1 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4 types in the server's silcd/packet_receive.c.
6 * Implemented CMODE and CUMODE to work in router environment.
8 * Fixed minor encoding and decoding buglet from the
9 lib/silccore/silcmode.c.
11 * Fixed buffer overflow from lib/silcclient/command.c in USERS
14 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
16 * Changed all SilcConfigServer* and silc_config_server* to
17 SilcServerConfig* and silc_server_config*, respectively.
20 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
22 * Associated the ID (client or server ID) to the Authentication
23 Payload to avoid any possibility of forging. Updated the
24 protocol specification and the code accordingly.
26 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * The RSA key length is now save to the RsaKey context in the
29 key generation process in lib/silccrypt/rsa.c. The key length
30 is now used to figure out the maximum size of the block allowed
31 to be encrypted/signed.
33 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
34 is equivalent to the silc_mp_mp2bin but does not allocate any
37 * Changed silc_mp_mp2bin API to take length argument. If it is
38 non-zero then the buffer is allocated that large. If zero, then
39 the size is approximated using silc_mp_sizeinbase, which however
42 * Created Global RNG API which is global RNG that application can
43 initialize. After initializing, any routine anywhere in the
44 code (including library) can use RNG without allocating a new
45 RNG object. This was done to allow this sort of use of the
46 RNG in code that has no chance to allocate RNG object. All
47 applications currently allocate this and many routines in the
48 library use this. Affected file lib/silccrypt/silcrng.[ch].
50 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
51 it to use the Global RNG API.
53 * Defined Authentication Payload into protocol specification that
54 is used during SILC session to authenticate entities. It is
55 used for example by client to authenticate itself to the server
56 to obtain server operator privileges.
58 Implemented this payload into the lib/silccore/silcauth.[ch].
59 Implemented also routines for public key based authentication
60 as the new protocol specification dictates.
62 Moved definitions of different authentication methods from
63 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
65 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
66 silc_pkcs_verify and silc_pkcs_sign_with_hash and
67 silc_pkcs_verify_with_hash functions into the file
68 lib/silccrypt/silcpkcs.[ch].
70 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
72 * The client entry's userinfo pointer must be always valid.
73 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
74 will fail since it requires the userinfo. Now, the userinfo
75 is allocated as "" if actual userinfo does not exist. Actually,
76 it must exist and it is totally Ok to drop client connections
77 that does not announce the userinfo. However, we will make
78 this workaround for now.
80 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
81 to return the remote port by socket.
83 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
86 SILC_SERVER_PENDING_EXEC and added an new macro
87 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
88 data or when error occurs while processing the pending command.
90 Added new argument `destructor' into silc_server_command_pending
91 and to the SilcServerCommandPending object. This destructor is
92 now called after calling the pending callback or if error occurs
93 immediately. If error occurs the actual pending callback won't
94 be called at all - only the destructor. The destructor may be
95 NULL if destructor is not needed.
97 All this applies for client library code as well. Similar
98 changes were made there as well for the pending commands.
100 In the client, the application must now allocate the
101 SilcClientCommandContext with the silc_client_command_alloc
104 * Added reference counter to the SilcServerCommandContext. Added
105 function silc_server_command_alloc and silc_server_command_dup
108 Same type of functions added to the client library for the same
111 * Removed the cmd_ident from IDListData away since it is now
112 global for all connections. It is the command identifier used
113 in command sending and with pending commands. The affected file
116 * Added reference counter to the SilcSocketConnection objecet to
117 indicate the usage count of the object. The object won't be
118 freed untill the reference counter hits zero. Currently only
119 server uses this, and client ignores it. The client must be
120 set to use this too later. The affected files are
121 lib/silccore/silcsockconn.[ch]. Added also the function
122 silc_socket_dup to increase the reference counter.
124 This was mainly added because it is possible that the socket
125 is removed underneath of pending command or other async
126 operation. Now it won't be free'd and proper DISCONNECTING
127 flags, etc. can be set to avoid sending data to connection that
128 is not valid anymore.
130 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
131 the connection. After that it sets SILC_SET_DISCONNECTED.
132 It is, however, possible that the socket data is not still freed.
133 The silc_server_packet_process now checks that data is not
134 read or written to connection that is DISCONNECTED. The socket
135 get's freed when the reference counter hits zero.
137 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Changed the client operation API: channel_message operation's
140 `sender' is now the client entry of the sender, not the nickname
141 and the `channel' is the channel entry, not the channel name.
143 In the private_message operation the `sender' is now also the
144 client entry of the sender not the nickname.
146 Affected file is lib/silcclient/ops.h and all applications
147 using the client operations.
149 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
151 * Moved the calling of ops->connect() from connect_to_server_final
152 into receive_new_id functin since that is the point when the
153 client is actually allowed to send traffic to network. The
154 affected file is lib/silcclient/client.c.
156 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
159 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
160 (if needs broadcasting) instead of broadcasting the packets one
161 by one which would make a burst in the network traffic.
163 * Added `broadcast' argument to the functions in silcd/server.[ch]
164 silc_server_create_new_channel[_with_id] to indicate whether
165 to send New Channel packet to primary router.
167 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
169 * Added new function into the silcd/server.[ch] files:
170 silc_server_create_new_channel_with_id to create new channel with
171 already existing Channel ID.
173 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
174 lib/silccore/silcpacket.h. This packet is used t send list of
175 Set Mode payloads inside one packet. Server uses this to set
176 the modes for the channels and clients on those channels, that it
177 announced to the router when it connected to it. The protocol
178 specification has been updated accordingly.
180 * The silc_server_new_channel did not handle the packet coming
181 from normal server as it normally does not send that. However,
182 when it announces its channels it does send it. Implemented
183 the support for that.
185 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
186 into the file lib/silccore/id.h.
188 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
190 * Fixed memory leaks in the functions silc_idlist_del_client,
191 silc_idlist_del_channel and silc_idlist_del_server in the file
192 silcd/idlist.c. All of those leaked like a sieve.
194 * Fixed some small memory leaks in the client's function
195 silc_client_notify_by_server.
197 * Added functions into silcd/server.c: silc_server_announce_clients,
198 silc_server_announce_channels and silc_server_announce_server.
199 These functions are used by normal and router server to announce
200 to its primary router about clients, channels and servers (when
201 router) that we own. This is done after we've connected to the
204 These functions effectively implements the following packet types:
205 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
206 and SILC_PACKET_NEW_ID_LIST.
