1 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4 that may or may not compile the mutex support in.
6 Changed the silc_mutex_alloc interface. It allocates the
7 mutex now to the sent pointer and returns TRUE or FALSE.
9 Affected file lib/silcutil/silcmutex.h.
11 * Wrote the SILC Task Queue interface to support multi-threads.
12 Affected file lib/silcutil/silctask.[ch].
14 * Wrote the SILC Scheduler to support multi-threads. Affected
15 file lib/silcutil/silcschedule.c.
17 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
19 * Implemented the SILC Mutex API and SILC Thread API for WIN32
20 in lib/silcutil/win32/.
22 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
24 * Defined SILC Mutex API and SILC Thread API and implemented
25 them for Unix. Affected files are
26 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
27 lib/silcutil/unix/silcunixmutex.c and
28 lib/silcutil/unix/silcunixthread.c.
30 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
32 * Fixed the silc_server_remove_clients_by_server's channel
33 key re-generation. The hash table handling was incorrect
34 and would not work with many channels. Affected file is
37 * Fixed some memory leaks around the server code.
39 * Rewrote the silc_server_get_users_on_channel to support IPv6
40 based Client ID's. Affected file silcd/server.c.
42 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
43 specification. However, a separate document must be written
44 to define the detailed signing procedure and the payload
45 associated with the flag. Defined the flag to the
46 lib/silccore/silcchannel.h as well.
48 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
50 * Changed the dynamic tables to static size tables in the
51 lib/silccrypt/silchmac.c.
53 * Removed GCC dependencies from the code. A patch by cras.
55 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
57 * Do not show the error "Error receiving packet bla bla"
58 in server if it really was not an error (-2 means that reading
59 is pending). Affected file silcd/server.c.
61 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
63 * Fixed a possible crash in silc_server_remove_clients_by_server
64 in silcd/server.c. Fixed there also some memory leaks.
66 * Fixed the silc_idlist_replace_client_id. It could replace
67 wrong key in the hash table. Affected file silcd/idlist.c.
69 * Do not check whether there are global users on the channel
70 if the channel->global_users is FALSE. Affected functions
71 silc_server_remove_from_one_channel and
72 silc_server_remove_from_channels in silcd/server.c. Also,
73 do not check if the removed client is local as we can be
74 sure that global client was not removed from the channel
75 and checking for global users is not needed.
77 * The silc_server_remove_clients_by_server now re-generates
78 the channel keys correctly for those channels that had
79 clients removed from them. Affected file silcd/server.c.
81 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
83 * Found the reason of random crashes in the server. We weren't
84 ignoring the SIGPIPE signal (which can be sent in write())
85 and it crashed the server. Affected file silcd/silcd.c.
87 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
89 * Assure that sock->user_data is not NULL in the function
90 silc_server_packet_send in silcd/packet_send.c.
92 * Disconnect the remote connection if it could not be added
93 to any ID lists in the server. The affected file is
96 * Check in silc_server_packet_send[_real/dest] that the
97 socket is not disconnecting and ignore the data if it is.
98 Affected file silcd/packet_send.c.
100 * Define inline to __inline on native WIN32 compilation.
101 Affected file includes/silcwin32.h.
103 * Added some explicit type casts for inline code since MSVC
104 require them. Affected files lib/silcutil/silcbuffer.h,
105 lib/trq/silcdlist.h and lib/trq/silclist.h.
107 * Print warning in log files from now on if the packet
108 decryption fails. Affected file silcd/server.c.
110 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
112 * Changed the `say' client operation's interface to accept
113 new `type' argument to indicate the type of the message sent
114 by the library. The application may filter the library's
115 messages according the type. The affected file is the
116 lib/silcclient/silcapi.h.
118 * Added two new functions to lib/silcclient/silcapi.h:
119 silc_client_del_client and silc_client_del_client_by_id.
120 Affected file lib/silcclient/idlist.c.
122 * Moved the clientincludes.h from includes/ to silc/ and
123 serverincludes.h from includes/ to silcd/.
125 * The modes for the CMODE and CUMODE are now passed as
126 uint32 for application with COMMAND_REPLY. The affected
127 file is lib/silcclient/command_reply.c.
129 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
131 * /WHOIS without arguments shows client's own information.
132 Affected file lib/silcclient/command.c.
134 * Changed PING to not accept any arguments. The specs
135 says that client can ping only the connected server so
136 requiring an argument is not needed. Affected file is
137 lib/silcclient/command.c.
139 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
141 * Fixed a fatal bug in private message sending and reception
142 encryption and decryption when using private message keys.
143 The implementation was incorrect and did not follow the
144 specification. It causd that some of the message were
145 lost since it did not use the sending and receiving keys
146 as the protocol suggests. This has been fixed and will cause
147 incompatibilities with older clients when sending private
148 message encrypted with private message keys. Affected files
149 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
150 and various other in Irssi SILC Client.
152 Added `responder' boolean argument to the functions
153 silc_client_add_private_message_key[_ske] to indicate when
154 the key is added as responder or initiator of the key
157 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
159 * Removed the silc_ske_check_version function and created
160 a SilcSKECheckVersion callback. Added also a function
161 silc_ske_set_callbacks that is now used to set all SKE
162 callbacks. The callback functions are not given to
163 the SKE functions anymore, but this function is used to
166 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
168 * Added `silc_version' argument to the silc_client_alloc
169 to define the version of the application for the library.
170 The library will use the version string to compare it
171 against the remote host's (usually a server) version
172 string. Affected file lib/silcclient/silcapi.h
174 * Added the KE protocol context to Key Agreement context
175 in client library so that we can abort the SKE if it
176 is in process when we get timeout. Affected file is
177 lib/silcclient/client_keyagr.c.
179 * Do not resolve the client ID forever if it returns in the
180 first time that such client does not exist. This was done
181 for example with private message. Affected file is
182 lib/silcclient/client_prvmsg.c.
184 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
186 * Do not add regex.h for WIN32. The affected file
187 includes/silcincludes.h.
189 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
190 not work yet 100%. It generates the DLL's automatically
191 when compiling with --with-win32 under cygwin.
193 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
195 * lib/contrib/regex.c is not compiled on WIN32.
197 * Added silc_net_get_socket_opt function to the
198 lib/silcutil/silcnet.h.
200 * Added includes/silcwin32.h for WIN32 specific includes
203 * Do not use ptime structure or any of the posix process
204 functions on WIN32 in lib/silccrypt/silrng.c.
206 * Added silc_gettimeofday to provide generic function
207 for struct timeval on all platforms. Added the function
208 to lib/silcutil/silcutil.h.
210 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
212 * Moved the lib/silccore/silcsockconn.[ch] to the utility
213 library as they clearly belong there. As a plus side we
214 can make the actual socket connection routines platform
217 Added also new generic function silc_socket_read and
218 silc_socket_write (that used to be silc_packet_[read/write].
219 The implementation of these are platform specific.
221 * Added WIN32 specific routines of silc_socket_[read/write]
222 to lib/silcutil/win32/silcwin32sockconn.c.
224 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
226 * Added preliminary support for native WIN32 compilation under
227 cygwin (using the -mno-cygwin option for GCC) to the
228 ./configure.in.pre. The --with-win32 now prepares the
229 compilation for native WIN32.
231 * Rewrote the SILC Scheduler interface in the file
232 lib/silcutil/silcschedule.h. The scheduler is now context
233 based and does not have anymore any global static scheduler.
234 Moved the Unix scheduler to the lib/silcutil/unix/ directory
235 and created lib/silcutil/win32 directory for WIN32 based
238 * Added Unix specific network routines to the
239 lib/silcutil/unix/silcunixnet.c and the old
240 lib/silcutil/silcnet.c includes now only generic routines.
242 Added WIN32 specific network routines to the
243 lib/silcutil/win32/silcwin32net.c.
245 * Added Unix specific utility functions from the
246 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
248 * Added WIN32 SILC Scheduler to the file
249 lib/silcutil/win32/silcwin32schedule.c. The code is of course
252 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Do not handle JOIN notify in the server if the target client
255 is not registered (idata->registered == FALSE). The affected
256 file is silcd/packet_receive.c.
258 * Update the nickrec->founder in event_cumode in the Irssi SILC
259 client. Affected file irssi/src/silc/core/silc-channels.c.
261 * Fixed the CUMODE_CHANGE notify handling in the server when
262 server and router are announcing their clients on channels.
263 Now the mode changes are saved and notified correctly. The
264 affected file is /silcd/packet_receive.c.
266 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
267 They really did not replace the cache entry in the ID Cache.
268 Now they do that. Affected file silcd/idlist.c.
270 * Fixed the KICK notify handling in the Irssi SILC client to
271 update the channel records so that the kicked client does not
272 appear to be on the channel. The affected file is
273 irssi/src/silc/core/silc-channels.c.
275 * Always update the conn->current_channel when executing command
276 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
278 * Fixed the KILL notify handling in Irssi SILC client to remove
279 the killed client on all channels.
281 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Fixed the silc_parse_command_line to remove extra spaces
284 from the start and end of the arguments. Affected file is
285 lib/silcutil/silcutil.c.
287 * Cancel and free any active protocol in the function
288 silc_server_close_connection. Affected file silcd/server.c.
290 * Cancel and free any active protocol in the function
291 silc_client_close_connction. Affected file is
292 lib/silcclient/client.c.
294 * Do not execute the KILL command for clients that are in
295 history (ie. they are not in the network). Affected file is
298 * Fixed KILL notify handling, client does not crash anymore.
299 Affected file irssi/src/silc/core/silc-channels.c.
301 * Reduced the default packet buffer size from 2048 to 1024 in
302 lib/silccore/silcpacket.c.
304 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
305 counter to the SKE context that is incresed when the SKE library
306 performs async operation outside the library. If the outside
307 process frees the SKE context and FREED status will be set
308 and the library will detect after the sync operation that the
309 libary is freed. The affected files are
310 lib/silcske/silcske[_status].[ch].
312 * Resolve the client entry information in the function
313 silc_client_channel_message to assure that NULL pointer is not
314 passed as client entry to the application. */
316 * Fixed the task timeout calculation to assure that there is
317 never negative timeouts. The affected file is
318 lib/silcutil/silcschedule.c.
320 * Fixed the channel user mode notification sending in server.
321 It was sent point-to-point to the router (or to server by router)
322 but it needs to be destined to a channel. The routines now
323 supports sending the channel user mode notifys to the channels
324 when announcing clients and channels. Affected files are
325 silcd/server.c and silcd/packet_receive.c.
327 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
328 It did not actually replace the old channel entry in the cache.
329 Affected file lib/silcclient/client_notify.c.
331 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
333 * Fixed a possible crash in silc_packet_send_prepare. It now
334 assures always that there is enough space in the buffer and
335 at the tail area of the buffer (for MAC).
337 Fixed the inbound buffer reallocation in silc_packet_read.
338 It was old code and did not handle the reallocation correctly.
341 The affected file is lib/silccore/silcpacket.c.
343 * Fixed buffer overflow in silc_parse_nickname in the file
344 lib/silcutil/silcutil.c.
346 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * make install generates new server keys only if there is not
351 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
354 Added check that if the NOREPLY is set then we will not send
355 the away message. This avoids infinite loop of away messages
356 if both clients are away. The affected file is
357 lib/silcclient/client_prvmsg.c.
359 * Fixed client crash if /NICK was given without arguments.
360 Affected file lib/silcclient/command.c.
362 * Server does not send the invite list in INVITE command back
363 to the client if the list was not altered. Added this notion
364 to the protocol spec as well. Affected file silcd/command.c.
366 Fixed possible crash in INVITE command by checking the
367 value of silc_server_get_client_route command.
369 * Fixed the INVITE notify type handling. The arguments are now
370 taken in correct order and client does not crash. The affected
371 file is irssi/src/silc/core/silc-channels.c.
373 Removed the "Inviting xxx to channel" message from the
374 client library away and let the application handle it.
375 Affected file lib/silcclient/command.c. Added that message
376 to Irssi SILC client's message formats.
378 * Fixed CMODE command crash in client. It now checks the
379 amount of arguments correctly and does not crash. The affected
380 file is lib/silcclient/command.c.
382 * Do not create new channel automatically in silc_channels_join
383 but check whether the channel by that name already exists.
384 Affected file irssi/silc/core/silc-channels.c.
386 * Do not send the SERVER_SIGNOFF to router if the disconnected
387 entity was the router. Affected file silcd/server.c.
389 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
390 SILC client as it was missing from there.
392 Added the handling of the KICK notify to the Irssi SILC client
393 as it was missing. Added "you have been kicked" message to
394 Irssi SILC client's message modules formats.
396 Added the handing of the KILL notify to the Irssi SILC client
397 as it was missing. Added the kill message module formats
400 The affected file is irssi/src/silc/core/silc-channels.c.
402 * The router did not save the channel mode the server announced.
403 Affected file silcd/packet_receive.c.
405 * Fixed a possible crash in INFO command in server. If the
406 server did not provide the server info it crashed. Affected
407 file silcd/command.c.
409 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * Fixed the GETKEY command in the server to check also the
412 global list. Otherwise the GETKEY would not work correctly
413 in normal SILC server. Affected file silcd/command.c.
415 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Fixed GETKEY crash, it crashed if the command did not succseed.
419 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
421 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
422 is now real and not just an macro interface to GMP.
424 Removed the entire GMP from the source tree and imported new
425 NSS MPI library instead. Reason for removing GMP is that it is
426 extremely large and compiles extremely slow. The NSS MPI
427 is only a few files and compiles in less than 10 seconds.
428 The speed is also about the same as GMP. The MPI is imported
431 If the system has GMP installed we will still use the GMP.
432 If it is not then the NSS MPI will be compiled.
434 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Merged a long nickname (127 characters long) crash bugfix from
437 Irssi CVS tree. Affected file irssi/src/core/misc.c.
439 * Merged a freed memory reference bugfix from Irssi CVS tree.
440 Affected file irssi/src/core/commands.c.
442 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
444 * Added the server's public key sving and verification to the
445 server when performing the SKE. This was missing and the
446 remote server's (or router's) public key was accepted without
447 checking whether we have it previously or trust it at all.
448 Affected file silcd/protocol.c.
450 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Check in the silc_server_timeout_remote if protocol is active
453 and make sure that the protocol's final callback is called so
454 that all memory if freed. Affected file silcd/server.c.
456 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
458 * silc_server_whois_send_reply crashed the server if the nickname
459 was 127 characters long. Affected file silcd/command.c.
461 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Added sanity check to the silc_server_new_client. If the hostname
464 is provided inside username then check that the provided hostname
465 really is the same as the resolved one. If the hostname was not
466 resolved then check it from the public key. Affected file is
467 silcd/packet_receive.c.
469 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
470 if the server disconnected us and the connection is not valid
471 anymore. Affected file irssi/src/silc/core/silc-channels.c.
473 * Moved the silc_client_[chmode|chumode|chumode_char] away from
474 the library to the lib/silcutil/silcutil.[ch].
476 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Close log file after open. Affected file
479 lib/silcutil/silclog.c.
481 * Check whether sock == NULL in silc_client_send_packet and return
482 if it is. Affected file lib/silcclient/silcclient.c.
484 * Check rec->entry == NULL in the Irssi SILC Client before
485 sending the channel message. Affecte file is
486 irssi/src/silc/core/silc-servers.c.
488 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
490 * Merged a splitted window bugfix from Irssi CVS tree. The
491 affected file is irssi/src/fe-text/textbuffer-view.c.
493 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
494 It did not print nickname.
496 * Improved the distributions system a bit.
498 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
500 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
501 irssi/src/fe-text/gui-window.c.
503 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
504 to in-active server. The affected file is
505 irssi/src/silc/core/client_ops.c.
507 * Resolve the client in USERS command reply if the entry does
508 not have username resolved. The affected file is
509 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
510 command to WHOIS command to really resolve stuff. The USERS
511 is not used any more in any critical section so WHOIS can
512 be used even though it might be slower than IDENTIFY.
514 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
517 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Changed the protocol API a bit more consistent in the
520 lib/silccore/silcprotocol.[ch].
522 * Changed the following headers to ROBODoc format:
524 lib/silccore/silcpayload.h
525 lib/silccore/silcprotocol.h
526 lib/silccore/silcsockconn.h
528 All core library headers are now formatted.
530 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Fixed a bug in Irssi SILC client; do not show that you are
533 server/router operator if you really are not. Affected file is
534 irssi/src/silc/core/client_ops.c.
536 * Renamed silc_command_free_payload to silc_command_payload_free.
537 Affected file lib/silccore/silccommand.h
539 * Added silcmath.h to include the prototoypes of various routines
540 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
543 * Changed the following headers to ROBODoc format:
545 lib/silccore/silcchannel.h
546 lib/silccore/silccommand.h
547 lib/silccore/silcid.h
548 lib/silccore/silcidcache.h
549 lib/silccore/silcmode.h
550 lib/silccore/silcnotify.h
551 lib/silccore/silcpacket.h
552 lib/silcmath/silcmath.h
554 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Added checking to the server code not to start the server if
557 ciphers and stuff are not configured properly. Affected files
558 silcd/serverconfig.[h] and silcd/server.c.
