1 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * The server now performs the incoming host IP/DNS lookup
4 using the silc_socket_host_lookup and thus does not block
5 the server anymore. Affected file silcd/server.c.
7 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Added new function silc_schedule_wakeup that is used in
10 multi-threaded environment to wakeup the main thread's
11 schduler. It needs to be used when a thread adds a new task
12 or removes a task from task queues. After waking up, the
13 scheduler will detect the task queue changes. If threads
14 support is not compiled in this function has no effect.
15 Implemented the wakeup mechanism to both Unix and WIN32
16 systems. Affected files are lib/silcutil/silcschedule.[ch],
17 lib/silcutil/unix/silcunixschedule.c and the
18 lib/silcutil/win32/silcwin32schedule.c.
20 * Added new function silc_task_queue_wakeup to wakeup the
21 scheduler by the specified task queue. Affected file
22 lib/silcutil/silctask.[ch].
24 * The silc_socket_host_lookup_start now wakes up the scheduler
25 after adding the timeout task. Affected file is
26 lib/silcutil/silcsockconn.c.
28 * The silc_socket_host_lookup is synchronous now if the threads
29 support is not compiled in. However, the callback is still
30 called asyncronously through the scheduler, anyway. Affected
31 file lib/silcutil/silcsockconn.c.
33 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
35 * Added new function silc_socket_host_lookup to perform
36 asynchronous IP and FQDN lookups for the socket connection.
37 Affected files lib/silcutil/silcsockconn.[ch].
39 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
41 * Added SILC_MUTEX_DEFINE to define the mutex on environments
42 that may or may not compile the mutex support in.
44 Changed the silc_mutex_alloc interface. It allocates the
45 mutex now to the sent pointer and returns TRUE or FALSE.
47 Affected file lib/silcutil/silcmutex.h.
49 * Wrote the SILC Task Queue interface to support multi-threads.
50 Affected file lib/silcutil/silctask.[ch].
52 * Wrote the SILC Scheduler to support multi-threads. Affected
53 file lib/silcutil/silcschedule.c.
55 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
57 * Implemented the SILC Mutex API and SILC Thread API for WIN32
58 in lib/silcutil/win32/.
60 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
62 * Defined SILC Mutex API and SILC Thread API and implemented
63 them for Unix. Affected files are
64 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
65 lib/silcutil/unix/silcunixmutex.c and
66 lib/silcutil/unix/silcunixthread.c.
68 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
70 * Fixed the silc_server_remove_clients_by_server's channel
71 key re-generation. The hash table handling was incorrect
72 and would not work with many channels. Affected file is
75 * Fixed some memory leaks around the server code.
77 * Rewrote the silc_server_get_users_on_channel to support IPv6
78 based Client ID's. Affected file silcd/server.c.
80 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
81 specification. However, a separate document must be written
82 to define the detailed signing procedure and the payload
83 associated with the flag. Defined the flag to the
84 lib/silccore/silcchannel.h as well.
86 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
88 * Changed the dynamic tables to static size tables in the
89 lib/silccrypt/silchmac.c.
91 * Removed GCC dependencies from the code. A patch by cras.
93 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
95 * Do not show the error "Error receiving packet bla bla"
96 in server if it really was not an error (-2 means that reading
97 is pending). Affected file silcd/server.c.
99 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
101 * Fixed a possible crash in silc_server_remove_clients_by_server
102 in silcd/server.c. Fixed there also some memory leaks.
104 * Fixed the silc_idlist_replace_client_id. It could replace
105 wrong key in the hash table. Affected file silcd/idlist.c.
107 * Do not check whether there are global users on the channel
108 if the channel->global_users is FALSE. Affected functions
109 silc_server_remove_from_one_channel and
110 silc_server_remove_from_channels in silcd/server.c. Also,
111 do not check if the removed client is local as we can be
112 sure that global client was not removed from the channel
113 and checking for global users is not needed.
115 * The silc_server_remove_clients_by_server now re-generates
116 the channel keys correctly for those channels that had
117 clients removed from them. Affected file silcd/server.c.
119 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
121 * Found the reason of random crashes in the server. We weren't
122 ignoring the SIGPIPE signal (which can be sent in write())
123 and it crashed the server. Affected file silcd/silcd.c.
125 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
127 * Assure that sock->user_data is not NULL in the function
128 silc_server_packet_send in silcd/packet_send.c.
130 * Disconnect the remote connection if it could not be added
131 to any ID lists in the server. The affected file is
134 * Check in silc_server_packet_send[_real/dest] that the
135 socket is not disconnecting and ignore the data if it is.
136 Affected file silcd/packet_send.c.
138 * Define inline to __inline on native WIN32 compilation.
139 Affected file includes/silcwin32.h.
141 * Added some explicit type casts for inline code since MSVC
142 require them. Affected files lib/silcutil/silcbuffer.h,
143 lib/trq/silcdlist.h and lib/trq/silclist.h.
145 * Print warning in log files from now on if the packet
146 decryption fails. Affected file silcd/server.c.
148 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
150 * Changed the `say' client operation's interface to accept
151 new `type' argument to indicate the type of the message sent
152 by the library. The application may filter the library's
153 messages according the type. The affected file is the
154 lib/silcclient/silcapi.h.
156 * Added two new functions to lib/silcclient/silcapi.h:
157 silc_client_del_client and silc_client_del_client_by_id.
158 Affected file lib/silcclient/idlist.c.
160 * Moved the clientincludes.h from includes/ to silc/ and
161 serverincludes.h from includes/ to silcd/.
163 * The modes for the CMODE and CUMODE are now passed as
164 uint32 for application with COMMAND_REPLY. The affected
165 file is lib/silcclient/command_reply.c.
167 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
169 * /WHOIS without arguments shows client's own information.
170 Affected file lib/silcclient/command.c.
172 * Changed PING to not accept any arguments. The specs
173 says that client can ping only the connected server so
174 requiring an argument is not needed. Affected file is
175 lib/silcclient/command.c.
177 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Fixed a fatal bug in private message sending and reception
180 encryption and decryption when using private message keys.
181 The implementation was incorrect and did not follow the
182 specification. It causd that some of the message were
183 lost since it did not use the sending and receiving keys
184 as the protocol suggests. This has been fixed and will cause
185 incompatibilities with older clients when sending private
186 message encrypted with private message keys. Affected files
187 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
188 and various other in Irssi SILC Client.
190 Added `responder' boolean argument to the functions
191 silc_client_add_private_message_key[_ske] to indicate when
192 the key is added as responder or initiator of the key
195 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
197 * Removed the silc_ske_check_version function and created
198 a SilcSKECheckVersion callback. Added also a function
199 silc_ske_set_callbacks that is now used to set all SKE
200 callbacks. The callback functions are not given to
201 the SKE functions anymore, but this function is used to
204 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
206 * Added `silc_version' argument to the silc_client_alloc
207 to define the version of the application for the library.
208 The library will use the version string to compare it
209 against the remote host's (usually a server) version
210 string. Affected file lib/silcclient/silcapi.h
212 * Added the KE protocol context to Key Agreement context
213 in client library so that we can abort the SKE if it
214 is in process when we get timeout. Affected file is
215 lib/silcclient/client_keyagr.c.
217 * Do not resolve the client ID forever if it returns in the
218 first time that such client does not exist. This was done
219 for example with private message. Affected file is
220 lib/silcclient/client_prvmsg.c.
222 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
224 * Do not add regex.h for WIN32. The affected file
225 includes/silcincludes.h.
227 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
228 not work yet 100%. It generates the DLL's automatically
229 when compiling with --with-win32 under cygwin.
231 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
233 * lib/contrib/regex.c is not compiled on WIN32.
235 * Added silc_net_get_socket_opt function to the
236 lib/silcutil/silcnet.h.
238 * Added includes/silcwin32.h for WIN32 specific includes
241 * Do not use ptime structure or any of the posix process
242 functions on WIN32 in lib/silccrypt/silrng.c.
244 * Added silc_gettimeofday to provide generic function
245 for struct timeval on all platforms. Added the function
246 to lib/silcutil/silcutil.h.
248 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
250 * Moved the lib/silccore/silcsockconn.[ch] to the utility
251 library as they clearly belong there. As a plus side we
252 can make the actual socket connection routines platform
255 Added also new generic function silc_socket_read and
256 silc_socket_write (that used to be silc_packet_[read/write].
257 The implementation of these are platform specific.
259 * Added WIN32 specific routines of silc_socket_[read/write]
260 to lib/silcutil/win32/silcwin32sockconn.c.
262 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
264 * Added preliminary support for native WIN32 compilation under
265 cygwin (using the -mno-cygwin option for GCC) to the
266 ./configure.in.pre. The --with-win32 now prepares the
267 compilation for native WIN32.
269 * Rewrote the SILC Scheduler interface in the file
270 lib/silcutil/silcschedule.h. The scheduler is now context
271 based and does not have anymore any global static scheduler.
272 Moved the Unix scheduler to the lib/silcutil/unix/ directory
273 and created lib/silcutil/win32 directory for WIN32 based
276 * Added Unix specific network routines to the
277 lib/silcutil/unix/silcunixnet.c and the old
278 lib/silcutil/silcnet.c includes now only generic routines.
280 Added WIN32 specific network routines to the
281 lib/silcutil/win32/silcwin32net.c.
283 * Added Unix specific utility functions from the
284 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
286 * Added WIN32 SILC Scheduler to the file
287 lib/silcutil/win32/silcwin32schedule.c. The code is of course
290 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
292 * Do not handle JOIN notify in the server if the target client
293 is not registered (idata->registered == FALSE). The affected
294 file is silcd/packet_receive.c.
296 * Update the nickrec->founder in event_cumode in the Irssi SILC
297 client. Affected file irssi/src/silc/core/silc-channels.c.
299 * Fixed the CUMODE_CHANGE notify handling in the server when
300 server and router are announcing their clients on channels.
301 Now the mode changes are saved and notified correctly. The
302 affected file is /silcd/packet_receive.c.
304 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
305 They really did not replace the cache entry in the ID Cache.
306 Now they do that. Affected file silcd/idlist.c.
308 * Fixed the KICK notify handling in the Irssi SILC client to
309 update the channel records so that the kicked client does not
310 appear to be on the channel. The affected file is
311 irssi/src/silc/core/silc-channels.c.
313 * Always update the conn->current_channel when executing command
314 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
316 * Fixed the KILL notify handling in Irssi SILC client to remove
317 the killed client on all channels.
319 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * Fixed the silc_parse_command_line to remove extra spaces
322 from the start and end of the arguments. Affected file is
323 lib/silcutil/silcutil.c.
325 * Cancel and free any active protocol in the function
326 silc_server_close_connection. Affected file silcd/server.c.
328 * Cancel and free any active protocol in the function
329 silc_client_close_connction. Affected file is
330 lib/silcclient/client.c.
332 * Do not execute the KILL command for clients that are in
333 history (ie. they are not in the network). Affected file is
336 * Fixed KILL notify handling, client does not crash anymore.
337 Affected file irssi/src/silc/core/silc-channels.c.
339 * Reduced the default packet buffer size from 2048 to 1024 in
340 lib/silccore/silcpacket.c.
342 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
343 counter to the SKE context that is incresed when the SKE library
344 performs async operation outside the library. If the outside
345 process frees the SKE context and FREED status will be set
346 and the library will detect after the sync operation that the
347 libary is freed. The affected files are
348 lib/silcske/silcske[_status].[ch].
350 * Resolve the client entry information in the function
351 silc_client_channel_message to assure that NULL pointer is not
352 passed as client entry to the application. */
354 * Fixed the task timeout calculation to assure that there is
355 never negative timeouts. The affected file is
356 lib/silcutil/silcschedule.c.
358 * Fixed the channel user mode notification sending in server.
359 It was sent point-to-point to the router (or to server by router)
360 but it needs to be destined to a channel. The routines now
361 supports sending the channel user mode notifys to the channels
362 when announcing clients and channels. Affected files are
363 silcd/server.c and silcd/packet_receive.c.
365 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
366 It did not actually replace the old channel entry in the cache.
367 Affected file lib/silcclient/client_notify.c.
369 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Fixed a possible crash in silc_packet_send_prepare. It now
372 assures always that there is enough space in the buffer and
373 at the tail area of the buffer (for MAC).
375 Fixed the inbound buffer reallocation in silc_packet_read.
376 It was old code and did not handle the reallocation correctly.
379 The affected file is lib/silccore/silcpacket.c.
381 * Fixed buffer overflow in silc_parse_nickname in the file
382 lib/silcutil/silcutil.c.
384 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
386 * make install generates new server keys only if there is not
389 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
391 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
392 Added check that if the NOREPLY is set then we will not send
393 the away message. This avoids infinite loop of away messages
394 if both clients are away. The affected file is
395 lib/silcclient/client_prvmsg.c.
397 * Fixed client crash if /NICK was given without arguments.
398 Affected file lib/silcclient/command.c.
400 * Server does not send the invite list in INVITE command back
401 to the client if the list was not altered. Added this notion
402 to the protocol spec as well. Affected file silcd/command.c.
404 Fixed possible crash in INVITE command by checking the
405 value of silc_server_get_client_route command.
407 * Fixed the INVITE notify type handling. The arguments are now
408 taken in correct order and client does not crash. The affected
409 file is irssi/src/silc/core/silc-channels.c.
411 Removed the "Inviting xxx to channel" message from the
412 client library away and let the application handle it.
413 Affected file lib/silcclient/command.c. Added that message
414 to Irssi SILC client's message formats.
416 * Fixed CMODE command crash in client. It now checks the
417 amount of arguments correctly and does not crash. The affected
418 file is lib/silcclient/command.c.
420 * Do not create new channel automatically in silc_channels_join
421 but check whether the channel by that name already exists.
422 Affected file irssi/silc/core/silc-channels.c.
424 * Do not send the SERVER_SIGNOFF to router if the disconnected
425 entity was the router. Affected file silcd/server.c.
427 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
428 SILC client as it was missing from there.
430 Added the handling of the KICK notify to the Irssi SILC client
431 as it was missing. Added "you have been kicked" message to
432 Irssi SILC client's message modules formats.
434 Added the handing of the KILL notify to the Irssi SILC client
435 as it was missing. Added the kill message module formats
438 The affected file is irssi/src/silc/core/silc-channels.c.
440 * The router did not save the channel mode the server announced.
441 Affected file silcd/packet_receive.c.
443 * Fixed a possible crash in INFO command in server. If the
444 server did not provide the server info it crashed. Affected
445 file silcd/command.c.
447 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
449 * Fixed the GETKEY command in the server to check also the
450 global list. Otherwise the GETKEY would not work correctly
451 in normal SILC server. Affected file silcd/command.c.
453 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
455 * Fixed GETKEY crash, it crashed if the command did not succseed.
457 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
460 is now real and not just an macro interface to GMP.
462 Removed the entire GMP from the source tree and imported new
463 NSS MPI library instead. Reason for removing GMP is that it is
464 extremely large and compiles extremely slow. The NSS MPI
465 is only a few files and compiles in less than 10 seconds.
466 The speed is also about the same as GMP. The MPI is imported
469 If the system has GMP installed we will still use the GMP.
470 If it is not then the NSS MPI will be compiled.
472 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
474 * Merged a long nickname (127 characters long) crash bugfix from
475 Irssi CVS tree. Affected file irssi/src/core/misc.c.
477 * Merged a freed memory reference bugfix from Irssi CVS tree.
478 Affected file irssi/src/core/commands.c.
480 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
482 * Added the server's public key sving and verification to the
483 server when performing the SKE. This was missing and the
484 remote server's (or router's) public key was accepted without
485 checking whether we have it previously or trust it at all.
486 Affected file silcd/protocol.c.
488 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
490 * Check in the silc_server_timeout_remote if protocol is active
491 and make sure that the protocol's final callback is called so
492 that all memory if freed. Affected file silcd/server.c.
494 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * silc_server_whois_send_reply crashed the server if the nickname
497 was 127 characters long. Affected file silcd/command.c.
499 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
501 * Added sanity check to the silc_server_new_client. If the hostname
502 is provided inside username then check that the provided hostname
503 really is the same as the resolved one. If the hostname was not
504 resolved then check it from the public key. Affected file is
505 silcd/packet_receive.c.
507 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
508 if the server disconnected us and the connection is not valid
509 anymore. Affected file irssi/src/silc/core/silc-channels.c.
511 * Moved the silc_client_[chmode|chumode|chumode_char] away from
512 the library to the lib/silcutil/silcutil.[ch].
514 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
516 * Close log file after open. Affected file
517 lib/silcutil/silclog.c.
519 * Check whether sock == NULL in silc_client_send_packet and return
520 if it is. Affected file lib/silcclient/silcclient.c.
522 * Check rec->entry == NULL in the Irssi SILC Client before
523 sending the channel message. Affecte file is
524 irssi/src/silc/core/silc-servers.c.
526 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * Merged a splitted window bugfix from Irssi CVS tree. The
529 affected file is irssi/src/fe-text/textbuffer-view.c.
531 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
532 It did not print nickname.
534 * Improved the distributions system a bit.
536 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
539 irssi/src/fe-text/gui-window.c.
541 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
542 to in-active server. The affected file is
543 irssi/src/silc/core/client_ops.c.
545 * Resolve the client in USERS command reply if the entry does
546 not have username resolved. The affected file is
547 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
548 command to WHOIS command to really resolve stuff. The USERS
549 is not used any more in any critical section so WHOIS can
550 be used even though it might be slower than IDENTIFY.