208 * Added new functions into the silcd/packet_receive.[ch]:
209 silc_server_new_id_list, silc_server_new_channel_list and
210 silc_server_new_channel_user_list to handle the incoming
211 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
213 * Added support of changing Channel ID in the function
214 silc_server_replace_id. If the server that announces a channel
215 to the router already exists in the router (with same name but
216 with different Channel ID), router is responsible to send
217 Replace ID packet to the server and force the server to change
218 the Channel ID to the one router has.
220 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
221 client that the Channel ID has been changed by the router. The
222 normal server sends this to the client. Client must start using
223 the new Channel ID as the channel's ID.
225 Implemented handling of this new type into lib/silcclient/client.c
226 into the function silc_client_notify_by_server.
228 * Added new function silc_idlist_replace_channel_id into the files
229 silcd/idlist.[ch] to replace the Channel ID.
231 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
233 * Call silc_server_command_identify_check always when processing
234 the IDENTIFY command in silcd/command.c
236 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
238 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
239 send keepalive packets. The packet can be sent by clients,
242 Added function silc_socket_set_heartbeat into the file
243 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
244 If not set, the heartbeat is not performed. The actual
245 heartbeat is implemented in the low level socket connection
246 library. However, application is responsible of actually
249 Added silc_server_send_heartbeat to send the actual heartbeat
250 packet into silcd/packet_send.[ch]. Server now performs
251 keepalive with all connections.
253 * Added silc_task_get_first function into lib/silcutil/silctask.c
254 to return the timeout task with shortest timeout. There was a bug
255 in task unregistration that caused problems. TODO has been
256 updated to include that task system must be rewritten.
258 * The client library will now resolve the client information when
259 receiving JOIN notify from server for client that we know but
260 have incomplete information.
262 * Rewrote parts of silc_server_remove_from_channels and
263 silc_server_remove_from_one_channel as they did not remove the
264 channel in some circumstances even though they should've.
266 * Encryption problem encountered in server:
268 The LEAVE command used to send the Channel Key packet to the
269 router immediately after generating it. However, the code
270 had earlier sent Remove Channel user packet but not immediately,
271 ie. it was put to queue. The order of packets in the router
272 was that Channel Key packet was first and Remove Channel User
273 packet was second, even though they were encrypted in the
274 reverse order. For this reason, MAC check failed. Now, this
275 is fixed by not sending the Channel Key packet immediately but
276 putting it to queue. However, this is more fundamental problem:
277 packets that are in queue should actually not be encrypted
278 because packets that are sent immediately gets encrypted
279 actually with wrong IV (and thus MAC check fails). So, packets
280 that are in queue should be encrypted when they are sent to
281 the wire and not when they put to the queue.
283 However, the problem is that the current system has not been
284 designed to work that way. Instead, the packet is encrypted
285 as soon as possible and left to the queue. The queue is then
286 just purged into wire. There won't be any fixes for this
287 any time soon. So, the current semantic for packet sending
290 o If you send packet to remote host and do not force the send
291 (the packet will be in queue) then all subsequent packets to the
292 same remote host must also be put to the queue. Only after the
293 queue has been purged is it safe again to force the packet
296 o If you send all packets immediately then it safe to send
297 any of subsequent packets through the queue, however, after
298 the first packet is put to queue then any subsequent packets
299 must also be put to the queue.
301 Follow these rules and everything works fine.
303 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Added new function silc_server_remove_clients_by_server to
306 remove all client entries from ID list when the server connection
307 is lost. In this case it is also important to invalidate all
308 client entires as they hold the invalid server entry. This
309 fixes fatal bug when server has lost connection and will reconnect
312 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
314 * Made some sanity checks to silc_server_daemonise like to check
315 whether the requested user and group actually exists.
317 * Added sanity check to SKE's silc_ske_responder_finish to check
318 that the public and private key actually is valid.
320 * Invalidate the client's nickname when receiving Replace ID
321 packet and the Client ID is being replaced. This means that the
322 server will query the nickname if someone needs it (client)
325 * Sort the ID Cache in client library when the ID Cache data
326 has changed (needs sorting).
328 * Do not allow for SILC client to create several connections to
329 several servers. The client does not support windows right now
330 and generating multiple connections causes weird behaviour.
332 Irssi-silc client does support windows and can handle several
333 connections without problems, see: www.irssi.org and SILC plugin.
335 * Fixed some places where client was added to the IDList. The
336 rule of thumb is following (in order to get everything right):
337 If the client is directly connected local client then the
338 `connection' argument must be set and `router' argument must be
339 NULL to silc_idlist_add_client function. If the client is not
340 directly connected client then the `router' argument must
341 bet set and the `connection' argument must be NULL to the
342 silc_idlist_add_client function.
344 * The funtion silc_server_packet_send_local_channel actually did
345 not check whether the client was locally connected or not. It
346 does that now. Fixed a bug related to LEAVE command.
348 * Fixed Remove Channel User payload parsing bug in server's
349 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
351 * The server's silc_server_save_channel_key now checks also the
352 global ID list for the channel as it might not be in the local
353 list. Fixed a bug related to LEAVE command.
355 * Is this the end of the [<unknown>] buglet that has been lurking
356 around for a long time? A little for loop fix in server's
357 silc_server_command_whois_parse that is used by both IDENTIFY
358 and WHOIS command. At least, this was a clear bug and a cause
359 of one type of [<unknown>] buglet.
361 * WHOIS and IDENTIFY commands call the function
362 silc_server_command_[whois/identify]_check function even if
363 we are not router server.
365 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * Added --with-gmp configuration option. If set the GMP
368 is always compiled in the SILC source tree. If not set then
369 it is checked whether the system has the GMP3 installed. If
370 it has then the GMP won't be compiled (the system's headers
371 and library is used), if it doesn't have it then the GMP is
372 compiled in the SILC source tree.
374 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Changed RSA private exponent generation to what PKCS #1
377 suggests. We try to find the smallest possible d by doing
378 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
379 not security fix but optimization.
381 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Added new config entry [Identity] to fork the server and run
384 it as specific user and group. A patch from Bostik.
386 * Imported Dotconf configuration library into lib/dotconf.
387 This will be used to create the SILC configuration files later.
388 It will appear in the distsribution after this commit.
390 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * A big code auditing weekend happening. Auditing code for
393 obvious mistakes, bugs and errors. Also, removing any code
396 Removed files for being obsolete:
398 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
399 inline in the file lib/silcutil/silcbuffer.h)
401 o lib/silcutil/silcbufutil.c (the header has inline versions)
403 Changed code to fix possible error conditions:
405 o The buffer formatting routines now check that the destination
406 buffer really has enough space to add the data. This applies for
407 both buffer formatting and unformatting
408 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
409 unformatting was changed to accomodate following rules:
410 XXX_*STRING_ALLOC will allocate space for the data into the pointer
411 sent to the function while XXX_*STRING will not allocate or copy
412 the data into the buffer. Instead it sets the pointer from the
413 buffer into the pointer sent as argument (XXX_*STRING used to
414 require that the pointer must be allocated already). This change
415 makes this whole thing a bit more consistent and more optimized
416 (note that the data returned in the unformatting with XXX_*STRING
417 must not be freed now). The routines return now -1 on error.
