1 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
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 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Added --with-gmp configuration option. If set the GMP
17 is always compiled in the SILC source tree. If not set then
18 it is checked whether the system has the GMP3 installed. If
19 it has then the GMP won't be compiled (the system's headers
20 and library is used), if it doesn't have it then the GMP is
21 compiled in the SILC source tree.
23 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Changed RSA private exponent generation to what PKCS #1
26 suggests. We try to find the smallest possible d by doing
27 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
28 not security fix but optimization.
30 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
32 * Added new config entry [Identity] to fork the server and run
33 it as specific user and group. A patch from Bostik.
35 * Imported Dotconf configuration library into lib/dotconf.
36 This will be used to create the SILC configuration files later.
37 It will appear in the distsribution after this commit.
39 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
41 * A big code auditing weekend happening. Auditing code for
42 obvious mistakes, bugs and errors. Also, removing any code
45 Removed files for being obsolete:
47 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
48 inline in the file lib/silcutil/silcbuffer.h)
50 o lib/silcutil/silcbufutil.c (the header has inline versions)
52 Changed code to fix possible error conditions:
54 o The buffer formatting routines now check that the destination
55 buffer really has enough space to add the data. This applies for
56 both buffer formatting and unformatting
57 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
58 unformatting was changed to accomodate following rules:
59 XXX_*STRING_ALLOC will allocate space for the data into the pointer
60 sent to the function while XXX_*STRING will not allocate or copy
61 the data into the buffer. Instead it sets the pointer from the
62 buffer into the pointer sent as argument (XXX_*STRING used to
63 require that the pointer must be allocated already). This change
64 makes this whole thing a bit more consistent and more optimized
65 (note that the data returned in the unformatting with XXX_*STRING
66 must not be freed now). The routines return now -1 on error.
68 o Tried to find all code that use buffer_format and buffer_unformat
69 and added return value checking to prevent formatting and
70 especially unformatting errors and possible subsequent fatal
73 o Changed ske->x and ske->KEY to mallocated pointers in
74 lib/silcske/silcske.h. Fixed possible data and memory leak.
76 o Added return value checking to all *_parse* functions. Fixed
77 many memory leaks as well.
79 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
80 so that buffer overflows would not happen. All code now also
81 checks the return value as it can fail.
83 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Added reconnection support to server if the normal server looses
86 its connection to the router (for example if router is rebooted).
87 The server performs normal reconnection strategy implemented
88 to the server. Affected file silcd/server.c.
90 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
92 * Added new packet type SILC_PACKET_SET_MODE that is used to
93 distribute the information about changed modes (for clients,
94 channels and clients channel modes) to all routers in the
95 network. Updated the protocol specification accordingly.
97 Added functions into silcd/packet_send.c and
98 silcd/packet_receive.c: silc_server_send_set_mode,
101 Added new files silcmode.[ch] into lib/silccore that implements
102 the encoding and decoding of Set Mode Payload. Added new type
103 SilcSetModePayload. Moved the definitions of different modes
104 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
106 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Oops, a little mistake in server's connection authentication
109 protocol. The protocol is not ended with FAILURE but with
110 SUCCESS if the authentication is Ok. :) Affected file is
113 * Implemented NICK_CHANGE notify handling in server in the file
114 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
115 the local clients on the channel. After the changing nickname
116 in router environment snhould work and the [<unknown>] nickname
117 should appear no more.
119 The silc_server_replace_id function that receives the Replace ID
120 payload now sends the NICK_CHANGE notify type also in the file
121 silcd/packet_receive.c
123 * Changed WHOIS and IDENTIFY command to support the maximum amount
124 of arguments defined in protocol specs (3328 arguments). This
125 fixed a bug that caused problems when there were more than three
128 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Added extra parameter, command identifier, to the
131 silc_client_send_command so that explicit command identifier
134 Changed that ID list routines uses specific command identifier
135 when sending WHOIS/IDENTIFY requests to the server so that they
136 can be identified when the reply comes back.
138 Affected files lib/silcclient/command.[ch],
139 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
141 * Added `sender' argument to silc_server_packet_send_to_channel
142 to indicaet the sender who originally sent the packet to us
143 that we are now re-sending. Ignored if NULL. Affected file
144 silcd/packet_send.[ch].
146 * Added some server statistics support in silcd/server_internal.h
147 SilcServerStatistics structure and around the server code. Also
148 send some nice statistics information when client is connecting
151 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
153 * Fixed channel ID decoding in server's JOIN command reply in
154 silcd/command_reply.c
156 * Fixed braodcasting of replace ID payload to not to send it if
157 we are standalone server in silcd/packet_receive.c.
159 * Fixed all channel message sending routines to not to send
160 packets to clients that has router set, since they are routed
161 separately in the same function earlier. Affects file
162 silcd/packet_send.c and all channel packet sending functions.
164 * In USERS reply, res_argv[i] are not allocated, the table
165 is allocated. Thus changed that free the table, not its
168 * In server's whois_check and identify_check if the client is
169 locally connected do not send any WHOIS commands - they are not
172 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
174 * Fixed some minor bugs in client when sending WHOIS command. The
175 arguments was in wrong order.
