3 * Made some sanity checks to silc_server_daemonise like to check
4 whether the reuqested user and group actually exists.
6 * Added sanity check to SKE's silc_ske_responder_finish to check
7 that the public and private key actually is valid.
9 * Invalidate the client's nickname when receiving Replace ID
10 packet and the Client ID is being replaced. This means that the
11 server will query the nickname if someone needs it (client)
14 * Sort the ID Cache in client library when the ID Cache data
15 has changed (needs sorting).
17 * Do not allow for SILC client to create several connections to
18 several servers. The client does not support windows right now
19 and generating multiple connections causes weird behaviour.
21 Irssi-silc client does support windows and can handle several
22 connections without problems, see: www.irssi.org and SILC plugin.
24 * Fixed some places where client was added to the IDList. The
25 rule of thumb is following (in order to get everything right):
26 If the client is directly connected local client then the
27 `connection' argument must be set and `router' argument must be
28 NULL to silc_idlist_add_client function. If the client is not
29 directly connected client then the `router' argument must
30 bet set and the `connection' argument must be NULL to the
31 silc_idlist_add_client function.
33 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Added --with-gmp configuration option. If set the GMP
36 is always compiled in the SILC source tree. If not set then
37 it is checked whether the system has the GMP3 installed. If
38 it has then the GMP won't be compiled (the system's headers
39 and library is used), if it doesn't have it then the GMP is
40 compiled in the SILC source tree.
42 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Changed RSA private exponent generation to what PKCS #1
45 suggests. We try to find the smallest possible d by doing
46 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
47 not security fix but optimization.
49 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Added new config entry [Identity] to fork the server and run
52 it as specific user and group. A patch from Bostik.
54 * Imported Dotconf configuration library into lib/dotconf.
55 This will be used to create the SILC configuration files later.
56 It will appear in the distsribution after this commit.
58 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
60 * A big code auditing weekend happening. Auditing code for
61 obvious mistakes, bugs and errors. Also, removing any code
64 Removed files for being obsolete:
66 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
67 inline in the file lib/silcutil/silcbuffer.h)
69 o lib/silcutil/silcbufutil.c (the header has inline versions)
71 Changed code to fix possible error conditions:
73 o The buffer formatting routines now check that the destination
74 buffer really has enough space to add the data. This applies for
75 both buffer formatting and unformatting
76 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
77 unformatting was changed to accomodate following rules:
78 XXX_*STRING_ALLOC will allocate space for the data into the pointer
79 sent to the function while XXX_*STRING will not allocate or copy
80 the data into the buffer. Instead it sets the pointer from the
81 buffer into the pointer sent as argument (XXX_*STRING used to
82 require that the pointer must be allocated already). This change
83 makes this whole thing a bit more consistent and more optimized
84 (note that the data returned in the unformatting with XXX_*STRING
85 must not be freed now). The routines return now -1 on error.
87 o Tried to find all code that use buffer_format and buffer_unformat
88 and added return value checking to prevent formatting and
89 especially unformatting errors and possible subsequent fatal
92 o Changed ske->x and ske->KEY to mallocated pointers in
93 lib/silcske/silcske.h. Fixed possible data and memory leak.
95 o Added return value checking to all *_parse* functions. Fixed
96 many memory leaks as well.
98 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
99 so that buffer overflows would not happen. All code now also
100 checks the return value as it can fail.
102 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
104 * Added reconnection support to server if the normal server looses
105 its connection to the router (for example if router is rebooted).
106 The server performs normal reconnection strategy implemented
107 to the server. Affected file silcd/server.c.
109 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Added new packet type SILC_PACKET_SET_MODE that is used to
112 distribute the information about changed modes (for clients,
113 channels and clients channel modes) to all routers in the
114 network. Updated the protocol specification accordingly.
116 Added functions into silcd/packet_send.c and
117 silcd/packet_receive.c: silc_server_send_set_mode,
118 silc_server_set_mode.
120 Added new files silcmode.[ch] into lib/silccore that implements
121 the encoding and decoding of Set Mode Payload. Added new type
122 SilcSetModePayload. Moved the definitions of different modes
123 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
125 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
127 * Oops, a little mistake in server's connection authentication
128 protocol. The protocol is not ended with FAILURE but with
129 SUCCESS if the authentication is Ok. :) Affected file is
132 * Implemented NICK_CHANGE notify handling in server in the file
133 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
134 the local clients on the channel. After the changing nickname
135 in router environment snhould work and the [<unknown>] nickname
136 should appear no more.
138 The silc_server_replace_id function that receives the Replace ID
139 payload now sends the NICK_CHANGE notify type also in the file
140 silcd/packet_receive.c
142 * Changed WHOIS and IDENTIFY command to support the maximum amount
143 of arguments defined in protocol specs (3328 arguments). This
144 fixed a bug that caused problems when there were more than three
147 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
149 * Added extra parameter, command identifier, to the
150 silc_client_send_command so that explicit command identifier
153 Changed that ID list routines uses specific command identifier
154 when sending WHOIS/IDENTIFY requests to the server so that they
155 can be identified when the reply comes back.
157 Affected files lib/silcclient/command.[ch],
158 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
160 * Added `sender' argument to silc_server_packet_send_to_channel
161 to indicaet the sender who originally sent the packet to us
162 that we are now re-sending. Ignored if NULL. Affected file
163 silcd/packet_send.[ch].
