1 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added support for quit message that client can "leave" on the
4 channel when it quits the SILC. It is ditributed inside the
5 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7 Added silc_server_free_client_data that will take the
8 signoff message as argument.
10 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Updated parts of the protocol specification to keep it up
15 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
17 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
18 payloads in one packet.
20 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
21 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
22 use now the new List flag.
24 * Also deprecated the following packet types: REPLACE_ID,
25 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
27 * Added list support for Notify packet in server.
29 * Added silc_server_send_notify_channel_change to send the
30 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
31 the silc_server_send_replace_id.
33 * Added silc_server_send_notify_nick_change to send the
34 NICK_CHANGE notify type. Deprecates the function
35 silc_server_send_replace_id.
37 * Added silc_server_send_notify_join to send the JOIN notify type.
38 Deprecates the function silc_server_send_new_channel_user.
40 * Added silc_server_send_notify_leave to send LEAVE notify type.
41 Deprecates the function silc_server_send_remove_channel_user.
43 * Added silc_server_send_notify_cmode and
44 silc_server_send_notify_cumode to send CMODE and CUMODE notify
45 types. Deprecates the silc_server_send_set_mode function.
47 * Added SERVER_SIGNOFF notify type to indicate that server has
48 quit. This means that all clients on the channel from that
49 server will drop. This can be also used when netsplit happens.
51 Deprecated REMOVE_ID packet type since it is not needed anymore
54 Added silc_server_send_notify_server_signoff to send the
55 SERVER_SIGNOFF notify type. Deprecates the function
56 silc_server_send_remove_id.
58 Added also silc_server_send_notify_signoff to send the
61 * Employed the PKCS #1. It is the mandatory way to do RSA in the
62 SILC protocol from this day on. Changed the protocol
63 specification as well.
65 * Added silc_server_send_notify_topic_set to send TOPIC_SET
66 notify type. It is used between routers to notify about
67 topic changes on a channel.
69 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
72 * Partly updated the protocol specification to comply with the
73 changes now made. It is still though a bit outdated.
75 * The JOIN notify type now takes one extra argument <Channel ID>.
76 The packet used to be destined to the channel but now the
77 JOIN type may be sent as list thus it is impossible to
78 destine it to any specific channel. By adding this argument
81 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Added CREDITS file. The CHANGES and CREDITS file will appear
84 in the distribution as well.
86 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
88 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
89 types in the server's silcd/packet_receive.c.
91 * Implemented CMODE and CUMODE to work in router environment.
93 * Fixed minor encoding and decoding buglet from the
94 lib/silccore/silcmode.c.
96 * Fixed buffer overflow from lib/silcclient/command.c in USERS
99 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
101 * Changed all SilcConfigServer* and silc_config_server* to
102 SilcServerConfig* and silc_server_config*, respectively.
105 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
107 * Associated the ID (client or server ID) to the Authentication
108 Payload to avoid any possibility of forging. Updated the
109 protocol specification and the code accordingly.
111 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * The RSA key length is now save to the RsaKey context in the
114 key generation process in lib/silccrypt/rsa.c. The key length
115 is now used to figure out the maximum size of the block allowed
116 to be encrypted/signed.
118 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
119 is equivalent to the silc_mp_mp2bin but does not allocate any
122 * Changed silc_mp_mp2bin API to take length argument. If it is
123 non-zero then the buffer is allocated that large. If zero, then
124 the size is approximated using silc_mp_sizeinbase, which however
127 * Created Global RNG API which is global RNG that application can
128 initialize. After initializing, any routine anywhere in the
129 code (including library) can use RNG without allocating a new
130 RNG object. This was done to allow this sort of use of the
131 RNG in code that has no chance to allocate RNG object. All
132 applications currently allocate this and many routines in the
133 library use this. Affected file lib/silccrypt/silcrng.[ch].
135 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
136 it to use the Global RNG API.
138 * Defined Authentication Payload into protocol specification that
139 is used during SILC session to authenticate entities. It is
140 used for example by client to authenticate itself to the server
141 to obtain server operator privileges.
143 Implemented this payload into the lib/silccore/silcauth.[ch].
144 Implemented also routines for public key based authentication
145 as the new protocol specification dictates.
147 Moved definitions of different authentication methods from
148 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
150 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
151 silc_pkcs_verify and silc_pkcs_sign_with_hash and
152 silc_pkcs_verify_with_hash functions into the file
153 lib/silccrypt/silcpkcs.[ch].
155 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * The client entry's userinfo pointer must be always valid.
158 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
159 will fail since it requires the userinfo. Now, the userinfo
160 is allocated as "" if actual userinfo does not exist. Actually,
161 it must exist and it is totally Ok to drop client connections
162 that does not announce the userinfo. However, we will make
163 this workaround for now.
165 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
166 to return the remote port by socket.
168 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
170 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
171 SILC_SERVER_PENDING_EXEC and added an new macro
172 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
173 data or when error occurs while processing the pending command.
175 Added new argument `destructor' into silc_server_command_pending
176 and to the SilcServerCommandPending object. This destructor is
177 now called after calling the pending callback or if error occurs
178 immediately. If error occurs the actual pending callback won't
179 be called at all - only the destructor. The destructor may be
180 NULL if destructor is not needed.
182 All this applies for client library code as well. Similar
183 changes were made there as well for the pending commands.
185 In the client, the application must now allocate the
186 SilcClientCommandContext with the silc_client_command_alloc
189 * Added reference counter to the SilcServerCommandContext. Added
190 function silc_server_command_alloc and silc_server_command_dup
193 Same type of functions added to the client library for the same
196 * Removed the cmd_ident from IDListData away since it is now
197 global for all connections. It is the command identifier used
198 in command sending and with pending commands. The affected file
201 * Added reference counter to the SilcSocketConnection objecet to
202 indicate the usage count of the object. The object won't be
203 freed untill the reference counter hits zero. Currently only
204 server uses this, and client ignores it. The client must be
205 set to use this too later. The affected files are
206 lib/silccore/silcsockconn.[ch]. Added also the function
207 silc_socket_dup to increase the reference counter.
209 This was mainly added because it is possible that the socket
210 is removed underneath of pending command or other async
211 operation. Now it won't be free'd and proper DISCONNECTING
212 flags, etc. can be set to avoid sending data to connection that
213 is not valid anymore.
215 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
216 the connection. After that it sets SILC_SET_DISCONNECTED.
217 It is, however, possible that the socket data is not still freed.
218 The silc_server_packet_process now checks that data is not
219 read or written to connection that is DISCONNECTED. The socket
220 get's freed when the reference counter hits zero.
222 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
224 * Changed the client operation API: channel_message operation's
225 `sender' is now the client entry of the sender, not the nickname
226 and the `channel' is the channel entry, not the channel name.
228 In the private_message operation the `sender' is now also the
229 client entry of the sender not the nickname.
231 Affected file is lib/silcclient/ops.h and all applications
232 using the client operations.
