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 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
46 * Added --with-gmp configuration option. If set the GMP
47 is always compiled in the SILC source tree. If not set then
48 it is checked whether the system has the GMP3 installed. If
49 it has then the GMP won't be compiled (the system's headers
50 and library is used), if it doesn't have it then the GMP is
51 compiled in the SILC source tree.
53 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Changed RSA private exponent generation to what PKCS #1
56 suggests. We try to find the smallest possible d by doing
57 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
58 not security fix but optimization.
60 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
62 * Added new config entry [Identity] to fork the server and run
63 it as specific user and group. A patch from Bostik.
65 * Imported Dotconf configuration library into lib/dotconf.
66 This will be used to create the SILC configuration files later.
67 It will appear in the distsribution after this commit.
69 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
71 * A big code auditing weekend happening. Auditing code for
72 obvious mistakes, bugs and errors. Also, removing any code
75 Removed files for being obsolete:
77 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
78 inline in the file lib/silcutil/silcbuffer.h)
80 o lib/silcutil/silcbufutil.c (the header has inline versions)
82 Changed code to fix possible error conditions:
84 o The buffer formatting routines now check that the destination
85 buffer really has enough space to add the data. This applies for
86 both buffer formatting and unformatting
87 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
88 unformatting was changed to accomodate following rules:
89 XXX_*STRING_ALLOC will allocate space for the data into the pointer
90 sent to the function while XXX_*STRING will not allocate or copy
91 the data into the buffer. Instead it sets the pointer from the
92 buffer into the pointer sent as argument (XXX_*STRING used to
93 require that the pointer must be allocated already). This change
94 makes this whole thing a bit more consistent and more optimized
95 (note that the data returned in the unformatting with XXX_*STRING
96 must not be freed now). The routines return now -1 on error.
98 o Tried to find all code that use buffer_format and buffer_unformat
99 and added return value checking to prevent formatting and
100 especially unformatting errors and possible subsequent fatal
103 o Changed ske->x and ske->KEY to mallocated pointers in
104 lib/silcske/silcske.h. Fixed possible data and memory leak.
106 o Added return value checking to all *_parse* functions. Fixed
107 many memory leaks as well.
109 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
110 so that buffer overflows would not happen. All code now also
111 checks the return value as it can fail.
113 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * Added reconnection support to server if the normal server looses
116 its connection to the router (for example if router is rebooted).
117 The server performs normal reconnection strategy implemented
118 to the server. Affected file silcd/server.c.
120 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
122 * Added new packet type SILC_PACKET_SET_MODE that is used to
123 distribute the information about changed modes (for clients,
124 channels and clients channel modes) to all routers in the
125 network. Updated the protocol specification accordingly.
127 Added functions into silcd/packet_send.c and
128 silcd/packet_receive.c: silc_server_send_set_mode,
129 silc_server_set_mode.
131 Added new files silcmode.[ch] into lib/silccore that implements
132 the encoding and decoding of Set Mode Payload. Added new type
133 SilcSetModePayload. Moved the definitions of different modes
134 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
136 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Oops, a little mistake in server's connection authentication
139 protocol. The protocol is not ended with FAILURE but with
140 SUCCESS if the authentication is Ok. :) Affected file is
143 * Implemented NICK_CHANGE notify handling in server in the file
144 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
145 the local clients on the channel. After the changing nickname
146 in router environment snhould work and the [<unknown>] nickname
147 should appear no more.
149 The silc_server_replace_id function that receives the Replace ID
150 payload now sends the NICK_CHANGE notify type also in the file
151 silcd/packet_receive.c
153 * Changed WHOIS and IDENTIFY command to support the maximum amount
154 of arguments defined in protocol specs (3328 arguments). This
155 fixed a bug that caused problems when there were more than three
158 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
160 * Added extra parameter, command identifier, to the
161 silc_client_send_command so that explicit command identifier
164 Changed that ID list routines uses specific command identifier
165 when sending WHOIS/IDENTIFY requests to the server so that they
166 can be identified when the reply comes back.
168 Affected files lib/silcclient/command.[ch],
169 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
171 * Added `sender' argument to silc_server_packet_send_to_channel
172 to indicaet the sender who originally sent the packet to us
173 that we are now re-sending. Ignored if NULL. Affected file
174 silcd/packet_send.[ch].
176 * Added some server statistics support in silcd/server_internal.h
177 SilcServerStatistics structure and around the server code. Also
178 send some nice statistics information when client is connecting
181 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
183 * Fixed channel ID decoding in server's JOIN command reply in
184 silcd/command_reply.c
186 * Fixed braodcasting of replace ID payload to not to send it if
187 we are standalone server in silcd/packet_receive.c.
189 * Fixed all channel message sending routines to not to send
190 packets to clients that has router set, since they are routed
191 separately in the same function earlier. Affects file
192 silcd/packet_send.c and all channel packet sending functions.
194 * In USERS reply, res_argv[i] are not allocated, the table
195 is allocated. Thus changed that free the table, not its
198 * In server's whois_check and identify_check if the client is
199 locally connected do not send any WHOIS commands - they are not
202 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
204 * Fixed some minor bugs in client when sending WHOIS command. The
205 arguments was in wrong order.
