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 * The funtion silc_server_packet_send_local_channel actually did
34 not check whether the client was locally connected or not. It
35 does that now. Fixed a bug related to LEAVE command.
37 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
39 * Added --with-gmp configuration option. If set the GMP
40 is always compiled in the SILC source tree. If not set then
41 it is checked whether the system has the GMP3 installed. If
42 it has then the GMP won't be compiled (the system's headers
43 and library is used), if it doesn't have it then the GMP is
44 compiled in the SILC source tree.
46 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
48 * Changed RSA private exponent generation to what PKCS #1
49 suggests. We try to find the smallest possible d by doing
50 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
51 not security fix but optimization.
53 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Added new config entry [Identity] to fork the server and run
56 it as specific user and group. A patch from Bostik.
58 * Imported Dotconf configuration library into lib/dotconf.
59 This will be used to create the SILC configuration files later.
60 It will appear in the distsribution after this commit.
62 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * A big code auditing weekend happening. Auditing code for
65 obvious mistakes, bugs and errors. Also, removing any code
68 Removed files for being obsolete:
70 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
71 inline in the file lib/silcutil/silcbuffer.h)
73 o lib/silcutil/silcbufutil.c (the header has inline versions)
75 Changed code to fix possible error conditions:
77 o The buffer formatting routines now check that the destination
78 buffer really has enough space to add the data. This applies for
79 both buffer formatting and unformatting
80 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
81 unformatting was changed to accomodate following rules:
82 XXX_*STRING_ALLOC will allocate space for the data into the pointer
83 sent to the function while XXX_*STRING will not allocate or copy
84 the data into the buffer. Instead it sets the pointer from the
85 buffer into the pointer sent as argument (XXX_*STRING used to
86 require that the pointer must be allocated already). This change
87 makes this whole thing a bit more consistent and more optimized
88 (note that the data returned in the unformatting with XXX_*STRING
89 must not be freed now). The routines return now -1 on error.
91 o Tried to find all code that use buffer_format and buffer_unformat
92 and added return value checking to prevent formatting and
93 especially unformatting errors and possible subsequent fatal
96 o Changed ske->x and ske->KEY to mallocated pointers in
97 lib/silcske/silcske.h. Fixed possible data and memory leak.
99 o Added return value checking to all *_parse* functions. Fixed
100 many memory leaks as well.
102 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
103 so that buffer overflows would not happen. All code now also
104 checks the return value as it can fail.
106 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Added reconnection support to server if the normal server looses
109 its connection to the router (for example if router is rebooted).
110 The server performs normal reconnection strategy implemented
111 to the server. Affected file silcd/server.c.
113 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * Added new packet type SILC_PACKET_SET_MODE that is used to
116 distribute the information about changed modes (for clients,
117 channels and clients channel modes) to all routers in the
118 network. Updated the protocol specification accordingly.
120 Added functions into silcd/packet_send.c and
121 silcd/packet_receive.c: silc_server_send_set_mode,
122 silc_server_set_mode.
124 Added new files silcmode.[ch] into lib/silccore that implements
125 the encoding and decoding of Set Mode Payload. Added new type
126 SilcSetModePayload. Moved the definitions of different modes
127 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
129 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
131 * Oops, a little mistake in server's connection authentication
132 protocol. The protocol is not ended with FAILURE but with
133 SUCCESS if the authentication is Ok. :) Affected file is
136 * Implemented NICK_CHANGE notify handling in server in the file
137 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
138 the local clients on the channel. After the changing nickname
139 in router environment snhould work and the [<unknown>] nickname
140 should appear no more.
142 The silc_server_replace_id function that receives the Replace ID
143 payload now sends the NICK_CHANGE notify type also in the file
144 silcd/packet_receive.c
146 * Changed WHOIS and IDENTIFY command to support the maximum amount
147 of arguments defined in protocol specs (3328 arguments). This
148 fixed a bug that caused problems when there were more than three
151 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
153 * Added extra parameter, command identifier, to the
154 silc_client_send_command so that explicit command identifier
157 Changed that ID list routines uses specific command identifier
158 when sending WHOIS/IDENTIFY requests to the server so that they
159 can be identified when the reply comes back.
161 Affected files lib/silcclient/command.[ch],
162 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
164 * Added `sender' argument to silc_server_packet_send_to_channel
165 to indicaet the sender who originally sent the packet to us
166 that we are now re-sending. Ignored if NULL. Affected file
167 silcd/packet_send.[ch].
169 * Added some server statistics support in silcd/server_internal.h
170 SilcServerStatistics structure and around the server code. Also
171 send some nice statistics information when client is connecting
174 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
176 * Fixed channel ID decoding in server's JOIN command reply in
177 silcd/command_reply.c
179 * Fixed braodcasting of replace ID payload to not to send it if
180 we are standalone server in silcd/packet_receive.c.
182 * Fixed all channel message sending routines to not to send
183 packets to clients that has router set, since they are routed
184 separately in the same function earlier. Affects file
185 silcd/packet_send.c and all channel packet sending functions.