177 * Removed statis function add_to_channel from server in
178 silcd/command.c that was previously used with the joining but
181 * Tested USERS command in router environment successfully with two
182 routers, two servers and two clients.
184 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Reorganized the USERS command and command reply in client library
187 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
188 When the command is given by user we register a pending command
189 callback that will reprocess the command after the reply has been
190 received from the server. When reprocessing the packet we then
191 display the information. Thus, the USERS information is displayed
192 now in the command callback instead of in the command reply
193 callback. The processing of the command is same as previously
194 when server has sent the command reply in the JOINing process.
196 * Added to USERS command in silcd/command_reply.c to join the client,
197 we didn't use to know about, to the channel after we've created
198 a client entry for it. Also, for clienet we did know already still
199 check whether it is on the channel or not and add it if not.
201 * Removed silc_server_command_join_notify as the function and its
204 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * Changed the client's pending command handling to the same as the
207 server's pending command handling. It is also now possible to
208 execute command reply functions from other command reply
209 function as the function callbacks for commands and command
210 replies are one and same. The pending commands are not static
211 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
212 in client connection context. Thus, pending commands are server
213 connection specific as it is convenient.
215 Changed the function silc_client_command_pending and
216 silc_client_command_pending_del and added new function
217 silc_client_command_pending_check. Removed the
218 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
221 * Added cmd_ident, current command identifier, to the client
222 connection context in lib/silcclient/client.h to keep track on
223 command identifiers used in command sending. Client's command reply
224 function handling now supports the mandatory command identifiers.
226 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
227 funtions in client to fully support pending command callbacks.
229 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
230 as one of the arguments to the application in the command reply
233 * NOTE: The FORWARDED flag is depracated. It used to be depracated
234 before first releasing SILC but came back. Now it is removed again
235 and should come back nomore. The FORWARDED flag was used only
236 by the JOINing procedure by forwarding the command packet to router.
237 Now, the JOINing procedure has been changed to more generic (due
238 to various router environment issues) and FORWARDED is not needed
239 anymore for anything. The protocol specification is yet to be
242 Now, removed silc_server_packet_forward from server and the flag
243 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
245 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Renamed NAMES command to USERS command. The NAMES was named that
248 due to historical reasons. Now it is renamed. Also, rewrote
249 parts of the USERS command. The nickname list is not sent anymore
250 by the server. Only Client ID and mode lists are sent in the USERS
251 command. Changed this also to the protocol specification.
253 The client now resolves the names and stuff after it receives
254 the USERS list from the server when joining to the channel.
256 * WHOIS and IDENTIFY commands has been changed to support multiple
257 Client ID's per command. One can now search for multiple users
258 in the network by sending only one WHOIS or IDENTIFY command.
259 Changed the code and the protocol specifications.
261 * Removed silc_server_command_identify_parse and changed that IDENTIFY
262 uses silc_server_command_whois_parse to parse the request. */
264 * If normal server, do not parse the WHOIS and IDENTIFY requests
265 before sending it to the router. Saves some time.
267 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
269 * Fixed JOIN command on client library. Wrong number of arguments
270 used to crash the client.
272 * Added silc_server_channel_has_global function to check whether
273 channel has global users or not.
275 * Added silc_server_channel_has_local function to check whether channel
276 has locally connected clients on the channel.
278 * The silc_server_remove_from_one_channel now checks whether the
279 channel has global users or not after given client was removed from
280 the channel. It also checks whether the channel has local clients
281 on the channel anymore. If it does not have then the channel entry
282 is removed as it is not needed anymore.
284 * The silc_server_notify now checks on JOIN notify whether the joining
285 client is one of locally connected or global. If it is global then
286 the channel has now global users on the channel and that is marked
287 to the channel entry. Also, it now saves the global client to
288 global list who is joining and JOINs it to the channel. This is
289 for normal server, that is.
291 Changed silc_server_send_notify_on_channel,
292 silc_server_packet_relay_to_channel and
293 silc_server_packet_send_to_channel check if we are normal server
294 and client has router set (ie. global client) do not send the
295 message to that client, as it is already routed to our router.
297 * Implemented LEAVE notify type handling in silc_server_notify
300 * Tested LEAVE command in router environment successfully. Tested
301 with two routers, two servers and two clients.
305 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
307 * Implemented SIGNOFF notify type handling in silc_server_notify
310 * silc_server_remove_id now removes the client entry from all channels
311 it has joined and thusly sends SIGNOFF notify type.
313 * Rewrote the NAMES list generation in server by removing two excess
314 loops. The lists are created now inside one loop.
316 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * silc_server_remove_channel_user checks now also global list
319 for channel and client.
321 * silc_server_new_channel_user checks now both local and global
322 list for channel and client. Fixed a bug in client id decoding.
323 Used to decode wrong buffer.
325 * silc_server_channel_message checks now both local and global
326 list for channel entry.
328 * Tested channel joining (hence JOIN) in router environment
329 successfully. Tested with two routers, two servers and two
332 * Tested channel message sending in router environment successfully.