234 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Moved the calling of ops->connect() from connect_to_server_final
237 into receive_new_id functin since that is the point when the
238 client is actually allowed to send traffic to network. The
239 affected file is lib/silcclient/client.c.
241 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
244 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
245 (if needs broadcasting) instead of broadcasting the packets one
246 by one which would make a burst in the network traffic.
248 * Added `broadcast' argument to the functions in silcd/server.[ch]
249 silc_server_create_new_channel[_with_id] to indicate whether
250 to send New Channel packet to primary router.
252 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
254 * Added new function into the silcd/server.[ch] files:
255 silc_server_create_new_channel_with_id to create new channel with
256 already existing Channel ID.
258 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
259 lib/silccore/silcpacket.h. This packet is used t send list of
260 Set Mode payloads inside one packet. Server uses this to set
261 the modes for the channels and clients on those channels, that it
262 announced to the router when it connected to it. The protocol
263 specification has been updated accordingly.
265 * The silc_server_new_channel did not handle the packet coming
266 from normal server as it normally does not send that. However,
267 when it announces its channels it does send it. Implemented
268 the support for that.
270 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
271 into the file lib/silccore/id.h.
273 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
275 * Fixed memory leaks in the functions silc_idlist_del_client,
276 silc_idlist_del_channel and silc_idlist_del_server in the file
277 silcd/idlist.c. All of those leaked like a sieve.
279 * Fixed some small memory leaks in the client's function
280 silc_client_notify_by_server.
282 * Added functions into silcd/server.c: silc_server_announce_clients,
283 silc_server_announce_channels and silc_server_announce_server.
284 These functions are used by normal and router server to announce
285 to its primary router about clients, channels and servers (when
286 router) that we own. This is done after we've connected to the
289 These functions effectively implements the following packet types:
290 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
291 and SILC_PACKET_NEW_ID_LIST.
293 * Added new functions into the silcd/packet_receive.[ch]:
294 silc_server_new_id_list, silc_server_new_channel_list and
295 silc_server_new_channel_user_list to handle the incoming
296 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
298 * Added support of changing Channel ID in the function
299 silc_server_replace_id. If the server that announces a channel
300 to the router already exists in the router (with same name but
301 with different Channel ID), router is responsible to send
302 Replace ID packet to the server and force the server to change
303 the Channel ID to the one router has.
305 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
306 client that the Channel ID has been changed by the router. The
307 normal server sends this to the client. Client must start using
308 the new Channel ID as the channel's ID.
310 Implemented handling of this new type into lib/silcclient/client.c
311 into the function silc_client_notify_by_server.
313 * Added new function silc_idlist_replace_channel_id into the files
314 silcd/idlist.[ch] to replace the Channel ID.
316 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Call silc_server_command_identify_check always when processing
319 the IDENTIFY command in silcd/command.c
321 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
324 send keepalive packets. The packet can be sent by clients,
327 Added function silc_socket_set_heartbeat into the file
328 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
329 If not set, the heartbeat is not performed. The actual
330 heartbeat is implemented in the low level socket connection
331 library. However, application is responsible of actually
334 Added silc_server_send_heartbeat to send the actual heartbeat
335 packet into silcd/packet_send.[ch]. Server now performs
336 keepalive with all connections.
338 * Added silc_task_get_first function into lib/silcutil/silctask.c
339 to return the timeout task with shortest timeout. There was a bug
340 in task unregistration that caused problems. TODO has been
341 updated to include that task system must be rewritten.
343 * The client library will now resolve the client information when
344 receiving JOIN notify from server for client that we know but
345 have incomplete information.
347 * Rewrote parts of silc_server_remove_from_channels and
348 silc_server_remove_from_one_channel as they did not remove the
349 channel in some circumstances even though they should've.
351 * Encryption problem encountered in server:
353 The LEAVE command used to send the Channel Key packet to the
354 router immediately after generating it. However, the code
355 had earlier sent Remove Channel user packet but not immediately,
356 ie. it was put to queue. The order of packets in the router
357 was that Channel Key packet was first and Remove Channel User
358 packet was second, even though they were encrypted in the
359 reverse order. For this reason, MAC check failed. Now, this
360 is fixed by not sending the Channel Key packet immediately but
361 putting it to queue. However, this is more fundamental problem:
362 packets that are in queue should actually not be encrypted
363 because packets that are sent immediately gets encrypted
364 actually with wrong IV (and thus MAC check fails). So, packets
365 that are in queue should be encrypted when they are sent to
366 the wire and not when they put to the queue.
368 However, the problem is that the current system has not been
369 designed to work that way. Instead, the packet is encrypted
370 as soon as possible and left to the queue. The queue is then
371 just purged into wire. There won't be any fixes for this
372 any time soon. So, the current semantic for packet sending
375 o If you send packet to remote host and do not force the send
376 (the packet will be in queue) then all subsequent packets to the
377 same remote host must also be put to the queue. Only after the
378 queue has been purged is it safe again to force the packet
381 o If you send all packets immediately then it safe to send
382 any of subsequent packets through the queue, however, after
383 the first packet is put to queue then any subsequent packets
384 must also be put to the queue.
386 Follow these rules and everything works fine.
388 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
390 * Added new function silc_server_remove_clients_by_server to
391 remove all client entries from ID list when the server connection
392 is lost. In this case it is also important to invalidate all
393 client entires as they hold the invalid server entry. This
394 fixes fatal bug when server has lost connection and will reconnect
397 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
399 * Made some sanity checks to silc_server_daemonise like to check
400 whether the requested user and group actually exists.
402 * Added sanity check to SKE's silc_ske_responder_finish to check
403 that the public and private key actually is valid.
405 * Invalidate the client's nickname when receiving Replace ID
406 packet and the Client ID is being replaced. This means that the
407 server will query the nickname if someone needs it (client)
410 * Sort the ID Cache in client library when the ID Cache data
411 has changed (needs sorting).
413 * Do not allow for SILC client to create several connections to
414 several servers. The client does not support windows right now
415 and generating multiple connections causes weird behaviour.
417 Irssi-silc client does support windows and can handle several
418 connections without problems, see: www.irssi.org and SILC plugin.
420 * Fixed some places where client was added to the IDList. The
421 rule of thumb is following (in order to get everything right):
422 If the client is directly connected local client then the
423 `connection' argument must be set and `router' argument must be
424 NULL to silc_idlist_add_client function. If the client is not
425 directly connected client then the `router' argument must
426 bet set and the `connection' argument must be NULL to the
427 silc_idlist_add_client function.
429 * The funtion silc_server_packet_send_local_channel actually did
430 not check whether the client was locally connected or not. It
431 does that now. Fixed a bug related to LEAVE command.
433 * Fixed Remove Channel User payload parsing bug in server's
434 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
436 * The server's silc_server_save_channel_key now checks also the
437 global ID list for the channel as it might not be in the local
438 list. Fixed a bug related to LEAVE command.