187 * In USERS reply, res_argv[i] are not allocated, the table
188 is allocated. Thus changed that free the table, not its
191 * In server's whois_check and identify_check if the client is
192 locally connected do not send any WHOIS commands - they are not
195 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
197 * Fixed some minor bugs in client when sending WHOIS command. The
198 arguments was in wrong order.
200 * Removed statis function add_to_channel from server in
201 silcd/command.c that was previously used with the joining but
204 * Tested USERS command in router environment successfully with two
205 routers, two servers and two clients.
207 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Reorganized the USERS command and command reply in client library
210 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
211 When the command is given by user we register a pending command
212 callback that will reprocess the command after the reply has been
213 received from the server. When reprocessing the packet we then
214 display the information. Thus, the USERS information is displayed
215 now in the command callback instead of in the command reply
216 callback. The processing of the command is same as previously
217 when server has sent the command reply in the JOINing process.
219 * Added to USERS command in silcd/command_reply.c to join the client,
220 we didn't use to know about, to the channel after we've created
221 a client entry for it. Also, for clienet we did know already still
222 check whether it is on the channel or not and add it if not.
224 * Removed silc_server_command_join_notify as the function and its
227 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * Changed the client's pending command handling to the same as the
230 server's pending command handling. It is also now possible to
231 execute command reply functions from other command reply
232 function as the function callbacks for commands and command
233 replies are one and same. The pending commands are not static
234 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
235 in client connection context. Thus, pending commands are server
236 connection specific as it is convenient.
238 Changed the function silc_client_command_pending and
239 silc_client_command_pending_del and added new function
240 silc_client_command_pending_check. Removed the
241 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
244 * Added cmd_ident, current command identifier, to the client
245 connection context in lib/silcclient/client.h to keep track on
246 command identifiers used in command sending. Client's command reply
247 function handling now supports the mandatory command identifiers.
249 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
250 funtions in client to fully support pending command callbacks.
252 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
253 as one of the arguments to the application in the command reply
256 * NOTE: The FORWARDED flag is depracated. It used to be depracated
257 before first releasing SILC but came back. Now it is removed again
258 and should come back nomore. The FORWARDED flag was used only
259 by the JOINing procedure by forwarding the command packet to router.
260 Now, the JOINing procedure has been changed to more generic (due
261 to various router environment issues) and FORWARDED is not needed
262 anymore for anything. The protocol specification is yet to be
265 Now, removed silc_server_packet_forward from server and the flag
266 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
268 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Renamed NAMES command to USERS command. The NAMES was named that
271 due to historical reasons. Now it is renamed. Also, rewrote
272 parts of the USERS command. The nickname list is not sent anymore
273 by the server. Only Client ID and mode lists are sent in the USERS
274 command. Changed this also to the protocol specification.
276 The client now resolves the names and stuff after it receives
277 the USERS list from the server when joining to the channel.
279 * WHOIS and IDENTIFY commands has been changed to support multiple
280 Client ID's per command. One can now search for multiple users
281 in the network by sending only one WHOIS or IDENTIFY command.
282 Changed the code and the protocol specifications.
284 * Removed silc_server_command_identify_parse and changed that IDENTIFY
285 uses silc_server_command_whois_parse to parse the request. */
287 * If normal server, do not parse the WHOIS and IDENTIFY requests
288 before sending it to the router. Saves some time.
290 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
292 * Fixed JOIN command on client library. Wrong number of arguments
293 used to crash the client.
295 * Added silc_server_channel_has_global function to check whether
296 channel has global users or not.
298 * Added silc_server_channel_has_local function to check whether channel
299 has locally connected clients on the channel.
301 * The silc_server_remove_from_one_channel now checks whether the
302 channel has global users or not after given client was removed from
303 the channel. It also checks whether the channel has local clients
304 on the channel anymore. If it does not have then the channel entry
305 is removed as it is not needed anymore.
307 * The silc_server_notify now checks on JOIN notify whether the joining
308 client is one of locally connected or global. If it is global then
309 the channel has now global users on the channel and that is marked
310 to the channel entry. Also, it now saves the global client to
311 global list who is joining and JOINs it to the channel. This is
312 for normal server, that is.
314 Changed silc_server_send_notify_on_channel,
315 silc_server_packet_relay_to_channel and
316 silc_server_packet_send_to_channel check if we are normal server
317 and client has router set (ie. global client) do not send the
318 message to that client, as it is already routed to our router.
320 * Implemented LEAVE notify type handling in silc_server_notify
323 * Tested LEAVE command in router environment successfully. Tested
324 with two routers, two servers and two clients.
328 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
330 * Implemented SIGNOFF notify type handling in silc_server_notify
333 * silc_server_remove_id now removes the client entry from all channels
334 it has joined and thusly sends SIGNOFF notify type.
336 * Rewrote the NAMES list generation in server by removing two excess
337 loops. The lists are created now inside one loop.
339 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * silc_server_remove_channel_user checks now also global list
342 for channel and client.
344 * silc_server_new_channel_user checks now both local and global
345 list for channel and client. Fixed a bug in client id decoding.
346 Used to decode wrong buffer.
348 * silc_server_channel_message checks now both local and global
349 list for channel entry.