165 * Added some server statistics support in silcd/server_internal.h
166 SilcServerStatistics structure and around the server code. Also
167 send some nice statistics information when client is connecting
170 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * Fixed channel ID decoding in server's JOIN command reply in
173 silcd/command_reply.c
175 * Fixed braodcasting of replace ID payload to not to send it if
176 we are standalone server in silcd/packet_receive.c.
178 * Fixed all channel message sending routines to not to send
179 packets to clients that has router set, since they are routed
180 separately in the same function earlier. Affects file
181 silcd/packet_send.c and all channel packet sending functions.
183 * In USERS reply, res_argv[i] are not allocated, the table
184 is allocated. Thus changed that free the table, not its
187 * In server's whois_check and identify_check if the client is
188 locally connected do not send any WHOIS commands - they are not
191 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Fixed some minor bugs in client when sending WHOIS command. The
194 arguments was in wrong order.
196 * Removed statis function add_to_channel from server in
197 silcd/command.c that was previously used with the joining but
200 * Tested USERS command in router environment successfully with two
201 routers, two servers and two clients.
203 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
205 * Reorganized the USERS command and command reply in client library
206 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
207 When the command is given by user we register a pending command
208 callback that will reprocess the command after the reply has been
209 received from the server. When reprocessing the packet we then
210 display the information. Thus, the USERS information is displayed
211 now in the command callback instead of in the command reply
212 callback. The processing of the command is same as previously
213 when server has sent the command reply in the JOINing process.
215 * Added to USERS command in silcd/command_reply.c to join the client,
216 we didn't use to know about, to the channel after we've created
217 a client entry for it. Also, for clienet we did know already still
218 check whether it is on the channel or not and add it if not.
220 * Removed silc_server_command_join_notify as the function and its
223 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Changed the client's pending command handling to the same as the
226 server's pending command handling. It is also now possible to
227 execute command reply functions from other command reply
228 function as the function callbacks for commands and command
229 replies are one and same. The pending commands are not static
230 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
231 in client connection context. Thus, pending commands are server
232 connection specific as it is convenient.
234 Changed the function silc_client_command_pending and
235 silc_client_command_pending_del and added new function
236 silc_client_command_pending_check. Removed the
237 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
240 * Added cmd_ident, current command identifier, to the client
241 connection context in lib/silcclient/client.h to keep track on
242 command identifiers used in command sending. Client's command reply
243 function handling now supports the mandatory command identifiers.
245 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
246 funtions in client to fully support pending command callbacks.
248 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
249 as one of the arguments to the application in the command reply
252 * NOTE: The FORWARDED flag is depracated. It used to be depracated
253 before first releasing SILC but came back. Now it is removed again
254 and should come back nomore. The FORWARDED flag was used only
255 by the JOINing procedure by forwarding the command packet to router.
256 Now, the JOINing procedure has been changed to more generic (due
257 to various router environment issues) and FORWARDED is not needed
258 anymore for anything. The protocol specification is yet to be
261 Now, removed silc_server_packet_forward from server and the flag
262 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
264 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
266 * Renamed NAMES command to USERS command. The NAMES was named that
267 due to historical reasons. Now it is renamed. Also, rewrote
268 parts of the USERS command. The nickname list is not sent anymore
269 by the server. Only Client ID and mode lists are sent in the USERS
270 command. Changed this also to the protocol specification.
272 The client now resolves the names and stuff after it receives
273 the USERS list from the server when joining to the channel.
275 * WHOIS and IDENTIFY commands has been changed to support multiple
276 Client ID's per command. One can now search for multiple users
277 in the network by sending only one WHOIS or IDENTIFY command.
278 Changed the code and the protocol specifications.
280 * Removed silc_server_command_identify_parse and changed that IDENTIFY
281 uses silc_server_command_whois_parse to parse the request. */
283 * If normal server, do not parse the WHOIS and IDENTIFY requests
284 before sending it to the router. Saves some time.
286 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Fixed JOIN command on client library. Wrong number of arguments
289 used to crash the client.
291 * Added silc_server_channel_has_global function to check whether
292 channel has global users or not.
294 * Added silc_server_channel_has_local function to check whether channel
295 has locally connected clients on the channel.
297 * The silc_server_remove_from_one_channel now checks whether the
298 channel has global users or not after given client was removed from
299 the channel. It also checks whether the channel has local clients
300 on the channel anymore. If it does not have then the channel entry
301 is removed as it is not needed anymore.
303 * The silc_server_notify now checks on JOIN notify whether the joining
304 client is one of locally connected or global. If it is global then
305 the channel has now global users on the channel and that is marked
306 to the channel entry. Also, it now saves the global client to
307 global list who is joining and JOINs it to the channel. This is
308 for normal server, that is.
310 Changed silc_server_send_notify_on_channel,
311 silc_server_packet_relay_to_channel and
312 silc_server_packet_send_to_channel check if we are normal server
313 and client has router set (ie. global client) do not send the
314 message to that client, as it is already routed to our router.
316 * Implemented LEAVE notify type handling in silc_server_notify
319 * Tested LEAVE command in router environment successfully. Tested
320 with two routers, two servers and two clients.