440 * Is this the end of the [<unknown>] buglet that has been lurking
441 around for a long time? A little for loop fix in server's
442 silc_server_command_whois_parse that is used by both IDENTIFY
443 and WHOIS command. At least, this was a clear bug and a cause
444 of one type of [<unknown>] buglet.
446 * WHOIS and IDENTIFY commands call the function
447 silc_server_command_[whois/identify]_check function even if
448 we are not router server.
450 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Added --with-gmp configuration option. If set the GMP
453 is always compiled in the SILC source tree. If not set then
454 it is checked whether the system has the GMP3 installed. If
455 it has then the GMP won't be compiled (the system's headers
456 and library is used), if it doesn't have it then the GMP is
457 compiled in the SILC source tree.
459 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * Changed RSA private exponent generation to what PKCS #1
462 suggests. We try to find the smallest possible d by doing
463 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
464 not security fix but optimization.
466 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Added new config entry [Identity] to fork the server and run
469 it as specific user and group. A patch from Bostik.
471 * Imported Dotconf configuration library into lib/dotconf.
472 This will be used to create the SILC configuration files later.
473 It will appear in the distsribution after this commit.
475 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
477 * A big code auditing weekend happening. Auditing code for
478 obvious mistakes, bugs and errors. Also, removing any code
481 Removed files for being obsolete:
483 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
484 inline in the file lib/silcutil/silcbuffer.h)
486 o lib/silcutil/silcbufutil.c (the header has inline versions)
488 Changed code to fix possible error conditions:
490 o The buffer formatting routines now check that the destination
491 buffer really has enough space to add the data. This applies for
492 both buffer formatting and unformatting
493 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
494 unformatting was changed to accomodate following rules:
495 XXX_*STRING_ALLOC will allocate space for the data into the pointer
496 sent to the function while XXX_*STRING will not allocate or copy
497 the data into the buffer. Instead it sets the pointer from the
498 buffer into the pointer sent as argument (XXX_*STRING used to
499 require that the pointer must be allocated already). This change
500 makes this whole thing a bit more consistent and more optimized
501 (note that the data returned in the unformatting with XXX_*STRING
502 must not be freed now). The routines return now -1 on error.
504 o Tried to find all code that use buffer_format and buffer_unformat
505 and added return value checking to prevent formatting and
506 especially unformatting errors and possible subsequent fatal
509 o Changed ske->x and ske->KEY to mallocated pointers in
510 lib/silcske/silcske.h. Fixed possible data and memory leak.
512 o Added return value checking to all *_parse* functions. Fixed
513 many memory leaks as well.
515 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
516 so that buffer overflows would not happen. All code now also
517 checks the return value as it can fail.
519 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Added reconnection support to server if the normal server looses
522 its connection to the router (for example if router is rebooted).
523 The server performs normal reconnection strategy implemented
524 to the server. Affected file silcd/server.c.
526 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * Added new packet type SILC_PACKET_SET_MODE that is used to
529 distribute the information about changed modes (for clients,
530 channels and clients channel modes) to all routers in the
531 network. Updated the protocol specification accordingly.
533 Added functions into silcd/packet_send.c and
534 silcd/packet_receive.c: silc_server_send_set_mode,
535 silc_server_set_mode.
537 Added new files silcmode.[ch] into lib/silccore that implements
538 the encoding and decoding of Set Mode Payload. Added new type
539 SilcSetModePayload. Moved the definitions of different modes
540 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
542 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Oops, a little mistake in server's connection authentication
545 protocol. The protocol is not ended with FAILURE but with
546 SUCCESS if the authentication is Ok. :) Affected file is
549 * Implemented NICK_CHANGE notify handling in server in the file
550 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
551 the local clients on the channel. After the changing nickname
552 in router environment snhould work and the [<unknown>] nickname
553 should appear no more.
555 The silc_server_replace_id function that receives the Replace ID
556 payload now sends the NICK_CHANGE notify type also in the file
557 silcd/packet_receive.c
559 * Changed WHOIS and IDENTIFY command to support the maximum amount
560 of arguments defined in protocol specs (3328 arguments). This
561 fixed a bug that caused problems when there were more than three
564 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * Added extra parameter, command identifier, to the
567 silc_client_send_command so that explicit command identifier
570 Changed that ID list routines uses specific command identifier
571 when sending WHOIS/IDENTIFY requests to the server so that they
572 can be identified when the reply comes back.
574 Affected files lib/silcclient/command.[ch],
575 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
577 * Added `sender' argument to silc_server_packet_send_to_channel
578 to indicaet the sender who originally sent the packet to us
579 that we are now re-sending. Ignored if NULL. Affected file
580 silcd/packet_send.[ch].
582 * Added some server statistics support in silcd/server_internal.h
583 SilcServerStatistics structure and around the server code. Also
584 send some nice statistics information when client is connecting
587 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
589 * Fixed channel ID decoding in server's JOIN command reply in
590 silcd/command_reply.c
592 * Fixed braodcasting of replace ID payload to not to send it if
593 we are standalone server in silcd/packet_receive.c.
595 * Fixed all channel message sending routines to not to send
596 packets to clients that has router set, since they are routed
597 separately in the same function earlier. Affects file
598 silcd/packet_send.c and all channel packet sending functions.
600 * In USERS reply, res_argv[i] are not allocated, the table
601 is allocated. Thus changed that free the table, not its
604 * In server's whois_check and identify_check if the client is
605 locally connected do not send any WHOIS commands - they are not
608 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Fixed some minor bugs in client when sending WHOIS command. The
611 arguments was in wrong order.
613 * Removed statis function add_to_channel from server in
614 silcd/command.c that was previously used with the joining but
617 * Tested USERS command in router environment successfully with two
618 routers, two servers and two clients.
620 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
622 * Reorganized the USERS command and command reply in client library
623 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
624 When the command is given by user we register a pending command
625 callback that will reprocess the command after the reply has been
626 received from the server. When reprocessing the packet we then
627 display the information. Thus, the USERS information is displayed
628 now in the command callback instead of in the command reply
629 callback. The processing of the command is same as previously
630 when server has sent the command reply in the JOINing process.
632 * Added to USERS command in silcd/command_reply.c to join the client,
633 we didn't use to know about, to the channel after we've created
634 a client entry for it. Also, for clienet we did know already still
635 check whether it is on the channel or not and add it if not.
637 * Removed silc_server_command_join_notify as the function and its
640 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Changed the client's pending command handling to the same as the
643 server's pending command handling. It is also now possible to
644 execute command reply functions from other command reply
645 function as the function callbacks for commands and command
646 replies are one and same. The pending commands are not static
647 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
648 in client connection context. Thus, pending commands are server
649 connection specific as it is convenient.
651 Changed the function silc_client_command_pending and
652 silc_client_command_pending_del and added new function
653 silc_client_command_pending_check. Removed the
654 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
657 * Added cmd_ident, current command identifier, to the client
658 connection context in lib/silcclient/client.h to keep track on
659 command identifiers used in command sending. Client's command reply
660 function handling now supports the mandatory command identifiers.