351 * Tested channel joining (hence JOIN) in router environment
352 successfully. Tested with two routers, two servers and two
355 * Tested channel message sending in router environment successfully.
357 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
359 * Added silc_server_save_channel_key into server.[ch] to save the
360 received channel key in Channel Key payload processing. It is
361 also used in JOIN command reply handling.
363 Equivalent function silc_client_save_channel_key added into
364 client.[ch] into client library.
366 * Changed JOIN command reply to send information whether the channel
367 was created or not (is existing already) and the channel key
368 payload. Changed protocol specs accordingly.
370 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
371 the request was sent by ID and not by nickname. Crashed on
374 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
377 now correctly save the received data.
379 * silc_server_free_sock_user_data now notifies routers in the
380 network about entities leaving the network.
382 At the same time implemented functions silc_server_remove_id
383 and silc_server_send_remove_id to receive and send REMOVE_ID
384 packets. The packet is used to notify routers in the network
385 about leaving entities. The ID removed will become invalid in
388 * Added function silc_idlist_del_server into server. Removes and
389 free's server entry from ID list.
391 * silc_server_private_message function now checks, if we are router,
392 that the destination ID really is valid ID, naturally.
394 * In router when NEW_ID packet is received (for new client) the
395 hash of the Client ID is saved in the ID Cache but the
396 client->nickname is set to NULL, instead of putting the hash
399 IDENTIFY command now also checks that client->nickname must be
400 valid. If it is not if will request the data from the server who
401 owns the client. Added new function
402 silc_server_command_identify_check.
404 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
405 to set the command to already allocated Command Payload.
407 * Tested private message sending in router environment with two
408 routers, two servers and two clients. Fixed minor bugs and now
411 * Fixed segfault from client's NAMES command. Used to crash if
414 * Forwarded packets must not be routed even if it is not destined
415 to the receiver. Changed server code comply with this.
417 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * Added `require_reverse_mapping' boolean value to ServerParams
420 structure. If TRUE (not default) the server will require that
421 the connecting host has fully qualified domain name.
423 If the reverse mapping is not required and hostname could not be
424 found the IP address is used as hostname.
426 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Implemented version string checking to both client and server.
429 The check is incomplete currently due to the abnormal version
430 strings used in development version of SILC.
432 * Changed all command functions in server to use the new
435 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * Changed char *data to unsigned char *data in ID Cache system to
438 support binary data as ID Cache data. Changed code to support
439 binary data in lib/silccore/idcache.c.
441 * Renamed silc_server_packet_relay_command_reply to
442 silc_server_command_reply as it is normal packet receiving
443 function. Rewrote the function to accept command replys for
444 servers and not only for clients.
446 * Mark remote router always as registered server if we are connecting
447 to it. Otherwise, commands sent by the router to us are ignored.
449 * All ID List find routines now returns the ID Cache Entry pointer
450 as well if requested.
452 * WHOIS command works now in router environment, tested with two
453 routers, two servers and two clients.
455 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
456 in router environment (as it is almost equivalent to WHOIS) but
457 hasn't been tested thoroughly. Added new functions:
459 silc_server_command_identify_parse
460 silc_server_command_identify_send_reply
461 silc_server_command_identify_from_client
462 silc_server_command_identify_from_server
464 * Disabled route cache adding because adding two different ID's with
465 same IP replaces the old cache entry thus giving wrong route.
466 The entry->router->connection is always the fastest route anyway
467 so route cache may not be needed. Of course, new routes maybe
468 established after receiving the ID when the entry->router->connection
469 might not be anymore the most optimal.
471 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
473 * Add route cache for received ID for fast routing.
475 * Added silc_server_packet_route to route received packet on router
476 that is not destined to us.
478 * Renamed silc_server_get_route to silc_server_route_get.
480 * Added id_string and id_string_len fields into SilcServer to
481 include encoded ServerID for fast comparing without excess
482 encoding of the ID's.
484 * Cleaned up WHOIS command on server side. Added following static
487 silc_server_command_whois_parse
488 silc_server_command_whois_check
489 silc_server_command_whois_send_reply
490 silc_server_command_whois_from_client
491 silc_server_command_whois_from_server
493 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
494 arguments in command replies. All command functions should be
495 updated to use this macro.
497 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
499 * Minor typo fixes on command reply handling on server.
501 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * Added silc_server_command_add_to_channel internal routine to add
504 the client to the channel after router has created the channel and
505 sent command reply to the server.
507 * Added generic silc_server_send_command to send any command from
510 * Use static buffer with ID rendering instead of duplicating data.
512 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
514 * Fixed a channel user mode bug when joining to a channel server gave
515 everybody channel founder rights, oops.
517 * We mark ourselves as the router of the incoming server connection
518 if we are router ourselves. This way we can check in some packet
519 sending functions whether it is locally connected server. For
520 incoming router connections we put NULL.
522 * For router sending packets locally means now always sending the
523 packet cell wide; to local clients and local servers. For normal
524 server sending packet locally means sending it to only local
527 * Fixed the JOIN command to really work in router environment. If the
528 channel is created it is always created by the router. Router is
529 also responsible of making the initial joining to the channel,
530 sending JOIN notify to the sending server and distributing
531 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
532 does not exist server doesn't do anything else but forward the
533 command to the router which performs everything.
