3 * Do not delete the channel rekey task when adding it
4 for in silc_server_create_channel_key.
6 * Changed the silc_server_create_channel_key to return
7 TRUE or FALSE to indicate the success of the channel key
10 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
12 * Fixed MSVC++ project files and added missing files to
13 Makefiles under win32/.
15 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
17 * Do not add TCP_NODELAY flag if the operating system
18 does not have it defined. Affected files are
19 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
21 * Fixed buffer overflow from Irssi SILC Client. Affected
22 file irssi/src/fe-common/core/themes.c.
24 * Fixed double free in client library in the file
25 lib/silcclient/client.c when disconnecting from server.
27 * Applied double free patch from cras to Irssi SILC client.
28 Affected files irssi/src/core/[modules/expandos].c
30 * Fixed the disconnection handling to Irssi SILC Client.
31 The application must call silc_client_close_connection
32 in ops->connect client operation in case of failure of
33 the connection. Affected file is
34 irssi/src/silc/core/client_ops.c.
36 * Do not set sock->protocol to NULL in the function
37 silc_client_close_connection after executing the protocol's
38 final callback since the sock might not be valid anymore.
39 Affected file lib/silcclient/client.c.
41 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
43 * Do not enable SILC_THREADS if the linking with libpthread
44 did not happen. Affected file configure.in.pre.
46 * Added notion to protocol specification that server must
47 verify the sent authentication payload with CMODE when
48 setting the channel founder key. Implemented it to the
49 server. Affected file silcd/command.c.
51 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
53 * Added _EXTRA_DIST SILC distribution variable to the
54 distributions file. It is used to conditionally add extra
55 files or directories to the specific distribution. Affected
56 files ./prepare, Makefile.am.pre and distributions.
58 Removed the `_' from the start of the distribution names.

64 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
66 * Fixed a double free in disconnection in the server. Affected
67 file is silcd/server.c.
69 * Fixed the lib/silcske/groups.c to work now also with GMP
70 MP library. The string conversion did not work when using
71 specific base and the base is indicated in the string as well.
73 * Created win32/ directory which now includes MSVC++ specific
74 stuff so that toolkit (DLLs) may be compiled with MSVC++.
75 It will appear only in the toolkit distribution
77 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
79 * Changed the key material distribution function in case when
80 the hash output is too short. The data is now concatenated
81 a bit differently than it used to. Made the change to the
82 SKE protocol specification.
84 * Added better GMP detection to configure.in.pre. A patch
87 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
89 * Fixed a minor bug in SKE that might cause some problem on
90 some platforms. Affected file lib/silcske/silcske.c.
92 * Added the cookie checking for initiator in the SKE. It checks
93 that the responder returns the sent cookie unmodified. The
94 affected file is lib/silcske/silcske.c. Added new SKE
95 error type INVALID_COOKIE that can be sent during the
96 negotiation. Fixed some memory leaks as well.
98 * Added the "invalid cookie" error message to Irssi SILC client's
101 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Added `task_max' field to the SilcClientParams to indicate
104 the maximum tasks the scheduler can handle. If set to zero,
105 default values are used. Affected file lib/silcclient/silcapi.h.
107 * Fixed memory leaks in silc_client_close_connection. Affected
108 file lib/silcclient/client.c.
110 * Added silc_client_del_client_entry to client library to free
111 all memory of given client entry. Affected file is
112 lib/silcclient/idlist.[ch].
114 * Added new functions silc_client_del_channel and
115 silc_client_del_server to delete channel and server entries.
116 Affected file lib/silcclient/[silcapi.h/idlist.c].
118 * Removed silc_client_del_client_by_id from silcapi.h.
120 * Fixed the INFO command to return the server's own info
121 correctly when querying by Server ID. Affected file is
124 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
126 * Removed the non-blocking settings in WIN32 code in the
127 silc_sock_[read/write] and added SleepEx instead. Affected
128 file lib/silcutil/win32/silcwin32sockconn.c. The availability
129 of input data is now checked with FIONREAD and ioctlsocket.
131 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
133 * Call silc_schedule_task_del_by_context in the
134 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
135 Affected file lib/silccore/silcprotocol.c.
137 * Call silc_protocol_cancel for active protocols in the
138 silc_server_close_connection if the funtion
139 silc_server_free_sock_user_data has not been called.
140 Affected file silcd/server.c.
142 * Generic tasks cannot be deleted using the del_by_fd
143 task deleting function since generic tasks does not match
144 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
146 * Added a notion to SILCOPER help file that the SILCOPER works
147 only on router server, not on normal server.
149 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
151 * Added for WIN32 support for the new scheduler as well.
152 Affected file lib/silcutil/win32/silcwin32schedule.c.
154 * Fixed the SHA1 implementation to work on various platforms.
156 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
158 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
159 API. It is part of the scheduler now. Everything else is
160 as previously but some functions has changed their names.
161 Checkout the lib/silcutil/silcschedule.h for the interface.
162 Updated all applications to use the new interface. Affected
163 files are lib/silcutil/silcschedule.[ch].
165 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
167 * Found a bug in the SKE implementation. The HASH value,
168 specified by the protocol, was not computed correctly. The
169 public key of the responder was not added to the computation
170 even though it is mandatory. Affected file lib/silcske/silcske.c.
171 This unfortunately causes incompatibilities with older
174 * Added WIN32 specific network init and uninit functions:
175 silc_net_win32_init and silc_net_win32_uninit to init and uninit
176 the Winsock2. Affected file lib/silcutil/silcnet.h and
177 lib/silcutil/win32/silcwin32net.c.
179 * Set the socket always to nonblocking mode on WIN32 after
180 reading data or writing data. Affected file is
181 lib/silcutil/win32/silcwin32sockconn.c.
183 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
185 * Fixed various compilation problems under WIN32. Affected
186 files lib/silcutil/win32/silcwin32thread.c and
187 lib/silcutil/win32/silcwin32schedule.c.
189 * Removed all _internal.h #includes from public header
190 files. Internal headers must never be included from
193 Removed also the lib/silcske/payload_internal.h file.
195 * All include files that may be needed (public and some others
196 included by the public headers) by application developers are
197 now copied to the ./includes directory. It does not copy any
198 internal headers. Affected file Makefile.defines.pre and all
199 Makefile.am's under lib/ and subdirs.
201 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
203 * Do not change the ~/.silc directory's permissions automatically.
204 Affected file irssi/src/silc/core/clientutil.c.
206 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
208 * Do not cancel the protocol in silc_server_close_connection
209 it might cause recursion. Now cancelled in the function
210 silc_server_free_sock_user_data. Affected file silcd/server.c.
212 * Fixed the silc_server_remove_clients_by_server to regenerate
213 the channel keys correctly finally. Added also new function
214 silc_server_remove_clients_channels to actually do it.
215 Affected file silcd/server.c.
217 * Fixed the silc_server_new_channel to not crash by giving
218 wrong router to the new channel. Affected file is
219 silcd/packet_receive.c.
221 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
223 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
224 which is given as argument to the silc_client_alloc now.
225 It can be used to configure the client and set various parameters
226 that affect the function of the client.
228 * The USERS command in server did not check whether the channel
229 is private or secret. Affected file silcd/command.c.
231 * Added new argument to the USERS command in protocol specification.
232 The USERS command now can take the channel name as argument
233 as well. Added support for this in client and server and
234 updated the protocol specs.
236 * Completed the GETKEY command in client. It can be now used
237 to fetch also servers public key not only some clients.
238 Affected files lib/silcclient/command[_reply].c.
240 * Added silc_client_get_server to return server entry by the
241 server name. Affected files lib/silcclient/silcapi.h and
244 * Redefined the IDENTIFY command in protocol specification to be
245 more generic. It now can be used to query information about
246 any entity in the SILC Network, including clients, servers and
247 channels. The query may be based either the entity's name
248 or the ID. Added support for this in both client and server.
250 Affected files silcd/command.c and lib/silcclient/command.c
253 * Optimized the WHOIS and WHOWAS commands in the server. Removed
254 the _from_client and _from_server functions. Affected file
257 * Added silc_client_get_channel_by_id_resolve to the file
258 lib/silcclient/silcapi.h to resolve channel information by
259 its ID. Added also silc_client_get_channel_by_id that
260 does not resolve it from the server.