419 o Tried to find all code that use buffer_format and buffer_unformat
420 and added return value checking to prevent formatting and
421 especially unformatting errors and possible subsequent fatal
424 o Changed ske->x and ske->KEY to mallocated pointers in
425 lib/silcske/silcske.h. Fixed possible data and memory leak.
427 o Added return value checking to all *_parse* functions. Fixed
428 many memory leaks as well.
430 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
431 so that buffer overflows would not happen. All code now also
432 checks the return value as it can fail.
434 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Added reconnection support to server if the normal server looses
437 its connection to the router (for example if router is rebooted).
438 The server performs normal reconnection strategy implemented
439 to the server. Affected file silcd/server.c.
441 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
443 * Added new packet type SILC_PACKET_SET_MODE that is used to
444 distribute the information about changed modes (for clients,
445 channels and clients channel modes) to all routers in the
446 network. Updated the protocol specification accordingly.
448 Added functions into silcd/packet_send.c and
449 silcd/packet_receive.c: silc_server_send_set_mode,
450 silc_server_set_mode.
452 Added new files silcmode.[ch] into lib/silccore that implements
453 the encoding and decoding of Set Mode Payload. Added new type
454 SilcSetModePayload. Moved the definitions of different modes
455 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
457 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Oops, a little mistake in server's connection authentication
460 protocol. The protocol is not ended with FAILURE but with
461 SUCCESS if the authentication is Ok. :) Affected file is
464 * Implemented NICK_CHANGE notify handling in server in the file
465 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
466 the local clients on the channel. After the changing nickname
467 in router environment snhould work and the [<unknown>] nickname
468 should appear no more.
470 The silc_server_replace_id function that receives the Replace ID
471 payload now sends the NICK_CHANGE notify type also in the file
472 silcd/packet_receive.c
474 * Changed WHOIS and IDENTIFY command to support the maximum amount
475 of arguments defined in protocol specs (3328 arguments). This
476 fixed a bug that caused problems when there were more than three
479 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Added extra parameter, command identifier, to the
482 silc_client_send_command so that explicit command identifier
485 Changed that ID list routines uses specific command identifier
486 when sending WHOIS/IDENTIFY requests to the server so that they
487 can be identified when the reply comes back.
489 Affected files lib/silcclient/command.[ch],
490 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
492 * Added `sender' argument to silc_server_packet_send_to_channel
493 to indicaet the sender who originally sent the packet to us
494 that we are now re-sending. Ignored if NULL. Affected file
495 silcd/packet_send.[ch].
497 * Added some server statistics support in silcd/server_internal.h
498 SilcServerStatistics structure and around the server code. Also
499 send some nice statistics information when client is connecting
502 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
504 * Fixed channel ID decoding in server's JOIN command reply in
505 silcd/command_reply.c
507 * Fixed braodcasting of replace ID payload to not to send it if
508 we are standalone server in silcd/packet_receive.c.
510 * Fixed all channel message sending routines to not to send
511 packets to clients that has router set, since they are routed
512 separately in the same function earlier. Affects file
513 silcd/packet_send.c and all channel packet sending functions.
515 * In USERS reply, res_argv[i] are not allocated, the table
516 is allocated. Thus changed that free the table, not its
519 * In server's whois_check and identify_check if the client is
520 locally connected do not send any WHOIS commands - they are not
523 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
525 * Fixed some minor bugs in client when sending WHOIS command. The
526 arguments was in wrong order.
528 * Removed statis function add_to_channel from server in
529 silcd/command.c that was previously used with the joining but
532 * Tested USERS command in router environment successfully with two
533 routers, two servers and two clients.
535 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
537 * Reorganized the USERS command and command reply in client library
538 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
539 When the command is given by user we register a pending command
540 callback that will reprocess the command after the reply has been
541 received from the server. When reprocessing the packet we then
542 display the information. Thus, the USERS information is displayed
543 now in the command callback instead of in the command reply
544 callback. The processing of the command is same as previously
545 when server has sent the command reply in the JOINing process.
547 * Added to USERS command in silcd/command_reply.c to join the client,
548 we didn't use to know about, to the channel after we've created
549 a client entry for it. Also, for clienet we did know already still
550 check whether it is on the channel or not and add it if not.
552 * Removed silc_server_command_join_notify as the function and its
555 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
557 * Changed the client's pending command handling to the same as the
558 server's pending command handling. It is also now possible to
559 execute command reply functions from other command reply
560 function as the function callbacks for commands and command
561 replies are one and same. The pending commands are not static
562 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
563 in client connection context. Thus, pending commands are server
564 connection specific as it is convenient.
566 Changed the function silc_client_command_pending and
567 silc_client_command_pending_del and added new function
568 silc_client_command_pending_check. Removed the
569 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
572 * Added cmd_ident, current command identifier, to the client
573 connection context in lib/silcclient/client.h to keep track on
574 command identifiers used in command sending. Client's command reply
575 function handling now supports the mandatory command identifiers.
577 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
578 funtions in client to fully support pending command callbacks.
580 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
581 as one of the arguments to the application in the command reply
584 * NOTE: The FORWARDED flag is depracated. It used to be depracated
585 before first releasing SILC but came back. Now it is removed again
586 and should come back nomore. The FORWARDED flag was used only
587 by the JOINing procedure by forwarding the command packet to router.
588 Now, the JOINing procedure has been changed to more generic (due
589 to various router environment issues) and FORWARDED is not needed
590 anymore for anything. The protocol specification is yet to be
593 Now, removed silc_server_packet_forward from server and the flag
594 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
596 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
598 * Renamed NAMES command to USERS command. The NAMES was named that
599 due to historical reasons. Now it is renamed. Also, rewrote
600 parts of the USERS command. The nickname list is not sent anymore
601 by the server. Only Client ID and mode lists are sent in the USERS
602 command. Changed this also to the protocol specification.
604 The client now resolves the names and stuff after it receives
605 the USERS list from the server when joining to the channel.
607 * WHOIS and IDENTIFY commands has been changed to support multiple
608 Client ID's per command. One can now search for multiple users
609 in the network by sending only one WHOIS or IDENTIFY command.
