3 * Added new function silc_server_remove_clients_by_server to
4 remove all client entries from ID list when the server connection
5 is lost. In this case it is also important to invalidate all
6 client entires as they hold the invalid server entry. This
7 fixes fatal bug when server has lost connection and will reconnect
10 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Made some sanity checks to silc_server_daemonise like to check
13 whether the requested user and group actually exists.
15 * Added sanity check to SKE's silc_ske_responder_finish to check
16 that the public and private key actually is valid.
18 * Invalidate the client's nickname when receiving Replace ID
19 packet and the Client ID is being replaced. This means that the
20 server will query the nickname if someone needs it (client)
23 * Sort the ID Cache in client library when the ID Cache data
24 has changed (needs sorting).
26 * Do not allow for SILC client to create several connections to
27 several servers. The client does not support windows right now
28 and generating multiple connections causes weird behaviour.
30 Irssi-silc client does support windows and can handle several
31 connections without problems, see: www.irssi.org and SILC plugin.
33 * Fixed some places where client was added to the IDList. The
34 rule of thumb is following (in order to get everything right):
35 If the client is directly connected local client then the
36 `connection' argument must be set and `router' argument must be
37 NULL to silc_idlist_add_client function. If the client is not
38 directly connected client then the `router' argument must
39 bet set and the `connection' argument must be NULL to the
40 silc_idlist_add_client function.
42 * The funtion silc_server_packet_send_local_channel actually did
43 not check whether the client was locally connected or not. It
44 does that now. Fixed a bug related to LEAVE command.
46 * Fixed Remove Channel User payload parsing bug in server's
47 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
49 * The server's silc_server_save_channel_key now checks also the
50 global ID list for the channel as it might not be in the local
51 list. Fixed a bug related to LEAVE command.
53 * Is this the end of the [<unknown>] buglet that has been lurking
54 around for a long time? A little for loop fix in server's
55 silc_server_command_whois_parse that is used by both IDENTIFY
56 and WHOIS command. At least, this was a clear bug and a cause
57 of one type of [<unknown>] buglet.
59 * WHOIS and IDENTIFY commands call the function
60 silc_server_command_[whois/identify]_check function even if
61 we are not router server.
63 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Added --with-gmp configuration option. If set the GMP
66 is always compiled in the SILC source tree. If not set then
67 it is checked whether the system has the GMP3 installed. If
68 it has then the GMP won't be compiled (the system's headers
69 and library is used), if it doesn't have it then the GMP is
70 compiled in the SILC source tree.
72 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Changed RSA private exponent generation to what PKCS #1
75 suggests. We try to find the smallest possible d by doing
76 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
77 not security fix but optimization.
79 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Added new config entry [Identity] to fork the server and run
82 it as specific user and group. A patch from Bostik.
84 * Imported Dotconf configuration library into lib/dotconf.
85 This will be used to create the SILC configuration files later.
86 It will appear in the distsribution after this commit.
88 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * A big code auditing weekend happening. Auditing code for
91 obvious mistakes, bugs and errors. Also, removing any code
94 Removed files for being obsolete:
96 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
97 inline in the file lib/silcutil/silcbuffer.h)
99 o lib/silcutil/silcbufutil.c (the header has inline versions)
101 Changed code to fix possible error conditions:
103 o The buffer formatting routines now check that the destination
104 buffer really has enough space to add the data. This applies for
105 both buffer formatting and unformatting
106 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
107 unformatting was changed to accomodate following rules:
108 XXX_*STRING_ALLOC will allocate space for the data into the pointer
109 sent to the function while XXX_*STRING will not allocate or copy
110 the data into the buffer. Instead it sets the pointer from the
111 buffer into the pointer sent as argument (XXX_*STRING used to
112 require that the pointer must be allocated already). This change
113 makes this whole thing a bit more consistent and more optimized
114 (note that the data returned in the unformatting with XXX_*STRING
115 must not be freed now). The routines return now -1 on error.
117 o Tried to find all code that use buffer_format and buffer_unformat
118 and added return value checking to prevent formatting and
119 especially unformatting errors and possible subsequent fatal
122 o Changed ske->x and ske->KEY to mallocated pointers in
123 lib/silcske/silcske.h. Fixed possible data and memory leak.
125 o Added return value checking to all *_parse* functions. Fixed
126 many memory leaks as well.
128 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
129 so that buffer overflows would not happen. All code now also
130 checks the return value as it can fail.
132 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
134 * Added reconnection support to server if the normal server looses
135 its connection to the router (for example if router is rebooted).
136 The server performs normal reconnection strategy implemented
137 to the server. Affected file silcd/server.c.
139 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Added new packet type SILC_PACKET_SET_MODE that is used to
142 distribute the information about changed modes (for clients,
143 channels and clients channel modes) to all routers in the
144 network. Updated the protocol specification accordingly.
146 Added functions into silcd/packet_send.c and
147 silcd/packet_receive.c: silc_server_send_set_mode,
148 silc_server_set_mode.
150 Added new files silcmode.[ch] into lib/silccore that implements
151 the encoding and decoding of Set Mode Payload. Added new type
152 SilcSetModePayload. Moved the definitions of different modes
153 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
155 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
157 * Oops, a little mistake in server's connection authentication
158 protocol. The protocol is not ended with FAILURE but with
159 SUCCESS if the authentication is Ok. :) Affected file is
162 * Implemented NICK_CHANGE notify handling in server in the file
163 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
164 the local clients on the channel. After the changing nickname
165 in router environment snhould work and the [<unknown>] nickname
166 should appear no more.