207 * Removed statis function add_to_channel from server in
208 silcd/command.c that was previously used with the joining but
211 * Tested USERS command in router environment successfully with two
212 routers, two servers and two clients.
214 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
216 * Reorganized the USERS command and command reply in client library
217 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
218 When the command is given by user we register a pending command
219 callback that will reprocess the command after the reply has been
220 received from the server. When reprocessing the packet we then
221 display the information. Thus, the USERS information is displayed
222 now in the command callback instead of in the command reply
223 callback. The processing of the command is same as previously
224 when server has sent the command reply in the JOINing process.
226 * Added to USERS command in silcd/command_reply.c to join the client,
227 we didn't use to know about, to the channel after we've created
228 a client entry for it. Also, for clienet we did know already still
229 check whether it is on the channel or not and add it if not.
231 * Removed silc_server_command_join_notify as the function and its
234 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Changed the client's pending command handling to the same as the
237 server's pending command handling. It is also now possible to
238 execute command reply functions from other command reply
239 function as the function callbacks for commands and command
240 replies are one and same. The pending commands are not static
241 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
242 in client connection context. Thus, pending commands are server
243 connection specific as it is convenient.
245 Changed the function silc_client_command_pending and
246 silc_client_command_pending_del and added new function
247 silc_client_command_pending_check. Removed the
248 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
251 * Added cmd_ident, current command identifier, to the client
252 connection context in lib/silcclient/client.h to keep track on
253 command identifiers used in command sending. Client's command reply
254 function handling now supports the mandatory command identifiers.
256 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
257 funtions in client to fully support pending command callbacks.
259 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
260 as one of the arguments to the application in the command reply
263 * NOTE: The FORWARDED flag is depracated. It used to be depracated
264 before first releasing SILC but came back. Now it is removed again
265 and should come back nomore. The FORWARDED flag was used only
266 by the JOINing procedure by forwarding the command packet to router.
267 Now, the JOINing procedure has been changed to more generic (due
268 to various router environment issues) and FORWARDED is not needed
269 anymore for anything. The protocol specification is yet to be
272 Now, removed silc_server_packet_forward from server and the flag
273 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
275 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Renamed NAMES command to USERS command. The NAMES was named that
278 due to historical reasons. Now it is renamed. Also, rewrote
279 parts of the USERS command. The nickname list is not sent anymore
280 by the server. Only Client ID and mode lists are sent in the USERS
281 command. Changed this also to the protocol specification.
283 The client now resolves the names and stuff after it receives
284 the USERS list from the server when joining to the channel.
286 * WHOIS and IDENTIFY commands has been changed to support multiple
287 Client ID's per command. One can now search for multiple users
288 in the network by sending only one WHOIS or IDENTIFY command.
289 Changed the code and the protocol specifications.
291 * Removed silc_server_command_identify_parse and changed that IDENTIFY
292 uses silc_server_command_whois_parse to parse the request. */
294 * If normal server, do not parse the WHOIS and IDENTIFY requests
295 before sending it to the router. Saves some time.
297 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
299 * Fixed JOIN command on client library. Wrong number of arguments
300 used to crash the client.
302 * Added silc_server_channel_has_global function to check whether
303 channel has global users or not.
305 * Added silc_server_channel_has_local function to check whether channel
306 has locally connected clients on the channel.
308 * The silc_server_remove_from_one_channel now checks whether the
309 channel has global users or not after given client was removed from
310 the channel. It also checks whether the channel has local clients
311 on the channel anymore. If it does not have then the channel entry
312 is removed as it is not needed anymore.
314 * The silc_server_notify now checks on JOIN notify whether the joining
315 client is one of locally connected or global. If it is global then
316 the channel has now global users on the channel and that is marked
317 to the channel entry. Also, it now saves the global client to
318 global list who is joining and JOINs it to the channel. This is
319 for normal server, that is.
321 Changed silc_server_send_notify_on_channel,
322 silc_server_packet_relay_to_channel and
323 silc_server_packet_send_to_channel check if we are normal server
324 and client has router set (ie. global client) do not send the
325 message to that client, as it is already routed to our router.
327 * Implemented LEAVE notify type handling in silc_server_notify
330 * Tested LEAVE command in router environment successfully. Tested
331 with two routers, two servers and two clients.
335 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
337 * Implemented SIGNOFF notify type handling in silc_server_notify
340 * silc_server_remove_id now removes the client entry from all channels
341 it has joined and thusly sends SIGNOFF notify type.
343 * Rewrote the NAMES list generation in server by removing two excess
344 loops. The lists are created now inside one loop.
346 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * silc_server_remove_channel_user checks now also global list
349 for channel and client.
351 * silc_server_new_channel_user checks now both local and global
352 list for channel and client. Fixed a bug in client id decoding.
353 Used to decode wrong buffer.
355 * silc_server_channel_message checks now both local and global
356 list for channel entry.
358 * Tested channel joining (hence JOIN) in router environment
359 successfully. Tested with two routers, two servers and two
362 * Tested channel message sending in router environment successfully.
