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 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
26 * Added --with-gmp configuration option. If set the GMP
27 is always compiled in the SILC source tree. If not set then
28 it is checked whether the system has the GMP3 installed. If
29 it has then the GMP won't be compiled (the system's headers
30 and library is used), if it doesn't have it then the GMP is
31 compiled in the SILC source tree.
33 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Changed RSA private exponent generation to what PKCS #1
36 suggests. We try to find the smallest possible d by doing
37 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
38 not security fix but optimization.
40 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
42 * Added new config entry [Identity] to fork the server and run
43 it as specific user and group. A patch from Bostik.
45 * Imported Dotconf configuration library into lib/dotconf.
46 This will be used to create the SILC configuration files later.
47 It will appear in the distsribution after this commit.
49 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * A big code auditing weekend happening. Auditing code for
52 obvious mistakes, bugs and errors. Also, removing any code
55 Removed files for being obsolete:
57 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
58 inline in the file lib/silcutil/silcbuffer.h)
60 o lib/silcutil/silcbufutil.c (the header has inline versions)
62 Changed code to fix possible error conditions:
64 o The buffer formatting routines now check that the destination
65 buffer really has enough space to add the data. This applies for
66 both buffer formatting and unformatting
67 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
68 unformatting was changed to accomodate following rules:
69 XXX_*STRING_ALLOC will allocate space for the data into the pointer
70 sent to the function while XXX_*STRING will not allocate or copy
71 the data into the buffer. Instead it sets the pointer from the
72 buffer into the pointer sent as argument (XXX_*STRING used to
73 require that the pointer must be allocated already). This change
74 makes this whole thing a bit more consistent and more optimized
75 (note that the data returned in the unformatting with XXX_*STRING
76 must not be freed now). The routines return now -1 on error.
78 o Tried to find all code that use buffer_format and buffer_unformat
79 and added return value checking to prevent formatting and
80 especially unformatting errors and possible subsequent fatal
83 o Changed ske->x and ske->KEY to mallocated pointers in
84 lib/silcske/silcske.h. Fixed possible data and memory leak.
86 o Added return value checking to all *_parse* functions. Fixed
87 many memory leaks as well.
89 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
90 so that buffer overflows would not happen. All code now also
91 checks the return value as it can fail.
93 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
95 * Added reconnection support to server if the normal server looses
96 its connection to the router (for example if router is rebooted).
97 The server performs normal reconnection strategy implemented
98 to the server. Affected file silcd/server.c.
100 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
102 * Added new packet type SILC_PACKET_SET_MODE that is used to
103 distribute the information about changed modes (for clients,
104 channels and clients channel modes) to all routers in the
105 network. Updated the protocol specification accordingly.
107 Added functions into silcd/packet_send.c and
108 silcd/packet_receive.c: silc_server_send_set_mode,
109 silc_server_set_mode.
111 Added new files silcmode.[ch] into lib/silccore that implements
112 the encoding and decoding of Set Mode Payload. Added new type
113 SilcSetModePayload. Moved the definitions of different modes
114 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
116 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * Oops, a little mistake in server's connection authentication
119 protocol. The protocol is not ended with FAILURE but with
120 SUCCESS if the authentication is Ok. :) Affected file is
123 * Implemented NICK_CHANGE notify handling in server in the file
124 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
125 the local clients on the channel. After the changing nickname
126 in router environment snhould work and the [<unknown>] nickname
127 should appear no more.
129 The silc_server_replace_id function that receives the Replace ID
130 payload now sends the NICK_CHANGE notify type also in the file
131 silcd/packet_receive.c
133 * Changed WHOIS and IDENTIFY command to support the maximum amount
134 of arguments defined in protocol specs (3328 arguments). This
135 fixed a bug that caused problems when there were more than three
138 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
140 * Added extra parameter, command identifier, to the
141 silc_client_send_command so that explicit command identifier
144 Changed that ID list routines uses specific command identifier
145 when sending WHOIS/IDENTIFY requests to the server so that they
146 can be identified when the reply comes back.
148 Affected files lib/silcclient/command.[ch],
149 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
151 * Added `sender' argument to silc_server_packet_send_to_channel
152 to indicaet the sender who originally sent the packet to us
153 that we are now re-sending. Ignored if NULL. Affected file
154 silcd/packet_send.[ch].
156 * Added some server statistics support in silcd/server_internal.h
157 SilcServerStatistics structure and around the server code. Also
158 send some nice statistics information when client is connecting
161 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
163 * Fixed channel ID decoding in server's JOIN command reply in
164 silcd/command_reply.c
166 * Fixed braodcasting of replace ID payload to not to send it if
167 we are standalone server in silcd/packet_receive.c.
169 * Fixed all channel message sending routines to not to send
170 packets to clients that has router set, since they are routed
171 separately in the same function earlier. Affects file
172 silcd/packet_send.c and all channel packet sending functions.
174 * In USERS reply, res_argv[i] are not allocated, the table
175 is allocated. Thus changed that free the table, not its
178 * In server's whois_check and identify_check if the client is
179 locally connected do not send any WHOIS commands - they are not
182 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Fixed some minor bugs in client when sending WHOIS command. The
185 arguments was in wrong order.