552 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
555 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
557 * Changed the protocol API a bit more consistent in the
558 lib/silccore/silcprotocol.[ch].
560 * Changed the following headers to ROBODoc format:
562 lib/silccore/silcpayload.h
563 lib/silccore/silcprotocol.h
564 lib/silccore/silcsockconn.h
566 All core library headers are now formatted.
568 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Fixed a bug in Irssi SILC client; do not show that you are
571 server/router operator if you really are not. Affected file is
572 irssi/src/silc/core/client_ops.c.
574 * Renamed silc_command_free_payload to silc_command_payload_free.
575 Affected file lib/silccore/silccommand.h
577 * Added silcmath.h to include the prototoypes of various routines
578 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
581 * Changed the following headers to ROBODoc format:
583 lib/silccore/silcchannel.h
584 lib/silccore/silccommand.h
585 lib/silccore/silcid.h
586 lib/silccore/silcidcache.h
587 lib/silccore/silcmode.h
588 lib/silccore/silcnotify.h
589 lib/silccore/silcpacket.h
590 lib/silcmath/silcmath.h
592 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * Added checking to the server code not to start the server if
595 ciphers and stuff are not configured properly. Affected files
596 silcd/serverconfig.[h] and silcd/server.c.
598 * Changed the layout of the header files of the public interfaces
599 in the SILC libraries. The new layout supports ROBODoc
600 documentation tool (and some others) so that it is easy to create
601 a library reference manual. All the other headers and source
602 code must still follow the CodingStyle document. Also source
603 code must not include these ROBODoc stuffs, only the headers.
604 Furthermore, all public interface headers must now be named
605 by using `silc' prefix, example: silcapi.h, silccipher.h.
606 Some files were renamed due to this. All the other headers
607 must not be used as public interfaces. I will update the
608 CodingStyle document later. Changed following headers, so far:
610 lib/silcclient/silcapi.h
611 lib/silccore/silcauth.h
612 lib/silccore/silcprivate.h
613 lib/silccrypt/silcdh.h
615 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Removed silc_client_packet_send_flush from the client library
620 as it is not needed. Affected file lib/silcclient/client.[ch].
622 * Added printing of message of unresolved authentication method
623 to the Irssi SILC client. Added it to the module formats.
624 Removed the same message from the client library.
626 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Added new distribution feature, DISTLABEL. Every distribution
629 can define own preprocessor label that can be used in the
630 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
631 file distributions, acconfig.h.pre and prepare.
633 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
635 * Added Makefile.defines_int to include the actual definitions
636 for Makefile.defines.in. Tested the new distribution system,
637 created distributions and tested installation.
639 * Added AWAY message printing to the Irssi SILC client. Added
640 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
642 * Added SCONNECT command to call the SILC's CONNECT command.
643 Cannot use CONNECT directly since Irssi uses that internally.
644 Affected file irssi/src/silc/core/silc-servers.c.
646 Added ACTION local command. It is same as ME command but takes
647 the channel as mandatory argument.
649 Rewrote some of the Irssi's help files to suite for SILC
652 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Added Makefile.defines[.in] that should for now on be included
655 in all Makefile.am file in the source tree. That file includes
656 all common compilation definitions for SILC source tree.
658 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
660 * Minor changes to the ./prepare script to change the package
661 name according the distribution name to the configure.in.
663 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Created new distribution system. Added file `distributions'
666 that defines all the distributions that can be created out of
667 the SILC source tree. The ./prepare script now reads that
668 file to determine how to prepare the distributions. The
669 first argument to the ./prepare is the name of the distribution
670 and second is the version of the distribution. If given
671 without arguments it creates the default (toolkit) distribution
672 with the default version (defined in ./prepare).
674 All Makefile.am files that are subject to the distributions
675 are now named as Makefile.am.pre. These are ./Makefile.am
676 and lib/Makefile.am. Others may be changed later.
678 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
680 * Added invite list, ban list, some key management and connection
681 error message printing to module formats in the Irssi SILC client.
683 * Added new silc_client_set_away_message to set the away message
684 that is back to the person who sent private message. The
685 affected file lib/silcclient/silcapi.h and the
686 lib/silcclient/client_prvmsg.c.
688 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
690 * Fixed the private message sending in the Irssi SILC client,
691 added local command KEY to the Irssi SILC client.
693 Added key management and key agreement message formats to the
694 irssi/src/fe-common/silc/module-formats.[ch].
696 Added USERS (alias WHO) printing, server/router operator
697 indication and LIST command printing to the module formats.
699 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Fixed channel joining notify handling, cumode notify handling
702 from Irssi SILC client.
704 * Added SILC specific module-formats to the Irssi SILC client so
705 that SILC specific message hilighting, colors etc is possible.
706 Affected file irssi/src/fe-common/silc/module-formats.[ch].
708 Added channel mode, channel user mode, actions, notices,
709 whois and whowas printing to the the module-formats.c.
711 * Fixed a bug in channel deletion in the server. The channel
712 is not left to the cache even if the channel founder auth mode
713 is set when there are no users anymore on the channel. Affected
716 * The silc_net_localhost now resolves the entire hostname including
717 the domain name. Affected file lib/silcutil/silcnet.c.
719 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * Changed the ask_passphrase client operation to be ascynchronous.
722 It has now a completion callback and a context that the
723 application must call after it has got the passphrase from
724 the user. Affected files lib/silcclient/silcapi.h,
725 lib/silcclient/protocol.c, lib/silcclient/command.c and
728 Added SilcAskPassphrase callback that the application calls
729 to deliver the passphrase to the library.
731 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
732 The public key verification and especially a certificate
733 verification is asynchronous procedure.
735 Added new SILC_SKE_STATUS_PENDING status to indicate the
736 request is pending and a callback will be called to finalize
739 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
740 indicate that remote end did not send its public key (or
741 certificate), even though we require it. Added check for this
742 condition in the SKE. This was a security bug, now fixed.
744 Defined new SilcSKEVerifyCbCompletion callback that is called
745 when the verification process is completed.
747 The affected files lib/silcske/silcske_status.h and
748 lib/silcske/silcske.[ch].
750 * Changed the verify_public_key client operation to be async
751 as well. Defined SilcVerifyPublicKey callback that is used to
752 indicate the success of the public key verification process.
754 Changed the server and client to use the new async client
757 * Changed the Irssi SILC client's internal scheduler to be called
758 twice as many times as it used to be. As a result the client
759 should be a bit faster now. Affected file is
760 irssi/src/silc/core/silc-core.c.
762 * Added support to Irssi SILC client of asynchronous public key
763 verification and passphrase inquiry. Affected file is
764 irssi/src/silc/core/silc-core.c.
766 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
768 * Do not say "You have left channel %s" in client library.
769 Moved it to the application. Affected files are
770 lib/silcclient/command.c and silc/client_ops.c.
772 * Fixed silc_client_get_clients. Command context was not
773 duplicated and was freed memory in the callback. Affected
774 file lib/silcclient/idlist.c.
776 * Do not say "you are now talking..." on JOIN command in the
777 client library. The appliation must handle it.
779 * Do not say ".. changed topic to" in command reply in the
780 client libary. The application must handle it.
782 * Fixed TOPIC command sending in the client library.
784 * Fixed a memory leak in silc_client_command_free in the file
785 lib/silcclient/command.c.
787 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Imported a modified version of Irssi client to the source tree.
790 The Irssi will be used to create a new client called
791 Irssi SILC. Imported to irssi/.
793 Added silc_core_init_finish function to the Irssi. Affected
794 file irssi/configure.in.
796 A lot changes in the Makefile.ams around the irssi tree.
798 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Do not rehash if the new size is same as the old size of the
801 hash table, in the silc_hash_table_rehash*. The affected file
802 lib/silcutil/silchashtable.c.
804 * Replaced hash_table_del_by_context calls from the server
805 (when channel->user_list and client->channels) to the
806 hash_table_del as it is sufficient and faster.
808 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
810 * Added silc_hash_table_list, silc_hash_table_get and the
811 SilcHashTableList structure to provide an alternative way to
812 traverse the hash table. The affected files are
813 lib/silcutil/silchashtable.[ch].
815 * Changed the server's idlist routines to use the hash table
816 routines to optimize the code.
818 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Replaced the client entry's `channel' list and channel entry's
821 `user_list' list to hash tables for optimized lookup. Changed
822 the code to use the hash table interface around the code.
823 Affected file lib/silcd/idlist.[ch].
825 * Added `auto_rehash' boolean argument to the function
826 silc_hash_table_alloc to indicate whether the hash table should
827 auto-rehash when it thinks is appropriate time. It will
828 increase the hash table size if the there is twice as much
829 entries in the table than the size of the table, and will
830 decrease the size if there are twice as less entries than
831 the size of the table.
833 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
835 * Fixed silc_xxx_get_supported to not crash at some circumstances.
837 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
839 * silc_idcache_purge_by_context deletes the entry now by context
840 as it is supposed to do. Affected file lib/silccore/idcache.c.
842 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
843 client is not anymore valid (WHOWAS givens the info) and not
844 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
846 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * Removed the `data' and `data_len' arguments from the ID Cache
849 interfaces and added `name' argument. ID Cache does not handle
850 anymore the binary data only a names associated with given ID.
852 * When hashing a Client ID with silc_hash_id the entire ID is
853 not hashed anymore, instead only the hash of the Client ID is
854 hashed. This way we can access the Client ID from the cache
855 with Client ID but with the hash of the ID (which is a hash of
856 the nickname) as well without any difference in performance.
858 Added also silc_idcache_find_by_id_one_ext to do one on one
859 searching when we have the actual ID. Added also function
860 silc_hash_client_id_compare. The affected files are
861 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
863 * When hashing the name associated with a ID it is always done
864 in lowercase. This way we can access the cache without worrying
865 about case-sensitivity, even though, for example nicknames are
868 * Fixed a bug in server with channel message sending. It put
869 wrong ID type as destination ID. The affected file
872 * silc_idcache_del_by_context now deletes from all hash tables
873 by context. Affected file lib/silccore/idcache.c.
875 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Changed the client library to use the new ID Cache interface.
878 Changes around the source tree.
880 * Added silc_hash_table_rehash_ext to rehash with specific
881 hash function. Affected file lib/silcutil/silchashtable.[ch].
883 * Added silc_hash_string_compare to compare two strings in the
884 hash table. Affected file lib/silcutil/silcutil.[ch].
886 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
888 * Added new function silc_idcache_del_by_context into the
889 lib/silccore/idcache.[ch].
891 * Changed the server's ID list routines to use the new ID Cache
892 interface. Changes around the source tree.
894 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Added silc_hash_table_del[_by_context]_ext functions in to the
897 lib/silcutil/silchashtable.[ch].
899 Removed silc_hash_table_find_all* routines and added new
900 silc_hash_table_find_foreach to replace them.
902 Added silc_hash_table_replace_ext function as extended
903 replacing function. Separated the simple hash table interface
904 from the extended hash table interface in the file
905 lib/silcutil/silchashtable.h.
907 * Fixed minor bugs and changed it to use some of the new
908 hash table functions in lib/silccore/idcache.c
910 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Added new function silc_hash_table_find_all to return all keys
913 in the hash table by the specified key. As the hash table is
914 collision resistant it also makes it possible to have several
915 duplicate keys in the hash table. This function may be used to
916 find all of the keys from the hash.
918 Added user_context arguments to the SilcHashFunction,
919 SilcHashCompare and SilcHashDestructor to deliver user specified
922 Added new fuctions silc_hash_table_find[_all]_ext to do
923 extended lookup with specified hash and compare functions and
924 specified user contexts.
926 Added new function silc_hash_table_add_ext to add the key
927 with specified hash function and user context.
929 Added new function silc_hash_table_foreach to traverse all
930 entrys in the hash table. Added SilcHashForeach callback
933 Added new function silc_hash_table_del_by_context to delete
934 the entry only if the context associated with the key matches.
936 Affected files are lib/silcutil/silchashtable.[ch].
938 * Removed silc_hash_[server/client/channel]_id and added just
939 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
940 silc_hash_id_compare to compare two ID's using as the hash table
941 comparison function. Added also silc_hash_data to hash
942 binary data and silc_hash_data_compare to compare it.
944 * Removed silc_idlist_find_client_by_hash as it is not needed
945 anymore. Affected file silcd/idlist.[ch].
947 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
948 to use internally the SilcHashTable. The new ID Cache is a lot
949 faster than the old one. Some of the ID Cache interface was also
950 rewritten and obsolete and stupid functions were removed.
952 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
954 * Added entry_count field to the SilcHashTable to keep the number
955 of the entries in the table. Implemented the function
956 silc_hash_table_rehash. Added new function
957 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
959 Fixed a minor bug in silc_hash_table_free.
961 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
962 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
963 into the lib/silcutil/silcutil.[ch].
965 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * Implemented a collision resistant hash table into the
968 lib/silcutil/silchashtable[ch]. See the header and the source
969 for the SilcHashTable API.
971 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Merged dotconf version 1.0.2 into lib/dotconf.
975 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * Do not compile anything in lib/silcsim/* if the SIM support
978 is not enabled. The tree should now compile without problems
981 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Compiled the SILC under cygwin. Compiled and tested briefly
984 without problems. More tests needed. The SIMs didn't compile
987 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
989 * Fixed possible crash in silc_get_username in the
990 lib/silcutil/silcutil.c.
992 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Fixed a va_arg in silc/client_ops.c.
996 * Oops, RC5 routines were named AES and caused some problems
997 when not using SIM's. Affected file lib/silccrypt/rc5.c.
999 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1001 * Added new SilcIDIP structure into the lib/silccore/id.h and
1002 replaced the old `ip' fields from all SILC ID's to that type.
1003 This is a step towards IPv6 support.
1005 The silc_id_get_len takes now the ID as an extra argument.
1006 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1007 both IPv4 and IPv6 based ID's.
1009 The affected files are lib/silccore/id.[ch] and other files
1010 around the tree using these routines.
1012 * Removed the ID length arguments in server from various
1013 silc_server_send_notify_* routines -> they are not needed
1016 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1018 * Fixed memory leak in silc_encode_pem_file in the file
1019 lib/silcutil/silcutil.c.
1021 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Check minor version as well in the SKE. Affected files are
1024 silcd/protocol.c and lib/silcclient/protocol.c.
1026 * Added --identifier option to the server so that an identifier
1027 can be when creating the public key for the server. Affected
1028 file is silcd/silcd.c.
1030 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1031 lib/silccrypt/silcpkcs.c.
1033 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Register default ciphers and stuff when using -C option with
1036 the server. Affected file sildc/silcd.c.
1038 * Put back the servers public key filename format, it is better
1039 than the new one. For now, the client keys are saved with the
1040 new filename format. The affected file silc/client_ops.c.
1042 * Implemented the Cipher API for the rest of the ciphers that
1043 did not implement it or implemented it the wrong way.
1045 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Register default ciphers and stuff when using the -S option
1048 in the client. Affected file silc/silc.c. Same also when
1049 creating new key pair with -C option.
1051 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * Fixed the silc_verify_public_key client operation function to
1054 save the public keys differently. The fingerprint is now
1055 used as filename and not the hostname. This way also the
1056 client keys are saved uniquely and not with hostnames. The
1057 affected file is silc/client_ops.c.
1059 * Trimmed the silc_hash_fingerprint function to remove extra
1060 whitespaces from the end of the fingerprint. The affected
1061 file is lib/silccrypt/silchash.c.
1065 * Added silc_cipher_register_default function to register all
1066 default ciphers. It can be used when configuration files
1067 does not exist and the application does not want any specific
1068 ciphers in any specific order.
1070 The SilcDList is now used as silc_cipher_list dynamically
1071 allocated cipher list. Removed the static list all together
1072 and now all ciphers must be allocated to the dynamic list.
1073 The silc_cipher_alloc routine was changed to check only the
1076 All silc_cipher_* routines that used to return int returns
1079 The affected files lib/silccrypt/silccrypt.[ch].
1081 * The same thing was done to silc_hash_* as for silc_cipher_*
1082 routines. Affected files lib/silccrypt/silchash.[ch].
1084 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1085 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1086 Added also silc_pkcs_[un]register[_default] functions.
1087 Removed the data_context from the PKCS API.
1089 * Added silc_hmac_register_default function to register default
1090 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1091 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1092 to unregister all hmacs at once.
1094 * Register the default ciphers, hash functions, PKCSs and HMACs
1095 if client's configuration file does not exist. The affected
1098 * The client did not load the hash functions from the SIM
1099 modules at all. Added support for this. Affected file is
1100 silc/clientconfig.c.
1102 * When decoding public key with silc_pkcs_public_key_decode, check
1103 the supported algorithm only if PKCS are registered. Affected
1104 file lib/silccrypt/silcpkcs.c. The same was done with the
1105 silc_pkcs_private_key_decode.
1107 * Fixed the SILC List routines to keep the list always in order.
1108 It used to change the list's order when traversing the list but
1109 not it preserves the order. Affected file lib/trq/silclist.h.
1111 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1113 * Added the client library to use the SilcSocketConnection's
1114 reference counter (by silc_socket_dup) to prevent the bug that
1115 the socket object may be freed underneath async operation.
1117 * The name resolv library checking fixes in the configure.in.pre.
1120 * Created new version of the protocol drafts for future
1121 development. The -03 drafts are the ones that will be changed
1122 in the trunk now and the -02 will remain as they are.