560 * Changed the layout of the header files of the public interfaces
561 in the SILC libraries. The new layout supports ROBODoc
562 documentation tool (and some others) so that it is easy to create
563 a library reference manual. All the other headers and source
564 code must still follow the CodingStyle document. Also source
565 code must not include these ROBODoc stuffs, only the headers.
566 Furthermore, all public interface headers must now be named
567 by using `silc' prefix, example: silcapi.h, silccipher.h.
568 Some files were renamed due to this. All the other headers
569 must not be used as public interfaces. I will update the
570 CodingStyle document later. Changed following headers, so far:
572 lib/silcclient/silcapi.h
573 lib/silccore/silcauth.h
574 lib/silccore/silcprivate.h
575 lib/silccrypt/silcdh.h
577 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Removed silc_client_packet_send_flush from the client library
582 as it is not needed. Affected file lib/silcclient/client.[ch].
584 * Added printing of message of unresolved authentication method
585 to the Irssi SILC client. Added it to the module formats.
586 Removed the same message from the client library.
588 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
590 * Added new distribution feature, DISTLABEL. Every distribution
591 can define own preprocessor label that can be used in the
592 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
593 file distributions, acconfig.h.pre and prepare.
595 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Added Makefile.defines_int to include the actual definitions
598 for Makefile.defines.in. Tested the new distribution system,
599 created distributions and tested installation.
601 * Added AWAY message printing to the Irssi SILC client. Added
602 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
604 * Added SCONNECT command to call the SILC's CONNECT command.
605 Cannot use CONNECT directly since Irssi uses that internally.
606 Affected file irssi/src/silc/core/silc-servers.c.
608 Added ACTION local command. It is same as ME command but takes
609 the channel as mandatory argument.
611 Rewrote some of the Irssi's help files to suite for SILC
614 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
616 * Added Makefile.defines[.in] that should for now on be included
617 in all Makefile.am file in the source tree. That file includes
618 all common compilation definitions for SILC source tree.
620 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
622 * Minor changes to the ./prepare script to change the package
623 name according the distribution name to the configure.in.
625 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
627 * Created new distribution system. Added file `distributions'
628 that defines all the distributions that can be created out of
629 the SILC source tree. The ./prepare script now reads that
630 file to determine how to prepare the distributions. The
631 first argument to the ./prepare is the name of the distribution
632 and second is the version of the distribution. If given
633 without arguments it creates the default (toolkit) distribution
634 with the default version (defined in ./prepare).
636 All Makefile.am files that are subject to the distributions
637 are now named as Makefile.am.pre. These are ./Makefile.am
638 and lib/Makefile.am. Others may be changed later.
640 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Added invite list, ban list, some key management and connection
643 error message printing to module formats in the Irssi SILC client.
645 * Added new silc_client_set_away_message to set the away message
646 that is back to the person who sent private message. The
647 affected file lib/silcclient/silcapi.h and the
648 lib/silcclient/client_prvmsg.c.
650 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Fixed the private message sending in the Irssi SILC client,
653 added local command KEY to the Irssi SILC client.
655 Added key management and key agreement message formats to the
656 irssi/src/fe-common/silc/module-formats.[ch].
658 Added USERS (alias WHO) printing, server/router operator
659 indication and LIST command printing to the module formats.
661 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Fixed channel joining notify handling, cumode notify handling
664 from Irssi SILC client.
666 * Added SILC specific module-formats to the Irssi SILC client so
667 that SILC specific message hilighting, colors etc is possible.
668 Affected file irssi/src/fe-common/silc/module-formats.[ch].
670 Added channel mode, channel user mode, actions, notices,
671 whois and whowas printing to the the module-formats.c.
673 * Fixed a bug in channel deletion in the server. The channel
674 is not left to the cache even if the channel founder auth mode
675 is set when there are no users anymore on the channel. Affected
678 * The silc_net_localhost now resolves the entire hostname including
679 the domain name. Affected file lib/silcutil/silcnet.c.
681 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Changed the ask_passphrase client operation to be ascynchronous.
684 It has now a completion callback and a context that the
685 application must call after it has got the passphrase from
686 the user. Affected files lib/silcclient/silcapi.h,
687 lib/silcclient/protocol.c, lib/silcclient/command.c and
690 Added SilcAskPassphrase callback that the application calls
691 to deliver the passphrase to the library.
693 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
694 The public key verification and especially a certificate
695 verification is asynchronous procedure.
697 Added new SILC_SKE_STATUS_PENDING status to indicate the
698 request is pending and a callback will be called to finalize
701 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
702 indicate that remote end did not send its public key (or
703 certificate), even though we require it. Added check for this
704 condition in the SKE. This was a security bug, now fixed.
706 Defined new SilcSKEVerifyCbCompletion callback that is called
707 when the verification process is completed.
709 The affected files lib/silcske/silcske_status.h and
710 lib/silcske/silcske.[ch].
712 * Changed the verify_public_key client operation to be async
713 as well. Defined SilcVerifyPublicKey callback that is used to
714 indicate the success of the public key verification process.
716 Changed the server and client to use the new async client
719 * Changed the Irssi SILC client's internal scheduler to be called
720 twice as many times as it used to be. As a result the client
721 should be a bit faster now. Affected file is
722 irssi/src/silc/core/silc-core.c.
724 * Added support to Irssi SILC client of asynchronous public key
725 verification and passphrase inquiry. Affected file is
726 irssi/src/silc/core/silc-core.c.
728 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Do not say "You have left channel %s" in client library.
731 Moved it to the application. Affected files are
732 lib/silcclient/command.c and silc/client_ops.c.
734 * Fixed silc_client_get_clients. Command context was not
735 duplicated and was freed memory in the callback. Affected
736 file lib/silcclient/idlist.c.
738 * Do not say "you are now talking..." on JOIN command in the
739 client library. The appliation must handle it.
741 * Do not say ".. changed topic to" in command reply in the
742 client libary. The application must handle it.
744 * Fixed TOPIC command sending in the client library.
746 * Fixed a memory leak in silc_client_command_free in the file
747 lib/silcclient/command.c.
749 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
751 * Imported a modified version of Irssi client to the source tree.
752 The Irssi will be used to create a new client called
753 Irssi SILC. Imported to irssi/.
755 Added silc_core_init_finish function to the Irssi. Affected
756 file irssi/configure.in.
758 A lot changes in the Makefile.ams around the irssi tree.
760 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
762 * Do not rehash if the new size is same as the old size of the
763 hash table, in the silc_hash_table_rehash*. The affected file
764 lib/silcutil/silchashtable.c.
766 * Replaced hash_table_del_by_context calls from the server
767 (when channel->user_list and client->channels) to the
768 hash_table_del as it is sufficient and faster.
770 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Added silc_hash_table_list, silc_hash_table_get and the
773 SilcHashTableList structure to provide an alternative way to
774 traverse the hash table. The affected files are
775 lib/silcutil/silchashtable.[ch].
777 * Changed the server's idlist routines to use the hash table
778 routines to optimize the code.
780 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Replaced the client entry's `channel' list and channel entry's
783 `user_list' list to hash tables for optimized lookup. Changed
784 the code to use the hash table interface around the code.
785 Affected file lib/silcd/idlist.[ch].
787 * Added `auto_rehash' boolean argument to the function
788 silc_hash_table_alloc to indicate whether the hash table should
789 auto-rehash when it thinks is appropriate time. It will
790 increase the hash table size if the there is twice as much
791 entries in the table than the size of the table, and will
792 decrease the size if there are twice as less entries than
793 the size of the table.
795 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Fixed silc_xxx_get_supported to not crash at some circumstances.
799 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * silc_idcache_purge_by_context deletes the entry now by context
802 as it is supposed to do. Affected file lib/silccore/idcache.c.
804 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
805 client is not anymore valid (WHOWAS givens the info) and not
806 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
808 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
810 * Removed the `data' and `data_len' arguments from the ID Cache
811 interfaces and added `name' argument. ID Cache does not handle
812 anymore the binary data only a names associated with given ID.
814 * When hashing a Client ID with silc_hash_id the entire ID is
815 not hashed anymore, instead only the hash of the Client ID is
816 hashed. This way we can access the Client ID from the cache
817 with Client ID but with the hash of the ID (which is a hash of
818 the nickname) as well without any difference in performance.
820 Added also silc_idcache_find_by_id_one_ext to do one on one
821 searching when we have the actual ID. Added also function
822 silc_hash_client_id_compare. The affected files are
823 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
825 * When hashing the name associated with a ID it is always done
826 in lowercase. This way we can access the cache without worrying
827 about case-sensitivity, even though, for example nicknames are
830 * Fixed a bug in server with channel message sending. It put
831 wrong ID type as destination ID. The affected file
834 * silc_idcache_del_by_context now deletes from all hash tables
835 by context. Affected file lib/silccore/idcache.c.
837 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
839 * Changed the client library to use the new ID Cache interface.
840 Changes around the source tree.
842 * Added silc_hash_table_rehash_ext to rehash with specific
843 hash function. Affected file lib/silcutil/silchashtable.[ch].
845 * Added silc_hash_string_compare to compare two strings in the
846 hash table. Affected file lib/silcutil/silcutil.[ch].
848 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
850 * Added new function silc_idcache_del_by_context into the
851 lib/silccore/idcache.[ch].
853 * Changed the server's ID list routines to use the new ID Cache
854 interface. Changes around the source tree.
856 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
858 * Added silc_hash_table_del[_by_context]_ext functions in to the
859 lib/silcutil/silchashtable.[ch].
861 Removed silc_hash_table_find_all* routines and added new
862 silc_hash_table_find_foreach to replace them.
864 Added silc_hash_table_replace_ext function as extended
865 replacing function. Separated the simple hash table interface
866 from the extended hash table interface in the file
867 lib/silcutil/silchashtable.h.
869 * Fixed minor bugs and changed it to use some of the new
870 hash table functions in lib/silccore/idcache.c
872 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Added new function silc_hash_table_find_all to return all keys
875 in the hash table by the specified key. As the hash table is
876 collision resistant it also makes it possible to have several
877 duplicate keys in the hash table. This function may be used to
878 find all of the keys from the hash.
880 Added user_context arguments to the SilcHashFunction,
881 SilcHashCompare and SilcHashDestructor to deliver user specified
884 Added new fuctions silc_hash_table_find[_all]_ext to do
885 extended lookup with specified hash and compare functions and
886 specified user contexts.
888 Added new function silc_hash_table_add_ext to add the key
889 with specified hash function and user context.
891 Added new function silc_hash_table_foreach to traverse all
892 entrys in the hash table. Added SilcHashForeach callback
895 Added new function silc_hash_table_del_by_context to delete
896 the entry only if the context associated with the key matches.
898 Affected files are lib/silcutil/silchashtable.[ch].
900 * Removed silc_hash_[server/client/channel]_id and added just
901 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
902 silc_hash_id_compare to compare two ID's using as the hash table
903 comparison function. Added also silc_hash_data to hash
904 binary data and silc_hash_data_compare to compare it.
906 * Removed silc_idlist_find_client_by_hash as it is not needed
907 anymore. Affected file silcd/idlist.[ch].
909 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
910 to use internally the SilcHashTable. The new ID Cache is a lot
911 faster than the old one. Some of the ID Cache interface was also
912 rewritten and obsolete and stupid functions were removed.
914 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Added entry_count field to the SilcHashTable to keep the number
917 of the entries in the table. Implemented the function
918 silc_hash_table_rehash. Added new function
919 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
921 Fixed a minor bug in silc_hash_table_free.
923 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
924 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
925 into the lib/silcutil/silcutil.[ch].
927 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
929 * Implemented a collision resistant hash table into the
930 lib/silcutil/silchashtable[ch]. See the header and the source
931 for the SilcHashTable API.
933 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Merged dotconf version 1.0.2 into lib/dotconf.
937 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
939 * Do not compile anything in lib/silcsim/* if the SIM support
940 is not enabled. The tree should now compile without problems
943 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Compiled the SILC under cygwin. Compiled and tested briefly
946 without problems. More tests needed. The SIMs didn't compile
949 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
951 * Fixed possible crash in silc_get_username in the
952 lib/silcutil/silcutil.c.
954 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Fixed a va_arg in silc/client_ops.c.
958 * Oops, RC5 routines were named AES and caused some problems
959 when not using SIM's. Affected file lib/silccrypt/rc5.c.
961 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Added new SilcIDIP structure into the lib/silccore/id.h and
964 replaced the old `ip' fields from all SILC ID's to that type.
965 This is a step towards IPv6 support.
967 The silc_id_get_len takes now the ID as an extra argument.
968 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
969 both IPv4 and IPv6 based ID's.
971 The affected files are lib/silccore/id.[ch] and other files
972 around the tree using these routines.
974 * Removed the ID length arguments in server from various
975 silc_server_send_notify_* routines -> they are not needed
978 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Fixed memory leak in silc_encode_pem_file in the file
981 lib/silcutil/silcutil.c.
983 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * Check minor version as well in the SKE. Affected files are
986 silcd/protocol.c and lib/silcclient/protocol.c.
988 * Added --identifier option to the server so that an identifier
989 can be when creating the public key for the server. Affected
990 file is silcd/silcd.c.
992 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
993 lib/silccrypt/silcpkcs.c.
995 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Register default ciphers and stuff when using -C option with
998 the server. Affected file sildc/silcd.c.
1000 * Put back the servers public key filename format, it is better
1001 than the new one. For now, the client keys are saved with the
1002 new filename format. The affected file silc/client_ops.c.
1004 * Implemented the Cipher API for the rest of the ciphers that
1005 did not implement it or implemented it the wrong way.
1007 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Register default ciphers and stuff when using the -S option
1010 in the client. Affected file silc/silc.c. Same also when
1011 creating new key pair with -C option.
1013 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Fixed the silc_verify_public_key client operation function to
1016 save the public keys differently. The fingerprint is now
1017 used as filename and not the hostname. This way also the
1018 client keys are saved uniquely and not with hostnames. The
1019 affected file is silc/client_ops.c.
1021 * Trimmed the silc_hash_fingerprint function to remove extra
1022 whitespaces from the end of the fingerprint. The affected
1023 file is lib/silccrypt/silchash.c.
1027 * Added silc_cipher_register_default function to register all
1028 default ciphers. It can be used when configuration files
1029 does not exist and the application does not want any specific
1030 ciphers in any specific order.
1032 The SilcDList is now used as silc_cipher_list dynamically
1033 allocated cipher list. Removed the static list all together
1034 and now all ciphers must be allocated to the dynamic list.
1035 The silc_cipher_alloc routine was changed to check only the
1038 All silc_cipher_* routines that used to return int returns
1041 The affected files lib/silccrypt/silccrypt.[ch].
1043 * The same thing was done to silc_hash_* as for silc_cipher_*
1044 routines. Affected files lib/silccrypt/silchash.[ch].
1046 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1047 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1048 Added also silc_pkcs_[un]register[_default] functions.
1049 Removed the data_context from the PKCS API.
1051 * Added silc_hmac_register_default function to register default
1052 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1053 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1054 to unregister all hmacs at once.
1056 * Register the default ciphers, hash functions, PKCSs and HMACs
1057 if client's configuration file does not exist. The affected
1060 * The client did not load the hash functions from the SIM
1061 modules at all. Added support for this. Affected file is
1062 silc/clientconfig.c.
1064 * When decoding public key with silc_pkcs_public_key_decode, check
1065 the supported algorithm only if PKCS are registered. Affected
1066 file lib/silccrypt/silcpkcs.c. The same was done with the
1067 silc_pkcs_private_key_decode.
1069 * Fixed the SILC List routines to keep the list always in order.
1070 It used to change the list's order when traversing the list but
1071 not it preserves the order. Affected file lib/trq/silclist.h.
1073 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Added the client library to use the SilcSocketConnection's
1076 reference counter (by silc_socket_dup) to prevent the bug that
1077 the socket object may be freed underneath async operation.
1079 * The name resolv library checking fixes in the configure.in.pre.
1082 * Created new version of the protocol drafts for future
1083 development. The -03 drafts are the ones that will be changed
1084 in the trunk now and the -02 will remain as they are.
1086 * Send list of CUMODE notifys to the router when announcing
1087 the channel users to the router. Affected file silcd/server.c.
1088 If the router receiving channel founder CUMODE for a channel
1089 that already has channel founder it will send CUMODE notify
1090 to the sender to remove the channel founder rights from the
1091 announced client. Affected file silcd/packet_receive.c.
1093 * The CUMODE notify may now use Server ID as well as the entity
1094 who changes the mode. Updated protocool specs.
1096 * Updated INSTALL and README files.
1098 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * New web pages in the http://silc.pspt.fi. The pages was
1105 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1107 * Implemented the [DenyConnectin] config section in the server.
1108 Added silc_server_config_denied_conn to check whether incoming
1109 connection is denied. Affected file silcd/serverconfig.[ch].
1111 * Do not check the ports when checking the incoming configuration
1112 data if the port is 0, meaning any. Affected file is
1113 silcd/serverconfig.c.
1115 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Fixed buffer overflow in silc_string_compare in the file
1118 lib/silcutil/silcutil.c.
1120 * Fixed double free in silc_server_command_leave in the file
1123 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1125 * Fixed the version checking in the server. Affected file is
1128 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Fixed the configuration data fetching when accepting new
1131 connections in the server. Affected file silcd/server.c.