168 The silc_server_replace_id function that receives the Replace ID
169 payload now sends the NICK_CHANGE notify type also in the file
170 silcd/packet_receive.c
172 * Changed WHOIS and IDENTIFY command to support the maximum amount
173 of arguments defined in protocol specs (3328 arguments). This
174 fixed a bug that caused problems when there were more than three
177 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
179 * Added extra parameter, command identifier, to the
180 silc_client_send_command so that explicit command identifier
183 Changed that ID list routines uses specific command identifier
184 when sending WHOIS/IDENTIFY requests to the server so that they
185 can be identified when the reply comes back.
187 Affected files lib/silcclient/command.[ch],
188 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
190 * Added `sender' argument to silc_server_packet_send_to_channel
191 to indicaet the sender who originally sent the packet to us
192 that we are now re-sending. Ignored if NULL. Affected file
193 silcd/packet_send.[ch].
195 * Added some server statistics support in silcd/server_internal.h
196 SilcServerStatistics structure and around the server code. Also
197 send some nice statistics information when client is connecting
200 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
202 * Fixed channel ID decoding in server's JOIN command reply in
203 silcd/command_reply.c
205 * Fixed braodcasting of replace ID payload to not to send it if
206 we are standalone server in silcd/packet_receive.c.
208 * Fixed all channel message sending routines to not to send
209 packets to clients that has router set, since they are routed
210 separately in the same function earlier. Affects file
211 silcd/packet_send.c and all channel packet sending functions.
213 * In USERS reply, res_argv[i] are not allocated, the table
214 is allocated. Thus changed that free the table, not its
217 * In server's whois_check and identify_check if the client is
218 locally connected do not send any WHOIS commands - they are not
221 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Fixed some minor bugs in client when sending WHOIS command. The
224 arguments was in wrong order.
226 * Removed statis function add_to_channel from server in
227 silcd/command.c that was previously used with the joining but
230 * Tested USERS command in router environment successfully with two
231 routers, two servers and two clients.
233 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Reorganized the USERS command and command reply in client library
236 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
237 When the command is given by user we register a pending command
238 callback that will reprocess the command after the reply has been
239 received from the server. When reprocessing the packet we then
240 display the information. Thus, the USERS information is displayed
241 now in the command callback instead of in the command reply
242 callback. The processing of the command is same as previously
243 when server has sent the command reply in the JOINing process.
245 * Added to USERS command in silcd/command_reply.c to join the client,
246 we didn't use to know about, to the channel after we've created
247 a client entry for it. Also, for clienet we did know already still
248 check whether it is on the channel or not and add it if not.
250 * Removed silc_server_command_join_notify as the function and its
253 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Changed the client's pending command handling to the same as the
256 server's pending command handling. It is also now possible to
257 execute command reply functions from other command reply
258 function as the function callbacks for commands and command
259 replies are one and same. The pending commands are not static
260 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
261 in client connection context. Thus, pending commands are server
262 connection specific as it is convenient.
264 Changed the function silc_client_command_pending and
265 silc_client_command_pending_del and added new function
266 silc_client_command_pending_check. Removed the
267 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
270 * Added cmd_ident, current command identifier, to the client
271 connection context in lib/silcclient/client.h to keep track on
272 command identifiers used in command sending. Client's command reply
273 function handling now supports the mandatory command identifiers.
275 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
276 funtions in client to fully support pending command callbacks.
278 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
279 as one of the arguments to the application in the command reply
282 * NOTE: The FORWARDED flag is depracated. It used to be depracated
283 before first releasing SILC but came back. Now it is removed again
284 and should come back nomore. The FORWARDED flag was used only
285 by the JOINing procedure by forwarding the command packet to router.
286 Now, the JOINing procedure has been changed to more generic (due
287 to various router environment issues) and FORWARDED is not needed
288 anymore for anything. The protocol specification is yet to be
291 Now, removed silc_server_packet_forward from server and the flag
292 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
294 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
296 * Renamed NAMES command to USERS command. The NAMES was named that
297 due to historical reasons. Now it is renamed. Also, rewrote
298 parts of the USERS command. The nickname list is not sent anymore
299 by the server. Only Client ID and mode lists are sent in the USERS
300 command. Changed this also to the protocol specification.
302 The client now resolves the names and stuff after it receives
303 the USERS list from the server when joining to the channel.
305 * WHOIS and IDENTIFY commands has been changed to support multiple
306 Client ID's per command. One can now search for multiple users
307 in the network by sending only one WHOIS or IDENTIFY command.
308 Changed the code and the protocol specifications.
310 * Removed silc_server_command_identify_parse and changed that IDENTIFY
311 uses silc_server_command_whois_parse to parse the request. */
313 * If normal server, do not parse the WHOIS and IDENTIFY requests
314 before sending it to the router. Saves some time.
316 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Fixed JOIN command on client library. Wrong number of arguments
319 used to crash the client.
321 * Added silc_server_channel_has_global function to check whether
322 channel has global users or not.
324 * Added silc_server_channel_has_local function to check whether channel
325 has locally connected clients on the channel.
327 * The silc_server_remove_from_one_channel now checks whether the
328 channel has global users or not after given client was removed from
329 the channel. It also checks whether the channel has local clients
330 on the channel anymore. If it does not have then the channel entry
331 is removed as it is not needed anymore.