187 * Removed statis function add_to_channel from server in
188 silcd/command.c that was previously used with the joining but
191 * Tested USERS command in router environment successfully with two
192 routers, two servers and two clients.
194 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Reorganized the USERS command and command reply in client library
197 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
198 When the command is given by user we register a pending command
199 callback that will reprocess the command after the reply has been
200 received from the server. When reprocessing the packet we then
201 display the information. Thus, the USERS information is displayed
202 now in the command callback instead of in the command reply
203 callback. The processing of the command is same as previously
204 when server has sent the command reply in the JOINing process.
206 * Added to USERS command in silcd/command_reply.c to join the client,
207 we didn't use to know about, to the channel after we've created
208 a client entry for it. Also, for clienet we did know already still
209 check whether it is on the channel or not and add it if not.
211 * Removed silc_server_command_join_notify as the function and its
214 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
216 * Changed the client's pending command handling to the same as the
217 server's pending command handling. It is also now possible to
218 execute command reply functions from other command reply
219 function as the function callbacks for commands and command
220 replies are one and same. The pending commands are not static
221 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
222 in client connection context. Thus, pending commands are server
223 connection specific as it is convenient.
225 Changed the function silc_client_command_pending and
226 silc_client_command_pending_del and added new function
227 silc_client_command_pending_check. Removed the
228 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
231 * Added cmd_ident, current command identifier, to the client
232 connection context in lib/silcclient/client.h to keep track on
233 command identifiers used in command sending. Client's command reply
234 function handling now supports the mandatory command identifiers.
236 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
237 funtions in client to fully support pending command callbacks.
239 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
240 as one of the arguments to the application in the command reply
243 * NOTE: The FORWARDED flag is depracated. It used to be depracated
244 before first releasing SILC but came back. Now it is removed again
245 and should come back nomore. The FORWARDED flag was used only
246 by the JOINing procedure by forwarding the command packet to router.
247 Now, the JOINing procedure has been changed to more generic (due
248 to various router environment issues) and FORWARDED is not needed
249 anymore for anything. The protocol specification is yet to be
252 Now, removed silc_server_packet_forward from server and the flag
253 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
255 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
257 * Renamed NAMES command to USERS command. The NAMES was named that
258 due to historical reasons. Now it is renamed. Also, rewrote
259 parts of the USERS command. The nickname list is not sent anymore
260 by the server. Only Client ID and mode lists are sent in the USERS
261 command. Changed this also to the protocol specification.
263 The client now resolves the names and stuff after it receives
264 the USERS list from the server when joining to the channel.
266 * WHOIS and IDENTIFY commands has been changed to support multiple
267 Client ID's per command. One can now search for multiple users
268 in the network by sending only one WHOIS or IDENTIFY command.
269 Changed the code and the protocol specifications.
271 * Removed silc_server_command_identify_parse and changed that IDENTIFY
272 uses silc_server_command_whois_parse to parse the request. */
274 * If normal server, do not parse the WHOIS and IDENTIFY requests
275 before sending it to the router. Saves some time.
277 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
279 * Fixed JOIN command on client library. Wrong number of arguments
280 used to crash the client.
282 * Added silc_server_channel_has_global function to check whether
283 channel has global users or not.
285 * Added silc_server_channel_has_local function to check whether channel
286 has locally connected clients on the channel.
288 * The silc_server_remove_from_one_channel now checks whether the
289 channel has global users or not after given client was removed from
290 the channel. It also checks whether the channel has local clients
291 on the channel anymore. If it does not have then the channel entry
292 is removed as it is not needed anymore.
294 * The silc_server_notify now checks on JOIN notify whether the joining
295 client is one of locally connected or global. If it is global then
296 the channel has now global users on the channel and that is marked
297 to the channel entry. Also, it now saves the global client to
298 global list who is joining and JOINs it to the channel. This is
299 for normal server, that is.
301 Changed silc_server_send_notify_on_channel,
302 silc_server_packet_relay_to_channel and
303 silc_server_packet_send_to_channel check if we are normal server
304 and client has router set (ie. global client) do not send the
305 message to that client, as it is already routed to our router.
307 * Implemented LEAVE notify type handling in silc_server_notify
310 * Tested LEAVE command in router environment successfully. Tested
311 with two routers, two servers and two clients.
315 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
317 * Implemented SIGNOFF notify type handling in silc_server_notify
320 * silc_server_remove_id now removes the client entry from all channels
321 it has joined and thusly sends SIGNOFF notify type.
323 * Rewrote the NAMES list generation in server by removing two excess
324 loops. The lists are created now inside one loop.
326 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
328 * silc_server_remove_channel_user checks now also global list
329 for channel and client.
331 * silc_server_new_channel_user checks now both local and global
332 list for channel and client. Fixed a bug in client id decoding.
333 Used to decode wrong buffer.
335 * silc_server_channel_message checks now both local and global
336 list for channel entry.
338 * Tested channel joining (hence JOIN) in router environment
339 successfully. Tested with two routers, two servers and two
342 * Tested channel message sending in router environment successfully.