364 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Added silc_server_save_channel_key into server.[ch] to save the
367 received channel key in Channel Key payload processing. It is
368 also used in JOIN command reply handling.
370 Equivalent function silc_client_save_channel_key added into
371 client.[ch] into client library.
373 * Changed JOIN command reply to send information whether the channel
374 was created or not (is existing already) and the channel key
375 payload. Changed protocol specs accordingly.
377 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
378 the request was sent by ID and not by nickname. Crashed on
381 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
384 now correctly save the received data.
386 * silc_server_free_sock_user_data now notifies routers in the
387 network about entities leaving the network.
389 At the same time implemented functions silc_server_remove_id
390 and silc_server_send_remove_id to receive and send REMOVE_ID
391 packets. The packet is used to notify routers in the network
392 about leaving entities. The ID removed will become invalid in
395 * Added function silc_idlist_del_server into server. Removes and
396 free's server entry from ID list.
398 * silc_server_private_message function now checks, if we are router,
399 that the destination ID really is valid ID, naturally.
401 * In router when NEW_ID packet is received (for new client) the
402 hash of the Client ID is saved in the ID Cache but the
403 client->nickname is set to NULL, instead of putting the hash
406 IDENTIFY command now also checks that client->nickname must be
407 valid. If it is not if will request the data from the server who
408 owns the client. Added new function
409 silc_server_command_identify_check.
411 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
412 to set the command to already allocated Command Payload.
414 * Tested private message sending in router environment with two
415 routers, two servers and two clients. Fixed minor bugs and now
418 * Fixed segfault from client's NAMES command. Used to crash if
421 * Forwarded packets must not be routed even if it is not destined
422 to the receiver. Changed server code comply with this.
424 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
426 * Added `require_reverse_mapping' boolean value to ServerParams
427 structure. If TRUE (not default) the server will require that
428 the connecting host has fully qualified domain name.
430 If the reverse mapping is not required and hostname could not be
431 found the IP address is used as hostname.
433 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
435 * Implemented version string checking to both client and server.
436 The check is incomplete currently due to the abnormal version
437 strings used in development version of SILC.
439 * Changed all command functions in server to use the new
442 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
444 * Changed char *data to unsigned char *data in ID Cache system to
445 support binary data as ID Cache data. Changed code to support
446 binary data in lib/silccore/idcache.c.
448 * Renamed silc_server_packet_relay_command_reply to
449 silc_server_command_reply as it is normal packet receiving
450 function. Rewrote the function to accept command replys for
451 servers and not only for clients.
453 * Mark remote router always as registered server if we are connecting
454 to it. Otherwise, commands sent by the router to us are ignored.
456 * All ID List find routines now returns the ID Cache Entry pointer
457 as well if requested.
459 * WHOIS command works now in router environment, tested with two
460 routers, two servers and two clients.
462 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
463 in router environment (as it is almost equivalent to WHOIS) but
464 hasn't been tested thoroughly. Added new functions:
466 silc_server_command_identify_parse
467 silc_server_command_identify_send_reply
468 silc_server_command_identify_from_client
469 silc_server_command_identify_from_server
471 * Disabled route cache adding because adding two different ID's with
472 same IP replaces the old cache entry thus giving wrong route.
473 The entry->router->connection is always the fastest route anyway
474 so route cache may not be needed. Of course, new routes maybe
475 established after receiving the ID when the entry->router->connection
476 might not be anymore the most optimal.
478 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
480 * Add route cache for received ID for fast routing.
482 * Added silc_server_packet_route to route received packet on router
483 that is not destined to us.
485 * Renamed silc_server_get_route to silc_server_route_get.
487 * Added id_string and id_string_len fields into SilcServer to
488 include encoded ServerID for fast comparing without excess
489 encoding of the ID's.
491 * Cleaned up WHOIS command on server side. Added following static
494 silc_server_command_whois_parse
495 silc_server_command_whois_check
496 silc_server_command_whois_send_reply
497 silc_server_command_whois_from_client
498 silc_server_command_whois_from_server
500 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
501 arguments in command replies. All command functions should be
502 updated to use this macro.
504 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Minor typo fixes on command reply handling on server.
508 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Added silc_server_command_add_to_channel internal routine to add
511 the client to the channel after router has created the channel and
512 sent command reply to the server.
514 * Added generic silc_server_send_command to send any command from
517 * Use static buffer with ID rendering instead of duplicating data.
519 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Fixed a channel user mode bug when joining to a channel server gave
522 everybody channel founder rights, oops.
524 * We mark ourselves as the router of the incoming server connection
525 if we are router ourselves. This way we can check in some packet
526 sending functions whether it is locally connected server. For
527 incoming router connections we put NULL.
529 * For router sending packets locally means now always sending the
530 packet cell wide; to local clients and local servers. For normal
531 server sending packet locally means sending it to only local
534 * Fixed the JOIN command to really work in router environment. If the
535 channel is created it is always created by the router. Router is
536 also responsible of making the initial joining to the channel,
537 sending JOIN notify to the sending server and distributing
538 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
539 does not exist server doesn't do anything else but forward the
540 command to the router which performs everything.