1133 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Added `sender_entry' argument to the function
1136 silc_server_packet_relay_to_channel so that we can check
1137 whether some destination actually belongs to the same route
1138 the sender belongs (ie, we must not resend the packet to the
1139 sender). Affected file silcd/packet_send.[ch].
1141 * Added `servername' field to the SilcClientEntry in the server
1142 to hold the name of the server where client is from. Affected
1143 file is silcd/idlist.h.
1145 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * Moved the channel message encrypting in the router betwen
1148 router connections from silc_server_channel_message to the
1149 silc_server_packet_relay_to_channel since we want to check
1150 whether we have anybody channel before encrypting anything.
1151 Affected files silcd/packet_[receive/send].c.
1153 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1155 * Fixed the [AdminConnection] server config section to support
1156 multiple entries. Affected file silcd/serverconfig.c.
1158 * Added support into the server to check the validity of the
1159 incoming connection before executing any KE or authentication
1162 * The connection configuration is now saved to the KE and
1163 connection auth protocol contexts and not fetched anymore in
1164 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1166 * The local hosts listenning address and port is also resolved
1167 now when starting the server. We want to have the socket object
1168 to include the real address and port for the listener. Added
1169 new function silc_net_check_local_by_sock into the files
1170 lib/silcutil/silcnet.[ch].
1172 * Fixed a broadcast bug in server -> do not broadcast if we
1175 * Fixed a routing bug. Do not route broadcast packets ever.
1176 Broadcast packets must be processed always and not routed since
1177 they may be destined to some other host than yourself and thus
1178 would get routed without no good reason. Affected file is
1181 * Added function silc_server_config_is_primary_route to check
1182 whether primary router connection has been configured (a router
1183 configuration that we are initiating). If there is not, we
1184 will assume that there is only two routers in the SILC network
1185 and we will use the incoming router connection as our primary
1186 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1188 * Changed the order of the broadcasting. Broadcast _after_ the
1189 packet has been processed not before. Affected file is
1192 * Fixed a [ClientConnection] parsing bug. The port was never
1193 parsed correctly thus resulting to port 0. Affected file
1194 silcd/serverconfig.c.
1196 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1197 argument and did not set the broadcast packet flag. Affected
1198 file silcd/packet_send.c. Fixed same bug in the function
1199 silc_server_send_notify as well.
1201 * If we receive NEW_ID packet for our own ID in the server, ignore
1204 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Removed the nickname from the Private Message Payload.
1209 Updated the code and the protocol specs.
1211 * Updated protocol specs for submitting to the IETF.
1213 * Tweaked the Random Number Generator a bit. Affected file
1214 lib/silccrypt/silcrng.c. Exported a new function
1215 silc_rng_[global]_add_noise which can be used to add more
1218 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Do not parse packets with different timeout when protocol
1221 is active -> may cause problem with rekey. Affected file
1224 * When server receives signoff notify it must not create
1225 new channel key if the client is on any channels since the
1226 sender of the signoff notify will create it.
1228 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Added printing of error messages during SKE protocol from the
1231 failure packet sent by server during SKE. Affected file
1234 * Removed the client's failure_callback handling with timeout
1235 and handle it immediately when received.
1237 * The SKE library returned wrong type in SUCCESS and FAILURE
1238 packets. They must be 32 bit MSB not 16 bit MSB.
1240 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Ok, rewrote the logic of the re-key and now it seems to work.
1243 I tested it on high traffic with frequent re-keys without
1244 problems. Added hmac_receive (and renamed hmac to hmac_send)
1245 in SilcClientConnection in lib/silcclient/client.h and
1246 in SilcIDListData in silcd/idlist.h. Also, removed the
1247 SilcPacketParserContext's cipher and hmac fields as they are
1248 not needed anymore and actually caused some problems when
1249 the ciphers and hmac's changed underneath the packet parser.
1251 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1253 * If re-key protocol is active then process the incoming packets
1254 synchronously since we must assure that icoming packets encrypted
1255 with the old key is processed before the new keys is set to
1256 use. This is true other packets than for REKEY packets.
1257 Affected file silcd/server.c. The same was done to client library
1258 as well, affected file lib/silcclient/client.c.
1260 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Fixed bug in client and server to accept the force send if
1263 the packet is send from silc_[server/client]_packet_process
1264 function. Otherwise the packets are never delivered, oops.
1266 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Disable force sending of packets when REKEY protocol is active.
1269 We must assure that no packet is sent directly when rekey is
1270 performed. All packets must be sent through packet queue.
1271 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1272 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1273 function is silc_[server/client]_packet_send_real to check
1276 * Replaced the SIM paths from example config files to
1277 /usr/local/modules. Also, make install creates now
1278 /usr/local/silc/logs directory to hold all the SILC server
1281 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1283 * Made the configure.in.pre work on Solaris. Patch by salo.
1285 * Made all ciphers compatible with non-x86 machines. Defined
1286 CBC mode macros into lib/silccrypt/ciphers_def.h.
1288 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Fixed the make install.
1292 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * When MAC computation fails the silc_packet_decrypt returned 0
1295 even though it was supposed to return -1. Fixed this. The
1296 affected file is lib/silccore/silcpacket.c.
1298 * Do not replace the config files in /etc/silc (in make install)
1299 if they already exist. Affected file ./Makefile.am.
1301 * Do not send re-key packets immediately but through packet queue.
1302 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1304 * Changed silc_net_check_host_by_sock to return FALSE if the
1305 IP/DNS could not be resolved. Though, it returns the IP address
1306 now even if it could not resolve it (but returns also FALSE).
1307 Affected file lib/silcutil/silcnet.[ch].
1309 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Added silc_pkcs_decode_identifier to decode the public key's
1312 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1313 Added also silc_pkcs_free_identifier. Added also new context
1314 SilcPublicKeyIdentifier.
1316 * Added -S option to the silc client. It is used to dump the
1317 contents of the specified public key file.
1319 * Changed the PKCS api to return the public key length when
1320 setting the public key.
1322 * Fixed a fatal bug in the public and private key file loading.
1323 Affected file lib/silccrypt/silcpkcs.c.
1325 * Execute the packet parsing for client with zero (0) timeout
1326 if the protocol is active. Affected file silcd/server.c.
1328 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1330 * Made the key generation options to the silcd program. Added
1331 -C option, equivalent to client's option.
1333 * Added new [ServerKeys] config section to the server. It
1334 configures the server's public and private key.
1336 * Defined generic Public Key Payload into the protocol
1337 specification to send specific type of public keys and
1340 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1341 public key or certificate.
1343 * Implemented the GETKEY command to the server and to the
1344 client library and on user interface.
1346 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * Made preliminary `make install' work.
1350 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1352 * Added SilcServerRekey context into silcd/idlist.h.
1354 * Added the PFS support as defined in the specification to the
1355 SKE protocol. Affected files lib/silcske/*.c.
1357 * Added `ske_group' field to the SilcServerRekey context to hold
1358 the number of the SKE group that is used with PFS in re-key.
1359 Affected file silcd/idlist.h.
1361 * Added PFS re-key support to the server. Affected file is
1364 * Added silc_protocol_cancel to cancel execution of the next
1365 state of the protocol. Affected file is
1366 lib/silccore/silcprotocol.[ch].
1368 * Added the re-key support with and without PFS to the client
1369 library. Re-key is performed once in an hour, by default.
1371 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1372 Added silc_client_rekey_callback and silc_client_rekey_final.
1373 Affected files are lib/silcclient/protocol.[ch] and
1374 lib/silcclient/client.[ch].
1376 * Removed the `hmac_key' and `hmac_key_len' fields from the
1377 SilcClientConnection structure; not needed. Affected file is
1378 lib/silcclient/client.h.
1382 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * Do not ask whether user wants to use the negotiated private key
1385 for private messages, just use it. Affected file is
1386 silc/local_command.c.
1388 * Added `send_enc_key' and `enc_key_len' fields to the
1389 SilcIDListData structure since they are needed in the re-key
1390 phase. Affected file is silcd/idlist.[ch].
1392 * Implemented the simple re-key protocol into the server.
1393 Affected files silcd/server.c and silcd/protocol.[ch]. The
1394 re-key will be performed once in an hour, by default.
1396 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1397 Added silc_server_rekey, silc_server_rekey_callback and
1398 silc_server_rekey_final.
1400 * Removed Tunneled flag from the protocol. Updated the code
1401 and the specifications.
1403 * Adde `pfs' field to the SilcIDListData to indicate whether
1404 the PFS is to be performed in the re-key. Affected file is
1407 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1410 int64 of at least the xintXX size. If void * is less that 4
1411 bytes uint32 * will be used. Defined bool as boolean.
1413 * Changed _ALL_ unsigned long and unsigned int to uint32,
1414 unsgined short to uint16 in the source tree.
1416 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1417 not handle clients that has entry->data.registered == FALSE.
1418 They are not in the network anymore. Affected file is
1421 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1423 * Implemented the sending of the SERVER_SIGNOFF notify in the
1424 server. Affected file is silcd/server.c.
1426 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1427 Added also silc_notify_payload_encode_args into the
1428 lib/silccore/silcnotify.[ch].
1430 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1431 Affected file silcd/packet_receive.c.
1433 * Implemented the SERVER_SIGNOFF notify handling in the client
1434 library. Affected file lib/silcclient/client_notify.c. Also,
1435 implemnted the printing of the SERVER_SIGNOFF info to the
1436 application. Affected file silc/client_ops.c.
1438 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1439 if the deleting was successful. Affected file silcd/idlist.[ch].
1441 * Added support for public key authentication in the connection
1442 authentication protocol in the client library. Affected file
1443 lib/silcclient/protocol.c.
1445 * Changed the server's silc_idlist_get_clients_by_* interface
1446 to support already allocated array so that new entries may be
1447 added to pre-allocated array. Affected file silcd/idlist.[ch].
1448 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1449 and command replies.
1451 * All command reply functions in the server now calls the
1452 pending command callback even if error occured. This way the
1453 error will be delivered to the client as well. Affected files
1454 silcd/command.c and silcd/command_reply.c.
1456 * Fixed INFO command to return local server's info if no server
1457 was provided. Affected file lib/silcclient/command.c.
1459 * Removed RESTART command for good. Updated the code and the
1462 * Rewrote parts of the task system. It is a bit simpler now.
1463 Removed unsued task priorities. The affected files are
1464 lib/silcutil/silctask.[ch].
1466 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Moved the USERS printing from the library to the application.
1469 Affected files lib/silcclient/command.c and silc/client_ops.c.
1471 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1475 * Added channel key re-key support. The re-key is perfomed
1476 only by the router and is done once in an hour. Added `rekey'
1477 field to the SilcChannelEntry in the server. Affected files
1478 silcd/server.c and silcd/idlist.h.
1480 * Added silc_task_unregister_by_context into the file
1481 lib/silcutil/silctask.[ch].
1483 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1485 * Added SILC_UMODE_GONE mode to indicate when the client is not
1486 present in the SILC network. Added also support to the local
1487 command AWAY that will set this mode. Added support of showing
1488 "xxx is gone" in WHOIS command. The USERS command shows the
1489 gone status as well.
1491 * Fixed setting server and router operator privileges in the
1492 server's UMODE command. Affected file silcd/command.c.
1494 * Merged the SKE KE1 and KE2 payloads into one payload. The
1495 new KE payload is equivalent to the old KE2 payload.
1497 Cleaned up the SKE Start Payload parsing. It now uses the
1498 simple buffer unformatting to do the parsing. A lot faster
1501 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1502 to the SKE that is used to indicate whether both of the SKE
1503 parties should perform authentication. By default only the
1504 responder performs authentication. By setting this flag also
1505 the initiator must do authentication. By default it is unset
1506 since in normal SKE case, client to server connection, only
1507 the responder should do authentication. When doing SKE between
1508 two clients both should perform authentication. Updated the
1509 code and the protocol specs.
1511 * A little fix to IDENTIFY command in the server. Search the
1512 client first by hash not nickname. Affected file is
1515 * Fixed the silc_client_close_connection to support closing
1516 the client to client connections wihtout deleting too much
1517 data. Affected file lib/silcclient/client.c.
1519 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1520 are received if protocol used to be active but is not anymore
1521 the application would crash due to NULL pointer dereference.
1522 Affected files silcd/server.c and lib/silcclient/client.c.
1524 * Added `hash' field to the SilcClientConnection to include
1525 the hash function negotiated in the SKE protocol.
1527 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1528 to set the channel founder authentication data. A client can
1529 claim the founder rights later by providing the authentication
1530 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1531 This way the channel founder can regain the channel founder
1532 privileges even it is left the channel. This works only on
1533 local server and the client must be connected to the same
1534 server to be able to regain the founder rights. Updated the
1535 protocol specs accordingly.
1537 Added support to the CMODE command in the client to set the
1538 founder auth data. Read the README to see how to set it.
1540 Added support to the CUMODE command to claim the founder
1541 rights. Read the README to see how to do it.
1543 Added support for the founder authentication to the Channel
1544 Entry in the server. Affected file silcd/idlist.h.
1546 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1547 server's CMODE command. Affected file silcd/command.c.
1549 * Added the following new functions into lib/silccore/silcauth.[ch]:
1550 silc_auth_get_method and silc_auth_get_data.
1552 * The server now saves the remote hosts public key to the
1553 SilcIDListData pointer. Affected file silcd/protocol.c.
1555 * The normal server now does not remove the channel entry from
1556 the cache if the founder authentication data is set. It used
1557 to remove it if the founder was the last one on the channel on
1558 the server and left the channel. The auth data is saved and
1559 if the channel is re-joined later the old entry is used with
1560 the old auth data. Affected files silcd/command_reply.c and
1563 * Removed the `pkcs' field from the SilcIDListData structure
1564 in the server; it is not used. Affected file silcd/idlist.h.
1566 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Fixed packet processing on slow links. Partial packets were
1569 never re-processed because the incoming data buffer was cleared
1570 by the application. Application must not directly clear the
1571 sock->inbuf, the packet processing routines handle it. Fixed
1572 this in client library and in server.
1574 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Fixed the WHOIS and IDENTIFY send reply function to really
1577 check whether to send list or just one entry. Affected file
1580 * Cleaned up the LEAVE command's channel key distribution. The
1581 affected file silcd/command.c.
1583 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1584 can enforce the channel mode as well. In that case the ID
1585 includes the ID of the server. The code now enforces the
1586 mode change if the router have different mode than the server.
1588 * The notify client operation with CMODE_CHANGE notify can now
1589 return NULL client_entry pointer if the CMODE was not changed
1590 by client. Application must check for this.
1592 * Added <Server ID> argument to INFO command to support server
1593 info fetching by Server ID.
1595 * Added silc_server_announce_get_channel_users to get assembled
1596 packets of channel users of the specified channel. Affected
1597 file silcd/server.[ch].
1599 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1600 was freed underneath the ID Cache.
1602 * Re-announce clients when the server received CHANNEL_CHANGE
1603 notify from the router. Affected file silcd/packet_send.c.
1605 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1608 crashed since it did not handle the fact that there is no cipher
1609 called "3" and didn't check the error condition. Now fixed.
1611 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1612 flag. It can be used to send message requests.
1614 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1616 * Implemented the RESTART command in the client.
1618 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1619 notice type messages. Added notice printing to the user
1622 * The channel keys are not re-generated if the channel's mode
1623 is PRIVKEY, ie private key on the channel exists. Affected
1624 files silcd/server.c and silcd/command.c.
1626 * Fixed a little bug in channel message delivery when channel
1627 private keys are set in the server. Affected file is
1628 silcd/packet_send.c.
1630 * Changed the setting on channel->on_channel = TRUE from the
1631 silc_client_save_channel_key to the JOIN command reply. The
1632 key payload is not received if the private channel key is set.
1633 Affected file lib/silcclient/command_reply.c and the
1634 lib/silcclient/client_channel.c.
1636 * When the CMODE_CHANGE notify is sent and the channel private
1637 key mode is removed the channel key must be re-generated in
1638 other cells as well. Added this support for the router in the
1639 silcd/packet_receive.c.
1641 * Added new local command NOTICE to send notice message on
1642 channel. Affected file silc/local_command.[ch].
1644 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * Added new local command ME to the client. It is used to send
1647 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1648 some action. Affected file silc/local_command.[ch].
1650 * Changed channel_message and private_message client operations
1651 to deliver the message flags to the application. Added also
1652 the `flags' arguments to the silc_client_send_channel_message
1653 and silc_client_send_private_message functions. Affected file
1656 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1658 * Redefined the Private Message Payload to support private message
1659 keys and to support the new private message flags. Updated
1660 the protocol specs. Flags makes it possible to have for example
1661 CTCP style messages.
1663 * Added new type SilcPrivateMessagePayload and defined an API
1664 for it in the lib/silcclient/silcprivate.[ch].
1666 * Tested private message private keys successfully. Tested the
1667 private message key set, unset and list commands with the new
1670 * Redefined the Channel Message Payload to include the channel
1671 message flags (equal with private message flags) to support
1672 for example CTCP style messages.
1674 * Defined some of the message (for channel and private message)
1675 flags. Updated the protocol specs and added the flags to the
1676 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1678 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1680 * Added SilcKeyAgreementStatus type to the key agreement routines
1681 to indicate the current status and error if one occured.