610 Changed the code and the protocol specifications.
612 * Removed silc_server_command_identify_parse and changed that IDENTIFY
613 uses silc_server_command_whois_parse to parse the request. */
615 * If normal server, do not parse the WHOIS and IDENTIFY requests
616 before sending it to the router. Saves some time.
618 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
620 * Fixed JOIN command on client library. Wrong number of arguments
621 used to crash the client.
623 * Added silc_server_channel_has_global function to check whether
624 channel has global users or not.
626 * Added silc_server_channel_has_local function to check whether channel
627 has locally connected clients on the channel.
629 * The silc_server_remove_from_one_channel now checks whether the
630 channel has global users or not after given client was removed from
631 the channel. It also checks whether the channel has local clients
632 on the channel anymore. If it does not have then the channel entry
633 is removed as it is not needed anymore.
635 * The silc_server_notify now checks on JOIN notify whether the joining
636 client is one of locally connected or global. If it is global then
637 the channel has now global users on the channel and that is marked
638 to the channel entry. Also, it now saves the global client to
639 global list who is joining and JOINs it to the channel. This is
640 for normal server, that is.
642 Changed silc_server_send_notify_on_channel,
643 silc_server_packet_relay_to_channel and
644 silc_server_packet_send_to_channel check if we are normal server
645 and client has router set (ie. global client) do not send the
646 message to that client, as it is already routed to our router.
648 * Implemented LEAVE notify type handling in silc_server_notify
651 * Tested LEAVE command in router environment successfully. Tested
652 with two routers, two servers and two clients.
656 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
658 * Implemented SIGNOFF notify type handling in silc_server_notify
661 * silc_server_remove_id now removes the client entry from all channels
662 it has joined and thusly sends SIGNOFF notify type.
664 * Rewrote the NAMES list generation in server by removing two excess
665 loops. The lists are created now inside one loop.
667 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
669 * silc_server_remove_channel_user checks now also global list
670 for channel and client.
672 * silc_server_new_channel_user checks now both local and global
673 list for channel and client. Fixed a bug in client id decoding.
674 Used to decode wrong buffer.
676 * silc_server_channel_message checks now both local and global
677 list for channel entry.
679 * Tested channel joining (hence JOIN) in router environment
680 successfully. Tested with two routers, two servers and two
683 * Tested channel message sending in router environment successfully.
685 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
687 * Added silc_server_save_channel_key into server.[ch] to save the
688 received channel key in Channel Key payload processing. It is
689 also used in JOIN command reply handling.
691 Equivalent function silc_client_save_channel_key added into
692 client.[ch] into client library.
694 * Changed JOIN command reply to send information whether the channel
695 was created or not (is existing already) and the channel key
696 payload. Changed protocol specs accordingly.
698 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
699 the request was sent by ID and not by nickname. Crashed on
702 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
705 now correctly save the received data.
707 * silc_server_free_sock_user_data now notifies routers in the
708 network about entities leaving the network.
710 At the same time implemented functions silc_server_remove_id
711 and silc_server_send_remove_id to receive and send REMOVE_ID
712 packets. The packet is used to notify routers in the network
713 about leaving entities. The ID removed will become invalid in
716 * Added function silc_idlist_del_server into server. Removes and
717 free's server entry from ID list.
719 * silc_server_private_message function now checks, if we are router,
720 that the destination ID really is valid ID, naturally.
722 * In router when NEW_ID packet is received (for new client) the
723 hash of the Client ID is saved in the ID Cache but the
724 client->nickname is set to NULL, instead of putting the hash
727 IDENTIFY command now also checks that client->nickname must be
728 valid. If it is not if will request the data from the server who
729 owns the client. Added new function
730 silc_server_command_identify_check.
732 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
733 to set the command to already allocated Command Payload.
735 * Tested private message sending in router environment with two
736 routers, two servers and two clients. Fixed minor bugs and now
739 * Fixed segfault from client's NAMES command. Used to crash if
742 * Forwarded packets must not be routed even if it is not destined
743 to the receiver. Changed server code comply with this.
745 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
747 * Added `require_reverse_mapping' boolean value to ServerParams
748 structure. If TRUE (not default) the server will require that
749 the connecting host has fully qualified domain name.
751 If the reverse mapping is not required and hostname could not be
752 found the IP address is used as hostname.
754 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Implemented version string checking to both client and server.
757 The check is incomplete currently due to the abnormal version
758 strings used in development version of SILC.
760 * Changed all command functions in server to use the new
763 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Changed char *data to unsigned char *data in ID Cache system to
766 support binary data as ID Cache data. Changed code to support
767 binary data in lib/silccore/idcache.c.
769 * Renamed silc_server_packet_relay_command_reply to
770 silc_server_command_reply as it is normal packet receiving
771 function. Rewrote the function to accept command replys for
772 servers and not only for clients.
774 * Mark remote router always as registered server if we are connecting
775 to it. Otherwise, commands sent by the router to us are ignored.
777 * All ID List find routines now returns the ID Cache Entry pointer
778 as well if requested.
780 * WHOIS command works now in router environment, tested with two
781 routers, two servers and two clients.
783 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
784 in router environment (as it is almost equivalent to WHOIS) but
785 hasn't been tested thoroughly. Added new functions:
787 silc_server_command_identify_parse
788 silc_server_command_identify_send_reply
789 silc_server_command_identify_from_client
790 silc_server_command_identify_from_server
792 * Disabled route cache adding because adding two different ID's with
793 same IP replaces the old cache entry thus giving wrong route.
794 The entry->router->connection is always the fastest route anyway
795 so route cache may not be needed. Of course, new routes maybe
796 established after receiving the ID when the entry->router->connection
797 might not be anymore the most optimal.
799 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Add route cache for received ID for fast routing.
803 * Added silc_server_packet_route to route received packet on router
804 that is not destined to us.
806 * Renamed silc_server_get_route to silc_server_route_get.
808 * Added id_string and id_string_len fields into SilcServer to
809 include encoded ServerID for fast comparing without excess
810 encoding of the ID's.
812 * Cleaned up WHOIS command on server side. Added following static
815 silc_server_command_whois_parse
816 silc_server_command_whois_check
817 silc_server_command_whois_send_reply
818 silc_server_command_whois_from_client
819 silc_server_command_whois_from_server
821 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
822 arguments in command replies. All command functions should be
823 updated to use this macro.
825 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Minor typo fixes on command reply handling on server.
829 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
831 * Added silc_server_command_add_to_channel internal routine to add
832 the client to the channel after router has created the channel and
833 sent command reply to the server.