542 * Added silc_server_send_channel_key function to send the Channel Key
545 * Added silc_server_create_channel_key to create new channel key. The
546 channel key is now re-generated everytime someone joins or leaves
547 a channel, as protocol dictates. Note: channel->key_len is the
550 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
552 * Splitted server.[ch] finally. Created now packet_send.[ch] and
553 packet_receive.[ch] to separate packet sending and receiving
554 routines. The server.[ch] now includes everything else including
555 actual packet processing (writing and reading data) and other
558 Renamed silc_server_private_message_send_internal to
559 silc_server_send_private_message. The routine is still though
560 used only to relay private messages as server does not send
561 private messages itself.
563 Renamed silc_server_new_channel to silc_server_create_new_channel
564 and added new function sicl_server_new_channel that handles the
565 incoming New Channel packet. Added also new sending function
566 silc_server_send_new_channel to send New Channel Payload.
568 * Added new function silc_server_notify to process incoming notify
569 packet to the server/router. Server may then relay the notify
570 to clients if needed.
572 * Added new function silc_server_new_channel_user to process incoming
573 New Channel User packet. Router will redistribute the packet and
574 send JOIN notify to its local clients and locally connected servers
575 if needed. Normal server will send JOIN notify to its local client
576 on same channel when received this packet. Added also corresponding
577 sending function silc_server_send_new_channel_user to sent the
580 * Added boolean route argument to send_notif_to_channel and
581 packet_send_to_channel functions to attempt to route the packet
582 if it is TRUE and send only locally if it is FALSE.
584 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
586 * silc_server_replace_id now broadcasts the received replace ID
587 packet if it is not broadcast packet already. The router must
588 broadcast to inform other routers about changed ID.
590 * Added backpointer to server's router into SilcServer context in
591 silcd/server_internal.h.
593 * Fixed silc_server_packet_broadcast to send correct broadcast
596 * The channel key is now distributed to the local client as soon
597 as it is received from the router (in router environment) so that
598 no other packet may be sent for the channel until client has
601 * silc_server_remove_channel_user now broadcasts the received
602 Remove Channel User packet if it is not broadcast packet already.
603 The router must broadcast to inform other routers about removed
606 * Added users field into SilcPacketContext that is a reference count
607 of the context. One can increase the reference count by calling
608 silc_packet_context_dup which is now changed to just increase the
609 reference count instead of duplicating the data. The reference
610 count is decresed by calling silc_packet_context_free that will
611 free the data after the reference count hits zero.
613 For now on the packet context and everything allocated into it
614 (including the raw packet from network) must be freed by calling
615 the new silc_packet_context_free function. Added also new function
616 silc_packet_context_alloc that must be used now to allocate the
617 context. This also means that if a routine is asynchronous from
618 silc_[client/server]_packet_parse_type the packet context must
619 be duplicated by calling silc_packet_context_dup. Otherwise it
620 gets free'd after silc_[client/server]_packet_parse_type returns.
621 Also, one must remember that if packet is duplicated then its
622 reference count must be decresed by calling the free function as
623 many times as it was duplicated.
625 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
626 from both client and server.
628 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
630 * Made joining to a channel working in router environment.
632 * Cleaned up JOIN command on server side and create function
633 silc_server_command_join_channel internal routine to make the
636 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Changed silc_command_pending list to SilcDList. Also, added
639 `ident' field to SilcServerCommandPending structure to identify
640 the reply and to call correct callback.
642 Added silc_server_command_pending_check function to replace the
643 corresnponding macro. The silc_command_pending list is not
646 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
647 to set identifier to previously allocated Command Payload. It
648 is used to set identifier for command when resending Command
651 * Added silc_command_payload_encode_payload to encode Command
652 Payload buffer from SilcCommandPayload structure.
654 * Added silc_argument_payload_encode_payload to encode Argument
655 payload buffer from SilcArgumentPayload structure.
657 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
659 * Changed WHOIS command to support router connection on server side.
660 The whois request is always sent to router unless the server is
661 standalone server. After server has received the reply from the
662 router will it send the reply to the client.
664 * Added silc_server_packet_broadcast into silcd/server.[ch] to
665 broadcast received broadcast packet. The function is used only
666 by router. The broadcast packet is always sent to the router's
669 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
670 render given ID to printable string, for log files for example.
672 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Made basic router to router connections working. At least they
675 can now connect to each other but nothing really works the way
676 they are supposed - yet.
678 * Added new initiator token to RouterConnection configuration
679 file in silcd/serverconfig.[ch]. It is used to tell whether we
680 are the initiator to the remote router or whether we'll expect
681 the other end to connect.
683 * Moved registering of listener task to silc_server_init, hence
684 the server starts listenning as soon as it is run, even if it
685 does not have connections to other routers. Let's see how well
688 * Changed default connection retry timeouts for more suitable in
691 * Removed cipher and such arguments from silc_idlist_add_client
692 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
693 Added new function silc_idlist_add_data to add the keys and stuff
696 * Added SilcIDListData structure and added it to SilcClientEntry
697 and SilcServerEntry as their first field in the structure. This
698 way we can explicitly cast the ID entries to the SilcIDListData
699 structure and get common data for the entries. In past, we had
700 to first check what type of connection it is and then cast it to
701 correct ID entry type. Now, we can directly cast the opaque
702 pointer to the SilcIDListData (no matter what ID entry it actually
703 is) and get the data needed.