333 * The silc_server_notify now checks on JOIN notify whether the joining
334 client is one of locally connected or global. If it is global then
335 the channel has now global users on the channel and that is marked
336 to the channel entry. Also, it now saves the global client to
337 global list who is joining and JOINs it to the channel. This is
338 for normal server, that is.
340 Changed silc_server_send_notify_on_channel,
341 silc_server_packet_relay_to_channel and
342 silc_server_packet_send_to_channel check if we are normal server
343 and client has router set (ie. global client) do not send the
344 message to that client, as it is already routed to our router.
346 * Implemented LEAVE notify type handling in silc_server_notify
349 * Tested LEAVE command in router environment successfully. Tested
350 with two routers, two servers and two clients.
354 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
356 * Implemented SIGNOFF notify type handling in silc_server_notify
359 * silc_server_remove_id now removes the client entry from all channels
360 it has joined and thusly sends SIGNOFF notify type.
362 * Rewrote the NAMES list generation in server by removing two excess
363 loops. The lists are created now inside one loop.
365 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * silc_server_remove_channel_user checks now also global list
368 for channel and client.
370 * silc_server_new_channel_user checks now both local and global
371 list for channel and client. Fixed a bug in client id decoding.
372 Used to decode wrong buffer.
374 * silc_server_channel_message checks now both local and global
375 list for channel entry.
377 * Tested channel joining (hence JOIN) in router environment
378 successfully. Tested with two routers, two servers and two
381 * Tested channel message sending in router environment successfully.
383 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Added silc_server_save_channel_key into server.[ch] to save the
386 received channel key in Channel Key payload processing. It is
387 also used in JOIN command reply handling.
389 Equivalent function silc_client_save_channel_key added into
390 client.[ch] into client library.
392 * Changed JOIN command reply to send information whether the channel
393 was created or not (is existing already) and the channel key
394 payload. Changed protocol specs accordingly.
396 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
397 the request was sent by ID and not by nickname. Crashed on
400 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
403 now correctly save the received data.
405 * silc_server_free_sock_user_data now notifies routers in the
406 network about entities leaving the network.
408 At the same time implemented functions silc_server_remove_id
409 and silc_server_send_remove_id to receive and send REMOVE_ID
410 packets. The packet is used to notify routers in the network
411 about leaving entities. The ID removed will become invalid in
414 * Added function silc_idlist_del_server into server. Removes and
415 free's server entry from ID list.
417 * silc_server_private_message function now checks, if we are router,
418 that the destination ID really is valid ID, naturally.
420 * In router when NEW_ID packet is received (for new client) the
421 hash of the Client ID is saved in the ID Cache but the
422 client->nickname is set to NULL, instead of putting the hash
425 IDENTIFY command now also checks that client->nickname must be
426 valid. If it is not if will request the data from the server who
427 owns the client. Added new function
428 silc_server_command_identify_check.
430 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
431 to set the command to already allocated Command Payload.
433 * Tested private message sending in router environment with two
434 routers, two servers and two clients. Fixed minor bugs and now
437 * Fixed segfault from client's NAMES command. Used to crash if
440 * Forwarded packets must not be routed even if it is not destined
441 to the receiver. Changed server code comply with this.
443 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
445 * Added `require_reverse_mapping' boolean value to ServerParams
446 structure. If TRUE (not default) the server will require that
447 the connecting host has fully qualified domain name.
449 If the reverse mapping is not required and hostname could not be
450 found the IP address is used as hostname.
452 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Implemented version string checking to both client and server.
455 The check is incomplete currently due to the abnormal version
456 strings used in development version of SILC.
458 * Changed all command functions in server to use the new
461 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Changed char *data to unsigned char *data in ID Cache system to
464 support binary data as ID Cache data. Changed code to support
465 binary data in lib/silccore/idcache.c.
467 * Renamed silc_server_packet_relay_command_reply to
468 silc_server_command_reply as it is normal packet receiving
469 function. Rewrote the function to accept command replys for
470 servers and not only for clients.
472 * Mark remote router always as registered server if we are connecting
473 to it. Otherwise, commands sent by the router to us are ignored.
475 * All ID List find routines now returns the ID Cache Entry pointer
476 as well if requested.
478 * WHOIS command works now in router environment, tested with two
479 routers, two servers and two clients.
481 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
482 in router environment (as it is almost equivalent to WHOIS) but
483 hasn't been tested thoroughly. Added new functions:
485 silc_server_command_identify_parse
486 silc_server_command_identify_send_reply
487 silc_server_command_identify_from_client
488 silc_server_command_identify_from_server
490 * Disabled route cache adding because adding two different ID's with
491 same IP replaces the old cache entry thus giving wrong route.
492 The entry->router->connection is always the fastest route anyway
493 so route cache may not be needed. Of course, new routes maybe
494 established after receiving the ID when the entry->router->connection
495 might not be anymore the most optimal.
497 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
499 * Add route cache for received ID for fast routing.
501 * Added silc_server_packet_route to route received packet on router
502 that is not destined to us.
504 * Renamed silc_server_get_route to silc_server_route_get.
506 * Added id_string and id_string_len fields into SilcServer to
507 include encoded ServerID for fast comparing without excess
508 encoding of the ID's.