535 * Added silc_server_send_channel_key function to send the Channel Key
538 * Added silc_server_create_channel_key to create new channel key. The
539 channel key is now re-generated everytime someone joins or leaves
540 a channel, as protocol dictates. Note: channel->key_len is the
543 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
545 * Splitted server.[ch] finally. Created now packet_send.[ch] and
546 packet_receive.[ch] to separate packet sending and receiving
547 routines. The server.[ch] now includes everything else including
548 actual packet processing (writing and reading data) and other
551 Renamed silc_server_private_message_send_internal to
552 silc_server_send_private_message. The routine is still though
553 used only to relay private messages as server does not send
554 private messages itself.
556 Renamed silc_server_new_channel to silc_server_create_new_channel
557 and added new function sicl_server_new_channel that handles the
558 incoming New Channel packet. Added also new sending function
559 silc_server_send_new_channel to send New Channel Payload.
561 * Added new function silc_server_notify to process incoming notify
562 packet to the server/router. Server may then relay the notify
563 to clients if needed.
565 * Added new function silc_server_new_channel_user to process incoming
566 New Channel User packet. Router will redistribute the packet and
567 send JOIN notify to its local clients and locally connected servers
568 if needed. Normal server will send JOIN notify to its local client
569 on same channel when received this packet. Added also corresponding
570 sending function silc_server_send_new_channel_user to sent the
573 * Added boolean route argument to send_notif_to_channel and
574 packet_send_to_channel functions to attempt to route the packet
575 if it is TRUE and send only locally if it is FALSE.
577 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * silc_server_replace_id now broadcasts the received replace ID
580 packet if it is not broadcast packet already. The router must
581 broadcast to inform other routers about changed ID.
583 * Added backpointer to server's router into SilcServer context in
584 silcd/server_internal.h.
586 * Fixed silc_server_packet_broadcast to send correct broadcast
589 * The channel key is now distributed to the local client as soon
590 as it is received from the router (in router environment) so that
591 no other packet may be sent for the channel until client has
594 * silc_server_remove_channel_user now broadcasts the received
595 Remove Channel User packet if it is not broadcast packet already.
596 The router must broadcast to inform other routers about removed
599 * Added users field into SilcPacketContext that is a reference count
600 of the context. One can increase the reference count by calling
601 silc_packet_context_dup which is now changed to just increase the
602 reference count instead of duplicating the data. The reference
603 count is decresed by calling silc_packet_context_free that will
604 free the data after the reference count hits zero.
606 For now on the packet context and everything allocated into it
607 (including the raw packet from network) must be freed by calling
608 the new silc_packet_context_free function. Added also new function
609 silc_packet_context_alloc that must be used now to allocate the
610 context. This also means that if a routine is asynchronous from
611 silc_[client/server]_packet_parse_type the packet context must
612 be duplicated by calling silc_packet_context_dup. Otherwise it
613 gets free'd after silc_[client/server]_packet_parse_type returns.
614 Also, one must remember that if packet is duplicated then its
615 reference count must be decresed by calling the free function as
616 many times as it was duplicated.
618 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
619 from both client and server.
621 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Made joining to a channel working in router environment.
625 * Cleaned up JOIN command on server side and create function
626 silc_server_command_join_channel internal routine to make the
629 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Changed silc_command_pending list to SilcDList. Also, added
632 `ident' field to SilcServerCommandPending structure to identify
633 the reply and to call correct callback.
635 Added silc_server_command_pending_check function to replace the
636 corresnponding macro. The silc_command_pending list is not
639 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
640 to set identifier to previously allocated Command Payload. It
641 is used to set identifier for command when resending Command
644 * Added silc_command_payload_encode_payload to encode Command
645 Payload buffer from SilcCommandPayload structure.
647 * Added silc_argument_payload_encode_payload to encode Argument
648 payload buffer from SilcArgumentPayload structure.
650 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Changed WHOIS command to support router connection on server side.
653 The whois request is always sent to router unless the server is
654 standalone server. After server has received the reply from the
655 router will it send the reply to the client.
657 * Added silc_server_packet_broadcast into silcd/server.[ch] to
658 broadcast received broadcast packet. The function is used only
659 by router. The broadcast packet is always sent to the router's
662 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
663 render given ID to printable string, for log files for example.
665 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
667 * Made basic router to router connections working. At least they
668 can now connect to each other but nothing really works the way
669 they are supposed - yet.
671 * Added new initiator token to RouterConnection configuration
672 file in silcd/serverconfig.[ch]. It is used to tell whether we
673 are the initiator to the remote router or whether we'll expect
674 the other end to connect.
676 * Moved registering of listener task to silc_server_init, hence
677 the server starts listenning as soon as it is run, even if it
678 does not have connections to other routers. Let's see how well
681 * Changed default connection retry timeouts for more suitable in
684 * Removed cipher and such arguments from silc_idlist_add_client
685 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
686 Added new function silc_idlist_add_data to add the keys and stuff
689 * Added SilcIDListData structure and added it to SilcClientEntry
690 and SilcServerEntry as their first field in the structure. This
691 way we can explicitly cast the ID entries to the SilcIDListData
692 structure and get common data for the entries. In past, we had
693 to first check what type of connection it is and then cast it to
694 correct ID entry type. Now, we can directly cast the opaque
695 pointer to the SilcIDListData (no matter what ID entry it actually
696 is) and get the data needed.