262 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
264 * Added SilcServerEntry context into the client library
265 to represent one server. The INFO command now allocates
266 these to save the resolved server info. For now on the
267 client library will also keep information about servers,
268 connected and resolved with INFO.
270 The INFO command now allocates the SilcServerEntry context
271 and saves the server info there. The COMMAND_REPLY in
272 the INFO now returns the parameters to application in
273 same order as defined in the protocol specification.
275 The entries are cached in the client->server_cache.
277 * The INFO command is now issued after received the Client ID
278 from the server. Affected file lib/silcclient/client.c.
280 * The CMODE_CHANGE notify may now return also an SilcServerEntry
281 to the application as the mode changer might be server.
282 It is guaranteed that NULL is not returned anymore to the
283 application. Affected file lib/silcclient/client_notify.c.
285 The ID Type is now also passed to the application so that
286 it can check whether the returned entry is SilcClientEntry
289 Added new function silc_client_get_server_by_id to return
290 the server entry by ID. Affected files are the
291 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
293 * Do not create the channel in the Irssi SILC Client when issuing
294 the JOIN command but when received the sucessful JOIN command
295 reply. Otherwise the channel might get created even though we
296 could not join it. The Affected file is
297 irssi/src/silc/core/[silc-channels.c/client_ops.c].
299 * Fixed a channel joining bug in router. The router must also
300 check the channel modes, invite and ban lists etc. when serving
301 the JOIN command sent by normal server. Affected file is
302 silcd/command.c. The router now resolves the client's
303 information from the server who sent the JOIN command if it
304 does not know it, and processes the JOIN command only after
307 * Changed the SilcCommandCb to take new argument; void *context2.
308 Affected file lib/silccore/silccommand.h
310 The second argument in the command callbacks in the server now
311 includes the SilcServerCommandReplyContext if the command was
312 called as pending command callback from the command reply.
313 Otherwise it is NULL. When called as pending the status of the
314 command reply will be checked and if it was erronous the
315 error will be sent to the original sender of the command.
316 This way the client always receives the error messages even
317 though the server was actually the one who received the error
318 when it resent the command to router, for example. Affected
319 files silcd/command[_reply].[ch].
321 * Fixed sending WHOWAS command's error message to client if
322 the requested client could not be found. It was missing.
325 * Changed the CMODE and CUMODE commands reply arguments in the
326 protocol specification. The Channel ID is now sent in both
327 of the commands to identify the channel. Implemented this
328 new feature to the client and server. Affected files
329 lib/silcclient/command_reply.c and silcd/command.c.
331 * Made better checks for invite and ban lists in the JOIN
332 command in server. Affected file silcd/command.c.
334 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
336 * The server now performs the incoming host IP/DNS lookup
337 using the silc_socket_host_lookup and thus does not block
338 the server anymore. Affected file silcd/server.c.
340 * Completed the multi-thread support for SILC Scheduler in
341 the lib/silcutil/silcschedule.c.
343 * Fixed the configure.in.pre to detect the pthread correctly
346 * Fixed a deadlock in silc_task_queue_wakeup in the file
347 lib/silcutil/silctask.c.
349 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
351 * Added new function silc_schedule_wakeup that is used in
352 multi-threaded environment to wakeup the main thread's
353 schduler. It needs to be used when a thread adds a new task
354 or removes a task from task queues. After waking up, the
355 scheduler will detect the task queue changes. If threads
356 support is not compiled in this function has no effect.
357 Implemented the wakeup mechanism to both Unix and WIN32
358 systems. Affected files are lib/silcutil/silcschedule.[ch],
359 lib/silcutil/unix/silcunixschedule.c and the
360 lib/silcutil/win32/silcwin32schedule.c.
362 * Added new function silc_task_queue_wakeup to wakeup the
363 scheduler by the specified task queue. Affected file
364 lib/silcutil/silctask.[ch].
366 * The silc_socket_host_lookup_start now wakes up the scheduler
367 after adding the timeout task. Affected file is
368 lib/silcutil/silcsockconn.c.
370 * The silc_socket_host_lookup is synchronous now if the threads
371 support is not compiled in. However, the callback is still
372 called asyncronously through the scheduler, anyway. Affected
373 file lib/silcutil/silcsockconn.c.
375 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
377 * Added new function silc_socket_host_lookup to perform
378 asynchronous IP and FQDN lookups for the socket connection.
379 Affected files lib/silcutil/silcsockconn.[ch].
381 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
383 * Added SILC_MUTEX_DEFINE to define the mutex on environments
384 that may or may not compile the mutex support in.
386 Changed the silc_mutex_alloc interface. It allocates the
387 mutex now to the sent pointer and returns TRUE or FALSE.
389 Affected file lib/silcutil/silcmutex.h.
391 * Wrote the SILC Task Queue interface to support multi-threads.
392 Affected file lib/silcutil/silctask.[ch].
394 * Wrote the SILC Scheduler to support multi-threads. Affected
395 file lib/silcutil/silcschedule.c.
397 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
399 * Implemented the SILC Mutex API and SILC Thread API for WIN32
400 in lib/silcutil/win32/.
402 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
404 * Defined SILC Mutex API and SILC Thread API and implemented
405 them for Unix. Affected files are
406 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
407 lib/silcutil/unix/silcunixmutex.c and
408 lib/silcutil/unix/silcunixthread.c.
410 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
412 * Fixed the silc_server_remove_clients_by_server's channel
413 key re-generation. The hash table handling was incorrect
414 and would not work with many channels. Affected file is
417 * Fixed some memory leaks around the server code.
419 * Rewrote the silc_server_get_users_on_channel to support IPv6
420 based Client ID's. Affected file silcd/server.c.
422 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
423 specification. However, a separate document must be written
424 to define the detailed signing procedure and the payload
425 associated with the flag. Defined the flag to the
426 lib/silccore/silcchannel.h as well.
428 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
430 * Changed the dynamic tables to static size tables in the
431 lib/silccrypt/silchmac.c.
433 * Removed GCC dependencies from the code. A patch by cras.
435 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
437 * Do not show the error "Error receiving packet bla bla"
438 in server if it really was not an error (-2 means that reading
439 is pending). Affected file silcd/server.c.
441 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
443 * Fixed a possible crash in silc_server_remove_clients_by_server
444 in silcd/server.c. Fixed there also some memory leaks.
446 * Fixed the silc_idlist_replace_client_id. It could replace
447 wrong key in the hash table. Affected file silcd/idlist.c.
449 * Do not check whether there are global users on the channel
450 if the channel->global_users is FALSE. Affected functions
451 silc_server_remove_from_one_channel and
452 silc_server_remove_from_channels in silcd/server.c. Also,
453 do not check if the removed client is local as we can be
454 sure that global client was not removed from the channel
455 and checking for global users is not needed.
457 * The silc_server_remove_clients_by_server now re-generates
458 the channel keys correctly for those channels that had
459 clients removed from them. Affected file silcd/server.c.
461 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
463 * Found the reason of random crashes in the server. We weren't
464 ignoring the SIGPIPE signal (which can be sent in write())
465 and it crashed the server. Affected file silcd/silcd.c.
467 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
469 * Assure that sock->user_data is not NULL in the function
470 silc_server_packet_send in silcd/packet_send.c.
472 * Disconnect the remote connection if it could not be added
473 to any ID lists in the server. The affected file is
476 * Check in silc_server_packet_send[_real/dest] that the
477 socket is not disconnecting and ignore the data if it is.
478 Affected file silcd/packet_send.c.
480 * Define inline to __inline on native WIN32 compilation.
481 Affected file includes/silcwin32.h.
483 * Added some explicit type casts for inline code since MSVC
484 require them. Affected files lib/silcutil/silcbuffer.h,
485 lib/trq/silcdlist.h and lib/trq/silclist.h.
487 * Print warning in log files from now on if the packet
488 decryption fails. Affected file silcd/server.c.
490 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
492 * Changed the `say' client operation's interface to accept
493 new `type' argument to indicate the type of the message sent
494 by the library. The application may filter the library's
495 messages according the type. The affected file is the
496 lib/silcclient/silcapi.h.
498 * Added two new functions to lib/silcclient/silcapi.h:
499 silc_client_del_client and silc_client_del_client_by_id.