1124 * Send list of CUMODE notifys to the router when announcing
1125 the channel users to the router. Affected file silcd/server.c.
1126 If the router receiving channel founder CUMODE for a channel
1127 that already has channel founder it will send CUMODE notify
1128 to the sender to remove the channel founder rights from the
1129 announced client. Affected file silcd/packet_receive.c.
1131 * The CUMODE notify may now use Server ID as well as the entity
1132 who changes the mode. Updated protocool specs.
1134 * Updated INSTALL and README files.
1136 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1138 * New web pages in the http://silc.pspt.fi. The pages was
1143 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1145 * Implemented the [DenyConnectin] config section in the server.
1146 Added silc_server_config_denied_conn to check whether incoming
1147 connection is denied. Affected file silcd/serverconfig.[ch].
1149 * Do not check the ports when checking the incoming configuration
1150 data if the port is 0, meaning any. Affected file is
1151 silcd/serverconfig.c.
1153 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1155 * Fixed buffer overflow in silc_string_compare in the file
1156 lib/silcutil/silcutil.c.
1158 * Fixed double free in silc_server_command_leave in the file
1161 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1163 * Fixed the version checking in the server. Affected file is
1166 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Fixed the configuration data fetching when accepting new
1169 connections in the server. Affected file silcd/server.c.
1171 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Added `sender_entry' argument to the function
1174 silc_server_packet_relay_to_channel so that we can check
1175 whether some destination actually belongs to the same route
1176 the sender belongs (ie, we must not resend the packet to the
1177 sender). Affected file silcd/packet_send.[ch].
1179 * Added `servername' field to the SilcClientEntry in the server
1180 to hold the name of the server where client is from. Affected
1181 file is silcd/idlist.h.
1183 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1185 * Moved the channel message encrypting in the router betwen
1186 router connections from silc_server_channel_message to the
1187 silc_server_packet_relay_to_channel since we want to check
1188 whether we have anybody channel before encrypting anything.
1189 Affected files silcd/packet_[receive/send].c.
1191 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Fixed the [AdminConnection] server config section to support
1194 multiple entries. Affected file silcd/serverconfig.c.
1196 * Added support into the server to check the validity of the
1197 incoming connection before executing any KE or authentication
1200 * The connection configuration is now saved to the KE and
1201 connection auth protocol contexts and not fetched anymore in
1202 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1204 * The local hosts listenning address and port is also resolved
1205 now when starting the server. We want to have the socket object
1206 to include the real address and port for the listener. Added
1207 new function silc_net_check_local_by_sock into the files
1208 lib/silcutil/silcnet.[ch].
1210 * Fixed a broadcast bug in server -> do not broadcast if we
1213 * Fixed a routing bug. Do not route broadcast packets ever.
1214 Broadcast packets must be processed always and not routed since
1215 they may be destined to some other host than yourself and thus
1216 would get routed without no good reason. Affected file is
1219 * Added function silc_server_config_is_primary_route to check
1220 whether primary router connection has been configured (a router
1221 configuration that we are initiating). If there is not, we
1222 will assume that there is only two routers in the SILC network
1223 and we will use the incoming router connection as our primary
1224 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1226 * Changed the order of the broadcasting. Broadcast _after_ the
1227 packet has been processed not before. Affected file is
1230 * Fixed a [ClientConnection] parsing bug. The port was never
1231 parsed correctly thus resulting to port 0. Affected file
1232 silcd/serverconfig.c.
1234 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1235 argument and did not set the broadcast packet flag. Affected
1236 file silcd/packet_send.c. Fixed same bug in the function
1237 silc_server_send_notify as well.
1239 * If we receive NEW_ID packet for our own ID in the server, ignore
1242 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1246 * Removed the nickname from the Private Message Payload.
1247 Updated the code and the protocol specs.
1249 * Updated protocol specs for submitting to the IETF.
1251 * Tweaked the Random Number Generator a bit. Affected file
1252 lib/silccrypt/silcrng.c. Exported a new function
1253 silc_rng_[global]_add_noise which can be used to add more
1256 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Do not parse packets with different timeout when protocol
1259 is active -> may cause problem with rekey. Affected file
1262 * When server receives signoff notify it must not create
1263 new channel key if the client is on any channels since the
1264 sender of the signoff notify will create it.
1266 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Added printing of error messages during SKE protocol from the
1269 failure packet sent by server during SKE. Affected file
1272 * Removed the client's failure_callback handling with timeout
1273 and handle it immediately when received.
1275 * The SKE library returned wrong type in SUCCESS and FAILURE
1276 packets. They must be 32 bit MSB not 16 bit MSB.
1278 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1280 * Ok, rewrote the logic of the re-key and now it seems to work.
1281 I tested it on high traffic with frequent re-keys without
1282 problems. Added hmac_receive (and renamed hmac to hmac_send)
1283 in SilcClientConnection in lib/silcclient/client.h and
1284 in SilcIDListData in silcd/idlist.h. Also, removed the
1285 SilcPacketParserContext's cipher and hmac fields as they are
1286 not needed anymore and actually caused some problems when
1287 the ciphers and hmac's changed underneath the packet parser.
1289 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * If re-key protocol is active then process the incoming packets
1292 synchronously since we must assure that icoming packets encrypted
1293 with the old key is processed before the new keys is set to
1294 use. This is true other packets than for REKEY packets.
1295 Affected file silcd/server.c. The same was done to client library
1296 as well, affected file lib/silcclient/client.c.
1298 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * Fixed bug in client and server to accept the force send if
1301 the packet is send from silc_[server/client]_packet_process
1302 function. Otherwise the packets are never delivered, oops.
1304 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1306 * Disable force sending of packets when REKEY protocol is active.
1307 We must assure that no packet is sent directly when rekey is
1308 performed. All packets must be sent through packet queue.
1309 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1310 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1311 function is silc_[server/client]_packet_send_real to check
1314 * Replaced the SIM paths from example config files to
1315 /usr/local/modules. Also, make install creates now
1316 /usr/local/silc/logs directory to hold all the SILC server
1319 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1321 * Made the configure.in.pre work on Solaris. Patch by salo.
1323 * Made all ciphers compatible with non-x86 machines. Defined
1324 CBC mode macros into lib/silccrypt/ciphers_def.h.
1326 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1328 * Fixed the make install.
1330 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * When MAC computation fails the silc_packet_decrypt returned 0
1333 even though it was supposed to return -1. Fixed this. The
1334 affected file is lib/silccore/silcpacket.c.
1336 * Do not replace the config files in /etc/silc (in make install)
1337 if they already exist. Affected file ./Makefile.am.
1339 * Do not send re-key packets immediately but through packet queue.
1340 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1342 * Changed silc_net_check_host_by_sock to return FALSE if the
1343 IP/DNS could not be resolved. Though, it returns the IP address
1344 now even if it could not resolve it (but returns also FALSE).
1345 Affected file lib/silcutil/silcnet.[ch].
1347 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Added silc_pkcs_decode_identifier to decode the public key's
1350 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1351 Added also silc_pkcs_free_identifier. Added also new context
1352 SilcPublicKeyIdentifier.
1354 * Added -S option to the silc client. It is used to dump the
1355 contents of the specified public key file.
1357 * Changed the PKCS api to return the public key length when
1358 setting the public key.
1360 * Fixed a fatal bug in the public and private key file loading.
1361 Affected file lib/silccrypt/silcpkcs.c.
1363 * Execute the packet parsing for client with zero (0) timeout
1364 if the protocol is active. Affected file silcd/server.c.
1366 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Made the key generation options to the silcd program. Added
1369 -C option, equivalent to client's option.
1371 * Added new [ServerKeys] config section to the server. It
1372 configures the server's public and private key.
1374 * Defined generic Public Key Payload into the protocol
1375 specification to send specific type of public keys and
1378 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1379 public key or certificate.
1381 * Implemented the GETKEY command to the server and to the
1382 client library and on user interface.
1384 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1386 * Made preliminary `make install' work.
1388 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Added SilcServerRekey context into silcd/idlist.h.
1392 * Added the PFS support as defined in the specification to the
1393 SKE protocol. Affected files lib/silcske/*.c.
1395 * Added `ske_group' field to the SilcServerRekey context to hold
1396 the number of the SKE group that is used with PFS in re-key.
1397 Affected file silcd/idlist.h.
1399 * Added PFS re-key support to the server. Affected file is
1402 * Added silc_protocol_cancel to cancel execution of the next
1403 state of the protocol. Affected file is
1404 lib/silccore/silcprotocol.[ch].
1406 * Added the re-key support with and without PFS to the client
1407 library. Re-key is performed once in an hour, by default.
1409 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1410 Added silc_client_rekey_callback and silc_client_rekey_final.
1411 Affected files are lib/silcclient/protocol.[ch] and
1412 lib/silcclient/client.[ch].
1414 * Removed the `hmac_key' and `hmac_key_len' fields from the
1415 SilcClientConnection structure; not needed. Affected file is
1416 lib/silcclient/client.h.
1420 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1422 * Do not ask whether user wants to use the negotiated private key
1423 for private messages, just use it. Affected file is
1424 silc/local_command.c.
1426 * Added `send_enc_key' and `enc_key_len' fields to the
1427 SilcIDListData structure since they are needed in the re-key
1428 phase. Affected file is silcd/idlist.[ch].
1430 * Implemented the simple re-key protocol into the server.
1431 Affected files silcd/server.c and silcd/protocol.[ch]. The
1432 re-key will be performed once in an hour, by default.
1434 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1435 Added silc_server_rekey, silc_server_rekey_callback and
1436 silc_server_rekey_final.
1438 * Removed Tunneled flag from the protocol. Updated the code
1439 and the specifications.
1441 * Adde `pfs' field to the SilcIDListData to indicate whether
1442 the PFS is to be performed in the re-key. Affected file is
1445 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1448 int64 of at least the xintXX size. If void * is less that 4
1449 bytes uint32 * will be used. Defined bool as boolean.
1451 * Changed _ALL_ unsigned long and unsigned int to uint32,
1452 unsgined short to uint16 in the source tree.
1454 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1455 not handle clients that has entry->data.registered == FALSE.
1456 They are not in the network anymore. Affected file is
1459 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1461 * Implemented the sending of the SERVER_SIGNOFF notify in the
1462 server. Affected file is silcd/server.c.
1464 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1465 Added also silc_notify_payload_encode_args into the
1466 lib/silccore/silcnotify.[ch].
1468 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1469 Affected file silcd/packet_receive.c.
1471 * Implemented the SERVER_SIGNOFF notify handling in the client
1472 library. Affected file lib/silcclient/client_notify.c. Also,
1473 implemnted the printing of the SERVER_SIGNOFF info to the
1474 application. Affected file silc/client_ops.c.
1476 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1477 if the deleting was successful. Affected file silcd/idlist.[ch].
1479 * Added support for public key authentication in the connection
1480 authentication protocol in the client library. Affected file
1481 lib/silcclient/protocol.c.
1483 * Changed the server's silc_idlist_get_clients_by_* interface
1484 to support already allocated array so that new entries may be
1485 added to pre-allocated array. Affected file silcd/idlist.[ch].
1486 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1487 and command replies.
1489 * All command reply functions in the server now calls the
1490 pending command callback even if error occured. This way the
1491 error will be delivered to the client as well. Affected files
1492 silcd/command.c and silcd/command_reply.c.
1494 * Fixed INFO command to return local server's info if no server
1495 was provided. Affected file lib/silcclient/command.c.
1497 * Removed RESTART command for good. Updated the code and the
1500 * Rewrote parts of the task system. It is a bit simpler now.
1501 Removed unsued task priorities. The affected files are
1502 lib/silcutil/silctask.[ch].
1504 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Moved the USERS printing from the library to the application.
1507 Affected files lib/silcclient/command.c and silc/client_ops.c.
1509 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Added channel key re-key support. The re-key is perfomed
1514 only by the router and is done once in an hour. Added `rekey'
1515 field to the SilcChannelEntry in the server. Affected files
1516 silcd/server.c and silcd/idlist.h.
1518 * Added silc_task_unregister_by_context into the file
1519 lib/silcutil/silctask.[ch].
1521 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Added SILC_UMODE_GONE mode to indicate when the client is not
1524 present in the SILC network. Added also support to the local
1525 command AWAY that will set this mode. Added support of showing
1526 "xxx is gone" in WHOIS command. The USERS command shows the
1527 gone status as well.
1529 * Fixed setting server and router operator privileges in the
1530 server's UMODE command. Affected file silcd/command.c.
1532 * Merged the SKE KE1 and KE2 payloads into one payload. The
1533 new KE payload is equivalent to the old KE2 payload.
1535 Cleaned up the SKE Start Payload parsing. It now uses the
1536 simple buffer unformatting to do the parsing. A lot faster
1539 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1540 to the SKE that is used to indicate whether both of the SKE
1541 parties should perform authentication. By default only the
1542 responder performs authentication. By setting this flag also
1543 the initiator must do authentication. By default it is unset
1544 since in normal SKE case, client to server connection, only
1545 the responder should do authentication. When doing SKE between
1546 two clients both should perform authentication. Updated the
1547 code and the protocol specs.
1549 * A little fix to IDENTIFY command in the server. Search the
1550 client first by hash not nickname. Affected file is
1553 * Fixed the silc_client_close_connection to support closing
1554 the client to client connections wihtout deleting too much
1555 data. Affected file lib/silcclient/client.c.
1557 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1558 are received if protocol used to be active but is not anymore
1559 the application would crash due to NULL pointer dereference.
1560 Affected files silcd/server.c and lib/silcclient/client.c.
1562 * Added `hash' field to the SilcClientConnection to include
1563 the hash function negotiated in the SKE protocol.
1565 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1566 to set the channel founder authentication data. A client can
1567 claim the founder rights later by providing the authentication
1568 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1569 This way the channel founder can regain the channel founder
1570 privileges even it is left the channel. This works only on
1571 local server and the client must be connected to the same
1572 server to be able to regain the founder rights. Updated the
1573 protocol specs accordingly.
1575 Added support to the CMODE command in the client to set the
1576 founder auth data. Read the README to see how to set it.
1578 Added support to the CUMODE command to claim the founder
1579 rights. Read the README to see how to do it.
1581 Added support for the founder authentication to the Channel
1582 Entry in the server. Affected file silcd/idlist.h.
1584 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1585 server's CMODE command. Affected file silcd/command.c.
1587 * Added the following new functions into lib/silccore/silcauth.[ch]:
1588 silc_auth_get_method and silc_auth_get_data.
1590 * The server now saves the remote hosts public key to the
1591 SilcIDListData pointer. Affected file silcd/protocol.c.
1593 * The normal server now does not remove the channel entry from
1594 the cache if the founder authentication data is set. It used
1595 to remove it if the founder was the last one on the channel on
1596 the server and left the channel. The auth data is saved and
1597 if the channel is re-joined later the old entry is used with
1598 the old auth data. Affected files silcd/command_reply.c and
1601 * Removed the `pkcs' field from the SilcIDListData structure
1602 in the server; it is not used. Affected file silcd/idlist.h.
1604 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1606 * Fixed packet processing on slow links. Partial packets were
1607 never re-processed because the incoming data buffer was cleared
1608 by the application. Application must not directly clear the
1609 sock->inbuf, the packet processing routines handle it. Fixed
1610 this in client library and in server.
1612 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * Fixed the WHOIS and IDENTIFY send reply function to really
1615 check whether to send list or just one entry. Affected file
1618 * Cleaned up the LEAVE command's channel key distribution. The
1619 affected file silcd/command.c.
1621 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1622 can enforce the channel mode as well. In that case the ID
1623 includes the ID of the server. The code now enforces the
1624 mode change if the router have different mode than the server.
1626 * The notify client operation with CMODE_CHANGE notify can now
1627 return NULL client_entry pointer if the CMODE was not changed
1628 by client. Application must check for this.
1630 * Added <Server ID> argument to INFO command to support server
1631 info fetching by Server ID.
1633 * Added silc_server_announce_get_channel_users to get assembled
1634 packets of channel users of the specified channel. Affected
1635 file silcd/server.[ch].
1637 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1638 was freed underneath the ID Cache.
1640 * Re-announce clients when the server received CHANNEL_CHANGE
1641 notify from the router. Affected file silcd/packet_send.c.
1643 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1646 crashed since it did not handle the fact that there is no cipher
1647 called "3" and didn't check the error condition. Now fixed.
1649 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1650 flag. It can be used to send message requests.
1652 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1654 * Implemented the RESTART command in the client.
1656 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1657 notice type messages. Added notice printing to the user
1660 * The channel keys are not re-generated if the channel's mode
1661 is PRIVKEY, ie private key on the channel exists. Affected
1662 files silcd/server.c and silcd/command.c.
1664 * Fixed a little bug in channel message delivery when channel
1665 private keys are set in the server. Affected file is
1666 silcd/packet_send.c.
1668 * Changed the setting on channel->on_channel = TRUE from the
1669 silc_client_save_channel_key to the JOIN command reply. The
1670 key payload is not received if the private channel key is set.
1671 Affected file lib/silcclient/command_reply.c and the
1672 lib/silcclient/client_channel.c.
1674 * When the CMODE_CHANGE notify is sent and the channel private
1675 key mode is removed the channel key must be re-generated in
1676 other cells as well. Added this support for the router in the
1677 silcd/packet_receive.c.
1679 * Added new local command NOTICE to send notice message on
1680 channel. Affected file silc/local_command.[ch].
1682 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Added new local command ME to the client. It is used to send
1685 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1686 some action. Affected file silc/local_command.[ch].
