3 * Made some sanity checks to silc_server_daemonise like to check
4 whether the reuqested user and group actually exists.
6 * Added sanity check to SKE's silc_ske_responder_finish to check
7 that the public and private key actually is valid.
9 * Invalidate the client's nickname when receiving Replace ID
10 packet and the Client ID is being replaced. This means that the
11 server will query the nickname if someone needs it (client)
14 * Sort the ID Cache in client library when the ID Cache data
15 has changed (needs sorting).
17 * Do not allow for SILC client to create several connections to
18 several servers. The client does not support windows right now
19 and generating multiple connections causes weird behaviour.
21 Irssi-silc client does support windows and can handle several
22 connections without problems, see: www.irssi.org and SILC plugin.
24 * Fixed some places where client was added to the IDList. The
25 rule of thumb is following (in order to get everything right):
26 If the client is directly connected local client then the
27 `connection' argument must be set and `router' argument must be
28 NULL to silc_idlist_add_client function. If the client is not
29 directly connected client then the `router' argument must
30 bet set and the `connection' argument must be NULL to the
31 silc_idlist_add_client function.
33 * The funtion silc_server_packet_send_local_channel actually did
34 not check whether the client was locally connected or not. It
35 does that now. Fixed a bug related to LEAVE command.
37 * Fixed Remove Channel User payload parsing bug in server's
38 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
40 * The server's silc_server_save_channel_key now checks also the
41 global ID list for the channel as it might not be in the local
42 list. Fixed a bug related to LEAVE command.
44 * Is this the end of the [<unknown>] buglet that has been lurking
45 around for a long time? A little for loop fix in server's
46 silc_server_command_whois_parse that is used by both IDENTIFY
47 and WHOIS command. At least, this was a clear bug and a cause
48 of one type of [<unknown>] buglet.
50 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * Added --with-gmp configuration option. If set the GMP
53 is always compiled in the SILC source tree. If not set then
54 it is checked whether the system has the GMP3 installed. If
55 it has then the GMP won't be compiled (the system's headers
56 and library is used), if it doesn't have it then the GMP is
57 compiled in the SILC source tree.
59 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
61 * Changed RSA private exponent generation to what PKCS #1
62 suggests. We try to find the smallest possible d by doing
63 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
64 not security fix but optimization.
66 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * Added new config entry [Identity] to fork the server and run
69 it as specific user and group. A patch from Bostik.
71 * Imported Dotconf configuration library into lib/dotconf.
72 This will be used to create the SILC configuration files later.
73 It will appear in the distsribution after this commit.
75 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
77 * A big code auditing weekend happening. Auditing code for
78 obvious mistakes, bugs and errors. Also, removing any code
81 Removed files for being obsolete:
83 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
84 inline in the file lib/silcutil/silcbuffer.h)
86 o lib/silcutil/silcbufutil.c (the header has inline versions)
88 Changed code to fix possible error conditions:
90 o The buffer formatting routines now check that the destination
91 buffer really has enough space to add the data. This applies for
92 both buffer formatting and unformatting
93 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
94 unformatting was changed to accomodate following rules:
95 XXX_*STRING_ALLOC will allocate space for the data into the pointer
96 sent to the function while XXX_*STRING will not allocate or copy
97 the data into the buffer. Instead it sets the pointer from the
98 buffer into the pointer sent as argument (XXX_*STRING used to
99 require that the pointer must be allocated already). This change
100 makes this whole thing a bit more consistent and more optimized
101 (note that the data returned in the unformatting with XXX_*STRING
102 must not be freed now). The routines return now -1 on error.
104 o Tried to find all code that use buffer_format and buffer_unformat
105 and added return value checking to prevent formatting and
106 especially unformatting errors and possible subsequent fatal
109 o Changed ske->x and ske->KEY to mallocated pointers in
110 lib/silcske/silcske.h. Fixed possible data and memory leak.
112 o Added return value checking to all *_parse* functions. Fixed
113 many memory leaks as well.
115 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
116 so that buffer overflows would not happen. All code now also
117 checks the return value as it can fail.
119 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
121 * Added reconnection support to server if the normal server looses
122 its connection to the router (for example if router is rebooted).
123 The server performs normal reconnection strategy implemented
124 to the server. Affected file silcd/server.c.
126 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
128 * Added new packet type SILC_PACKET_SET_MODE that is used to
129 distribute the information about changed modes (for clients,
130 channels and clients channel modes) to all routers in the
131 network. Updated the protocol specification accordingly.
133 Added functions into silcd/packet_send.c and
134 silcd/packet_receive.c: silc_server_send_set_mode,
135 silc_server_set_mode.
137 Added new files silcmode.[ch] into lib/silccore that implements
138 the encoding and decoding of Set Mode Payload. Added new type
139 SilcSetModePayload. Moved the definitions of different modes
140 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
142 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Oops, a little mistake in server's connection authentication
145 protocol. The protocol is not ended with FAILURE but with
146 SUCCESS if the authentication is Ok. :) Affected file is
149 * Implemented NICK_CHANGE notify handling in server in the file
150 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
151 the local clients on the channel. After the changing nickname
152 in router environment snhould work and the [<unknown>] nickname
153 should appear no more.