698 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * Wow, found a bug in scheduler. The scheduler uninitialized itself
701 in some circumstances even if threre were timeout tasks, though not
702 IO tasks, but tasks anyway. Now fixed.
704 * Defined SilcServerConnection structure to hold connection specific
705 stuff about directly connected servers and routers. The definition
706 is currently in silcd/server_internal.h. I thought about having
707 a bit more important role fro this struct but for now it is used
708 only when connecting to other server (or router actually).
710 * Added connecting retry support in server when connecting to
711 router(s). The retry feature implement exponential backoff
712 algorithm. Also, added SilcServerParams structure to hold default
713 parameters for server. For now, it include these retry settings
714 and are hard coded. After server is moded to be as Silc Server
715 Library this structure will be more important.
717 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
719 * Changed client librarys channel->clients table to SilcList and
720 changed code accordingly.
722 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Changed client's channel table to SilcList and changed code
725 accordingly. Also changed SilcChannelClientEntry to include back-
726 pointer to the channel so that client entry can use that structure
727 as list as well and we have fast cross-reference to the channel.
728 This change dramatically decreased the complexity of channel
729 handling with client entry and vice versa (removed one extra
730 loop when searching for channel entry from many functions).
732 * Changed server->sim from table to SilcDList and changed code
735 * NAMES command can now be used from user interface. It will show
736 the user list on the channel, neatly.
738 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
739 Code now saves realname of the user if it becomes available.
741 * Renamed configure.in to configure.in.pre and made ./prepare
742 script to automatically add correct version string to
743 configure.in which it creates from configure.in.pre.
745 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
747 * NAMES command reply now shows users mode with the nickname when
750 * Moved silc_client_ch[u]mode[_char] functions from
751 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
752 place sucks, they are utility functions and should be in some
755 * Fixed some unsigned int's to unsigned short's. Patch by cras.
757 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
760 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
764 * Added TRQ (efficient deque and list library) into lib/trq. This is
765 a very good list library that is currently used in the SILC. Defined
766 SilcList API over the library because I didn't like the API very
767 much. See lib/trq/silclist.h for the API and examples of how to
768 use the API. Fixed various places in the code to use the new
769 SilcList API. The SilcList is meant for lists that has a structure
770 already defined as a list. It is not suitable to add just some
771 context to the list (in TRQ, the context is the list actually).
773 So, I defined SilcDList that can be used for the purpose where
774 predefined list structure does not exit. This can be used as
775 such list. Now some context just can be added to the SilcDList.
776 Currently this list is not used in the SILC just yet, though there
777 are a lot places where this can replace dynamically allocated
778 tables and I will fix these places, later, to use SilcDList.
779 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
780 and use TRQ internally).
782 Also fixed some annoying warning messages that the original TRQ
783 code generated. Also minor changes to TRQ's Makefile.in.
785 * Added support for querying by Client ID to both WHOIS and
786 IDENTIFY commands into server, as required by the protocol.
788 * Removed method function pointers from SilcBuffer structure. They
789 weren't used to anything and just increased the context size for
790 no good reason. This change also made silc_buffer_alloc and
791 silc_buffer_free functions inline functions.
793 * Disabled command flooding detection support until it's fixed so
794 that it accepts commands in but does not execute them more than once
797 * Added silc_net_localhost(), to return local hostname, into
798 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
799 that must be initialized before calling silc_client_init.
801 * Added new function: silc_server_send_notify_on_channels to send
802 notify messages to all channels client has joined. It is assured
803 that the message is sent only once per client.
805 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
806 lib/silcutil/silcutil.[ch] as silc_format function. The new
807 function is generic and is used by server as well, not only by
808 the logging routines.
810 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
811 the provided version string was not acceptable. Added new function:
812 silc_ske_check_version into lib/silcske/silcske.h. The function
813 must be implemented by the application (client or server) and it
814 does not reside in the SKE library. The function checks the version
815 string remote end sent.
817 * Added back pointers (to opaque context and to SilcSocketConnection)
818 into SilcPacketContext structure into lib/silccore/silcpacket.h.
820 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
821 duplicate packet context structure.
823 * Changed `notify' client operation to send same arguments as client
824 receives from server except for ID's. ID's are mapped to correct
825 ID entry and that is returned. Also, if channel entry is not sent
826 by server but the notify is for channel the channel entry is sent
827 to application (otherwise application doesn't know that it is for
828 channel (library gets it from packet's Destination ID)).
830 * Added silc_client_remove_from_channels into client library to
831 remove a client from all channels it has joined to. Used when
832 received SIGNOFF notify from server. Added also new function
833 silc_client_replace_from_channels to replace old ID entry with
834 new ID entry on all channels. Used when received NICK_CHANGE
837 * Fixed ID Cache list handling in silc_idlist_get_client in
838 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
839 to get (or query) client by ID.
