3 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Added TRQ (efficient deque and list library) into lib/trq. This is
13 a very good list library that is currently used in the SILC. Defined
14 SilcList API over the library because I didn't like the API very
15 much. See lib/trq/silclist.h for the API and examples of how to
16 use the API. Fixed various places in the code to use the new
17 SilcList API. The SilcList is meant for lists that has a structure
18 already defined as a list. It is not suitable to add just some
19 context to the list (in TRQ, the context is the list actually).
21 So, I defined SilcDList that can be used for the purpose where
22 predefined list structure does not exit. This can be used as
23 such list. Now some context just can be added to the SilcDList.
24 Currently this list is not used in the SILC just yet, though there
25 are a lot places where this can replace dynamically allocated
26 tables and I will fix these places, later, to use SilcDList.
27 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
28 and use TRQ internally).
30 Also fixed some annoying warning messages that the original TRQ
31 code generated. Also minor changes to TRQ's Makefile.in.
33 * Added support for querying by Client ID to both WHOIS and
34 IDENTIFY commands into server, as required by the protocol.
36 * Removed method function pointers from SilcBuffer structure. They
37 weren't used to anything and just increased the context size for
38 no good reason. This change also made silc_buffer_alloc and
39 silc_buffer_free functions inline functions.
41 * Disabled command flooding detection support until it's fixed so
42 that it accepts commands in but does not execute them more than once
45 * Added silc_net_localhost(), to return local hostname, into
46 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
47 that must be initialized before calling silc_client_init.
49 * Added new function: silc_server_send_notify_on_channels to send
50 notify messages to all channels client has joined. It is assured
51 that the message is sent only once per client.
53 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
54 lib/silcutil/silcutil.[ch] as silc_format function. The new
55 function is generic and is used by server as well, not only by
58 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
59 the provided version string was not acceptable. Added new function:
60 silc_ske_check_version into lib/silcske/silcske.h. The function
61 must be implemented by the application (client or server) and it
62 does not reside in the SKE library. The function checks the version
63 string remote end sent.
65 * Added back pointers (to opaque context and to SilcSocketConnection)
66 into SilcPacketContext structure into lib/silccore/silcpacket.h.
68 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
69 duplicate packet context structure.
71 * Changed `notify' client operation to send same arguments as client
72 receives from server except for ID's. ID's are mapped to correct
73 ID entry and that is returned. Also, if channel entry is not sent
74 by server but the notify is for channel the channel entry is sent
75 to application (otherwise application doesn't know that it is for
76 channel (library gets it from packet's Destination ID)).
78 * Added silc_client_remove_from_channels into client library to
79 remove a client from all channels it has joined to. Used when
80 received SIGNOFF notify from server. Added also new function
81 silc_client_replace_from_channels to replace old ID entry with
82 new ID entry on all channels. Used when received NICK_CHANGE
85 * Fixed ID Cache list handling in silc_idlist_get_client in
86 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
87 to get (or query) client by ID.
91 * Added connection authentication status message defined by the
92 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
93 support for these into the code in client and server side.
95 * Added generic function silc_client_send_command to send any command
96 with variable argument list. Application should use this function
97 to send commands if the command functions provided by the library
98 does not suite for the application's user interface needs.
100 * Added new `failure' client operation. Application is notified about
101 received failure packet if client is executing a protocol. In this
102 case the protocol's execution has failed.
104 * Added SKE's end notify to send the SKE_SUCCESS notify message that
105 is required by the protocol.
107 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
108 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
111 * Added status flag to SilcSKE object to indicate realtime status
114 * Application receives now exactly same command reply arguments as
115 the library receives from server. However, if ID is received the
116 corresponding ID entry is returned to the application (eg. Client
117 ID is mapped to correct SilcClientEntry entry and that is returned).
118 Changed command_reply client operation due to this change.
120 * Changed all ID's in commands and in command replys as ID Payloads.
121 Change affected both client and server side codes.
123 All ID's sent in SILC network (with execption of ID's in SILC
124 Packet header) are sent in ID Payload to support variable length
127 * Server now notifies nick changes and notifies all clients on
128 the channels about the new nickname (about the new Client ID,
131 * Implemented CMODE command to change channel modes. Supports all
132 channel modes defined by the protocol specs except ban and invite
133 lists. (Also, private channel key mode is supported but support for
134 setting private channel key in client is missing, thus, this mode
135 has no effect on client side (except that server requires that the
136 client uses private channel key and normal channel traffic does not
139 Also, invite mode works per se, but INVITE command does not work
140 yet correctly, so you can set channel as invite only channel but
141 inviting clients to the channel does not work (it is yet to be
142 thought what's the best way to do it).