1682 The status types are defined in the lib/silcclient/silcapi.h.
1684 * Added new local command KEY that is used to set and unset private
1685 keys for channels, set and unset private keys for private messages
1686 with remote clients and to send key agreement requests and
1687 negotiate the key agreement protocol with remote client. The
1688 key agreement is supported only to negotiate private message keys,
1689 it currently cannot be used to negotiate private keys for channels,
1690 as it is not convenient for that purpose.
1692 * Fixed a minor pending callback setting bug in the function
1693 silc_client_get_client_by_id_resolve, now the function works.
1694 Affected file lib/silcclient/idlist.c.
1696 * Added function silc_net_get_local_port to get local bound
1697 port by socket. Added to lib/silcutil/silcnet.[ch].
1699 * Added `sockets' and `sockets_count' fields to the SilcClient
1700 object. They hold the sockets of the listenning sockets in
1701 the client. Listenning sockets may be for example the key
1702 agreement server. Affected file lib/silcclient/client.[ch].
1703 Added functions the silc_client_add_socket and the
1704 silc_client_del_socket. They are exported to the application
1707 * Added ~./silc/clientkeys to support other client's public keys.
1709 * Renamed verify_server_key client operation to verify_public_key
1710 and added one argument to indicate the type of the connection
1711 (server, client etc.).
1713 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Added silc_server_connection_auth_request to handle the
1716 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1717 silcd/packet_receive.[ch].
1719 * Added silc_server_send_connection_auth_request into the
1720 silcd/packet_send.c to send the connection auth request packet.
1722 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1725 * Fixed the public key authentication in responder side in the
1726 server. The `auth_data' pointer includes the SilcPublicKey
1727 not the path to the public key. Affected file silcd/protocol.c.
1729 * Implemented the public key authentication in the initiator side
1730 in the server. Affected file silcd/protocol.c.
1732 * Removed the [RedirectClient] config section from the server
1733 configuration. Is not needed and I don't want to implement it.
1735 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Cleaned up the CMODE command in the server. It now works
1738 correctly and supports all the modes defined in the protocol.
1739 Affected file is silcd/command.c.
1741 * Added `hmac_name' field to the SilcChannelEntry in the server
1742 to hold the default HMAC of the channel. It can be set when
1743 creating the channel (with JOIN command). Affected files
1746 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1747 type to indicate the change of the current cipher and hmac
1748 on the channel. Client can safely ignore the <cipher> argument
1749 (if it chooses to do so) since the CHANNEL_KEY packet will
1750 force the channel key change anyway. The <hmac> argument is
1751 important since the client is responsible of setting the new
1752 HMAC and the hmac key into use.
1754 * Fixed the CMODE command in the client library as well.
1756 * Tested CMODE command in router environment successfully.
1758 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1760 * Show the version of the remote client (or server) when connecting
1761 to the server. It is logged to the log file. Affected file
1762 is silcd/protocol.c.
1764 * Fixed the KILLED notify handling in the client library. The
1765 client must be removed from all channels when receiving the
1768 Also, do not remove the client entry when giving the KILL
1769 command but when the KILLED notify is received.
1771 * Removed silc_idlist_find_client_by_nickname from the server.
1772 Not needed anymore. Affected files silcd/idlist.[ch].
1774 * Implemented the CHANNEL_CHANGE notify type handling to the
1775 server. Affected file silcd/server.c.
1779 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Added silc_server_send_notify_invite to send the INVITE
1782 notify between routers.
1784 * Implemented the INVITE command correctly to the server.
1786 * Implemented the INVITE notify type handling in the server.
1788 * Implemented the INVITE command to the client library and on the
1791 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Added function silc_server_get_client_resolve to find the
1794 client entry by ID from all ID lists and then resolve it
1795 (using WHOIS) if it cannot be found. Affected file is
1798 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Implemented the BAN command to the client library.
1802 * The JOIN command in the server now checks the invite list
1805 * Changed the silc_command_reply_payload_encode_va and the
1806 silc_command_payload_encode_va to support that if argument is
1807 NULL it ignores and checks the next argument. Affected file
1808 lib/silccore/silccommand.c.
1810 * Added silc_server_send_notify_ban to send the BAN notify
1811 type between routers.
1813 * Chaned the silc_notify_payload_encode to support that if
1814 argument is NULL it ignores and checks the next argument.
1815 Affected file lib/silccore/silcnotify.c.
1817 * Tested ban lists in router environment successfully.
1819 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Implemented BAN command to the server, in silcd/command.[ch].
1823 * Removed the BAN and INVITE_LIST modes from the CMODE command
1826 * Added function silc_string_match to regex match two strings.
1827 Affected files lib/silcutil/silcutil.[ch].
1829 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Redefined parts of the SilcChannelEntry in the server to support
1832 the new ban and invite lists.
1834 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1836 * Redefined the INVITE command. The same command can be used to
1837 invite individuals to the channel but also to manage the invite
1838 list of the channel (to add to and remove from the invite list).
1839 Updated the protocol specs.
1841 * Added new command SILC_COMMAND_BAN that can be used to manage
1842 the ban list of the channel. Updated the protocol specs.
1844 * Removed the channel modes: the SILC_CMODE_BAN and the
1845 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1846 in the CMODE command. The equivalent features are now available
1847 using INVITE and BAN commands. Updated the protocol specs.
1849 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1850 in the network about change in the current ban list. The notify
1851 type is not used by the client.
1853 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1854 support the invite lists.
1856 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Added new function silc_string_regexify that converts string
1859 including wildcard characters into regex string that can
1860 be used by the GNU regex library. Added into the file
1861 lib/silcutil/silcutil.[ch].
1863 Added silc_string_regex_combine to combine to regex strings
1864 into one so that they can be used as one regex string by
1865 the GNU regex library. Added into the file
1866 lib/silcutil/silcutil.[ch].
1868 Added silc_string_regex_match to match two strings. It returns
1869 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1871 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Imported GNU regex to the soruce tree into lib/contrib.
1874 Fixed some compiler warning from the regex.c.
1876 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1878 * Fixed MOTD command in the server to work in router environment.
1880 * Fixed the MOTD command in the client library to support
1881 the server argument in the command.
1883 * Added `nickname_len' argument to the silc_idlist_add_client
1884 in the server, as the `nickname' argument may be binary data
1887 * Added silc_idlist_get_channels to return all channels from
1890 * Implemented LIST command to the server. Affected file is
1893 * Implemented the LIST command to the client library and on the
1896 * Added [<user count>] argument to the LIST command reply.
1897 With private channels the user count is not shown.
1899 * Updated TODO and README.
1901 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * The client entry's data.registered must be TRUE even with
1904 global client entry on global client list. The data.registered
1905 is used to check whether the client is anymore in the network,
1906 for example with WHOWAS command so it must be valid.
1908 * Fixed the WHOWAS command in the server. It now actually works
1909 in router environment. Added function into silcd/command_reply.c
1910 silc_server_command_reply_whowas_save.
1912 * Added silc_idlist_purge function to the silcd/idlist.c
1913 to periodically purge the ID Cache.
1915 * Fixed INFO command in the server. It works now in router
1916 environment. Added <server name> argument to the INFO command
1917 reply. Updated the protocol specs.
1919 * Fixed minor bug in silc_idcache_purge to not purge if the
1920 expire value is zero.
1922 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1923 they were buggy because of the WHOWAS information.
1925 * Fixed local command MSG to handle the async resolving of
1926 the remote client properly. It used to fail the first MSG.
1927 Affected file silc/local_command.c.
1929 * Added `data_len' field to SilcIDCache context.
1931 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1933 * Update TODO. Todo in commands in the server.
1935 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1938 used by routers as broadcast packet to inform other routers
1939 about the changed user mode.
1941 Implemented the notify handling in the server. Affected file is
1942 silcd/packet_receive.c. Added the function
1943 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1945 * Added new generic Channel Payload and deprecated the New Channel
1946 Payload. The New Channel Payload is now the generic Channel
1949 * Added new argument `mode' to the silc_server_send_new_channel
1950 as it is required in the Channel Payload now.
1952 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1953 and created a new and real SilChannelPayload to represent the
1954 new generic Channel Payload. Implemented the encode/decode
1955 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1957 * Added silc_server_get_client_channel_list to return the list
1958 of channels the client has joined for WHOIS command reply.
1959 Affected file silcd/server.[ch].
1961 * Implemented the channel list sending in the WHOIS command reply
1962 in server and in the client.
1964 Implemented the channel list displaying on the user interface
1965 as well. Affected file silc/client_ops.c.
1967 * Added silc_channel_payload_parse_list to parse list of Channel
1968 Payloads. It returns SilcDList list of SilcChannelPayloads.
1969 Client for example can use this function to parse the list of
1970 channels it receives in the WHOIS command reply. The caller
1971 must free the list by calling silc_channel_payload_list_free.
1972 Affected files lib/silccore/silcchannel.[ch].
1974 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Added one new argument <user mode> to the WHOIS command reply
1977 to return the mode of the user in SILC. Updated the protocol
1980 Implemented it to the server and client.
1982 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * Fixed the mode printing on the user interface on joining.
1985 Affected file silc/client_ops.c.
1987 * Implemented the UMODE command and user modes in general to the
1988 client library and to the user interface.
1990 * Implemented the UMODE command to the server.
1992 * The server now sends UNKNOWN_COMMAND error status if client sends
1993 unknown command. Affected file silcd/command.c.
1995 * All server commands now handle the command identifier the right
1996 way when sending the command reply to the client. The client can
1997 use to identify the command replies with the identifier.
1999 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Added silc_server_get_client_route to resolve the route to
2002 the client indicated by the client ID. Affected file is
2005 * Added silc_server_relay_packet as general function to relay
2006 packet to arbitrary destination. This deprecates functions
2007 like _send_private_message_key, _relay_notify etc. Affected
2008 file is silcd/packet_send.[ch].
2010 Removed silc_server_send_key_agreement,
2011 silc_server_send_private_message_key and
2012 silc_server_packet_relay_notify functions from the file
2013 silcd/packet_send.[ch].
2017 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2018 server. Affected file silcd/packet_receive.[ch].
2020 * Implemented the KILL command to the client. Implemented the
2021 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2022 Affected files lib/silcclient/command[_reply].c and
2023 lib/silcclient/client_notify.c. Implemented the KILL notify
2024 printing in the user inteface.
2026 * Fixed a lot silc_parse_nick memory leaks from the client
2027 library in the file lib/silcclient/command.c.
2029 * Changed the silc_server_send_notify_on_channels's `sender'
2030 argument from SilcSocketConnection to SilcClientEntry to
2031 check the sender as entry and not as connection object and not
2032 to send to the client provided as argument. The affected file
2033 is silcd/packet_send.[ch].
2035 * The notify packets that are destined directly to the client used
2036 to not to be processed by the server. Now changed that and the
2037 server processes all notify packets. After relaying the packet
2038 to the client the notify packet is processed in the server.
2040 * The silc_server_free_client_data now checks whether there is
2041 pending outgoing traffic for the client and purges the data to
2042 the network before removing the client entry.
2044 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2047 an client is killed from the SILC Network. Updated the protocol
2050 Added new function silc_server_send_notify_killed to the
2051 silcd/packet_send.[ch].
2053 * Added function silc_server_packet_relay_notify to relay notify
2054 packets that are destined directly to a client. In this case
2055 the server does not process the notify packets but merely relays
2056 it to the client. Affected file silcd/packet_send.[ch].
2058 Added also silc_server_packet_process_relay_notify to check
2059 whereto relay the notify. Affected file is
2060 silcd/packet_receive.[ch].
2062 * Implemented the KILL command to the server.
2066 * Added the backup schema desgined last fall to the protocol
2067 specs for everyone to see. The specification is in the
2068 *-spec-xx.txt draft and the packet type definitions for the
2069 backup routers is in *-pp-xx.txt draft. Thusly, added also
2070 new packet type SILC_PACKET_CELL_ROUTERS.
2072 * A big security problem in the implementation discovered. The
2073 signoff of an client did not cause new channel key generation
2074 which it of course should've done. The channel keys must be
2075 always re-generated when client leaves (or signoffs) the channel.
2076 The silc_server_remove_from_channels funtion now handles
2077 the channel key re-generation.
2079 * Added `sender' argument to the silc_server_send_notify_on_channels
2080 to not to send the client provided as argument. Affected file
2081 silcd/packet_send.[ch].
2083 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Implemented OPER and SILCOPER commands into the server and
2088 * Added silc_auth_verify and silc_auth_verify_data to verify
2089 the authentication directly from the authentication payload.
2090 It supports verifying both passphrase and public key based
2091 authentication. Affected file lib/silccore/silcauth.[ch].
2093 * Added `hash' field to the SilcIDListData structure. It is the
2094 hash negotiated in the SKE protocol. Affected file is
2097 * Slight redesigning of the SilcAuthPayload handling routines.
2098 Do not send SilcPKCS but SilcPublicKey as argument.
2100 * Implemented the public key authentication support to the
2101 serverconfig. The public key is loaded from the provided path
2102 and saved as authentication data to void * pointer. Thus,
2103 changed the unsigned char *auth_data to void *auth_data;
2105 * Fixed SHUTDOWN command to send the reply before the server
2106 is shutdown. :) Affected file silcd/command.c.
2108 * Fixed fatal bug in CONNECT command. The hostname was invalid
2109 memory and server crashed. Affected file silcd/command.c.
2111 * Fixed fatal bug in CLOSE command. The server_entry became
2112 invalid but was referenced later in the command. Affected file
2115 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Fixed fatal bug in failure packet handling. Server ignored
2118 the failure and thus crashed when it came.
2122 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2125 that the command may be executed only once in (about) 2 seconds.
2126 The old SILC_CF_LAG flag is same but allows command bursts up
2127 to five before limiting.
2129 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2130 server code. Various commands now includes the CF_LAG_STRICT
2131 flag to disallow any kind of miss-use of the command.
2133 * Fixed the silc_buffer_unformat to not to allocate any data
2134 if the length of the data is zero. It used to allocate the
2135 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2137 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Changed the format of AdminConnection configuration section
2140 in the server. Added username of the admin to the format.
2141 Affected files silcd/serverconfig.[ch].
2143 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2144 to return admin configuration data by host, username and/or
2147 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Implemented WHOWAS command to the server. Added the functions:
2151 silc_server_command_whowas_parse,
2152 silc_server_command_whowas_send_reply,
2153 silc_server_command_whowas_from_client and
2154 silc_server_command_whowas_from_server
2156 * Added <Client ID> argument to the WHOWAS command reply. Updated
2157 the protocol specs accordingly.
2159 * Implemented WHOWAS command and command_reply to the client
2162 Implemented the WHOWAS printing on the user interface.
2164 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Added new argument to the WHOWAS command reply, the real name.
2167 It is an optional argument. Updated the protocol specs.
2169 * Added SilcIDCacheDestructor callback that is registered when
2170 the SilcIDCache is allocated. The callback is called when
2171 an cache entry in the ID Cache expires, or is purged from the
2172 cache. Added into lib/silccore/idcache.[ch].
2174 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2175 to destruct the client entries when the cache entry expires.
2176 Other ID Cache's in server and in the client library ignores
2179 * If the ID Cache entry's `expire' field is zero then the entry
2180 never expires. Added boolean `expire' argument to the
2181 silc_idcache_add function in the lib/silccore/idcache.[ch].
2182 If it is TRUE the default expiry value is used.
2184 * Added silc_server_free_client_data_timeout that is registered
2185 when client disconnects. By default for 5 minutes we preserve
2186 the client entry for history - for WHOWAS command.
2188 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * Added support to the server to enforce that commands are not
2191 executed more than once in 2 seconds. If server receives
2192 commands from client more frequently, timeout is registered
2193 to process the commands. Affected file silcd/command.c.
2194 Added new function silc_server_command_process_timeout.
2196 * Changed NICK_NOTIFY handling in client library to check that
2197 if the client's nickname was changed, so there is no need to
2198 resolve anything from the server.
2200 * Removed error printing from the WHOIS and IDENTIFY commands.
2201 If error occurs then it is ignored silently in the client library.
2202 The application, however, may map the received error to
2203 human readable error string. The application currently maps
2204 the NO_SUCH_NICKNAME error to string.
2206 * Made the command status message public to the application. Moved
2207 them from lib/silcclient/command_reply.c to
2208 lib/silcclient/command_reply.h. The application can map the
2209 received command status to the string with the
2210 silc_client_command_status_message function.
2212 * Added check to the server to check that client's ID is same
2213 as the Source ID in the packet the client sent. They must
2216 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2218 * Added dist-bzip hook to the Makefile.am to make bzip2
2219 compressed distributions.
2221 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2223 * Server now enforces the maximum length for the nickname and
2224 the channel as protocol specification dictates. 128 bytes for
2225 nickname and 256 bytes for channel name.
2227 * Moved the WHOIS printing to the application. The client libary
2228 does not print out the WHOIS information anymore, the application
2229 must do it. Renamed silc_client_command_reply_whois_print to
2230 the silc_client_command_reply_whois_save.
2232 The client's idle time is also sent to the application now, and
2233 the idle is shown on screen.
2235 * Added silc_client_command_reply_identify_save to save the
2236 received IDENTIFY entries.