155 The silc_server_replace_id function that receives the Replace ID
156 payload now sends the NICK_CHANGE notify type also in the file
157 silcd/packet_receive.c
159 * Changed WHOIS and IDENTIFY command to support the maximum amount
160 of arguments defined in protocol specs (3328 arguments). This
161 fixed a bug that caused problems when there were more than three
164 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
166 * Added extra parameter, command identifier, to the
167 silc_client_send_command so that explicit command identifier
170 Changed that ID list routines uses specific command identifier
171 when sending WHOIS/IDENTIFY requests to the server so that they
172 can be identified when the reply comes back.
174 Affected files lib/silcclient/command.[ch],
175 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
177 * Added `sender' argument to silc_server_packet_send_to_channel
178 to indicaet the sender who originally sent the packet to us
179 that we are now re-sending. Ignored if NULL. Affected file
180 silcd/packet_send.[ch].
182 * Added some server statistics support in silcd/server_internal.h
183 SilcServerStatistics structure and around the server code. Also
184 send some nice statistics information when client is connecting
187 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Fixed channel ID decoding in server's JOIN command reply in
190 silcd/command_reply.c
192 * Fixed braodcasting of replace ID payload to not to send it if
193 we are standalone server in silcd/packet_receive.c.
195 * Fixed all channel message sending routines to not to send
196 packets to clients that has router set, since they are routed
197 separately in the same function earlier. Affects file
198 silcd/packet_send.c and all channel packet sending functions.
200 * In USERS reply, res_argv[i] are not allocated, the table
201 is allocated. Thus changed that free the table, not its
204 * In server's whois_check and identify_check if the client is
205 locally connected do not send any WHOIS commands - they are not
208 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Fixed some minor bugs in client when sending WHOIS command. The
211 arguments was in wrong order.
213 * Removed statis function add_to_channel from server in
214 silcd/command.c that was previously used with the joining but
217 * Tested USERS command in router environment successfully with two
218 routers, two servers and two clients.
220 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
222 * Reorganized the USERS command and command reply in client library
223 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
224 When the command is given by user we register a pending command
225 callback that will reprocess the command after the reply has been
226 received from the server. When reprocessing the packet we then
227 display the information. Thus, the USERS information is displayed
228 now in the command callback instead of in the command reply
229 callback. The processing of the command is same as previously
230 when server has sent the command reply in the JOINing process.
232 * Added to USERS command in silcd/command_reply.c to join the client,
233 we didn't use to know about, to the channel after we've created
234 a client entry for it. Also, for clienet we did know already still
235 check whether it is on the channel or not and add it if not.
237 * Removed silc_server_command_join_notify as the function and its
240 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
242 * Changed the client's pending command handling to the same as the
243 server's pending command handling. It is also now possible to
244 execute command reply functions from other command reply
245 function as the function callbacks for commands and command
246 replies are one and same. The pending commands are not static
247 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
248 in client connection context. Thus, pending commands are server
249 connection specific as it is convenient.
251 Changed the function silc_client_command_pending and
252 silc_client_command_pending_del and added new function
253 silc_client_command_pending_check. Removed the
254 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
257 * Added cmd_ident, current command identifier, to the client
258 connection context in lib/silcclient/client.h to keep track on
259 command identifiers used in command sending. Client's command reply
260 function handling now supports the mandatory command identifiers.
262 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
263 funtions in client to fully support pending command callbacks.
265 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
266 as one of the arguments to the application in the command reply
269 * NOTE: The FORWARDED flag is depracated. It used to be depracated
270 before first releasing SILC but came back. Now it is removed again
271 and should come back nomore. The FORWARDED flag was used only
272 by the JOINing procedure by forwarding the command packet to router.
273 Now, the JOINing procedure has been changed to more generic (due
274 to various router environment issues) and FORWARDED is not needed
275 anymore for anything. The protocol specification is yet to be
278 Now, removed silc_server_packet_forward from server and the flag
279 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
281 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Renamed NAMES command to USERS command. The NAMES was named that
284 due to historical reasons. Now it is renamed. Also, rewrote
285 parts of the USERS command. The nickname list is not sent anymore
286 by the server. Only Client ID and mode lists are sent in the USERS
287 command. Changed this also to the protocol specification.
289 The client now resolves the names and stuff after it receives
290 the USERS list from the server when joining to the channel.
292 * WHOIS and IDENTIFY commands has been changed to support multiple
293 Client ID's per command. One can now search for multiple users
294 in the network by sending only one WHOIS or IDENTIFY command.
295 Changed the code and the protocol specifications.
297 * Removed silc_server_command_identify_parse and changed that IDENTIFY
298 uses silc_server_command_whois_parse to parse the request. */
300 * If normal server, do not parse the WHOIS and IDENTIFY requests
301 before sending it to the router. Saves some time.
303 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Fixed JOIN command on client library. Wrong number of arguments
306 used to crash the client.
308 * Added silc_server_channel_has_global function to check whether
309 channel has global users or not.
311 * Added silc_server_channel_has_local function to check whether channel
312 has locally connected clients on the channel.
314 * The silc_server_remove_from_one_channel now checks whether the
315 channel has global users or not after given client was removed from
316 the channel. It also checks whether the channel has local clients
317 on the channel anymore. If it does not have then the channel entry
318 is removed as it is not needed anymore.
320 * The silc_server_notify now checks on JOIN notify whether the joining
321 client is one of locally connected or global. If it is global then
322 the channel has now global users on the channel and that is marked
323 to the channel entry. Also, it now saves the global client to
324 global list who is joining and JOINs it to the channel. This is
325 for normal server, that is.