843 * Added connection authentication status message defined by the
844 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
845 support for these into the code in client and server side.
847 * Added generic function silc_client_send_command to send any command
848 with variable argument list. Application should use this function
849 to send commands if the command functions provided by the library
850 does not suite for the application's user interface needs.
852 * Added new `failure' client operation. Application is notified about
853 received failure packet if client is executing a protocol. In this
854 case the protocol's execution has failed.
856 * Added SKE's end notify to send the SKE_SUCCESS notify message that
857 is required by the protocol.
859 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
860 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
863 * Added status flag to SilcSKE object to indicate realtime status
866 * Application receives now exactly same command reply arguments as
867 the library receives from server. However, if ID is received the
868 corresponding ID entry is returned to the application (eg. Client
869 ID is mapped to correct SilcClientEntry entry and that is returned).
870 Changed command_reply client operation due to this change.
872 * Changed all ID's in commands and in command replys as ID Payloads.
873 Change affected both client and server side codes.
875 All ID's sent in SILC network (with execption of ID's in SILC
876 Packet header) are sent in ID Payload to support variable length
879 * Server now notifies nick changes and notifies all clients on
880 the channels about the new nickname (about the new Client ID,
883 * Implemented CMODE command to change channel modes. Supports all
884 channel modes defined by the protocol specs except ban and invite
885 lists. (Also, private channel key mode is supported but support for
886 setting private channel key in client is missing, thus, this mode
887 has no effect on client side (except that server requires that the
888 client uses private channel key and normal channel traffic does not
891 Also, invite mode works per se, but INVITE command does not work
892 yet correctly, so you can set channel as invite only channel but
893 inviting clients to the channel does not work (it is yet to be
894 thought what's the best way to do it).
896 * Added new command SILC_COMMAND_CUMODE to change user mode on the
897 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
898 Implemented CUMODE command to change user's mode on the channel.
899 Supports all modes defined by the protocol specs.
901 * Added NAMES command reply to return users modes on the channel.
903 * Removed unnecessary and slow ciphers from lib/silccrypt.
905 * Set SO_KEEPALIVE option to connection sockets by default.
907 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
909 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
910 redefined the Notify Payload into protocol specs.
912 * Added silc_id_payload_parse_id to get ID directly from raw
915 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
918 accept searching by Client ID as well.
920 * Added support for LEAVE and SIGNOFF notify types in client library.
922 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
923 to parse ID Payload from raw data.
925 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Added flags parameter into silc_ske_assemble_security_properties
928 function in lib/silcske/silcske.[ch].
930 * Changed notify client operation to fit better for notify messages
931 sent by server. The notify payload received from server is now
932 passed to the application (after parsing it to SilcNotifyPayload).
933 It is application's responsibility to retrieve the arguments
934 from the payload and show the message the way it wants. The message
935 sent by server is implementation specific.
937 * Changed public keys to comply with the protocol specification.
938 Old public keys are not supported anymore and are not compatible.
940 * Removed nickname from Channel Payload as the latest draft removed
941 it. The client must resolve the nickname from the NAMES command
942 reply received when it joined the channel.
944 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
946 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Fixed some errors in protocol specification drafts.
950 * Created lib/silccore/silcnotify.c to implement Notify Payload
951 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
952 generic payloads described by protocol specifications. The file
953 includes implementations for ID Payload and Argument Payload.
955 * Changed Command Payload implementation to use the new Argument
956 Payload. Changed command_xxxx_payload to command_payload_xxxx
957 to comply with SILC coding conventions.
959 * Added suppport for Argument Payload handling in Notify Payload
960 implementation as protocol requires it. Added the new support
961 into server and client lib as well.
963 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Added support for multiple nicknames on same channel. [n] is
966 added locally to the nickname if there are more than one same
967 nicknames on the channel.
969 * Server now sends all nicknames that matched WHOIS request.
970 Client also shows the list received from server.
972 * Added TOPIC command to client side. User can now set and show
973 current topic on channel.
975 * Added MOTD command to client and server. Also, server sends the
976 motd when client connects to the server.
978 * Changed version strings to comply ISO 8601.
980 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
982 * Fixed protocol error handling in client library. It should now
983 cope even if the SKE fails for some reason.
985 * Made new protocol specification drafts for submitting to IETF.
987 * Implemented TOPIC command to server in silcd/command.c.
989 * Added two new notify types into lib/silccore/silcnotify.h:
990 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
991 notify nickname change and topic setting/change on a channel.
993 * API change of command_reply operation in client library. The
994 application gets now the status type received from server as well.
996 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1000 * Cras fixed and optimized the packet handling even further and
1001 it should work now. Minor change to the prototype of function
1002 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1004 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Added new function into lib/silcutil/silcschedule.[ch]:
1007 silc_schedule_with_fd to select() a specified fd. The function
1008 returns after timeout expires or data arrives or goes. The
1009 function is used by packet routines to wait that all data is
1010 received from network.
1012 * Fixed data reading from network in lib/silccore/silcpacket.c.
1013 The code now assures that all data is read from the fd and then
1014 continues packet processing. This was a bug fix since the code
1015 used to drop some data in some circumstances.