510 * Cleaned up WHOIS command on server side. Added following static
513 silc_server_command_whois_parse
514 silc_server_command_whois_check
515 silc_server_command_whois_send_reply
516 silc_server_command_whois_from_client
517 silc_server_command_whois_from_server
519 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
520 arguments in command replies. All command functions should be
521 updated to use this macro.
523 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
525 * Minor typo fixes on command reply handling on server.
527 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
529 * Added silc_server_command_add_to_channel internal routine to add
530 the client to the channel after router has created the channel and
531 sent command reply to the server.
533 * Added generic silc_server_send_command to send any command from
536 * Use static buffer with ID rendering instead of duplicating data.
538 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
540 * Fixed a channel user mode bug when joining to a channel server gave
541 everybody channel founder rights, oops.
543 * We mark ourselves as the router of the incoming server connection
544 if we are router ourselves. This way we can check in some packet
545 sending functions whether it is locally connected server. For
546 incoming router connections we put NULL.
548 * For router sending packets locally means now always sending the
549 packet cell wide; to local clients and local servers. For normal
550 server sending packet locally means sending it to only local
553 * Fixed the JOIN command to really work in router environment. If the
554 channel is created it is always created by the router. Router is
555 also responsible of making the initial joining to the channel,
556 sending JOIN notify to the sending server and distributing
557 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
558 does not exist server doesn't do anything else but forward the
559 command to the router which performs everything.
561 * Added silc_server_send_channel_key function to send the Channel Key
564 * Added silc_server_create_channel_key to create new channel key. The
565 channel key is now re-generated everytime someone joins or leaves
566 a channel, as protocol dictates. Note: channel->key_len is the
569 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Splitted server.[ch] finally. Created now packet_send.[ch] and
572 packet_receive.[ch] to separate packet sending and receiving
573 routines. The server.[ch] now includes everything else including
574 actual packet processing (writing and reading data) and other
577 Renamed silc_server_private_message_send_internal to
578 silc_server_send_private_message. The routine is still though
579 used only to relay private messages as server does not send
580 private messages itself.
582 Renamed silc_server_new_channel to silc_server_create_new_channel
583 and added new function sicl_server_new_channel that handles the
584 incoming New Channel packet. Added also new sending function
585 silc_server_send_new_channel to send New Channel Payload.
587 * Added new function silc_server_notify to process incoming notify
588 packet to the server/router. Server may then relay the notify
589 to clients if needed.
591 * Added new function silc_server_new_channel_user to process incoming
592 New Channel User packet. Router will redistribute the packet and
593 send JOIN notify to its local clients and locally connected servers
594 if needed. Normal server will send JOIN notify to its local client
595 on same channel when received this packet. Added also corresponding
596 sending function silc_server_send_new_channel_user to sent the
599 * Added boolean route argument to send_notif_to_channel and
600 packet_send_to_channel functions to attempt to route the packet
601 if it is TRUE and send only locally if it is FALSE.
603 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
605 * silc_server_replace_id now broadcasts the received replace ID
606 packet if it is not broadcast packet already. The router must
607 broadcast to inform other routers about changed ID.
609 * Added backpointer to server's router into SilcServer context in
610 silcd/server_internal.h.
612 * Fixed silc_server_packet_broadcast to send correct broadcast
615 * The channel key is now distributed to the local client as soon
616 as it is received from the router (in router environment) so that
617 no other packet may be sent for the channel until client has
620 * silc_server_remove_channel_user now broadcasts the received
621 Remove Channel User packet if it is not broadcast packet already.
622 The router must broadcast to inform other routers about removed
625 * Added users field into SilcPacketContext that is a reference count
626 of the context. One can increase the reference count by calling
627 silc_packet_context_dup which is now changed to just increase the
628 reference count instead of duplicating the data. The reference
629 count is decresed by calling silc_packet_context_free that will
630 free the data after the reference count hits zero.
632 For now on the packet context and everything allocated into it
633 (including the raw packet from network) must be freed by calling
634 the new silc_packet_context_free function. Added also new function
635 silc_packet_context_alloc that must be used now to allocate the
636 context. This also means that if a routine is asynchronous from
637 silc_[client/server]_packet_parse_type the packet context must
638 be duplicated by calling silc_packet_context_dup. Otherwise it
639 gets free'd after silc_[client/server]_packet_parse_type returns.
640 Also, one must remember that if packet is duplicated then its
641 reference count must be decresed by calling the free function as
642 many times as it was duplicated.
644 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
645 from both client and server.
647 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Made joining to a channel working in router environment.
651 * Cleaned up JOIN command on server side and create function
652 silc_server_command_join_channel internal routine to make the
655 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
657 * Changed silc_command_pending list to SilcDList. Also, added
658 `ident' field to SilcServerCommandPending structure to identify
659 the reply and to call correct callback.
661 Added silc_server_command_pending_check function to replace the
662 corresnponding macro. The silc_command_pending list is not
665 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
666 to set identifier to previously allocated Command Payload. It
667 is used to set identifier for command when resending Command
670 * Added silc_command_payload_encode_payload to encode Command
671 Payload buffer from SilcCommandPayload structure.
673 * Added silc_argument_payload_encode_payload to encode Argument
674 payload buffer from SilcArgumentPayload structure.
676 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
678 * Changed WHOIS command to support router connection on server side.
679 The whois request is always sent to router unless the server is
680 standalone server. After server has received the reply from the
681 router will it send the reply to the client.