144 * Added new command SILC_COMMAND_CUMODE to change user mode on the
145 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
146 Implemented CUMODE command to change user's mode on the channel.
147 Supports all modes defined by the protocol specs.
149 * Added NAMES command reply to return users modes on the channel.
151 * Removed unnecessary and slow ciphers from lib/silccrypt.
153 * Set SO_KEEPALIVE option to connection sockets by default.
155 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
157 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
158 redefined the Notify Payload into protocol specs.
160 * Added silc_id_payload_parse_id to get ID directly from raw
163 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
166 accept searching by Client ID as well.
168 * Added support for LEAVE and SIGNOFF notify types in client library.
170 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
171 to parse ID Payload from raw data.
173 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
175 * Added flags parameter into silc_ske_assemble_security_properties
176 function in lib/silcske/silcske.[ch].
178 * Changed notify client operation to fit better for notify messages
179 sent by server. The notify payload received from server is now
180 passed to the application (after parsing it to SilcNotifyPayload).
181 It is application's responsibility to retrieve the arguments
182 from the payload and show the message the way it wants. The message
183 sent by server is implementation specific.
185 * Changed public keys to comply with the protocol specification.
186 Old public keys are not supported anymore and are not compatible.
188 * Removed nickname from Channel Payload as the latest draft removed
189 it. The client must resolve the nickname from the NAMES command
190 reply received when it joined the channel.
192 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
194 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Fixed some errors in protocol specification drafts.
198 * Created lib/silccore/silcnotify.c to implement Notify Payload
199 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
200 generic payloads described by protocol specifications. The file
201 includes implementations for ID Payload and Argument Payload.
203 * Changed Command Payload implementation to use the new Argument
204 Payload. Changed command_xxxx_payload to command_payload_xxxx
205 to comply with SILC coding conventions.
207 * Added suppport for Argument Payload handling in Notify Payload
208 implementation as protocol requires it. Added the new support
209 into server and client lib as well.
211 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
213 * Added support for multiple nicknames on same channel. [n] is
214 added locally to the nickname if there are more than one same
215 nicknames on the channel.
217 * Server now sends all nicknames that matched WHOIS request.
218 Client also shows the list received from server.
220 * Added TOPIC command to client side. User can now set and show
221 current topic on channel.
223 * Added MOTD command to client and server. Also, server sends the
224 motd when client connects to the server.
226 * Changed version strings to comply ISO 8601.
228 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Fixed protocol error handling in client library. It should now
231 cope even if the SKE fails for some reason.
233 * Made new protocol specification drafts for submitting to IETF.
235 * Implemented TOPIC command to server in silcd/command.c.
237 * Added two new notify types into lib/silccore/silcnotify.h:
238 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
239 notify nickname change and topic setting/change on a channel.
241 * API change of command_reply operation in client library. The
242 application gets now the status type received from server as well.
244 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
246 * Removed the function just added to lib/silcutil/silcschedule.[ch].
248 * Cras fixed and optimized the packet handling even further and
249 it should work now. Minor change to the prototype of function
250 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
252 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
254 * Added new function into lib/silcutil/silcschedule.[ch]:
255 silc_schedule_with_fd to select() a specified fd. The function
256 returns after timeout expires or data arrives or goes. The
257 function is used by packet routines to wait that all data is
258 received from network.
260 * Fixed data reading from network in lib/silccore/silcpacket.c.
261 The code now assures that all data is read from the fd and then
262 continues packet processing. This was a bug fix since the code
263 used to drop some data in some circumstances.
265 * Added new function into lib/silcclient/client.[ch]:
266 silc_client_start_key_exchange to start key exchange after
267 connection has been established to server. The code internally
268 now uses this funtion but its main purpose was to provide it
269 for applications that perform their own connecting. After
270 application has created a connection it merely calls this
271 function to start the key exchange between client and server.
272 The library takes care of everything else after that.
274 Updated also lib/silcclient/README to explain the usage of
277 * Do not send to application information that connection has
278 been established. Application gets notified it by connect
281 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Applied cras's patch to add silc_schedule_one function. The
284 function runs scheduler once and returns.