1688 * Changed channel_message and private_message client operations
1689 to deliver the message flags to the application. Added also
1690 the `flags' arguments to the silc_client_send_channel_message
1691 and silc_client_send_private_message functions. Affected file
1694 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Redefined the Private Message Payload to support private message
1697 keys and to support the new private message flags. Updated
1698 the protocol specs. Flags makes it possible to have for example
1699 CTCP style messages.
1701 * Added new type SilcPrivateMessagePayload and defined an API
1702 for it in the lib/silcclient/silcprivate.[ch].
1704 * Tested private message private keys successfully. Tested the
1705 private message key set, unset and list commands with the new
1708 * Redefined the Channel Message Payload to include the channel
1709 message flags (equal with private message flags) to support
1710 for example CTCP style messages.
1712 * Defined some of the message (for channel and private message)
1713 flags. Updated the protocol specs and added the flags to the
1714 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1716 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Added SilcKeyAgreementStatus type to the key agreement routines
1719 to indicate the current status and error if one occured.
1720 The status types are defined in the lib/silcclient/silcapi.h.
1722 * Added new local command KEY that is used to set and unset private
1723 keys for channels, set and unset private keys for private messages
1724 with remote clients and to send key agreement requests and
1725 negotiate the key agreement protocol with remote client. The
1726 key agreement is supported only to negotiate private message keys,
1727 it currently cannot be used to negotiate private keys for channels,
1728 as it is not convenient for that purpose.
1730 * Fixed a minor pending callback setting bug in the function
1731 silc_client_get_client_by_id_resolve, now the function works.
1732 Affected file lib/silcclient/idlist.c.
1734 * Added function silc_net_get_local_port to get local bound
1735 port by socket. Added to lib/silcutil/silcnet.[ch].
1737 * Added `sockets' and `sockets_count' fields to the SilcClient
1738 object. They hold the sockets of the listenning sockets in
1739 the client. Listenning sockets may be for example the key
1740 agreement server. Affected file lib/silcclient/client.[ch].
1741 Added functions the silc_client_add_socket and the
1742 silc_client_del_socket. They are exported to the application
1745 * Added ~./silc/clientkeys to support other client's public keys.
1747 * Renamed verify_server_key client operation to verify_public_key
1748 and added one argument to indicate the type of the connection
1749 (server, client etc.).
1751 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Added silc_server_connection_auth_request to handle the
1754 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1755 silcd/packet_receive.[ch].
1757 * Added silc_server_send_connection_auth_request into the
1758 silcd/packet_send.c to send the connection auth request packet.
1760 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1763 * Fixed the public key authentication in responder side in the
1764 server. The `auth_data' pointer includes the SilcPublicKey
1765 not the path to the public key. Affected file silcd/protocol.c.
1767 * Implemented the public key authentication in the initiator side
1768 in the server. Affected file silcd/protocol.c.
1770 * Removed the [RedirectClient] config section from the server
1771 configuration. Is not needed and I don't want to implement it.
1773 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Cleaned up the CMODE command in the server. It now works
1776 correctly and supports all the modes defined in the protocol.
1777 Affected file is silcd/command.c.
1779 * Added `hmac_name' field to the SilcChannelEntry in the server
1780 to hold the default HMAC of the channel. It can be set when
1781 creating the channel (with JOIN command). Affected files
1784 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1785 type to indicate the change of the current cipher and hmac
1786 on the channel. Client can safely ignore the <cipher> argument
1787 (if it chooses to do so) since the CHANNEL_KEY packet will
1788 force the channel key change anyway. The <hmac> argument is
1789 important since the client is responsible of setting the new
1790 HMAC and the hmac key into use.
1792 * Fixed the CMODE command in the client library as well.
1794 * Tested CMODE command in router environment successfully.
1796 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Show the version of the remote client (or server) when connecting
1799 to the server. It is logged to the log file. Affected file
1800 is silcd/protocol.c.
1802 * Fixed the KILLED notify handling in the client library. The
1803 client must be removed from all channels when receiving the
1806 Also, do not remove the client entry when giving the KILL
1807 command but when the KILLED notify is received.
1809 * Removed silc_idlist_find_client_by_nickname from the server.
1810 Not needed anymore. Affected files silcd/idlist.[ch].
1812 * Implemented the CHANNEL_CHANGE notify type handling to the
1813 server. Affected file silcd/server.c.
1817 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Added silc_server_send_notify_invite to send the INVITE
1820 notify between routers.
1822 * Implemented the INVITE command correctly to the server.
1824 * Implemented the INVITE notify type handling in the server.
1826 * Implemented the INVITE command to the client library and on the
1829 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Added function silc_server_get_client_resolve to find the
1832 client entry by ID from all ID lists and then resolve it
1833 (using WHOIS) if it cannot be found. Affected file is
1836 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1838 * Implemented the BAN command to the client library.
1840 * The JOIN command in the server now checks the invite list
1843 * Changed the silc_command_reply_payload_encode_va and the
1844 silc_command_payload_encode_va to support that if argument is
1845 NULL it ignores and checks the next argument. Affected file
1846 lib/silccore/silccommand.c.
1848 * Added silc_server_send_notify_ban to send the BAN notify
1849 type between routers.
1851 * Chaned the silc_notify_payload_encode to support that if
1852 argument is NULL it ignores and checks the next argument.
1853 Affected file lib/silccore/silcnotify.c.
1855 * Tested ban lists in router environment successfully.
1857 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Implemented BAN command to the server, in silcd/command.[ch].
1861 * Removed the BAN and INVITE_LIST modes from the CMODE command
1864 * Added function silc_string_match to regex match two strings.
1865 Affected files lib/silcutil/silcutil.[ch].
1867 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Redefined parts of the SilcChannelEntry in the server to support
1870 the new ban and invite lists.
1872 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Redefined the INVITE command. The same command can be used to
1875 invite individuals to the channel but also to manage the invite
1876 list of the channel (to add to and remove from the invite list).
1877 Updated the protocol specs.
1879 * Added new command SILC_COMMAND_BAN that can be used to manage
1880 the ban list of the channel. Updated the protocol specs.
1882 * Removed the channel modes: the SILC_CMODE_BAN and the
1883 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1884 in the CMODE command. The equivalent features are now available
1885 using INVITE and BAN commands. Updated the protocol specs.
1887 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1888 in the network about change in the current ban list. The notify
1889 type is not used by the client.
1891 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1892 support the invite lists.
1894 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Added new function silc_string_regexify that converts string
1897 including wildcard characters into regex string that can
1898 be used by the GNU regex library. Added into the file
1899 lib/silcutil/silcutil.[ch].
1901 Added silc_string_regex_combine to combine to regex strings
1902 into one so that they can be used as one regex string by
1903 the GNU regex library. Added into the file
1904 lib/silcutil/silcutil.[ch].
1906 Added silc_string_regex_match to match two strings. It returns
1907 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1909 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1911 * Imported GNU regex to the soruce tree into lib/contrib.
1912 Fixed some compiler warning from the regex.c.
1914 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Fixed MOTD command in the server to work in router environment.
1918 * Fixed the MOTD command in the client library to support
1919 the server argument in the command.
1921 * Added `nickname_len' argument to the silc_idlist_add_client
1922 in the server, as the `nickname' argument may be binary data
1925 * Added silc_idlist_get_channels to return all channels from
1928 * Implemented LIST command to the server. Affected file is
1931 * Implemented the LIST command to the client library and on the
1934 * Added [<user count>] argument to the LIST command reply.
1935 With private channels the user count is not shown.
1937 * Updated TODO and README.
1939 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1941 * The client entry's data.registered must be TRUE even with
1942 global client entry on global client list. The data.registered
1943 is used to check whether the client is anymore in the network,
1944 for example with WHOWAS command so it must be valid.
1946 * Fixed the WHOWAS command in the server. It now actually works
1947 in router environment. Added function into silcd/command_reply.c
1948 silc_server_command_reply_whowas_save.
1950 * Added silc_idlist_purge function to the silcd/idlist.c
1951 to periodically purge the ID Cache.
1953 * Fixed INFO command in the server. It works now in router
1954 environment. Added <server name> argument to the INFO command
1955 reply. Updated the protocol specs.
1957 * Fixed minor bug in silc_idcache_purge to not purge if the
1958 expire value is zero.
1960 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1961 they were buggy because of the WHOWAS information.
1963 * Fixed local command MSG to handle the async resolving of
1964 the remote client properly. It used to fail the first MSG.
1965 Affected file silc/local_command.c.
1967 * Added `data_len' field to SilcIDCache context.
1969 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Update TODO. Todo in commands in the server.
1973 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1975 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1976 used by routers as broadcast packet to inform other routers
1977 about the changed user mode.
1979 Implemented the notify handling in the server. Affected file is
1980 silcd/packet_receive.c. Added the function
1981 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1983 * Added new generic Channel Payload and deprecated the New Channel
1984 Payload. The New Channel Payload is now the generic Channel
1987 * Added new argument `mode' to the silc_server_send_new_channel
1988 as it is required in the Channel Payload now.
1990 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1991 and created a new and real SilChannelPayload to represent the
1992 new generic Channel Payload. Implemented the encode/decode
1993 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1995 * Added silc_server_get_client_channel_list to return the list
1996 of channels the client has joined for WHOIS command reply.
1997 Affected file silcd/server.[ch].
1999 * Implemented the channel list sending in the WHOIS command reply
2000 in server and in the client.
2002 Implemented the channel list displaying on the user interface
2003 as well. Affected file silc/client_ops.c.
2005 * Added silc_channel_payload_parse_list to parse list of Channel
2006 Payloads. It returns SilcDList list of SilcChannelPayloads.
2007 Client for example can use this function to parse the list of
2008 channels it receives in the WHOIS command reply. The caller
2009 must free the list by calling silc_channel_payload_list_free.
2010 Affected files lib/silccore/silcchannel.[ch].
2012 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Added one new argument <user mode> to the WHOIS command reply
2015 to return the mode of the user in SILC. Updated the protocol
2018 Implemented it to the server and client.
2020 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Fixed the mode printing on the user interface on joining.
2023 Affected file silc/client_ops.c.
2025 * Implemented the UMODE command and user modes in general to the
2026 client library and to the user interface.
2028 * Implemented the UMODE command to the server.
2030 * The server now sends UNKNOWN_COMMAND error status if client sends
2031 unknown command. Affected file silcd/command.c.
2033 * All server commands now handle the command identifier the right
2034 way when sending the command reply to the client. The client can
2035 use to identify the command replies with the identifier.
2037 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2039 * Added silc_server_get_client_route to resolve the route to
2040 the client indicated by the client ID. Affected file is
2043 * Added silc_server_relay_packet as general function to relay
2044 packet to arbitrary destination. This deprecates functions
2045 like _send_private_message_key, _relay_notify etc. Affected
2046 file is silcd/packet_send.[ch].
2048 Removed silc_server_send_key_agreement,
2049 silc_server_send_private_message_key and
2050 silc_server_packet_relay_notify functions from the file
2051 silcd/packet_send.[ch].
2055 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2056 server. Affected file silcd/packet_receive.[ch].
2058 * Implemented the KILL command to the client. Implemented the
2059 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2060 Affected files lib/silcclient/command[_reply].c and
2061 lib/silcclient/client_notify.c. Implemented the KILL notify
2062 printing in the user inteface.
2064 * Fixed a lot silc_parse_nick memory leaks from the client
2065 library in the file lib/silcclient/command.c.
2067 * Changed the silc_server_send_notify_on_channels's `sender'
2068 argument from SilcSocketConnection to SilcClientEntry to
2069 check the sender as entry and not as connection object and not
2070 to send to the client provided as argument. The affected file
2071 is silcd/packet_send.[ch].
2073 * The notify packets that are destined directly to the client used
2074 to not to be processed by the server. Now changed that and the
2075 server processes all notify packets. After relaying the packet
2076 to the client the notify packet is processed in the server.
2078 * The silc_server_free_client_data now checks whether there is
2079 pending outgoing traffic for the client and purges the data to
2080 the network before removing the client entry.
2082 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2085 an client is killed from the SILC Network. Updated the protocol
2088 Added new function silc_server_send_notify_killed to the
2089 silcd/packet_send.[ch].
2091 * Added function silc_server_packet_relay_notify to relay notify
2092 packets that are destined directly to a client. In this case
2093 the server does not process the notify packets but merely relays
2094 it to the client. Affected file silcd/packet_send.[ch].
2096 Added also silc_server_packet_process_relay_notify to check
2097 whereto relay the notify. Affected file is
2098 silcd/packet_receive.[ch].
2100 * Implemented the KILL command to the server.
2104 * Added the backup schema desgined last fall to the protocol
2105 specs for everyone to see. The specification is in the
2106 *-spec-xx.txt draft and the packet type definitions for the
2107 backup routers is in *-pp-xx.txt draft. Thusly, added also
2108 new packet type SILC_PACKET_CELL_ROUTERS.
2110 * A big security problem in the implementation discovered. The
2111 signoff of an client did not cause new channel key generation
2112 which it of course should've done. The channel keys must be
2113 always re-generated when client leaves (or signoffs) the channel.
2114 The silc_server_remove_from_channels funtion now handles
2115 the channel key re-generation.
2117 * Added `sender' argument to the silc_server_send_notify_on_channels
2118 to not to send the client provided as argument. Affected file
2119 silcd/packet_send.[ch].
2121 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * Implemented OPER and SILCOPER commands into the server and
2126 * Added silc_auth_verify and silc_auth_verify_data to verify
2127 the authentication directly from the authentication payload.
2128 It supports verifying both passphrase and public key based
2129 authentication. Affected file lib/silccore/silcauth.[ch].
2131 * Added `hash' field to the SilcIDListData structure. It is the
2132 hash negotiated in the SKE protocol. Affected file is
2135 * Slight redesigning of the SilcAuthPayload handling routines.
2136 Do not send SilcPKCS but SilcPublicKey as argument.
2138 * Implemented the public key authentication support to the
2139 serverconfig. The public key is loaded from the provided path
2140 and saved as authentication data to void * pointer. Thus,
2141 changed the unsigned char *auth_data to void *auth_data;
2143 * Fixed SHUTDOWN command to send the reply before the server
2144 is shutdown. :) Affected file silcd/command.c.
2146 * Fixed fatal bug in CONNECT command. The hostname was invalid
2147 memory and server crashed. Affected file silcd/command.c.
2149 * Fixed fatal bug in CLOSE command. The server_entry became
2150 invalid but was referenced later in the command. Affected file
2153 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2155 * Fixed fatal bug in failure packet handling. Server ignored
2156 the failure and thus crashed when it came.
2160 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2163 that the command may be executed only once in (about) 2 seconds.
2164 The old SILC_CF_LAG flag is same but allows command bursts up
2165 to five before limiting.
2167 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2168 server code. Various commands now includes the CF_LAG_STRICT
2169 flag to disallow any kind of miss-use of the command.
2171 * Fixed the silc_buffer_unformat to not to allocate any data
2172 if the length of the data is zero. It used to allocate the
2173 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2175 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2177 * Changed the format of AdminConnection configuration section
2178 in the server. Added username of the admin to the format.
2179 Affected files silcd/serverconfig.[ch].
2181 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2182 to return admin configuration data by host, username and/or
2185 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Implemented WHOWAS command to the server. Added the functions:
2189 silc_server_command_whowas_parse,
2190 silc_server_command_whowas_send_reply,
2191 silc_server_command_whowas_from_client and
2192 silc_server_command_whowas_from_server
2194 * Added <Client ID> argument to the WHOWAS command reply. Updated
2195 the protocol specs accordingly.
2197 * Implemented WHOWAS command and command_reply to the client
2200 Implemented the WHOWAS printing on the user interface.
2202 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Added new argument to the WHOWAS command reply, the real name.
2205 It is an optional argument. Updated the protocol specs.
2207 * Added SilcIDCacheDestructor callback that is registered when
2208 the SilcIDCache is allocated. The callback is called when
2209 an cache entry in the ID Cache expires, or is purged from the
2210 cache. Added into lib/silccore/idcache.[ch].
2212 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2213 to destruct the client entries when the cache entry expires.
2214 Other ID Cache's in server and in the client library ignores
2217 * If the ID Cache entry's `expire' field is zero then the entry
2218 never expires. Added boolean `expire' argument to the
2219 silc_idcache_add function in the lib/silccore/idcache.[ch].
2220 If it is TRUE the default expiry value is used.
2222 * Added silc_server_free_client_data_timeout that is registered
2223 when client disconnects. By default for 5 minutes we preserve
2224 the client entry for history - for WHOWAS command.
2226 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Added support to the server to enforce that commands are not
2229 executed more than once in 2 seconds. If server receives
2230 commands from client more frequently, timeout is registered
2231 to process the commands. Affected file silcd/command.c.
2232 Added new function silc_server_command_process_timeout.
2234 * Changed NICK_NOTIFY handling in client library to check that
2235 if the client's nickname was changed, so there is no need to
2236 resolve anything from the server.
2238 * Removed error printing from the WHOIS and IDENTIFY commands.
2239 If error occurs then it is ignored silently in the client library.
2240 The application, however, may map the received error to
2241 human readable error string. The application currently maps
2242 the NO_SUCH_NICKNAME error to string.
2244 * Made the command status message public to the application. Moved
2245 them from lib/silcclient/command_reply.c to
2246 lib/silcclient/command_reply.h. The application can map the
2247 received command status to the string with the
2248 silc_client_command_status_message function.