705 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * Wow, found a bug in scheduler. The scheduler uninitialized itself
708 in some circumstances even if threre were timeout tasks, though not
709 IO tasks, but tasks anyway. Now fixed.
711 * Defined SilcServerConnection structure to hold connection specific
712 stuff about directly connected servers and routers. The definition
713 is currently in silcd/server_internal.h. I thought about having
714 a bit more important role fro this struct but for now it is used
715 only when connecting to other server (or router actually).
717 * Added connecting retry support in server when connecting to
718 router(s). The retry feature implement exponential backoff
719 algorithm. Also, added SilcServerParams structure to hold default
720 parameters for server. For now, it include these retry settings
721 and are hard coded. After server is moded to be as Silc Server
722 Library this structure will be more important.
724 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Changed client librarys channel->clients table to SilcList and
727 changed code accordingly.
729 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Changed client's channel table to SilcList and changed code
732 accordingly. Also changed SilcChannelClientEntry to include back-
733 pointer to the channel so that client entry can use that structure
734 as list as well and we have fast cross-reference to the channel.
735 This change dramatically decreased the complexity of channel
736 handling with client entry and vice versa (removed one extra
737 loop when searching for channel entry from many functions).
739 * Changed server->sim from table to SilcDList and changed code
742 * NAMES command can now be used from user interface. It will show
743 the user list on the channel, neatly.
745 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
746 Code now saves realname of the user if it becomes available.
748 * Renamed configure.in to configure.in.pre and made ./prepare
749 script to automatically add correct version string to
750 configure.in which it creates from configure.in.pre.
752 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * NAMES command reply now shows users mode with the nickname when
757 * Moved silc_client_ch[u]mode[_char] functions from
758 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
759 place sucks, they are utility functions and should be in some
762 * Fixed some unsigned int's to unsigned short's. Patch by cras.
764 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
767 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Added TRQ (efficient deque and list library) into lib/trq. This is
772 a very good list library that is currently used in the SILC. Defined
773 SilcList API over the library because I didn't like the API very
774 much. See lib/trq/silclist.h for the API and examples of how to
775 use the API. Fixed various places in the code to use the new
776 SilcList API. The SilcList is meant for lists that has a structure
777 already defined as a list. It is not suitable to add just some
778 context to the list (in TRQ, the context is the list actually).
780 So, I defined SilcDList that can be used for the purpose where
781 predefined list structure does not exit. This can be used as
782 such list. Now some context just can be added to the SilcDList.
783 Currently this list is not used in the SILC just yet, though there
784 are a lot places where this can replace dynamically allocated
785 tables and I will fix these places, later, to use SilcDList.
786 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
787 and use TRQ internally).
789 Also fixed some annoying warning messages that the original TRQ
790 code generated. Also minor changes to TRQ's Makefile.in.
792 * Added support for querying by Client ID to both WHOIS and
793 IDENTIFY commands into server, as required by the protocol.
795 * Removed method function pointers from SilcBuffer structure. They
796 weren't used to anything and just increased the context size for
797 no good reason. This change also made silc_buffer_alloc and
798 silc_buffer_free functions inline functions.
800 * Disabled command flooding detection support until it's fixed so
801 that it accepts commands in but does not execute them more than once
804 * Added silc_net_localhost(), to return local hostname, into
805 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
806 that must be initialized before calling silc_client_init.
808 * Added new function: silc_server_send_notify_on_channels to send
809 notify messages to all channels client has joined. It is assured
810 that the message is sent only once per client.
812 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
813 lib/silcutil/silcutil.[ch] as silc_format function. The new
814 function is generic and is used by server as well, not only by
815 the logging routines.
817 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
818 the provided version string was not acceptable. Added new function:
819 silc_ske_check_version into lib/silcske/silcske.h. The function
820 must be implemented by the application (client or server) and it
821 does not reside in the SKE library. The function checks the version
822 string remote end sent.
824 * Added back pointers (to opaque context and to SilcSocketConnection)
825 into SilcPacketContext structure into lib/silccore/silcpacket.h.
827 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
828 duplicate packet context structure.
830 * Changed `notify' client operation to send same arguments as client
831 receives from server except for ID's. ID's are mapped to correct
832 ID entry and that is returned. Also, if channel entry is not sent
833 by server but the notify is for channel the channel entry is sent
834 to application (otherwise application doesn't know that it is for
835 channel (library gets it from packet's Destination ID)).
837 * Added silc_client_remove_from_channels into client library to
838 remove a client from all channels it has joined to. Used when
839 received SIGNOFF notify from server. Added also new function
840 silc_client_replace_from_channels to replace old ID entry with
841 new ID entry on all channels. Used when received NICK_CHANGE
844 * Fixed ID Cache list handling in silc_idlist_get_client in
845 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
846 to get (or query) client by ID.
850 * Added connection authentication status message defined by the
851 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
852 support for these into the code in client and server side.