324 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
326 * Implemented SIGNOFF notify type handling in silc_server_notify
329 * silc_server_remove_id now removes the client entry from all channels
330 it has joined and thusly sends SIGNOFF notify type.
332 * Rewrote the NAMES list generation in server by removing two excess
333 loops. The lists are created now inside one loop.
335 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
337 * silc_server_remove_channel_user checks now also global list
338 for channel and client.
340 * silc_server_new_channel_user checks now both local and global
341 list for channel and client. Fixed a bug in client id decoding.
342 Used to decode wrong buffer.
344 * silc_server_channel_message checks now both local and global
345 list for channel entry.
347 * Tested channel joining (hence JOIN) in router environment
348 successfully. Tested with two routers, two servers and two
351 * Tested channel message sending in router environment successfully.
353 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
355 * Added silc_server_save_channel_key into server.[ch] to save the
356 received channel key in Channel Key payload processing. It is
357 also used in JOIN command reply handling.
359 Equivalent function silc_client_save_channel_key added into
360 client.[ch] into client library.
362 * Changed JOIN command reply to send information whether the channel
363 was created or not (is existing already) and the channel key
364 payload. Changed protocol specs accordingly.
366 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
367 the request was sent by ID and not by nickname. Crashed on
370 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
373 now correctly save the received data.
375 * silc_server_free_sock_user_data now notifies routers in the
376 network about entities leaving the network.
378 At the same time implemented functions silc_server_remove_id
379 and silc_server_send_remove_id to receive and send REMOVE_ID
380 packets. The packet is used to notify routers in the network
381 about leaving entities. The ID removed will become invalid in
384 * Added function silc_idlist_del_server into server. Removes and
385 free's server entry from ID list.
387 * silc_server_private_message function now checks, if we are router,
388 that the destination ID really is valid ID, naturally.
390 * In router when NEW_ID packet is received (for new client) the
391 hash of the Client ID is saved in the ID Cache but the
392 client->nickname is set to NULL, instead of putting the hash
395 IDENTIFY command now also checks that client->nickname must be
396 valid. If it is not if will request the data from the server who
397 owns the client. Added new function
398 silc_server_command_identify_check.
400 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
401 to set the command to already allocated Command Payload.
403 * Tested private message sending in router environment with two
404 routers, two servers and two clients. Fixed minor bugs and now
407 * Fixed segfault from client's NAMES command. Used to crash if
410 * Forwarded packets must not be routed even if it is not destined
411 to the receiver. Changed server code comply with this.
413 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Added `require_reverse_mapping' boolean value to ServerParams
416 structure. If TRUE (not default) the server will require that
417 the connecting host has fully qualified domain name.
419 If the reverse mapping is not required and hostname could not be
420 found the IP address is used as hostname.
422 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
424 * Implemented version string checking to both client and server.
425 The check is incomplete currently due to the abnormal version
426 strings used in development version of SILC.
428 * Changed all command functions in server to use the new
431 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Changed char *data to unsigned char *data in ID Cache system to
434 support binary data as ID Cache data. Changed code to support
435 binary data in lib/silccore/idcache.c.
437 * Renamed silc_server_packet_relay_command_reply to
438 silc_server_command_reply as it is normal packet receiving
439 function. Rewrote the function to accept command replys for
440 servers and not only for clients.
442 * Mark remote router always as registered server if we are connecting
443 to it. Otherwise, commands sent by the router to us are ignored.
445 * All ID List find routines now returns the ID Cache Entry pointer
446 as well if requested.
448 * WHOIS command works now in router environment, tested with two
449 routers, two servers and two clients.
451 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
452 in router environment (as it is almost equivalent to WHOIS) but
453 hasn't been tested thoroughly. Added new functions:
455 silc_server_command_identify_parse
456 silc_server_command_identify_send_reply
457 silc_server_command_identify_from_client
458 silc_server_command_identify_from_server
460 * Disabled route cache adding because adding two different ID's with
461 same IP replaces the old cache entry thus giving wrong route.
462 The entry->router->connection is always the fastest route anyway
463 so route cache may not be needed. Of course, new routes maybe
464 established after receiving the ID when the entry->router->connection
465 might not be anymore the most optimal.
467 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
469 * Add route cache for received ID for fast routing.
471 * Added silc_server_packet_route to route received packet on router
472 that is not destined to us.
474 * Renamed silc_server_get_route to silc_server_route_get.
476 * Added id_string and id_string_len fields into SilcServer to
477 include encoded ServerID for fast comparing without excess
478 encoding of the ID's.
480 * Cleaned up WHOIS command on server side. Added following static
483 silc_server_command_whois_parse
484 silc_server_command_whois_check
485 silc_server_command_whois_send_reply
486 silc_server_command_whois_from_client
487 silc_server_command_whois_from_server
489 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
490 arguments in command replies. All command functions should be
491 updated to use this macro.
493 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
495 * Minor typo fixes on command reply handling on server.
497 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
499 * Added silc_server_command_add_to_channel internal routine to add
500 the client to the channel after router has created the channel and
501 sent command reply to the server.
503 * Added generic silc_server_send_command to send any command from
506 * Use static buffer with ID rendering instead of duplicating data.
508 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Fixed a channel user mode bug when joining to a channel server gave
511 everybody channel founder rights, oops.