344 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Added silc_server_save_channel_key into server.[ch] to save the
347 received channel key in Channel Key payload processing. It is
348 also used in JOIN command reply handling.
350 Equivalent function silc_client_save_channel_key added into
351 client.[ch] into client library.
353 * Changed JOIN command reply to send information whether the channel
354 was created or not (is existing already) and the channel key
355 payload. Changed protocol specs accordingly.
357 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
358 the request was sent by ID and not by nickname. Crashed on
361 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
364 now correctly save the received data.
366 * silc_server_free_sock_user_data now notifies routers in the
367 network about entities leaving the network.
369 At the same time implemented functions silc_server_remove_id
370 and silc_server_send_remove_id to receive and send REMOVE_ID
371 packets. The packet is used to notify routers in the network
372 about leaving entities. The ID removed will become invalid in
375 * Added function silc_idlist_del_server into server. Removes and
376 free's server entry from ID list.
378 * silc_server_private_message function now checks, if we are router,
379 that the destination ID really is valid ID, naturally.
381 * In router when NEW_ID packet is received (for new client) the
382 hash of the Client ID is saved in the ID Cache but the
383 client->nickname is set to NULL, instead of putting the hash
386 IDENTIFY command now also checks that client->nickname must be
387 valid. If it is not if will request the data from the server who
388 owns the client. Added new function
389 silc_server_command_identify_check.
391 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
392 to set the command to already allocated Command Payload.
394 * Tested private message sending in router environment with two
395 routers, two servers and two clients. Fixed minor bugs and now
398 * Fixed segfault from client's NAMES command. Used to crash if
401 * Forwarded packets must not be routed even if it is not destined
402 to the receiver. Changed server code comply with this.
404 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Added `require_reverse_mapping' boolean value to ServerParams
407 structure. If TRUE (not default) the server will require that
408 the connecting host has fully qualified domain name.
410 If the reverse mapping is not required and hostname could not be
411 found the IP address is used as hostname.
413 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Implemented version string checking to both client and server.
416 The check is incomplete currently due to the abnormal version
417 strings used in development version of SILC.
419 * Changed all command functions in server to use the new
422 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
424 * Changed char *data to unsigned char *data in ID Cache system to
425 support binary data as ID Cache data. Changed code to support
426 binary data in lib/silccore/idcache.c.
428 * Renamed silc_server_packet_relay_command_reply to
429 silc_server_command_reply as it is normal packet receiving
430 function. Rewrote the function to accept command replys for
431 servers and not only for clients.
433 * Mark remote router always as registered server if we are connecting
434 to it. Otherwise, commands sent by the router to us are ignored.
436 * All ID List find routines now returns the ID Cache Entry pointer
437 as well if requested.
439 * WHOIS command works now in router environment, tested with two
440 routers, two servers and two clients.
442 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
443 in router environment (as it is almost equivalent to WHOIS) but
444 hasn't been tested thoroughly. Added new functions:
446 silc_server_command_identify_parse
447 silc_server_command_identify_send_reply
448 silc_server_command_identify_from_client
449 silc_server_command_identify_from_server
451 * Disabled route cache adding because adding two different ID's with
452 same IP replaces the old cache entry thus giving wrong route.
453 The entry->router->connection is always the fastest route anyway
454 so route cache may not be needed. Of course, new routes maybe
455 established after receiving the ID when the entry->router->connection
456 might not be anymore the most optimal.
458 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
460 * Add route cache for received ID for fast routing.
462 * Added silc_server_packet_route to route received packet on router
463 that is not destined to us.
465 * Renamed silc_server_get_route to silc_server_route_get.
467 * Added id_string and id_string_len fields into SilcServer to
468 include encoded ServerID for fast comparing without excess
469 encoding of the ID's.
471 * Cleaned up WHOIS command on server side. Added following static
474 silc_server_command_whois_parse
475 silc_server_command_whois_check
476 silc_server_command_whois_send_reply
477 silc_server_command_whois_from_client
478 silc_server_command_whois_from_server
480 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
481 arguments in command replies. All command functions should be
482 updated to use this macro.
484 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Minor typo fixes on command reply handling on server.
488 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
490 * Added silc_server_command_add_to_channel internal routine to add
491 the client to the channel after router has created the channel and
492 sent command reply to the server.
494 * Added generic silc_server_send_command to send any command from
497 * Use static buffer with ID rendering instead of duplicating data.
499 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
501 * Fixed a channel user mode bug when joining to a channel server gave
502 everybody channel founder rights, oops.
504 * We mark ourselves as the router of the incoming server connection
505 if we are router ourselves. This way we can check in some packet
506 sending functions whether it is locally connected server. For
507 incoming router connections we put NULL.
509 * For router sending packets locally means now always sending the
510 packet cell wide; to local clients and local servers. For normal
511 server sending packet locally means sending it to only local
514 * Fixed the JOIN command to really work in router environment. If the
515 channel is created it is always created by the router. Router is
516 also responsible of making the initial joining to the channel,
517 sending JOIN notify to the sending server and distributing
518 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
519 does not exist server doesn't do anything else but forward the
520 command to the router which performs everything.