1017 * Added new function into lib/silcclient/client.[ch]:
1018 silc_client_start_key_exchange to start key exchange after
1019 connection has been established to server. The code internally
1020 now uses this funtion but its main purpose was to provide it
1021 for applications that perform their own connecting. After
1022 application has created a connection it merely calls this
1023 function to start the key exchange between client and server.
1024 The library takes care of everything else after that.
1026 Updated also lib/silcclient/README to explain the usage of
1029 * Do not send to application information that connection has
1030 been established. Application gets notified it by connect
1033 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Applied cras's patch to add silc_schedule_one function. The
1036 function runs scheduler once and returns.
1038 * Fixed the scheduler after cras messed it up. The timeout
1039 handling works now as it's supposed to work.
1041 * Added into lib/silccore/ silcnotify.h to include notify
1042 message types support. Changed silc_server_send_notify*
1043 functions, in server.[ch], to support those new notify types.
1044 Added the support for the notify types into client library,
1045 as well. Added new notify client operation into ops.h in
1048 * Changed silc_server_packet_send_to_channel to send normal
1049 packets instead of just channel message packets. The function
1050 is now used to send the notify packets to channels. It is not
1051 used to send channel message packets anymore, as server never
1054 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1055 va_arg()s as it seems to require it nowadays. I guess, if SILC
1056 is compiled with older va_arg() the new code should work anyway.
1058 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Splitted core library. Core library (lib/silccore) includes
1061 now only SILC protocol specific core (and common) components.
1062 Created new utility library (lib/silcutil) that includes more
1063 generic purpose stuff. The stuff for util library was taken
1064 from the old core library. This was minor and easy split.
1066 * Created SILC Client Library (lib/silcclient) that includes
1067 implementation of the SILC client without user interface. This
1068 was major move from silc/ directory. The code has been changed
1069 so that it is transparent towards the user interface. The
1070 silc/ directory includes now the same user interface as before
1071 and it uses the new client library. Read lib/silcclient/README.
1072 Basicly, the client library performs everything else related
1073 to SILC except user interface handling. Also, configuration
1074 files are considered to be part of user interface and library
1075 does not handle them.
1077 This change also changed a lot of structures, function naming etc.
1078 Most important change was that SilcClientWindow object was
1079 renamed to SilcClientConnection in the client library. Created
1080 also new file lib/silcclient/ops.h. Also added new files
1081 silc/local_command.[ch] and silc/client_ops.[ch].
1083 All these changes were made to make it easier for user interface
1084 designers to create what ever user interface for the SILC client
1087 It is also expected that the server will be moved to lib
1088 directory as well and SILC Server Library will be created;
1089 sometimes in the future.
1091 * Removed Local commands from lib/silccore/silccommand.h as
1092 they are application specific and new client library does not
1093 handle any of those anymore.
1095 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1096 old client implementation in silc/.
1098 * Added support for callback functions in SILC_LOG_* macros.
1099 Application can now set its own callbacks that will be called
1100 instead of using the default functions that will always print
1101 the debug messages to stderr (or stdout). Also, debugging can
1102 now be disabled by setting silc_debug to FALSE and re-enabled by
1103 setting it to TRUE. Note, that logging will still work even
1104 if debugging is disabled.
1106 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1107 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1108 silc_log_reset_debug_callbacks.
1110 * To enable debugging in silc client one must give now -d
1111 option on command line.
1113 * Changed silc_schedule_init to automatically allocate task queues
1114 if they are not allocated before calling it.
1116 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * Added GMP 3.1 into math library.
1120 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1122 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1123 a channel in SILC network. The packet is used by servers and
1124 routers to notify other routers that user has left a channel.
1125 This little feature was missing until now. Added the feature
1126 to protocol specification as well.
1128 Added functions: silc_server_send_remove_channel_user and
1129 silc_server_remove_channel_user into server.[ch].
1131 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1132 lib/silccore/silcpacket.h. However, they are not implemented
1135 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Fixed joining to a channel and sending channel messages
1138 between server and router. The channel message sending should
1139 now work inside a cell.
1141 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Fixed the private message sending between server and router.
1144 The private message sending should now work inside a cell.
1146 * Added silc_server_replace_id into server.[ch] to replace
1147 existing ID in the SILC network.
1149 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1150 and silc_idlist_replace_server_id into idlist.[ch] in server.
1152 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Fixed the server to server connections. Server can again now
1155 connect to router. Router to router connections probably does
1158 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * Added dynamic protocol registering support. Now protocols can
1161 registered and unregistered on the fly. Patch by cras.
1163 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1165 * Added lib/contrib directory to hold routines that some platforms
1166 don't have but are needed by SILC.
1168 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1169 into lin/contrib to provide getopt() and getopt_long() for
1170 those who don't have it.
1172 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * Added AWAY command to client. When away message is set and
1175 client receives a private message packet the client automatically
1176 replies to the sender with the away message.
1178 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1179 bug seemed to be the cause of recent problems when compiling
1182 * Added version detection support to SKE protocol specification
1183 and added the new changes to the SKE implementation as well.
1184 There were other minor changes in the SKE protocol as well.
1186 Many changes in lib/silcske/silcske.[ch] and in
1187 lib/silcske/payload.[ch].