327 Changed silc_server_send_notify_on_channel,
328 silc_server_packet_relay_to_channel and
329 silc_server_packet_send_to_channel check if we are normal server
330 and client has router set (ie. global client) do not send the
331 message to that client, as it is already routed to our router.
333 * Implemented LEAVE notify type handling in silc_server_notify
336 * Tested LEAVE command in router environment successfully. Tested
337 with two routers, two servers and two clients.
341 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
343 * Implemented SIGNOFF notify type handling in silc_server_notify
346 * silc_server_remove_id now removes the client entry from all channels
347 it has joined and thusly sends SIGNOFF notify type.
349 * Rewrote the NAMES list generation in server by removing two excess
350 loops. The lists are created now inside one loop.
352 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
354 * silc_server_remove_channel_user checks now also global list
355 for channel and client.
357 * silc_server_new_channel_user checks now both local and global
358 list for channel and client. Fixed a bug in client id decoding.
359 Used to decode wrong buffer.
361 * silc_server_channel_message checks now both local and global
362 list for channel entry.
364 * Tested channel joining (hence JOIN) in router environment
365 successfully. Tested with two routers, two servers and two
368 * Tested channel message sending in router environment successfully.
370 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Added silc_server_save_channel_key into server.[ch] to save the
373 received channel key in Channel Key payload processing. It is
374 also used in JOIN command reply handling.
376 Equivalent function silc_client_save_channel_key added into
377 client.[ch] into client library.
379 * Changed JOIN command reply to send information whether the channel
380 was created or not (is existing already) and the channel key
381 payload. Changed protocol specs accordingly.
383 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
384 the request was sent by ID and not by nickname. Crashed on
387 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
390 now correctly save the received data.
392 * silc_server_free_sock_user_data now notifies routers in the
393 network about entities leaving the network.
395 At the same time implemented functions silc_server_remove_id
396 and silc_server_send_remove_id to receive and send REMOVE_ID
397 packets. The packet is used to notify routers in the network
398 about leaving entities. The ID removed will become invalid in
401 * Added function silc_idlist_del_server into server. Removes and
402 free's server entry from ID list.
404 * silc_server_private_message function now checks, if we are router,
405 that the destination ID really is valid ID, naturally.
407 * In router when NEW_ID packet is received (for new client) the
408 hash of the Client ID is saved in the ID Cache but the
409 client->nickname is set to NULL, instead of putting the hash
412 IDENTIFY command now also checks that client->nickname must be
413 valid. If it is not if will request the data from the server who
414 owns the client. Added new function
415 silc_server_command_identify_check.
417 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
418 to set the command to already allocated Command Payload.
420 * Tested private message sending in router environment with two
421 routers, two servers and two clients. Fixed minor bugs and now
424 * Fixed segfault from client's NAMES command. Used to crash if
427 * Forwarded packets must not be routed even if it is not destined
428 to the receiver. Changed server code comply with this.
430 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Added `require_reverse_mapping' boolean value to ServerParams
433 structure. If TRUE (not default) the server will require that
434 the connecting host has fully qualified domain name.
436 If the reverse mapping is not required and hostname could not be
437 found the IP address is used as hostname.
439 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Implemented version string checking to both client and server.
442 The check is incomplete currently due to the abnormal version
443 strings used in development version of SILC.
445 * Changed all command functions in server to use the new
448 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Changed char *data to unsigned char *data in ID Cache system to
451 support binary data as ID Cache data. Changed code to support
452 binary data in lib/silccore/idcache.c.
454 * Renamed silc_server_packet_relay_command_reply to
455 silc_server_command_reply as it is normal packet receiving
456 function. Rewrote the function to accept command replys for
457 servers and not only for clients.
459 * Mark remote router always as registered server if we are connecting
460 to it. Otherwise, commands sent by the router to us are ignored.
462 * All ID List find routines now returns the ID Cache Entry pointer
463 as well if requested.
465 * WHOIS command works now in router environment, tested with two
466 routers, two servers and two clients.
468 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
469 in router environment (as it is almost equivalent to WHOIS) but
470 hasn't been tested thoroughly. Added new functions:
472 silc_server_command_identify_parse
473 silc_server_command_identify_send_reply
474 silc_server_command_identify_from_client
475 silc_server_command_identify_from_server
477 * Disabled route cache adding because adding two different ID's with
478 same IP replaces the old cache entry thus giving wrong route.
479 The entry->router->connection is always the fastest route anyway
480 so route cache may not be needed. Of course, new routes maybe
481 established after receiving the ID when the entry->router->connection
482 might not be anymore the most optimal.
484 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Add route cache for received ID for fast routing.
488 * Added silc_server_packet_route to route received packet on router
489 that is not destined to us.
491 * Renamed silc_server_get_route to silc_server_route_get.
493 * Added id_string and id_string_len fields into SilcServer to
494 include encoded ServerID for fast comparing without excess
495 encoding of the ID's.
497 * Cleaned up WHOIS command on server side. Added following static
500 silc_server_command_whois_parse
501 silc_server_command_whois_check
502 silc_server_command_whois_send_reply
503 silc_server_command_whois_from_client
504 silc_server_command_whois_from_server
506 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
507 arguments in command replies. All command functions should be
508 updated to use this macro.