334 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Added silc_server_save_channel_key into server.[ch] to save the
337 received channel key in Channel Key payload processing. It is
338 also used in JOIN command reply handling.
340 Equivalent function silc_client_save_channel_key added into
341 client.[ch] into client library.
343 * Changed JOIN command reply to send information whether the channel
344 was created or not (is existing already) and the channel key
345 payload. Changed protocol specs accordingly.
347 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
348 the request was sent by ID and not by nickname. Crashed on
351 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
354 now correctly save the received data.
356 * silc_server_free_sock_user_data now notifies routers in the
357 network about entities leaving the network.
359 At the same time implemented functions silc_server_remove_id
360 and silc_server_send_remove_id to receive and send REMOVE_ID
361 packets. The packet is used to notify routers in the network
362 about leaving entities. The ID removed will become invalid in
365 * Added function silc_idlist_del_server into server. Removes and
366 free's server entry from ID list.
368 * silc_server_private_message function now checks, if we are router,
369 that the destination ID really is valid ID, naturally.
371 * In router when NEW_ID packet is received (for new client) the
372 hash of the Client ID is saved in the ID Cache but the
373 client->nickname is set to NULL, instead of putting the hash
376 IDENTIFY command now also checks that client->nickname must be
377 valid. If it is not if will request the data from the server who
378 owns the client. Added new function
379 silc_server_command_identify_check.
381 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
382 to set the command to already allocated Command Payload.
384 * Tested private message sending in router environment with two
385 routers, two servers and two clients. Fixed minor bugs and now
388 * Fixed segfault from client's NAMES command. Used to crash if
391 * Forwarded packets must not be routed even if it is not destined
392 to the receiver. Changed server code comply with this.
394 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
396 * Added `require_reverse_mapping' boolean value to ServerParams
397 structure. If TRUE (not default) the server will require that
398 the connecting host has fully qualified domain name.
400 If the reverse mapping is not required and hostname could not be
401 found the IP address is used as hostname.
403 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Implemented version string checking to both client and server.
406 The check is incomplete currently due to the abnormal version
407 strings used in development version of SILC.
409 * Changed all command functions in server to use the new
412 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
414 * Changed char *data to unsigned char *data in ID Cache system to
415 support binary data as ID Cache data. Changed code to support
416 binary data in lib/silccore/idcache.c.
418 * Renamed silc_server_packet_relay_command_reply to
419 silc_server_command_reply as it is normal packet receiving
420 function. Rewrote the function to accept command replys for
421 servers and not only for clients.
423 * Mark remote router always as registered server if we are connecting
424 to it. Otherwise, commands sent by the router to us are ignored.
426 * All ID List find routines now returns the ID Cache Entry pointer
427 as well if requested.
429 * WHOIS command works now in router environment, tested with two
430 routers, two servers and two clients.
432 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
433 in router environment (as it is almost equivalent to WHOIS) but
434 hasn't been tested thoroughly. Added new functions:
436 silc_server_command_identify_parse
437 silc_server_command_identify_send_reply
438 silc_server_command_identify_from_client
439 silc_server_command_identify_from_server
441 * Disabled route cache adding because adding two different ID's with
442 same IP replaces the old cache entry thus giving wrong route.
443 The entry->router->connection is always the fastest route anyway
444 so route cache may not be needed. Of course, new routes maybe
445 established after receiving the ID when the entry->router->connection
446 might not be anymore the most optimal.
448 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Add route cache for received ID for fast routing.
452 * Added silc_server_packet_route to route received packet on router
453 that is not destined to us.
455 * Renamed silc_server_get_route to silc_server_route_get.
457 * Added id_string and id_string_len fields into SilcServer to
458 include encoded ServerID for fast comparing without excess
459 encoding of the ID's.
461 * Cleaned up WHOIS command on server side. Added following static
464 silc_server_command_whois_parse
465 silc_server_command_whois_check
466 silc_server_command_whois_send_reply
467 silc_server_command_whois_from_client
468 silc_server_command_whois_from_server
470 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
471 arguments in command replies. All command functions should be
472 updated to use this macro.
474 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Minor typo fixes on command reply handling on server.
478 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
480 * Added silc_server_command_add_to_channel internal routine to add
481 the client to the channel after router has created the channel and
482 sent command reply to the server.
484 * Added generic silc_server_send_command to send any command from
487 * Use static buffer with ID rendering instead of duplicating data.
489 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
491 * Fixed a channel user mode bug when joining to a channel server gave
492 everybody channel founder rights, oops.
494 * We mark ourselves as the router of the incoming server connection
495 if we are router ourselves. This way we can check in some packet
496 sending functions whether it is locally connected server. For
497 incoming router connections we put NULL.
499 * For router sending packets locally means now always sending the
500 packet cell wide; to local clients and local servers. For normal
501 server sending packet locally means sending it to only local
504 * Fixed the JOIN command to really work in router environment. If the
505 channel is created it is always created by the router. Router is
506 also responsible of making the initial joining to the channel,
507 sending JOIN notify to the sending server and distributing
508 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
509 does not exist server doesn't do anything else but forward the
510 command to the router which performs everything.