2250 * Added check to the server to check that client's ID is same
2251 as the Source ID in the packet the client sent. They must
2254 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Added dist-bzip hook to the Makefile.am to make bzip2
2257 compressed distributions.
2259 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Server now enforces the maximum length for the nickname and
2262 the channel as protocol specification dictates. 128 bytes for
2263 nickname and 256 bytes for channel name.
2265 * Moved the WHOIS printing to the application. The client libary
2266 does not print out the WHOIS information anymore, the application
2267 must do it. Renamed silc_client_command_reply_whois_print to
2268 the silc_client_command_reply_whois_save.
2270 The client's idle time is also sent to the application now, and
2271 the idle is shown on screen.
2273 * Added silc_client_command_reply_identify_save to save the
2274 received IDENTIFY entries.
2276 * Do not check for channel private keys in message sending and
2277 reception if the channel does not have the PRIVKEY mode set.
2278 Affected file lib/silclient/client_channel.c.
2280 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2283 just surfaced after chaning the JOIN procedure.
2285 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2287 * Added silc_client_get_clients_by_list to get client entries
2288 from Client ID list, that is returned for example by JOIN
2289 and USERS command replies. The application should use this
2290 function for example when JOIN command reply is received to
2291 resolve the clients already on the channel (library does not
2292 do that anymore as USERS command reply is not used in the JOIN
2293 procedure anymore). Affected files lib/silcclient/silcapi.h and
2294 lib/silcclient/idlist.c.
2296 * JOIN command reply and USERS command reply returns now SilcBuffer
2297 pointers instead of unsigned char pointers when returning
2298 the client list and mode list.
2300 * Added <Client ID> argument to the JOIN command reply, mainly
2301 for the server to identify for which client the command was
2302 originally sent. Updated protocol specs accordingly.
2304 * Added SilcDlist private_key pointer to the SilcChannelEntry
2305 in the client to support the channel private keys. Affected
2306 file is lib/silcclient/idlist.h.
2308 * Added SilcChannelPrivateKey argument to the function
2309 silc_client_send_channel_message so that application can choose
2310 to use specific private ke if it wants to. If it is not provided,
2311 the normal channel key is used, unless private keys are set.
2312 In this case the first (key that was added first) is used
2313 as the encryption key.
2315 * Implemented the support for channel private key handling.
2316 Implemented the following functions:
2318 silc_client_add_channel_private_key,
2319 silc_client_del_channel_private_keys,
2320 silc_client_del_channel_private_key,
2321 silc_client_list_channel_private_keys and
2322 silc_client_free_channel_private_keys
2324 Affected file lib/silcclient/client_channel.c.
2326 * Added the support for the private keys in the channel message
2327 sending and encryption and in the message reception and
2328 decryption. Affected funtions are
2329 silc_client_send_channel_message and silc_client_channel_message.
2331 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Added SKE's key verify callback to the client library's
2334 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2336 * Removed the statement that server (or router) must send USERS
2337 command reply when joining to the channel so that the client
2338 knows who are on the channel. Instead, the client list and
2339 client's mode list is now sent in the JOIN command reply to the
2340 client who joined channel. This is better solution.
2342 * Added function silc_server_get_users_on_channel and function
2343 silc_server_save_users_on_channel to the silcd/server.[ch].
2345 * Removed function silc_server_command_send_users from the
2348 * Do not show topic on the client library anymore. The topic is
2349 sent in the command reply notify to the application and the
2350 application must show the topic now.
2352 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Added client searching by nickname hash into the IDENTIFY and
2355 WHOIS commands in the server as they were clearly missing from
2356 them. Affected file is silcd/command.c.
2358 * Fixed a bug in private message receiving in the client library.
2359 The remote ID was freed and it wasn't supposed, now it is
2362 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Minor fix to the channel payload; allocate the data area, as it
2365 needs to be of specific length.
2367 * If the key agreement port is zero then the operating
2368 system will define the bound port. Affected files are
2369 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2371 * Added new function silc_channel_payload_decrypt into the file
2372 lib/silccore/silcchannel.[ch].
2374 * Moved the channel message etc, check from silc_packet_decrypt
2375 to applications. The library calls now a generic
2376 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2377 when the packet is either normal or special. This was done to
2378 allow more wide range of checking that was not allowed when
2379 the code was in library. Now applications can do virtually any
2380 checks to the packet and return to the library the decision how
2381 the packet should be processed. Affected files are
2382 lib/silccore/silcpacket.[ch].
2384 Added silc_server_packet_decrypt_check to the server and
2385 silc_client_packet_decrypt_check to the client library.
2387 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2388 to send with specified source and destination information.
2390 * Channel message delivery between routers was broken after the
2391 channel key distribution was fixed earlier. The channel key
2392 was used be to distributed to other routers as well which is not
2393 allowed by the protocol. Now this is fixed and channel keys
2394 really are cell specific and the channel message delivery between
2395 routers comply with the protocol specification.
2397 * Fixed various commands in server to check also the global list
2398 for the channel entry and not just the local list. The affected
2399 file silcd/command.c.
2401 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2403 * Added assert()s to buffer formatting and unformatting routines
2404 to assert (if --enable-debug) when error occurs. Affected
2405 file: lib/silcutil/silcbuffmt.c.
2407 * Changed to auto-reconnect to check whether the remote host is
2408 router and register the re-connect timeout if it is. It used
2409 to check that whether we are normal server, but router must do
2410 auto-reconnect with another router as well. Affected file
2413 * Removed the [<key len>] option from CMODE command as the cipher
2414 name decides the key length, nowadays. See the defined ciphers
2415 from the protocol specification.
2417 * Added [<hmac>] option to the CMODE command to define the HMAC
2418 for the channel. Added SILC_CMODE_HMAC channel mode.
2420 * Added [<hmac>] option for the JOIN command so that user can
2421 select which HMAC is used to compute the MACs of the channel
2424 * Added Hmac field to the Channel Message Payload. The integrity
2425 of plaintext channel messages are now protected by computing
2426 MAC of the message and attaching the MAC to the payload. The
2427 MAC is encrypted. Now, it is clear that this causes some
2428 overhead to the size of the packet but rationale for this is that
2429 now the receiver can verify whether the channel message decrypted
2430 correctly and also when private keys are set for the channel the
2431 receiver can decrypt the packet with several keys and check from
2432 the MAC which key decrypted the message correctly.
2434 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2435 lib/silccrypt/silccipher.[ch].
2437 * Added silc_hash_len to return the digest length into the
2438 lib/silcrypt/silchash.[ch].
2440 * Rewrote parts of Silc Channel Payload interface in the
2441 lib/silccore/silcchannel.[ch]. The encode function now also
2442 encrypts the packet and parse function decrypts it.
2444 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Fixed a minor formatting bug in the SKE's key material processing.
2447 It actually might have processed the keys wrong way resulting
2450 * Redefined the mandatory HMAC algorithms and added new algorithms.
2451 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2452 and hmac-md5 truncated to 96 bits. The mandatory is now
2453 hmac-sha1-96. Rest are optional (including the one that used
2454 to be mandatory). Rationale for this is that the truncated HMAC
2455 length is sufficient from security point of view and can actually
2456 make the attack against the HMAC harder. Also, the truncated
2457 HMAC causes less overhead to the packets. See the RFC2104 for
2460 * Added new [hmac] configuration section. The SKE used to use
2461 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2462 is of course wrong. The official names that must be proposed in
2463 the SKE are the ones defined in the protocol specification
2464 (hmac-sha1-96 for example). The user can configure any hmac
2465 using any hash function configured in the [hash] section. At
2466 least, the mandatory must be configured.
2468 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2470 * Added HMAC list to the SKE proposal list. It has now both
2471 hash algorithm list and HMAC list. This makes the protocol
2472 incompatible with previous versions. The SKE now seems to work
2473 the way it is supposed to work, for the first time actually.
2475 * Defined plain Hash algorithms to the protocol specification.
2478 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Implemented support for key agreement packets into the server.
2481 Added functions silc_server_key_agreement and
2482 silc_server_send_key_agreement. Other than these functions,
2483 server has nothing to do with this packet.
2485 * Added support for private message key packets into the server.
2486 Added functions silc_server_private_message_key and
2487 silc_server_send_private_message_key.
2491 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2492 called in the protocol's final callback instead in the END
2493 protocol state. This makes a little more sense and in the same
2494 time in client we can use the same protocol routines for normal
2495 key exchange and to key agreement packet handling as well.
2497 * Added to both client's and server's KE protocol context the
2498 SilcSKEKeyMaterial pointer to save the key material. We will
2499 bring the key material to the protocol's final callback by doing
2500 this. The final callback must free the key material.
2502 * Added SKE's packet_send callback into client's KE protocol
2503 context so that the caller can choose what packet sending function
2504 is used. This way we can use different packet sending when
2505 doing normal SKE when doing key agreement packet handling (in
2506 the key agreement packet handling we do not want to encrypt
2509 * Implemented the responder side of the key agreement routines
2510 in the client. The client can now bind to specified port and
2511 accept incoming key negotiation. The key material is passed
2512 to the application after the protocol is over.
2514 * Implemented the processing of incoming Key Agreement packet
2515 in the client. Added function silc_client_key_agreement to
2518 * Implemented the intiator side of the key agreement routines
2519 in the client. The client can now initiate key agreement with
2520 another remote client. The key material is passed to the
2521 application after the protocol is over.
2523 * Created client_keyagr.c to include all the key agreement
2526 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2527 SILC_TASK_CALLBACK except that it is not static.
2529 * Created client_notify.c and moved the Notify packet handling
2530 from the client.[ch] into that file.
2532 * Created client_prvmsg.c and moved all private message and
2533 private message key routines from the client.[ch] into that file.
2535 * Create client_channel.c and moved all channel message and
2536 channel private key routines from the client.[ch] into that file.
2538 * Changed silc_client_get_client_by_id_resolve to resolve with
2539 WHOIS command instead of IDENTIFY command, in the file
2540 lib/silclient/idlist.c.
2542 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Implemented the SKE's responder side to the Client library.
2546 * When FAILURE is received to the protocol do not trust it
2547 blindly. Register a timeout to wait whether the remote closes
2548 the connection as it should do it, only after that process the
2549 actual failure. This was changed to both client and server.
2551 * Added client_internal.h to include some of the structures
2552 there instead of client.h in lib/silcclient/.
2554 * Added function silc_task_unregister_by_callback to unregister
2555 timeouts by the callback function.
2557 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2559 * Some "Incomplete WHOIS info" errors has been appearing on the
2560 log files. Took away the entry->userinfo check from WHOIS
2561 reply sending. The entry->userinfo is now " " if client did not
2562 provide one. I thought this was fixed earlier but something
2563 is wrong still. Let's see if the error still appears.
2565 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2567 * Fixed a minor bug in the login when the channel key is
2568 re-generated in the server. It used to generate the key in
2569 wrong order and thus caused problems in the channel traffic.
2571 * Fixed a minor bug in channel key distsribution after
2572 KICK command. The key was not sent to the router even though
2575 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Added silc_ske_process_key_material_data as generic routine
2578 to process any key material as the SILC protocol dictates. The
2579 function is used by the actual SKE library but can be used by
2580 applications as well. This relates to the private message keys
2581 and the channel private keys since they must be processed the
2582 same way the normal SILC session keys. The protocol dictates
2583 this. Affected files: lib/silcske/silcske.[ch].
2585 Added also silc_ske_free_key_material to free the
2586 SilcSKEKeyMaterial structure.
2588 * Defined silc_cipher_set_key function to set the key for
2589 cipher without using the object's method function. The affected
2590 files: lib/silccrypt/silccipher.[ch].
2592 * Implemented silc silc_client_add_private_message_key,
2593 silc_client_add_private_message_key_ske,
2594 silc_client_del_private_message_key,
2595 silc_client_list_private_message_keys and
2596 silc_client_free_private_message_keys functions in the
2599 Added functions silc_client_send_private_message_key to send
2600 the Private Message Key payload and silc_client_private_message_key
2601 to handle incoming Private Message Key payload.
2603 * Added Cipher field to the Private Message Key payload to set
2604 the cipher to be used. If ignored, the default cipher defined
2605 in the SILC protocol (aes-256-cbc) is used.
2607 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * Removed lib/silcclient/ops.h file.
2611 Redefined parts of the SILC Client Library API. Created new
2612 file silcapi.h that deprecates the ops.h file and defines the
2613 published Client Library API. Defined also private message key
2614 API and channel private key API into the file.
2616 This is the file that the application must include from the
2617 SILC Client Library. Other files need not be included by
2618 the application anymore.
2620 * Added new key_agreement client operation callback and also
2621 defined the Key Agreement library API for the application.
2623 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2626 is used by clients to request key negotiation between another
2627 client in the SILC network. If the negotiation is started it
2628 is performed using the SKE protocol. The result of the
2629 negotiation, the secret key material, can be used for example
2630 as private message key.
2632 Implemented the Key Agreement payload into the files
2633 lib/silccore/silauth.[ch].
2635 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Redefined ciphers for the SILC protocol. Added some new ciphers
2638 and defined the key lengths for the algorithms. Changed the
2639 code accordingly. The default key length is now 256 bits.
2641 * Fixed SKE key distribution function silc_ske_process_key_material
2642 when the key length is more than 128 bits. The default key
2643 length in SILC is now 256 bits.
2645 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2646 to indicate unsupported algorithm.
2648 * Renamed rijndael.c to aes.c and all functions as well.
2650 * Fixed a long standing channel key setting bug in client library.
2651 Weird that it has never surfaced before.
2653 * Fixed bug in channel deletion. If the entire channel is removed
2654 then it must also delete the references of the channel entry
2655 from the client's channel list as the client's channel entry and
2656 the channel's client entry share same memory.
2658 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Implemented CONNECT and SHUTDOWN commands in the client.
2662 * Implemented CLOSE command to the client.
2664 * Added the function silc_idlist_find_server_by_name into the
2665 files silcd/idlist.[ch].
2667 Added the function silc_idlist_find_server_by_conn into the
2668 files silcd/idlist.[ch].
2670 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * DIE command was renamed to SHUTDOWN. Updated the both code
2675 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2676 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2678 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2681 * Added function silc_server_create_connection function to create
2682 connection to remote router. My server implementation actually
2683 does not allow router to connect to normal server (it expects
2684 that normal server always initiates the connection to the router)
2685 so the CONNECT command is only good for connecting to another
2688 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2690 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2691 or some other client was kicked from the channel.
2693 Implemented the handling of the notify type to both client
2696 Implemented silc_server_send_notify_kicked to send the KICKED
2697 notify. It is used to send it to the server's primary router.
2699 * Implemented the KICK command into server and client.
2701 * Added `query' argument to the silc_idlist_get_client function
2702 to indicate whether to query the client from server or not if
2705 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2706 to indicate that the client is not channel founder.
2710 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2712 * Removed the rng context from SilcPacketContext structure and
2713 changed that the packet routine uses the Global RNG API.
2715 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Added support for quit message that client can "leave" on the
2718 channel when it quits the SILC. It is ditributed inside the
2719 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2721 Added silc_server_free_client_data that will take the
2722 signoff message as argument.
2724 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2726 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Updated parts of the protocol specification to keep it up
2731 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2734 payloads in one packet.
2736 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2737 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2738 use now the new List flag.
2740 * Also deprecated the following packet types: REPLACE_ID,
2741 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2743 * Added list support for Notify packet in server.
2745 * Added silc_server_send_notify_channel_change to send the
2746 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2747 the silc_server_send_replace_id.
2749 * Added silc_server_send_notify_nick_change to send the
2750 NICK_CHANGE notify type. Deprecates the function
2751 silc_server_send_replace_id.
2753 * Added silc_server_send_notify_join to send the JOIN notify type.
2754 Deprecates the function silc_server_send_new_channel_user.
2756 * Added silc_server_send_notify_leave to send LEAVE notify type.
2757 Deprecates the function silc_server_send_remove_channel_user.
2759 * Added silc_server_send_notify_cmode and
2760 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2761 types. Deprecates the silc_server_send_set_mode function.
2763 * Added SERVER_SIGNOFF notify type to indicate that server has
2764 quit. This means that all clients on the channel from that
2765 server will drop. This can be also used when netsplit happens.
2767 Deprecated REMOVE_ID packet type since it is not needed anymore
2770 Added silc_server_send_notify_server_signoff to send the
2771 SERVER_SIGNOFF notify type. Deprecates the function
2772 silc_server_send_remove_id.
2774 Added also silc_server_send_notify_signoff to send the
2775 SIGNOFF notify type.
2777 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2778 SILC protocol from this day on. Changed the protocol
2779 specification as well.
2781 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2782 notify type. It is used between routers to notify about
2783 topic changes on a channel.
2785 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2788 * Partly updated the protocol specification to comply with the
2789 changes now made. It is still though a bit outdated.
2791 * The JOIN notify type now takes one extra argument <Channel ID>.
2792 The packet used to be destined to the channel but now the
2793 JOIN type may be sent as list thus it is impossible to
2794 destine it to any specific channel. By adding this argument
2795 it is again possible.
2797 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Added CREDITS file. The CHANGES and CREDITS file will appear
2800 in the distribution as well.
2802 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2805 types in the server's silcd/packet_receive.c.
2807 * Implemented CMODE and CUMODE to work in router environment.
2809 * Fixed minor encoding and decoding buglet from the
2810 lib/silccore/silcmode.c.
