3 * Renamed configure.in to configure.in.pre and made ./prepare
4 script to automatically add correct version string to
5 configure.in which it creates from configure.in.pre.
7 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9 * NAMES command reply now shows users mode with the nickname when
12 * Moved silc_client_ch[u]mode[_char] functions from
13 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
14 place sucks, they are utility functions and should be in some
17 * Fixed some unsigned int's to unsigned short's. Patch by cras.
19 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
22 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
26 * Added TRQ (efficient deque and list library) into lib/trq. This is
27 a very good list library that is currently used in the SILC. Defined
28 SilcList API over the library because I didn't like the API very
29 much. See lib/trq/silclist.h for the API and examples of how to
30 use the API. Fixed various places in the code to use the new
31 SilcList API. The SilcList is meant for lists that has a structure
32 already defined as a list. It is not suitable to add just some
33 context to the list (in TRQ, the context is the list actually).
35 So, I defined SilcDList that can be used for the purpose where
36 predefined list structure does not exit. This can be used as
37 such list. Now some context just can be added to the SilcDList.
38 Currently this list is not used in the SILC just yet, though there
39 are a lot places where this can replace dynamically allocated
40 tables and I will fix these places, later, to use SilcDList.
41 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
42 and use TRQ internally).
44 Also fixed some annoying warning messages that the original TRQ
45 code generated. Also minor changes to TRQ's Makefile.in.
47 * Added support for querying by Client ID to both WHOIS and
48 IDENTIFY commands into server, as required by the protocol.
50 * Removed method function pointers from SilcBuffer structure. They
51 weren't used to anything and just increased the context size for
52 no good reason. This change also made silc_buffer_alloc and
53 silc_buffer_free functions inline functions.
55 * Disabled command flooding detection support until it's fixed so
56 that it accepts commands in but does not execute them more than once
59 * Added silc_net_localhost(), to return local hostname, into
60 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
61 that must be initialized before calling silc_client_init.
63 * Added new function: silc_server_send_notify_on_channels to send
64 notify messages to all channels client has joined. It is assured
65 that the message is sent only once per client.
67 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
68 lib/silcutil/silcutil.[ch] as silc_format function. The new
69 function is generic and is used by server as well, not only by
72 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
73 the provided version string was not acceptable. Added new function:
74 silc_ske_check_version into lib/silcske/silcske.h. The function
75 must be implemented by the application (client or server) and it
76 does not reside in the SKE library. The function checks the version
77 string remote end sent.
79 * Added back pointers (to opaque context and to SilcSocketConnection)
80 into SilcPacketContext structure into lib/silccore/silcpacket.h.
82 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
83 duplicate packet context structure.
85 * Changed `notify' client operation to send same arguments as client
86 receives from server except for ID's. ID's are mapped to correct
87 ID entry and that is returned. Also, if channel entry is not sent
88 by server but the notify is for channel the channel entry is sent
89 to application (otherwise application doesn't know that it is for
90 channel (library gets it from packet's Destination ID)).
92 * Added silc_client_remove_from_channels into client library to
93 remove a client from all channels it has joined to. Used when
94 received SIGNOFF notify from server. Added also new function
95 silc_client_replace_from_channels to replace old ID entry with
96 new ID entry on all channels. Used when received NICK_CHANGE
99 * Fixed ID Cache list handling in silc_idlist_get_client in
100 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
101 to get (or query) client by ID.
105 * Added connection authentication status message defined by the
106 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
107 support for these into the code in client and server side.
109 * Added generic function silc_client_send_command to send any command
110 with variable argument list. Application should use this function
111 to send commands if the command functions provided by the library
112 does not suite for the application's user interface needs.
114 * Added new `failure' client operation. Application is notified about
115 received failure packet if client is executing a protocol. In this
116 case the protocol's execution has failed.
118 * Added SKE's end notify to send the SKE_SUCCESS notify message that
119 is required by the protocol.
121 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
122 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
125 * Added status flag to SilcSKE object to indicate realtime status
128 * Application receives now exactly same command reply arguments as
129 the library receives from server. However, if ID is received the
130 corresponding ID entry is returned to the application (eg. Client
131 ID is mapped to correct SilcClientEntry entry and that is returned).
132 Changed command_reply client operation due to this change.
134 * Changed all ID's in commands and in command replys as ID Payloads.