662 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
663 funtions in client to fully support pending command callbacks.
665 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
666 as one of the arguments to the application in the command reply
669 * NOTE: The FORWARDED flag is depracated. It used to be depracated
670 before first releasing SILC but came back. Now it is removed again
671 and should come back nomore. The FORWARDED flag was used only
672 by the JOINing procedure by forwarding the command packet to router.
673 Now, the JOINing procedure has been changed to more generic (due
674 to various router environment issues) and FORWARDED is not needed
675 anymore for anything. The protocol specification is yet to be
678 Now, removed silc_server_packet_forward from server and the flag
679 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
681 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Renamed NAMES command to USERS command. The NAMES was named that
684 due to historical reasons. Now it is renamed. Also, rewrote
685 parts of the USERS command. The nickname list is not sent anymore
686 by the server. Only Client ID and mode lists are sent in the USERS
687 command. Changed this also to the protocol specification.
689 The client now resolves the names and stuff after it receives
690 the USERS list from the server when joining to the channel.
692 * WHOIS and IDENTIFY commands has been changed to support multiple
693 Client ID's per command. One can now search for multiple users
694 in the network by sending only one WHOIS or IDENTIFY command.
695 Changed the code and the protocol specifications.
697 * Removed silc_server_command_identify_parse and changed that IDENTIFY
698 uses silc_server_command_whois_parse to parse the request. */
700 * If normal server, do not parse the WHOIS and IDENTIFY requests
701 before sending it to the router. Saves some time.
703 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
705 * Fixed JOIN command on client library. Wrong number of arguments
706 used to crash the client.
708 * Added silc_server_channel_has_global function to check whether
709 channel has global users or not.
711 * Added silc_server_channel_has_local function to check whether channel
712 has locally connected clients on the channel.
714 * The silc_server_remove_from_one_channel now checks whether the
715 channel has global users or not after given client was removed from
716 the channel. It also checks whether the channel has local clients
717 on the channel anymore. If it does not have then the channel entry
718 is removed as it is not needed anymore.
720 * The silc_server_notify now checks on JOIN notify whether the joining
721 client is one of locally connected or global. If it is global then
722 the channel has now global users on the channel and that is marked
723 to the channel entry. Also, it now saves the global client to
724 global list who is joining and JOINs it to the channel. This is
725 for normal server, that is.
727 Changed silc_server_send_notify_on_channel,
728 silc_server_packet_relay_to_channel and
729 silc_server_packet_send_to_channel check if we are normal server
730 and client has router set (ie. global client) do not send the
731 message to that client, as it is already routed to our router.
733 * Implemented LEAVE notify type handling in silc_server_notify
736 * Tested LEAVE command in router environment successfully. Tested
737 with two routers, two servers and two clients.
741 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
743 * Implemented SIGNOFF notify type handling in silc_server_notify
746 * silc_server_remove_id now removes the client entry from all channels
747 it has joined and thusly sends SIGNOFF notify type.
749 * Rewrote the NAMES list generation in server by removing two excess
750 loops. The lists are created now inside one loop.
752 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * silc_server_remove_channel_user checks now also global list
755 for channel and client.
757 * silc_server_new_channel_user checks now both local and global
758 list for channel and client. Fixed a bug in client id decoding.
759 Used to decode wrong buffer.
761 * silc_server_channel_message checks now both local and global
762 list for channel entry.
764 * Tested channel joining (hence JOIN) in router environment
765 successfully. Tested with two routers, two servers and two
768 * Tested channel message sending in router environment successfully.
770 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Added silc_server_save_channel_key into server.[ch] to save the
773 received channel key in Channel Key payload processing. It is
774 also used in JOIN command reply handling.
776 Equivalent function silc_client_save_channel_key added into
777 client.[ch] into client library.
779 * Changed JOIN command reply to send information whether the channel
780 was created or not (is existing already) and the channel key
781 payload. Changed protocol specs accordingly.
783 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
784 the request was sent by ID and not by nickname. Crashed on
787 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
790 now correctly save the received data.
792 * silc_server_free_sock_user_data now notifies routers in the
793 network about entities leaving the network.
795 At the same time implemented functions silc_server_remove_id
796 and silc_server_send_remove_id to receive and send REMOVE_ID
797 packets. The packet is used to notify routers in the network
798 about leaving entities. The ID removed will become invalid in
801 * Added function silc_idlist_del_server into server. Removes and
802 free's server entry from ID list.
804 * silc_server_private_message function now checks, if we are router,
805 that the destination ID really is valid ID, naturally.
807 * In router when NEW_ID packet is received (for new client) the
808 hash of the Client ID is saved in the ID Cache but the
809 client->nickname is set to NULL, instead of putting the hash
812 IDENTIFY command now also checks that client->nickname must be
813 valid. If it is not if will request the data from the server who
814 owns the client. Added new function
815 silc_server_command_identify_check.
817 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
818 to set the command to already allocated Command Payload.
820 * Tested private message sending in router environment with two
821 routers, two servers and two clients. Fixed minor bugs and now
824 * Fixed segfault from client's NAMES command. Used to crash if
827 * Forwarded packets must not be routed even if it is not destined
828 to the receiver. Changed server code comply with this.
830 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Added `require_reverse_mapping' boolean value to ServerParams
833 structure. If TRUE (not default) the server will require that
834 the connecting host has fully qualified domain name.
836 If the reverse mapping is not required and hostname could not be
837 found the IP address is used as hostname.
839 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
841 * Implemented version string checking to both client and server.
842 The check is incomplete currently due to the abnormal version
843 strings used in development version of SILC.
845 * Changed all command functions in server to use the new
848 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
850 * Changed char *data to unsigned char *data in ID Cache system to
851 support binary data as ID Cache data. Changed code to support
852 binary data in lib/silccore/idcache.c.
854 * Renamed silc_server_packet_relay_command_reply to
855 silc_server_command_reply as it is normal packet receiving
856 function. Rewrote the function to accept command replys for
857 servers and not only for clients.
859 * Mark remote router always as registered server if we are connecting
860 to it. Otherwise, commands sent by the router to us are ignored.
862 * All ID List find routines now returns the ID Cache Entry pointer
863 as well if requested.
865 * WHOIS command works now in router environment, tested with two
866 routers, two servers and two clients.
868 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
869 in router environment (as it is almost equivalent to WHOIS) but
870 hasn't been tested thoroughly. Added new functions:
872 silc_server_command_identify_parse
873 silc_server_command_identify_send_reply
874 silc_server_command_identify_from_client
875 silc_server_command_identify_from_server
877 * Disabled route cache adding because adding two different ID's with
878 same IP replaces the old cache entry thus giving wrong route.