835 * Added generic silc_server_send_command to send any command from
838 * Use static buffer with ID rendering instead of duplicating data.
840 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
842 * Fixed a channel user mode bug when joining to a channel server gave
843 everybody channel founder rights, oops.
845 * We mark ourselves as the router of the incoming server connection
846 if we are router ourselves. This way we can check in some packet
847 sending functions whether it is locally connected server. For
848 incoming router connections we put NULL.
850 * For router sending packets locally means now always sending the
851 packet cell wide; to local clients and local servers. For normal
852 server sending packet locally means sending it to only local
855 * Fixed the JOIN command to really work in router environment. If the
856 channel is created it is always created by the router. Router is
857 also responsible of making the initial joining to the channel,
858 sending JOIN notify to the sending server and distributing
859 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
860 does not exist server doesn't do anything else but forward the
861 command to the router which performs everything.
863 * Added silc_server_send_channel_key function to send the Channel Key
866 * Added silc_server_create_channel_key to create new channel key. The
867 channel key is now re-generated everytime someone joins or leaves
868 a channel, as protocol dictates. Note: channel->key_len is the
871 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
873 * Splitted server.[ch] finally. Created now packet_send.[ch] and
874 packet_receive.[ch] to separate packet sending and receiving
875 routines. The server.[ch] now includes everything else including
876 actual packet processing (writing and reading data) and other
879 Renamed silc_server_private_message_send_internal to
880 silc_server_send_private_message. The routine is still though
881 used only to relay private messages as server does not send
882 private messages itself.
884 Renamed silc_server_new_channel to silc_server_create_new_channel
885 and added new function sicl_server_new_channel that handles the
886 incoming New Channel packet. Added also new sending function
887 silc_server_send_new_channel to send New Channel Payload.
889 * Added new function silc_server_notify to process incoming notify
890 packet to the server/router. Server may then relay the notify
891 to clients if needed.
893 * Added new function silc_server_new_channel_user to process incoming
894 New Channel User packet. Router will redistribute the packet and
895 send JOIN notify to its local clients and locally connected servers
896 if needed. Normal server will send JOIN notify to its local client
897 on same channel when received this packet. Added also corresponding
898 sending function silc_server_send_new_channel_user to sent the
901 * Added boolean route argument to send_notif_to_channel and
902 packet_send_to_channel functions to attempt to route the packet
903 if it is TRUE and send only locally if it is FALSE.
905 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * silc_server_replace_id now broadcasts the received replace ID
908 packet if it is not broadcast packet already. The router must
909 broadcast to inform other routers about changed ID.
911 * Added backpointer to server's router into SilcServer context in
912 silcd/server_internal.h.
914 * Fixed silc_server_packet_broadcast to send correct broadcast
917 * The channel key is now distributed to the local client as soon
918 as it is received from the router (in router environment) so that
919 no other packet may be sent for the channel until client has
922 * silc_server_remove_channel_user now broadcasts the received
923 Remove Channel User packet if it is not broadcast packet already.
924 The router must broadcast to inform other routers about removed
927 * Added users field into SilcPacketContext that is a reference count
928 of the context. One can increase the reference count by calling
929 silc_packet_context_dup which is now changed to just increase the
930 reference count instead of duplicating the data. The reference
931 count is decresed by calling silc_packet_context_free that will
932 free the data after the reference count hits zero.
934 For now on the packet context and everything allocated into it
935 (including the raw packet from network) must be freed by calling
936 the new silc_packet_context_free function. Added also new function
937 silc_packet_context_alloc that must be used now to allocate the
938 context. This also means that if a routine is asynchronous from
939 silc_[client/server]_packet_parse_type the packet context must
940 be duplicated by calling silc_packet_context_dup. Otherwise it
941 gets free'd after silc_[client/server]_packet_parse_type returns.
942 Also, one must remember that if packet is duplicated then its
943 reference count must be decresed by calling the free function as
944 many times as it was duplicated.
946 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
947 from both client and server.
949 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Made joining to a channel working in router environment.
953 * Cleaned up JOIN command on server side and create function
954 silc_server_command_join_channel internal routine to make the
957 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Changed silc_command_pending list to SilcDList. Also, added
960 `ident' field to SilcServerCommandPending structure to identify
961 the reply and to call correct callback.
963 Added silc_server_command_pending_check function to replace the
964 corresnponding macro. The silc_command_pending list is not
967 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
968 to set identifier to previously allocated Command Payload. It
969 is used to set identifier for command when resending Command
972 * Added silc_command_payload_encode_payload to encode Command
973 Payload buffer from SilcCommandPayload structure.
975 * Added silc_argument_payload_encode_payload to encode Argument
976 payload buffer from SilcArgumentPayload structure.
978 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Changed WHOIS command to support router connection on server side.
981 The whois request is always sent to router unless the server is
982 standalone server. After server has received the reply from the
983 router will it send the reply to the client.
985 * Added silc_server_packet_broadcast into silcd/server.[ch] to
986 broadcast received broadcast packet. The function is used only
987 by router. The broadcast packet is always sent to the router's
990 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
991 render given ID to printable string, for log files for example.
993 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Made basic router to router connections working. At least they
996 can now connect to each other but nothing really works the way
997 they are supposed - yet.
999 * Added new initiator token to RouterConnection configuration
1000 file in silcd/serverconfig.[ch]. It is used to tell whether we
1001 are the initiator to the remote router or whether we'll expect
1002 the other end to connect.
1004 * Moved registering of listener task to silc_server_init, hence
1005 the server starts listenning as soon as it is run, even if it
1006 does not have connections to other routers. Let's see how well
1009 * Changed default connection retry timeouts for more suitable in
1012 * Removed cipher and such arguments from silc_idlist_add_client
1013 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1014 Added new function silc_idlist_add_data to add the keys and stuff
1017 * Added SilcIDListData structure and added it to SilcClientEntry
1018 and SilcServerEntry as their first field in the structure. This
1019 way we can explicitly cast the ID entries to the SilcIDListData
1020 structure and get common data for the entries. In past, we had
1021 to first check what type of connection it is and then cast it to
1022 correct ID entry type. Now, we can directly cast the opaque
1023 pointer to the SilcIDListData (no matter what ID entry it actually
1024 is) and get the data needed.
1026 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1028 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1029 in some circumstances even if threre were timeout tasks, though not
1030 IO tasks, but tasks anyway. Now fixed.
1032 * Defined SilcServerConnection structure to hold connection specific
1033 stuff about directly connected servers and routers. The definition
1034 is currently in silcd/server_internal.h. I thought about having
1035 a bit more important role fro this struct but for now it is used
1036 only when connecting to other server (or router actually).