854 * Added generic function silc_client_send_command to send any command
855 with variable argument list. Application should use this function
856 to send commands if the command functions provided by the library
857 does not suite for the application's user interface needs.
859 * Added new `failure' client operation. Application is notified about
860 received failure packet if client is executing a protocol. In this
861 case the protocol's execution has failed.
863 * Added SKE's end notify to send the SKE_SUCCESS notify message that
864 is required by the protocol.
866 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
867 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
870 * Added status flag to SilcSKE object to indicate realtime status
873 * Application receives now exactly same command reply arguments as
874 the library receives from server. However, if ID is received the
875 corresponding ID entry is returned to the application (eg. Client
876 ID is mapped to correct SilcClientEntry entry and that is returned).
877 Changed command_reply client operation due to this change.
879 * Changed all ID's in commands and in command replys as ID Payloads.
880 Change affected both client and server side codes.
882 All ID's sent in SILC network (with execption of ID's in SILC
883 Packet header) are sent in ID Payload to support variable length
886 * Server now notifies nick changes and notifies all clients on
887 the channels about the new nickname (about the new Client ID,
890 * Implemented CMODE command to change channel modes. Supports all
891 channel modes defined by the protocol specs except ban and invite
892 lists. (Also, private channel key mode is supported but support for
893 setting private channel key in client is missing, thus, this mode
894 has no effect on client side (except that server requires that the
895 client uses private channel key and normal channel traffic does not
898 Also, invite mode works per se, but INVITE command does not work
899 yet correctly, so you can set channel as invite only channel but
900 inviting clients to the channel does not work (it is yet to be
901 thought what's the best way to do it).
903 * Added new command SILC_COMMAND_CUMODE to change user mode on the
904 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
905 Implemented CUMODE command to change user's mode on the channel.
906 Supports all modes defined by the protocol specs.
908 * Added NAMES command reply to return users modes on the channel.
910 * Removed unnecessary and slow ciphers from lib/silccrypt.
912 * Set SO_KEEPALIVE option to connection sockets by default.
914 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
916 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
917 redefined the Notify Payload into protocol specs.
919 * Added silc_id_payload_parse_id to get ID directly from raw
922 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
924 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
925 accept searching by Client ID as well.
927 * Added support for LEAVE and SIGNOFF notify types in client library.
929 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
930 to parse ID Payload from raw data.
932 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * Added flags parameter into silc_ske_assemble_security_properties
935 function in lib/silcske/silcske.[ch].
937 * Changed notify client operation to fit better for notify messages
938 sent by server. The notify payload received from server is now
939 passed to the application (after parsing it to SilcNotifyPayload).
940 It is application's responsibility to retrieve the arguments
941 from the payload and show the message the way it wants. The message
942 sent by server is implementation specific.
944 * Changed public keys to comply with the protocol specification.
945 Old public keys are not supported anymore and are not compatible.
947 * Removed nickname from Channel Payload as the latest draft removed
948 it. The client must resolve the nickname from the NAMES command
949 reply received when it joined the channel.
951 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
953 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Fixed some errors in protocol specification drafts.
957 * Created lib/silccore/silcnotify.c to implement Notify Payload
958 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
959 generic payloads described by protocol specifications. The file
960 includes implementations for ID Payload and Argument Payload.
962 * Changed Command Payload implementation to use the new Argument
963 Payload. Changed command_xxxx_payload to command_payload_xxxx
964 to comply with SILC coding conventions.
966 * Added suppport for Argument Payload handling in Notify Payload
967 implementation as protocol requires it. Added the new support
968 into server and client lib as well.
970 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
972 * Added support for multiple nicknames on same channel. [n] is
973 added locally to the nickname if there are more than one same
974 nicknames on the channel.
976 * Server now sends all nicknames that matched WHOIS request.
977 Client also shows the list received from server.
979 * Added TOPIC command to client side. User can now set and show
980 current topic on channel.
982 * Added MOTD command to client and server. Also, server sends the
983 motd when client connects to the server.
985 * Changed version strings to comply ISO 8601.
987 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
989 * Fixed protocol error handling in client library. It should now
990 cope even if the SKE fails for some reason.
992 * Made new protocol specification drafts for submitting to IETF.
994 * Implemented TOPIC command to server in silcd/command.c.
996 * Added two new notify types into lib/silccore/silcnotify.h:
997 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
998 notify nickname change and topic setting/change on a channel.
1000 * API change of command_reply operation in client library. The
1001 application gets now the status type received from server as well.
1003 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1005 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1007 * Cras fixed and optimized the packet handling even further and
1008 it should work now. Minor change to the prototype of function
1009 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1011 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1013 * Added new function into lib/silcutil/silcschedule.[ch]:
1014 silc_schedule_with_fd to select() a specified fd. The function
1015 returns after timeout expires or data arrives or goes. The
1016 function is used by packet routines to wait that all data is
1017 received from network.
1019 * Fixed data reading from network in lib/silccore/silcpacket.c.
1020 The code now assures that all data is read from the fd and then
1021 continues packet processing. This was a bug fix since the code
1022 used to drop some data in some circumstances.