510 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Minor typo fixes on command reply handling on server.
514 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
516 * Added silc_server_command_add_to_channel internal routine to add
517 the client to the channel after router has created the channel and
518 sent command reply to the server.
520 * Added generic silc_server_send_command to send any command from
523 * Use static buffer with ID rendering instead of duplicating data.
525 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
527 * Fixed a channel user mode bug when joining to a channel server gave
528 everybody channel founder rights, oops.
530 * We mark ourselves as the router of the incoming server connection
531 if we are router ourselves. This way we can check in some packet
532 sending functions whether it is locally connected server. For
533 incoming router connections we put NULL.
535 * For router sending packets locally means now always sending the
536 packet cell wide; to local clients and local servers. For normal
537 server sending packet locally means sending it to only local
540 * Fixed the JOIN command to really work in router environment. If the
541 channel is created it is always created by the router. Router is
542 also responsible of making the initial joining to the channel,
543 sending JOIN notify to the sending server and distributing
544 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
545 does not exist server doesn't do anything else but forward the
546 command to the router which performs everything.
548 * Added silc_server_send_channel_key function to send the Channel Key
551 * Added silc_server_create_channel_key to create new channel key. The
552 channel key is now re-generated everytime someone joins or leaves
553 a channel, as protocol dictates. Note: channel->key_len is the
556 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
558 * Splitted server.[ch] finally. Created now packet_send.[ch] and
559 packet_receive.[ch] to separate packet sending and receiving
560 routines. The server.[ch] now includes everything else including
561 actual packet processing (writing and reading data) and other
564 Renamed silc_server_private_message_send_internal to
565 silc_server_send_private_message. The routine is still though
566 used only to relay private messages as server does not send
567 private messages itself.
569 Renamed silc_server_new_channel to silc_server_create_new_channel
570 and added new function sicl_server_new_channel that handles the
571 incoming New Channel packet. Added also new sending function
572 silc_server_send_new_channel to send New Channel Payload.
574 * Added new function silc_server_notify to process incoming notify
575 packet to the server/router. Server may then relay the notify
576 to clients if needed.
578 * Added new function silc_server_new_channel_user to process incoming
579 New Channel User packet. Router will redistribute the packet and
580 send JOIN notify to its local clients and locally connected servers
581 if needed. Normal server will send JOIN notify to its local client
582 on same channel when received this packet. Added also corresponding
583 sending function silc_server_send_new_channel_user to sent the
586 * Added boolean route argument to send_notif_to_channel and
587 packet_send_to_channel functions to attempt to route the packet
588 if it is TRUE and send only locally if it is FALSE.
590 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * silc_server_replace_id now broadcasts the received replace ID
593 packet if it is not broadcast packet already. The router must
594 broadcast to inform other routers about changed ID.
596 * Added backpointer to server's router into SilcServer context in
597 silcd/server_internal.h.
599 * Fixed silc_server_packet_broadcast to send correct broadcast
602 * The channel key is now distributed to the local client as soon
603 as it is received from the router (in router environment) so that
604 no other packet may be sent for the channel until client has
607 * silc_server_remove_channel_user now broadcasts the received
608 Remove Channel User packet if it is not broadcast packet already.
609 The router must broadcast to inform other routers about removed
612 * Added users field into SilcPacketContext that is a reference count
613 of the context. One can increase the reference count by calling
614 silc_packet_context_dup which is now changed to just increase the
615 reference count instead of duplicating the data. The reference
616 count is decresed by calling silc_packet_context_free that will
617 free the data after the reference count hits zero.
619 For now on the packet context and everything allocated into it
620 (including the raw packet from network) must be freed by calling
621 the new silc_packet_context_free function. Added also new function
622 silc_packet_context_alloc that must be used now to allocate the
623 context. This also means that if a routine is asynchronous from
624 silc_[client/server]_packet_parse_type the packet context must
625 be duplicated by calling silc_packet_context_dup. Otherwise it
626 gets free'd after silc_[client/server]_packet_parse_type returns.
627 Also, one must remember that if packet is duplicated then its
628 reference count must be decresed by calling the free function as
629 many times as it was duplicated.
631 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
632 from both client and server.
634 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Made joining to a channel working in router environment.
638 * Cleaned up JOIN command on server side and create function
639 silc_server_command_join_channel internal routine to make the
642 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Changed silc_command_pending list to SilcDList. Also, added
645 `ident' field to SilcServerCommandPending structure to identify
646 the reply and to call correct callback.
648 Added silc_server_command_pending_check function to replace the
649 corresnponding macro. The silc_command_pending list is not
652 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
653 to set identifier to previously allocated Command Payload. It
654 is used to set identifier for command when resending Command
657 * Added silc_command_payload_encode_payload to encode Command
658 Payload buffer from SilcCommandPayload structure.
660 * Added silc_argument_payload_encode_payload to encode Argument
661 payload buffer from SilcArgumentPayload structure.
663 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Changed WHOIS command to support router connection on server side.
666 The whois request is always sent to router unless the server is
667 standalone server. After server has received the reply from the
668 router will it send the reply to the client.
670 * Added silc_server_packet_broadcast into silcd/server.[ch] to
671 broadcast received broadcast packet. The function is used only
672 by router. The broadcast packet is always sent to the router's
675 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
676 render given ID to printable string, for log files for example.