1038 * Added connecting retry support in server when connecting to
1039 router(s). The retry feature implement exponential backoff
1040 algorithm. Also, added SilcServerParams structure to hold default
1041 parameters for server. For now, it include these retry settings
1042 and are hard coded. After server is moded to be as Silc Server
1043 Library this structure will be more important.
1045 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Changed client librarys channel->clients table to SilcList and
1048 changed code accordingly.
1050 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Changed client's channel table to SilcList and changed code
1053 accordingly. Also changed SilcChannelClientEntry to include back-
1054 pointer to the channel so that client entry can use that structure
1055 as list as well and we have fast cross-reference to the channel.
1056 This change dramatically decreased the complexity of channel
1057 handling with client entry and vice versa (removed one extra
1058 loop when searching for channel entry from many functions).
1060 * Changed server->sim from table to SilcDList and changed code
1063 * NAMES command can now be used from user interface. It will show
1064 the user list on the channel, neatly.
1066 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1067 Code now saves realname of the user if it becomes available.
1069 * Renamed configure.in to configure.in.pre and made ./prepare
1070 script to automatically add correct version string to
1071 configure.in which it creates from configure.in.pre.
1073 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * NAMES command reply now shows users mode with the nickname when
1078 * Moved silc_client_ch[u]mode[_char] functions from
1079 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1080 place sucks, they are utility functions and should be in some
1083 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1085 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1088 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1092 * Added TRQ (efficient deque and list library) into lib/trq. This is
1093 a very good list library that is currently used in the SILC. Defined
1094 SilcList API over the library because I didn't like the API very
1095 much. See lib/trq/silclist.h for the API and examples of how to
1096 use the API. Fixed various places in the code to use the new
1097 SilcList API. The SilcList is meant for lists that has a structure
1098 already defined as a list. It is not suitable to add just some
1099 context to the list (in TRQ, the context is the list actually).
1101 So, I defined SilcDList that can be used for the purpose where
1102 predefined list structure does not exit. This can be used as
1103 such list. Now some context just can be added to the SilcDList.
1104 Currently this list is not used in the SILC just yet, though there
1105 are a lot places where this can replace dynamically allocated
1106 tables and I will fix these places, later, to use SilcDList.
1107 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1108 and use TRQ internally).
1110 Also fixed some annoying warning messages that the original TRQ
1111 code generated. Also minor changes to TRQ's Makefile.in.
1113 * Added support for querying by Client ID to both WHOIS and
1114 IDENTIFY commands into server, as required by the protocol.
1116 * Removed method function pointers from SilcBuffer structure. They
1117 weren't used to anything and just increased the context size for
1118 no good reason. This change also made silc_buffer_alloc and
1119 silc_buffer_free functions inline functions.
1121 * Disabled command flooding detection support until it's fixed so
1122 that it accepts commands in but does not execute them more than once
1125 * Added silc_net_localhost(), to return local hostname, into
1126 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1127 that must be initialized before calling silc_client_init.
1129 * Added new function: silc_server_send_notify_on_channels to send
1130 notify messages to all channels client has joined. It is assured
1131 that the message is sent only once per client.
1133 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1134 lib/silcutil/silcutil.[ch] as silc_format function. The new
1135 function is generic and is used by server as well, not only by
1136 the logging routines.
1138 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1139 the provided version string was not acceptable. Added new function:
1140 silc_ske_check_version into lib/silcske/silcske.h. The function
1141 must be implemented by the application (client or server) and it
1142 does not reside in the SKE library. The function checks the version
1143 string remote end sent.
1145 * Added back pointers (to opaque context and to SilcSocketConnection)
1146 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1148 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1149 duplicate packet context structure.
1151 * Changed `notify' client operation to send same arguments as client
1152 receives from server except for ID's. ID's are mapped to correct
1153 ID entry and that is returned. Also, if channel entry is not sent
1154 by server but the notify is for channel the channel entry is sent
1155 to application (otherwise application doesn't know that it is for
1156 channel (library gets it from packet's Destination ID)).
1158 * Added silc_client_remove_from_channels into client library to
1159 remove a client from all channels it has joined to. Used when
1160 received SIGNOFF notify from server. Added also new function
1161 silc_client_replace_from_channels to replace old ID entry with
1162 new ID entry on all channels. Used when received NICK_CHANGE
1165 * Fixed ID Cache list handling in silc_idlist_get_client in
1166 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1167 to get (or query) client by ID.
1169 * Updated TODO list.
1171 * Added connection authentication status message defined by the
1172 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1173 support for these into the code in client and server side.
1175 * Added generic function silc_client_send_command to send any command
1176 with variable argument list. Application should use this function
1177 to send commands if the command functions provided by the library
1178 does not suite for the application's user interface needs.
1180 * Added new `failure' client operation. Application is notified about
1181 received failure packet if client is executing a protocol. In this
1182 case the protocol's execution has failed.
1184 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1185 is required by the protocol.
1187 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1188 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1191 * Added status flag to SilcSKE object to indicate realtime status
1192 of the SKE protocol.
1194 * Application receives now exactly same command reply arguments as
1195 the library receives from server. However, if ID is received the
1196 corresponding ID entry is returned to the application (eg. Client
1197 ID is mapped to correct SilcClientEntry entry and that is returned).
1198 Changed command_reply client operation due to this change.
1200 * Changed all ID's in commands and in command replys as ID Payloads.
1201 Change affected both client and server side codes.
1203 All ID's sent in SILC network (with execption of ID's in SILC
1204 Packet header) are sent in ID Payload to support variable length
1207 * Server now notifies nick changes and notifies all clients on
1208 the channels about the new nickname (about the new Client ID,
1211 * Implemented CMODE command to change channel modes. Supports all
1212 channel modes defined by the protocol specs except ban and invite
1213 lists. (Also, private channel key mode is supported but support for
1214 setting private channel key in client is missing, thus, this mode
1215 has no effect on client side (except that server requires that the
1216 client uses private channel key and normal channel traffic does not
1219 Also, invite mode works per se, but INVITE command does not work
1220 yet correctly, so you can set channel as invite only channel but
1221 inviting clients to the channel does not work (it is yet to be
1222 thought what's the best way to do it).
1224 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1225 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1226 Implemented CUMODE command to change user's mode on the channel.
1227 Supports all modes defined by the protocol specs.
1229 * Added NAMES command reply to return users modes on the channel.
1231 * Removed unnecessary and slow ciphers from lib/silccrypt.
1233 * Set SO_KEEPALIVE option to connection sockets by default.
1235 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1237 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1238 redefined the Notify Payload into protocol specs.