683 * Added silc_server_packet_broadcast into silcd/server.[ch] to
684 broadcast received broadcast packet. The function is used only
685 by router. The broadcast packet is always sent to the router's
688 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
689 render given ID to printable string, for log files for example.
691 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
693 * Made basic router to router connections working. At least they
694 can now connect to each other but nothing really works the way
695 they are supposed - yet.
697 * Added new initiator token to RouterConnection configuration
698 file in silcd/serverconfig.[ch]. It is used to tell whether we
699 are the initiator to the remote router or whether we'll expect
700 the other end to connect.
702 * Moved registering of listener task to silc_server_init, hence
703 the server starts listenning as soon as it is run, even if it
704 does not have connections to other routers. Let's see how well
707 * Changed default connection retry timeouts for more suitable in
710 * Removed cipher and such arguments from silc_idlist_add_client
711 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
712 Added new function silc_idlist_add_data to add the keys and stuff
715 * Added SilcIDListData structure and added it to SilcClientEntry
716 and SilcServerEntry as their first field in the structure. This
717 way we can explicitly cast the ID entries to the SilcIDListData
718 structure and get common data for the entries. In past, we had
719 to first check what type of connection it is and then cast it to
720 correct ID entry type. Now, we can directly cast the opaque
721 pointer to the SilcIDListData (no matter what ID entry it actually
722 is) and get the data needed.
724 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Wow, found a bug in scheduler. The scheduler uninitialized itself
727 in some circumstances even if threre were timeout tasks, though not
728 IO tasks, but tasks anyway. Now fixed.
730 * Defined SilcServerConnection structure to hold connection specific
731 stuff about directly connected servers and routers. The definition
732 is currently in silcd/server_internal.h. I thought about having
733 a bit more important role fro this struct but for now it is used
734 only when connecting to other server (or router actually).
736 * Added connecting retry support in server when connecting to
737 router(s). The retry feature implement exponential backoff
738 algorithm. Also, added SilcServerParams structure to hold default
739 parameters for server. For now, it include these retry settings
740 and are hard coded. After server is moded to be as Silc Server
741 Library this structure will be more important.
743 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Changed client librarys channel->clients table to SilcList and
746 changed code accordingly.
748 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Changed client's channel table to SilcList and changed code
751 accordingly. Also changed SilcChannelClientEntry to include back-
752 pointer to the channel so that client entry can use that structure
753 as list as well and we have fast cross-reference to the channel.
754 This change dramatically decreased the complexity of channel
755 handling with client entry and vice versa (removed one extra
756 loop when searching for channel entry from many functions).
758 * Changed server->sim from table to SilcDList and changed code
761 * NAMES command can now be used from user interface. It will show
762 the user list on the channel, neatly.
764 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
765 Code now saves realname of the user if it becomes available.
767 * Renamed configure.in to configure.in.pre and made ./prepare
768 script to automatically add correct version string to
769 configure.in which it creates from configure.in.pre.
771 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
773 * NAMES command reply now shows users mode with the nickname when
776 * Moved silc_client_ch[u]mode[_char] functions from
777 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
778 place sucks, they are utility functions and should be in some
781 * Fixed some unsigned int's to unsigned short's. Patch by cras.
783 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
786 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
790 * Added TRQ (efficient deque and list library) into lib/trq. This is
791 a very good list library that is currently used in the SILC. Defined
792 SilcList API over the library because I didn't like the API very
793 much. See lib/trq/silclist.h for the API and examples of how to
794 use the API. Fixed various places in the code to use the new
795 SilcList API. The SilcList is meant for lists that has a structure
796 already defined as a list. It is not suitable to add just some
797 context to the list (in TRQ, the context is the list actually).
799 So, I defined SilcDList that can be used for the purpose where
800 predefined list structure does not exit. This can be used as
801 such list. Now some context just can be added to the SilcDList.
802 Currently this list is not used in the SILC just yet, though there
803 are a lot places where this can replace dynamically allocated
804 tables and I will fix these places, later, to use SilcDList.
805 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
806 and use TRQ internally).
808 Also fixed some annoying warning messages that the original TRQ
809 code generated. Also minor changes to TRQ's Makefile.in.
811 * Added support for querying by Client ID to both WHOIS and
812 IDENTIFY commands into server, as required by the protocol.
814 * Removed method function pointers from SilcBuffer structure. They
815 weren't used to anything and just increased the context size for
816 no good reason. This change also made silc_buffer_alloc and
817 silc_buffer_free functions inline functions.
819 * Disabled command flooding detection support until it's fixed so
820 that it accepts commands in but does not execute them more than once
823 * Added silc_net_localhost(), to return local hostname, into
824 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
825 that must be initialized before calling silc_client_init.
827 * Added new function: silc_server_send_notify_on_channels to send
828 notify messages to all channels client has joined. It is assured
829 that the message is sent only once per client.
831 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
832 lib/silcutil/silcutil.[ch] as silc_format function. The new
833 function is generic and is used by server as well, not only by
834 the logging routines.
836 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
837 the provided version string was not acceptable. Added new function:
838 silc_ske_check_version into lib/silcske/silcske.h. The function
839 must be implemented by the application (client or server) and it
840 does not reside in the SKE library. The function checks the version
841 string remote end sent.
843 * Added back pointers (to opaque context and to SilcSocketConnection)
844 into SilcPacketContext structure into lib/silccore/silcpacket.h.
846 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
847 duplicate packet context structure.