500 Affected file lib/silcclient/idlist.c.
502 * Moved the clientincludes.h from includes/ to silc/ and
503 serverincludes.h from includes/ to silcd/.
505 * The modes for the CMODE and CUMODE are now passed as
506 uint32 for application with COMMAND_REPLY. The affected
507 file is lib/silcclient/command_reply.c.
509 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
511 * /WHOIS without arguments shows client's own information.
512 Affected file lib/silcclient/command.c.
514 * Changed PING to not accept any arguments. The specs
515 says that client can ping only the connected server so
516 requiring an argument is not needed. Affected file is
517 lib/silcclient/command.c.
519 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
521 * Fixed a fatal bug in private message sending and reception
522 encryption and decryption when using private message keys.
523 The implementation was incorrect and did not follow the
524 specification. It causd that some of the message were
525 lost since it did not use the sending and receiving keys
526 as the protocol suggests. This has been fixed and will cause
527 incompatibilities with older clients when sending private
528 message encrypted with private message keys. Affected files
529 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
530 and various other in Irssi SILC Client.
532 Added `responder' boolean argument to the functions
533 silc_client_add_private_message_key[_ske] to indicate when
534 the key is added as responder or initiator of the key
537 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
539 * Removed the silc_ske_check_version function and created
540 a SilcSKECheckVersion callback. Added also a function
541 silc_ske_set_callbacks that is now used to set all SKE
542 callbacks. The callback functions are not given to
543 the SKE functions anymore, but this function is used to
546 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
548 * Added `silc_version' argument to the silc_client_alloc
549 to define the version of the application for the library.
550 The library will use the version string to compare it
551 against the remote host's (usually a server) version
552 string. Affected file lib/silcclient/silcapi.h
554 * Added the KE protocol context to Key Agreement context
555 in client library so that we can abort the SKE if it
556 is in process when we get timeout. Affected file is
557 lib/silcclient/client_keyagr.c.
559 * Do not resolve the client ID forever if it returns in the
560 first time that such client does not exist. This was done
561 for example with private message. Affected file is
562 lib/silcclient/client_prvmsg.c.
564 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Do not add regex.h for WIN32. The affected file
567 includes/silcincludes.h.
569 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
570 not work yet 100%. It generates the DLL's automatically
571 when compiling with --with-win32 under cygwin.
573 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
575 * lib/contrib/regex.c is not compiled on WIN32.
577 * Added silc_net_get_socket_opt function to the
578 lib/silcutil/silcnet.h.
580 * Added includes/silcwin32.h for WIN32 specific includes
583 * Do not use ptime structure or any of the posix process
584 functions on WIN32 in lib/silccrypt/silrng.c.
586 * Added silc_gettimeofday to provide generic function
587 for struct timeval on all platforms. Added the function
588 to lib/silcutil/silcutil.h.
590 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
592 * Moved the lib/silccore/silcsockconn.[ch] to the utility
593 library as they clearly belong there. As a plus side we
594 can make the actual socket connection routines platform
597 Added also new generic function silc_socket_read and
598 silc_socket_write (that used to be silc_packet_[read/write].
599 The implementation of these are platform specific.
601 * Added WIN32 specific routines of silc_socket_[read/write]
602 to lib/silcutil/win32/silcwin32sockconn.c.
604 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Added preliminary support for native WIN32 compilation under
607 cygwin (using the -mno-cygwin option for GCC) to the
608 ./configure.in.pre. The --with-win32 now prepares the
609 compilation for native WIN32.
611 * Rewrote the SILC Scheduler interface in the file
612 lib/silcutil/silcschedule.h. The scheduler is now context
613 based and does not have anymore any global static scheduler.
614 Moved the Unix scheduler to the lib/silcutil/unix/ directory
615 and created lib/silcutil/win32 directory for WIN32 based
618 * Added Unix specific network routines to the
619 lib/silcutil/unix/silcunixnet.c and the old
620 lib/silcutil/silcnet.c includes now only generic routines.
622 Added WIN32 specific network routines to the
623 lib/silcutil/win32/silcwin32net.c.
625 * Added Unix specific utility functions from the
626 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
628 * Added WIN32 SILC Scheduler to the file
629 lib/silcutil/win32/silcwin32schedule.c. The code is of course
632 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Do not handle JOIN notify in the server if the target client
635 is not registered (idata->registered == FALSE). The affected
636 file is silcd/packet_receive.c.
638 * Update the nickrec->founder in event_cumode in the Irssi SILC
639 client. Affected file irssi/src/silc/core/silc-channels.c.
641 * Fixed the CUMODE_CHANGE notify handling in the server when
642 server and router are announcing their clients on channels.
643 Now the mode changes are saved and notified correctly. The
644 affected file is /silcd/packet_receive.c.
646 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
647 They really did not replace the cache entry in the ID Cache.
648 Now they do that. Affected file silcd/idlist.c.
650 * Fixed the KICK notify handling in the Irssi SILC client to
651 update the channel records so that the kicked client does not
652 appear to be on the channel. The affected file is
653 irssi/src/silc/core/silc-channels.c.
655 * Always update the conn->current_channel when executing command
656 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
658 * Fixed the KILL notify handling in Irssi SILC client to remove
659 the killed client on all channels.
661 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Fixed the silc_parse_command_line to remove extra spaces
664 from the start and end of the arguments. Affected file is
665 lib/silcutil/silcutil.c.
667 * Cancel and free any active protocol in the function
668 silc_server_close_connection. Affected file silcd/server.c.
670 * Cancel and free any active protocol in the function
671 silc_client_close_connction. Affected file is
672 lib/silcclient/client.c.
674 * Do not execute the KILL command for clients that are in
675 history (ie. they are not in the network). Affected file is
678 * Fixed KILL notify handling, client does not crash anymore.
679 Affected file irssi/src/silc/core/silc-channels.c.
681 * Reduced the default packet buffer size from 2048 to 1024 in
682 lib/silccore/silcpacket.c.
684 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
685 counter to the SKE context that is incresed when the SKE library
686 performs async operation outside the library. If the outside
687 process frees the SKE context and FREED status will be set
688 and the library will detect after the sync operation that the
689 libary is freed. The affected files are
690 lib/silcske/silcske[_status].[ch].
692 * Resolve the client entry information in the function
693 silc_client_channel_message to assure that NULL pointer is not
694 passed as client entry to the application. */
696 * Fixed the task timeout calculation to assure that there is
697 never negative timeouts. The affected file is
698 lib/silcutil/silcschedule.c.
700 * Fixed the channel user mode notification sending in server.
701 It was sent point-to-point to the router (or to server by router)
702 but it needs to be destined to a channel. The routines now
703 supports sending the channel user mode notifys to the channels
704 when announcing clients and channels. Affected files are
705 silcd/server.c and silcd/packet_receive.c.
707 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
708 It did not actually replace the old channel entry in the cache.
709 Affected file lib/silcclient/client_notify.c.
711 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Fixed a possible crash in silc_packet_send_prepare. It now
714 assures always that there is enough space in the buffer and
715 at the tail area of the buffer (for MAC).
717 Fixed the inbound buffer reallocation in silc_packet_read.
718 It was old code and did not handle the reallocation correctly.
721 The affected file is lib/silccore/silcpacket.c.
723 * Fixed buffer overflow in silc_parse_nickname in the file
724 lib/silcutil/silcutil.c.
726 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
728 * make install generates new server keys only if there is not
731 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
733 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
734 Added check that if the NOREPLY is set then we will not send
735 the away message. This avoids infinite loop of away messages
736 if both clients are away. The affected file is
737 lib/silcclient/client_prvmsg.c.
739 * Fixed client crash if /NICK was given without arguments.
740 Affected file lib/silcclient/command.c.
742 * Server does not send the invite list in INVITE command back
743 to the client if the list was not altered. Added this notion
744 to the protocol spec as well. Affected file silcd/command.c.
746 Fixed possible crash in INVITE command by checking the
747 value of silc_server_get_client_route command.
749 * Fixed the INVITE notify type handling. The arguments are now
750 taken in correct order and client does not crash. The affected
751 file is irssi/src/silc/core/silc-channels.c.
753 Removed the "Inviting xxx to channel" message from the
754 client library away and let the application handle it.
