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