286 * Fixed the scheduler after cras messed it up. The timeout
287 handling works now as it's supposed to work.
289 * Added into lib/silccore/ silcnotify.h to include notify
290 message types support. Changed silc_server_send_notify*
291 functions, in server.[ch], to support those new notify types.
292 Added the support for the notify types into client library,
293 as well. Added new notify client operation into ops.h in
296 * Changed silc_server_packet_send_to_channel to send normal
297 packets instead of just channel message packets. The function
298 is now used to send the notify packets to channels. It is not
299 used to send channel message packets anymore, as server never
302 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
303 va_arg()s as it seems to require it nowadays. I guess, if SILC
304 is compiled with older va_arg() the new code should work anyway.
306 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * Splitted core library. Core library (lib/silccore) includes
309 now only SILC protocol specific core (and common) components.
310 Created new utility library (lib/silcutil) that includes more
311 generic purpose stuff. The stuff for util library was taken
312 from the old core library. This was minor and easy split.
314 * Created SILC Client Library (lib/silcclient) that includes
315 implementation of the SILC client without user interface. This
316 was major move from silc/ directory. The code has been changed
317 so that it is transparent towards the user interface. The
318 silc/ directory includes now the same user interface as before
319 and it uses the new client library. Read lib/silcclient/README.
320 Basicly, the client library performs everything else related
321 to SILC except user interface handling. Also, configuration
322 files are considered to be part of user interface and library
323 does not handle them.
325 This change also changed a lot of structures, function naming etc.
326 Most important change was that SilcClientWindow object was
327 renamed to SilcClientConnection in the client library. Created
328 also new file lib/silcclient/ops.h. Also added new files
329 silc/local_command.[ch] and silc/client_ops.[ch].
331 All these changes were made to make it easier for user interface
332 designers to create what ever user interface for the SILC client
335 It is also expected that the server will be moved to lib
336 directory as well and SILC Server Library will be created;
337 sometimes in the future.
339 * Removed Local commands from lib/silccore/silccommand.h as
340 they are application specific and new client library does not
341 handle any of those anymore.
343 * Several functions moved to lib/silcutil/silcutilc.[ch] from
344 old client implementation in silc/.
346 * Added support for callback functions in SILC_LOG_* macros.
347 Application can now set its own callbacks that will be called
348 instead of using the default functions that will always print
349 the debug messages to stderr (or stdout). Also, debugging can
350 now be disabled by setting silc_debug to FALSE and re-enabled by
351 setting it to TRUE. Note, that logging will still work even
352 if debugging is disabled.
354 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
355 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
356 silc_log_reset_debug_callbacks.
358 * To enable debugging in silc client one must give now -d
359 option on command line.
361 * Changed silc_schedule_init to automatically allocate task queues
362 if they are not allocated before calling it.
364 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Added GMP 3.1 into math library.
368 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
371 a channel in SILC network. The packet is used by servers and
372 routers to notify other routers that user has left a channel.
373 This little feature was missing until now. Added the feature
374 to protocol specification as well.
376 Added functions: silc_server_send_remove_channel_user and
377 silc_server_remove_channel_user into server.[ch].
379 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
380 lib/silccore/silcpacket.h. However, they are not implemented
383 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Fixed joining to a channel and sending channel messages
386 between server and router. The channel message sending should
387 now work inside a cell.
389 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
391 * Fixed the private message sending between server and router.
392 The private message sending should now work inside a cell.
394 * Added silc_server_replace_id into server.[ch] to replace
395 existing ID in the SILC network.
397 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
398 and silc_idlist_replace_server_id into idlist.[ch] in server.
400 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Fixed the server to server connections. Server can again now
403 connect to router. Router to router connections probably does
406 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
408 * Added dynamic protocol registering support. Now protocols can
409 registered and unregistered on the fly. Patch by cras.
411 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
413 * Added lib/contrib directory to hold routines that some platforms
414 don't have but are needed by SILC.
416 * Added getopt.c, getopt1.c and getopt.h from GNU C library
417 into lin/contrib to provide getopt() and getopt_long() for
418 those who don't have it.
420 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
422 * Added AWAY command to client. When away message is set and
423 client receives a private message packet the client automatically
424 replies to the sender with the away message.
426 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
427 bug seemed to be the cause of recent problems when compiling
430 * Added version detection support to SKE protocol specification
431 and added the new changes to the SKE implementation as well.