2812 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2815 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2817 * Changed all SilcConfigServer* and silc_config_server* to
2818 SilcServerConfig* and silc_server_config*, respectively.
2821 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Associated the ID (client or server ID) to the Authentication
2824 Payload to avoid any possibility of forging. Updated the
2825 protocol specification and the code accordingly.
2827 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * The RSA key length is now save to the RsaKey context in the
2830 key generation process in lib/silccrypt/rsa.c. The key length
2831 is now used to figure out the maximum size of the block allowed
2832 to be encrypted/signed.
2834 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2835 is equivalent to the silc_mp_mp2bin but does not allocate any
2838 * Changed silc_mp_mp2bin API to take length argument. If it is
2839 non-zero then the buffer is allocated that large. If zero, then
2840 the size is approximated using silc_mp_sizeinbase, which however
2843 * Created Global RNG API which is global RNG that application can
2844 initialize. After initializing, any routine anywhere in the
2845 code (including library) can use RNG without allocating a new
2846 RNG object. This was done to allow this sort of use of the
2847 RNG in code that has no chance to allocate RNG object. All
2848 applications currently allocate this and many routines in the
2849 library use this. Affected file lib/silccrypt/silcrng.[ch].
2851 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2852 it to use the Global RNG API.
2854 * Defined Authentication Payload into protocol specification that
2855 is used during SILC session to authenticate entities. It is
2856 used for example by client to authenticate itself to the server
2857 to obtain server operator privileges.
2859 Implemented this payload into the lib/silccore/silcauth.[ch].
2860 Implemented also routines for public key based authentication
2861 as the new protocol specification dictates.
2863 Moved definitions of different authentication methods from
2864 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2866 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2867 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2868 silc_pkcs_verify_with_hash functions into the file
2869 lib/silccrypt/silcpkcs.[ch].
2871 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * The client entry's userinfo pointer must be always valid.
2874 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2875 will fail since it requires the userinfo. Now, the userinfo
2876 is allocated as "" if actual userinfo does not exist. Actually,
2877 it must exist and it is totally Ok to drop client connections
2878 that does not announce the userinfo. However, we will make
2879 this workaround for now.
2881 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2882 to return the remote port by socket.
2884 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2887 SILC_SERVER_PENDING_EXEC and added an new macro
2888 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2889 data or when error occurs while processing the pending command.
2891 Added new argument `destructor' into silc_server_command_pending
2892 and to the SilcServerCommandPending object. This destructor is
2893 now called after calling the pending callback or if error occurs
2894 immediately. If error occurs the actual pending callback won't
2895 be called at all - only the destructor. The destructor may be
2896 NULL if destructor is not needed.
2898 All this applies for client library code as well. Similar
2899 changes were made there as well for the pending commands.
2901 In the client, the application must now allocate the
2902 SilcClientCommandContext with the silc_client_command_alloc
2905 * Added reference counter to the SilcServerCommandContext. Added
2906 function silc_server_command_alloc and silc_server_command_dup
2909 Same type of functions added to the client library for the same
2912 * Removed the cmd_ident from IDListData away since it is now
2913 global for all connections. It is the command identifier used
2914 in command sending and with pending commands. The affected file
2917 * Added reference counter to the SilcSocketConnection objecet to
2918 indicate the usage count of the object. The object won't be
2919 freed untill the reference counter hits zero. Currently only
2920 server uses this, and client ignores it. The client must be
2921 set to use this too later. The affected files are
2922 lib/silccore/silcsockconn.[ch]. Added also the function
2923 silc_socket_dup to increase the reference counter.
2925 This was mainly added because it is possible that the socket
2926 is removed underneath of pending command or other async
2927 operation. Now it won't be free'd and proper DISCONNECTING
2928 flags, etc. can be set to avoid sending data to connection that
2929 is not valid anymore.
2931 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2932 the connection. After that it sets SILC_SET_DISCONNECTED.
2933 It is, however, possible that the socket data is not still freed.
2934 The silc_server_packet_process now checks that data is not
2935 read or written to connection that is DISCONNECTED. The socket
2936 get's freed when the reference counter hits zero.
2938 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * Changed the client operation API: channel_message operation's
2941 `sender' is now the client entry of the sender, not the nickname
2942 and the `channel' is the channel entry, not the channel name.
2944 In the private_message operation the `sender' is now also the
2945 client entry of the sender not the nickname.
2947 Affected file is lib/silcclient/ops.h and all applications
2948 using the client operations.
2950 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Moved the calling of ops->connect() from connect_to_server_final
2953 into receive_new_id functin since that is the point when the
2954 client is actually allowed to send traffic to network. The
2955 affected file is lib/silcclient/client.c.
2957 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2960 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2961 (if needs broadcasting) instead of broadcasting the packets one
2962 by one which would make a burst in the network traffic.
2964 * Added `broadcast' argument to the functions in silcd/server.[ch]
2965 silc_server_create_new_channel[_with_id] to indicate whether
2966 to send New Channel packet to primary router.
2968 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Added new function into the silcd/server.[ch] files:
2971 silc_server_create_new_channel_with_id to create new channel with
2972 already existing Channel ID.
2974 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2975 lib/silccore/silcpacket.h. This packet is used t send list of
2976 Set Mode payloads inside one packet. Server uses this to set
2977 the modes for the channels and clients on those channels, that it
2978 announced to the router when it connected to it. The protocol
2979 specification has been updated accordingly.
2981 * The silc_server_new_channel did not handle the packet coming
2982 from normal server as it normally does not send that. However,
2983 when it announces its channels it does send it. Implemented
2984 the support for that.
2986 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2987 into the file lib/silccore/id.h.
2989 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Fixed memory leaks in the functions silc_idlist_del_client,
2992 silc_idlist_del_channel and silc_idlist_del_server in the file
2993 silcd/idlist.c. All of those leaked like a sieve.
2995 * Fixed some small memory leaks in the client's function
2996 silc_client_notify_by_server.
2998 * Added functions into silcd/server.c: silc_server_announce_clients,
2999 silc_server_announce_channels and silc_server_announce_server.
3000 These functions are used by normal and router server to announce
3001 to its primary router about clients, channels and servers (when
3002 router) that we own. This is done after we've connected to the
3005 These functions effectively implements the following packet types:
3006 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3007 and SILC_PACKET_NEW_ID_LIST.
3009 * Added new functions into the silcd/packet_receive.[ch]:
3010 silc_server_new_id_list, silc_server_new_channel_list and
3011 silc_server_new_channel_user_list to handle the incoming
3012 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3014 * Added support of changing Channel ID in the function
3015 silc_server_replace_id. If the server that announces a channel
3016 to the router already exists in the router (with same name but
3017 with different Channel ID), router is responsible to send
3018 Replace ID packet to the server and force the server to change
3019 the Channel ID to the one router has.
3021 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3022 client that the Channel ID has been changed by the router. The
3023 normal server sends this to the client. Client must start using
3024 the new Channel ID as the channel's ID.
3026 Implemented handling of this new type into lib/silcclient/client.c
3027 into the function silc_client_notify_by_server.
3029 * Added new function silc_idlist_replace_channel_id into the files
3030 silcd/idlist.[ch] to replace the Channel ID.
3032 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Call silc_server_command_identify_check always when processing
3035 the IDENTIFY command in silcd/command.c
3037 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3040 send keepalive packets. The packet can be sent by clients,
3041 servers and routers.
3043 Added function silc_socket_set_heartbeat into the file
3044 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3045 If not set, the heartbeat is not performed. The actual
3046 heartbeat is implemented in the low level socket connection
3047 library. However, application is responsible of actually
3050 Added silc_server_send_heartbeat to send the actual heartbeat
3051 packet into silcd/packet_send.[ch]. Server now performs
3052 keepalive with all connections.
3054 * Added silc_task_get_first function into lib/silcutil/silctask.c
3055 to return the timeout task with shortest timeout. There was a bug
3056 in task unregistration that caused problems. TODO has been
3057 updated to include that task system must be rewritten.
3059 * The client library will now resolve the client information when
3060 receiving JOIN notify from server for client that we know but
3061 have incomplete information.
3063 * Rewrote parts of silc_server_remove_from_channels and
3064 silc_server_remove_from_one_channel as they did not remove the
3065 channel in some circumstances even though they should've.
3067 * Encryption problem encountered in server:
3069 The LEAVE command used to send the Channel Key packet to the
3070 router immediately after generating it. However, the code
3071 had earlier sent Remove Channel user packet but not immediately,
3072 ie. it was put to queue. The order of packets in the router
3073 was that Channel Key packet was first and Remove Channel User
3074 packet was second, even though they were encrypted in the
3075 reverse order. For this reason, MAC check failed. Now, this
3076 is fixed by not sending the Channel Key packet immediately but
3077 putting it to queue. However, this is more fundamental problem:
3078 packets that are in queue should actually not be encrypted
3079 because packets that are sent immediately gets encrypted
3080 actually with wrong IV (and thus MAC check fails). So, packets
3081 that are in queue should be encrypted when they are sent to
3082 the wire and not when they put to the queue.
3084 However, the problem is that the current system has not been
3085 designed to work that way. Instead, the packet is encrypted
3086 as soon as possible and left to the queue. The queue is then
3087 just purged into wire. There won't be any fixes for this
3088 any time soon. So, the current semantic for packet sending
3091 o If you send packet to remote host and do not force the send
3092 (the packet will be in queue) then all subsequent packets to the
3093 same remote host must also be put to the queue. Only after the
3094 queue has been purged is it safe again to force the packet
3097 o If you send all packets immediately then it safe to send
3098 any of subsequent packets through the queue, however, after
3099 the first packet is put to queue then any subsequent packets
3100 must also be put to the queue.
3102 Follow these rules and everything works fine.
3104 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3106 * Added new function silc_server_remove_clients_by_server to
3107 remove all client entries from ID list when the server connection
3108 is lost. In this case it is also important to invalidate all
3109 client entires as they hold the invalid server entry. This
3110 fixes fatal bug when server has lost connection and will reconnect
3113 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Made some sanity checks to silc_server_daemonise like to check
3116 whether the requested user and group actually exists.
3118 * Added sanity check to SKE's silc_ske_responder_finish to check
3119 that the public and private key actually is valid.
3121 * Invalidate the client's nickname when receiving Replace ID
3122 packet and the Client ID is being replaced. This means that the
3123 server will query the nickname if someone needs it (client)
3126 * Sort the ID Cache in client library when the ID Cache data
3127 has changed (needs sorting).
3129 * Do not allow for SILC client to create several connections to
3130 several servers. The client does not support windows right now
3131 and generating multiple connections causes weird behaviour.
3133 Irssi-silc client does support windows and can handle several
3134 connections without problems, see: www.irssi.org and SILC plugin.
3136 * Fixed some places where client was added to the IDList. The
3137 rule of thumb is following (in order to get everything right):
3138 If the client is directly connected local client then the
3139 `connection' argument must be set and `router' argument must be
3140 NULL to silc_idlist_add_client function. If the client is not
3141 directly connected client then the `router' argument must
3142 bet set and the `connection' argument must be NULL to the
3143 silc_idlist_add_client function.
3145 * The funtion silc_server_packet_send_local_channel actually did
3146 not check whether the client was locally connected or not. It
3147 does that now. Fixed a bug related to LEAVE command.
3149 * Fixed Remove Channel User payload parsing bug in server's
3150 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3152 * The server's silc_server_save_channel_key now checks also the
3153 global ID list for the channel as it might not be in the local
3154 list. Fixed a bug related to LEAVE command.
3156 * Is this the end of the [<unknown>] buglet that has been lurking
3157 around for a long time? A little for loop fix in server's
3158 silc_server_command_whois_parse that is used by both IDENTIFY
3159 and WHOIS command. At least, this was a clear bug and a cause
3160 of one type of [<unknown>] buglet.
3162 * WHOIS and IDENTIFY commands call the function
3163 silc_server_command_[whois/identify]_check function even if
3164 we are not router server.
3166 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Added --with-gmp configuration option. If set the GMP
3169 is always compiled in the SILC source tree. If not set then
3170 it is checked whether the system has the GMP3 installed. If
3171 it has then the GMP won't be compiled (the system's headers
3172 and library is used), if it doesn't have it then the GMP is
3173 compiled in the SILC source tree.
3175 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Changed RSA private exponent generation to what PKCS #1
3178 suggests. We try to find the smallest possible d by doing
3179 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3180 not security fix but optimization.
3182 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Added new config entry [Identity] to fork the server and run
3185 it as specific user and group. A patch from Bostik.
3187 * Imported Dotconf configuration library into lib/dotconf.
3188 This will be used to create the SILC configuration files later.
3189 It will appear in the distsribution after this commit.
3191 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3193 * A big code auditing weekend happening. Auditing code for
3194 obvious mistakes, bugs and errors. Also, removing any code
3197 Removed files for being obsolete:
3199 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3200 inline in the file lib/silcutil/silcbuffer.h)
3202 o lib/silcutil/silcbufutil.c (the header has inline versions)
3204 Changed code to fix possible error conditions:
3206 o The buffer formatting routines now check that the destination
3207 buffer really has enough space to add the data. This applies for
3208 both buffer formatting and unformatting
3209 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3210 unformatting was changed to accomodate following rules:
3211 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3212 sent to the function while XXX_*STRING will not allocate or copy
3213 the data into the buffer. Instead it sets the pointer from the
3214 buffer into the pointer sent as argument (XXX_*STRING used to
3215 require that the pointer must be allocated already). This change
3216 makes this whole thing a bit more consistent and more optimized
3217 (note that the data returned in the unformatting with XXX_*STRING
3218 must not be freed now). The routines return now -1 on error.
3220 o Tried to find all code that use buffer_format and buffer_unformat
3221 and added return value checking to prevent formatting and
3222 especially unformatting errors and possible subsequent fatal
3225 o Changed ske->x and ske->KEY to mallocated pointers in
3226 lib/silcske/silcske.h. Fixed possible data and memory leak.
3228 o Added return value checking to all *_parse* functions. Fixed
3229 many memory leaks as well.
3231 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3232 so that buffer overflows would not happen. All code now also
3233 checks the return value as it can fail.
3235 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Added reconnection support to server if the normal server looses
3238 its connection to the router (for example if router is rebooted).
3239 The server performs normal reconnection strategy implemented
3240 to the server. Affected file silcd/server.c.
3242 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Added new packet type SILC_PACKET_SET_MODE that is used to
3245 distribute the information about changed modes (for clients,
3246 channels and clients channel modes) to all routers in the
3247 network. Updated the protocol specification accordingly.
3249 Added functions into silcd/packet_send.c and
3250 silcd/packet_receive.c: silc_server_send_set_mode,
3251 silc_server_set_mode.
3253 Added new files silcmode.[ch] into lib/silccore that implements
3254 the encoding and decoding of Set Mode Payload. Added new type
3255 SilcSetModePayload. Moved the definitions of different modes
3256 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3258 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Oops, a little mistake in server's connection authentication
3261 protocol. The protocol is not ended with FAILURE but with
3262 SUCCESS if the authentication is Ok. :) Affected file is
3265 * Implemented NICK_CHANGE notify handling in server in the file
3266 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3267 the local clients on the channel. After the changing nickname
3268 in router environment snhould work and the [<unknown>] nickname
3269 should appear no more.
3271 The silc_server_replace_id function that receives the Replace ID
3272 payload now sends the NICK_CHANGE notify type also in the file
3273 silcd/packet_receive.c
3275 * Changed WHOIS and IDENTIFY command to support the maximum amount
3276 of arguments defined in protocol specs (3328 arguments). This
3277 fixed a bug that caused problems when there were more than three
3280 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Added extra parameter, command identifier, to the
3283 silc_client_send_command so that explicit command identifier
3286 Changed that ID list routines uses specific command identifier
3287 when sending WHOIS/IDENTIFY requests to the server so that they
3288 can be identified when the reply comes back.
3290 Affected files lib/silcclient/command.[ch],
3291 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3293 * Added `sender' argument to silc_server_packet_send_to_channel
3294 to indicaet the sender who originally sent the packet to us
3295 that we are now re-sending. Ignored if NULL. Affected file
3296 silcd/packet_send.[ch].
3298 * Added some server statistics support in silcd/server_internal.h
3299 SilcServerStatistics structure and around the server code. Also
3300 send some nice statistics information when client is connecting
3303 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Fixed channel ID decoding in server's JOIN command reply in
3306 silcd/command_reply.c
3308 * Fixed braodcasting of replace ID payload to not to send it if
3309 we are standalone server in silcd/packet_receive.c.
3311 * Fixed all channel message sending routines to not to send
3312 packets to clients that has router set, since they are routed
3313 separately in the same function earlier. Affects file
3314 silcd/packet_send.c and all channel packet sending functions.
3316 * In USERS reply, res_argv[i] are not allocated, the table
3317 is allocated. Thus changed that free the table, not its
3320 * In server's whois_check and identify_check if the client is
3321 locally connected do not send any WHOIS commands - they are not
3324 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Fixed some minor bugs in client when sending WHOIS command. The
3327 arguments was in wrong order.
3329 * Removed statis function add_to_channel from server in
3330 silcd/command.c that was previously used with the joining but
3333 * Tested USERS command in router environment successfully with two
3334 routers, two servers and two clients.
3336 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Reorganized the USERS command and command reply in client library
3339 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3340 When the command is given by user we register a pending command
3341 callback that will reprocess the command after the reply has been
3342 received from the server. When reprocessing the packet we then
3343 display the information. Thus, the USERS information is displayed
3344 now in the command callback instead of in the command reply
3345 callback. The processing of the command is same as previously
3346 when server has sent the command reply in the JOINing process.