879 The entry->router->connection is always the fastest route anyway
880 so route cache may not be needed. Of course, new routes maybe
881 established after receiving the ID when the entry->router->connection
882 might not be anymore the most optimal.
884 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Add route cache for received ID for fast routing.
888 * Added silc_server_packet_route to route received packet on router
889 that is not destined to us.
891 * Renamed silc_server_get_route to silc_server_route_get.
893 * Added id_string and id_string_len fields into SilcServer to
894 include encoded ServerID for fast comparing without excess
895 encoding of the ID's.
897 * Cleaned up WHOIS command on server side. Added following static
900 silc_server_command_whois_parse
901 silc_server_command_whois_check
902 silc_server_command_whois_send_reply
903 silc_server_command_whois_from_client
904 silc_server_command_whois_from_server
906 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
907 arguments in command replies. All command functions should be
908 updated to use this macro.
910 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Minor typo fixes on command reply handling on server.
914 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Added silc_server_command_add_to_channel internal routine to add
917 the client to the channel after router has created the channel and
918 sent command reply to the server.
920 * Added generic silc_server_send_command to send any command from
923 * Use static buffer with ID rendering instead of duplicating data.
925 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Fixed a channel user mode bug when joining to a channel server gave
928 everybody channel founder rights, oops.
930 * We mark ourselves as the router of the incoming server connection
931 if we are router ourselves. This way we can check in some packet
932 sending functions whether it is locally connected server. For
933 incoming router connections we put NULL.
935 * For router sending packets locally means now always sending the
936 packet cell wide; to local clients and local servers. For normal
937 server sending packet locally means sending it to only local
940 * Fixed the JOIN command to really work in router environment. If the
941 channel is created it is always created by the router. Router is
942 also responsible of making the initial joining to the channel,
943 sending JOIN notify to the sending server and distributing
944 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
945 does not exist server doesn't do anything else but forward the
946 command to the router which performs everything.
948 * Added silc_server_send_channel_key function to send the Channel Key
951 * Added silc_server_create_channel_key to create new channel key. The
952 channel key is now re-generated everytime someone joins or leaves
953 a channel, as protocol dictates. Note: channel->key_len is the
956 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Splitted server.[ch] finally. Created now packet_send.[ch] and
959 packet_receive.[ch] to separate packet sending and receiving
960 routines. The server.[ch] now includes everything else including
961 actual packet processing (writing and reading data) and other
964 Renamed silc_server_private_message_send_internal to
965 silc_server_send_private_message. The routine is still though
966 used only to relay private messages as server does not send
967 private messages itself.
969 Renamed silc_server_new_channel to silc_server_create_new_channel
970 and added new function sicl_server_new_channel that handles the
971 incoming New Channel packet. Added also new sending function
972 silc_server_send_new_channel to send New Channel Payload.
974 * Added new function silc_server_notify to process incoming notify
975 packet to the server/router. Server may then relay the notify
976 to clients if needed.
978 * Added new function silc_server_new_channel_user to process incoming
979 New Channel User packet. Router will redistribute the packet and
980 send JOIN notify to its local clients and locally connected servers
981 if needed. Normal server will send JOIN notify to its local client
982 on same channel when received this packet. Added also corresponding
983 sending function silc_server_send_new_channel_user to sent the
986 * Added boolean route argument to send_notif_to_channel and
987 packet_send_to_channel functions to attempt to route the packet
988 if it is TRUE and send only locally if it is FALSE.
990 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * silc_server_replace_id now broadcasts the received replace ID
993 packet if it is not broadcast packet already. The router must
994 broadcast to inform other routers about changed ID.
996 * Added backpointer to server's router into SilcServer context in
997 silcd/server_internal.h.
999 * Fixed silc_server_packet_broadcast to send correct broadcast
1002 * The channel key is now distributed to the local client as soon
1003 as it is received from the router (in router environment) so that
1004 no other packet may be sent for the channel until client has
1007 * silc_server_remove_channel_user now broadcasts the received
1008 Remove Channel User packet if it is not broadcast packet already.
1009 The router must broadcast to inform other routers about removed
1012 * Added users field into SilcPacketContext that is a reference count
1013 of the context. One can increase the reference count by calling
1014 silc_packet_context_dup which is now changed to just increase the
1015 reference count instead of duplicating the data. The reference
1016 count is decresed by calling silc_packet_context_free that will
1017 free the data after the reference count hits zero.
1019 For now on the packet context and everything allocated into it
1020 (including the raw packet from network) must be freed by calling
1021 the new silc_packet_context_free function. Added also new function
1022 silc_packet_context_alloc that must be used now to allocate the
1023 context. This also means that if a routine is asynchronous from
1024 silc_[client/server]_packet_parse_type the packet context must
1025 be duplicated by calling silc_packet_context_dup. Otherwise it
1026 gets free'd after silc_[client/server]_packet_parse_type returns.
1027 Also, one must remember that if packet is duplicated then its
1028 reference count must be decresed by calling the free function as
1029 many times as it was duplicated.
1031 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1032 from both client and server.
1034 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1036 * Made joining to a channel working in router environment.
1038 * Cleaned up JOIN command on server side and create function
1039 silc_server_command_join_channel internal routine to make the
1042 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1044 * Changed silc_command_pending list to SilcDList. Also, added
1045 `ident' field to SilcServerCommandPending structure to identify
1046 the reply and to call correct callback.
1048 Added silc_server_command_pending_check function to replace the
1049 corresnponding macro. The silc_command_pending list is not
1052 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1053 to set identifier to previously allocated Command Payload. It
1054 is used to set identifier for command when resending Command
1057 * Added silc_command_payload_encode_payload to encode Command
1058 Payload buffer from SilcCommandPayload structure.
1060 * Added silc_argument_payload_encode_payload to encode Argument
1061 payload buffer from SilcArgumentPayload structure.
1063 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1065 * Changed WHOIS command to support router connection on server side.
1066 The whois request is always sent to router unless the server is
1067 standalone server. After server has received the reply from the
1068 router will it send the reply to the client.
1070 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1071 broadcast received broadcast packet. The function is used only
1072 by router. The broadcast packet is always sent to the router's
1075 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1076 render given ID to printable string, for log files for example.
1078 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * Made basic router to router connections working. At least they
1081 can now connect to each other but nothing really works the way
1082 they are supposed - yet.
1084 * Added new initiator token to RouterConnection configuration
1085 file in silcd/serverconfig.[ch]. It is used to tell whether we
1086 are the initiator to the remote router or whether we'll expect
1087 the other end to connect.
1089 * Moved registering of listener task to silc_server_init, hence
1090 the server starts listenning as soon as it is run, even if it
1091 does not have connections to other routers. Let's see how well
1094 * Changed default connection retry timeouts for more suitable in
1097 * Removed cipher and such arguments from silc_idlist_add_client
1098 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1099 Added new function silc_idlist_add_data to add the keys and stuff
1102 * Added SilcIDListData structure and added it to SilcClientEntry
1103 and SilcServerEntry as their first field in the structure. This
1104 way we can explicitly cast the ID entries to the SilcIDListData
1105 structure and get common data for the entries. In past, we had
1106 to first check what type of connection it is and then cast it to
1107 correct ID entry type. Now, we can directly cast the opaque
1108 pointer to the SilcIDListData (no matter what ID entry it actually
1109 is) and get the data needed.