1024 * Added new function into lib/silcclient/client.[ch]:
1025 silc_client_start_key_exchange to start key exchange after
1026 connection has been established to server. The code internally
1027 now uses this funtion but its main purpose was to provide it
1028 for applications that perform their own connecting. After
1029 application has created a connection it merely calls this
1030 function to start the key exchange between client and server.
1031 The library takes care of everything else after that.
1033 Updated also lib/silcclient/README to explain the usage of
1036 * Do not send to application information that connection has
1037 been established. Application gets notified it by connect
1040 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Applied cras's patch to add silc_schedule_one function. The
1043 function runs scheduler once and returns.
1045 * Fixed the scheduler after cras messed it up. The timeout
1046 handling works now as it's supposed to work.
1048 * Added into lib/silccore/ silcnotify.h to include notify
1049 message types support. Changed silc_server_send_notify*
1050 functions, in server.[ch], to support those new notify types.
1051 Added the support for the notify types into client library,
1052 as well. Added new notify client operation into ops.h in
1055 * Changed silc_server_packet_send_to_channel to send normal
1056 packets instead of just channel message packets. The function
1057 is now used to send the notify packets to channels. It is not
1058 used to send channel message packets anymore, as server never
1061 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1062 va_arg()s as it seems to require it nowadays. I guess, if SILC
1063 is compiled with older va_arg() the new code should work anyway.
1065 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Splitted core library. Core library (lib/silccore) includes
1068 now only SILC protocol specific core (and common) components.
1069 Created new utility library (lib/silcutil) that includes more
1070 generic purpose stuff. The stuff for util library was taken
1071 from the old core library. This was minor and easy split.
1073 * Created SILC Client Library (lib/silcclient) that includes
1074 implementation of the SILC client without user interface. This
1075 was major move from silc/ directory. The code has been changed
1076 so that it is transparent towards the user interface. The
1077 silc/ directory includes now the same user interface as before
1078 and it uses the new client library. Read lib/silcclient/README.
1079 Basicly, the client library performs everything else related
1080 to SILC except user interface handling. Also, configuration
1081 files are considered to be part of user interface and library
1082 does not handle them.
1084 This change also changed a lot of structures, function naming etc.
1085 Most important change was that SilcClientWindow object was
1086 renamed to SilcClientConnection in the client library. Created
1087 also new file lib/silcclient/ops.h. Also added new files
1088 silc/local_command.[ch] and silc/client_ops.[ch].
1090 All these changes were made to make it easier for user interface
1091 designers to create what ever user interface for the SILC client
1094 It is also expected that the server will be moved to lib
1095 directory as well and SILC Server Library will be created;
1096 sometimes in the future.
1098 * Removed Local commands from lib/silccore/silccommand.h as
1099 they are application specific and new client library does not
1100 handle any of those anymore.
1102 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1103 old client implementation in silc/.
1105 * Added support for callback functions in SILC_LOG_* macros.
1106 Application can now set its own callbacks that will be called
1107 instead of using the default functions that will always print
1108 the debug messages to stderr (or stdout). Also, debugging can
1109 now be disabled by setting silc_debug to FALSE and re-enabled by
1110 setting it to TRUE. Note, that logging will still work even
1111 if debugging is disabled.
1113 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1114 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1115 silc_log_reset_debug_callbacks.
1117 * To enable debugging in silc client one must give now -d
1118 option on command line.
1120 * Changed silc_schedule_init to automatically allocate task queues
1121 if they are not allocated before calling it.
1123 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1125 * Added GMP 3.1 into math library.
1127 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1130 a channel in SILC network. The packet is used by servers and
1131 routers to notify other routers that user has left a channel.
1132 This little feature was missing until now. Added the feature
1133 to protocol specification as well.
1135 Added functions: silc_server_send_remove_channel_user and
1136 silc_server_remove_channel_user into server.[ch].
1138 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1139 lib/silccore/silcpacket.h. However, they are not implemented
1142 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Fixed joining to a channel and sending channel messages
1145 between server and router. The channel message sending should
1146 now work inside a cell.
1148 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * Fixed the private message sending between server and router.
1151 The private message sending should now work inside a cell.
1153 * Added silc_server_replace_id into server.[ch] to replace
1154 existing ID in the SILC network.
1156 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1157 and silc_idlist_replace_server_id into idlist.[ch] in server.
1159 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Fixed the server to server connections. Server can again now
1162 connect to router. Router to router connections probably does
1165 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Added dynamic protocol registering support. Now protocols can
1168 registered and unregistered on the fly. Patch by cras.
1170 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Added lib/contrib directory to hold routines that some platforms
1173 don't have but are needed by SILC.
1175 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1176 into lin/contrib to provide getopt() and getopt_long() for
1177 those who don't have it.
1179 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Added AWAY command to client. When away message is set and
1182 client receives a private message packet the client automatically
1183 replies to the sender with the away message.
1185 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1186 bug seemed to be the cause of recent problems when compiling
1189 * Added version detection support to SKE protocol specification
1190 and added the new changes to the SKE implementation as well.
1191 There were other minor changes in the SKE protocol as well.
1193 Many changes in lib/silcske/silcske.[ch] and in
1194 lib/silcske/payload.[ch].