522 * Added silc_server_send_channel_key function to send the Channel Key
525 * Added silc_server_create_channel_key to create new channel key. The
526 channel key is now re-generated everytime someone joins or leaves
527 a channel, as protocol dictates. Note: channel->key_len is the
530 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Splitted server.[ch] finally. Created now packet_send.[ch] and
533 packet_receive.[ch] to separate packet sending and receiving
534 routines. The server.[ch] now includes everything else including
535 actual packet processing (writing and reading data) and other
538 Renamed silc_server_private_message_send_internal to
539 silc_server_send_private_message. The routine is still though
540 used only to relay private messages as server does not send
541 private messages itself.
543 Renamed silc_server_new_channel to silc_server_create_new_channel
544 and added new function sicl_server_new_channel that handles the
545 incoming New Channel packet. Added also new sending function
546 silc_server_send_new_channel to send New Channel Payload.
548 * Added new function silc_server_notify to process incoming notify
549 packet to the server/router. Server may then relay the notify
550 to clients if needed.
552 * Added new function silc_server_new_channel_user to process incoming
553 New Channel User packet. Router will redistribute the packet and
554 send JOIN notify to its local clients and locally connected servers
555 if needed. Normal server will send JOIN notify to its local client
556 on same channel when received this packet. Added also corresponding
557 sending function silc_server_send_new_channel_user to sent the
560 * Added boolean route argument to send_notif_to_channel and
561 packet_send_to_channel functions to attempt to route the packet
562 if it is TRUE and send only locally if it is FALSE.
564 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * silc_server_replace_id now broadcasts the received replace ID
567 packet if it is not broadcast packet already. The router must
568 broadcast to inform other routers about changed ID.
570 * Added backpointer to server's router into SilcServer context in
571 silcd/server_internal.h.
573 * Fixed silc_server_packet_broadcast to send correct broadcast
576 * The channel key is now distributed to the local client as soon
577 as it is received from the router (in router environment) so that
578 no other packet may be sent for the channel until client has
581 * silc_server_remove_channel_user now broadcasts the received
582 Remove Channel User packet if it is not broadcast packet already.
583 The router must broadcast to inform other routers about removed
586 * Added users field into SilcPacketContext that is a reference count
587 of the context. One can increase the reference count by calling
588 silc_packet_context_dup which is now changed to just increase the
589 reference count instead of duplicating the data. The reference
590 count is decresed by calling silc_packet_context_free that will
591 free the data after the reference count hits zero.
593 For now on the packet context and everything allocated into it
594 (including the raw packet from network) must be freed by calling
595 the new silc_packet_context_free function. Added also new function
596 silc_packet_context_alloc that must be used now to allocate the
597 context. This also means that if a routine is asynchronous from
598 silc_[client/server]_packet_parse_type the packet context must
599 be duplicated by calling silc_packet_context_dup. Otherwise it
600 gets free'd after silc_[client/server]_packet_parse_type returns.
601 Also, one must remember that if packet is duplicated then its
602 reference count must be decresed by calling the free function as
603 many times as it was duplicated.
605 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
606 from both client and server.
608 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Made joining to a channel working in router environment.
612 * Cleaned up JOIN command on server side and create function
613 silc_server_command_join_channel internal routine to make the
616 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Changed silc_command_pending list to SilcDList. Also, added
619 `ident' field to SilcServerCommandPending structure to identify
620 the reply and to call correct callback.
622 Added silc_server_command_pending_check function to replace the
623 corresnponding macro. The silc_command_pending list is not
626 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
627 to set identifier to previously allocated Command Payload. It
628 is used to set identifier for command when resending Command
631 * Added silc_command_payload_encode_payload to encode Command
632 Payload buffer from SilcCommandPayload structure.
634 * Added silc_argument_payload_encode_payload to encode Argument
635 payload buffer from SilcArgumentPayload structure.
637 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Changed WHOIS command to support router connection on server side.
640 The whois request is always sent to router unless the server is
641 standalone server. After server has received the reply from the
642 router will it send the reply to the client.
644 * Added silc_server_packet_broadcast into silcd/server.[ch] to
645 broadcast received broadcast packet. The function is used only
646 by router. The broadcast packet is always sent to the router's
649 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
650 render given ID to printable string, for log files for example.
652 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Made basic router to router connections working. At least they
655 can now connect to each other but nothing really works the way
656 they are supposed - yet.
658 * Added new initiator token to RouterConnection configuration
659 file in silcd/serverconfig.[ch]. It is used to tell whether we
660 are the initiator to the remote router or whether we'll expect
661 the other end to connect.
663 * Moved registering of listener task to silc_server_init, hence
664 the server starts listenning as soon as it is run, even if it
665 does not have connections to other routers. Let's see how well
668 * Changed default connection retry timeouts for more suitable in
671 * Removed cipher and such arguments from silc_idlist_add_client
672 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
673 Added new function silc_idlist_add_data to add the keys and stuff
676 * Added SilcIDListData structure and added it to SilcClientEntry
677 and SilcServerEntry as their first field in the structure. This
678 way we can explicitly cast the ID entries to the SilcIDListData
679 structure and get common data for the entries. In past, we had
680 to first check what type of connection it is and then cast it to
681 correct ID entry type. Now, we can directly cast the opaque
682 pointer to the SilcIDListData (no matter what ID entry it actually
683 is) and get the data needed.