513 * We mark ourselves as the router of the incoming server connection
514 if we are router ourselves. This way we can check in some packet
515 sending functions whether it is locally connected server. For
516 incoming router connections we put NULL.
518 * For router sending packets locally means now always sending the
519 packet cell wide; to local clients and local servers. For normal
520 server sending packet locally means sending it to only local
523 * Fixed the JOIN command to really work in router environment. If the
524 channel is created it is always created by the router. Router is
525 also responsible of making the initial joining to the channel,
526 sending JOIN notify to the sending server and distributing
527 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
528 does not exist server doesn't do anything else but forward the
529 command to the router which performs everything.
531 * Added silc_server_send_channel_key function to send the Channel Key
534 * Added silc_server_create_channel_key to create new channel key. The
535 channel key is now re-generated everytime someone joins or leaves
536 a channel, as protocol dictates. Note: channel->key_len is the
539 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
541 * Splitted server.[ch] finally. Created now packet_send.[ch] and
542 packet_receive.[ch] to separate packet sending and receiving
543 routines. The server.[ch] now includes everything else including
544 actual packet processing (writing and reading data) and other
547 Renamed silc_server_private_message_send_internal to
548 silc_server_send_private_message. The routine is still though
549 used only to relay private messages as server does not send
550 private messages itself.
552 Renamed silc_server_new_channel to silc_server_create_new_channel
553 and added new function sicl_server_new_channel that handles the
554 incoming New Channel packet. Added also new sending function
555 silc_server_send_new_channel to send New Channel Payload.
557 * Added new function silc_server_notify to process incoming notify
558 packet to the server/router. Server may then relay the notify
559 to clients if needed.
561 * Added new function silc_server_new_channel_user to process incoming
562 New Channel User packet. Router will redistribute the packet and
563 send JOIN notify to its local clients and locally connected servers
564 if needed. Normal server will send JOIN notify to its local client
565 on same channel when received this packet. Added also corresponding
566 sending function silc_server_send_new_channel_user to sent the
569 * Added boolean route argument to send_notif_to_channel and
570 packet_send_to_channel functions to attempt to route the packet
571 if it is TRUE and send only locally if it is FALSE.
573 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * silc_server_replace_id now broadcasts the received replace ID
576 packet if it is not broadcast packet already. The router must
577 broadcast to inform other routers about changed ID.
579 * Added backpointer to server's router into SilcServer context in
580 silcd/server_internal.h.
582 * Fixed silc_server_packet_broadcast to send correct broadcast
585 * The channel key is now distributed to the local client as soon
586 as it is received from the router (in router environment) so that
587 no other packet may be sent for the channel until client has
590 * silc_server_remove_channel_user now broadcasts the received
591 Remove Channel User packet if it is not broadcast packet already.
592 The router must broadcast to inform other routers about removed
595 * Added users field into SilcPacketContext that is a reference count
596 of the context. One can increase the reference count by calling
597 silc_packet_context_dup which is now changed to just increase the
598 reference count instead of duplicating the data. The reference
599 count is decresed by calling silc_packet_context_free that will
600 free the data after the reference count hits zero.
602 For now on the packet context and everything allocated into it
603 (including the raw packet from network) must be freed by calling
604 the new silc_packet_context_free function. Added also new function
605 silc_packet_context_alloc that must be used now to allocate the
606 context. This also means that if a routine is asynchronous from
607 silc_[client/server]_packet_parse_type the packet context must
608 be duplicated by calling silc_packet_context_dup. Otherwise it
609 gets free'd after silc_[client/server]_packet_parse_type returns.
610 Also, one must remember that if packet is duplicated then its
611 reference count must be decresed by calling the free function as
612 many times as it was duplicated.
614 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
615 from both client and server.
617 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Made joining to a channel working in router environment.
621 * Cleaned up JOIN command on server side and create function
622 silc_server_command_join_channel internal routine to make the
625 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
627 * Changed silc_command_pending list to SilcDList. Also, added
628 `ident' field to SilcServerCommandPending structure to identify
629 the reply and to call correct callback.
631 Added silc_server_command_pending_check function to replace the
632 corresnponding macro. The silc_command_pending list is not
635 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
636 to set identifier to previously allocated Command Payload. It
637 is used to set identifier for command when resending Command
640 * Added silc_command_payload_encode_payload to encode Command
641 Payload buffer from SilcCommandPayload structure.
643 * Added silc_argument_payload_encode_payload to encode Argument
644 payload buffer from SilcArgumentPayload structure.
646 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
648 * Changed WHOIS command to support router connection on server side.
649 The whois request is always sent to router unless the server is
650 standalone server. After server has received the reply from the
651 router will it send the reply to the client.
653 * Added silc_server_packet_broadcast into silcd/server.[ch] to
654 broadcast received broadcast packet. The function is used only
655 by router. The broadcast packet is always sent to the router's
658 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
659 render given ID to printable string, for log files for example.
661 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Made basic router to router connections working. At least they
664 can now connect to each other but nothing really works the way
665 they are supposed - yet.
667 * Added new initiator token to RouterConnection configuration
668 file in silcd/serverconfig.[ch]. It is used to tell whether we
669 are the initiator to the remote router or whether we'll expect
670 the other end to connect.