849 * Changed `notify' client operation to send same arguments as client
850 receives from server except for ID's. ID's are mapped to correct
851 ID entry and that is returned. Also, if channel entry is not sent
852 by server but the notify is for channel the channel entry is sent
853 to application (otherwise application doesn't know that it is for
854 channel (library gets it from packet's Destination ID)).
856 * Added silc_client_remove_from_channels into client library to
857 remove a client from all channels it has joined to. Used when
858 received SIGNOFF notify from server. Added also new function
859 silc_client_replace_from_channels to replace old ID entry with
860 new ID entry on all channels. Used when received NICK_CHANGE
863 * Fixed ID Cache list handling in silc_idlist_get_client in
864 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
865 to get (or query) client by ID.
869 * Added connection authentication status message defined by the
870 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
871 support for these into the code in client and server side.
873 * Added generic function silc_client_send_command to send any command
874 with variable argument list. Application should use this function
875 to send commands if the command functions provided by the library
876 does not suite for the application's user interface needs.
878 * Added new `failure' client operation. Application is notified about
879 received failure packet if client is executing a protocol. In this
880 case the protocol's execution has failed.
882 * Added SKE's end notify to send the SKE_SUCCESS notify message that
883 is required by the protocol.
885 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
886 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
889 * Added status flag to SilcSKE object to indicate realtime status
892 * Application receives now exactly same command reply arguments as
893 the library receives from server. However, if ID is received the
894 corresponding ID entry is returned to the application (eg. Client
895 ID is mapped to correct SilcClientEntry entry and that is returned).
896 Changed command_reply client operation due to this change.
898 * Changed all ID's in commands and in command replys as ID Payloads.
899 Change affected both client and server side codes.
901 All ID's sent in SILC network (with execption of ID's in SILC
902 Packet header) are sent in ID Payload to support variable length
905 * Server now notifies nick changes and notifies all clients on
906 the channels about the new nickname (about the new Client ID,
909 * Implemented CMODE command to change channel modes. Supports all
910 channel modes defined by the protocol specs except ban and invite
911 lists. (Also, private channel key mode is supported but support for
912 setting private channel key in client is missing, thus, this mode
913 has no effect on client side (except that server requires that the
914 client uses private channel key and normal channel traffic does not
917 Also, invite mode works per se, but INVITE command does not work
918 yet correctly, so you can set channel as invite only channel but
919 inviting clients to the channel does not work (it is yet to be
920 thought what's the best way to do it).
922 * Added new command SILC_COMMAND_CUMODE to change user mode on the
923 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
924 Implemented CUMODE command to change user's mode on the channel.
925 Supports all modes defined by the protocol specs.
927 * Added NAMES command reply to return users modes on the channel.
929 * Removed unnecessary and slow ciphers from lib/silccrypt.
931 * Set SO_KEEPALIVE option to connection sockets by default.
933 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
935 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
936 redefined the Notify Payload into protocol specs.
938 * Added silc_id_payload_parse_id to get ID directly from raw
941 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
944 accept searching by Client ID as well.
946 * Added support for LEAVE and SIGNOFF notify types in client library.
948 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
949 to parse ID Payload from raw data.
951 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Added flags parameter into silc_ske_assemble_security_properties
954 function in lib/silcske/silcske.[ch].
956 * Changed notify client operation to fit better for notify messages
957 sent by server. The notify payload received from server is now
958 passed to the application (after parsing it to SilcNotifyPayload).
959 It is application's responsibility to retrieve the arguments
960 from the payload and show the message the way it wants. The message
961 sent by server is implementation specific.
963 * Changed public keys to comply with the protocol specification.
964 Old public keys are not supported anymore and are not compatible.
966 * Removed nickname from Channel Payload as the latest draft removed
967 it. The client must resolve the nickname from the NAMES command
968 reply received when it joined the channel.
970 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
972 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Fixed some errors in protocol specification drafts.
976 * Created lib/silccore/silcnotify.c to implement Notify Payload
977 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
978 generic payloads described by protocol specifications. The file
979 includes implementations for ID Payload and Argument Payload.
981 * Changed Command Payload implementation to use the new Argument
982 Payload. Changed command_xxxx_payload to command_payload_xxxx
983 to comply with SILC coding conventions.
985 * Added suppport for Argument Payload handling in Notify Payload
986 implementation as protocol requires it. Added the new support
987 into server and client lib as well.
989 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
991 * Added support for multiple nicknames on same channel. [n] is
992 added locally to the nickname if there are more than one same
993 nicknames on the channel.
995 * Server now sends all nicknames that matched WHOIS request.
996 Client also shows the list received from server.
998 * Added TOPIC command to client side. User can now set and show
999 current topic on channel.
1001 * Added MOTD command to client and server. Also, server sends the
1002 motd when client connects to the server.
1004 * Changed version strings to comply ISO 8601.
1006 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1008 * Fixed protocol error handling in client library. It should now
1009 cope even if the SKE fails for some reason.
1011 * Made new protocol specification drafts for submitting to IETF.
1013 * Implemented TOPIC command to server in silcd/command.c.
1015 * Added two new notify types into lib/silccore/silcnotify.h:
1016 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1017 notify nickname change and topic setting/change on a channel.
1019 * API change of command_reply operation in client library. The
1020 application gets now the status type received from server as well.