678 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
680 * Made basic router to router connections working. At least they
681 can now connect to each other but nothing really works the way
682 they are supposed - yet.
684 * Added new initiator token to RouterConnection configuration
685 file in silcd/serverconfig.[ch]. It is used to tell whether we
686 are the initiator to the remote router or whether we'll expect
687 the other end to connect.
689 * Moved registering of listener task to silc_server_init, hence
690 the server starts listenning as soon as it is run, even if it
691 does not have connections to other routers. Let's see how well
694 * Changed default connection retry timeouts for more suitable in
697 * Removed cipher and such arguments from silc_idlist_add_client
698 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
699 Added new function silc_idlist_add_data to add the keys and stuff
702 * Added SilcIDListData structure and added it to SilcClientEntry
703 and SilcServerEntry as their first field in the structure. This
704 way we can explicitly cast the ID entries to the SilcIDListData
705 structure and get common data for the entries. In past, we had
706 to first check what type of connection it is and then cast it to
707 correct ID entry type. Now, we can directly cast the opaque
708 pointer to the SilcIDListData (no matter what ID entry it actually
709 is) and get the data needed.
711 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Wow, found a bug in scheduler. The scheduler uninitialized itself
714 in some circumstances even if threre were timeout tasks, though not
715 IO tasks, but tasks anyway. Now fixed.
717 * Defined SilcServerConnection structure to hold connection specific
718 stuff about directly connected servers and routers. The definition
719 is currently in silcd/server_internal.h. I thought about having
720 a bit more important role fro this struct but for now it is used
721 only when connecting to other server (or router actually).
723 * Added connecting retry support in server when connecting to
724 router(s). The retry feature implement exponential backoff
725 algorithm. Also, added SilcServerParams structure to hold default
726 parameters for server. For now, it include these retry settings
727 and are hard coded. After server is moded to be as Silc Server
728 Library this structure will be more important.
730 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
732 * Changed client librarys channel->clients table to SilcList and
733 changed code accordingly.
735 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
737 * Changed client's channel table to SilcList and changed code
738 accordingly. Also changed SilcChannelClientEntry to include back-
739 pointer to the channel so that client entry can use that structure
740 as list as well and we have fast cross-reference to the channel.
741 This change dramatically decreased the complexity of channel
742 handling with client entry and vice versa (removed one extra
743 loop when searching for channel entry from many functions).
745 * Changed server->sim from table to SilcDList and changed code
748 * NAMES command can now be used from user interface. It will show
749 the user list on the channel, neatly.
751 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
752 Code now saves realname of the user if it becomes available.
754 * Renamed configure.in to configure.in.pre and made ./prepare
755 script to automatically add correct version string to
756 configure.in which it creates from configure.in.pre.
758 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
760 * NAMES command reply now shows users mode with the nickname when
763 * Moved silc_client_ch[u]mode[_char] functions from
764 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
765 place sucks, they are utility functions and should be in some
768 * Fixed some unsigned int's to unsigned short's. Patch by cras.
770 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
773 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
777 * Added TRQ (efficient deque and list library) into lib/trq. This is
778 a very good list library that is currently used in the SILC. Defined
779 SilcList API over the library because I didn't like the API very
780 much. See lib/trq/silclist.h for the API and examples of how to
781 use the API. Fixed various places in the code to use the new
782 SilcList API. The SilcList is meant for lists that has a structure
783 already defined as a list. It is not suitable to add just some
784 context to the list (in TRQ, the context is the list actually).
786 So, I defined SilcDList that can be used for the purpose where
787 predefined list structure does not exit. This can be used as
788 such list. Now some context just can be added to the SilcDList.
789 Currently this list is not used in the SILC just yet, though there
790 are a lot places where this can replace dynamically allocated
791 tables and I will fix these places, later, to use SilcDList.
792 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
793 and use TRQ internally).
795 Also fixed some annoying warning messages that the original TRQ
796 code generated. Also minor changes to TRQ's Makefile.in.
798 * Added support for querying by Client ID to both WHOIS and
799 IDENTIFY commands into server, as required by the protocol.
801 * Removed method function pointers from SilcBuffer structure. They
802 weren't used to anything and just increased the context size for
803 no good reason. This change also made silc_buffer_alloc and
804 silc_buffer_free functions inline functions.
806 * Disabled command flooding detection support until it's fixed so
807 that it accepts commands in but does not execute them more than once
810 * Added silc_net_localhost(), to return local hostname, into
811 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
812 that must be initialized before calling silc_client_init.
814 * Added new function: silc_server_send_notify_on_channels to send
815 notify messages to all channels client has joined. It is assured
816 that the message is sent only once per client.
818 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
819 lib/silcutil/silcutil.[ch] as silc_format function. The new
820 function is generic and is used by server as well, not only by
821 the logging routines.
823 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
824 the provided version string was not acceptable. Added new function:
825 silc_ske_check_version into lib/silcske/silcske.h. The function
826 must be implemented by the application (client or server) and it
827 does not reside in the SKE library. The function checks the version
828 string remote end sent.
830 * Added back pointers (to opaque context and to SilcSocketConnection)
831 into SilcPacketContext structure into lib/silccore/silcpacket.h.
833 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
834 duplicate packet context structure.