512 * Added silc_server_send_channel_key function to send the Channel Key
515 * Added silc_server_create_channel_key to create new channel key. The
516 channel key is now re-generated everytime someone joins or leaves
517 a channel, as protocol dictates. Note: channel->key_len is the
520 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
522 * Splitted server.[ch] finally. Created now packet_send.[ch] and
523 packet_receive.[ch] to separate packet sending and receiving
524 routines. The server.[ch] now includes everything else including
525 actual packet processing (writing and reading data) and other
528 Renamed silc_server_private_message_send_internal to
529 silc_server_send_private_message. The routine is still though
530 used only to relay private messages as server does not send
531 private messages itself.
533 Renamed silc_server_new_channel to silc_server_create_new_channel
534 and added new function sicl_server_new_channel that handles the
535 incoming New Channel packet. Added also new sending function
536 silc_server_send_new_channel to send New Channel Payload.
538 * Added new function silc_server_notify to process incoming notify
539 packet to the server/router. Server may then relay the notify
540 to clients if needed.
542 * Added new function silc_server_new_channel_user to process incoming
543 New Channel User packet. Router will redistribute the packet and
544 send JOIN notify to its local clients and locally connected servers
545 if needed. Normal server will send JOIN notify to its local client
546 on same channel when received this packet. Added also corresponding
547 sending function silc_server_send_new_channel_user to sent the
550 * Added boolean route argument to send_notif_to_channel and
551 packet_send_to_channel functions to attempt to route the packet
552 if it is TRUE and send only locally if it is FALSE.
554 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * silc_server_replace_id now broadcasts the received replace ID
557 packet if it is not broadcast packet already. The router must
558 broadcast to inform other routers about changed ID.
560 * Added backpointer to server's router into SilcServer context in
561 silcd/server_internal.h.
563 * Fixed silc_server_packet_broadcast to send correct broadcast
566 * The channel key is now distributed to the local client as soon
567 as it is received from the router (in router environment) so that
568 no other packet may be sent for the channel until client has
571 * silc_server_remove_channel_user now broadcasts the received
572 Remove Channel User packet if it is not broadcast packet already.
573 The router must broadcast to inform other routers about removed
576 * Added users field into SilcPacketContext that is a reference count
577 of the context. One can increase the reference count by calling
578 silc_packet_context_dup which is now changed to just increase the
579 reference count instead of duplicating the data. The reference
580 count is decresed by calling silc_packet_context_free that will
581 free the data after the reference count hits zero.
583 For now on the packet context and everything allocated into it
584 (including the raw packet from network) must be freed by calling
585 the new silc_packet_context_free function. Added also new function
586 silc_packet_context_alloc that must be used now to allocate the
587 context. This also means that if a routine is asynchronous from
588 silc_[client/server]_packet_parse_type the packet context must
589 be duplicated by calling silc_packet_context_dup. Otherwise it
590 gets free'd after silc_[client/server]_packet_parse_type returns.
591 Also, one must remember that if packet is duplicated then its
592 reference count must be decresed by calling the free function as
593 many times as it was duplicated.
595 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
596 from both client and server.
598 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Made joining to a channel working in router environment.
602 * Cleaned up JOIN command on server side and create function
603 silc_server_command_join_channel internal routine to make the
606 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * Changed silc_command_pending list to SilcDList. Also, added
609 `ident' field to SilcServerCommandPending structure to identify
610 the reply and to call correct callback.
612 Added silc_server_command_pending_check function to replace the
613 corresnponding macro. The silc_command_pending list is not
616 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
617 to set identifier to previously allocated Command Payload. It
618 is used to set identifier for command when resending Command
621 * Added silc_command_payload_encode_payload to encode Command
622 Payload buffer from SilcCommandPayload structure.
624 * Added silc_argument_payload_encode_payload to encode Argument
625 payload buffer from SilcArgumentPayload structure.
627 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
629 * Changed WHOIS command to support router connection on server side.
630 The whois request is always sent to router unless the server is
631 standalone server. After server has received the reply from the
632 router will it send the reply to the client.
634 * Added silc_server_packet_broadcast into silcd/server.[ch] to
635 broadcast received broadcast packet. The function is used only
636 by router. The broadcast packet is always sent to the router's
639 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
640 render given ID to printable string, for log files for example.
642 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Made basic router to router connections working. At least they
645 can now connect to each other but nothing really works the way
646 they are supposed - yet.
648 * Added new initiator token to RouterConnection configuration
649 file in silcd/serverconfig.[ch]. It is used to tell whether we
650 are the initiator to the remote router or whether we'll expect
651 the other end to connect.
653 * Moved registering of listener task to silc_server_init, hence
654 the server starts listenning as soon as it is run, even if it
655 does not have connections to other routers. Let's see how well
658 * Changed default connection retry timeouts for more suitable in
661 * Removed cipher and such arguments from silc_idlist_add_client
662 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
663 Added new function silc_idlist_add_data to add the keys and stuff
666 * Added SilcIDListData structure and added it to SilcClientEntry
667 and SilcServerEntry as their first field in the structure. This
668 way we can explicitly cast the ID entries to the SilcIDListData
669 structure and get common data for the entries. In past, we had
670 to first check what type of connection it is and then cast it to
671 correct ID entry type. Now, we can directly cast the opaque
672 pointer to the SilcIDListData (no matter what ID entry it actually
673 is) and get the data needed.