672 * Moved registering of listener task to silc_server_init, hence
673 the server starts listenning as soon as it is run, even if it
674 does not have connections to other routers. Let's see how well
677 * Changed default connection retry timeouts for more suitable in
680 * Removed cipher and such arguments from silc_idlist_add_client
681 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
682 Added new function silc_idlist_add_data to add the keys and stuff
685 * Added SilcIDListData structure and added it to SilcClientEntry
686 and SilcServerEntry as their first field in the structure. This
687 way we can explicitly cast the ID entries to the SilcIDListData
688 structure and get common data for the entries. In past, we had
689 to first check what type of connection it is and then cast it to
690 correct ID entry type. Now, we can directly cast the opaque
691 pointer to the SilcIDListData (no matter what ID entry it actually
692 is) and get the data needed.
694 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Wow, found a bug in scheduler. The scheduler uninitialized itself
697 in some circumstances even if threre were timeout tasks, though not
698 IO tasks, but tasks anyway. Now fixed.
700 * Defined SilcServerConnection structure to hold connection specific
701 stuff about directly connected servers and routers. The definition
702 is currently in silcd/server_internal.h. I thought about having
703 a bit more important role fro this struct but for now it is used
704 only when connecting to other server (or router actually).
706 * Added connecting retry support in server when connecting to
707 router(s). The retry feature implement exponential backoff
708 algorithm. Also, added SilcServerParams structure to hold default
709 parameters for server. For now, it include these retry settings
710 and are hard coded. After server is moded to be as Silc Server
711 Library this structure will be more important.
713 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
715 * Changed client librarys channel->clients table to SilcList and
716 changed code accordingly.
718 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Changed client's channel table to SilcList and changed code
721 accordingly. Also changed SilcChannelClientEntry to include back-
722 pointer to the channel so that client entry can use that structure
723 as list as well and we have fast cross-reference to the channel.
724 This change dramatically decreased the complexity of channel
725 handling with client entry and vice versa (removed one extra
726 loop when searching for channel entry from many functions).
728 * Changed server->sim from table to SilcDList and changed code
731 * NAMES command can now be used from user interface. It will show
732 the user list on the channel, neatly.
734 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
735 Code now saves realname of the user if it becomes available.
737 * Renamed configure.in to configure.in.pre and made ./prepare
738 script to automatically add correct version string to
739 configure.in which it creates from configure.in.pre.
741 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
743 * NAMES command reply now shows users mode with the nickname when
746 * Moved silc_client_ch[u]mode[_char] functions from
747 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
748 place sucks, they are utility functions and should be in some
751 * Fixed some unsigned int's to unsigned short's. Patch by cras.
753 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
756 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
760 * Added TRQ (efficient deque and list library) into lib/trq. This is
761 a very good list library that is currently used in the SILC. Defined
762 SilcList API over the library because I didn't like the API very
763 much. See lib/trq/silclist.h for the API and examples of how to
764 use the API. Fixed various places in the code to use the new
765 SilcList API. The SilcList is meant for lists that has a structure
766 already defined as a list. It is not suitable to add just some
767 context to the list (in TRQ, the context is the list actually).
769 So, I defined SilcDList that can be used for the purpose where
770 predefined list structure does not exit. This can be used as
771 such list. Now some context just can be added to the SilcDList.
772 Currently this list is not used in the SILC just yet, though there
773 are a lot places where this can replace dynamically allocated
774 tables and I will fix these places, later, to use SilcDList.
775 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
776 and use TRQ internally).
778 Also fixed some annoying warning messages that the original TRQ
779 code generated. Also minor changes to TRQ's Makefile.in.
781 * Added support for querying by Client ID to both WHOIS and
782 IDENTIFY commands into server, as required by the protocol.
784 * Removed method function pointers from SilcBuffer structure. They
785 weren't used to anything and just increased the context size for
786 no good reason. This change also made silc_buffer_alloc and
787 silc_buffer_free functions inline functions.
789 * Disabled command flooding detection support until it's fixed so
790 that it accepts commands in but does not execute them more than once
793 * Added silc_net_localhost(), to return local hostname, into
794 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
795 that must be initialized before calling silc_client_init.
797 * Added new function: silc_server_send_notify_on_channels to send
798 notify messages to all channels client has joined. It is assured
799 that the message is sent only once per client.
801 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
802 lib/silcutil/silcutil.[ch] as silc_format function. The new
803 function is generic and is used by server as well, not only by
804 the logging routines.
806 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
807 the provided version string was not acceptable. Added new function:
808 silc_ske_check_version into lib/silcske/silcske.h. The function
809 must be implemented by the application (client or server) and it
810 does not reside in the SKE library. The function checks the version
811 string remote end sent.
813 * Added back pointers (to opaque context and to SilcSocketConnection)
814 into SilcPacketContext structure into lib/silccore/silcpacket.h.
816 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
817 duplicate packet context structure.
819 * Changed `notify' client operation to send same arguments as client
820 receives from server except for ID's. ID's are mapped to correct
821 ID entry and that is returned. Also, if channel entry is not sent
822 by server but the notify is for channel the channel entry is sent
823 to application (otherwise application doesn't know that it is for
824 channel (library gets it from packet's Destination ID)).