432 There were other minor changes in the SKE protocol as well.
434 Many changes in lib/silcske/silcske.[ch] and in
435 lib/silcske/payload.[ch].
437 * Added ^U functionality, clear input line. Patch from cras.
439 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Mainly small bugfixes on core library. Fixed some debugging
442 logging and buffer overflow in silclog.c.
444 * Updated config.sub and config.guess on the distribution tree.
446 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
448 * Added command lagging support in server. Client may execute
449 commands now only once in two seconds.
451 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Optimized packet reception. MAC computation and checking is now
454 also more optimized. A lot previously duplicated code is now
455 used as generic by both client and server.
457 * Fixed key pair generation in clientutil.c
459 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * Added into lib/silccore/silcbufutil.[ch] new function;
464 * Moved generic packet sending/encryption functions to
465 lib/silccore/silcpacket.[ch] from client and server. Some
466 rewriting of the functions.
468 * Moved all generic packet reception/decryption functions to
469 lib/silccore/silcpacket.[ch] from client and server. The
470 packet processing is now much cleaner in both client and server.
471 These were major changes in both client and server.
473 * Created many common functions in server to do packet sending.
474 Previously code were duplicated a lot, this has been removed
477 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Rewrote major parts of the ID cache system. Don't know
480 whether it is better now or not but at least the API is more
483 * Major rewrite on ID cache stuff on client because of the ID
484 cache API changes. Added idlist.c to client.
486 * Also major rewrite on ID cache stuff on server as well.
487 Major rewrite of idlist.[ch]. SilcXXXList's are now named
488 SilcXXXEntry's. We won't keep anymore idlist specific pointers
489 in hand, instead they are all put into the ID cache system now.
490 All server_idlist_* routines uses ID cache now instead of
491 traversing its own lists (those lists does not exist anymore).
492 SilcIDList though still exists. Also, SilcXXXEntry's are
495 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
497 * Finally made the SKE implementation compliant to the protocol
498 specification. All mp integers are now binary encoded as
499 opposed being HEX encoded.
501 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
504 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
505 functions: silc_[encode/decode]_pem. Also added function
506 silc_encode_pem_file to PEM encode with newlines ('\n') for
509 * SILC public keys are now encoded either PEM or binary. Same
510 option is for private keys as well. By default private keys
511 are binary encoded and public keys PEM encoded. Silly HEX
512 encoding were removed.
514 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
515 function to create fingerprints.
517 * Fixed a bug in SHA1; does not change the original data anymore.
519 * Partly implemented INFO command on client and server side.
520 Fixed CLEAR command. Changes to SERVER command; show current
521 server(s) when giving command without arguments. Added
522 VERSION command to client.
524 * Added check to server that unregistered connections cannot
525 execute commands (unless it is specificly allowed).
527 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
529 * Fixed screen refresh.
531 * Fixed channel joining bug from client. On some circumstances
532 client tried to join to a channel it had already joined.
534 * Added public key verification process into client's protocol.c.
535 The client now verifies the public key from user and saves
536 it into ~./silc/serverkeys/ directory.
538 Added into: clientutil.[ch]: silc_client_verify_server_key.
540 * Changed SKE protocol's silc_ske_initiator_finish function
541 to accept callback function that verifies the received public
542 key. Removed old silc_ske_verify_public_key function.
544 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
546 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
547 silc_pkcs_private_key[_data]_set.
549 * Made the password and public authentication more cleaner in
552 * Removed historic and obsolete protocol `channel_auth' from
553 both client and server.
555 * Removed wrong way of sending command status messages from
556 server to client in server's command.c. The old way violated
557 protocol specification.
559 Changes to silccore/silccommand.[ch]: removed
560 silc_command_encode_status_payload -> not needed anymore,
561 changed silc_command_encode_payload_va to accept extra
562 argument on variable argument list. The argument type must
563 now be provided to the function. Also, added new function:
564 silc_command_encode_reply_payload_va which is same as
565 normal command_encode_payload_va except command status type
566 is provided as extra argument.
568 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Added ~./silc directory handling. The directory includes the
571 public and private keys for the client.
573 Added silc_client_check_silc_dir, silc_client_create_identifier
574 and silc_client_load_keys.
576 * Implemented SILC protocol compliant public key. Added public
577 and private key saving to and loading from files.
579 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
580 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