675 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
677 * Wow, found a bug in scheduler. The scheduler uninitialized itself
678 in some circumstances even if threre were timeout tasks, though not
679 IO tasks, but tasks anyway. Now fixed.
681 * Defined SilcServerConnection structure to hold connection specific
682 stuff about directly connected servers and routers. The definition
683 is currently in silcd/server_internal.h. I thought about having
684 a bit more important role fro this struct but for now it is used
685 only when connecting to other server (or router actually).
687 * Added connecting retry support in server when connecting to
688 router(s). The retry feature implement exponential backoff
689 algorithm. Also, added SilcServerParams structure to hold default
690 parameters for server. For now, it include these retry settings
691 and are hard coded. After server is moded to be as Silc Server
692 Library this structure will be more important.
694 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Changed client librarys channel->clients table to SilcList and
697 changed code accordingly.
699 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Changed client's channel table to SilcList and changed code
702 accordingly. Also changed SilcChannelClientEntry to include back-
703 pointer to the channel so that client entry can use that structure
704 as list as well and we have fast cross-reference to the channel.
705 This change dramatically decreased the complexity of channel
706 handling with client entry and vice versa (removed one extra
707 loop when searching for channel entry from many functions).
709 * Changed server->sim from table to SilcDList and changed code
712 * NAMES command can now be used from user interface. It will show
713 the user list on the channel, neatly.
715 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
716 Code now saves realname of the user if it becomes available.
718 * Renamed configure.in to configure.in.pre and made ./prepare
719 script to automatically add correct version string to
720 configure.in which it creates from configure.in.pre.
722 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * NAMES command reply now shows users mode with the nickname when
727 * Moved silc_client_ch[u]mode[_char] functions from
728 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
729 place sucks, they are utility functions and should be in some
732 * Fixed some unsigned int's to unsigned short's. Patch by cras.
734 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
737 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Added TRQ (efficient deque and list library) into lib/trq. This is
742 a very good list library that is currently used in the SILC. Defined
743 SilcList API over the library because I didn't like the API very
744 much. See lib/trq/silclist.h for the API and examples of how to
745 use the API. Fixed various places in the code to use the new
746 SilcList API. The SilcList is meant for lists that has a structure
747 already defined as a list. It is not suitable to add just some
748 context to the list (in TRQ, the context is the list actually).
750 So, I defined SilcDList that can be used for the purpose where
751 predefined list structure does not exit. This can be used as
752 such list. Now some context just can be added to the SilcDList.
753 Currently this list is not used in the SILC just yet, though there
754 are a lot places where this can replace dynamically allocated
755 tables and I will fix these places, later, to use SilcDList.
756 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
757 and use TRQ internally).
759 Also fixed some annoying warning messages that the original TRQ
760 code generated. Also minor changes to TRQ's Makefile.in.
762 * Added support for querying by Client ID to both WHOIS and
763 IDENTIFY commands into server, as required by the protocol.
765 * Removed method function pointers from SilcBuffer structure. They
766 weren't used to anything and just increased the context size for
767 no good reason. This change also made silc_buffer_alloc and
768 silc_buffer_free functions inline functions.
770 * Disabled command flooding detection support until it's fixed so
771 that it accepts commands in but does not execute them more than once
774 * Added silc_net_localhost(), to return local hostname, into
775 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
776 that must be initialized before calling silc_client_init.
778 * Added new function: silc_server_send_notify_on_channels to send
779 notify messages to all channels client has joined. It is assured
780 that the message is sent only once per client.
782 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
783 lib/silcutil/silcutil.[ch] as silc_format function. The new
784 function is generic and is used by server as well, not only by
785 the logging routines.
787 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
788 the provided version string was not acceptable. Added new function:
789 silc_ske_check_version into lib/silcske/silcske.h. The function
790 must be implemented by the application (client or server) and it
791 does not reside in the SKE library. The function checks the version
792 string remote end sent.
794 * Added back pointers (to opaque context and to SilcSocketConnection)
795 into SilcPacketContext structure into lib/silccore/silcpacket.h.
797 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
798 duplicate packet context structure.
800 * Changed `notify' client operation to send same arguments as client
801 receives from server except for ID's. ID's are mapped to correct
802 ID entry and that is returned. Also, if channel entry is not sent
803 by server but the notify is for channel the channel entry is sent
804 to application (otherwise application doesn't know that it is for
805 channel (library gets it from packet's Destination ID)).
807 * Added silc_client_remove_from_channels into client library to
808 remove a client from all channels it has joined to. Used when
809 received SIGNOFF notify from server. Added also new function
810 silc_client_replace_from_channels to replace old ID entry with
811 new ID entry on all channels. Used when received NICK_CHANGE
814 * Fixed ID Cache list handling in silc_idlist_get_client in
815 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
816 to get (or query) client by ID.
820 * Added connection authentication status message defined by the
821 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
822 support for these into the code in client and server side.