826 * Added silc_client_remove_from_channels into client library to
827 remove a client from all channels it has joined to. Used when
828 received SIGNOFF notify from server. Added also new function
829 silc_client_replace_from_channels to replace old ID entry with
830 new ID entry on all channels. Used when received NICK_CHANGE
833 * Fixed ID Cache list handling in silc_idlist_get_client in
834 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
835 to get (or query) client by ID.
839 * Added connection authentication status message defined by the
840 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
841 support for these into the code in client and server side.
843 * Added generic function silc_client_send_command to send any command
844 with variable argument list. Application should use this function
845 to send commands if the command functions provided by the library
846 does not suite for the application's user interface needs.
848 * Added new `failure' client operation. Application is notified about
849 received failure packet if client is executing a protocol. In this
850 case the protocol's execution has failed.
852 * Added SKE's end notify to send the SKE_SUCCESS notify message that
853 is required by the protocol.
855 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
856 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
859 * Added status flag to SilcSKE object to indicate realtime status
862 * Application receives now exactly same command reply arguments as
863 the library receives from server. However, if ID is received the
864 corresponding ID entry is returned to the application (eg. Client
865 ID is mapped to correct SilcClientEntry entry and that is returned).
866 Changed command_reply client operation due to this change.
868 * Changed all ID's in commands and in command replys as ID Payloads.
869 Change affected both client and server side codes.
871 All ID's sent in SILC network (with execption of ID's in SILC
872 Packet header) are sent in ID Payload to support variable length
875 * Server now notifies nick changes and notifies all clients on
876 the channels about the new nickname (about the new Client ID,
879 * Implemented CMODE command to change channel modes. Supports all
880 channel modes defined by the protocol specs except ban and invite
881 lists. (Also, private channel key mode is supported but support for
882 setting private channel key in client is missing, thus, this mode
883 has no effect on client side (except that server requires that the
884 client uses private channel key and normal channel traffic does not
887 Also, invite mode works per se, but INVITE command does not work
888 yet correctly, so you can set channel as invite only channel but
889 inviting clients to the channel does not work (it is yet to be
890 thought what's the best way to do it).
892 * Added new command SILC_COMMAND_CUMODE to change user mode on the
893 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
894 Implemented CUMODE command to change user's mode on the channel.
895 Supports all modes defined by the protocol specs.
897 * Added NAMES command reply to return users modes on the channel.
899 * Removed unnecessary and slow ciphers from lib/silccrypt.
901 * Set SO_KEEPALIVE option to connection sockets by default.
903 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
905 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
906 redefined the Notify Payload into protocol specs.
908 * Added silc_id_payload_parse_id to get ID directly from raw
911 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
913 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
914 accept searching by Client ID as well.
916 * Added support for LEAVE and SIGNOFF notify types in client library.
918 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
919 to parse ID Payload from raw data.
921 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Added flags parameter into silc_ske_assemble_security_properties
924 function in lib/silcske/silcske.[ch].
926 * Changed notify client operation to fit better for notify messages
927 sent by server. The notify payload received from server is now
928 passed to the application (after parsing it to SilcNotifyPayload).
929 It is application's responsibility to retrieve the arguments
930 from the payload and show the message the way it wants. The message
931 sent by server is implementation specific.
933 * Changed public keys to comply with the protocol specification.
934 Old public keys are not supported anymore and are not compatible.
936 * Removed nickname from Channel Payload as the latest draft removed
937 it. The client must resolve the nickname from the NAMES command
938 reply received when it joined the channel.
940 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
942 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Fixed some errors in protocol specification drafts.
946 * Created lib/silccore/silcnotify.c to implement Notify Payload
947 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
948 generic payloads described by protocol specifications. The file
949 includes implementations for ID Payload and Argument Payload.
951 * Changed Command Payload implementation to use the new Argument
952 Payload. Changed command_xxxx_payload to command_payload_xxxx
953 to comply with SILC coding conventions.
955 * Added suppport for Argument Payload handling in Notify Payload
956 implementation as protocol requires it. Added the new support
957 into server and client lib as well.
959 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * Added support for multiple nicknames on same channel. [n] is
962 added locally to the nickname if there are more than one same
963 nicknames on the channel.
965 * Server now sends all nicknames that matched WHOIS request.
966 Client also shows the list received from server.
968 * Added TOPIC command to client side. User can now set and show
969 current topic on channel.
971 * Added MOTD command to client and server. Also, server sends the
972 motd when client connects to the server.
974 * Changed version strings to comply ISO 8601.
976 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Fixed protocol error handling in client library. It should now
979 cope even if the SKE fails for some reason.
981 * Made new protocol specification drafts for submitting to IETF.
983 * Implemented TOPIC command to server in silcd/command.c.
985 * Added two new notify types into lib/silccore/silcnotify.h:
986 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
987 notify nickname change and topic setting/change on a channel.
989 * API change of command_reply operation in client library. The
990 application gets now the status type received from server as well.
992 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Removed the function just added to lib/silcutil/silcschedule.[ch].
996 * Cras fixed and optimized the packet handling even further and
997 it should work now. Minor change to the prototype of function
998 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1000 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Added new function into lib/silcutil/silcschedule.[ch]:
1003 silc_schedule_with_fd to select() a specified fd. The function
1004 returns after timeout expires or data arrives or goes. The
1005 function is used by packet routines to wait that all data is
1006 received from network.