2238 * Do not check for channel private keys in message sending and
2239 reception if the channel does not have the PRIVKEY mode set.
2240 Affected file lib/silclient/client_channel.c.
2242 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2245 just surfaced after chaning the JOIN procedure.
2247 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Added silc_client_get_clients_by_list to get client entries
2250 from Client ID list, that is returned for example by JOIN
2251 and USERS command replies. The application should use this
2252 function for example when JOIN command reply is received to
2253 resolve the clients already on the channel (library does not
2254 do that anymore as USERS command reply is not used in the JOIN
2255 procedure anymore). Affected files lib/silcclient/silcapi.h and
2256 lib/silcclient/idlist.c.
2258 * JOIN command reply and USERS command reply returns now SilcBuffer
2259 pointers instead of unsigned char pointers when returning
2260 the client list and mode list.
2262 * Added <Client ID> argument to the JOIN command reply, mainly
2263 for the server to identify for which client the command was
2264 originally sent. Updated protocol specs accordingly.
2266 * Added SilcDlist private_key pointer to the SilcChannelEntry
2267 in the client to support the channel private keys. Affected
2268 file is lib/silcclient/idlist.h.
2270 * Added SilcChannelPrivateKey argument to the function
2271 silc_client_send_channel_message so that application can choose
2272 to use specific private ke if it wants to. If it is not provided,
2273 the normal channel key is used, unless private keys are set.
2274 In this case the first (key that was added first) is used
2275 as the encryption key.
2277 * Implemented the support for channel private key handling.
2278 Implemented the following functions:
2280 silc_client_add_channel_private_key,
2281 silc_client_del_channel_private_keys,
2282 silc_client_del_channel_private_key,
2283 silc_client_list_channel_private_keys and
2284 silc_client_free_channel_private_keys
2286 Affected file lib/silcclient/client_channel.c.
2288 * Added the support for the private keys in the channel message
2289 sending and encryption and in the message reception and
2290 decryption. Affected funtions are
2291 silc_client_send_channel_message and silc_client_channel_message.
2293 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Added SKE's key verify callback to the client library's
2296 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2298 * Removed the statement that server (or router) must send USERS
2299 command reply when joining to the channel so that the client
2300 knows who are on the channel. Instead, the client list and
2301 client's mode list is now sent in the JOIN command reply to the
2302 client who joined channel. This is better solution.
2304 * Added function silc_server_get_users_on_channel and function
2305 silc_server_save_users_on_channel to the silcd/server.[ch].
2307 * Removed function silc_server_command_send_users from the
2310 * Do not show topic on the client library anymore. The topic is
2311 sent in the command reply notify to the application and the
2312 application must show the topic now.
2314 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * Added client searching by nickname hash into the IDENTIFY and
2317 WHOIS commands in the server as they were clearly missing from
2318 them. Affected file is silcd/command.c.
2320 * Fixed a bug in private message receiving in the client library.
2321 The remote ID was freed and it wasn't supposed, now it is
2324 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2326 * Minor fix to the channel payload; allocate the data area, as it
2327 needs to be of specific length.
2329 * If the key agreement port is zero then the operating
2330 system will define the bound port. Affected files are
2331 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2333 * Added new function silc_channel_payload_decrypt into the file
2334 lib/silccore/silcchannel.[ch].
2336 * Moved the channel message etc, check from silc_packet_decrypt
2337 to applications. The library calls now a generic
2338 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2339 when the packet is either normal or special. This was done to
2340 allow more wide range of checking that was not allowed when
2341 the code was in library. Now applications can do virtually any
2342 checks to the packet and return to the library the decision how
2343 the packet should be processed. Affected files are
2344 lib/silccore/silcpacket.[ch].
2346 Added silc_server_packet_decrypt_check to the server and
2347 silc_client_packet_decrypt_check to the client library.
2349 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2350 to send with specified source and destination information.
2352 * Channel message delivery between routers was broken after the
2353 channel key distribution was fixed earlier. The channel key
2354 was used be to distributed to other routers as well which is not
2355 allowed by the protocol. Now this is fixed and channel keys
2356 really are cell specific and the channel message delivery between
2357 routers comply with the protocol specification.
2359 * Fixed various commands in server to check also the global list
2360 for the channel entry and not just the local list. The affected
2361 file silcd/command.c.
2363 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Added assert()s to buffer formatting and unformatting routines
2366 to assert (if --enable-debug) when error occurs. Affected
2367 file: lib/silcutil/silcbuffmt.c.
2369 * Changed to auto-reconnect to check whether the remote host is
2370 router and register the re-connect timeout if it is. It used
2371 to check that whether we are normal server, but router must do
2372 auto-reconnect with another router as well. Affected file
2375 * Removed the [<key len>] option from CMODE command as the cipher
2376 name decides the key length, nowadays. See the defined ciphers
2377 from the protocol specification.
2379 * Added [<hmac>] option to the CMODE command to define the HMAC
2380 for the channel. Added SILC_CMODE_HMAC channel mode.
2382 * Added [<hmac>] option for the JOIN command so that user can
2383 select which HMAC is used to compute the MACs of the channel
2386 * Added Hmac field to the Channel Message Payload. The integrity
2387 of plaintext channel messages are now protected by computing
2388 MAC of the message and attaching the MAC to the payload. The
2389 MAC is encrypted. Now, it is clear that this causes some
2390 overhead to the size of the packet but rationale for this is that
2391 now the receiver can verify whether the channel message decrypted
2392 correctly and also when private keys are set for the channel the
2393 receiver can decrypt the packet with several keys and check from
2394 the MAC which key decrypted the message correctly.
2396 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2397 lib/silccrypt/silccipher.[ch].
2399 * Added silc_hash_len to return the digest length into the
2400 lib/silcrypt/silchash.[ch].
2402 * Rewrote parts of Silc Channel Payload interface in the
2403 lib/silccore/silcchannel.[ch]. The encode function now also
2404 encrypts the packet and parse function decrypts it.
2406 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Fixed a minor formatting bug in the SKE's key material processing.
2409 It actually might have processed the keys wrong way resulting
2412 * Redefined the mandatory HMAC algorithms and added new algorithms.
2413 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2414 and hmac-md5 truncated to 96 bits. The mandatory is now
2415 hmac-sha1-96. Rest are optional (including the one that used
2416 to be mandatory). Rationale for this is that the truncated HMAC
2417 length is sufficient from security point of view and can actually
2418 make the attack against the HMAC harder. Also, the truncated
2419 HMAC causes less overhead to the packets. See the RFC2104 for
2422 * Added new [hmac] configuration section. The SKE used to use
2423 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2424 is of course wrong. The official names that must be proposed in
2425 the SKE are the ones defined in the protocol specification
2426 (hmac-sha1-96 for example). The user can configure any hmac
2427 using any hash function configured in the [hash] section. At
2428 least, the mandatory must be configured.
2430 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2432 * Added HMAC list to the SKE proposal list. It has now both
2433 hash algorithm list and HMAC list. This makes the protocol
2434 incompatible with previous versions. The SKE now seems to work
2435 the way it is supposed to work, for the first time actually.
2437 * Defined plain Hash algorithms to the protocol specification.
2440 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Implemented support for key agreement packets into the server.
2443 Added functions silc_server_key_agreement and
2444 silc_server_send_key_agreement. Other than these functions,
2445 server has nothing to do with this packet.
2447 * Added support for private message key packets into the server.
2448 Added functions silc_server_private_message_key and
2449 silc_server_send_private_message_key.
2453 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2454 called in the protocol's final callback instead in the END
2455 protocol state. This makes a little more sense and in the same
2456 time in client we can use the same protocol routines for normal
2457 key exchange and to key agreement packet handling as well.
2459 * Added to both client's and server's KE protocol context the
2460 SilcSKEKeyMaterial pointer to save the key material. We will
2461 bring the key material to the protocol's final callback by doing
2462 this. The final callback must free the key material.
2464 * Added SKE's packet_send callback into client's KE protocol
2465 context so that the caller can choose what packet sending function
2466 is used. This way we can use different packet sending when
2467 doing normal SKE when doing key agreement packet handling (in
2468 the key agreement packet handling we do not want to encrypt
2471 * Implemented the responder side of the key agreement routines
2472 in the client. The client can now bind to specified port and
2473 accept incoming key negotiation. The key material is passed
2474 to the application after the protocol is over.
2476 * Implemented the processing of incoming Key Agreement packet
2477 in the client. Added function silc_client_key_agreement to
2480 * Implemented the intiator side of the key agreement routines
2481 in the client. The client can now initiate key agreement with
2482 another remote client. The key material is passed to the
2483 application after the protocol is over.
2485 * Created client_keyagr.c to include all the key agreement
2488 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2489 SILC_TASK_CALLBACK except that it is not static.
2491 * Created client_notify.c and moved the Notify packet handling
2492 from the client.[ch] into that file.
2494 * Created client_prvmsg.c and moved all private message and
2495 private message key routines from the client.[ch] into that file.
2497 * Create client_channel.c and moved all channel message and
2498 channel private key routines from the client.[ch] into that file.
2500 * Changed silc_client_get_client_by_id_resolve to resolve with
2501 WHOIS command instead of IDENTIFY command, in the file
2502 lib/silclient/idlist.c.
2504 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Implemented the SKE's responder side to the Client library.
2508 * When FAILURE is received to the protocol do not trust it
2509 blindly. Register a timeout to wait whether the remote closes
2510 the connection as it should do it, only after that process the
2511 actual failure. This was changed to both client and server.
2513 * Added client_internal.h to include some of the structures
2514 there instead of client.h in lib/silcclient/.
2516 * Added function silc_task_unregister_by_callback to unregister
2517 timeouts by the callback function.
2519 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Some "Incomplete WHOIS info" errors has been appearing on the
2522 log files. Took away the entry->userinfo check from WHOIS
2523 reply sending. The entry->userinfo is now " " if client did not
2524 provide one. I thought this was fixed earlier but something
2525 is wrong still. Let's see if the error still appears.
2527 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2529 * Fixed a minor bug in the login when the channel key is
2530 re-generated in the server. It used to generate the key in
2531 wrong order and thus caused problems in the channel traffic.
2533 * Fixed a minor bug in channel key distsribution after
2534 KICK command. The key was not sent to the router even though
2537 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Added silc_ske_process_key_material_data as generic routine
2540 to process any key material as the SILC protocol dictates. The
2541 function is used by the actual SKE library but can be used by
2542 applications as well. This relates to the private message keys
2543 and the channel private keys since they must be processed the
2544 same way the normal SILC session keys. The protocol dictates
2545 this. Affected files: lib/silcske/silcske.[ch].
2547 Added also silc_ske_free_key_material to free the
2548 SilcSKEKeyMaterial structure.
2550 * Defined silc_cipher_set_key function to set the key for
2551 cipher without using the object's method function. The affected
2552 files: lib/silccrypt/silccipher.[ch].
2554 * Implemented silc silc_client_add_private_message_key,
2555 silc_client_add_private_message_key_ske,
2556 silc_client_del_private_message_key,
2557 silc_client_list_private_message_keys and
2558 silc_client_free_private_message_keys functions in the
2561 Added functions silc_client_send_private_message_key to send
2562 the Private Message Key payload and silc_client_private_message_key
2563 to handle incoming Private Message Key payload.
2565 * Added Cipher field to the Private Message Key payload to set
2566 the cipher to be used. If ignored, the default cipher defined
2567 in the SILC protocol (aes-256-cbc) is used.
2569 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2571 * Removed lib/silcclient/ops.h file.
2573 Redefined parts of the SILC Client Library API. Created new
2574 file silcapi.h that deprecates the ops.h file and defines the
2575 published Client Library API. Defined also private message key
2576 API and channel private key API into the file.
2578 This is the file that the application must include from the
2579 SILC Client Library. Other files need not be included by
2580 the application anymore.
2582 * Added new key_agreement client operation callback and also
2583 defined the Key Agreement library API for the application.
2585 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2588 is used by clients to request key negotiation between another
2589 client in the SILC network. If the negotiation is started it
2590 is performed using the SKE protocol. The result of the
2591 negotiation, the secret key material, can be used for example
2592 as private message key.
2594 Implemented the Key Agreement payload into the files
2595 lib/silccore/silauth.[ch].
2597 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Redefined ciphers for the SILC protocol. Added some new ciphers
2600 and defined the key lengths for the algorithms. Changed the
2601 code accordingly. The default key length is now 256 bits.
2603 * Fixed SKE key distribution function silc_ske_process_key_material
2604 when the key length is more than 128 bits. The default key
2605 length in SILC is now 256 bits.
2607 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2608 to indicate unsupported algorithm.
2610 * Renamed rijndael.c to aes.c and all functions as well.
2612 * Fixed a long standing channel key setting bug in client library.
2613 Weird that it has never surfaced before.
2615 * Fixed bug in channel deletion. If the entire channel is removed
2616 then it must also delete the references of the channel entry
2617 from the client's channel list as the client's channel entry and
2618 the channel's client entry share same memory.
2620 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * Implemented CONNECT and SHUTDOWN commands in the client.
2624 * Implemented CLOSE command to the client.
2626 * Added the function silc_idlist_find_server_by_name into the
2627 files silcd/idlist.[ch].
2629 Added the function silc_idlist_find_server_by_conn into the
2630 files silcd/idlist.[ch].
2632 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * DIE command was renamed to SHUTDOWN. Updated the both code
2637 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2638 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2640 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2643 * Added function silc_server_create_connection function to create
2644 connection to remote router. My server implementation actually
2645 does not allow router to connect to normal server (it expects
2646 that normal server always initiates the connection to the router)
2647 so the CONNECT command is only good for connecting to another
2650 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2653 or some other client was kicked from the channel.
2655 Implemented the handling of the notify type to both client
2658 Implemented silc_server_send_notify_kicked to send the KICKED
2659 notify. It is used to send it to the server's primary router.
2661 * Implemented the KICK command into server and client.
2663 * Added `query' argument to the silc_idlist_get_client function
2664 to indicate whether to query the client from server or not if
2667 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2668 to indicate that the client is not channel founder.
2672 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2674 * Removed the rng context from SilcPacketContext structure and
2675 changed that the packet routine uses the Global RNG API.
2677 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Added support for quit message that client can "leave" on the
2680 channel when it quits the SILC. It is ditributed inside the
2681 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2683 Added silc_server_free_client_data that will take the
2684 signoff message as argument.
2686 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2688 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2690 * Updated parts of the protocol specification to keep it up
2693 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2695 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2696 payloads in one packet.
2698 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2699 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2700 use now the new List flag.
2702 * Also deprecated the following packet types: REPLACE_ID,
2703 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2705 * Added list support for Notify packet in server.
2707 * Added silc_server_send_notify_channel_change to send the
2708 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2709 the silc_server_send_replace_id.
2711 * Added silc_server_send_notify_nick_change to send the
2712 NICK_CHANGE notify type. Deprecates the function
2713 silc_server_send_replace_id.
2715 * Added silc_server_send_notify_join to send the JOIN notify type.
2716 Deprecates the function silc_server_send_new_channel_user.
2718 * Added silc_server_send_notify_leave to send LEAVE notify type.
2719 Deprecates the function silc_server_send_remove_channel_user.
2721 * Added silc_server_send_notify_cmode and
2722 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2723 types. Deprecates the silc_server_send_set_mode function.
2725 * Added SERVER_SIGNOFF notify type to indicate that server has
2726 quit. This means that all clients on the channel from that
2727 server will drop. This can be also used when netsplit happens.
2729 Deprecated REMOVE_ID packet type since it is not needed anymore
2732 Added silc_server_send_notify_server_signoff to send the
2733 SERVER_SIGNOFF notify type. Deprecates the function
2734 silc_server_send_remove_id.
2736 Added also silc_server_send_notify_signoff to send the
2737 SIGNOFF notify type.
2739 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2740 SILC protocol from this day on. Changed the protocol
2741 specification as well.
2743 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2744 notify type. It is used between routers to notify about
2745 topic changes on a channel.
2747 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2750 * Partly updated the protocol specification to comply with the
2751 changes now made. It is still though a bit outdated.
2753 * The JOIN notify type now takes one extra argument <Channel ID>.
2754 The packet used to be destined to the channel but now the
2755 JOIN type may be sent as list thus it is impossible to
2756 destine it to any specific channel. By adding this argument
2757 it is again possible.
2759 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * Added CREDITS file. The CHANGES and CREDITS file will appear
2762 in the distribution as well.
2764 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2767 types in the server's silcd/packet_receive.c.
2769 * Implemented CMODE and CUMODE to work in router environment.
2771 * Fixed minor encoding and decoding buglet from the
2772 lib/silccore/silcmode.c.
2774 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2777 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2779 * Changed all SilcConfigServer* and silc_config_server* to
2780 SilcServerConfig* and silc_server_config*, respectively.
2783 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2785 * Associated the ID (client or server ID) to the Authentication
2786 Payload to avoid any possibility of forging. Updated the
2787 protocol specification and the code accordingly.
2789 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * The RSA key length is now save to the RsaKey context in the
2792 key generation process in lib/silccrypt/rsa.c. The key length
2793 is now used to figure out the maximum size of the block allowed
2794 to be encrypted/signed.