3348 * Added to USERS command in silcd/command_reply.c to join the client,
3349 we didn't use to know about, to the channel after we've created
3350 a client entry for it. Also, for clienet we did know already still
3351 check whether it is on the channel or not and add it if not.
3353 * Removed silc_server_command_join_notify as the function and its
3356 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Changed the client's pending command handling to the same as the
3359 server's pending command handling. It is also now possible to
3360 execute command reply functions from other command reply
3361 function as the function callbacks for commands and command
3362 replies are one and same. The pending commands are not static
3363 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3364 in client connection context. Thus, pending commands are server
3365 connection specific as it is convenient.
3367 Changed the function silc_client_command_pending and
3368 silc_client_command_pending_del and added new function
3369 silc_client_command_pending_check. Removed the
3370 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3373 * Added cmd_ident, current command identifier, to the client
3374 connection context in lib/silcclient/client.h to keep track on
3375 command identifiers used in command sending. Client's command reply
3376 function handling now supports the mandatory command identifiers.
3378 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3379 funtions in client to fully support pending command callbacks.
3381 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3382 as one of the arguments to the application in the command reply
3385 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3386 before first releasing SILC but came back. Now it is removed again
3387 and should come back nomore. The FORWARDED flag was used only
3388 by the JOINing procedure by forwarding the command packet to router.
3389 Now, the JOINing procedure has been changed to more generic (due
3390 to various router environment issues) and FORWARDED is not needed
3391 anymore for anything. The protocol specification is yet to be
3394 Now, removed silc_server_packet_forward from server and the flag
3395 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3397 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Renamed NAMES command to USERS command. The NAMES was named that
3400 due to historical reasons. Now it is renamed. Also, rewrote
3401 parts of the USERS command. The nickname list is not sent anymore
3402 by the server. Only Client ID and mode lists are sent in the USERS
3403 command. Changed this also to the protocol specification.
3405 The client now resolves the names and stuff after it receives
3406 the USERS list from the server when joining to the channel.
3408 * WHOIS and IDENTIFY commands has been changed to support multiple
3409 Client ID's per command. One can now search for multiple users
3410 in the network by sending only one WHOIS or IDENTIFY command.
3411 Changed the code and the protocol specifications.
3413 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3414 uses silc_server_command_whois_parse to parse the request. */
3416 * If normal server, do not parse the WHOIS and IDENTIFY requests
3417 before sending it to the router. Saves some time.
3419 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Fixed JOIN command on client library. Wrong number of arguments
3422 used to crash the client.
3424 * Added silc_server_channel_has_global function to check whether
3425 channel has global users or not.
3427 * Added silc_server_channel_has_local function to check whether channel
3428 has locally connected clients on the channel.
3430 * The silc_server_remove_from_one_channel now checks whether the
3431 channel has global users or not after given client was removed from
3432 the channel. It also checks whether the channel has local clients
3433 on the channel anymore. If it does not have then the channel entry
3434 is removed as it is not needed anymore.
3436 * The silc_server_notify now checks on JOIN notify whether the joining
3437 client is one of locally connected or global. If it is global then
3438 the channel has now global users on the channel and that is marked
3439 to the channel entry. Also, it now saves the global client to
3440 global list who is joining and JOINs it to the channel. This is
3441 for normal server, that is.
3443 Changed silc_server_send_notify_on_channel,
3444 silc_server_packet_relay_to_channel and
3445 silc_server_packet_send_to_channel check if we are normal server
3446 and client has router set (ie. global client) do not send the
3447 message to that client, as it is already routed to our router.
3449 * Implemented LEAVE notify type handling in silc_server_notify
3452 * Tested LEAVE command in router environment successfully. Tested
3453 with two routers, two servers and two clients.
3457 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3459 * Implemented SIGNOFF notify type handling in silc_server_notify
3462 * silc_server_remove_id now removes the client entry from all channels
3463 it has joined and thusly sends SIGNOFF notify type.
3465 * Rewrote the NAMES list generation in server by removing two excess
3466 loops. The lists are created now inside one loop.
3468 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * silc_server_remove_channel_user checks now also global list
3471 for channel and client.
3473 * silc_server_new_channel_user checks now both local and global
3474 list for channel and client. Fixed a bug in client id decoding.
3475 Used to decode wrong buffer.
3477 * silc_server_channel_message checks now both local and global
3478 list for channel entry.
3480 * Tested channel joining (hence JOIN) in router environment
3481 successfully. Tested with two routers, two servers and two
3484 * Tested channel message sending in router environment successfully.
3486 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Added silc_server_save_channel_key into server.[ch] to save the
3489 received channel key in Channel Key payload processing. It is
3490 also used in JOIN command reply handling.
3492 Equivalent function silc_client_save_channel_key added into
3493 client.[ch] into client library.
3495 * Changed JOIN command reply to send information whether the channel
3496 was created or not (is existing already) and the channel key
3497 payload. Changed protocol specs accordingly.
3499 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3500 the request was sent by ID and not by nickname. Crashed on
3503 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3506 now correctly save the received data.
3508 * silc_server_free_sock_user_data now notifies routers in the
3509 network about entities leaving the network.
3511 At the same time implemented functions silc_server_remove_id
3512 and silc_server_send_remove_id to receive and send REMOVE_ID
3513 packets. The packet is used to notify routers in the network
3514 about leaving entities. The ID removed will become invalid in
3517 * Added function silc_idlist_del_server into server. Removes and
3518 free's server entry from ID list.
3520 * silc_server_private_message function now checks, if we are router,
3521 that the destination ID really is valid ID, naturally.
3523 * In router when NEW_ID packet is received (for new client) the
3524 hash of the Client ID is saved in the ID Cache but the
3525 client->nickname is set to NULL, instead of putting the hash
3528 IDENTIFY command now also checks that client->nickname must be
3529 valid. If it is not if will request the data from the server who
3530 owns the client. Added new function
3531 silc_server_command_identify_check.
3533 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3534 to set the command to already allocated Command Payload.
3536 * Tested private message sending in router environment with two
3537 routers, two servers and two clients. Fixed minor bugs and now
3540 * Fixed segfault from client's NAMES command. Used to crash if
3543 * Forwarded packets must not be routed even if it is not destined
3544 to the receiver. Changed server code comply with this.
3546 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3548 * Added `require_reverse_mapping' boolean value to ServerParams
3549 structure. If TRUE (not default) the server will require that
3550 the connecting host has fully qualified domain name.
3552 If the reverse mapping is not required and hostname could not be
3553 found the IP address is used as hostname.
3555 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Implemented version string checking to both client and server.
3558 The check is incomplete currently due to the abnormal version
3559 strings used in development version of SILC.
3561 * Changed all command functions in server to use the new
3564 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Changed char *data to unsigned char *data in ID Cache system to
3567 support binary data as ID Cache data. Changed code to support
3568 binary data in lib/silccore/idcache.c.
3570 * Renamed silc_server_packet_relay_command_reply to
3571 silc_server_command_reply as it is normal packet receiving
3572 function. Rewrote the function to accept command replys for
3573 servers and not only for clients.
3575 * Mark remote router always as registered server if we are connecting
3576 to it. Otherwise, commands sent by the router to us are ignored.
3578 * All ID List find routines now returns the ID Cache Entry pointer
3579 as well if requested.
3581 * WHOIS command works now in router environment, tested with two
3582 routers, two servers and two clients.
3584 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3585 in router environment (as it is almost equivalent to WHOIS) but
3586 hasn't been tested thoroughly. Added new functions:
3588 silc_server_command_identify_parse
3589 silc_server_command_identify_send_reply
3590 silc_server_command_identify_from_client
3591 silc_server_command_identify_from_server
3593 * Disabled route cache adding because adding two different ID's with
3594 same IP replaces the old cache entry thus giving wrong route.
3595 The entry->router->connection is always the fastest route anyway
3596 so route cache may not be needed. Of course, new routes maybe
3597 established after receiving the ID when the entry->router->connection
3598 might not be anymore the most optimal.
3600 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Add route cache for received ID for fast routing.
3604 * Added silc_server_packet_route to route received packet on router
3605 that is not destined to us.
3607 * Renamed silc_server_get_route to silc_server_route_get.
3609 * Added id_string and id_string_len fields into SilcServer to
3610 include encoded ServerID for fast comparing without excess
3611 encoding of the ID's.
3613 * Cleaned up WHOIS command on server side. Added following static
3616 silc_server_command_whois_parse
3617 silc_server_command_whois_check
3618 silc_server_command_whois_send_reply
3619 silc_server_command_whois_from_client
3620 silc_server_command_whois_from_server
3622 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3623 arguments in command replies. All command functions should be
3624 updated to use this macro.
3626 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Minor typo fixes on command reply handling on server.
3630 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Added silc_server_command_add_to_channel internal routine to add
3633 the client to the channel after router has created the channel and
3634 sent command reply to the server.
3636 * Added generic silc_server_send_command to send any command from
3639 * Use static buffer with ID rendering instead of duplicating data.
3641 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * Fixed a channel user mode bug when joining to a channel server gave
3644 everybody channel founder rights, oops.
3646 * We mark ourselves as the router of the incoming server connection
3647 if we are router ourselves. This way we can check in some packet
3648 sending functions whether it is locally connected server. For
3649 incoming router connections we put NULL.
3651 * For router sending packets locally means now always sending the
3652 packet cell wide; to local clients and local servers. For normal
3653 server sending packet locally means sending it to only local
3656 * Fixed the JOIN command to really work in router environment. If the
3657 channel is created it is always created by the router. Router is
3658 also responsible of making the initial joining to the channel,
3659 sending JOIN notify to the sending server and distributing
3660 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3661 does not exist server doesn't do anything else but forward the
3662 command to the router which performs everything.
3664 * Added silc_server_send_channel_key function to send the Channel Key
3667 * Added silc_server_create_channel_key to create new channel key. The
3668 channel key is now re-generated everytime someone joins or leaves
3669 a channel, as protocol dictates. Note: channel->key_len is the
3672 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3675 packet_receive.[ch] to separate packet sending and receiving
3676 routines. The server.[ch] now includes everything else including
3677 actual packet processing (writing and reading data) and other
3680 Renamed silc_server_private_message_send_internal to
3681 silc_server_send_private_message. The routine is still though
3682 used only to relay private messages as server does not send
3683 private messages itself.
3685 Renamed silc_server_new_channel to silc_server_create_new_channel
3686 and added new function sicl_server_new_channel that handles the
3687 incoming New Channel packet. Added also new sending function
3688 silc_server_send_new_channel to send New Channel Payload.
3690 * Added new function silc_server_notify to process incoming notify
3691 packet to the server/router. Server may then relay the notify
3692 to clients if needed.
3694 * Added new function silc_server_new_channel_user to process incoming
3695 New Channel User packet. Router will redistribute the packet and
3696 send JOIN notify to its local clients and locally connected servers
3697 if needed. Normal server will send JOIN notify to its local client
3698 on same channel when received this packet. Added also corresponding
3699 sending function silc_server_send_new_channel_user to sent the
3702 * Added boolean route argument to send_notif_to_channel and
3703 packet_send_to_channel functions to attempt to route the packet
3704 if it is TRUE and send only locally if it is FALSE.
3706 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * silc_server_replace_id now broadcasts the received replace ID
3709 packet if it is not broadcast packet already. The router must
3710 broadcast to inform other routers about changed ID.
3712 * Added backpointer to server's router into SilcServer context in
3713 silcd/server_internal.h.
3715 * Fixed silc_server_packet_broadcast to send correct broadcast
3718 * The channel key is now distributed to the local client as soon
3719 as it is received from the router (in router environment) so that
3720 no other packet may be sent for the channel until client has
3723 * silc_server_remove_channel_user now broadcasts the received
3724 Remove Channel User packet if it is not broadcast packet already.
3725 The router must broadcast to inform other routers about removed
3728 * Added users field into SilcPacketContext that is a reference count
3729 of the context. One can increase the reference count by calling
3730 silc_packet_context_dup which is now changed to just increase the
3731 reference count instead of duplicating the data. The reference
3732 count is decresed by calling silc_packet_context_free that will
3733 free the data after the reference count hits zero.
3735 For now on the packet context and everything allocated into it
3736 (including the raw packet from network) must be freed by calling
3737 the new silc_packet_context_free function. Added also new function
3738 silc_packet_context_alloc that must be used now to allocate the
3739 context. This also means that if a routine is asynchronous from
3740 silc_[client/server]_packet_parse_type the packet context must
3741 be duplicated by calling silc_packet_context_dup. Otherwise it
3742 gets free'd after silc_[client/server]_packet_parse_type returns.
3743 Also, one must remember that if packet is duplicated then its
3744 reference count must be decresed by calling the free function as
3745 many times as it was duplicated.
3747 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3748 from both client and server.
3750 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Made joining to a channel working in router environment.
3754 * Cleaned up JOIN command on server side and create function
3755 silc_server_command_join_channel internal routine to make the
3758 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Changed silc_command_pending list to SilcDList. Also, added
3761 `ident' field to SilcServerCommandPending structure to identify
3762 the reply and to call correct callback.
3764 Added silc_server_command_pending_check function to replace the
3765 corresnponding macro. The silc_command_pending list is not
3768 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3769 to set identifier to previously allocated Command Payload. It
3770 is used to set identifier for command when resending Command
3773 * Added silc_command_payload_encode_payload to encode Command
3774 Payload buffer from SilcCommandPayload structure.
3776 * Added silc_argument_payload_encode_payload to encode Argument
3777 payload buffer from SilcArgumentPayload structure.
3779 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Changed WHOIS command to support router connection on server side.
3782 The whois request is always sent to router unless the server is
3783 standalone server. After server has received the reply from the
3784 router will it send the reply to the client.
3786 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3787 broadcast received broadcast packet. The function is used only
3788 by router. The broadcast packet is always sent to the router's
3791 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3792 render given ID to printable string, for log files for example.
3794 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Made basic router to router connections working. At least they
3797 can now connect to each other but nothing really works the way
3798 they are supposed - yet.
3800 * Added new initiator token to RouterConnection configuration
3801 file in silcd/serverconfig.[ch]. It is used to tell whether we
3802 are the initiator to the remote router or whether we'll expect
3803 the other end to connect.
3805 * Moved registering of listener task to silc_server_init, hence
3806 the server starts listenning as soon as it is run, even if it
3807 does not have connections to other routers. Let's see how well
3810 * Changed default connection retry timeouts for more suitable in
3813 * Removed cipher and such arguments from silc_idlist_add_client
3814 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3815 Added new function silc_idlist_add_data to add the keys and stuff
3818 * Added SilcIDListData structure and added it to SilcClientEntry
3819 and SilcServerEntry as their first field in the structure. This
3820 way we can explicitly cast the ID entries to the SilcIDListData
3821 structure and get common data for the entries. In past, we had
3822 to first check what type of connection it is and then cast it to
3823 correct ID entry type. Now, we can directly cast the opaque
3824 pointer to the SilcIDListData (no matter what ID entry it actually
3825 is) and get the data needed.
3827 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3830 in some circumstances even if threre were timeout tasks, though not
3831 IO tasks, but tasks anyway. Now fixed.
3833 * Defined SilcServerConnection structure to hold connection specific
3834 stuff about directly connected servers and routers. The definition
3835 is currently in silcd/server_internal.h. I thought about having
3836 a bit more important role fro this struct but for now it is used
3837 only when connecting to other server (or router actually).
3839 * Added connecting retry support in server when connecting to
3840 router(s). The retry feature implement exponential backoff
3841 algorithm. Also, added SilcServerParams structure to hold default
3842 parameters for server. For now, it include these retry settings
3843 and are hard coded. After server is moded to be as Silc Server
3844 Library this structure will be more important.
3846 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Changed client librarys channel->clients table to SilcList and
3849 changed code accordingly.
3851 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Changed client's channel table to SilcList and changed code
3854 accordingly. Also changed SilcChannelClientEntry to include back-
3855 pointer to the channel so that client entry can use that structure
3856 as list as well and we have fast cross-reference to the channel.
3857 This change dramatically decreased the complexity of channel
3858 handling with client entry and vice versa (removed one extra
3859 loop when searching for channel entry from many functions).
3861 * Changed server->sim from table to SilcDList and changed code
3864 * NAMES command can now be used from user interface. It will show
3865 the user list on the channel, neatly.
3867 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3868 Code now saves realname of the user if it becomes available.
3870 * Renamed configure.in to configure.in.pre and made ./prepare
3871 script to automatically add correct version string to
3872 configure.in which it creates from configure.in.pre.
3874 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * NAMES command reply now shows users mode with the nickname when
3879 * Moved silc_client_ch[u]mode[_char] functions from
3880 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3881 place sucks, they are utility functions and should be in some
3884 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3886 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3889 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Added TRQ (efficient deque and list library) into lib/trq. This is
3894 a very good list library that is currently used in the SILC. Defined
3895 SilcList API over the library because I didn't like the API very
3896 much. See lib/trq/silclist.h for the API and examples of how to
3897 use the API. Fixed various places in the code to use the new
3898 SilcList API. The SilcList is meant for lists that has a structure
3899 already defined as a list. It is not suitable to add just some
3900 context to the list (in TRQ, the context is the list actually).
3902 So, I defined SilcDList that can be used for the purpose where
3903 predefined list structure does not exit. This can be used as
3904 such list. Now some context just can be added to the SilcDList.