1008 * Fixed data reading from network in lib/silccore/silcpacket.c.
1009 The code now assures that all data is read from the fd and then
1010 continues packet processing. This was a bug fix since the code
1011 used to drop some data in some circumstances.
1013 * Added new function into lib/silcclient/client.[ch]:
1014 silc_client_start_key_exchange to start key exchange after
1015 connection has been established to server. The code internally
1016 now uses this funtion but its main purpose was to provide it
1017 for applications that perform their own connecting. After
1018 application has created a connection it merely calls this
1019 function to start the key exchange between client and server.
1020 The library takes care of everything else after that.
1022 Updated also lib/silcclient/README to explain the usage of
1025 * Do not send to application information that connection has
1026 been established. Application gets notified it by connect
1029 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Applied cras's patch to add silc_schedule_one function. The
1032 function runs scheduler once and returns.
1034 * Fixed the scheduler after cras messed it up. The timeout
1035 handling works now as it's supposed to work.
1037 * Added into lib/silccore/ silcnotify.h to include notify
1038 message types support. Changed silc_server_send_notify*
1039 functions, in server.[ch], to support those new notify types.
1040 Added the support for the notify types into client library,
1041 as well. Added new notify client operation into ops.h in
1044 * Changed silc_server_packet_send_to_channel to send normal
1045 packets instead of just channel message packets. The function
1046 is now used to send the notify packets to channels. It is not
1047 used to send channel message packets anymore, as server never
1050 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1051 va_arg()s as it seems to require it nowadays. I guess, if SILC
1052 is compiled with older va_arg() the new code should work anyway.
1054 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1056 * Splitted core library. Core library (lib/silccore) includes
1057 now only SILC protocol specific core (and common) components.
1058 Created new utility library (lib/silcutil) that includes more
1059 generic purpose stuff. The stuff for util library was taken
1060 from the old core library. This was minor and easy split.
1062 * Created SILC Client Library (lib/silcclient) that includes
1063 implementation of the SILC client without user interface. This
1064 was major move from silc/ directory. The code has been changed
1065 so that it is transparent towards the user interface. The
1066 silc/ directory includes now the same user interface as before
1067 and it uses the new client library. Read lib/silcclient/README.
1068 Basicly, the client library performs everything else related
1069 to SILC except user interface handling. Also, configuration
1070 files are considered to be part of user interface and library
1071 does not handle them.
1073 This change also changed a lot of structures, function naming etc.
1074 Most important change was that SilcClientWindow object was
1075 renamed to SilcClientConnection in the client library. Created
1076 also new file lib/silcclient/ops.h. Also added new files
1077 silc/local_command.[ch] and silc/client_ops.[ch].
1079 All these changes were made to make it easier for user interface
1080 designers to create what ever user interface for the SILC client
1083 It is also expected that the server will be moved to lib
1084 directory as well and SILC Server Library will be created;
1085 sometimes in the future.
1087 * Removed Local commands from lib/silccore/silccommand.h as
1088 they are application specific and new client library does not
1089 handle any of those anymore.
1091 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1092 old client implementation in silc/.
1094 * Added support for callback functions in SILC_LOG_* macros.
1095 Application can now set its own callbacks that will be called
1096 instead of using the default functions that will always print
1097 the debug messages to stderr (or stdout). Also, debugging can
1098 now be disabled by setting silc_debug to FALSE and re-enabled by
1099 setting it to TRUE. Note, that logging will still work even
1100 if debugging is disabled.
1102 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1103 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1104 silc_log_reset_debug_callbacks.
1106 * To enable debugging in silc client one must give now -d
1107 option on command line.
1109 * Changed silc_schedule_init to automatically allocate task queues
1110 if they are not allocated before calling it.
1112 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Added GMP 3.1 into math library.
1116 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1119 a channel in SILC network. The packet is used by servers and
1120 routers to notify other routers that user has left a channel.
1121 This little feature was missing until now. Added the feature
1122 to protocol specification as well.
1124 Added functions: silc_server_send_remove_channel_user and
1125 silc_server_remove_channel_user into server.[ch].
1127 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1128 lib/silccore/silcpacket.h. However, they are not implemented
1131 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1133 * Fixed joining to a channel and sending channel messages
1134 between server and router. The channel message sending should
1135 now work inside a cell.
1137 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Fixed the private message sending between server and router.
1140 The private message sending should now work inside a cell.
1142 * Added silc_server_replace_id into server.[ch] to replace
1143 existing ID in the SILC network.
1145 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1146 and silc_idlist_replace_server_id into idlist.[ch] in server.
1148 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * Fixed the server to server connections. Server can again now
1151 connect to router. Router to router connections probably does
1154 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * Added dynamic protocol registering support. Now protocols can
1157 registered and unregistered on the fly. Patch by cras.
1159 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Added lib/contrib directory to hold routines that some platforms
1162 don't have but are needed by SILC.
1164 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1165 into lin/contrib to provide getopt() and getopt_long() for
1166 those who don't have it.
1168 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Added AWAY command to client. When away message is set and
1171 client receives a private message packet the client automatically
1172 replies to the sender with the away message.
1174 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1175 bug seemed to be the cause of recent problems when compiling
1178 * Added version detection support to SKE protocol specification
1179 and added the new changes to the SKE implementation as well.