685 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
687 * Wow, found a bug in scheduler. The scheduler uninitialized itself
688 in some circumstances even if threre were timeout tasks, though not
689 IO tasks, but tasks anyway. Now fixed.
691 * Defined SilcServerConnection structure to hold connection specific
692 stuff about directly connected servers and routers. The definition
693 is currently in silcd/server_internal.h. I thought about having
694 a bit more important role fro this struct but for now it is used
695 only when connecting to other server (or router actually).
697 * Added connecting retry support in server when connecting to
698 router(s). The retry feature implement exponential backoff
699 algorithm. Also, added SilcServerParams structure to hold default
700 parameters for server. For now, it include these retry settings
701 and are hard coded. After server is moded to be as Silc Server
702 Library this structure will be more important.
704 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
706 * Changed client librarys channel->clients table to SilcList and
707 changed code accordingly.
709 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
711 * Changed client's channel table to SilcList and changed code
712 accordingly. Also changed SilcChannelClientEntry to include back-
713 pointer to the channel so that client entry can use that structure
714 as list as well and we have fast cross-reference to the channel.
715 This change dramatically decreased the complexity of channel
716 handling with client entry and vice versa (removed one extra
717 loop when searching for channel entry from many functions).
719 * Changed server->sim from table to SilcDList and changed code
722 * NAMES command can now be used from user interface. It will show
723 the user list on the channel, neatly.
725 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
726 Code now saves realname of the user if it becomes available.
728 * Renamed configure.in to configure.in.pre and made ./prepare
729 script to automatically add correct version string to
730 configure.in which it creates from configure.in.pre.
732 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * NAMES command reply now shows users mode with the nickname when
737 * Moved silc_client_ch[u]mode[_char] functions from
738 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
739 place sucks, they are utility functions and should be in some
742 * Fixed some unsigned int's to unsigned short's. Patch by cras.
744 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
747 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * Added TRQ (efficient deque and list library) into lib/trq. This is
752 a very good list library that is currently used in the SILC. Defined
753 SilcList API over the library because I didn't like the API very
754 much. See lib/trq/silclist.h for the API and examples of how to
755 use the API. Fixed various places in the code to use the new
756 SilcList API. The SilcList is meant for lists that has a structure
757 already defined as a list. It is not suitable to add just some
758 context to the list (in TRQ, the context is the list actually).
760 So, I defined SilcDList that can be used for the purpose where
761 predefined list structure does not exit. This can be used as
762 such list. Now some context just can be added to the SilcDList.
763 Currently this list is not used in the SILC just yet, though there
764 are a lot places where this can replace dynamically allocated
765 tables and I will fix these places, later, to use SilcDList.
766 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
767 and use TRQ internally).
769 Also fixed some annoying warning messages that the original TRQ
770 code generated. Also minor changes to TRQ's Makefile.in.
772 * Added support for querying by Client ID to both WHOIS and
773 IDENTIFY commands into server, as required by the protocol.
775 * Removed method function pointers from SilcBuffer structure. They
776 weren't used to anything and just increased the context size for
777 no good reason. This change also made silc_buffer_alloc and
778 silc_buffer_free functions inline functions.
780 * Disabled command flooding detection support until it's fixed so
781 that it accepts commands in but does not execute them more than once
784 * Added silc_net_localhost(), to return local hostname, into
785 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
786 that must be initialized before calling silc_client_init.
788 * Added new function: silc_server_send_notify_on_channels to send
789 notify messages to all channels client has joined. It is assured
790 that the message is sent only once per client.
792 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
793 lib/silcutil/silcutil.[ch] as silc_format function. The new
794 function is generic and is used by server as well, not only by
795 the logging routines.
797 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
798 the provided version string was not acceptable. Added new function:
799 silc_ske_check_version into lib/silcske/silcske.h. The function
800 must be implemented by the application (client or server) and it
801 does not reside in the SKE library. The function checks the version
802 string remote end sent.
804 * Added back pointers (to opaque context and to SilcSocketConnection)
805 into SilcPacketContext structure into lib/silccore/silcpacket.h.
807 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
808 duplicate packet context structure.
810 * Changed `notify' client operation to send same arguments as client
811 receives from server except for ID's. ID's are mapped to correct
812 ID entry and that is returned. Also, if channel entry is not sent
813 by server but the notify is for channel the channel entry is sent
814 to application (otherwise application doesn't know that it is for
815 channel (library gets it from packet's Destination ID)).
817 * Added silc_client_remove_from_channels into client library to
818 remove a client from all channels it has joined to. Used when
819 received SIGNOFF notify from server. Added also new function
820 silc_client_replace_from_channels to replace old ID entry with
821 new ID entry on all channels. Used when received NICK_CHANGE
824 * Fixed ID Cache list handling in silc_idlist_get_client in
825 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
826 to get (or query) client by ID.
830 * Added connection authentication status message defined by the
831 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
832 support for these into the code in client and server side.