3905 Currently this list is not used in the SILC just yet, though there
3906 are a lot places where this can replace dynamically allocated
3907 tables and I will fix these places, later, to use SilcDList.
3908 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3909 and use TRQ internally).
3911 Also fixed some annoying warning messages that the original TRQ
3912 code generated. Also minor changes to TRQ's Makefile.in.
3914 * Added support for querying by Client ID to both WHOIS and
3915 IDENTIFY commands into server, as required by the protocol.
3917 * Removed method function pointers from SilcBuffer structure. They
3918 weren't used to anything and just increased the context size for
3919 no good reason. This change also made silc_buffer_alloc and
3920 silc_buffer_free functions inline functions.
3922 * Disabled command flooding detection support until it's fixed so
3923 that it accepts commands in but does not execute them more than once
3926 * Added silc_net_localhost(), to return local hostname, into
3927 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3928 that must be initialized before calling silc_client_init.
3930 * Added new function: silc_server_send_notify_on_channels to send
3931 notify messages to all channels client has joined. It is assured
3932 that the message is sent only once per client.
3934 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3935 lib/silcutil/silcutil.[ch] as silc_format function. The new
3936 function is generic and is used by server as well, not only by
3937 the logging routines.
3939 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3940 the provided version string was not acceptable. Added new function:
3941 silc_ske_check_version into lib/silcske/silcske.h. The function
3942 must be implemented by the application (client or server) and it
3943 does not reside in the SKE library. The function checks the version
3944 string remote end sent.
3946 * Added back pointers (to opaque context and to SilcSocketConnection)
3947 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3949 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3950 duplicate packet context structure.
3952 * Changed `notify' client operation to send same arguments as client
3953 receives from server except for ID's. ID's are mapped to correct
3954 ID entry and that is returned. Also, if channel entry is not sent
3955 by server but the notify is for channel the channel entry is sent
3956 to application (otherwise application doesn't know that it is for
3957 channel (library gets it from packet's Destination ID)).
3959 * Added silc_client_remove_from_channels into client library to
3960 remove a client from all channels it has joined to. Used when
3961 received SIGNOFF notify from server. Added also new function
3962 silc_client_replace_from_channels to replace old ID entry with
3963 new ID entry on all channels. Used when received NICK_CHANGE
3966 * Fixed ID Cache list handling in silc_idlist_get_client in
3967 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3968 to get (or query) client by ID.
3970 * Updated TODO list.
3972 * Added connection authentication status message defined by the
3973 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3974 support for these into the code in client and server side.
3976 * Added generic function silc_client_send_command to send any command
3977 with variable argument list. Application should use this function
3978 to send commands if the command functions provided by the library
3979 does not suite for the application's user interface needs.
3981 * Added new `failure' client operation. Application is notified about
3982 received failure packet if client is executing a protocol. In this
3983 case the protocol's execution has failed.
3985 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3986 is required by the protocol.
3988 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3989 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3992 * Added status flag to SilcSKE object to indicate realtime status
3993 of the SKE protocol.
3995 * Application receives now exactly same command reply arguments as
3996 the library receives from server. However, if ID is received the
3997 corresponding ID entry is returned to the application (eg. Client
3998 ID is mapped to correct SilcClientEntry entry and that is returned).
3999 Changed command_reply client operation due to this change.
4001 * Changed all ID's in commands and in command replys as ID Payloads.
4002 Change affected both client and server side codes.
4004 All ID's sent in SILC network (with execption of ID's in SILC
4005 Packet header) are sent in ID Payload to support variable length
4008 * Server now notifies nick changes and notifies all clients on
4009 the channels about the new nickname (about the new Client ID,
4012 * Implemented CMODE command to change channel modes. Supports all
4013 channel modes defined by the protocol specs except ban and invite
4014 lists. (Also, private channel key mode is supported but support for
4015 setting private channel key in client is missing, thus, this mode
4016 has no effect on client side (except that server requires that the
4017 client uses private channel key and normal channel traffic does not
4020 Also, invite mode works per se, but INVITE command does not work
4021 yet correctly, so you can set channel as invite only channel but
4022 inviting clients to the channel does not work (it is yet to be
4023 thought what's the best way to do it).
4025 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4026 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4027 Implemented CUMODE command to change user's mode on the channel.
4028 Supports all modes defined by the protocol specs.
4030 * Added NAMES command reply to return users modes on the channel.
4032 * Removed unnecessary and slow ciphers from lib/silccrypt.
4034 * Set SO_KEEPALIVE option to connection sockets by default.
4036 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4038 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4039 redefined the Notify Payload into protocol specs.
4041 * Added silc_id_payload_parse_id to get ID directly from raw
4044 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4047 accept searching by Client ID as well.
4049 * Added support for LEAVE and SIGNOFF notify types in client library.
4051 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4052 to parse ID Payload from raw data.
4054 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Added flags parameter into silc_ske_assemble_security_properties
4057 function in lib/silcske/silcske.[ch].
4059 * Changed notify client operation to fit better for notify messages
4060 sent by server. The notify payload received from server is now
4061 passed to the application (after parsing it to SilcNotifyPayload).
4062 It is application's responsibility to retrieve the arguments
4063 from the payload and show the message the way it wants. The message
4064 sent by server is implementation specific.
4066 * Changed public keys to comply with the protocol specification.
4067 Old public keys are not supported anymore and are not compatible.
4069 * Removed nickname from Channel Payload as the latest draft removed
4070 it. The client must resolve the nickname from the NAMES command
4071 reply received when it joined the channel.
4073 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4075 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Fixed some errors in protocol specification drafts.
4079 * Created lib/silccore/silcnotify.c to implement Notify Payload
4080 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4081 generic payloads described by protocol specifications. The file
4082 includes implementations for ID Payload and Argument Payload.
4084 * Changed Command Payload implementation to use the new Argument
4085 Payload. Changed command_xxxx_payload to command_payload_xxxx
4086 to comply with SILC coding conventions.
4088 * Added suppport for Argument Payload handling in Notify Payload
4089 implementation as protocol requires it. Added the new support
4090 into server and client lib as well.
4092 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Added support for multiple nicknames on same channel. [n] is
4095 added locally to the nickname if there are more than one same
4096 nicknames on the channel.
4098 * Server now sends all nicknames that matched WHOIS request.
4099 Client also shows the list received from server.
4101 * Added TOPIC command to client side. User can now set and show
4102 current topic on channel.
4104 * Added MOTD command to client and server. Also, server sends the
4105 motd when client connects to the server.
4107 * Changed version strings to comply ISO 8601.
4109 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Fixed protocol error handling in client library. It should now
4112 cope even if the SKE fails for some reason.
4114 * Made new protocol specification drafts for submitting to IETF.
4116 * Implemented TOPIC command to server in silcd/command.c.
4118 * Added two new notify types into lib/silccore/silcnotify.h:
4119 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4120 notify nickname change and topic setting/change on a channel.
4122 * API change of command_reply operation in client library. The
4123 application gets now the status type received from server as well.
4125 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4129 * Cras fixed and optimized the packet handling even further and
4130 it should work now. Minor change to the prototype of function
4131 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4133 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Added new function into lib/silcutil/silcschedule.[ch]:
4136 silc_schedule_with_fd to select() a specified fd. The function
4137 returns after timeout expires or data arrives or goes. The
4138 function is used by packet routines to wait that all data is
4139 received from network.
4141 * Fixed data reading from network in lib/silccore/silcpacket.c.
4142 The code now assures that all data is read from the fd and then
4143 continues packet processing. This was a bug fix since the code
4144 used to drop some data in some circumstances.
4146 * Added new function into lib/silcclient/client.[ch]:
4147 silc_client_start_key_exchange to start key exchange after
4148 connection has been established to server. The code internally
4149 now uses this funtion but its main purpose was to provide it
4150 for applications that perform their own connecting. After
4151 application has created a connection it merely calls this
4152 function to start the key exchange between client and server.
4153 The library takes care of everything else after that.
4155 Updated also lib/silcclient/README to explain the usage of
4158 * Do not send to application information that connection has
4159 been established. Application gets notified it by connect
4162 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Applied cras's patch to add silc_schedule_one function. The
4165 function runs scheduler once and returns.
4167 * Fixed the scheduler after cras messed it up. The timeout
4168 handling works now as it's supposed to work.
4170 * Added into lib/silccore/ silcnotify.h to include notify
4171 message types support. Changed silc_server_send_notify*
4172 functions, in server.[ch], to support those new notify types.
4173 Added the support for the notify types into client library,
4174 as well. Added new notify client operation into ops.h in
4177 * Changed silc_server_packet_send_to_channel to send normal
4178 packets instead of just channel message packets. The function
4179 is now used to send the notify packets to channels. It is not
4180 used to send channel message packets anymore, as server never
4183 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4184 va_arg()s as it seems to require it nowadays. I guess, if SILC
4185 is compiled with older va_arg() the new code should work anyway.
4187 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Splitted core library. Core library (lib/silccore) includes
4190 now only SILC protocol specific core (and common) components.
4191 Created new utility library (lib/silcutil) that includes more
4192 generic purpose stuff. The stuff for util library was taken
4193 from the old core library. This was minor and easy split.
4195 * Created SILC Client Library (lib/silcclient) that includes
4196 implementation of the SILC client without user interface. This
4197 was major move from silc/ directory. The code has been changed
4198 so that it is transparent towards the user interface. The
4199 silc/ directory includes now the same user interface as before
4200 and it uses the new client library. Read lib/silcclient/README.
4201 Basicly, the client library performs everything else related
4202 to SILC except user interface handling. Also, configuration
4203 files are considered to be part of user interface and library
4204 does not handle them.
4206 This change also changed a lot of structures, function naming etc.
4207 Most important change was that SilcClientWindow object was
4208 renamed to SilcClientConnection in the client library. Created
4209 also new file lib/silcclient/ops.h. Also added new files
4210 silc/local_command.[ch] and silc/client_ops.[ch].
4212 All these changes were made to make it easier for user interface
4213 designers to create what ever user interface for the SILC client
4216 It is also expected that the server will be moved to lib
4217 directory as well and SILC Server Library will be created;
4218 sometimes in the future.
4220 * Removed Local commands from lib/silccore/silccommand.h as
4221 they are application specific and new client library does not
4222 handle any of those anymore.
4224 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4225 old client implementation in silc/.
4227 * Added support for callback functions in SILC_LOG_* macros.
4228 Application can now set its own callbacks that will be called
4229 instead of using the default functions that will always print
4230 the debug messages to stderr (or stdout). Also, debugging can
4231 now be disabled by setting silc_debug to FALSE and re-enabled by
4232 setting it to TRUE. Note, that logging will still work even
4233 if debugging is disabled.
4235 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4236 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4237 silc_log_reset_debug_callbacks.
4239 * To enable debugging in silc client one must give now -d
4240 option on command line.
4242 * Changed silc_schedule_init to automatically allocate task queues
4243 if they are not allocated before calling it.
4245 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added GMP 3.1 into math library.
4249 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4252 a channel in SILC network. The packet is used by servers and
4253 routers to notify other routers that user has left a channel.
4254 This little feature was missing until now. Added the feature
4255 to protocol specification as well.
4257 Added functions: silc_server_send_remove_channel_user and
4258 silc_server_remove_channel_user into server.[ch].
4260 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4261 lib/silccore/silcpacket.h. However, they are not implemented
4264 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Fixed joining to a channel and sending channel messages
4267 between server and router. The channel message sending should
4268 now work inside a cell.
4270 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Fixed the private message sending between server and router.
4273 The private message sending should now work inside a cell.
4275 * Added silc_server_replace_id into server.[ch] to replace
4276 existing ID in the SILC network.
4278 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4279 and silc_idlist_replace_server_id into idlist.[ch] in server.
4281 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Fixed the server to server connections. Server can again now
4284 connect to router. Router to router connections probably does
4287 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Added dynamic protocol registering support. Now protocols can
4290 registered and unregistered on the fly. Patch by cras.
4292 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * Added lib/contrib directory to hold routines that some platforms
4295 don't have but are needed by SILC.
4297 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4298 into lin/contrib to provide getopt() and getopt_long() for
4299 those who don't have it.
4301 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Added AWAY command to client. When away message is set and
4304 client receives a private message packet the client automatically
4305 replies to the sender with the away message.
4307 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4308 bug seemed to be the cause of recent problems when compiling
4311 * Added version detection support to SKE protocol specification
4312 and added the new changes to the SKE implementation as well.
4313 There were other minor changes in the SKE protocol as well.
4315 Many changes in lib/silcske/silcske.[ch] and in
4316 lib/silcske/payload.[ch].
4318 * Added ^U functionality, clear input line. Patch from cras.
4320 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Mainly small bugfixes on core library. Fixed some debugging
4323 logging and buffer overflow in silclog.c.
4325 * Updated config.sub and config.guess on the distribution tree.
4327 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Added command lagging support in server. Client may execute
4330 commands now only once in two seconds.
4332 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Optimized packet reception. MAC computation and checking is now
4335 also more optimized. A lot previously duplicated code is now
4336 used as generic by both client and server.
4338 * Fixed key pair generation in clientutil.c
4340 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Added into lib/silccore/silcbufutil.[ch] new function;
4343 silc_buffer_realloc.
4345 * Moved generic packet sending/encryption functions to
4346 lib/silccore/silcpacket.[ch] from client and server. Some
4347 rewriting of the functions.
4349 * Moved all generic packet reception/decryption functions to
4350 lib/silccore/silcpacket.[ch] from client and server. The
4351 packet processing is now much cleaner in both client and server.
4352 These were major changes in both client and server.
4354 * Created many common functions in server to do packet sending.
4355 Previously code were duplicated a lot, this has been removed
4358 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Rewrote major parts of the ID cache system. Don't know
4361 whether it is better now or not but at least the API is more
4364 * Major rewrite on ID cache stuff on client because of the ID
4365 cache API changes. Added idlist.c to client.
4367 * Also major rewrite on ID cache stuff on server as well.
4368 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4369 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4370 in hand, instead they are all put into the ID cache system now.
4371 All server_idlist_* routines uses ID cache now instead of
4372 traversing its own lists (those lists does not exist anymore).
4373 SilcIDList though still exists. Also, SilcXXXEntry's are
4376 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Finally made the SKE implementation compliant to the protocol
4379 specification. All mp integers are now binary encoded as
4380 opposed being HEX encoded.
4382 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4385 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4386 functions: silc_[encode/decode]_pem. Also added function
4387 silc_encode_pem_file to PEM encode with newlines ('\n') for
4390 * SILC public keys are now encoded either PEM or binary. Same
4391 option is for private keys as well. By default private keys
4392 are binary encoded and public keys PEM encoded. Silly HEX
4393 encoding were removed.
4395 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4396 function to create fingerprints.
4398 * Fixed a bug in SHA1; does not change the original data anymore.
4400 * Partly implemented INFO command on client and server side.
4401 Fixed CLEAR command. Changes to SERVER command; show current
4402 server(s) when giving command without arguments. Added
4403 VERSION command to client.
4405 * Added check to server that unregistered connections cannot
4406 execute commands (unless it is specificly allowed).
4408 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Fixed screen refresh.
4412 * Fixed channel joining bug from client. On some circumstances
4413 client tried to join to a channel it had already joined.
4415 * Added public key verification process into client's protocol.c.
4416 The client now verifies the public key from user and saves
4417 it into ~./silc/serverkeys/ directory.
4419 Added into: clientutil.[ch]: silc_client_verify_server_key.
4421 * Changed SKE protocol's silc_ske_initiator_finish function
4422 to accept callback function that verifies the received public
4423 key. Removed old silc_ske_verify_public_key function.
4425 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4428 silc_pkcs_private_key[_data]_set.
4430 * Made the password and public authentication more cleaner in
4431 server's protocol.c.
4433 * Removed historic and obsolete protocol `channel_auth' from
4434 both client and server.
4436 * Removed wrong way of sending command status messages from
4437 server to client in server's command.c. The old way violated
4438 protocol specification.
4440 Changes to silccore/silccommand.[ch]: removed
4441 silc_command_encode_status_payload -> not needed anymore,
4442 changed silc_command_encode_payload_va to accept extra
4443 argument on variable argument list. The argument type must
4444 now be provided to the function. Also, added new function:
4445 silc_command_encode_reply_payload_va which is same as
4446 normal command_encode_payload_va except command status type
4447 is provided as extra argument.
4449 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Added ~./silc directory handling. The directory includes the
4452 public and private keys for the client.
4454 Added silc_client_check_silc_dir, silc_client_create_identifier
4455 and silc_client_load_keys.
4457 * Implemented SILC protocol compliant public key. Added public
4458 and private key saving to and loading from files.
4460 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4461 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4462 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4463 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4464 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4466 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4467 silc_pkcs_load_[public/private]_key.
4469 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Added silc_server_get_route (route.[ch]) to get connection
4472 data for the fastest route for given ID.
4474 * Implemented INVITE command on client and server. The command
4475 were re-defined in the SILC Protocol Specification and the
4476 implementation now complies with the specification.
4478 * Implemented PING command on client and server.
4480 * Implemented NAMES command on client and server. The server side
4481 supports currently only normal server not router server yet.
4482 Some changes to NAMES definition in SILC protocol specification.
4484 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Implemented LEAVE command on client and server.
4488 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4489 again. This change was made to the protocol as well. Server
4490 should not violate the protocol specification anymore.
4492 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4495 was tested. SOCKS4 was not but should work anyway.