1022 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1026 * Cras fixed and optimized the packet handling even further and
1027 it should work now. Minor change to the prototype of function
1028 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1030 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Added new function into lib/silcutil/silcschedule.[ch]:
1033 silc_schedule_with_fd to select() a specified fd. The function
1034 returns after timeout expires or data arrives or goes. The
1035 function is used by packet routines to wait that all data is
1036 received from network.
1038 * Fixed data reading from network in lib/silccore/silcpacket.c.
1039 The code now assures that all data is read from the fd and then
1040 continues packet processing. This was a bug fix since the code
1041 used to drop some data in some circumstances.
1043 * Added new function into lib/silcclient/client.[ch]:
1044 silc_client_start_key_exchange to start key exchange after
1045 connection has been established to server. The code internally
1046 now uses this funtion but its main purpose was to provide it
1047 for applications that perform their own connecting. After
1048 application has created a connection it merely calls this
1049 function to start the key exchange between client and server.
1050 The library takes care of everything else after that.
1052 Updated also lib/silcclient/README to explain the usage of
1055 * Do not send to application information that connection has
1056 been established. Application gets notified it by connect
1059 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1061 * Applied cras's patch to add silc_schedule_one function. The
1062 function runs scheduler once and returns.
1064 * Fixed the scheduler after cras messed it up. The timeout
1065 handling works now as it's supposed to work.
1067 * Added into lib/silccore/ silcnotify.h to include notify
1068 message types support. Changed silc_server_send_notify*
1069 functions, in server.[ch], to support those new notify types.
1070 Added the support for the notify types into client library,
1071 as well. Added new notify client operation into ops.h in
1074 * Changed silc_server_packet_send_to_channel to send normal
1075 packets instead of just channel message packets. The function
1076 is now used to send the notify packets to channels. It is not
1077 used to send channel message packets anymore, as server never
1080 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1081 va_arg()s as it seems to require it nowadays. I guess, if SILC
1082 is compiled with older va_arg() the new code should work anyway.
1084 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Splitted core library. Core library (lib/silccore) includes
1087 now only SILC protocol specific core (and common) components.
1088 Created new utility library (lib/silcutil) that includes more
1089 generic purpose stuff. The stuff for util library was taken
1090 from the old core library. This was minor and easy split.
1092 * Created SILC Client Library (lib/silcclient) that includes
1093 implementation of the SILC client without user interface. This
1094 was major move from silc/ directory. The code has been changed
1095 so that it is transparent towards the user interface. The
1096 silc/ directory includes now the same user interface as before
1097 and it uses the new client library. Read lib/silcclient/README.
1098 Basicly, the client library performs everything else related
1099 to SILC except user interface handling. Also, configuration
1100 files are considered to be part of user interface and library
1101 does not handle them.
1103 This change also changed a lot of structures, function naming etc.
1104 Most important change was that SilcClientWindow object was
1105 renamed to SilcClientConnection in the client library. Created
1106 also new file lib/silcclient/ops.h. Also added new files
1107 silc/local_command.[ch] and silc/client_ops.[ch].
1109 All these changes were made to make it easier for user interface
1110 designers to create what ever user interface for the SILC client
1113 It is also expected that the server will be moved to lib
1114 directory as well and SILC Server Library will be created;
1115 sometimes in the future.
1117 * Removed Local commands from lib/silccore/silccommand.h as
1118 they are application specific and new client library does not
1119 handle any of those anymore.
1121 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1122 old client implementation in silc/.
1124 * Added support for callback functions in SILC_LOG_* macros.
1125 Application can now set its own callbacks that will be called
1126 instead of using the default functions that will always print
1127 the debug messages to stderr (or stdout). Also, debugging can
1128 now be disabled by setting silc_debug to FALSE and re-enabled by
1129 setting it to TRUE. Note, that logging will still work even
1130 if debugging is disabled.
1132 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1133 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1134 silc_log_reset_debug_callbacks.
1136 * To enable debugging in silc client one must give now -d
1137 option on command line.
1139 * Changed silc_schedule_init to automatically allocate task queues
1140 if they are not allocated before calling it.
1142 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Added GMP 3.1 into math library.
1146 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1149 a channel in SILC network. The packet is used by servers and
1150 routers to notify other routers that user has left a channel.
1151 This little feature was missing until now. Added the feature
1152 to protocol specification as well.
1154 Added functions: silc_server_send_remove_channel_user and
1155 silc_server_remove_channel_user into server.[ch].
1157 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1158 lib/silccore/silcpacket.h. However, they are not implemented
1161 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1163 * Fixed joining to a channel and sending channel messages
1164 between server and router. The channel message sending should
1165 now work inside a cell.
1167 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Fixed the private message sending between server and router.
1170 The private message sending should now work inside a cell.
1172 * Added silc_server_replace_id into server.[ch] to replace
1173 existing ID in the SILC network.
1175 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1176 and silc_idlist_replace_server_id into idlist.[ch] in server.
1178 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * Fixed the server to server connections. Server can again now
1181 connect to router. Router to router connections probably does
1184 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Added dynamic protocol registering support. Now protocols can
1187 registered and unregistered on the fly. Patch by cras.
1189 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1191 * Added lib/contrib directory to hold routines that some platforms
1192 don't have but are needed by SILC.
1194 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1195 into lin/contrib to provide getopt() and getopt_long() for
1196 those who don't have it.
1198 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1200 * Added AWAY command to client. When away message is set and
1201 client receives a private message packet the client automatically
1202 replies to the sender with the away message.