1240 * Added silc_id_payload_parse_id to get ID directly from raw
1243 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1246 accept searching by Client ID as well.
1248 * Added support for LEAVE and SIGNOFF notify types in client library.
1250 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1251 to parse ID Payload from raw data.
1253 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1255 * Added flags parameter into silc_ske_assemble_security_properties
1256 function in lib/silcske/silcske.[ch].
1258 * Changed notify client operation to fit better for notify messages
1259 sent by server. The notify payload received from server is now
1260 passed to the application (after parsing it to SilcNotifyPayload).
1261 It is application's responsibility to retrieve the arguments
1262 from the payload and show the message the way it wants. The message
1263 sent by server is implementation specific.
1265 * Changed public keys to comply with the protocol specification.
1266 Old public keys are not supported anymore and are not compatible.
1268 * Removed nickname from Channel Payload as the latest draft removed
1269 it. The client must resolve the nickname from the NAMES command
1270 reply received when it joined the channel.
1272 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1274 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1276 * Fixed some errors in protocol specification drafts.
1278 * Created lib/silccore/silcnotify.c to implement Notify Payload
1279 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1280 generic payloads described by protocol specifications. The file
1281 includes implementations for ID Payload and Argument Payload.
1283 * Changed Command Payload implementation to use the new Argument
1284 Payload. Changed command_xxxx_payload to command_payload_xxxx
1285 to comply with SILC coding conventions.
1287 * Added suppport for Argument Payload handling in Notify Payload
1288 implementation as protocol requires it. Added the new support
1289 into server and client lib as well.
1291 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1293 * Added support for multiple nicknames on same channel. [n] is
1294 added locally to the nickname if there are more than one same
1295 nicknames on the channel.
1297 * Server now sends all nicknames that matched WHOIS request.
1298 Client also shows the list received from server.
1300 * Added TOPIC command to client side. User can now set and show
1301 current topic on channel.
1303 * Added MOTD command to client and server. Also, server sends the
1304 motd when client connects to the server.
1306 * Changed version strings to comply ISO 8601.
1308 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Fixed protocol error handling in client library. It should now
1311 cope even if the SKE fails for some reason.
1313 * Made new protocol specification drafts for submitting to IETF.
1315 * Implemented TOPIC command to server in silcd/command.c.
1317 * Added two new notify types into lib/silccore/silcnotify.h:
1318 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1319 notify nickname change and topic setting/change on a channel.
1321 * API change of command_reply operation in client library. The
1322 application gets now the status type received from server as well.
1324 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1326 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1328 * Cras fixed and optimized the packet handling even further and
1329 it should work now. Minor change to the prototype of function
1330 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1332 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Added new function into lib/silcutil/silcschedule.[ch]:
1335 silc_schedule_with_fd to select() a specified fd. The function
1336 returns after timeout expires or data arrives or goes. The
1337 function is used by packet routines to wait that all data is
1338 received from network.
1340 * Fixed data reading from network in lib/silccore/silcpacket.c.
1341 The code now assures that all data is read from the fd and then
1342 continues packet processing. This was a bug fix since the code
1343 used to drop some data in some circumstances.
1345 * Added new function into lib/silcclient/client.[ch]:
1346 silc_client_start_key_exchange to start key exchange after
1347 connection has been established to server. The code internally
1348 now uses this funtion but its main purpose was to provide it
1349 for applications that perform their own connecting. After
1350 application has created a connection it merely calls this
1351 function to start the key exchange between client and server.
1352 The library takes care of everything else after that.
1354 Updated also lib/silcclient/README to explain the usage of
1357 * Do not send to application information that connection has
1358 been established. Application gets notified it by connect
1361 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Applied cras's patch to add silc_schedule_one function. The
1364 function runs scheduler once and returns.
1366 * Fixed the scheduler after cras messed it up. The timeout
1367 handling works now as it's supposed to work.
1369 * Added into lib/silccore/ silcnotify.h to include notify
1370 message types support. Changed silc_server_send_notify*
1371 functions, in server.[ch], to support those new notify types.
1372 Added the support for the notify types into client library,
1373 as well. Added new notify client operation into ops.h in
1376 * Changed silc_server_packet_send_to_channel to send normal
1377 packets instead of just channel message packets. The function
1378 is now used to send the notify packets to channels. It is not
1379 used to send channel message packets anymore, as server never
1382 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1383 va_arg()s as it seems to require it nowadays. I guess, if SILC
1384 is compiled with older va_arg() the new code should work anyway.
1386 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Splitted core library. Core library (lib/silccore) includes
1389 now only SILC protocol specific core (and common) components.
1390 Created new utility library (lib/silcutil) that includes more
1391 generic purpose stuff. The stuff for util library was taken
1392 from the old core library. This was minor and easy split.
1394 * Created SILC Client Library (lib/silcclient) that includes
1395 implementation of the SILC client without user interface. This
1396 was major move from silc/ directory. The code has been changed
1397 so that it is transparent towards the user interface. The
1398 silc/ directory includes now the same user interface as before
1399 and it uses the new client library. Read lib/silcclient/README.
1400 Basicly, the client library performs everything else related
1401 to SILC except user interface handling. Also, configuration
1402 files are considered to be part of user interface and library
1403 does not handle them.
1405 This change also changed a lot of structures, function naming etc.
1406 Most important change was that SilcClientWindow object was
1407 renamed to SilcClientConnection in the client library. Created
1408 also new file lib/silcclient/ops.h. Also added new files
1409 silc/local_command.[ch] and silc/client_ops.[ch].
1411 All these changes were made to make it easier for user interface
1412 designers to create what ever user interface for the SILC client
1415 It is also expected that the server will be moved to lib
1416 directory as well and SILC Server Library will be created;
1417 sometimes in the future.
1419 * Removed Local commands from lib/silccore/silccommand.h as
1420 they are application specific and new client library does not
1421 handle any of those anymore.
1423 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1424 old client implementation in silc/.
1426 * Added support for callback functions in SILC_LOG_* macros.
1427 Application can now set its own callbacks that will be called
1428 instead of using the default functions that will always print
1429 the debug messages to stderr (or stdout). Also, debugging can
1430 now be disabled by setting silc_debug to FALSE and re-enabled by
1431 setting it to TRUE. Note, that logging will still work even
1432 if debugging is disabled.
1434 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1435 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1436 silc_log_reset_debug_callbacks.
1438 * To enable debugging in silc client one must give now -d
1439 option on command line.
1441 * Changed silc_schedule_init to automatically allocate task queues
1442 if they are not allocated before calling it.
1444 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Added GMP 3.1 into math library.