2796 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2797 is equivalent to the silc_mp_mp2bin but does not allocate any
2800 * Changed silc_mp_mp2bin API to take length argument. If it is
2801 non-zero then the buffer is allocated that large. If zero, then
2802 the size is approximated using silc_mp_sizeinbase, which however
2805 * Created Global RNG API which is global RNG that application can
2806 initialize. After initializing, any routine anywhere in the
2807 code (including library) can use RNG without allocating a new
2808 RNG object. This was done to allow this sort of use of the
2809 RNG in code that has no chance to allocate RNG object. All
2810 applications currently allocate this and many routines in the
2811 library use this. Affected file lib/silccrypt/silcrng.[ch].
2813 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2814 it to use the Global RNG API.
2816 * Defined Authentication Payload into protocol specification that
2817 is used during SILC session to authenticate entities. It is
2818 used for example by client to authenticate itself to the server
2819 to obtain server operator privileges.
2821 Implemented this payload into the lib/silccore/silcauth.[ch].
2822 Implemented also routines for public key based authentication
2823 as the new protocol specification dictates.
2825 Moved definitions of different authentication methods from
2826 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2828 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2829 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2830 silc_pkcs_verify_with_hash functions into the file
2831 lib/silccrypt/silcpkcs.[ch].
2833 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * The client entry's userinfo pointer must be always valid.
2836 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2837 will fail since it requires the userinfo. Now, the userinfo
2838 is allocated as "" if actual userinfo does not exist. Actually,
2839 it must exist and it is totally Ok to drop client connections
2840 that does not announce the userinfo. However, we will make
2841 this workaround for now.
2843 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2844 to return the remote port by socket.
2846 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2849 SILC_SERVER_PENDING_EXEC and added an new macro
2850 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2851 data or when error occurs while processing the pending command.
2853 Added new argument `destructor' into silc_server_command_pending
2854 and to the SilcServerCommandPending object. This destructor is
2855 now called after calling the pending callback or if error occurs
2856 immediately. If error occurs the actual pending callback won't
2857 be called at all - only the destructor. The destructor may be
2858 NULL if destructor is not needed.
2860 All this applies for client library code as well. Similar
2861 changes were made there as well for the pending commands.
2863 In the client, the application must now allocate the
2864 SilcClientCommandContext with the silc_client_command_alloc
2867 * Added reference counter to the SilcServerCommandContext. Added
2868 function silc_server_command_alloc and silc_server_command_dup
2871 Same type of functions added to the client library for the same
2874 * Removed the cmd_ident from IDListData away since it is now
2875 global for all connections. It is the command identifier used
2876 in command sending and with pending commands. The affected file
2879 * Added reference counter to the SilcSocketConnection objecet to
2880 indicate the usage count of the object. The object won't be
2881 freed untill the reference counter hits zero. Currently only
2882 server uses this, and client ignores it. The client must be
2883 set to use this too later. The affected files are
2884 lib/silccore/silcsockconn.[ch]. Added also the function
2885 silc_socket_dup to increase the reference counter.
2887 This was mainly added because it is possible that the socket
2888 is removed underneath of pending command or other async
2889 operation. Now it won't be free'd and proper DISCONNECTING
2890 flags, etc. can be set to avoid sending data to connection that
2891 is not valid anymore.
2893 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2894 the connection. After that it sets SILC_SET_DISCONNECTED.
2895 It is, however, possible that the socket data is not still freed.
2896 The silc_server_packet_process now checks that data is not
2897 read or written to connection that is DISCONNECTED. The socket
2898 get's freed when the reference counter hits zero.
2900 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Changed the client operation API: channel_message operation's
2903 `sender' is now the client entry of the sender, not the nickname
2904 and the `channel' is the channel entry, not the channel name.
2906 In the private_message operation the `sender' is now also the
2907 client entry of the sender not the nickname.
2909 Affected file is lib/silcclient/ops.h and all applications
2910 using the client operations.
2912 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Moved the calling of ops->connect() from connect_to_server_final
2915 into receive_new_id functin since that is the point when the
2916 client is actually allowed to send traffic to network. The
2917 affected file is lib/silcclient/client.c.
2919 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2922 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2923 (if needs broadcasting) instead of broadcasting the packets one
2924 by one which would make a burst in the network traffic.
2926 * Added `broadcast' argument to the functions in silcd/server.[ch]
2927 silc_server_create_new_channel[_with_id] to indicate whether
2928 to send New Channel packet to primary router.
2930 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Added new function into the silcd/server.[ch] files:
2933 silc_server_create_new_channel_with_id to create new channel with
2934 already existing Channel ID.
2936 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2937 lib/silccore/silcpacket.h. This packet is used t send list of
2938 Set Mode payloads inside one packet. Server uses this to set
2939 the modes for the channels and clients on those channels, that it
2940 announced to the router when it connected to it. The protocol
2941 specification has been updated accordingly.
2943 * The silc_server_new_channel did not handle the packet coming
2944 from normal server as it normally does not send that. However,
2945 when it announces its channels it does send it. Implemented
2946 the support for that.
2948 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2949 into the file lib/silccore/id.h.
2951 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Fixed memory leaks in the functions silc_idlist_del_client,
2954 silc_idlist_del_channel and silc_idlist_del_server in the file
2955 silcd/idlist.c. All of those leaked like a sieve.
2957 * Fixed some small memory leaks in the client's function
2958 silc_client_notify_by_server.
2960 * Added functions into silcd/server.c: silc_server_announce_clients,
2961 silc_server_announce_channels and silc_server_announce_server.
2962 These functions are used by normal and router server to announce
2963 to its primary router about clients, channels and servers (when
2964 router) that we own. This is done after we've connected to the
2967 These functions effectively implements the following packet types:
2968 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2969 and SILC_PACKET_NEW_ID_LIST.
2971 * Added new functions into the silcd/packet_receive.[ch]:
2972 silc_server_new_id_list, silc_server_new_channel_list and
2973 silc_server_new_channel_user_list to handle the incoming
2974 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2976 * Added support of changing Channel ID in the function
2977 silc_server_replace_id. If the server that announces a channel
2978 to the router already exists in the router (with same name but
2979 with different Channel ID), router is responsible to send
2980 Replace ID packet to the server and force the server to change
2981 the Channel ID to the one router has.
2983 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2984 client that the Channel ID has been changed by the router. The
2985 normal server sends this to the client. Client must start using
2986 the new Channel ID as the channel's ID.
2988 Implemented handling of this new type into lib/silcclient/client.c
2989 into the function silc_client_notify_by_server.
2991 * Added new function silc_idlist_replace_channel_id into the files
2992 silcd/idlist.[ch] to replace the Channel ID.
2994 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Call silc_server_command_identify_check always when processing
2997 the IDENTIFY command in silcd/command.c
2999 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3002 send keepalive packets. The packet can be sent by clients,
3003 servers and routers.
3005 Added function silc_socket_set_heartbeat into the file
3006 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3007 If not set, the heartbeat is not performed. The actual
3008 heartbeat is implemented in the low level socket connection
3009 library. However, application is responsible of actually
3012 Added silc_server_send_heartbeat to send the actual heartbeat
3013 packet into silcd/packet_send.[ch]. Server now performs
3014 keepalive with all connections.
3016 * Added silc_task_get_first function into lib/silcutil/silctask.c
3017 to return the timeout task with shortest timeout. There was a bug
3018 in task unregistration that caused problems. TODO has been
3019 updated to include that task system must be rewritten.
3021 * The client library will now resolve the client information when
3022 receiving JOIN notify from server for client that we know but
3023 have incomplete information.
3025 * Rewrote parts of silc_server_remove_from_channels and
3026 silc_server_remove_from_one_channel as they did not remove the
3027 channel in some circumstances even though they should've.
3029 * Encryption problem encountered in server:
3031 The LEAVE command used to send the Channel Key packet to the
3032 router immediately after generating it. However, the code
3033 had earlier sent Remove Channel user packet but not immediately,
3034 ie. it was put to queue. The order of packets in the router
3035 was that Channel Key packet was first and Remove Channel User
3036 packet was second, even though they were encrypted in the
3037 reverse order. For this reason, MAC check failed. Now, this
3038 is fixed by not sending the Channel Key packet immediately but
3039 putting it to queue. However, this is more fundamental problem:
3040 packets that are in queue should actually not be encrypted
3041 because packets that are sent immediately gets encrypted
3042 actually with wrong IV (and thus MAC check fails). So, packets
3043 that are in queue should be encrypted when they are sent to
3044 the wire and not when they put to the queue.
3046 However, the problem is that the current system has not been
3047 designed to work that way. Instead, the packet is encrypted
3048 as soon as possible and left to the queue. The queue is then
3049 just purged into wire. There won't be any fixes for this
3050 any time soon. So, the current semantic for packet sending
3053 o If you send packet to remote host and do not force the send
3054 (the packet will be in queue) then all subsequent packets to the
3055 same remote host must also be put to the queue. Only after the
3056 queue has been purged is it safe again to force the packet
3059 o If you send all packets immediately then it safe to send
3060 any of subsequent packets through the queue, however, after
3061 the first packet is put to queue then any subsequent packets
3062 must also be put to the queue.
3064 Follow these rules and everything works fine.
3066 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Added new function silc_server_remove_clients_by_server to
3069 remove all client entries from ID list when the server connection
3070 is lost. In this case it is also important to invalidate all
3071 client entires as they hold the invalid server entry. This
3072 fixes fatal bug when server has lost connection and will reconnect
3075 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Made some sanity checks to silc_server_daemonise like to check
3078 whether the requested user and group actually exists.
3080 * Added sanity check to SKE's silc_ske_responder_finish to check
3081 that the public and private key actually is valid.
3083 * Invalidate the client's nickname when receiving Replace ID
3084 packet and the Client ID is being replaced. This means that the
3085 server will query the nickname if someone needs it (client)
3088 * Sort the ID Cache in client library when the ID Cache data
3089 has changed (needs sorting).
3091 * Do not allow for SILC client to create several connections to
3092 several servers. The client does not support windows right now
3093 and generating multiple connections causes weird behaviour.
3095 Irssi-silc client does support windows and can handle several
3096 connections without problems, see: www.irssi.org and SILC plugin.
3098 * Fixed some places where client was added to the IDList. The
3099 rule of thumb is following (in order to get everything right):
3100 If the client is directly connected local client then the
3101 `connection' argument must be set and `router' argument must be
3102 NULL to silc_idlist_add_client function. If the client is not
3103 directly connected client then the `router' argument must
3104 bet set and the `connection' argument must be NULL to the
3105 silc_idlist_add_client function.
3107 * The funtion silc_server_packet_send_local_channel actually did
3108 not check whether the client was locally connected or not. It
3109 does that now. Fixed a bug related to LEAVE command.
3111 * Fixed Remove Channel User payload parsing bug in server's
3112 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3114 * The server's silc_server_save_channel_key now checks also the
3115 global ID list for the channel as it might not be in the local
3116 list. Fixed a bug related to LEAVE command.
3118 * Is this the end of the [<unknown>] buglet that has been lurking
3119 around for a long time? A little for loop fix in server's
3120 silc_server_command_whois_parse that is used by both IDENTIFY
3121 and WHOIS command. At least, this was a clear bug and a cause
3122 of one type of [<unknown>] buglet.
3124 * WHOIS and IDENTIFY commands call the function
3125 silc_server_command_[whois/identify]_check function even if
3126 we are not router server.
3128 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Added --with-gmp configuration option. If set the GMP
3131 is always compiled in the SILC source tree. If not set then
3132 it is checked whether the system has the GMP3 installed. If
3133 it has then the GMP won't be compiled (the system's headers
3134 and library is used), if it doesn't have it then the GMP is
3135 compiled in the SILC source tree.
3137 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Changed RSA private exponent generation to what PKCS #1
3140 suggests. We try to find the smallest possible d by doing
3141 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3142 not security fix but optimization.
3144 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Added new config entry [Identity] to fork the server and run
3147 it as specific user and group. A patch from Bostik.
3149 * Imported Dotconf configuration library into lib/dotconf.
3150 This will be used to create the SILC configuration files later.
3151 It will appear in the distsribution after this commit.
3153 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * A big code auditing weekend happening. Auditing code for
3156 obvious mistakes, bugs and errors. Also, removing any code
3159 Removed files for being obsolete:
3161 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3162 inline in the file lib/silcutil/silcbuffer.h)
3164 o lib/silcutil/silcbufutil.c (the header has inline versions)
3166 Changed code to fix possible error conditions:
3168 o The buffer formatting routines now check that the destination
3169 buffer really has enough space to add the data. This applies for
3170 both buffer formatting and unformatting
3171 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3172 unformatting was changed to accomodate following rules:
3173 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3174 sent to the function while XXX_*STRING will not allocate or copy
3175 the data into the buffer. Instead it sets the pointer from the
3176 buffer into the pointer sent as argument (XXX_*STRING used to
3177 require that the pointer must be allocated already). This change
3178 makes this whole thing a bit more consistent and more optimized
3179 (note that the data returned in the unformatting with XXX_*STRING
3180 must not be freed now). The routines return now -1 on error.
3182 o Tried to find all code that use buffer_format and buffer_unformat
3183 and added return value checking to prevent formatting and
3184 especially unformatting errors and possible subsequent fatal
3187 o Changed ske->x and ske->KEY to mallocated pointers in
3188 lib/silcske/silcske.h. Fixed possible data and memory leak.
3190 o Added return value checking to all *_parse* functions. Fixed
3191 many memory leaks as well.
3193 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3194 so that buffer overflows would not happen. All code now also
3195 checks the return value as it can fail.
3197 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Added reconnection support to server if the normal server looses
3200 its connection to the router (for example if router is rebooted).
3201 The server performs normal reconnection strategy implemented
3202 to the server. Affected file silcd/server.c.
3204 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added new packet type SILC_PACKET_SET_MODE that is used to
3207 distribute the information about changed modes (for clients,
3208 channels and clients channel modes) to all routers in the
3209 network. Updated the protocol specification accordingly.
3211 Added functions into silcd/packet_send.c and
3212 silcd/packet_receive.c: silc_server_send_set_mode,
3213 silc_server_set_mode.
3215 Added new files silcmode.[ch] into lib/silccore that implements
3216 the encoding and decoding of Set Mode Payload. Added new type
3217 SilcSetModePayload. Moved the definitions of different modes
3218 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3220 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Oops, a little mistake in server's connection authentication
3223 protocol. The protocol is not ended with FAILURE but with
3224 SUCCESS if the authentication is Ok. :) Affected file is
3227 * Implemented NICK_CHANGE notify handling in server in the file
3228 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3229 the local clients on the channel. After the changing nickname
3230 in router environment snhould work and the [<unknown>] nickname
3231 should appear no more.
3233 The silc_server_replace_id function that receives the Replace ID
3234 payload now sends the NICK_CHANGE notify type also in the file
3235 silcd/packet_receive.c
3237 * Changed WHOIS and IDENTIFY command to support the maximum amount
3238 of arguments defined in protocol specs (3328 arguments). This
3239 fixed a bug that caused problems when there were more than three
3242 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Added extra parameter, command identifier, to the
3245 silc_client_send_command so that explicit command identifier
3248 Changed that ID list routines uses specific command identifier
3249 when sending WHOIS/IDENTIFY requests to the server so that they
3250 can be identified when the reply comes back.
3252 Affected files lib/silcclient/command.[ch],
3253 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3255 * Added `sender' argument to silc_server_packet_send_to_channel
3256 to indicaet the sender who originally sent the packet to us
3257 that we are now re-sending. Ignored if NULL. Affected file
3258 silcd/packet_send.[ch].
3260 * Added some server statistics support in silcd/server_internal.h
3261 SilcServerStatistics structure and around the server code. Also
3262 send some nice statistics information when client is connecting
3265 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Fixed channel ID decoding in server's JOIN command reply in
3268 silcd/command_reply.c
3270 * Fixed braodcasting of replace ID payload to not to send it if
3271 we are standalone server in silcd/packet_receive.c.
3273 * Fixed all channel message sending routines to not to send
3274 packets to clients that has router set, since they are routed
3275 separately in the same function earlier. Affects file
3276 silcd/packet_send.c and all channel packet sending functions.
3278 * In USERS reply, res_argv[i] are not allocated, the table
3279 is allocated. Thus changed that free the table, not its
3282 * In server's whois_check and identify_check if the client is
3283 locally connected do not send any WHOIS commands - they are not
3286 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Fixed some minor bugs in client when sending WHOIS command. The
3289 arguments was in wrong order.
3291 * Removed statis function add_to_channel from server in
3292 silcd/command.c that was previously used with the joining but
3295 * Tested USERS command in router environment successfully with two
3296 routers, two servers and two clients.
3298 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Reorganized the USERS command and command reply in client library
3301 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3302 When the command is given by user we register a pending command
3303 callback that will reprocess the command after the reply has been
3304 received from the server. When reprocessing the packet we then
3305 display the information. Thus, the USERS information is displayed
3306 now in the command callback instead of in the command reply
3307 callback. The processing of the command is same as previously
3308 when server has sent the command reply in the JOINing process.
3310 * Added to USERS command in silcd/command_reply.c to join the client,
3311 we didn't use to know about, to the channel after we've created
3312 a client entry for it. Also, for clienet we did know already still
3313 check whether it is on the channel or not and add it if not.