1111 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1113 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1114 in some circumstances even if threre were timeout tasks, though not
1115 IO tasks, but tasks anyway. Now fixed.
1117 * Defined SilcServerConnection structure to hold connection specific
1118 stuff about directly connected servers and routers. The definition
1119 is currently in silcd/server_internal.h. I thought about having
1120 a bit more important role fro this struct but for now it is used
1121 only when connecting to other server (or router actually).
1123 * Added connecting retry support in server when connecting to
1124 router(s). The retry feature implement exponential backoff
1125 algorithm. Also, added SilcServerParams structure to hold default
1126 parameters for server. For now, it include these retry settings
1127 and are hard coded. After server is moded to be as Silc Server
1128 Library this structure will be more important.
1130 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1132 * Changed client librarys channel->clients table to SilcList and
1133 changed code accordingly.
1135 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Changed client's channel table to SilcList and changed code
1138 accordingly. Also changed SilcChannelClientEntry to include back-
1139 pointer to the channel so that client entry can use that structure
1140 as list as well and we have fast cross-reference to the channel.
1141 This change dramatically decreased the complexity of channel
1142 handling with client entry and vice versa (removed one extra
1143 loop when searching for channel entry from many functions).
1145 * Changed server->sim from table to SilcDList and changed code
1148 * NAMES command can now be used from user interface. It will show
1149 the user list on the channel, neatly.
1151 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1152 Code now saves realname of the user if it becomes available.
1154 * Renamed configure.in to configure.in.pre and made ./prepare
1155 script to automatically add correct version string to
1156 configure.in which it creates from configure.in.pre.
1158 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * NAMES command reply now shows users mode with the nickname when
1163 * Moved silc_client_ch[u]mode[_char] functions from
1164 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1165 place sucks, they are utility functions and should be in some
1168 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1170 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1173 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1177 * Added TRQ (efficient deque and list library) into lib/trq. This is
1178 a very good list library that is currently used in the SILC. Defined
1179 SilcList API over the library because I didn't like the API very
1180 much. See lib/trq/silclist.h for the API and examples of how to
1181 use the API. Fixed various places in the code to use the new
1182 SilcList API. The SilcList is meant for lists that has a structure
1183 already defined as a list. It is not suitable to add just some
1184 context to the list (in TRQ, the context is the list actually).
1186 So, I defined SilcDList that can be used for the purpose where
1187 predefined list structure does not exit. This can be used as
1188 such list. Now some context just can be added to the SilcDList.
1189 Currently this list is not used in the SILC just yet, though there
1190 are a lot places where this can replace dynamically allocated
1191 tables and I will fix these places, later, to use SilcDList.
1192 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1193 and use TRQ internally).
1195 Also fixed some annoying warning messages that the original TRQ
1196 code generated. Also minor changes to TRQ's Makefile.in.
1198 * Added support for querying by Client ID to both WHOIS and
1199 IDENTIFY commands into server, as required by the protocol.
1201 * Removed method function pointers from SilcBuffer structure. They
1202 weren't used to anything and just increased the context size for
1203 no good reason. This change also made silc_buffer_alloc and
1204 silc_buffer_free functions inline functions.
1206 * Disabled command flooding detection support until it's fixed so
1207 that it accepts commands in but does not execute them more than once
1210 * Added silc_net_localhost(), to return local hostname, into
1211 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1212 that must be initialized before calling silc_client_init.
1214 * Added new function: silc_server_send_notify_on_channels to send
1215 notify messages to all channels client has joined. It is assured
1216 that the message is sent only once per client.
1218 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1219 lib/silcutil/silcutil.[ch] as silc_format function. The new
1220 function is generic and is used by server as well, not only by
1221 the logging routines.
1223 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1224 the provided version string was not acceptable. Added new function:
1225 silc_ske_check_version into lib/silcske/silcske.h. The function
1226 must be implemented by the application (client or server) and it
1227 does not reside in the SKE library. The function checks the version
1228 string remote end sent.
1230 * Added back pointers (to opaque context and to SilcSocketConnection)
1231 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1233 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1234 duplicate packet context structure.
1236 * Changed `notify' client operation to send same arguments as client
1237 receives from server except for ID's. ID's are mapped to correct
1238 ID entry and that is returned. Also, if channel entry is not sent
1239 by server but the notify is for channel the channel entry is sent
1240 to application (otherwise application doesn't know that it is for
1241 channel (library gets it from packet's Destination ID)).
1243 * Added silc_client_remove_from_channels into client library to
1244 remove a client from all channels it has joined to. Used when
1245 received SIGNOFF notify from server. Added also new function
1246 silc_client_replace_from_channels to replace old ID entry with
1247 new ID entry on all channels. Used when received NICK_CHANGE
1250 * Fixed ID Cache list handling in silc_idlist_get_client in
1251 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1252 to get (or query) client by ID.
1254 * Updated TODO list.
1256 * Added connection authentication status message defined by the
1257 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1258 support for these into the code in client and server side.
1260 * Added generic function silc_client_send_command to send any command
1261 with variable argument list. Application should use this function
1262 to send commands if the command functions provided by the library
1263 does not suite for the application's user interface needs.
1265 * Added new `failure' client operation. Application is notified about
1266 received failure packet if client is executing a protocol. In this
1267 case the protocol's execution has failed.
1269 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1270 is required by the protocol.
1272 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1273 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1276 * Added status flag to SilcSKE object to indicate realtime status
1277 of the SKE protocol.
1279 * Application receives now exactly same command reply arguments as
1280 the library receives from server. However, if ID is received the
1281 corresponding ID entry is returned to the application (eg. Client
1282 ID is mapped to correct SilcClientEntry entry and that is returned).
1283 Changed command_reply client operation due to this change.
1285 * Changed all ID's in commands and in command replys as ID Payloads.
1286 Change affected both client and server side codes.
1288 All ID's sent in SILC network (with execption of ID's in SILC
1289 Packet header) are sent in ID Payload to support variable length
1292 * Server now notifies nick changes and notifies all clients on
1293 the channels about the new nickname (about the new Client ID,
1296 * Implemented CMODE command to change channel modes. Supports all
1297 channel modes defined by the protocol specs except ban and invite
1298 lists. (Also, private channel key mode is supported but support for
1299 setting private channel key in client is missing, thus, this mode
1300 has no effect on client side (except that server requires that the
1301 client uses private channel key and normal channel traffic does not
1304 Also, invite mode works per se, but INVITE command does not work
1305 yet correctly, so you can set channel as invite only channel but
1306 inviting clients to the channel does not work (it is yet to be
1307 thought what's the best way to do it).