824 * Added generic function silc_client_send_command to send any command
825 with variable argument list. Application should use this function
826 to send commands if the command functions provided by the library
827 does not suite for the application's user interface needs.
829 * Added new `failure' client operation. Application is notified about
830 received failure packet if client is executing a protocol. In this
831 case the protocol's execution has failed.
833 * Added SKE's end notify to send the SKE_SUCCESS notify message that
834 is required by the protocol.
836 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
837 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
840 * Added status flag to SilcSKE object to indicate realtime status
843 * Application receives now exactly same command reply arguments as
844 the library receives from server. However, if ID is received the
845 corresponding ID entry is returned to the application (eg. Client
846 ID is mapped to correct SilcClientEntry entry and that is returned).
847 Changed command_reply client operation due to this change.
849 * Changed all ID's in commands and in command replys as ID Payloads.
850 Change affected both client and server side codes.
852 All ID's sent in SILC network (with execption of ID's in SILC
853 Packet header) are sent in ID Payload to support variable length
856 * Server now notifies nick changes and notifies all clients on
857 the channels about the new nickname (about the new Client ID,
860 * Implemented CMODE command to change channel modes. Supports all
861 channel modes defined by the protocol specs except ban and invite
862 lists. (Also, private channel key mode is supported but support for
863 setting private channel key in client is missing, thus, this mode
864 has no effect on client side (except that server requires that the
865 client uses private channel key and normal channel traffic does not
868 Also, invite mode works per se, but INVITE command does not work
869 yet correctly, so you can set channel as invite only channel but
870 inviting clients to the channel does not work (it is yet to be
871 thought what's the best way to do it).
873 * Added new command SILC_COMMAND_CUMODE to change user mode on the
874 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
875 Implemented CUMODE command to change user's mode on the channel.
876 Supports all modes defined by the protocol specs.
878 * Added NAMES command reply to return users modes on the channel.
880 * Removed unnecessary and slow ciphers from lib/silccrypt.
882 * Set SO_KEEPALIVE option to connection sockets by default.
884 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
886 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
887 redefined the Notify Payload into protocol specs.
889 * Added silc_id_payload_parse_id to get ID directly from raw
892 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
894 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
895 accept searching by Client ID as well.
897 * Added support for LEAVE and SIGNOFF notify types in client library.
899 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
900 to parse ID Payload from raw data.
902 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * Added flags parameter into silc_ske_assemble_security_properties
905 function in lib/silcske/silcske.[ch].
907 * Changed notify client operation to fit better for notify messages
908 sent by server. The notify payload received from server is now
909 passed to the application (after parsing it to SilcNotifyPayload).
910 It is application's responsibility to retrieve the arguments
911 from the payload and show the message the way it wants. The message
912 sent by server is implementation specific.
914 * Changed public keys to comply with the protocol specification.
915 Old public keys are not supported anymore and are not compatible.
917 * Removed nickname from Channel Payload as the latest draft removed
918 it. The client must resolve the nickname from the NAMES command
919 reply received when it joined the channel.
921 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
923 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Fixed some errors in protocol specification drafts.
927 * Created lib/silccore/silcnotify.c to implement Notify Payload
928 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
929 generic payloads described by protocol specifications. The file
930 includes implementations for ID Payload and Argument Payload.
932 * Changed Command Payload implementation to use the new Argument
933 Payload. Changed command_xxxx_payload to command_payload_xxxx
934 to comply with SILC coding conventions.
936 * Added suppport for Argument Payload handling in Notify Payload
937 implementation as protocol requires it. Added the new support
938 into server and client lib as well.
940 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Added support for multiple nicknames on same channel. [n] is
943 added locally to the nickname if there are more than one same
944 nicknames on the channel.
946 * Server now sends all nicknames that matched WHOIS request.
947 Client also shows the list received from server.
949 * Added TOPIC command to client side. User can now set and show
950 current topic on channel.
952 * Added MOTD command to client and server. Also, server sends the
953 motd when client connects to the server.
955 * Changed version strings to comply ISO 8601.
957 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Fixed protocol error handling in client library. It should now
960 cope even if the SKE fails for some reason.
962 * Made new protocol specification drafts for submitting to IETF.
964 * Implemented TOPIC command to server in silcd/command.c.
966 * Added two new notify types into lib/silccore/silcnotify.h:
967 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
968 notify nickname change and topic setting/change on a channel.
970 * API change of command_reply operation in client library. The
971 application gets now the status type received from server as well.
973 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
975 * Removed the function just added to lib/silcutil/silcschedule.[ch].
977 * Cras fixed and optimized the packet handling even further and
978 it should work now. Minor change to the prototype of function
979 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
981 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Added new function into lib/silcutil/silcschedule.[ch]:
984 silc_schedule_with_fd to select() a specified fd. The function
985 returns after timeout expires or data arrives or goes. The
986 function is used by packet routines to wait that all data is
987 received from network.
989 * Fixed data reading from network in lib/silccore/silcpacket.c.
990 The code now assures that all data is read from the fd and then
991 continues packet processing. This was a bug fix since the code
992 used to drop some data in some circumstances.