3315 * Removed silc_server_command_join_notify as the function and its
3318 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Changed the client's pending command handling to the same as the
3321 server's pending command handling. It is also now possible to
3322 execute command reply functions from other command reply
3323 function as the function callbacks for commands and command
3324 replies are one and same. The pending commands are not static
3325 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3326 in client connection context. Thus, pending commands are server
3327 connection specific as it is convenient.
3329 Changed the function silc_client_command_pending and
3330 silc_client_command_pending_del and added new function
3331 silc_client_command_pending_check. Removed the
3332 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3335 * Added cmd_ident, current command identifier, to the client
3336 connection context in lib/silcclient/client.h to keep track on
3337 command identifiers used in command sending. Client's command reply
3338 function handling now supports the mandatory command identifiers.
3340 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3341 funtions in client to fully support pending command callbacks.
3343 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3344 as one of the arguments to the application in the command reply
3347 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3348 before first releasing SILC but came back. Now it is removed again
3349 and should come back nomore. The FORWARDED flag was used only
3350 by the JOINing procedure by forwarding the command packet to router.
3351 Now, the JOINing procedure has been changed to more generic (due
3352 to various router environment issues) and FORWARDED is not needed
3353 anymore for anything. The protocol specification is yet to be
3356 Now, removed silc_server_packet_forward from server and the flag
3357 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3359 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Renamed NAMES command to USERS command. The NAMES was named that
3362 due to historical reasons. Now it is renamed. Also, rewrote
3363 parts of the USERS command. The nickname list is not sent anymore
3364 by the server. Only Client ID and mode lists are sent in the USERS
3365 command. Changed this also to the protocol specification.
3367 The client now resolves the names and stuff after it receives
3368 the USERS list from the server when joining to the channel.
3370 * WHOIS and IDENTIFY commands has been changed to support multiple
3371 Client ID's per command. One can now search for multiple users
3372 in the network by sending only one WHOIS or IDENTIFY command.
3373 Changed the code and the protocol specifications.
3375 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3376 uses silc_server_command_whois_parse to parse the request. */
3378 * If normal server, do not parse the WHOIS and IDENTIFY requests
3379 before sending it to the router. Saves some time.
3381 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Fixed JOIN command on client library. Wrong number of arguments
3384 used to crash the client.
3386 * Added silc_server_channel_has_global function to check whether
3387 channel has global users or not.
3389 * Added silc_server_channel_has_local function to check whether channel
3390 has locally connected clients on the channel.
3392 * The silc_server_remove_from_one_channel now checks whether the
3393 channel has global users or not after given client was removed from
3394 the channel. It also checks whether the channel has local clients
3395 on the channel anymore. If it does not have then the channel entry
3396 is removed as it is not needed anymore.
3398 * The silc_server_notify now checks on JOIN notify whether the joining
3399 client is one of locally connected or global. If it is global then
3400 the channel has now global users on the channel and that is marked
3401 to the channel entry. Also, it now saves the global client to
3402 global list who is joining and JOINs it to the channel. This is
3403 for normal server, that is.
3405 Changed silc_server_send_notify_on_channel,
3406 silc_server_packet_relay_to_channel and
3407 silc_server_packet_send_to_channel check if we are normal server
3408 and client has router set (ie. global client) do not send the
3409 message to that client, as it is already routed to our router.
3411 * Implemented LEAVE notify type handling in silc_server_notify
3414 * Tested LEAVE command in router environment successfully. Tested
3415 with two routers, two servers and two clients.
3419 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3421 * Implemented SIGNOFF notify type handling in silc_server_notify
3424 * silc_server_remove_id now removes the client entry from all channels
3425 it has joined and thusly sends SIGNOFF notify type.
3427 * Rewrote the NAMES list generation in server by removing two excess
3428 loops. The lists are created now inside one loop.
3430 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * silc_server_remove_channel_user checks now also global list
3433 for channel and client.
3435 * silc_server_new_channel_user checks now both local and global
3436 list for channel and client. Fixed a bug in client id decoding.
3437 Used to decode wrong buffer.
3439 * silc_server_channel_message checks now both local and global
3440 list for channel entry.
3442 * Tested channel joining (hence JOIN) in router environment
3443 successfully. Tested with two routers, two servers and two
3446 * Tested channel message sending in router environment successfully.
3448 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * Added silc_server_save_channel_key into server.[ch] to save the
3451 received channel key in Channel Key payload processing. It is
3452 also used in JOIN command reply handling.
3454 Equivalent function silc_client_save_channel_key added into
3455 client.[ch] into client library.
3457 * Changed JOIN command reply to send information whether the channel
3458 was created or not (is existing already) and the channel key
3459 payload. Changed protocol specs accordingly.
3461 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3462 the request was sent by ID and not by nickname. Crashed on
3465 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3468 now correctly save the received data.
3470 * silc_server_free_sock_user_data now notifies routers in the
3471 network about entities leaving the network.
3473 At the same time implemented functions silc_server_remove_id
3474 and silc_server_send_remove_id to receive and send REMOVE_ID
3475 packets. The packet is used to notify routers in the network
3476 about leaving entities. The ID removed will become invalid in
3479 * Added function silc_idlist_del_server into server. Removes and
3480 free's server entry from ID list.
3482 * silc_server_private_message function now checks, if we are router,
3483 that the destination ID really is valid ID, naturally.
3485 * In router when NEW_ID packet is received (for new client) the
3486 hash of the Client ID is saved in the ID Cache but the
3487 client->nickname is set to NULL, instead of putting the hash
3490 IDENTIFY command now also checks that client->nickname must be
3491 valid. If it is not if will request the data from the server who
3492 owns the client. Added new function
3493 silc_server_command_identify_check.
3495 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3496 to set the command to already allocated Command Payload.
3498 * Tested private message sending in router environment with two
3499 routers, two servers and two clients. Fixed minor bugs and now
3502 * Fixed segfault from client's NAMES command. Used to crash if
3505 * Forwarded packets must not be routed even if it is not destined
3506 to the receiver. Changed server code comply with this.
3508 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added `require_reverse_mapping' boolean value to ServerParams
3511 structure. If TRUE (not default) the server will require that
3512 the connecting host has fully qualified domain name.
3514 If the reverse mapping is not required and hostname could not be
3515 found the IP address is used as hostname.
3517 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Implemented version string checking to both client and server.
3520 The check is incomplete currently due to the abnormal version
3521 strings used in development version of SILC.
3523 * Changed all command functions in server to use the new
3526 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Changed char *data to unsigned char *data in ID Cache system to
3529 support binary data as ID Cache data. Changed code to support
3530 binary data in lib/silccore/idcache.c.
3532 * Renamed silc_server_packet_relay_command_reply to
3533 silc_server_command_reply as it is normal packet receiving
3534 function. Rewrote the function to accept command replys for
3535 servers and not only for clients.
3537 * Mark remote router always as registered server if we are connecting
3538 to it. Otherwise, commands sent by the router to us are ignored.
3540 * All ID List find routines now returns the ID Cache Entry pointer
3541 as well if requested.
3543 * WHOIS command works now in router environment, tested with two
3544 routers, two servers and two clients.
3546 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3547 in router environment (as it is almost equivalent to WHOIS) but
3548 hasn't been tested thoroughly. Added new functions:
3550 silc_server_command_identify_parse
3551 silc_server_command_identify_send_reply
3552 silc_server_command_identify_from_client
3553 silc_server_command_identify_from_server
3555 * Disabled route cache adding because adding two different ID's with
3556 same IP replaces the old cache entry thus giving wrong route.
3557 The entry->router->connection is always the fastest route anyway
3558 so route cache may not be needed. Of course, new routes maybe
3559 established after receiving the ID when the entry->router->connection
3560 might not be anymore the most optimal.
3562 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Add route cache for received ID for fast routing.
3566 * Added silc_server_packet_route to route received packet on router
3567 that is not destined to us.
3569 * Renamed silc_server_get_route to silc_server_route_get.
3571 * Added id_string and id_string_len fields into SilcServer to
3572 include encoded ServerID for fast comparing without excess
3573 encoding of the ID's.
3575 * Cleaned up WHOIS command on server side. Added following static
3578 silc_server_command_whois_parse
3579 silc_server_command_whois_check
3580 silc_server_command_whois_send_reply
3581 silc_server_command_whois_from_client
3582 silc_server_command_whois_from_server
3584 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3585 arguments in command replies. All command functions should be
3586 updated to use this macro.
3588 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Minor typo fixes on command reply handling on server.
3592 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Added silc_server_command_add_to_channel internal routine to add
3595 the client to the channel after router has created the channel and
3596 sent command reply to the server.
3598 * Added generic silc_server_send_command to send any command from
3601 * Use static buffer with ID rendering instead of duplicating data.
3603 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Fixed a channel user mode bug when joining to a channel server gave
3606 everybody channel founder rights, oops.
3608 * We mark ourselves as the router of the incoming server connection
3609 if we are router ourselves. This way we can check in some packet
3610 sending functions whether it is locally connected server. For
3611 incoming router connections we put NULL.
3613 * For router sending packets locally means now always sending the
3614 packet cell wide; to local clients and local servers. For normal
3615 server sending packet locally means sending it to only local
3618 * Fixed the JOIN command to really work in router environment. If the
3619 channel is created it is always created by the router. Router is
3620 also responsible of making the initial joining to the channel,
3621 sending JOIN notify to the sending server and distributing
3622 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3623 does not exist server doesn't do anything else but forward the
3624 command to the router which performs everything.
3626 * Added silc_server_send_channel_key function to send the Channel Key
3629 * Added silc_server_create_channel_key to create new channel key. The
3630 channel key is now re-generated everytime someone joins or leaves
3631 a channel, as protocol dictates. Note: channel->key_len is the
3634 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3637 packet_receive.[ch] to separate packet sending and receiving
3638 routines. The server.[ch] now includes everything else including
3639 actual packet processing (writing and reading data) and other
3642 Renamed silc_server_private_message_send_internal to
3643 silc_server_send_private_message. The routine is still though
3644 used only to relay private messages as server does not send
3645 private messages itself.
3647 Renamed silc_server_new_channel to silc_server_create_new_channel
3648 and added new function sicl_server_new_channel that handles the
3649 incoming New Channel packet. Added also new sending function
3650 silc_server_send_new_channel to send New Channel Payload.
3652 * Added new function silc_server_notify to process incoming notify
3653 packet to the server/router. Server may then relay the notify
3654 to clients if needed.
3656 * Added new function silc_server_new_channel_user to process incoming
3657 New Channel User packet. Router will redistribute the packet and
3658 send JOIN notify to its local clients and locally connected servers
3659 if needed. Normal server will send JOIN notify to its local client
3660 on same channel when received this packet. Added also corresponding
3661 sending function silc_server_send_new_channel_user to sent the
3664 * Added boolean route argument to send_notif_to_channel and
3665 packet_send_to_channel functions to attempt to route the packet
3666 if it is TRUE and send only locally if it is FALSE.
3668 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * silc_server_replace_id now broadcasts the received replace ID
3671 packet if it is not broadcast packet already. The router must
3672 broadcast to inform other routers about changed ID.
3674 * Added backpointer to server's router into SilcServer context in
3675 silcd/server_internal.h.
3677 * Fixed silc_server_packet_broadcast to send correct broadcast
3680 * The channel key is now distributed to the local client as soon
3681 as it is received from the router (in router environment) so that
3682 no other packet may be sent for the channel until client has
3685 * silc_server_remove_channel_user now broadcasts the received
3686 Remove Channel User packet if it is not broadcast packet already.
3687 The router must broadcast to inform other routers about removed
3690 * Added users field into SilcPacketContext that is a reference count
3691 of the context. One can increase the reference count by calling
3692 silc_packet_context_dup which is now changed to just increase the
3693 reference count instead of duplicating the data. The reference
3694 count is decresed by calling silc_packet_context_free that will
3695 free the data after the reference count hits zero.
3697 For now on the packet context and everything allocated into it
3698 (including the raw packet from network) must be freed by calling
3699 the new silc_packet_context_free function. Added also new function
3700 silc_packet_context_alloc that must be used now to allocate the
3701 context. This also means that if a routine is asynchronous from
3702 silc_[client/server]_packet_parse_type the packet context must
3703 be duplicated by calling silc_packet_context_dup. Otherwise it
3704 gets free'd after silc_[client/server]_packet_parse_type returns.
3705 Also, one must remember that if packet is duplicated then its
3706 reference count must be decresed by calling the free function as
3707 many times as it was duplicated.
3709 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3710 from both client and server.
3712 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Made joining to a channel working in router environment.
3716 * Cleaned up JOIN command on server side and create function
3717 silc_server_command_join_channel internal routine to make the
3720 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Changed silc_command_pending list to SilcDList. Also, added
3723 `ident' field to SilcServerCommandPending structure to identify
3724 the reply and to call correct callback.
3726 Added silc_server_command_pending_check function to replace the
3727 corresnponding macro. The silc_command_pending list is not
3730 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3731 to set identifier to previously allocated Command Payload. It
3732 is used to set identifier for command when resending Command
3735 * Added silc_command_payload_encode_payload to encode Command
3736 Payload buffer from SilcCommandPayload structure.
3738 * Added silc_argument_payload_encode_payload to encode Argument
3739 payload buffer from SilcArgumentPayload structure.
3741 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Changed WHOIS command to support router connection on server side.
3744 The whois request is always sent to router unless the server is
3745 standalone server. After server has received the reply from the
3746 router will it send the reply to the client.
3748 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3749 broadcast received broadcast packet. The function is used only
3750 by router. The broadcast packet is always sent to the router's
3753 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3754 render given ID to printable string, for log files for example.
3756 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Made basic router to router connections working. At least they
3759 can now connect to each other but nothing really works the way
3760 they are supposed - yet.
3762 * Added new initiator token to RouterConnection configuration
3763 file in silcd/serverconfig.[ch]. It is used to tell whether we
3764 are the initiator to the remote router or whether we'll expect
3765 the other end to connect.
3767 * Moved registering of listener task to silc_server_init, hence
3768 the server starts listenning as soon as it is run, even if it
3769 does not have connections to other routers. Let's see how well
3772 * Changed default connection retry timeouts for more suitable in
3775 * Removed cipher and such arguments from silc_idlist_add_client
3776 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3777 Added new function silc_idlist_add_data to add the keys and stuff
3780 * Added SilcIDListData structure and added it to SilcClientEntry
3781 and SilcServerEntry as their first field in the structure. This
3782 way we can explicitly cast the ID entries to the SilcIDListData
3783 structure and get common data for the entries. In past, we had
3784 to first check what type of connection it is and then cast it to
3785 correct ID entry type. Now, we can directly cast the opaque
3786 pointer to the SilcIDListData (no matter what ID entry it actually
3787 is) and get the data needed.
3789 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3792 in some circumstances even if threre were timeout tasks, though not
3793 IO tasks, but tasks anyway. Now fixed.
3795 * Defined SilcServerConnection structure to hold connection specific
3796 stuff about directly connected servers and routers. The definition
3797 is currently in silcd/server_internal.h. I thought about having
3798 a bit more important role fro this struct but for now it is used
3799 only when connecting to other server (or router actually).
3801 * Added connecting retry support in server when connecting to
3802 router(s). The retry feature implement exponential backoff
3803 algorithm. Also, added SilcServerParams structure to hold default
3804 parameters for server. For now, it include these retry settings
3805 and are hard coded. After server is moded to be as Silc Server
3806 Library this structure will be more important.
3808 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Changed client librarys channel->clients table to SilcList and
3811 changed code accordingly.
3813 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Changed client's channel table to SilcList and changed code
3816 accordingly. Also changed SilcChannelClientEntry to include back-
3817 pointer to the channel so that client entry can use that structure
3818 as list as well and we have fast cross-reference to the channel.
3819 This change dramatically decreased the complexity of channel
3820 handling with client entry and vice versa (removed one extra
3821 loop when searching for channel entry from many functions).
3823 * Changed server->sim from table to SilcDList and changed code
3826 * NAMES command can now be used from user interface. It will show
3827 the user list on the channel, neatly.
3829 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3830 Code now saves realname of the user if it becomes available.
3832 * Renamed configure.in to configure.in.pre and made ./prepare
3833 script to automatically add correct version string to
3834 configure.in which it creates from configure.in.pre.
3836 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * NAMES command reply now shows users mode with the nickname when
3841 * Moved silc_client_ch[u]mode[_char] functions from
3842 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3843 place sucks, they are utility functions and should be in some
3846 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3848 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3851 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * Added TRQ (efficient deque and list library) into lib/trq. This is
3856 a very good list library that is currently used in the SILC. Defined
3857 SilcList API over the library because I didn't like the API very
3858 much. See lib/trq/silclist.h for the API and examples of how to
3859 use the API. Fixed various places in the code to use the new
3860 SilcList API. The SilcList is meant for lists that has a structure
3861 already defined as a list. It is not suitable to add just some
3862 context to the list (in TRQ, the context is the list actually).
3864 So, I defined SilcDList that can be used for the purpose where
3865 predefined list structure does not exit. This can be used as
3866 such list. Now some context just can be added to the SilcDList.
