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