834 * Added generic function silc_client_send_command to send any command
835 with variable argument list. Application should use this function
836 to send commands if the command functions provided by the library
837 does not suite for the application's user interface needs.
839 * Added new `failure' client operation. Application is notified about
840 received failure packet if client is executing a protocol. In this
841 case the protocol's execution has failed.
843 * Added SKE's end notify to send the SKE_SUCCESS notify message that
844 is required by the protocol.
846 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
847 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
850 * Added status flag to SilcSKE object to indicate realtime status
853 * Application receives now exactly same command reply arguments as
854 the library receives from server. However, if ID is received the
855 corresponding ID entry is returned to the application (eg. Client
856 ID is mapped to correct SilcClientEntry entry and that is returned).
857 Changed command_reply client operation due to this change.
859 * Changed all ID's in commands and in command replys as ID Payloads.
860 Change affected both client and server side codes.
862 All ID's sent in SILC network (with execption of ID's in SILC
863 Packet header) are sent in ID Payload to support variable length
866 * Server now notifies nick changes and notifies all clients on
867 the channels about the new nickname (about the new Client ID,
870 * Implemented CMODE command to change channel modes. Supports all
871 channel modes defined by the protocol specs except ban and invite
872 lists. (Also, private channel key mode is supported but support for
873 setting private channel key in client is missing, thus, this mode
874 has no effect on client side (except that server requires that the
875 client uses private channel key and normal channel traffic does not
878 Also, invite mode works per se, but INVITE command does not work
879 yet correctly, so you can set channel as invite only channel but
880 inviting clients to the channel does not work (it is yet to be
881 thought what's the best way to do it).
883 * Added new command SILC_COMMAND_CUMODE to change user mode on the
884 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
885 Implemented CUMODE command to change user's mode on the channel.
886 Supports all modes defined by the protocol specs.
888 * Added NAMES command reply to return users modes on the channel.
890 * Removed unnecessary and slow ciphers from lib/silccrypt.
892 * Set SO_KEEPALIVE option to connection sockets by default.
894 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
896 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
897 redefined the Notify Payload into protocol specs.
899 * Added silc_id_payload_parse_id to get ID directly from raw
902 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
905 accept searching by Client ID as well.
907 * Added support for LEAVE and SIGNOFF notify types in client library.
909 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
910 to parse ID Payload from raw data.
912 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Added flags parameter into silc_ske_assemble_security_properties
915 function in lib/silcske/silcske.[ch].
917 * Changed notify client operation to fit better for notify messages
918 sent by server. The notify payload received from server is now
919 passed to the application (after parsing it to SilcNotifyPayload).
920 It is application's responsibility to retrieve the arguments
921 from the payload and show the message the way it wants. The message
922 sent by server is implementation specific.
924 * Changed public keys to comply with the protocol specification.
925 Old public keys are not supported anymore and are not compatible.
927 * Removed nickname from Channel Payload as the latest draft removed
928 it. The client must resolve the nickname from the NAMES command
929 reply received when it joined the channel.
931 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
933 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Fixed some errors in protocol specification drafts.
937 * Created lib/silccore/silcnotify.c to implement Notify Payload
938 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
939 generic payloads described by protocol specifications. The file
940 includes implementations for ID Payload and Argument Payload.
942 * Changed Command Payload implementation to use the new Argument
943 Payload. Changed command_xxxx_payload to command_payload_xxxx
944 to comply with SILC coding conventions.
946 * Added suppport for Argument Payload handling in Notify Payload
947 implementation as protocol requires it. Added the new support
948 into server and client lib as well.
950 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
952 * Added support for multiple nicknames on same channel. [n] is
953 added locally to the nickname if there are more than one same
954 nicknames on the channel.
956 * Server now sends all nicknames that matched WHOIS request.
957 Client also shows the list received from server.
959 * Added TOPIC command to client side. User can now set and show
960 current topic on channel.
962 * Added MOTD command to client and server. Also, server sends the
963 motd when client connects to the server.
965 * Changed version strings to comply ISO 8601.
967 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Fixed protocol error handling in client library. It should now
970 cope even if the SKE fails for some reason.
972 * Made new protocol specification drafts for submitting to IETF.
974 * Implemented TOPIC command to server in silcd/command.c.
976 * Added two new notify types into lib/silccore/silcnotify.h:
977 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
978 notify nickname change and topic setting/change on a channel.
980 * API change of command_reply operation in client library. The
981 application gets now the status type received from server as well.
983 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * Removed the function just added to lib/silcutil/silcschedule.[ch].
987 * Cras fixed and optimized the packet handling even further and
988 it should work now. Minor change to the prototype of function
989 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
991 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Added new function into lib/silcutil/silcschedule.[ch]:
994 silc_schedule_with_fd to select() a specified fd. The function
995 returns after timeout expires or data arrives or goes. The
996 function is used by packet routines to wait that all data is
997 received from network.
999 * Fixed data reading from network in lib/silccore/silcpacket.c.
1000 The code now assures that all data is read from the fd and then
1001 continues packet processing. This was a bug fix since the code
1002 used to drop some data in some circumstances.