836 * Changed `notify' client operation to send same arguments as client
837 receives from server except for ID's. ID's are mapped to correct
838 ID entry and that is returned. Also, if channel entry is not sent
839 by server but the notify is for channel the channel entry is sent
840 to application (otherwise application doesn't know that it is for
841 channel (library gets it from packet's Destination ID)).
843 * Added silc_client_remove_from_channels into client library to
844 remove a client from all channels it has joined to. Used when
845 received SIGNOFF notify from server. Added also new function
846 silc_client_replace_from_channels to replace old ID entry with
847 new ID entry on all channels. Used when received NICK_CHANGE
850 * Fixed ID Cache list handling in silc_idlist_get_client in
851 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
852 to get (or query) client by ID.
856 * Added connection authentication status message defined by the
857 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
858 support for these into the code in client and server side.
860 * Added generic function silc_client_send_command to send any command
861 with variable argument list. Application should use this function
862 to send commands if the command functions provided by the library
863 does not suite for the application's user interface needs.
865 * Added new `failure' client operation. Application is notified about
866 received failure packet if client is executing a protocol. In this
867 case the protocol's execution has failed.
869 * Added SKE's end notify to send the SKE_SUCCESS notify message that
870 is required by the protocol.
872 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
873 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
876 * Added status flag to SilcSKE object to indicate realtime status
879 * Application receives now exactly same command reply arguments as
880 the library receives from server. However, if ID is received the
881 corresponding ID entry is returned to the application (eg. Client
882 ID is mapped to correct SilcClientEntry entry and that is returned).
883 Changed command_reply client operation due to this change.
885 * Changed all ID's in commands and in command replys as ID Payloads.
886 Change affected both client and server side codes.
888 All ID's sent in SILC network (with execption of ID's in SILC
889 Packet header) are sent in ID Payload to support variable length
892 * Server now notifies nick changes and notifies all clients on
893 the channels about the new nickname (about the new Client ID,
896 * Implemented CMODE command to change channel modes. Supports all
897 channel modes defined by the protocol specs except ban and invite
898 lists. (Also, private channel key mode is supported but support for
899 setting private channel key in client is missing, thus, this mode
900 has no effect on client side (except that server requires that the
901 client uses private channel key and normal channel traffic does not
904 Also, invite mode works per se, but INVITE command does not work
905 yet correctly, so you can set channel as invite only channel but
906 inviting clients to the channel does not work (it is yet to be
907 thought what's the best way to do it).
909 * Added new command SILC_COMMAND_CUMODE to change user mode on the
910 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
911 Implemented CUMODE command to change user's mode on the channel.
912 Supports all modes defined by the protocol specs.
914 * Added NAMES command reply to return users modes on the channel.
916 * Removed unnecessary and slow ciphers from lib/silccrypt.
918 * Set SO_KEEPALIVE option to connection sockets by default.
920 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
922 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
923 redefined the Notify Payload into protocol specs.
925 * Added silc_id_payload_parse_id to get ID directly from raw
928 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
930 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
931 accept searching by Client ID as well.
933 * Added support for LEAVE and SIGNOFF notify types in client library.
935 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
936 to parse ID Payload from raw data.
938 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Added flags parameter into silc_ske_assemble_security_properties
941 function in lib/silcske/silcske.[ch].
943 * Changed notify client operation to fit better for notify messages
944 sent by server. The notify payload received from server is now
945 passed to the application (after parsing it to SilcNotifyPayload).
946 It is application's responsibility to retrieve the arguments
947 from the payload and show the message the way it wants. The message
948 sent by server is implementation specific.
950 * Changed public keys to comply with the protocol specification.
951 Old public keys are not supported anymore and are not compatible.
953 * Removed nickname from Channel Payload as the latest draft removed
954 it. The client must resolve the nickname from the NAMES command
955 reply received when it joined the channel.
957 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
959 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * Fixed some errors in protocol specification drafts.
963 * Created lib/silccore/silcnotify.c to implement Notify Payload
964 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
965 generic payloads described by protocol specifications. The file
966 includes implementations for ID Payload and Argument Payload.
968 * Changed Command Payload implementation to use the new Argument
969 Payload. Changed command_xxxx_payload to command_payload_xxxx
970 to comply with SILC coding conventions.
972 * Added suppport for Argument Payload handling in Notify Payload
973 implementation as protocol requires it. Added the new support
974 into server and client lib as well.
976 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Added support for multiple nicknames on same channel. [n] is
979 added locally to the nickname if there are more than one same
980 nicknames on the channel.
982 * Server now sends all nicknames that matched WHOIS request.
983 Client also shows the list received from server.
985 * Added TOPIC command to client side. User can now set and show
986 current topic on channel.
988 * Added MOTD command to client and server. Also, server sends the
989 motd when client connects to the server.
991 * Changed version strings to comply ISO 8601.
993 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Fixed protocol error handling in client library. It should now
996 cope even if the SKE fails for some reason.
998 * Made new protocol specification drafts for submitting to IETF.
1000 * Implemented TOPIC command to server in silcd/command.c.
1002 * Added two new notify types into lib/silccore/silcnotify.h:
1003 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1004 notify nickname change and topic setting/change on a channel.
1006 * API change of command_reply operation in client library. The
1007 application gets now the status type received from server as well.