994 * Added new function into lib/silcclient/client.[ch]:
995 silc_client_start_key_exchange to start key exchange after
996 connection has been established to server. The code internally
997 now uses this funtion but its main purpose was to provide it
998 for applications that perform their own connecting. After
999 application has created a connection it merely calls this
1000 function to start the key exchange between client and server.
1001 The library takes care of everything else after that.
1003 Updated also lib/silcclient/README to explain the usage of
1006 * Do not send to application information that connection has
1007 been established. Application gets notified it by connect
1010 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1012 * Applied cras's patch to add silc_schedule_one function. The
1013 function runs scheduler once and returns.
1015 * Fixed the scheduler after cras messed it up. The timeout
1016 handling works now as it's supposed to work.
1018 * Added into lib/silccore/ silcnotify.h to include notify
1019 message types support. Changed silc_server_send_notify*
1020 functions, in server.[ch], to support those new notify types.
1021 Added the support for the notify types into client library,
1022 as well. Added new notify client operation into ops.h in
1025 * Changed silc_server_packet_send_to_channel to send normal
1026 packets instead of just channel message packets. The function
1027 is now used to send the notify packets to channels. It is not
1028 used to send channel message packets anymore, as server never
1031 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1032 va_arg()s as it seems to require it nowadays. I guess, if SILC
1033 is compiled with older va_arg() the new code should work anyway.
1035 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Splitted core library. Core library (lib/silccore) includes
1038 now only SILC protocol specific core (and common) components.
1039 Created new utility library (lib/silcutil) that includes more
1040 generic purpose stuff. The stuff for util library was taken
1041 from the old core library. This was minor and easy split.
1043 * Created SILC Client Library (lib/silcclient) that includes
1044 implementation of the SILC client without user interface. This
1045 was major move from silc/ directory. The code has been changed
1046 so that it is transparent towards the user interface. The
1047 silc/ directory includes now the same user interface as before
1048 and it uses the new client library. Read lib/silcclient/README.
1049 Basicly, the client library performs everything else related
1050 to SILC except user interface handling. Also, configuration
1051 files are considered to be part of user interface and library
1052 does not handle them.
1054 This change also changed a lot of structures, function naming etc.
1055 Most important change was that SilcClientWindow object was
1056 renamed to SilcClientConnection in the client library. Created
1057 also new file lib/silcclient/ops.h. Also added new files
1058 silc/local_command.[ch] and silc/client_ops.[ch].
1060 All these changes were made to make it easier for user interface
1061 designers to create what ever user interface for the SILC client
1064 It is also expected that the server will be moved to lib
1065 directory as well and SILC Server Library will be created;
1066 sometimes in the future.
1068 * Removed Local commands from lib/silccore/silccommand.h as
1069 they are application specific and new client library does not
1070 handle any of those anymore.
1072 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1073 old client implementation in silc/.
1075 * Added support for callback functions in SILC_LOG_* macros.
1076 Application can now set its own callbacks that will be called
1077 instead of using the default functions that will always print
1078 the debug messages to stderr (or stdout). Also, debugging can
1079 now be disabled by setting silc_debug to FALSE and re-enabled by
1080 setting it to TRUE. Note, that logging will still work even
1081 if debugging is disabled.
1083 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1084 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1085 silc_log_reset_debug_callbacks.
1087 * To enable debugging in silc client one must give now -d
1088 option on command line.
1090 * Changed silc_schedule_init to automatically allocate task queues
1091 if they are not allocated before calling it.
1093 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Added GMP 3.1 into math library.
1097 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1100 a channel in SILC network. The packet is used by servers and
1101 routers to notify other routers that user has left a channel.
1102 This little feature was missing until now. Added the feature
1103 to protocol specification as well.
1105 Added functions: silc_server_send_remove_channel_user and
1106 silc_server_remove_channel_user into server.[ch].
1108 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1109 lib/silccore/silcpacket.h. However, they are not implemented
1112 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Fixed joining to a channel and sending channel messages
1115 between server and router. The channel message sending should
1116 now work inside a cell.
1118 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1120 * Fixed the private message sending between server and router.
1121 The private message sending should now work inside a cell.
1123 * Added silc_server_replace_id into server.[ch] to replace
1124 existing ID in the SILC network.
1126 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1127 and silc_idlist_replace_server_id into idlist.[ch] in server.
1129 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Fixed the server to server connections. Server can again now
1132 connect to router. Router to router connections probably does
1135 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Added dynamic protocol registering support. Now protocols can
1138 registered and unregistered on the fly. Patch by cras.
1140 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Added lib/contrib directory to hold routines that some platforms
1143 don't have but are needed by SILC.
1145 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1146 into lin/contrib to provide getopt() and getopt_long() for
1147 those who don't have it.
1149 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Added AWAY command to client. When away message is set and
1152 client receives a private message packet the client automatically
1153 replies to the sender with the away message.
1155 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1156 bug seemed to be the cause of recent problems when compiling
1159 * Added version detection support to SKE protocol specification
1160 and added the new changes to the SKE implementation as well.
1161 There were other minor changes in the SKE protocol as well.
1163 Many changes in lib/silcske/silcske.[ch] and in
1164 lib/silcske/payload.[ch].