135 Change affected both client and server side codes.
137 All ID's sent in SILC network (with execption of ID's in SILC
138 Packet header) are sent in ID Payload to support variable length
141 * Server now notifies nick changes and notifies all clients on
142 the channels about the new nickname (about the new Client ID,
145 * Implemented CMODE command to change channel modes. Supports all
146 channel modes defined by the protocol specs except ban and invite
147 lists. (Also, private channel key mode is supported but support for
148 setting private channel key in client is missing, thus, this mode
149 has no effect on client side (except that server requires that the
150 client uses private channel key and normal channel traffic does not
153 Also, invite mode works per se, but INVITE command does not work
154 yet correctly, so you can set channel as invite only channel but
155 inviting clients to the channel does not work (it is yet to be
156 thought what's the best way to do it).
158 * Added new command SILC_COMMAND_CUMODE to change user mode on the
159 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
160 Implemented CUMODE command to change user's mode on the channel.
161 Supports all modes defined by the protocol specs.
163 * Added NAMES command reply to return users modes on the channel.
165 * Removed unnecessary and slow ciphers from lib/silccrypt.
167 * Set SO_KEEPALIVE option to connection sockets by default.
169 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
171 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
172 redefined the Notify Payload into protocol specs.
174 * Added silc_id_payload_parse_id to get ID directly from raw
177 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
179 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
180 accept searching by Client ID as well.
182 * Added support for LEAVE and SIGNOFF notify types in client library.
184 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
185 to parse ID Payload from raw data.
187 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Added flags parameter into silc_ske_assemble_security_properties
190 function in lib/silcske/silcske.[ch].
192 * Changed notify client operation to fit better for notify messages
193 sent by server. The notify payload received from server is now
194 passed to the application (after parsing it to SilcNotifyPayload).
195 It is application's responsibility to retrieve the arguments
196 from the payload and show the message the way it wants. The message
197 sent by server is implementation specific.
199 * Changed public keys to comply with the protocol specification.
200 Old public keys are not supported anymore and are not compatible.
202 * Removed nickname from Channel Payload as the latest draft removed
203 it. The client must resolve the nickname from the NAMES command
204 reply received when it joined the channel.
206 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
208 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Fixed some errors in protocol specification drafts.
212 * Created lib/silccore/silcnotify.c to implement Notify Payload
213 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
214 generic payloads described by protocol specifications. The file
215 includes implementations for ID Payload and Argument Payload.
217 * Changed Command Payload implementation to use the new Argument
218 Payload. Changed command_xxxx_payload to command_payload_xxxx
219 to comply with SILC coding conventions.
221 * Added suppport for Argument Payload handling in Notify Payload
222 implementation as protocol requires it. Added the new support
223 into server and client lib as well.
225 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
227 * Added support for multiple nicknames on same channel. [n] is
228 added locally to the nickname if there are more than one same
229 nicknames on the channel.
231 * Server now sends all nicknames that matched WHOIS request.
232 Client also shows the list received from server.
234 * Added TOPIC command to client side. User can now set and show
235 current topic on channel.
237 * Added MOTD command to client and server. Also, server sends the
238 motd when client connects to the server.
240 * Changed version strings to comply ISO 8601.
242 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Fixed protocol error handling in client library. It should now
245 cope even if the SKE fails for some reason.
247 * Made new protocol specification drafts for submitting to IETF.
249 * Implemented TOPIC command to server in silcd/command.c.
251 * Added two new notify types into lib/silccore/silcnotify.h:
252 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
253 notify nickname change and topic setting/change on a channel.
255 * API change of command_reply operation in client library. The
256 application gets now the status type received from server as well.
258 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * Removed the function just added to lib/silcutil/silcschedule.[ch].
262 * Cras fixed and optimized the packet handling even further and
263 it should work now. Minor change to the prototype of function
264 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
266 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
268 * Added new function into lib/silcutil/silcschedule.[ch]:
269 silc_schedule_with_fd to select() a specified fd. The function
270 returns after timeout expires or data arrives or goes. The
271 function is used by packet routines to wait that all data is
272 received from network.
274 * Fixed data reading from network in lib/silccore/silcpacket.c.
275 The code now assures that all data is read from the fd and then
276 continues packet processing. This was a bug fix since the code
277 used to drop some data in some circumstances.
279 * Added new function into lib/silcclient/client.[ch]:
280 silc_client_start_key_exchange to start key exchange after
281 connection has been established to server. The code internally
282 now uses this funtion but its main purpose was to provide it
283 for applications that perform their own connecting. After
284 application has created a connection it merely calls this
285 function to start the key exchange between client and server.