1004 * Added new function into lib/silcclient/client.[ch]:
1005 silc_client_start_key_exchange to start key exchange after
1006 connection has been established to server. The code internally
1007 now uses this funtion but its main purpose was to provide it
1008 for applications that perform their own connecting. After
1009 application has created a connection it merely calls this
1010 function to start the key exchange between client and server.
1011 The library takes care of everything else after that.
1013 Updated also lib/silcclient/README to explain the usage of
1016 * Do not send to application information that connection has
1017 been established. Application gets notified it by connect
1020 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Applied cras's patch to add silc_schedule_one function. The
1023 function runs scheduler once and returns.
1025 * Fixed the scheduler after cras messed it up. The timeout
1026 handling works now as it's supposed to work.
1028 * Added into lib/silccore/ silcnotify.h to include notify
1029 message types support. Changed silc_server_send_notify*
1030 functions, in server.[ch], to support those new notify types.
1031 Added the support for the notify types into client library,
1032 as well. Added new notify client operation into ops.h in
1035 * Changed silc_server_packet_send_to_channel to send normal
1036 packets instead of just channel message packets. The function
1037 is now used to send the notify packets to channels. It is not
1038 used to send channel message packets anymore, as server never
1041 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1042 va_arg()s as it seems to require it nowadays. I guess, if SILC
1043 is compiled with older va_arg() the new code should work anyway.
1045 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Splitted core library. Core library (lib/silccore) includes
1048 now only SILC protocol specific core (and common) components.
1049 Created new utility library (lib/silcutil) that includes more
1050 generic purpose stuff. The stuff for util library was taken
1051 from the old core library. This was minor and easy split.
1053 * Created SILC Client Library (lib/silcclient) that includes
1054 implementation of the SILC client without user interface. This
1055 was major move from silc/ directory. The code has been changed
1056 so that it is transparent towards the user interface. The
1057 silc/ directory includes now the same user interface as before
1058 and it uses the new client library. Read lib/silcclient/README.
1059 Basicly, the client library performs everything else related
1060 to SILC except user interface handling. Also, configuration
1061 files are considered to be part of user interface and library
1062 does not handle them.
1064 This change also changed a lot of structures, function naming etc.
1065 Most important change was that SilcClientWindow object was
1066 renamed to SilcClientConnection in the client library. Created
1067 also new file lib/silcclient/ops.h. Also added new files
1068 silc/local_command.[ch] and silc/client_ops.[ch].
1070 All these changes were made to make it easier for user interface
1071 designers to create what ever user interface for the SILC client
1074 It is also expected that the server will be moved to lib
1075 directory as well and SILC Server Library will be created;
1076 sometimes in the future.
1078 * Removed Local commands from lib/silccore/silccommand.h as
1079 they are application specific and new client library does not
1080 handle any of those anymore.
1082 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1083 old client implementation in silc/.
1085 * Added support for callback functions in SILC_LOG_* macros.
1086 Application can now set its own callbacks that will be called
1087 instead of using the default functions that will always print
1088 the debug messages to stderr (or stdout). Also, debugging can
1089 now be disabled by setting silc_debug to FALSE and re-enabled by
1090 setting it to TRUE. Note, that logging will still work even
1091 if debugging is disabled.
1093 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1094 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1095 silc_log_reset_debug_callbacks.
1097 * To enable debugging in silc client one must give now -d
1098 option on command line.
1100 * Changed silc_schedule_init to automatically allocate task queues
1101 if they are not allocated before calling it.
1103 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Added GMP 3.1 into math library.
1107 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1110 a channel in SILC network. The packet is used by servers and
1111 routers to notify other routers that user has left a channel.
1112 This little feature was missing until now. Added the feature
1113 to protocol specification as well.
1115 Added functions: silc_server_send_remove_channel_user and
1116 silc_server_remove_channel_user into server.[ch].
1118 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1119 lib/silccore/silcpacket.h. However, they are not implemented
1122 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * Fixed joining to a channel and sending channel messages
1125 between server and router. The channel message sending should
1126 now work inside a cell.
1128 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Fixed the private message sending between server and router.
1131 The private message sending should now work inside a cell.
1133 * Added silc_server_replace_id into server.[ch] to replace
1134 existing ID in the SILC network.
1136 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1137 and silc_idlist_replace_server_id into idlist.[ch] in server.
1139 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1141 * Fixed the server to server connections. Server can again now
1142 connect to router. Router to router connections probably does
1145 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * Added dynamic protocol registering support. Now protocols can
1148 registered and unregistered on the fly. Patch by cras.
1150 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1152 * Added lib/contrib directory to hold routines that some platforms
1153 don't have but are needed by SILC.
1155 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1156 into lin/contrib to provide getopt() and getopt_long() for
1157 those who don't have it.
1159 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Added AWAY command to client. When away message is set and
1162 client receives a private message packet the client automatically
1163 replies to the sender with the away message.
1165 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1166 bug seemed to be the cause of recent problems when compiling
1169 * Added version detection support to SKE protocol specification
1170 and added the new changes to the SKE implementation as well.