1189 * Added ^U functionality, clear input line. Patch from cras.
1191 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Mainly small bugfixes on core library. Fixed some debugging
1194 logging and buffer overflow in silclog.c.
1196 * Updated config.sub and config.guess on the distribution tree.
1198 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1200 * Added command lagging support in server. Client may execute
1201 commands now only once in two seconds.
1203 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1205 * Optimized packet reception. MAC computation and checking is now
1206 also more optimized. A lot previously duplicated code is now
1207 used as generic by both client and server.
1209 * Fixed key pair generation in clientutil.c
1211 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Added into lib/silccore/silcbufutil.[ch] new function;
1214 silc_buffer_realloc.
1216 * Moved generic packet sending/encryption functions to
1217 lib/silccore/silcpacket.[ch] from client and server. Some
1218 rewriting of the functions.
1220 * Moved all generic packet reception/decryption functions to
1221 lib/silccore/silcpacket.[ch] from client and server. The
1222 packet processing is now much cleaner in both client and server.
1223 These were major changes in both client and server.
1225 * Created many common functions in server to do packet sending.
1226 Previously code were duplicated a lot, this has been removed
1229 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Rewrote major parts of the ID cache system. Don't know
1232 whether it is better now or not but at least the API is more
1235 * Major rewrite on ID cache stuff on client because of the ID
1236 cache API changes. Added idlist.c to client.
1238 * Also major rewrite on ID cache stuff on server as well.
1239 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1240 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1241 in hand, instead they are all put into the ID cache system now.
1242 All server_idlist_* routines uses ID cache now instead of
1243 traversing its own lists (those lists does not exist anymore).
1244 SilcIDList though still exists. Also, SilcXXXEntry's are
1247 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1249 * Finally made the SKE implementation compliant to the protocol
1250 specification. All mp integers are now binary encoded as
1251 opposed being HEX encoded.
1253 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1256 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1257 functions: silc_[encode/decode]_pem. Also added function
1258 silc_encode_pem_file to PEM encode with newlines ('\n') for
1261 * SILC public keys are now encoded either PEM or binary. Same
1262 option is for private keys as well. By default private keys
1263 are binary encoded and public keys PEM encoded. Silly HEX
1264 encoding were removed.
1266 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1267 function to create fingerprints.
1269 * Fixed a bug in SHA1; does not change the original data anymore.
1271 * Partly implemented INFO command on client and server side.
1272 Fixed CLEAR command. Changes to SERVER command; show current
1273 server(s) when giving command without arguments. Added
1274 VERSION command to client.
1276 * Added check to server that unregistered connections cannot
1277 execute commands (unless it is specificly allowed).
1279 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Fixed screen refresh.
1283 * Fixed channel joining bug from client. On some circumstances
1284 client tried to join to a channel it had already joined.
1286 * Added public key verification process into client's protocol.c.
1287 The client now verifies the public key from user and saves
1288 it into ~./silc/serverkeys/ directory.
1290 Added into: clientutil.[ch]: silc_client_verify_server_key.
1292 * Changed SKE protocol's silc_ske_initiator_finish function
1293 to accept callback function that verifies the received public
1294 key. Removed old silc_ske_verify_public_key function.
1296 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1299 silc_pkcs_private_key[_data]_set.
1301 * Made the password and public authentication more cleaner in
1302 server's protocol.c.
1304 * Removed historic and obsolete protocol `channel_auth' from
1305 both client and server.
1307 * Removed wrong way of sending command status messages from
1308 server to client in server's command.c. The old way violated
1309 protocol specification.
1311 Changes to silccore/silccommand.[ch]: removed
1312 silc_command_encode_status_payload -> not needed anymore,
1313 changed silc_command_encode_payload_va to accept extra
1314 argument on variable argument list. The argument type must
1315 now be provided to the function. Also, added new function:
1316 silc_command_encode_reply_payload_va which is same as
1317 normal command_encode_payload_va except command status type
1318 is provided as extra argument.
1320 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1322 * Added ~./silc directory handling. The directory includes the
1323 public and private keys for the client.
1325 Added silc_client_check_silc_dir, silc_client_create_identifier
1326 and silc_client_load_keys.
1328 * Implemented SILC protocol compliant public key. Added public
1329 and private key saving to and loading from files.
1331 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1332 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1333 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1334 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1335 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1337 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1338 silc_pkcs_load_[public/private]_key.
1340 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Added silc_server_get_route (route.[ch]) to get connection
1343 data for the fastest route for given ID.
1345 * Implemented INVITE command on client and server. The command
1346 were re-defined in the SILC Protocol Specification and the
1347 implementation now complies with the specification.
1349 * Implemented PING command on client and server.
1351 * Implemented NAMES command on client and server. The server side
1352 supports currently only normal server not router server yet.
1353 Some changes to NAMES definition in SILC protocol specification.
1355 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1357 * Implemented LEAVE command on client and server.
1359 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1360 again. This change was made to the protocol as well. Server
1361 should not violate the protocol specification anymore.
1363 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1366 was tested. SOCKS4 was not but should work anyway.