1309 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1310 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1311 Implemented CUMODE command to change user's mode on the channel.
1312 Supports all modes defined by the protocol specs.
1314 * Added NAMES command reply to return users modes on the channel.
1316 * Removed unnecessary and slow ciphers from lib/silccrypt.
1318 * Set SO_KEEPALIVE option to connection sockets by default.
1320 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1322 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1323 redefined the Notify Payload into protocol specs.
1325 * Added silc_id_payload_parse_id to get ID directly from raw
1328 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1330 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1331 accept searching by Client ID as well.
1333 * Added support for LEAVE and SIGNOFF notify types in client library.
1335 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1336 to parse ID Payload from raw data.
1338 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1340 * Added flags parameter into silc_ske_assemble_security_properties
1341 function in lib/silcske/silcske.[ch].
1343 * Changed notify client operation to fit better for notify messages
1344 sent by server. The notify payload received from server is now
1345 passed to the application (after parsing it to SilcNotifyPayload).
1346 It is application's responsibility to retrieve the arguments
1347 from the payload and show the message the way it wants. The message
1348 sent by server is implementation specific.
1350 * Changed public keys to comply with the protocol specification.
1351 Old public keys are not supported anymore and are not compatible.
1353 * Removed nickname from Channel Payload as the latest draft removed
1354 it. The client must resolve the nickname from the NAMES command
1355 reply received when it joined the channel.
1357 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1359 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1361 * Fixed some errors in protocol specification drafts.
1363 * Created lib/silccore/silcnotify.c to implement Notify Payload
1364 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1365 generic payloads described by protocol specifications. The file
1366 includes implementations for ID Payload and Argument Payload.
1368 * Changed Command Payload implementation to use the new Argument
1369 Payload. Changed command_xxxx_payload to command_payload_xxxx
1370 to comply with SILC coding conventions.
1372 * Added suppport for Argument Payload handling in Notify Payload
1373 implementation as protocol requires it. Added the new support
1374 into server and client lib as well.
1376 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1378 * Added support for multiple nicknames on same channel. [n] is
1379 added locally to the nickname if there are more than one same
1380 nicknames on the channel.
1382 * Server now sends all nicknames that matched WHOIS request.
1383 Client also shows the list received from server.
1385 * Added TOPIC command to client side. User can now set and show
1386 current topic on channel.
1388 * Added MOTD command to client and server. Also, server sends the
1389 motd when client connects to the server.
1391 * Changed version strings to comply ISO 8601.
1393 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Fixed protocol error handling in client library. It should now
1396 cope even if the SKE fails for some reason.
1398 * Made new protocol specification drafts for submitting to IETF.
1400 * Implemented TOPIC command to server in silcd/command.c.
1402 * Added two new notify types into lib/silccore/silcnotify.h:
1403 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1404 notify nickname change and topic setting/change on a channel.
1406 * API change of command_reply operation in client library. The
1407 application gets now the status type received from server as well.
1409 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1411 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1413 * Cras fixed and optimized the packet handling even further and
1414 it should work now. Minor change to the prototype of function
1415 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1417 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Added new function into lib/silcutil/silcschedule.[ch]:
1420 silc_schedule_with_fd to select() a specified fd. The function
1421 returns after timeout expires or data arrives or goes. The
1422 function is used by packet routines to wait that all data is
1423 received from network.
1425 * Fixed data reading from network in lib/silccore/silcpacket.c.
1426 The code now assures that all data is read from the fd and then
1427 continues packet processing. This was a bug fix since the code
1428 used to drop some data in some circumstances.
1430 * Added new function into lib/silcclient/client.[ch]:
1431 silc_client_start_key_exchange to start key exchange after
1432 connection has been established to server. The code internally
1433 now uses this funtion but its main purpose was to provide it
1434 for applications that perform their own connecting. After
1435 application has created a connection it merely calls this
1436 function to start the key exchange between client and server.
1437 The library takes care of everything else after that.
1439 Updated also lib/silcclient/README to explain the usage of
1442 * Do not send to application information that connection has
1443 been established. Application gets notified it by connect
1446 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Applied cras's patch to add silc_schedule_one function. The
1449 function runs scheduler once and returns.
1451 * Fixed the scheduler after cras messed it up. The timeout
1452 handling works now as it's supposed to work.
1454 * Added into lib/silccore/ silcnotify.h to include notify
1455 message types support. Changed silc_server_send_notify*
1456 functions, in server.[ch], to support those new notify types.
1457 Added the support for the notify types into client library,
1458 as well. Added new notify client operation into ops.h in
1461 * Changed silc_server_packet_send_to_channel to send normal
1462 packets instead of just channel message packets. The function
1463 is now used to send the notify packets to channels. It is not
1464 used to send channel message packets anymore, as server never
1467 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1468 va_arg()s as it seems to require it nowadays. I guess, if SILC
1469 is compiled with older va_arg() the new code should work anyway.
1471 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Splitted core library. Core library (lib/silccore) includes
1474 now only SILC protocol specific core (and common) components.
1475 Created new utility library (lib/silcutil) that includes more
1476 generic purpose stuff. The stuff for util library was taken
1477 from the old core library. This was minor and easy split.
1479 * Created SILC Client Library (lib/silcclient) that includes
1480 implementation of the SILC client without user interface. This
1481 was major move from silc/ directory. The code has been changed
1482 so that it is transparent towards the user interface. The
1483 silc/ directory includes now the same user interface as before
1484 and it uses the new client library. Read lib/silcclient/README.
1485 Basicly, the client library performs everything else related
1486 to SILC except user interface handling. Also, configuration
1487 files are considered to be part of user interface and library
1488 does not handle them.
1490 This change also changed a lot of structures, function naming etc.
1491 Most important change was that SilcClientWindow object was
1492 renamed to SilcClientConnection in the client library. Created
1493 also new file lib/silcclient/ops.h. Also added new files
1494 silc/local_command.[ch] and silc/client_ops.[ch].
1496 All these changes were made to make it easier for user interface
1497 designers to create what ever user interface for the SILC client
1500 It is also expected that the server will be moved to lib
1501 directory as well and SILC Server Library will be created;
1502 sometimes in the future.
1504 * Removed Local commands from lib/silccore/silccommand.h as
1505 they are application specific and new client library does not
1506 handle any of those anymore.
1508 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1509 old client implementation in silc/.
1511 * Added support for callback functions in SILC_LOG_* macros.
1512 Application can now set its own callbacks that will be called
1513 instead of using the default functions that will always print
1514 the debug messages to stderr (or stdout). Also, debugging can
1515 now be disabled by setting silc_debug to FALSE and re-enabled by
1516 setting it to TRUE. Note, that logging will still work even
1517 if debugging is disabled.
1519 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1520 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1521 silc_log_reset_debug_callbacks.
1523 * To enable debugging in silc client one must give now -d
1524 option on command line.