1009 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1011 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1013 * Cras fixed and optimized the packet handling even further and
1014 it should work now. Minor change to the prototype of function
1015 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1017 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Added new function into lib/silcutil/silcschedule.[ch]:
1020 silc_schedule_with_fd to select() a specified fd. The function
1021 returns after timeout expires or data arrives or goes. The
1022 function is used by packet routines to wait that all data is
1023 received from network.
1025 * Fixed data reading from network in lib/silccore/silcpacket.c.
1026 The code now assures that all data is read from the fd and then
1027 continues packet processing. This was a bug fix since the code
1028 used to drop some data in some circumstances.
1030 * Added new function into lib/silcclient/client.[ch]:
1031 silc_client_start_key_exchange to start key exchange after
1032 connection has been established to server. The code internally
1033 now uses this funtion but its main purpose was to provide it
1034 for applications that perform their own connecting. After
1035 application has created a connection it merely calls this
1036 function to start the key exchange between client and server.
1037 The library takes care of everything else after that.
1039 Updated also lib/silcclient/README to explain the usage of
1042 * Do not send to application information that connection has
1043 been established. Application gets notified it by connect
1046 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Applied cras's patch to add silc_schedule_one function. The
1049 function runs scheduler once and returns.
1051 * Fixed the scheduler after cras messed it up. The timeout
1052 handling works now as it's supposed to work.
1054 * Added into lib/silccore/ silcnotify.h to include notify
1055 message types support. Changed silc_server_send_notify*
1056 functions, in server.[ch], to support those new notify types.
1057 Added the support for the notify types into client library,
1058 as well. Added new notify client operation into ops.h in
1061 * Changed silc_server_packet_send_to_channel to send normal
1062 packets instead of just channel message packets. The function
1063 is now used to send the notify packets to channels. It is not
1064 used to send channel message packets anymore, as server never
1067 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1068 va_arg()s as it seems to require it nowadays. I guess, if SILC
1069 is compiled with older va_arg() the new code should work anyway.
1071 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * Splitted core library. Core library (lib/silccore) includes
1074 now only SILC protocol specific core (and common) components.
1075 Created new utility library (lib/silcutil) that includes more
1076 generic purpose stuff. The stuff for util library was taken
1077 from the old core library. This was minor and easy split.
1079 * Created SILC Client Library (lib/silcclient) that includes
1080 implementation of the SILC client without user interface. This
1081 was major move from silc/ directory. The code has been changed
1082 so that it is transparent towards the user interface. The
1083 silc/ directory includes now the same user interface as before
1084 and it uses the new client library. Read lib/silcclient/README.
1085 Basicly, the client library performs everything else related
1086 to SILC except user interface handling. Also, configuration
1087 files are considered to be part of user interface and library
1088 does not handle them.
1090 This change also changed a lot of structures, function naming etc.
1091 Most important change was that SilcClientWindow object was
1092 renamed to SilcClientConnection in the client library. Created
1093 also new file lib/silcclient/ops.h. Also added new files
1094 silc/local_command.[ch] and silc/client_ops.[ch].
1096 All these changes were made to make it easier for user interface
1097 designers to create what ever user interface for the SILC client
1100 It is also expected that the server will be moved to lib
1101 directory as well and SILC Server Library will be created;
1102 sometimes in the future.
1104 * Removed Local commands from lib/silccore/silccommand.h as
1105 they are application specific and new client library does not
1106 handle any of those anymore.
1108 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1109 old client implementation in silc/.
1111 * Added support for callback functions in SILC_LOG_* macros.
1112 Application can now set its own callbacks that will be called
1113 instead of using the default functions that will always print
1114 the debug messages to stderr (or stdout). Also, debugging can
1115 now be disabled by setting silc_debug to FALSE and re-enabled by
1116 setting it to TRUE. Note, that logging will still work even
1117 if debugging is disabled.
1119 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1120 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1121 silc_log_reset_debug_callbacks.
1123 * To enable debugging in silc client one must give now -d
1124 option on command line.
1126 * Changed silc_schedule_init to automatically allocate task queues
1127 if they are not allocated before calling it.
1129 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Added GMP 3.1 into math library.
1133 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1136 a channel in SILC network. The packet is used by servers and
1137 routers to notify other routers that user has left a channel.
1138 This little feature was missing until now. Added the feature
1139 to protocol specification as well.
1141 Added functions: silc_server_send_remove_channel_user and
1142 silc_server_remove_channel_user into server.[ch].
1144 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1145 lib/silccore/silcpacket.h. However, they are not implemented
1148 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * Fixed joining to a channel and sending channel messages
1151 between server and router. The channel message sending should
1152 now work inside a cell.
1154 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * Fixed the private message sending between server and router.
1157 The private message sending should now work inside a cell.
1159 * Added silc_server_replace_id into server.[ch] to replace
1160 existing ID in the SILC network.
1162 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1163 and silc_idlist_replace_server_id into idlist.[ch] in server.
1165 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Fixed the server to server connections. Server can again now
1168 connect to router. Router to router connections probably does
1171 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Added dynamic protocol registering support. Now protocols can
1174 registered and unregistered on the fly. Patch by cras.
1176 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Added lib/contrib directory to hold routines that some platforms
1179 don't have but are needed by SILC.
1181 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1182 into lin/contrib to provide getopt() and getopt_long() for
1183 those who don't have it.
1185 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Added AWAY command to client. When away message is set and
1188 client receives a private message packet the client automatically
1189 replies to the sender with the away message.