1204 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1205 bug seemed to be the cause of recent problems when compiling
1208 * Added version detection support to SKE protocol specification
1209 and added the new changes to the SKE implementation as well.
1210 There were other minor changes in the SKE protocol as well.
1212 Many changes in lib/silcske/silcske.[ch] and in
1213 lib/silcske/payload.[ch].
1215 * Added ^U functionality, clear input line. Patch from cras.
1217 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Mainly small bugfixes on core library. Fixed some debugging
1220 logging and buffer overflow in silclog.c.
1222 * Updated config.sub and config.guess on the distribution tree.
1224 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Added command lagging support in server. Client may execute
1227 commands now only once in two seconds.
1229 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Optimized packet reception. MAC computation and checking is now
1232 also more optimized. A lot previously duplicated code is now
1233 used as generic by both client and server.
1235 * Fixed key pair generation in clientutil.c
1237 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Added into lib/silccore/silcbufutil.[ch] new function;
1240 silc_buffer_realloc.
1242 * Moved generic packet sending/encryption functions to
1243 lib/silccore/silcpacket.[ch] from client and server. Some
1244 rewriting of the functions.
1246 * Moved all generic packet reception/decryption functions to
1247 lib/silccore/silcpacket.[ch] from client and server. The
1248 packet processing is now much cleaner in both client and server.
1249 These were major changes in both client and server.
1251 * Created many common functions in server to do packet sending.
1252 Previously code were duplicated a lot, this has been removed
1255 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1257 * Rewrote major parts of the ID cache system. Don't know
1258 whether it is better now or not but at least the API is more
1261 * Major rewrite on ID cache stuff on client because of the ID
1262 cache API changes. Added idlist.c to client.
1264 * Also major rewrite on ID cache stuff on server as well.
1265 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1266 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1267 in hand, instead they are all put into the ID cache system now.
1268 All server_idlist_* routines uses ID cache now instead of
1269 traversing its own lists (those lists does not exist anymore).
1270 SilcIDList though still exists. Also, SilcXXXEntry's are
1273 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * Finally made the SKE implementation compliant to the protocol
1276 specification. All mp integers are now binary encoded as
1277 opposed being HEX encoded.
1279 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1282 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1283 functions: silc_[encode/decode]_pem. Also added function
1284 silc_encode_pem_file to PEM encode with newlines ('\n') for
1287 * SILC public keys are now encoded either PEM or binary. Same
1288 option is for private keys as well. By default private keys
1289 are binary encoded and public keys PEM encoded. Silly HEX
1290 encoding were removed.
1292 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1293 function to create fingerprints.
1295 * Fixed a bug in SHA1; does not change the original data anymore.
1297 * Partly implemented INFO command on client and server side.
1298 Fixed CLEAR command. Changes to SERVER command; show current
1299 server(s) when giving command without arguments. Added
1300 VERSION command to client.
1302 * Added check to server that unregistered connections cannot
1303 execute commands (unless it is specificly allowed).
1305 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Fixed screen refresh.
1309 * Fixed channel joining bug from client. On some circumstances
1310 client tried to join to a channel it had already joined.
1312 * Added public key verification process into client's protocol.c.
1313 The client now verifies the public key from user and saves
1314 it into ~./silc/serverkeys/ directory.
1316 Added into: clientutil.[ch]: silc_client_verify_server_key.
1318 * Changed SKE protocol's silc_ske_initiator_finish function
1319 to accept callback function that verifies the received public
1320 key. Removed old silc_ske_verify_public_key function.
1322 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1325 silc_pkcs_private_key[_data]_set.
1327 * Made the password and public authentication more cleaner in
1328 server's protocol.c.
1330 * Removed historic and obsolete protocol `channel_auth' from
1331 both client and server.
1333 * Removed wrong way of sending command status messages from
1334 server to client in server's command.c. The old way violated
1335 protocol specification.
1337 Changes to silccore/silccommand.[ch]: removed
1338 silc_command_encode_status_payload -> not needed anymore,
1339 changed silc_command_encode_payload_va to accept extra
1340 argument on variable argument list. The argument type must
1341 now be provided to the function. Also, added new function:
1342 silc_command_encode_reply_payload_va which is same as
1343 normal command_encode_payload_va except command status type
1344 is provided as extra argument.
1346 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * Added ~./silc directory handling. The directory includes the
1349 public and private keys for the client.
1351 Added silc_client_check_silc_dir, silc_client_create_identifier
1352 and silc_client_load_keys.
1354 * Implemented SILC protocol compliant public key. Added public
1355 and private key saving to and loading from files.
1357 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1358 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1359 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1360 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1361 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1363 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1364 silc_pkcs_load_[public/private]_key.
1366 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Added silc_server_get_route (route.[ch]) to get connection
1369 data for the fastest route for given ID.
1371 * Implemented INVITE command on client and server. The command
1372 were re-defined in the SILC Protocol Specification and the
1373 implementation now complies with the specification.
1375 * Implemented PING command on client and server.
1377 * Implemented NAMES command on client and server. The server side
1378 supports currently only normal server not router server yet.
1379 Some changes to NAMES definition in SILC protocol specification.
1381 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Implemented LEAVE command on client and server.
1385 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1386 again. This change was made to the protocol as well. Server
1387 should not violate the protocol specification anymore.
1389 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1391 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1392 was tested. SOCKS4 was not but should work anyway.