286 The library takes care of everything else after that.
288 Updated also lib/silcclient/README to explain the usage of
291 * Do not send to application information that connection has
292 been established. Application gets notified it by connect
295 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
297 * Applied cras's patch to add silc_schedule_one function. The
298 function runs scheduler once and returns.
300 * Fixed the scheduler after cras messed it up. The timeout
301 handling works now as it's supposed to work.
303 * Added into lib/silccore/ silcnotify.h to include notify
304 message types support. Changed silc_server_send_notify*
305 functions, in server.[ch], to support those new notify types.
306 Added the support for the notify types into client library,
307 as well. Added new notify client operation into ops.h in
310 * Changed silc_server_packet_send_to_channel to send normal
311 packets instead of just channel message packets. The function
312 is now used to send the notify packets to channels. It is not
313 used to send channel message packets anymore, as server never
316 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
317 va_arg()s as it seems to require it nowadays. I guess, if SILC
318 is compiled with older va_arg() the new code should work anyway.
320 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Splitted core library. Core library (lib/silccore) includes
323 now only SILC protocol specific core (and common) components.
324 Created new utility library (lib/silcutil) that includes more
325 generic purpose stuff. The stuff for util library was taken
326 from the old core library. This was minor and easy split.
328 * Created SILC Client Library (lib/silcclient) that includes
329 implementation of the SILC client without user interface. This
330 was major move from silc/ directory. The code has been changed
331 so that it is transparent towards the user interface. The
332 silc/ directory includes now the same user interface as before
333 and it uses the new client library. Read lib/silcclient/README.
334 Basicly, the client library performs everything else related
335 to SILC except user interface handling. Also, configuration
336 files are considered to be part of user interface and library
337 does not handle them.
339 This change also changed a lot of structures, function naming etc.
340 Most important change was that SilcClientWindow object was
341 renamed to SilcClientConnection in the client library. Created
342 also new file lib/silcclient/ops.h. Also added new files
343 silc/local_command.[ch] and silc/client_ops.[ch].
345 All these changes were made to make it easier for user interface
346 designers to create what ever user interface for the SILC client
349 It is also expected that the server will be moved to lib
350 directory as well and SILC Server Library will be created;
351 sometimes in the future.
353 * Removed Local commands from lib/silccore/silccommand.h as
354 they are application specific and new client library does not
355 handle any of those anymore.
357 * Several functions moved to lib/silcutil/silcutilc.[ch] from
358 old client implementation in silc/.
360 * Added support for callback functions in SILC_LOG_* macros.
361 Application can now set its own callbacks that will be called
362 instead of using the default functions that will always print
363 the debug messages to stderr (or stdout). Also, debugging can
364 now be disabled by setting silc_debug to FALSE and re-enabled by
365 setting it to TRUE. Note, that logging will still work even
366 if debugging is disabled.
368 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
369 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
370 silc_log_reset_debug_callbacks.
372 * To enable debugging in silc client one must give now -d
373 option on command line.
375 * Changed silc_schedule_init to automatically allocate task queues
376 if they are not allocated before calling it.
378 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
380 * Added GMP 3.1 into math library.
382 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
384 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
385 a channel in SILC network. The packet is used by servers and
386 routers to notify other routers that user has left a channel.
387 This little feature was missing until now. Added the feature
388 to protocol specification as well.
390 Added functions: silc_server_send_remove_channel_user and
391 silc_server_remove_channel_user into server.[ch].
393 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
394 lib/silccore/silcpacket.h. However, they are not implemented
397 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
399 * Fixed joining to a channel and sending channel messages
400 between server and router. The channel message sending should
401 now work inside a cell.
403 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Fixed the private message sending between server and router.
406 The private message sending should now work inside a cell.
408 * Added silc_server_replace_id into server.[ch] to replace
409 existing ID in the SILC network.
411 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
412 and silc_idlist_replace_server_id into idlist.[ch] in server.
414 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Fixed the server to server connections. Server can again now
417 connect to router. Router to router connections probably does
420 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
422 * Added dynamic protocol registering support. Now protocols can
423 registered and unregistered on the fly. Patch by cras.
425 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
427 * Added lib/contrib directory to hold routines that some platforms
428 don't have but are needed by SILC.
430 * Added getopt.c, getopt1.c and getopt.h from GNU C library
431 into lin/contrib to provide getopt() and getopt_long() for
432 those who don't have it.