755 Affected file lib/silcclient/command.c. Added that message
756 to Irssi SILC client's message formats.
758 * Fixed CMODE command crash in client. It now checks the
759 amount of arguments correctly and does not crash. The affected
760 file is lib/silcclient/command.c.
762 * Do not create new channel automatically in silc_channels_join
763 but check whether the channel by that name already exists.
764 Affected file irssi/silc/core/silc-channels.c.
766 * Do not send the SERVER_SIGNOFF to router if the disconnected
767 entity was the router. Affected file silcd/server.c.
769 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
770 SILC client as it was missing from there.
772 Added the handling of the KICK notify to the Irssi SILC client
773 as it was missing. Added "you have been kicked" message to
774 Irssi SILC client's message modules formats.
776 Added the handing of the KILL notify to the Irssi SILC client
777 as it was missing. Added the kill message module formats
780 The affected file is irssi/src/silc/core/silc-channels.c.
782 * The router did not save the channel mode the server announced.
783 Affected file silcd/packet_receive.c.
785 * Fixed a possible crash in INFO command in server. If the
786 server did not provide the server info it crashed. Affected
787 file silcd/command.c.
789 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
791 * Fixed the GETKEY command in the server to check also the
792 global list. Otherwise the GETKEY would not work correctly
793 in normal SILC server. Affected file silcd/command.c.
795 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Fixed GETKEY crash, it crashed if the command did not succseed.
799 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
802 is now real and not just an macro interface to GMP.
804 Removed the entire GMP from the source tree and imported new
805 NSS MPI library instead. Reason for removing GMP is that it is
806 extremely large and compiles extremely slow. The NSS MPI
807 is only a few files and compiles in less than 10 seconds.
808 The speed is also about the same as GMP. The MPI is imported
811 If the system has GMP installed we will still use the GMP.
812 If it is not then the NSS MPI will be compiled.
814 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
816 * Merged a long nickname (127 characters long) crash bugfix from
817 Irssi CVS tree. Affected file irssi/src/core/misc.c.
819 * Merged a freed memory reference bugfix from Irssi CVS tree.
820 Affected file irssi/src/core/commands.c.
822 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
824 * Added the server's public key sving and verification to the
825 server when performing the SKE. This was missing and the
826 remote server's (or router's) public key was accepted without
827 checking whether we have it previously or trust it at all.
828 Affected file silcd/protocol.c.
830 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Check in the silc_server_timeout_remote if protocol is active
833 and make sure that the protocol's final callback is called so
834 that all memory if freed. Affected file silcd/server.c.
836 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
838 * silc_server_whois_send_reply crashed the server if the nickname
839 was 127 characters long. Affected file silcd/command.c.
841 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Added sanity check to the silc_server_new_client. If the hostname
844 is provided inside username then check that the provided hostname
845 really is the same as the resolved one. If the hostname was not
846 resolved then check it from the public key. Affected file is
847 silcd/packet_receive.c.
849 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
850 if the server disconnected us and the connection is not valid
851 anymore. Affected file irssi/src/silc/core/silc-channels.c.
853 * Moved the silc_client_[chmode|chumode|chumode_char] away from
854 the library to the lib/silcutil/silcutil.[ch].
856 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
858 * Close log file after open. Affected file
859 lib/silcutil/silclog.c.
861 * Check whether sock == NULL in silc_client_send_packet and return
862 if it is. Affected file lib/silcclient/silcclient.c.
864 * Check rec->entry == NULL in the Irssi SILC Client before
865 sending the channel message. Affecte file is
866 irssi/src/silc/core/silc-servers.c.
868 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Merged a splitted window bugfix from Irssi CVS tree. The
871 affected file is irssi/src/fe-text/textbuffer-view.c.
873 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
874 It did not print nickname.
876 * Improved the distributions system a bit.
878 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
881 irssi/src/fe-text/gui-window.c.
883 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
884 to in-active server. The affected file is
885 irssi/src/silc/core/client_ops.c.
887 * Resolve the client in USERS command reply if the entry does
888 not have username resolved. The affected file is
889 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
890 command to WHOIS command to really resolve stuff. The USERS
891 is not used any more in any critical section so WHOIS can
892 be used even though it might be slower than IDENTIFY.
894 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
897 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Changed the protocol API a bit more consistent in the
900 lib/silccore/silcprotocol.[ch].
902 * Changed the following headers to ROBODoc format:
904 lib/silccore/silcpayload.h
905 lib/silccore/silcprotocol.h
906 lib/silccore/silcsockconn.h
908 All core library headers are now formatted.
910 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Fixed a bug in Irssi SILC client; do not show that you are
913 server/router operator if you really are not. Affected file is
914 irssi/src/silc/core/client_ops.c.
916 * Renamed silc_command_free_payload to silc_command_payload_free.
917 Affected file lib/silccore/silccommand.h
919 * Added silcmath.h to include the prototoypes of various routines
920 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
923 * Changed the following headers to ROBODoc format:
925 lib/silccore/silcchannel.h
926 lib/silccore/silccommand.h
927 lib/silccore/silcid.h
928 lib/silccore/silcidcache.h
929 lib/silccore/silcmode.h
930 lib/silccore/silcnotify.h
931 lib/silccore/silcpacket.h
932 lib/silcmath/silcmath.h
934 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
936 * Added checking to the server code not to start the server if
937 ciphers and stuff are not configured properly. Affected files
938 silcd/serverconfig.[h] and silcd/server.c.
940 * Changed the layout of the header files of the public interfaces
941 in the SILC libraries. The new layout supports ROBODoc
942 documentation tool (and some others) so that it is easy to create
943 a library reference manual. All the other headers and source
944 code must still follow the CodingStyle document. Also source
945 code must not include these ROBODoc stuffs, only the headers.
946 Furthermore, all public interface headers must now be named
947 by using `silc' prefix, example: silcapi.h, silccipher.h.
948 Some files were renamed due to this. All the other headers
949 must not be used as public interfaces. I will update the
950 CodingStyle document later. Changed following headers, so far:
952 lib/silcclient/silcapi.h
953 lib/silccore/silcauth.h
954 lib/silccore/silcprivate.h
955 lib/silccrypt/silcdh.h
957 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * Removed silc_client_packet_send_flush from the client library
962 as it is not needed. Affected file lib/silcclient/client.[ch].
964 * Added printing of message of unresolved authentication method
965 to the Irssi SILC client. Added it to the module formats.
966 Removed the same message from the client library.
968 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
970 * Added new distribution feature, DISTLABEL. Every distribution
971 can define own preprocessor label that can be used in the
972 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
973 file distributions, acconfig.h.pre and prepare.
975 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * Added Makefile.defines_int to include the actual definitions
978 for Makefile.defines.in. Tested the new distribution system,
979 created distributions and tested installation.
981 * Added AWAY message printing to the Irssi SILC client. Added
982 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
984 * Added SCONNECT command to call the SILC's CONNECT command.
985 Cannot use CONNECT directly since Irssi uses that internally.
986 Affected file irssi/src/silc/core/silc-servers.c.
988 Added ACTION local command. It is same as ME command but takes
989 the channel as mandatory argument.
991 Rewrote some of the Irssi's help files to suite for SILC
994 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
996 * Added Makefile.defines[.in] that should for now on be included
997 in all Makefile.am file in the source tree. That file includes
998 all common compilation definitions for SILC source tree.
1000 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Minor changes to the ./prepare script to change the package
1003 name according the distribution name to the configure.in.
1005 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Created new distribution system. Added file `distributions'
1008 that defines all the distributions that can be created out of
1009 the SILC source tree. The ./prepare script now reads that
1010 file to determine how to prepare the distributions. The
1011 first argument to the ./prepare is the name of the distribution
1012 and second is the version of the distribution. If given
1013 without arguments it creates the default (toolkit) distribution
1014 with the default version (defined in ./prepare).
1016 All Makefile.am files that are subject to the distributions
1017 are now named as Makefile.am.pre. These are ./Makefile.am
1018 and lib/Makefile.am. Others may be changed later.
1020 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Added invite list, ban list, some key management and connection
1023 error message printing to module formats in the Irssi SILC client.
1025 * Added new silc_client_set_away_message to set the away message
1026 that is back to the person who sent private message. The
1027 affected file lib/silcclient/silcapi.h and the
1028 lib/silcclient/client_prvmsg.c.