1448 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1451 a channel in SILC network. The packet is used by servers and
1452 routers to notify other routers that user has left a channel.
1453 This little feature was missing until now. Added the feature
1454 to protocol specification as well.
1456 Added functions: silc_server_send_remove_channel_user and
1457 silc_server_remove_channel_user into server.[ch].
1459 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1460 lib/silccore/silcpacket.h. However, they are not implemented
1463 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Fixed joining to a channel and sending channel messages
1466 between server and router. The channel message sending should
1467 now work inside a cell.
1469 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Fixed the private message sending between server and router.
1472 The private message sending should now work inside a cell.
1474 * Added silc_server_replace_id into server.[ch] to replace
1475 existing ID in the SILC network.
1477 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1478 and silc_idlist_replace_server_id into idlist.[ch] in server.
1480 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Fixed the server to server connections. Server can again now
1483 connect to router. Router to router connections probably does
1486 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Added dynamic protocol registering support. Now protocols can
1489 registered and unregistered on the fly. Patch by cras.
1491 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1493 * Added lib/contrib directory to hold routines that some platforms
1494 don't have but are needed by SILC.
1496 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1497 into lin/contrib to provide getopt() and getopt_long() for
1498 those who don't have it.
1500 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Added AWAY command to client. When away message is set and
1503 client receives a private message packet the client automatically
1504 replies to the sender with the away message.
1506 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1507 bug seemed to be the cause of recent problems when compiling
1510 * Added version detection support to SKE protocol specification
1511 and added the new changes to the SKE implementation as well.
1512 There were other minor changes in the SKE protocol as well.
1514 Many changes in lib/silcske/silcske.[ch] and in
1515 lib/silcske/payload.[ch].
1517 * Added ^U functionality, clear input line. Patch from cras.
1519 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Mainly small bugfixes on core library. Fixed some debugging
1522 logging and buffer overflow in silclog.c.
1524 * Updated config.sub and config.guess on the distribution tree.
1526 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Added command lagging support in server. Client may execute
1529 commands now only once in two seconds.
1531 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Optimized packet reception. MAC computation and checking is now
1534 also more optimized. A lot previously duplicated code is now
1535 used as generic by both client and server.
1537 * Fixed key pair generation in clientutil.c
1539 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1541 * Added into lib/silccore/silcbufutil.[ch] new function;
1542 silc_buffer_realloc.
1544 * Moved generic packet sending/encryption functions to
1545 lib/silccore/silcpacket.[ch] from client and server. Some
1546 rewriting of the functions.
1548 * Moved all generic packet reception/decryption functions to
1549 lib/silccore/silcpacket.[ch] from client and server. The
1550 packet processing is now much cleaner in both client and server.
1551 These were major changes in both client and server.
1553 * Created many common functions in server to do packet sending.
1554 Previously code were duplicated a lot, this has been removed
1557 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1559 * Rewrote major parts of the ID cache system. Don't know
1560 whether it is better now or not but at least the API is more
1563 * Major rewrite on ID cache stuff on client because of the ID
1564 cache API changes. Added idlist.c to client.
1566 * Also major rewrite on ID cache stuff on server as well.
1567 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1568 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1569 in hand, instead they are all put into the ID cache system now.
1570 All server_idlist_* routines uses ID cache now instead of
1571 traversing its own lists (those lists does not exist anymore).
1572 SilcIDList though still exists. Also, SilcXXXEntry's are
1575 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1577 * Finally made the SKE implementation compliant to the protocol
1578 specification. All mp integers are now binary encoded as
1579 opposed being HEX encoded.
1581 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1584 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1585 functions: silc_[encode/decode]_pem. Also added function
1586 silc_encode_pem_file to PEM encode with newlines ('\n') for
1589 * SILC public keys are now encoded either PEM or binary. Same
1590 option is for private keys as well. By default private keys
1591 are binary encoded and public keys PEM encoded. Silly HEX
1592 encoding were removed.
1594 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1595 function to create fingerprints.
1597 * Fixed a bug in SHA1; does not change the original data anymore.
1599 * Partly implemented INFO command on client and server side.
1600 Fixed CLEAR command. Changes to SERVER command; show current
1601 server(s) when giving command without arguments. Added
1602 VERSION command to client.
1604 * Added check to server that unregistered connections cannot
1605 execute commands (unless it is specificly allowed).
1607 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Fixed screen refresh.
1611 * Fixed channel joining bug from client. On some circumstances
1612 client tried to join to a channel it had already joined.
1614 * Added public key verification process into client's protocol.c.
1615 The client now verifies the public key from user and saves
1616 it into ~./silc/serverkeys/ directory.
1618 Added into: clientutil.[ch]: silc_client_verify_server_key.
1620 * Changed SKE protocol's silc_ske_initiator_finish function
1621 to accept callback function that verifies the received public
1622 key. Removed old silc_ske_verify_public_key function.
1624 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1626 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1627 silc_pkcs_private_key[_data]_set.
1629 * Made the password and public authentication more cleaner in
1630 server's protocol.c.
1632 * Removed historic and obsolete protocol `channel_auth' from
1633 both client and server.
1635 * Removed wrong way of sending command status messages from
1636 server to client in server's command.c. The old way violated
1637 protocol specification.
1639 Changes to silccore/silccommand.[ch]: removed
1640 silc_command_encode_status_payload -> not needed anymore,
1641 changed silc_command_encode_payload_va to accept extra
1642 argument on variable argument list. The argument type must
1643 now be provided to the function. Also, added new function:
1644 silc_command_encode_reply_payload_va which is same as
1645 normal command_encode_payload_va except command status type
1646 is provided as extra argument.
1648 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1650 * Added ~./silc directory handling. The directory includes the
1651 public and private keys for the client.
1653 Added silc_client_check_silc_dir, silc_client_create_identifier
1654 and silc_client_load_keys.
1656 * Implemented SILC protocol compliant public key. Added public
1657 and private key saving to and loading from files.
1659 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1660 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1661 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1662 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1663 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1665 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1666 silc_pkcs_load_[public/private]_key.
1668 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Added silc_server_get_route (route.[ch]) to get connection
1671 data for the fastest route for given ID.
1673 * Implemented INVITE command on client and server. The command
1674 were re-defined in the SILC Protocol Specification and the
1675 implementation now complies with the specification.
1677 * Implemented PING command on client and server.
1679 * Implemented NAMES command on client and server. The server side
1680 supports currently only normal server not router server yet.
1681 Some changes to NAMES definition in SILC protocol specification.

1685 * Implemented LEAVE command on client and server.
1687 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use

1689 should not violate the protocol specification anymore.