3867 Currently this list is not used in the SILC just yet, though there
3868 are a lot places where this can replace dynamically allocated
3869 tables and I will fix these places, later, to use SilcDList.
3870 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3871 and use TRQ internally).
3873 Also fixed some annoying warning messages that the original TRQ
3874 code generated. Also minor changes to TRQ's Makefile.in.
3876 * Added support for querying by Client ID to both WHOIS and
3877 IDENTIFY commands into server, as required by the protocol.
3879 * Removed method function pointers from SilcBuffer structure. They
3880 weren't used to anything and just increased the context size for
3881 no good reason. This change also made silc_buffer_alloc and
3882 silc_buffer_free functions inline functions.
3884 * Disabled command flooding detection support until it's fixed so
3885 that it accepts commands in but does not execute them more than once
3888 * Added silc_net_localhost(), to return local hostname, into
3889 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3890 that must be initialized before calling silc_client_init.
3892 * Added new function: silc_server_send_notify_on_channels to send
3893 notify messages to all channels client has joined. It is assured
3894 that the message is sent only once per client.
3896 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3897 lib/silcutil/silcutil.[ch] as silc_format function. The new
3898 function is generic and is used by server as well, not only by
3899 the logging routines.
3901 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3902 the provided version string was not acceptable. Added new function:
3903 silc_ske_check_version into lib/silcske/silcske.h. The function
3904 must be implemented by the application (client or server) and it
3905 does not reside in the SKE library. The function checks the version
3906 string remote end sent.
3908 * Added back pointers (to opaque context and to SilcSocketConnection)
3909 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3911 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3912 duplicate packet context structure.
3914 * Changed `notify' client operation to send same arguments as client
3915 receives from server except for ID's. ID's are mapped to correct
3916 ID entry and that is returned. Also, if channel entry is not sent
3917 by server but the notify is for channel the channel entry is sent
3918 to application (otherwise application doesn't know that it is for
3919 channel (library gets it from packet's Destination ID)).
3921 * Added silc_client_remove_from_channels into client library to
3922 remove a client from all channels it has joined to. Used when
3923 received SIGNOFF notify from server. Added also new function
3924 silc_client_replace_from_channels to replace old ID entry with
3925 new ID entry on all channels. Used when received NICK_CHANGE
3928 * Fixed ID Cache list handling in silc_idlist_get_client in
3929 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3930 to get (or query) client by ID.
3932 * Updated TODO list.
3934 * Added connection authentication status message defined by the
3935 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3936 support for these into the code in client and server side.
3938 * Added generic function silc_client_send_command to send any command
3939 with variable argument list. Application should use this function
3940 to send commands if the command functions provided by the library
3941 does not suite for the application's user interface needs.
3943 * Added new `failure' client operation. Application is notified about
3944 received failure packet if client is executing a protocol. In this
3945 case the protocol's execution has failed.
3947 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3948 is required by the protocol.
3950 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3951 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3954 * Added status flag to SilcSKE object to indicate realtime status
3955 of the SKE protocol.
3957 * Application receives now exactly same command reply arguments as
3958 the library receives from server. However, if ID is received the
3959 corresponding ID entry is returned to the application (eg. Client
3960 ID is mapped to correct SilcClientEntry entry and that is returned).
3961 Changed command_reply client operation due to this change.
3963 * Changed all ID's in commands and in command replys as ID Payloads.
3964 Change affected both client and server side codes.
3966 All ID's sent in SILC network (with execption of ID's in SILC
3967 Packet header) are sent in ID Payload to support variable length
3970 * Server now notifies nick changes and notifies all clients on
3971 the channels about the new nickname (about the new Client ID,
3974 * Implemented CMODE command to change channel modes. Supports all
3975 channel modes defined by the protocol specs except ban and invite
3976 lists. (Also, private channel key mode is supported but support for
3977 setting private channel key in client is missing, thus, this mode
3978 has no effect on client side (except that server requires that the
3979 client uses private channel key and normal channel traffic does not
3982 Also, invite mode works per se, but INVITE command does not work
3983 yet correctly, so you can set channel as invite only channel but
3984 inviting clients to the channel does not work (it is yet to be
3985 thought what's the best way to do it).
3987 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3988 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3989 Implemented CUMODE command to change user's mode on the channel.
3990 Supports all modes defined by the protocol specs.
3992 * Added NAMES command reply to return users modes on the channel.
3994 * Removed unnecessary and slow ciphers from lib/silccrypt.
3996 * Set SO_KEEPALIVE option to connection sockets by default.
3998 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4000 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4001 redefined the Notify Payload into protocol specs.
4003 * Added silc_id_payload_parse_id to get ID directly from raw
4006 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4009 accept searching by Client ID as well.
4011 * Added support for LEAVE and SIGNOFF notify types in client library.
4013 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4014 to parse ID Payload from raw data.
4016 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Added flags parameter into silc_ske_assemble_security_properties
4019 function in lib/silcske/silcske.[ch].
4021 * Changed notify client operation to fit better for notify messages
4022 sent by server. The notify payload received from server is now
4023 passed to the application (after parsing it to SilcNotifyPayload).
4024 It is application's responsibility to retrieve the arguments
4025 from the payload and show the message the way it wants. The message
4026 sent by server is implementation specific.
4028 * Changed public keys to comply with the protocol specification.
4029 Old public keys are not supported anymore and are not compatible.
4031 * Removed nickname from Channel Payload as the latest draft removed
4032 it. The client must resolve the nickname from the NAMES command
4033 reply received when it joined the channel.
4035 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4037 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Fixed some errors in protocol specification drafts.
4041 * Created lib/silccore/silcnotify.c to implement Notify Payload
4042 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4043 generic payloads described by protocol specifications. The file
4044 includes implementations for ID Payload and Argument Payload.
4046 * Changed Command Payload implementation to use the new Argument
4047 Payload. Changed command_xxxx_payload to command_payload_xxxx
4048 to comply with SILC coding conventions.
4050 * Added suppport for Argument Payload handling in Notify Payload
4051 implementation as protocol requires it. Added the new support
4052 into server and client lib as well.
4054 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Added support for multiple nicknames on same channel. [n] is
4057 added locally to the nickname if there are more than one same
4058 nicknames on the channel.
4060 * Server now sends all nicknames that matched WHOIS request.
4061 Client also shows the list received from server.
4063 * Added TOPIC command to client side. User can now set and show
4064 current topic on channel.
4066 * Added MOTD command to client and server. Also, server sends the
4067 motd when client connects to the server.
4069 * Changed version strings to comply ISO 8601.
4071 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Fixed protocol error handling in client library. It should now
4074 cope even if the SKE fails for some reason.
4076 * Made new protocol specification drafts for submitting to IETF.
4078 * Implemented TOPIC command to server in silcd/command.c.
4080 * Added two new notify types into lib/silccore/silcnotify.h:
4081 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4082 notify nickname change and topic setting/change on a channel.
4084 * API change of command_reply operation in client library. The
4085 application gets now the status type received from server as well.
4087 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4091 * Cras fixed and optimized the packet handling even further and
4092 it should work now. Minor change to the prototype of function
4093 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4095 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Added new function into lib/silcutil/silcschedule.[ch]:
4098 silc_schedule_with_fd to select() a specified fd. The function
4099 returns after timeout expires or data arrives or goes. The
4100 function is used by packet routines to wait that all data is
4101 received from network.
4103 * Fixed data reading from network in lib/silccore/silcpacket.c.
4104 The code now assures that all data is read from the fd and then
4105 continues packet processing. This was a bug fix since the code
4106 used to drop some data in some circumstances.
4108 * Added new function into lib/silcclient/client.[ch]:
4109 silc_client_start_key_exchange to start key exchange after
4110 connection has been established to server. The code internally
4111 now uses this funtion but its main purpose was to provide it
4112 for applications that perform their own connecting. After
4113 application has created a connection it merely calls this
4114 function to start the key exchange between client and server.
4115 The library takes care of everything else after that.
4117 Updated also lib/silcclient/README to explain the usage of
4120 * Do not send to application information that connection has
4121 been established. Application gets notified it by connect
4124 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Applied cras's patch to add silc_schedule_one function. The
4127 function runs scheduler once and returns.
4129 * Fixed the scheduler after cras messed it up. The timeout
4130 handling works now as it's supposed to work.
4132 * Added into lib/silccore/ silcnotify.h to include notify
4133 message types support. Changed silc_server_send_notify*
4134 functions, in server.[ch], to support those new notify types.
4135 Added the support for the notify types into client library,
4136 as well. Added new notify client operation into ops.h in
4139 * Changed silc_server_packet_send_to_channel to send normal
4140 packets instead of just channel message packets. The function
4141 is now used to send the notify packets to channels. It is not
4142 used to send channel message packets anymore, as server never
4145 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4146 va_arg()s as it seems to require it nowadays. I guess, if SILC
4147 is compiled with older va_arg() the new code should work anyway.
4149 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Splitted core library. Core library (lib/silccore) includes
4152 now only SILC protocol specific core (and common) components.
4153 Created new utility library (lib/silcutil) that includes more
4154 generic purpose stuff. The stuff for util library was taken
4155 from the old core library. This was minor and easy split.
4157 * Created SILC Client Library (lib/silcclient) that includes
4158 implementation of the SILC client without user interface. This
4159 was major move from silc/ directory. The code has been changed
4160 so that it is transparent towards the user interface. The
4161 silc/ directory includes now the same user interface as before
4162 and it uses the new client library. Read lib/silcclient/README.
4163 Basicly, the client library performs everything else related
4164 to SILC except user interface handling. Also, configuration
4165 files are considered to be part of user interface and library
4166 does not handle them.
4168 This change also changed a lot of structures, function naming etc.
4169 Most important change was that SilcClientWindow object was
4170 renamed to SilcClientConnection in the client library. Created
4171 also new file lib/silcclient/ops.h. Also added new files
4172 silc/local_command.[ch] and silc/client_ops.[ch].
4174 All these changes were made to make it easier for user interface
4175 designers to create what ever user interface for the SILC client
4178 It is also expected that the server will be moved to lib
4179 directory as well and SILC Server Library will be created;
4180 sometimes in the future.
4182 * Removed Local commands from lib/silccore/silccommand.h as
4183 they are application specific and new client library does not
4184 handle any of those anymore.
4186 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4187 old client implementation in silc/.
4189 * Added support for callback functions in SILC_LOG_* macros.
4190 Application can now set its own callbacks that will be called
4191 instead of using the default functions that will always print
4192 the debug messages to stderr (or stdout). Also, debugging can
4193 now be disabled by setting silc_debug to FALSE and re-enabled by
4194 setting it to TRUE. Note, that logging will still work even
4195 if debugging is disabled.
4197 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4198 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4199 silc_log_reset_debug_callbacks.
4201 * To enable debugging in silc client one must give now -d
4202 option on command line.
4204 * Changed silc_schedule_init to automatically allocate task queues
4205 if they are not allocated before calling it.
4207 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Added GMP 3.1 into math library.
4211 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4214 a channel in SILC network. The packet is used by servers and
4215 routers to notify other routers that user has left a channel.
4216 This little feature was missing until now. Added the feature
4217 to protocol specification as well.
4219 Added functions: silc_server_send_remove_channel_user and
4220 silc_server_remove_channel_user into server.[ch].
4222 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4223 lib/silccore/silcpacket.h. However, they are not implemented
4226 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Fixed joining to a channel and sending channel messages
4229 between server and router. The channel message sending should
4230 now work inside a cell.
4232 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Fixed the private message sending between server and router.
4235 The private message sending should now work inside a cell.
4237 * Added silc_server_replace_id into server.[ch] to replace
4238 existing ID in the SILC network.
4240 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4241 and silc_idlist_replace_server_id into idlist.[ch] in server.
4243 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Fixed the server to server connections. Server can again now
4246 connect to router. Router to router connections probably does
4249 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added dynamic protocol registering support. Now protocols can
4252 registered and unregistered on the fly. Patch by cras.
4254 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added lib/contrib directory to hold routines that some platforms
4257 don't have but are needed by SILC.
4259 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4260 into lin/contrib to provide getopt() and getopt_long() for
4261 those who don't have it.
4263 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added AWAY command to client. When away message is set and
4266 client receives a private message packet the client automatically
4267 replies to the sender with the away message.
4269 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4270 bug seemed to be the cause of recent problems when compiling
4273 * Added version detection support to SKE protocol specification
4274 and added the new changes to the SKE implementation as well.
4275 There were other minor changes in the SKE protocol as well.
4277 Many changes in lib/silcske/silcske.[ch] and in
4278 lib/silcske/payload.[ch].
4280 * Added ^U functionality, clear input line. Patch from cras.
4282 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Mainly small bugfixes on core library. Fixed some debugging
4285 logging and buffer overflow in silclog.c.
4287 * Updated config.sub and config.guess on the distribution tree.
4289 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Added command lagging support in server. Client may execute
4292 commands now only once in two seconds.
4294 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Optimized packet reception. MAC computation and checking is now
4297 also more optimized. A lot previously duplicated code is now
4298 used as generic by both client and server.
4300 * Fixed key pair generation in clientutil.c
4302 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Added into lib/silccore/silcbufutil.[ch] new function;
4305 silc_buffer_realloc.
4307 * Moved generic packet sending/encryption functions to
4308 lib/silccore/silcpacket.[ch] from client and server. Some
4309 rewriting of the functions.
4311 * Moved all generic packet reception/decryption functions to
4312 lib/silccore/silcpacket.[ch] from client and server. The
4313 packet processing is now much cleaner in both client and server.
4314 These were major changes in both client and server.
4316 * Created many common functions in server to do packet sending.
4317 Previously code were duplicated a lot, this has been removed
4320 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Rewrote major parts of the ID cache system. Don't know
4323 whether it is better now or not but at least the API is more
4326 * Major rewrite on ID cache stuff on client because of the ID
4327 cache API changes. Added idlist.c to client.
4329 * Also major rewrite on ID cache stuff on server as well.
4330 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4331 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4332 in hand, instead they are all put into the ID cache system now.
4333 All server_idlist_* routines uses ID cache now instead of
4334 traversing its own lists (those lists does not exist anymore).
4335 SilcIDList though still exists. Also, SilcXXXEntry's are
4338 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Finally made the SKE implementation compliant to the protocol
4341 specification. All mp integers are now binary encoded as
4342 opposed being HEX encoded.
4344 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4347 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4348 functions: silc_[encode/decode]_pem. Also added function
4349 silc_encode_pem_file to PEM encode with newlines ('\n') for
4352 * SILC public keys are now encoded either PEM or binary. Same
4353 option is for private keys as well. By default private keys
4354 are binary encoded and public keys PEM encoded. Silly HEX
4355 encoding were removed.
4357 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4358 function to create fingerprints.
4360 * Fixed a bug in SHA1; does not change the original data anymore.
4362 * Partly implemented INFO command on client and server side.
4363 Fixed CLEAR command. Changes to SERVER command; show current
4364 server(s) when giving command without arguments. Added
4365 VERSION command to client.
4367 * Added check to server that unregistered connections cannot
4368 execute commands (unless it is specificly allowed).
4370 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Fixed screen refresh.
4374 * Fixed channel joining bug from client. On some circumstances
4375 client tried to join to a channel it had already joined.
4377 * Added public key verification process into client's protocol.c.
4378 The client now verifies the public key from user and saves
4379 it into ~./silc/serverkeys/ directory.
4381 Added into: clientutil.[ch]: silc_client_verify_server_key.
4383 * Changed SKE protocol's silc_ske_initiator_finish function
4384 to accept callback function that verifies the received public
4385 key. Removed old silc_ske_verify_public_key function.
4387 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4390 silc_pkcs_private_key[_data]_set.
4392 * Made the password and public authentication more cleaner in
4393 server's protocol.c.
4395 * Removed historic and obsolete protocol `channel_auth' from
4396 both client and server.
4398 * Removed wrong way of sending command status messages from
4399 server to client in server's command.c. The old way violated
4400 protocol specification.
4402 Changes to silccore/silccommand.[ch]: removed
4403 silc_command_encode_status_payload -> not needed anymore,
4404 changed silc_command_encode_payload_va to accept extra
4405 argument on variable argument list. The argument type must
4406 now be provided to the function. Also, added new function:
4407 silc_command_encode_reply_payload_va which is same as
4408 normal command_encode_payload_va except command status type
4409 is provided as extra argument.
4411 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Added ~./silc directory handling. The directory includes the
4414 public and private keys for the client.
4416 Added silc_client_check_silc_dir, silc_client_create_identifier
4417 and silc_client_load_keys.
4419 * Implemented SILC protocol compliant public key. Added public
4420 and private key saving to and loading from files.
4422 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4423 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4424 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4425 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4426 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4428 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4429 silc_pkcs_load_[public/private]_key.
4431 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Added silc_server_get_route (route.[ch]) to get connection
4434 data for the fastest route for given ID.
4436 * Implemented INVITE command on client and server. The command
4437 were re-defined in the SILC Protocol Specification and the
4438 implementation now complies with the specification.
4440 * Implemented PING command on client and server.
4442 * Implemented NAMES command on client and server. The server side
4443 supports currently only normal server not router server yet.

4451 again. This change was made to the protocol as well. Server
4452 should not violate the protocol specification anymore.

4456 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4457 was tested. SOCKS4 was not but should work anyway.