1180 There were other minor changes in the SKE protocol as well.
1182 Many changes in lib/silcske/silcske.[ch] and in
1183 lib/silcske/payload.[ch].
1185 * Added ^U functionality, clear input line. Patch from cras.
1187 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1189 * Mainly small bugfixes on core library. Fixed some debugging
1190 logging and buffer overflow in silclog.c.
1192 * Updated config.sub and config.guess on the distribution tree.
1194 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Added command lagging support in server. Client may execute
1197 commands now only once in two seconds.
1199 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1201 * Optimized packet reception. MAC computation and checking is now
1202 also more optimized. A lot previously duplicated code is now
1203 used as generic by both client and server.
1205 * Fixed key pair generation in clientutil.c
1207 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * Added into lib/silccore/silcbufutil.[ch] new function;
1210 silc_buffer_realloc.
1212 * Moved generic packet sending/encryption functions to
1213 lib/silccore/silcpacket.[ch] from client and server. Some
1214 rewriting of the functions.
1216 * Moved all generic packet reception/decryption functions to
1217 lib/silccore/silcpacket.[ch] from client and server. The
1218 packet processing is now much cleaner in both client and server.
1219 These were major changes in both client and server.
1221 * Created many common functions in server to do packet sending.
1222 Previously code were duplicated a lot, this has been removed
1225 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1227 * Rewrote major parts of the ID cache system. Don't know
1228 whether it is better now or not but at least the API is more
1231 * Major rewrite on ID cache stuff on client because of the ID
1232 cache API changes. Added idlist.c to client.
1234 * Also major rewrite on ID cache stuff on server as well.
1235 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1236 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1237 in hand, instead they are all put into the ID cache system now.
1238 All server_idlist_* routines uses ID cache now instead of
1239 traversing its own lists (those lists does not exist anymore).
1240 SilcIDList though still exists. Also, SilcXXXEntry's are
1243 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Finally made the SKE implementation compliant to the protocol
1246 specification. All mp integers are now binary encoded as
1247 opposed being HEX encoded.
1249 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1252 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1253 functions: silc_[encode/decode]_pem. Also added function
1254 silc_encode_pem_file to PEM encode with newlines ('\n') for
1257 * SILC public keys are now encoded either PEM or binary. Same
1258 option is for private keys as well. By default private keys
1259 are binary encoded and public keys PEM encoded. Silly HEX
1260 encoding were removed.
1262 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1263 function to create fingerprints.
1265 * Fixed a bug in SHA1; does not change the original data anymore.
1267 * Partly implemented INFO command on client and server side.
1268 Fixed CLEAR command. Changes to SERVER command; show current
1269 server(s) when giving command without arguments. Added
1270 VERSION command to client.
1272 * Added check to server that unregistered connections cannot
1273 execute commands (unless it is specificly allowed).
1275 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Fixed screen refresh.
1279 * Fixed channel joining bug from client. On some circumstances
1280 client tried to join to a channel it had already joined.
1282 * Added public key verification process into client's protocol.c.
1283 The client now verifies the public key from user and saves
1284 it into ~./silc/serverkeys/ directory.
1286 Added into: clientutil.[ch]: silc_client_verify_server_key.
1288 * Changed SKE protocol's silc_ske_initiator_finish function
1289 to accept callback function that verifies the received public
1290 key. Removed old silc_ske_verify_public_key function.
1292 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1295 silc_pkcs_private_key[_data]_set.
1297 * Made the password and public authentication more cleaner in
1298 server's protocol.c.
1300 * Removed historic and obsolete protocol `channel_auth' from
1301 both client and server.
1303 * Removed wrong way of sending command status messages from
1304 server to client in server's command.c. The old way violated
1305 protocol specification.
1307 Changes to silccore/silccommand.[ch]: removed
1308 silc_command_encode_status_payload -> not needed anymore,
1309 changed silc_command_encode_payload_va to accept extra
1310 argument on variable argument list. The argument type must
1311 now be provided to the function. Also, added new function:
1312 silc_command_encode_reply_payload_va which is same as
1313 normal command_encode_payload_va except command status type
1314 is provided as extra argument.
1316 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1318 * Added ~./silc directory handling. The directory includes the
1319 public and private keys for the client.
1321 Added silc_client_check_silc_dir, silc_client_create_identifier
1322 and silc_client_load_keys.
1324 * Implemented SILC protocol compliant public key. Added public
1325 and private key saving to and loading from files.
1327 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1328 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1329 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1330 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1331 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1333 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1334 silc_pkcs_load_[public/private]_key.
1336 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1338 * Added silc_server_get_route (route.[ch]) to get connection
1339 data for the fastest route for given ID.
1341 * Implemented INVITE command on client and server. The command
1342 were re-defined in the SILC Protocol Specification and the
1343 implementation now complies with the specification.
1345 * Implemented PING command on client and server.
1347 * Implemented NAMES command on client and server. The server side
1348 supports currently only normal server not router server yet.
1349 Some changes to NAMES definition in SILC protocol specification.
1351 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Implemented LEAVE command on client and server.
1355 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1356 again. This change was made to the protocol as well. Server
1357 should not violate the protocol specification anymore.
1359 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1361 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1362 was tested. SOCKS4 was not but should work anyway.