1166 * Added ^U functionality, clear input line. Patch from cras.
1168 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Mainly small bugfixes on core library. Fixed some debugging
1171 logging and buffer overflow in silclog.c.
1173 * Updated config.sub and config.guess on the distribution tree.
1175 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1177 * Added command lagging support in server. Client may execute
1178 commands now only once in two seconds.
1180 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Optimized packet reception. MAC computation and checking is now
1183 also more optimized. A lot previously duplicated code is now
1184 used as generic by both client and server.
1186 * Fixed key pair generation in clientutil.c
1188 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Added into lib/silccore/silcbufutil.[ch] new function;
1191 silc_buffer_realloc.
1193 * Moved generic packet sending/encryption functions to
1194 lib/silccore/silcpacket.[ch] from client and server. Some
1195 rewriting of the functions.
1197 * Moved all generic packet reception/decryption functions to
1198 lib/silccore/silcpacket.[ch] from client and server. The
1199 packet processing is now much cleaner in both client and server.
1200 These were major changes in both client and server.
1202 * Created many common functions in server to do packet sending.
1203 Previously code were duplicated a lot, this has been removed
1206 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Rewrote major parts of the ID cache system. Don't know
1209 whether it is better now or not but at least the API is more
1212 * Major rewrite on ID cache stuff on client because of the ID
1213 cache API changes. Added idlist.c to client.
1215 * Also major rewrite on ID cache stuff on server as well.
1216 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1217 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1218 in hand, instead they are all put into the ID cache system now.
1219 All server_idlist_* routines uses ID cache now instead of
1220 traversing its own lists (those lists does not exist anymore).
1221 SilcIDList though still exists. Also, SilcXXXEntry's are
1224 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Finally made the SKE implementation compliant to the protocol
1227 specification. All mp integers are now binary encoded as
1228 opposed being HEX encoded.
1230 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1233 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1234 functions: silc_[encode/decode]_pem. Also added function
1235 silc_encode_pem_file to PEM encode with newlines ('\n') for
1238 * SILC public keys are now encoded either PEM or binary. Same
1239 option is for private keys as well. By default private keys
1240 are binary encoded and public keys PEM encoded. Silly HEX
1241 encoding were removed.
1243 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1244 function to create fingerprints.
1246 * Fixed a bug in SHA1; does not change the original data anymore.
1248 * Partly implemented INFO command on client and server side.
1249 Fixed CLEAR command. Changes to SERVER command; show current
1250 server(s) when giving command without arguments. Added
1251 VERSION command to client.
1253 * Added check to server that unregistered connections cannot
1254 execute commands (unless it is specificly allowed).
1256 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Fixed screen refresh.
1260 * Fixed channel joining bug from client. On some circumstances
1261 client tried to join to a channel it had already joined.
1263 * Added public key verification process into client's protocol.c.
1264 The client now verifies the public key from user and saves
1265 it into ~./silc/serverkeys/ directory.
1267 Added into: clientutil.[ch]: silc_client_verify_server_key.
1269 * Changed SKE protocol's silc_ske_initiator_finish function
1270 to accept callback function that verifies the received public
1271 key. Removed old silc_ske_verify_public_key function.
1273 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1276 silc_pkcs_private_key[_data]_set.
1278 * Made the password and public authentication more cleaner in
1279 server's protocol.c.
1281 * Removed historic and obsolete protocol `channel_auth' from
1282 both client and server.
1284 * Removed wrong way of sending command status messages from
1285 server to client in server's command.c. The old way violated
1286 protocol specification.
1288 Changes to silccore/silccommand.[ch]: removed
1289 silc_command_encode_status_payload -> not needed anymore,
1290 changed silc_command_encode_payload_va to accept extra
1291 argument on variable argument list. The argument type must
1292 now be provided to the function. Also, added new function:
1293 silc_command_encode_reply_payload_va which is same as
1294 normal command_encode_payload_va except command status type
1295 is provided as extra argument.
1297 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1299 * Added ~./silc directory handling. The directory includes the
1300 public and private keys for the client.
1302 Added silc_client_check_silc_dir, silc_client_create_identifier
1303 and silc_client_load_keys.
1305 * Implemented SILC protocol compliant public key. Added public
1306 and private key saving to and loading from files.
1308 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1309 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1310 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1311 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1312 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1314 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1315 silc_pkcs_load_[public/private]_key.
1317 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Added silc_server_get_route (route.[ch]) to get connection
1320 data for the fastest route for given ID.
1322 * Implemented INVITE command on client and server. The command
1323 were re-defined in the SILC Protocol Specification and the
1324 implementation now complies with the specification.
1326 * Implemented PING command on client and server.
1328 * Implemented NAMES command on client and server. The server side
1329 supports currently only normal server not router server yet.
1330 Some changes to NAMES definition in SILC protocol specification.
1332 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Implemented LEAVE command on client and server.
1336 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1337 again. This change was made to the protocol as well. Server
1338 should not violate the protocol specification anymore.
1340 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1343 was tested. SOCKS4 was not but should work anyway.