1030 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Fixed the private message sending in the Irssi SILC client,
1033 added local command KEY to the Irssi SILC client.
1035 Added key management and key agreement message formats to the
1036 irssi/src/fe-common/silc/module-formats.[ch].
1038 Added USERS (alias WHO) printing, server/router operator
1039 indication and LIST command printing to the module formats.
1041 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1043 * Fixed channel joining notify handling, cumode notify handling
1044 from Irssi SILC client.
1046 * Added SILC specific module-formats to the Irssi SILC client so
1047 that SILC specific message hilighting, colors etc is possible.
1048 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1050 Added channel mode, channel user mode, actions, notices,
1051 whois and whowas printing to the the module-formats.c.
1053 * Fixed a bug in channel deletion in the server. The channel
1054 is not left to the cache even if the channel founder auth mode
1055 is set when there are no users anymore on the channel. Affected
1056 file silcd/server.c.
1058 * The silc_net_localhost now resolves the entire hostname including
1059 the domain name. Affected file lib/silcutil/silcnet.c.
1061 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Changed the ask_passphrase client operation to be ascynchronous.
1064 It has now a completion callback and a context that the
1065 application must call after it has got the passphrase from
1066 the user. Affected files lib/silcclient/silcapi.h,
1067 lib/silcclient/protocol.c, lib/silcclient/command.c and
1070 Added SilcAskPassphrase callback that the application calls
1071 to deliver the passphrase to the library.
1073 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1074 The public key verification and especially a certificate
1075 verification is asynchronous procedure.
1077 Added new SILC_SKE_STATUS_PENDING status to indicate the
1078 request is pending and a callback will be called to finalize
1081 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1082 indicate that remote end did not send its public key (or
1083 certificate), even though we require it. Added check for this
1084 condition in the SKE. This was a security bug, now fixed.
1086 Defined new SilcSKEVerifyCbCompletion callback that is called
1087 when the verification process is completed.
1089 The affected files lib/silcske/silcske_status.h and
1090 lib/silcske/silcske.[ch].
1092 * Changed the verify_public_key client operation to be async
1093 as well. Defined SilcVerifyPublicKey callback that is used to
1094 indicate the success of the public key verification process.
1096 Changed the server and client to use the new async client
1099 * Changed the Irssi SILC client's internal scheduler to be called
1100 twice as many times as it used to be. As a result the client
1101 should be a bit faster now. Affected file is
1102 irssi/src/silc/core/silc-core.c.
1104 * Added support to Irssi SILC client of asynchronous public key
1105 verification and passphrase inquiry. Affected file is
1106 irssi/src/silc/core/silc-core.c.
1108 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1110 * Do not say "You have left channel %s" in client library.
1111 Moved it to the application. Affected files are
1112 lib/silcclient/command.c and silc/client_ops.c.
1114 * Fixed silc_client_get_clients. Command context was not
1115 duplicated and was freed memory in the callback. Affected
1116 file lib/silcclient/idlist.c.
1118 * Do not say "you are now talking..." on JOIN command in the
1119 client library. The appliation must handle it.
1121 * Do not say ".. changed topic to" in command reply in the
1122 client libary. The application must handle it.
1124 * Fixed TOPIC command sending in the client library.
1126 * Fixed a memory leak in silc_client_command_free in the file
1127 lib/silcclient/command.c.
1129 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Imported a modified version of Irssi client to the source tree.
1132 The Irssi will be used to create a new client called
1133 Irssi SILC. Imported to irssi/.
1135 Added silc_core_init_finish function to the Irssi. Affected
1136 file irssi/configure.in.
1138 A lot changes in the Makefile.ams around the irssi tree.
1140 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Do not rehash if the new size is same as the old size of the
1143 hash table, in the silc_hash_table_rehash*. The affected file
1144 lib/silcutil/silchashtable.c.
1146 * Replaced hash_table_del_by_context calls from the server
1147 (when channel->user_list and client->channels) to the
1148 hash_table_del as it is sufficient and faster.
1150 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1152 * Added silc_hash_table_list, silc_hash_table_get and the
1153 SilcHashTableList structure to provide an alternative way to
1154 traverse the hash table. The affected files are
1155 lib/silcutil/silchashtable.[ch].
1157 * Changed the server's idlist routines to use the hash table
1158 routines to optimize the code.
1160 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Replaced the client entry's `channel' list and channel entry's
1163 `user_list' list to hash tables for optimized lookup. Changed
1164 the code to use the hash table interface around the code.
1165 Affected file lib/silcd/idlist.[ch].
1167 * Added `auto_rehash' boolean argument to the function
1168 silc_hash_table_alloc to indicate whether the hash table should
1169 auto-rehash when it thinks is appropriate time. It will
1170 increase the hash table size if the there is twice as much
1171 entries in the table than the size of the table, and will
1172 decrease the size if there are twice as less entries than
1173 the size of the table.
1175 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1177 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1179 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * silc_idcache_purge_by_context deletes the entry now by context
1182 as it is supposed to do. Affected file lib/silccore/idcache.c.
1184 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1185 client is not anymore valid (WHOWAS givens the info) and not
1186 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1188 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Removed the `data' and `data_len' arguments from the ID Cache
1191 interfaces and added `name' argument. ID Cache does not handle
1192 anymore the binary data only a names associated with given ID.
1194 * When hashing a Client ID with silc_hash_id the entire ID is
1195 not hashed anymore, instead only the hash of the Client ID is
1196 hashed. This way we can access the Client ID from the cache
1197 with Client ID but with the hash of the ID (which is a hash of
1198 the nickname) as well without any difference in performance.
1200 Added also silc_idcache_find_by_id_one_ext to do one on one
1201 searching when we have the actual ID. Added also function
1202 silc_hash_client_id_compare. The affected files are
1203 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1205 * When hashing the name associated with a ID it is always done
1206 in lowercase. This way we can access the cache without worrying
1207 about case-sensitivity, even though, for example nicknames are
1210 * Fixed a bug in server with channel message sending. It put
1211 wrong ID type as destination ID. The affected file
1212 silcd/packet_send.c.
1214 * silc_idcache_del_by_context now deletes from all hash tables
1215 by context. Affected file lib/silccore/idcache.c.
1217 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Changed the client library to use the new ID Cache interface.
1220 Changes around the source tree.
1222 * Added silc_hash_table_rehash_ext to rehash with specific
1223 hash function. Affected file lib/silcutil/silchashtable.[ch].
1225 * Added silc_hash_string_compare to compare two strings in the
1226 hash table. Affected file lib/silcutil/silcutil.[ch].
1228 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Added new function silc_idcache_del_by_context into the
1231 lib/silccore/idcache.[ch].
1233 * Changed the server's ID list routines to use the new ID Cache
1234 interface. Changes around the source tree.
1236 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Added silc_hash_table_del[_by_context]_ext functions in to the
1239 lib/silcutil/silchashtable.[ch].
1241 Removed silc_hash_table_find_all* routines and added new
1242 silc_hash_table_find_foreach to replace them.
1244 Added silc_hash_table_replace_ext function as extended
1245 replacing function. Separated the simple hash table interface
1246 from the extended hash table interface in the file
1247 lib/silcutil/silchashtable.h.
1249 * Fixed minor bugs and changed it to use some of the new
1250 hash table functions in lib/silccore/idcache.c
1252 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Added new function silc_hash_table_find_all to return all keys
1255 in the hash table by the specified key. As the hash table is
1256 collision resistant it also makes it possible to have several
1257 duplicate keys in the hash table. This function may be used to
1258 find all of the keys from the hash.
1260 Added user_context arguments to the SilcHashFunction,
1261 SilcHashCompare and SilcHashDestructor to deliver user specified
1264 Added new fuctions silc_hash_table_find[_all]_ext to do
1265 extended lookup with specified hash and compare functions and
1266 specified user contexts.
1268 Added new function silc_hash_table_add_ext to add the key
1269 with specified hash function and user context.
1271 Added new function silc_hash_table_foreach to traverse all
1272 entrys in the hash table. Added SilcHashForeach callback
1275 Added new function silc_hash_table_del_by_context to delete
1276 the entry only if the context associated with the key matches.