1191 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1192 bug seemed to be the cause of recent problems when compiling
1195 * Added version detection support to SKE protocol specification
1196 and added the new changes to the SKE implementation as well.
1197 There were other minor changes in the SKE protocol as well.
1199 Many changes in lib/silcske/silcske.[ch] and in
1200 lib/silcske/payload.[ch].
1202 * Added ^U functionality, clear input line. Patch from cras.
1204 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Mainly small bugfixes on core library. Fixed some debugging
1207 logging and buffer overflow in silclog.c.
1209 * Updated config.sub and config.guess on the distribution tree.
1211 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Added command lagging support in server. Client may execute
1214 commands now only once in two seconds.
1216 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Optimized packet reception. MAC computation and checking is now
1219 also more optimized. A lot previously duplicated code is now
1220 used as generic by both client and server.
1222 * Fixed key pair generation in clientutil.c
1224 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Added into lib/silccore/silcbufutil.[ch] new function;
1227 silc_buffer_realloc.
1229 * Moved generic packet sending/encryption functions to
1230 lib/silccore/silcpacket.[ch] from client and server. Some
1231 rewriting of the functions.
1233 * Moved all generic packet reception/decryption functions to
1234 lib/silccore/silcpacket.[ch] from client and server. The
1235 packet processing is now much cleaner in both client and server.
1236 These were major changes in both client and server.
1238 * Created many common functions in server to do packet sending.
1239 Previously code were duplicated a lot, this has been removed
1242 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Rewrote major parts of the ID cache system. Don't know
1245 whether it is better now or not but at least the API is more
1248 * Major rewrite on ID cache stuff on client because of the ID
1249 cache API changes. Added idlist.c to client.
1251 * Also major rewrite on ID cache stuff on server as well.
1252 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1253 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1254 in hand, instead they are all put into the ID cache system now.
1255 All server_idlist_* routines uses ID cache now instead of
1256 traversing its own lists (those lists does not exist anymore).
1257 SilcIDList though still exists. Also, SilcXXXEntry's are
1260 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Finally made the SKE implementation compliant to the protocol
1263 specification. All mp integers are now binary encoded as
1264 opposed being HEX encoded.
1266 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1269 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1270 functions: silc_[encode/decode]_pem. Also added function
1271 silc_encode_pem_file to PEM encode with newlines ('\n') for
1274 * SILC public keys are now encoded either PEM or binary. Same
1275 option is for private keys as well. By default private keys
1276 are binary encoded and public keys PEM encoded. Silly HEX
1277 encoding were removed.
1279 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1280 function to create fingerprints.
1282 * Fixed a bug in SHA1; does not change the original data anymore.
1284 * Partly implemented INFO command on client and server side.
1285 Fixed CLEAR command. Changes to SERVER command; show current
1286 server(s) when giving command without arguments. Added
1287 VERSION command to client.
1289 * Added check to server that unregistered connections cannot
1290 execute commands (unless it is specificly allowed).
1292 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Fixed screen refresh.
1296 * Fixed channel joining bug from client. On some circumstances
1297 client tried to join to a channel it had already joined.
1299 * Added public key verification process into client's protocol.c.
1300 The client now verifies the public key from user and saves
1301 it into ~./silc/serverkeys/ directory.
1303 Added into: clientutil.[ch]: silc_client_verify_server_key.
1305 * Changed SKE protocol's silc_ske_initiator_finish function
1306 to accept callback function that verifies the received public
1307 key. Removed old silc_ske_verify_public_key function.
1309 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1312 silc_pkcs_private_key[_data]_set.
1314 * Made the password and public authentication more cleaner in
1315 server's protocol.c.
1317 * Removed historic and obsolete protocol `channel_auth' from
1318 both client and server.
1320 * Removed wrong way of sending command status messages from
1321 server to client in server's command.c. The old way violated
1322 protocol specification.
1324 Changes to silccore/silccommand.[ch]: removed
1325 silc_command_encode_status_payload -> not needed anymore,
1326 changed silc_command_encode_payload_va to accept extra
1327 argument on variable argument list. The argument type must
1328 now be provided to the function. Also, added new function:
1329 silc_command_encode_reply_payload_va which is same as
1330 normal command_encode_payload_va except command status type
1331 is provided as extra argument.
1333 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1335 * Added ~./silc directory handling. The directory includes the
1336 public and private keys for the client.
1338 Added silc_client_check_silc_dir, silc_client_create_identifier
1339 and silc_client_load_keys.
1341 * Implemented SILC protocol compliant public key. Added public
1342 and private key saving to and loading from files.
1344 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1345 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1346 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1347 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1348 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1350 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1351 silc_pkcs_load_[public/private]_key.
1353 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Added silc_server_get_route (route.[ch]) to get connection
1356 data for the fastest route for given ID.
1358 * Implemented INVITE command on client and server. The command
1359 were re-defined in the SILC Protocol Specification and the
1360 implementation now complies with the specification.
1362 * Implemented PING command on client and server.
1364 * Implemented NAMES command on client and server. The server side
1365 supports currently only normal server not router server yet.
1366 Some changes to NAMES definition in SILC protocol specification.
1368 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1370 * Implemented LEAVE command on client and server.
1372 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1373 again. This change was made to the protocol as well. Server
1374 should not violate the protocol specification anymore.
1376 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1378 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1379 was tested. SOCKS4 was not but should work anyway.