1526 * Changed silc_schedule_init to automatically allocate task queues
1527 if they are not allocated before calling it.
1529 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1531 * Added GMP 3.1 into math library.
1533 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1536 a channel in SILC network. The packet is used by servers and
1537 routers to notify other routers that user has left a channel.
1538 This little feature was missing until now. Added the feature
1539 to protocol specification as well.
1541 Added functions: silc_server_send_remove_channel_user and
1542 silc_server_remove_channel_user into server.[ch].
1544 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1545 lib/silccore/silcpacket.h. However, they are not implemented
1548 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1550 * Fixed joining to a channel and sending channel messages
1551 between server and router. The channel message sending should
1552 now work inside a cell.
1554 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Fixed the private message sending between server and router.
1557 The private message sending should now work inside a cell.
1559 * Added silc_server_replace_id into server.[ch] to replace
1560 existing ID in the SILC network.
1562 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1563 and silc_idlist_replace_server_id into idlist.[ch] in server.
1565 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Fixed the server to server connections. Server can again now
1568 connect to router. Router to router connections probably does
1571 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1573 * Added dynamic protocol registering support. Now protocols can
1574 registered and unregistered on the fly. Patch by cras.
1576 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Added lib/contrib directory to hold routines that some platforms
1579 don't have but are needed by SILC.
1581 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1582 into lin/contrib to provide getopt() and getopt_long() for
1583 those who don't have it.
1585 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1587 * Added AWAY command to client. When away message is set and
1588 client receives a private message packet the client automatically
1589 replies to the sender with the away message.
1591 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1592 bug seemed to be the cause of recent problems when compiling
1595 * Added version detection support to SKE protocol specification
1596 and added the new changes to the SKE implementation as well.
1597 There were other minor changes in the SKE protocol as well.
1599 Many changes in lib/silcske/silcske.[ch] and in
1600 lib/silcske/payload.[ch].
1602 * Added ^U functionality, clear input line. Patch from cras.
1604 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1606 * Mainly small bugfixes on core library. Fixed some debugging
1607 logging and buffer overflow in silclog.c.
1609 * Updated config.sub and config.guess on the distribution tree.
1611 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Added command lagging support in server. Client may execute
1614 commands now only once in two seconds.
1616 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Optimized packet reception. MAC computation and checking is now
1619 also more optimized. A lot previously duplicated code is now
1620 used as generic by both client and server.
1622 * Fixed key pair generation in clientutil.c
1624 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1626 * Added into lib/silccore/silcbufutil.[ch] new function;
1627 silc_buffer_realloc.
1629 * Moved generic packet sending/encryption functions to
1630 lib/silccore/silcpacket.[ch] from client and server. Some
1631 rewriting of the functions.
1633 * Moved all generic packet reception/decryption functions to
1634 lib/silccore/silcpacket.[ch] from client and server. The
1635 packet processing is now much cleaner in both client and server.
1636 These were major changes in both client and server.
1638 * Created many common functions in server to do packet sending.
1639 Previously code were duplicated a lot, this has been removed
1642 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1644 * Rewrote major parts of the ID cache system. Don't know
1645 whether it is better now or not but at least the API is more
1648 * Major rewrite on ID cache stuff on client because of the ID
1649 cache API changes. Added idlist.c to client.
1651 * Also major rewrite on ID cache stuff on server as well.
1652 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1653 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1654 in hand, instead they are all put into the ID cache system now.
1655 All server_idlist_* routines uses ID cache now instead of
1656 traversing its own lists (those lists does not exist anymore).
1657 SilcIDList though still exists. Also, SilcXXXEntry's are
1660 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1662 * Finally made the SKE implementation compliant to the protocol
1663 specification. All mp integers are now binary encoded as
1664 opposed being HEX encoded.
1666 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1669 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1670 functions: silc_[encode/decode]_pem. Also added function
1671 silc_encode_pem_file to PEM encode with newlines ('\n') for
1674 * SILC public keys are now encoded either PEM or binary. Same
1675 option is for private keys as well. By default private keys
1676 are binary encoded and public keys PEM encoded. Silly HEX
1677 encoding were removed.
1679 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1680 function to create fingerprints.
1682 * Fixed a bug in SHA1; does not change the original data anymore.
1684 * Partly implemented INFO command on client and server side.
1685 Fixed CLEAR command. Changes to SERVER command; show current
1686 server(s) when giving command without arguments. Added
1687 VERSION command to client.
1689 * Added check to server that unregistered connections cannot
1690 execute commands (unless it is specificly allowed).
1692 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Fixed screen refresh.
1696 * Fixed channel joining bug from client. On some circumstances
1697 client tried to join to a channel it had already joined.
1699 * Added public key verification process into client's protocol.c.
1700 The client now verifies the public key from user and saves
1701 it into ~./silc/serverkeys/ directory.
1703 Added into: clientutil.[ch]: silc_client_verify_server_key.
1705 * Changed SKE protocol's silc_ske_initiator_finish function
1706 to accept callback function that verifies the received public
1707 key. Removed old silc_ske_verify_public_key function.
1709 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1711 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1712 silc_pkcs_private_key[_data]_set.
1714 * Made the password and public authentication more cleaner in
1715 server's protocol.c.
1717 * Removed historic and obsolete protocol `channel_auth' from
1718 both client and server.
1720 * Removed wrong way of sending command status messages from
1721 server to client in server's command.c. The old way violated
1722 protocol specification.
1724 Changes to silccore/silccommand.[ch]: removed
1725 silc_command_encode_status_payload -> not needed anymore,
1726 changed silc_command_encode_payload_va to accept extra
1727 argument on variable argument list. The argument type must
1728 now be provided to the function. Also, added new function:
1729 silc_command_encode_reply_payload_va which is same as
1730 normal command_encode_payload_va except command status type
1731 is provided as extra argument.
1733 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Added ~./silc directory handling. The directory includes the
1736 public and private keys for the client.
1738 Added silc_client_check_silc_dir, silc_client_create_identifier
1739 and silc_client_load_keys.
1741 * Implemented SILC protocol compliant public key. Added public
1742 and private key saving to and loading from files.
1744 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1745 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1746 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1747 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1748 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1750 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1751 silc_pkcs_load_[public/private]_key.
1753 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Added silc_server_get_route (route.[ch]) to get connection
1756 data for the fastest route for given ID.
1758 * Implemented INVITE command on client and server. The command
1759 were re-defined in the SILC Protocol Specification and the
1760 implementation now complies with the specification.
1762 * Implemented PING command on client and server.
1764 * Implemented NAMES command on client and server. The server side
1765 supports currently only normal server not router server yet.
1766 Some changes to NAMES definition in SILC protocol specification.
1768 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1770 * Implemented LEAVE command on client and server.
1772 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1773 again. This change was made to the protocol as well. Server
1774 should not violate the protocol specification anymore.
1776 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1778 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1779 was tested. SOCKS4 was not but should work anyway.