1278 Affected files are lib/silcutil/silchashtable.[ch].
1280 * Removed silc_hash_[server/client/channel]_id and added just
1281 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1282 silc_hash_id_compare to compare two ID's using as the hash table
1283 comparison function. Added also silc_hash_data to hash
1284 binary data and silc_hash_data_compare to compare it.
1286 * Removed silc_idlist_find_client_by_hash as it is not needed
1287 anymore. Affected file silcd/idlist.[ch].
1289 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1290 to use internally the SilcHashTable. The new ID Cache is a lot
1291 faster than the old one. Some of the ID Cache interface was also
1292 rewritten and obsolete and stupid functions were removed.
1294 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Added entry_count field to the SilcHashTable to keep the number
1297 of the entries in the table. Implemented the function
1298 silc_hash_table_rehash. Added new function
1299 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1301 Fixed a minor bug in silc_hash_table_free.
1303 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1304 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1305 into the lib/silcutil/silcutil.[ch].
1307 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Implemented a collision resistant hash table into the
1310 lib/silcutil/silchashtable[ch]. See the header and the source
1311 for the SilcHashTable API.
1313 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Merged dotconf version 1.0.2 into lib/dotconf.
1317 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Do not compile anything in lib/silcsim/* if the SIM support
1320 is not enabled. The tree should now compile without problems
1323 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1325 * Compiled the SILC under cygwin. Compiled and tested briefly
1326 without problems. More tests needed. The SIMs didn't compile
1329 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1331 * Fixed possible crash in silc_get_username in the
1332 lib/silcutil/silcutil.c.
1334 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Fixed a va_arg in silc/client_ops.c.
1338 * Oops, RC5 routines were named AES and caused some problems
1339 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1341 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1343 * Added new SilcIDIP structure into the lib/silccore/id.h and
1344 replaced the old `ip' fields from all SILC ID's to that type.
1345 This is a step towards IPv6 support.
1347 The silc_id_get_len takes now the ID as an extra argument.
1348 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1349 both IPv4 and IPv6 based ID's.
1351 The affected files are lib/silccore/id.[ch] and other files
1352 around the tree using these routines.
1354 * Removed the ID length arguments in server from various
1355 silc_server_send_notify_* routines -> they are not needed
1358 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1360 * Fixed memory leak in silc_encode_pem_file in the file
1361 lib/silcutil/silcutil.c.
1363 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * Check minor version as well in the SKE. Affected files are
1366 silcd/protocol.c and lib/silcclient/protocol.c.
1368 * Added --identifier option to the server so that an identifier
1369 can be when creating the public key for the server. Affected
1370 file is silcd/silcd.c.
1372 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1373 lib/silccrypt/silcpkcs.c.
1375 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Register default ciphers and stuff when using -C option with
1378 the server. Affected file sildc/silcd.c.
1380 * Put back the servers public key filename format, it is better
1381 than the new one. For now, the client keys are saved with the
1382 new filename format. The affected file silc/client_ops.c.
1384 * Implemented the Cipher API for the rest of the ciphers that
1385 did not implement it or implemented it the wrong way.
1387 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Register default ciphers and stuff when using the -S option
1390 in the client. Affected file silc/silc.c. Same also when
1391 creating new key pair with -C option.
1393 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Fixed the silc_verify_public_key client operation function to
1396 save the public keys differently. The fingerprint is now
1397 used as filename and not the hostname. This way also the
1398 client keys are saved uniquely and not with hostnames. The
1399 affected file is silc/client_ops.c.
1401 * Trimmed the silc_hash_fingerprint function to remove extra
1402 whitespaces from the end of the fingerprint. The affected
1403 file is lib/silccrypt/silchash.c.
1407 * Added silc_cipher_register_default function to register all
1408 default ciphers. It can be used when configuration files
1409 does not exist and the application does not want any specific
1410 ciphers in any specific order.
1412 The SilcDList is now used as silc_cipher_list dynamically
1413 allocated cipher list. Removed the static list all together
1414 and now all ciphers must be allocated to the dynamic list.
1415 The silc_cipher_alloc routine was changed to check only the
1418 All silc_cipher_* routines that used to return int returns
1421 The affected files lib/silccrypt/silccrypt.[ch].
1423 * The same thing was done to silc_hash_* as for silc_cipher_*
1424 routines. Affected files lib/silccrypt/silchash.[ch].
1426 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1427 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1428 Added also silc_pkcs_[un]register[_default] functions.
1429 Removed the data_context from the PKCS API.
1431 * Added silc_hmac_register_default function to register default
1432 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1433 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1434 to unregister all hmacs at once.
1436 * Register the default ciphers, hash functions, PKCSs and HMACs
1437 if client's configuration file does not exist. The affected
1440 * The client did not load the hash functions from the SIM
1441 modules at all. Added support for this. Affected file is
1442 silc/clientconfig.c.
1444 * When decoding public key with silc_pkcs_public_key_decode, check
1445 the supported algorithm only if PKCS are registered. Affected
1446 file lib/silccrypt/silcpkcs.c. The same was done with the
1447 silc_pkcs_private_key_decode.
1449 * Fixed the SILC List routines to keep the list always in order.
1450 It used to change the list's order when traversing the list but
1451 not it preserves the order. Affected file lib/trq/silclist.h.
1453 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Added the client library to use the SilcSocketConnection's
1456 reference counter (by silc_socket_dup) to prevent the bug that
1457 the socket object may be freed underneath async operation.
1459 * The name resolv library checking fixes in the configure.in.pre.
1462 * Created new version of the protocol drafts for future
1463 development. The -03 drafts are the ones that will be changed
1464 in the trunk now and the -02 will remain as they are.
1466 * Send list of CUMODE notifys to the router when announcing
1467 the channel users to the router. Affected file silcd/server.c.
1468 If the router receiving channel founder CUMODE for a channel
1469 that already has channel founder it will send CUMODE notify
1470 to the sender to remove the channel founder rights from the
1471 announced client. Affected file silcd/packet_receive.c.
1473 * The CUMODE notify may now use Server ID as well as the entity
1474 who changes the mode. Updated protocool specs.
1476 * Updated INSTALL and README files.
1478 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1480 * New web pages in the http://silc.pspt.fi. The pages was
1485 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1487 * Implemented the [DenyConnectin] config section in the server.
1488 Added silc_server_config_denied_conn to check whether incoming
1489 connection is denied. Affected file silcd/serverconfig.[ch].
1491 * Do not check the ports when checking the incoming configuration
1492 data if the port is 0, meaning any. Affected file is
1493 silcd/serverconfig.c.
1495 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1497 * Fixed buffer overflow in silc_string_compare in the file
1498 lib/silcutil/silcutil.c.
1500 * Fixed double free in silc_server_command_leave in the file
1503 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1505 * Fixed the version checking in the server. Affected file is
1508 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Fixed the configuration data fetching when accepting new
1511 connections in the server. Affected file silcd/server.c.
1513 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1515 * Added `sender_entry' argument to the function
1516 silc_server_packet_relay_to_channel so that we can check
1517 whether some destination actually belongs to the same route
1518 the sender belongs (ie, we must not resend the packet to the
1519 sender). Affected file silcd/packet_send.[ch].
1521 * Added `servername' field to the SilcClientEntry in the server
1522 to hold the name of the server where client is from. Affected
1523 file is silcd/idlist.h.
1525 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Moved the channel message encrypting in the router betwen
1528 router connections from silc_server_channel_message to the
1529 silc_server_packet_relay_to_channel since we want to check
1530 whether we have anybody channel before encrypting anything.
1531 Affected files silcd/packet_[receive/send].c.
1533 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Fixed the [AdminConnection] server config section to support
1536 multiple entries. Affected file silcd/serverconfig.c.
1538 * Added support into the server to check the validity of the
1539 incoming connection before executing any KE or authentication
1542 * The connection configuration is now saved to the KE and
1543 connection auth protocol contexts and not fetched anymore in
1544 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1546 * The local hosts listenning address and port is also resolved
1547 now when starting the server. We want to have the socket object
1548 to include the real address and port for the listener. Added
1549 new function silc_net_check_local_by_sock into the files
1550 lib/silcutil/silcnet.[ch].
1552 * Fixed a broadcast bug in server -> do not broadcast if we
1555 * Fixed a routing bug. Do not route broadcast packets ever.