434 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Added AWAY command to client. When away message is set and
437 client receives a private message packet the client automatically
438 replies to the sender with the away message.
440 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
441 bug seemed to be the cause of recent problems when compiling
444 * Added version detection support to SKE protocol specification
445 and added the new changes to the SKE implementation as well.
446 There were other minor changes in the SKE protocol as well.
448 Many changes in lib/silcske/silcske.[ch] and in
449 lib/silcske/payload.[ch].
451 * Added ^U functionality, clear input line. Patch from cras.
453 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * Mainly small bugfixes on core library. Fixed some debugging
456 logging and buffer overflow in silclog.c.
458 * Updated config.sub and config.guess on the distribution tree.
460 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
462 * Added command lagging support in server. Client may execute
463 commands now only once in two seconds.
465 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
467 * Optimized packet reception. MAC computation and checking is now
468 also more optimized. A lot previously duplicated code is now
469 used as generic by both client and server.
471 * Fixed key pair generation in clientutil.c
473 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
475 * Added into lib/silccore/silcbufutil.[ch] new function;
478 * Moved generic packet sending/encryption functions to
479 lib/silccore/silcpacket.[ch] from client and server. Some
480 rewriting of the functions.
482 * Moved all generic packet reception/decryption functions to
483 lib/silccore/silcpacket.[ch] from client and server. The
484 packet processing is now much cleaner in both client and server.
485 These were major changes in both client and server.
487 * Created many common functions in server to do packet sending.
488 Previously code were duplicated a lot, this has been removed
491 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Rewrote major parts of the ID cache system. Don't know
494 whether it is better now or not but at least the API is more
497 * Major rewrite on ID cache stuff on client because of the ID
498 cache API changes. Added idlist.c to client.
500 * Also major rewrite on ID cache stuff on server as well.
501 Major rewrite of idlist.[ch]. SilcXXXList's are now named
502 SilcXXXEntry's. We won't keep anymore idlist specific pointers
503 in hand, instead they are all put into the ID cache system now.
504 All server_idlist_* routines uses ID cache now instead of
505 traversing its own lists (those lists does not exist anymore).
506 SilcIDList though still exists. Also, SilcXXXEntry's are
509 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Finally made the SKE implementation compliant to the protocol
512 specification. All mp integers are now binary encoded as
513 opposed being HEX encoded.
515 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
518 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
519 functions: silc_[encode/decode]_pem. Also added function
520 silc_encode_pem_file to PEM encode with newlines ('\n') for
523 * SILC public keys are now encoded either PEM or binary. Same
524 option is for private keys as well. By default private keys
525 are binary encoded and public keys PEM encoded. Silly HEX
526 encoding were removed.
528 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
529 function to create fingerprints.
531 * Fixed a bug in SHA1; does not change the original data anymore.
533 * Partly implemented INFO command on client and server side.
534 Fixed CLEAR command. Changes to SERVER command; show current
535 server(s) when giving command without arguments. Added
536 VERSION command to client.
538 * Added check to server that unregistered connections cannot
539 execute commands (unless it is specificly allowed).
541 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Fixed screen refresh.
545 * Fixed channel joining bug from client. On some circumstances
546 client tried to join to a channel it had already joined.
548 * Added public key verification process into client's protocol.c.
549 The client now verifies the public key from user and saves
550 it into ~./silc/serverkeys/ directory.
552 Added into: clientutil.[ch]: silc_client_verify_server_key.
554 * Changed SKE protocol's silc_ske_initiator_finish function
555 to accept callback function that verifies the received public
556 key. Removed old silc_ske_verify_public_key function.
558 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
560 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
561 silc_pkcs_private_key[_data]_set.
563 * Made the password and public authentication more cleaner in
566 * Removed historic and obsolete protocol `channel_auth' from
567 both client and server.
569 * Removed wrong way of sending command status messages from
570 server to client in server's command.c. The old way violated
571 protocol specification.
573 Changes to silccore/silccommand.[ch]: removed
574 silc_command_encode_status_payload -> not needed anymore,
575 changed silc_command_encode_payload_va to accept extra
576 argument on variable argument list. The argument type must
577 now be provided to the function. Also, added new function:
578 silc_command_encode_reply_payload_va which is same as
579 normal command_encode_payload_va except command status type
580 is provided as extra argument.
582 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
584 * Added ~./silc directory handling. The directory includes the