1196 * Added ^U functionality, clear input line. Patch from cras.
1198 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1200 * Mainly small bugfixes on core library. Fixed some debugging
1201 logging and buffer overflow in silclog.c.
1203 * Updated config.sub and config.guess on the distribution tree.
1205 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Added command lagging support in server. Client may execute
1208 commands now only once in two seconds.
1210 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1212 * Optimized packet reception. MAC computation and checking is now
1213 also more optimized. A lot previously duplicated code is now
1214 used as generic by both client and server.
1216 * Fixed key pair generation in clientutil.c
1218 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Added into lib/silccore/silcbufutil.[ch] new function;
1221 silc_buffer_realloc.
1223 * Moved generic packet sending/encryption functions to
1224 lib/silccore/silcpacket.[ch] from client and server. Some
1225 rewriting of the functions.
1227 * Moved all generic packet reception/decryption functions to
1228 lib/silccore/silcpacket.[ch] from client and server. The
1229 packet processing is now much cleaner in both client and server.
1230 These were major changes in both client and server.
1232 * Created many common functions in server to do packet sending.
1233 Previously code were duplicated a lot, this has been removed
1236 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Rewrote major parts of the ID cache system. Don't know
1239 whether it is better now or not but at least the API is more
1242 * Major rewrite on ID cache stuff on client because of the ID
1243 cache API changes. Added idlist.c to client.
1245 * Also major rewrite on ID cache stuff on server as well.
1246 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1247 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1248 in hand, instead they are all put into the ID cache system now.
1249 All server_idlist_* routines uses ID cache now instead of
1250 traversing its own lists (those lists does not exist anymore).
1251 SilcIDList though still exists. Also, SilcXXXEntry's are
1254 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1256 * Finally made the SKE implementation compliant to the protocol
1257 specification. All mp integers are now binary encoded as
1258 opposed being HEX encoded.
1260 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1263 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1264 functions: silc_[encode/decode]_pem. Also added function
1265 silc_encode_pem_file to PEM encode with newlines ('\n') for
1268 * SILC public keys are now encoded either PEM or binary. Same
1269 option is for private keys as well. By default private keys
1270 are binary encoded and public keys PEM encoded. Silly HEX
1271 encoding were removed.
1273 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1274 function to create fingerprints.
1276 * Fixed a bug in SHA1; does not change the original data anymore.
1278 * Partly implemented INFO command on client and server side.
1279 Fixed CLEAR command. Changes to SERVER command; show current
1280 server(s) when giving command without arguments. Added
1281 VERSION command to client.
1283 * Added check to server that unregistered connections cannot
1284 execute commands (unless it is specificly allowed).
1286 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1288 * Fixed screen refresh.
1290 * Fixed channel joining bug from client. On some circumstances
1291 client tried to join to a channel it had already joined.
1293 * Added public key verification process into client's protocol.c.
1294 The client now verifies the public key from user and saves
1295 it into ~./silc/serverkeys/ directory.
1297 Added into: clientutil.[ch]: silc_client_verify_server_key.
1299 * Changed SKE protocol's silc_ske_initiator_finish function
1300 to accept callback function that verifies the received public
1301 key. Removed old silc_ske_verify_public_key function.
1303 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1306 silc_pkcs_private_key[_data]_set.
1308 * Made the password and public authentication more cleaner in
1309 server's protocol.c.
1311 * Removed historic and obsolete protocol `channel_auth' from
1312 both client and server.
1314 * Removed wrong way of sending command status messages from
1315 server to client in server's command.c. The old way violated
1316 protocol specification.
1318 Changes to silccore/silccommand.[ch]: removed
1319 silc_command_encode_status_payload -> not needed anymore,
1320 changed silc_command_encode_payload_va to accept extra
1321 argument on variable argument list. The argument type must
1322 now be provided to the function. Also, added new function:
1323 silc_command_encode_reply_payload_va which is same as
1324 normal command_encode_payload_va except command status type
1325 is provided as extra argument.
1327 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Added ~./silc directory handling. The directory includes the
1330 public and private keys for the client.
1332 Added silc_client_check_silc_dir, silc_client_create_identifier
1333 and silc_client_load_keys.
1335 * Implemented SILC protocol compliant public key. Added public
1336 and private key saving to and loading from files.
1338 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1339 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1340 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1341 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1342 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1344 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1345 silc_pkcs_load_[public/private]_key.
1347 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Added silc_server_get_route (route.[ch]) to get connection
1350 data for the fastest route for given ID.
1352 * Implemented INVITE command on client and server. The command
1353 were re-defined in the SILC Protocol Specification and the
1354 implementation now complies with the specification.
1356 * Implemented PING command on client and server.
1358 * Implemented NAMES command on client and server. The server side
1359 supports currently only normal server not router server yet.
1360 Some changes to NAMES definition in SILC protocol specification.
1362 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1364 * Implemented LEAVE command on client and server.
1366 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1367 again. This change was made to the protocol as well. Server
1368 should not violate the protocol specification anymore.
1370 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1372 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1373 was tested. SOCKS4 was not but should work anyway.