1556 Broadcast packets must be processed always and not routed since
1557 they may be destined to some other host than yourself and thus
1558 would get routed without no good reason. Affected file is
1561 * Added function silc_server_config_is_primary_route to check
1562 whether primary router connection has been configured (a router
1563 configuration that we are initiating). If there is not, we
1564 will assume that there is only two routers in the SILC network
1565 and we will use the incoming router connection as our primary
1566 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1568 * Changed the order of the broadcasting. Broadcast _after_ the
1569 packet has been processed not before. Affected file is
1572 * Fixed a [ClientConnection] parsing bug. The port was never
1573 parsed correctly thus resulting to port 0. Affected file
1574 silcd/serverconfig.c.
1576 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1577 argument and did not set the broadcast packet flag. Affected
1578 file silcd/packet_send.c. Fixed same bug in the function
1579 silc_server_send_notify as well.
1581 * If we receive NEW_ID packet for our own ID in the server, ignore
1584 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Removed the nickname from the Private Message Payload.
1589 Updated the code and the protocol specs.
1591 * Updated protocol specs for submitting to the IETF.
1593 * Tweaked the Random Number Generator a bit. Affected file
1594 lib/silccrypt/silcrng.c. Exported a new function
1595 silc_rng_[global]_add_noise which can be used to add more
1598 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Do not parse packets with different timeout when protocol
1601 is active -> may cause problem with rekey. Affected file
1604 * When server receives signoff notify it must not create
1605 new channel key if the client is on any channels since the
1606 sender of the signoff notify will create it.
1608 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Added printing of error messages during SKE protocol from the
1611 failure packet sent by server during SKE. Affected file
1614 * Removed the client's failure_callback handling with timeout
1615 and handle it immediately when received.
1617 * The SKE library returned wrong type in SUCCESS and FAILURE
1618 packets. They must be 32 bit MSB not 16 bit MSB.
1620 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Ok, rewrote the logic of the re-key and now it seems to work.
1623 I tested it on high traffic with frequent re-keys without
1624 problems. Added hmac_receive (and renamed hmac to hmac_send)
1625 in SilcClientConnection in lib/silcclient/client.h and
1626 in SilcIDListData in silcd/idlist.h. Also, removed the
1627 SilcPacketParserContext's cipher and hmac fields as they are
1628 not needed anymore and actually caused some problems when
1629 the ciphers and hmac's changed underneath the packet parser.
1631 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * If re-key protocol is active then process the incoming packets
1634 synchronously since we must assure that icoming packets encrypted
1635 with the old key is processed before the new keys is set to
1636 use. This is true other packets than for REKEY packets.
1637 Affected file silcd/server.c. The same was done to client library
1638 as well, affected file lib/silcclient/client.c.
1640 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Fixed bug in client and server to accept the force send if
1643 the packet is send from silc_[server/client]_packet_process
1644 function. Otherwise the packets are never delivered, oops.
1646 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1648 * Disable force sending of packets when REKEY protocol is active.
1649 We must assure that no packet is sent directly when rekey is
1650 performed. All packets must be sent through packet queue.
1651 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1652 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1653 function is silc_[server/client]_packet_send_real to check
1656 * Replaced the SIM paths from example config files to
1657 /usr/local/modules. Also, make install creates now
1658 /usr/local/silc/logs directory to hold all the SILC server
1661 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Made the configure.in.pre work on Solaris. Patch by salo.
1665 * Made all ciphers compatible with non-x86 machines. Defined
1666 CBC mode macros into lib/silccrypt/ciphers_def.h.
1668 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Fixed the make install.
1672 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * When MAC computation fails the silc_packet_decrypt returned 0
1675 even though it was supposed to return -1. Fixed this. The
1676 affected file is lib/silccore/silcpacket.c.
1678 * Do not replace the config files in /etc/silc (in make install)
1679 if they already exist. Affected file ./Makefile.am.
1681 * Do not send re-key packets immediately but through packet queue.
1682 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1684 * Changed silc_net_check_host_by_sock to return FALSE if the
1685 IP/DNS could not be resolved. Though, it returns the IP address
1686 now even if it could not resolve it (but returns also FALSE).
1687 Affected file lib/silcutil/silcnet.[ch].
1689 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * Added silc_pkcs_decode_identifier to decode the public key's
1692 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1693 Added also silc_pkcs_free_identifier. Added also new context
1694 SilcPublicKeyIdentifier.
1696 * Added -S option to the silc client. It is used to dump the
1697 contents of the specified public key file.
1699 * Changed the PKCS api to return the public key length when
1700 setting the public key.
1702 * Fixed a fatal bug in the public and private key file loading.
1703 Affected file lib/silccrypt/silcpkcs.c.
1705 * Execute the packet parsing for client with zero (0) timeout
1706 if the protocol is active. Affected file silcd/server.c.
1708 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1710 * Made the key generation options to the silcd program. Added
1711 -C option, equivalent to client's option.
1713 * Added new [ServerKeys] config section to the server. It
1714 configures the server's public and private key.
1716 * Defined generic Public Key Payload into the protocol
1717 specification to send specific type of public keys and
1720 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1721 public key or certificate.
1723 * Implemented the GETKEY command to the server and to the
1724 client library and on user interface.
1726 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * Made preliminary `make install' work.
1730 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Added SilcServerRekey context into silcd/idlist.h.
1734 * Added the PFS support as defined in the specification to the
1735 SKE protocol. Affected files lib/silcske/*.c.
1737 * Added `ske_group' field to the SilcServerRekey context to hold
1738 the number of the SKE group that is used with PFS in re-key.
1739 Affected file silcd/idlist.h.
1741 * Added PFS re-key support to the server. Affected file is
1744 * Added silc_protocol_cancel to cancel execution of the next
1745 state of the protocol. Affected file is
1746 lib/silccore/silcprotocol.[ch].
1748 * Added the re-key support with and without PFS to the client
1749 library. Re-key is performed once in an hour, by default.
1751 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1752 Added silc_client_rekey_callback and silc_client_rekey_final.
1753 Affected files are lib/silcclient/protocol.[ch] and
1754 lib/silcclient/client.[ch].
1756 * Removed the `hmac_key' and `hmac_key_len' fields from the
1757 SilcClientConnection structure; not needed. Affected file is
1758 lib/silcclient/client.h.
1762 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Do not ask whether user wants to use the negotiated private key
1765 for private messages, just use it. Affected file is
1766 silc/local_command.c.
1768 * Added `send_enc_key' and `enc_key_len' fields to the
1769 SilcIDListData structure since they are needed in the re-key
1770 phase. Affected file is silcd/idlist.[ch].
1772 * Implemented the simple re-key protocol into the server.
1773 Affected files silcd/server.c and silcd/protocol.[ch]. The
1774 re-key will be performed once in an hour, by default.
1776 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1777 Added silc_server_rekey, silc_server_rekey_callback and
1778 silc_server_rekey_final.
1780 * Removed Tunneled flag from the protocol. Updated the code
1781 and the specifications.
1783 * Adde `pfs' field to the SilcIDListData to indicate whether
1784 the PFS is to be performed in the re-key. Affected file is
1787 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1789 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1790 int64 of at least the xintXX size. If void * is less that 4
1791 bytes uint32 * will be used. Defined bool as boolean.
1793 * Changed _ALL_ unsigned long and unsigned int to uint32,
1794 unsgined short to uint16 in the source tree.
1796 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1797 not handle clients that has entry->data.registered == FALSE.
1798 They are not in the network anymore. Affected file is
1801 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1803 * Implemented the sending of the SERVER_SIGNOFF notify in the
1804 server. Affected file is silcd/server.c.
1806 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1807 Added also silc_notify_payload_encode_args into the
1808 lib/silccore/silcnotify.[ch].
1810 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1811 Affected file silcd/packet_receive.c.
1813 * Implemented the SERVER_SIGNOFF notify handling in the client
1814 library. Affected file lib/silcclient/client_notify.c. Also,
1815 implemnted the printing of the SERVER_SIGNOFF info to the
1816 application. Affected file silc/client_ops.c.
1818 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1819 if the deleting was successful. Affected file silcd/idlist.[ch].