1171 There were other minor changes in the SKE protocol as well.
1173 Many changes in lib/silcske/silcske.[ch] and in
1174 lib/silcske/payload.[ch].
1176 * Added ^U functionality, clear input line. Patch from cras.
1178 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * Mainly small bugfixes on core library. Fixed some debugging
1181 logging and buffer overflow in silclog.c.
1183 * Updated config.sub and config.guess on the distribution tree.
1185 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Added command lagging support in server. Client may execute
1188 commands now only once in two seconds.
1190 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * Optimized packet reception. MAC computation and checking is now
1193 also more optimized. A lot previously duplicated code is now
1194 used as generic by both client and server.
1196 * Fixed key pair generation in clientutil.c
1198 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1200 * Added into lib/silccore/silcbufutil.[ch] new function;
1201 silc_buffer_realloc.
1203 * Moved generic packet sending/encryption functions to
1204 lib/silccore/silcpacket.[ch] from client and server. Some
1205 rewriting of the functions.
1207 * Moved all generic packet reception/decryption functions to
1208 lib/silccore/silcpacket.[ch] from client and server. The
1209 packet processing is now much cleaner in both client and server.
1210 These were major changes in both client and server.
1212 * Created many common functions in server to do packet sending.
1213 Previously code were duplicated a lot, this has been removed
1216 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Rewrote major parts of the ID cache system. Don't know
1219 whether it is better now or not but at least the API is more
1222 * Major rewrite on ID cache stuff on client because of the ID
1223 cache API changes. Added idlist.c to client.
1225 * Also major rewrite on ID cache stuff on server as well.
1226 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1227 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1228 in hand, instead they are all put into the ID cache system now.
1229 All server_idlist_* routines uses ID cache now instead of
1230 traversing its own lists (those lists does not exist anymore).
1231 SilcIDList though still exists. Also, SilcXXXEntry's are
1234 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Finally made the SKE implementation compliant to the protocol
1237 specification. All mp integers are now binary encoded as
1238 opposed being HEX encoded.
1240 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1243 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1244 functions: silc_[encode/decode]_pem. Also added function
1245 silc_encode_pem_file to PEM encode with newlines ('\n') for
1248 * SILC public keys are now encoded either PEM or binary. Same
1249 option is for private keys as well. By default private keys
1250 are binary encoded and public keys PEM encoded. Silly HEX
1251 encoding were removed.
1253 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1254 function to create fingerprints.
1256 * Fixed a bug in SHA1; does not change the original data anymore.
1258 * Partly implemented INFO command on client and server side.
1259 Fixed CLEAR command. Changes to SERVER command; show current
1260 server(s) when giving command without arguments. Added
1261 VERSION command to client.
1263 * Added check to server that unregistered connections cannot
1264 execute commands (unless it is specificly allowed).
1266 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Fixed screen refresh.
1270 * Fixed channel joining bug from client. On some circumstances
1271 client tried to join to a channel it had already joined.
1273 * Added public key verification process into client's protocol.c.
1274 The client now verifies the public key from user and saves
1275 it into ~./silc/serverkeys/ directory.
1277 Added into: clientutil.[ch]: silc_client_verify_server_key.
1279 * Changed SKE protocol's silc_ske_initiator_finish function
1280 to accept callback function that verifies the received public
1281 key. Removed old silc_ske_verify_public_key function.
1283 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1286 silc_pkcs_private_key[_data]_set.
1288 * Made the password and public authentication more cleaner in
1289 server's protocol.c.
1291 * Removed historic and obsolete protocol `channel_auth' from
1292 both client and server.
1294 * Removed wrong way of sending command status messages from
1295 server to client in server's command.c. The old way violated
1296 protocol specification.
1298 Changes to silccore/silccommand.[ch]: removed
1299 silc_command_encode_status_payload -> not needed anymore,
1300 changed silc_command_encode_payload_va to accept extra
1301 argument on variable argument list. The argument type must
1302 now be provided to the function. Also, added new function:
1303 silc_command_encode_reply_payload_va which is same as
1304 normal command_encode_payload_va except command status type
1305 is provided as extra argument.
1307 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Added ~./silc directory handling. The directory includes the
1310 public and private keys for the client.
1312 Added silc_client_check_silc_dir, silc_client_create_identifier
1313 and silc_client_load_keys.
1315 * Implemented SILC protocol compliant public key. Added public
1316 and private key saving to and loading from files.
1318 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1319 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1320 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1321 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1322 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1324 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1325 silc_pkcs_load_[public/private]_key.
1327 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Added silc_server_get_route (route.[ch]) to get connection
1330 data for the fastest route for given ID.
1332 * Implemented INVITE command on client and server. The command
1333 were re-defined in the SILC Protocol Specification and the
1334 implementation now complies with the specification.
1336 * Implemented PING command on client and server.
1338 * Implemented NAMES command on client and server. The server side
1339 supports currently only normal server not router server yet.
1340 Some changes to NAMES definition in SILC protocol specification.
1342 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Implemented LEAVE command on client and server.
1346 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1347 again. This change was made to the protocol as well. Server
1348 should not violate the protocol specification anymore.
1350 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1352 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1353 was tested. SOCKS4 was not but should work anyway.
