status messages from
1815 server to client in server's command.c. The old way violated
1816 protocol specification.
1818 Changes to silccore/silccommand.[ch]: removed
1819 silc_command_encode_status_payload -> not needed anymore,
1820 changed silc_command_encode_payload_va to accept extra
1821 argument on variable argument list. The argument type must
1822 now be provided to the function. Also, added new function:
1823 silc_command_encode_reply_payload_va which is same as
1824 normal command_encode_payload_va except command status type
1825 is provided as extra argument.
1827 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Added ~./silc directory handling. The directory includes the
1830 public and private keys for the client.
1832 Added silc_client_check_silc_dir, silc_client_create_identifier
1833 and silc_client_load_keys.
1835 * Implemented SILC protocol compliant public key. Added public
1836 and private key saving to and loading from files.
1838 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1839 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1840 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1841 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1842 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1844 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1845 silc_pkcs_load_[public/private]_key.
1847 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1849 * Added silc_server_get_route (route.[ch]) to get connection
1850 data for the fastest route for given ID.
1852 * Implemented INVITE command on client and server. The command
1853 were re-defined in the SILC Protocol Specification and the
1854 implementation now complies with the specification.
1856 * Implemented PING command on client and server.
1858 * Implemented NAMES command on client and server. The server side
1859 supports currently only normal server not router server yet.
1860 Some changes to NAMES definition in SILC protocol specification.
1862 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1864 * Implemented LEAVE command on client and server.
1866 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1867 again. This change was made to the protocol as well. Server
1868 should not violate the protocol specification anymore.
1870 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1873 was tested. SOCKS4 was not but should work anyway.