1821 * Added support for public key authentication in the connection
1822 authentication protocol in the client library. Affected file
1823 lib/silcclient/protocol.c.
1825 * Changed the server's silc_idlist_get_clients_by_* interface
1826 to support already allocated array so that new entries may be
1827 added to pre-allocated array. Affected file silcd/idlist.[ch].
1828 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1829 and command replies.
1831 * All command reply functions in the server now calls the
1832 pending command callback even if error occured. This way the
1833 error will be delivered to the client as well. Affected files
1834 silcd/command.c and silcd/command_reply.c.
1836 * Fixed INFO command to return local server's info if no server
1837 was provided. Affected file lib/silcclient/command.c.
1839 * Removed RESTART command for good. Updated the code and the
1842 * Rewrote parts of the task system. It is a bit simpler now.
1843 Removed unsued task priorities. The affected files are
1844 lib/silcutil/silctask.[ch].
1846 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1848 * Moved the USERS printing from the library to the application.
1849 Affected files lib/silcclient/command.c and silc/client_ops.c.
1851 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Added channel key re-key support. The re-key is perfomed
1856 only by the router and is done once in an hour. Added `rekey'
1857 field to the SilcChannelEntry in the server. Affected files
1858 silcd/server.c and silcd/idlist.h.
1860 * Added silc_task_unregister_by_context into the file
1861 lib/silcutil/silctask.[ch].
1863 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1865 * Added SILC_UMODE_GONE mode to indicate when the client is not
1866 present in the SILC network. Added also support to the local
1867 command AWAY that will set this mode. Added support of showing
1868 "xxx is gone" in WHOIS command. The USERS command shows the
1869 gone status as well.
1871 * Fixed setting server and router operator privileges in the
1872 server's UMODE command. Affected file silcd/command.c.
1874 * Merged the SKE KE1 and KE2 payloads into one payload. The
1875 new KE payload is equivalent to the old KE2 payload.
1877 Cleaned up the SKE Start Payload parsing. It now uses the
1878 simple buffer unformatting to do the parsing. A lot faster
1881 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1882 to the SKE that is used to indicate whether both of the SKE
1883 parties should perform authentication. By default only the
1884 responder performs authentication. By setting this flag also
1885 the initiator must do authentication. By default it is unset
1886 since in normal SKE case, client to server connection, only
1887 the responder should do authentication. When doing SKE between
1888 two clients both should perform authentication. Updated the
1889 code and the protocol specs.
1891 * A little fix to IDENTIFY command in the server. Search the
1892 client first by hash not nickname. Affected file is
1895 * Fixed the silc_client_close_connection to support closing
1896 the client to client connections wihtout deleting too much
1897 data. Affected file lib/silcclient/client.c.
1899 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1900 are received if protocol used to be active but is not anymore
1901 the application would crash due to NULL pointer dereference.
1902 Affected files silcd/server.c and lib/silcclient/client.c.
1904 * Added `hash' field to the SilcClientConnection to include
1905 the hash function negotiated in the SKE protocol.
1907 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1908 to set the channel founder authentication data. A client can
1909 claim the founder rights later by providing the authentication
1910 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1911 This way the channel founder can regain the channel founder
1912 privileges even it is left the channel. This works only on
1913 local server and the client must be connected to the same
1914 server to be able to regain the founder rights. Updated the
1915 protocol specs accordingly.
1917 Added support to the CMODE command in the client to set the
1918 founder auth data. Read the README to see how to set it.
1920 Added support to the CUMODE command to claim the founder
1921 rights. Read the README to see how to do it.
1923 Added support for the founder authentication to the Channel
1924 Entry in the server. Affected file silcd/idlist.h.
1926 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1927 server's CMODE command. Affected file silcd/command.c.
1929 * Added the following new functions into lib/silccore/silcauth.[ch]:
1930 silc_auth_get_method and silc_auth_get_data.
1932 * The server now saves the remote hosts public key to the
1933 SilcIDListData pointer. Affected file silcd/protocol.c.
1935 * The normal server now does not remove the channel entry from
1936 the cache if the founder authentication data is set. It used
1937 to remove it if the founder was the last one on the channel on
1938 the server and left the channel. The auth data is saved and
1939 if the channel is re-joined later the old entry is used with
1940 the old auth data. Affected files silcd/command_reply.c and
1943 * Removed the `pkcs' field from the SilcIDListData structure
1944 in the server; it is not used. Affected file silcd/idlist.h.
1946 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1948 * Fixed packet processing on slow links. Partial packets were
1949 never re-processed because the incoming data buffer was cleared
1950 by the application. Application must not directly clear the
1951 sock->inbuf, the packet processing routines handle it. Fixed
1952 this in client library and in server.
1954 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1956 * Fixed the WHOIS and IDENTIFY send reply function to really
1957 check whether to send list or just one entry. Affected file
1960 * Cleaned up the LEAVE command's channel key distribution. The
1961 affected file silcd/command.c.
1963 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1964 can enforce the channel mode as well. In that case the ID
1965 includes the ID of the server. The code now enforces the
1966 mode change if the router have different mode than the server.
1968 * The notify client operation with CMODE_CHANGE notify can now
1969 return NULL client_entry pointer if the CMODE was not changed
1970 by client. Application must check for this.
1972 * Added <Server ID> argument to INFO command to support server
1973 info fetching by Server ID.
1975 * Added silc_server_announce_get_channel_users to get assembled
1976 packets of channel users of the specified channel. Affected
1977 file silcd/server.[ch].
1979 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1980 was freed underneath the ID Cache.
1982 * Re-announce clients when the server received CHANNEL_CHANGE
1983 notify from the router. Affected file silcd/packet_send.c.
1985 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1987 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1988 crashed since it did not handle the fact that there is no cipher
1989 called "3" and didn't check the error condition. Now fixed.
1991 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1992 flag. It can be used to send message requests.
1994 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Implemented the RESTART command in the client.
1998 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1999 notice type messages. Added notice printing to the user
2002 * The channel keys are not re-generated if the channel's mode
2003 is PRIVKEY, ie private key on the channel exists. Affected
2004 files silcd/server.c and silcd/command.c.
2006 * Fixed a little bug in channel message delivery when channel
2007 private keys are set in the server. Affected file is
2008 silcd/packet_send.c.
2010 * Changed the setting on channel->on_channel = TRUE from the
2011 silc_client_save_channel_key to the JOIN command reply. The
2012 key payload is not received if the private channel key is set.
2013 Affected file lib/silcclient/command_reply.c and the
2014 lib/silcclient/client_channel.c.
2016 * When the CMODE_CHANGE notify is sent and the channel private
2017 key mode is removed the channel key must be re-generated in
2018 other cells as well. Added this support for the router in the
2019 silcd/packet_receive.c.
2021 * Added new local command NOTICE to send notice message on
2022 channel. Affected file silc/local_command.[ch].
2024 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Added new local command ME to the client. It is used to send
2027 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2028 some action. Affected file silc/local_command.[ch].
2030 * Changed channel_message and private_message client operations
2031 to deliver the message flags to the application. Added also
2032 the `flags' arguments to the silc_client_send_channel_message
2033 and silc_client_send_private_message functions. Affected file
2036 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Redefined the Private Message Payload to support private message
2039 keys and to support the new private message flags. Updated
2040 the protocol specs. Flags makes it possible to have for example
2041 CTCP style messages.
2043 * Added new type SilcPrivateMessagePayload and defined an API
2044 for it in the lib/silcclient/silcprivate.[ch].
2046 * Tested private message private keys successfully. Tested the
2047 private message key set, unset and list commands with the new
2050 * Redefined the Channel Message Payload to include the channel
2051 message flags (equal with private message flags) to support
2052 for example CTCP style messages.
2054 * Defined some of the message (for channel and private message)
2055 flags. Updated the protocol specs and added the flags to the
2056 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2058 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2060 * Added SilcKeyAgreementStatus type to the key agreement routines
2061 to indicate the current status and error if one occured.
2062 The status types are defined in the lib/silcclient/silcapi.h.
2064 * Added new local command KEY that is used to set and unset private
2065 keys for channels, set and unset private keys for private messages
2066 with remote clients and to send key agreement requests and
2067 negotiate the key agreement protocol with remote client. The
2068 key agreement is supported only to negotiate private message keys,
2069 it currently cannot be used to negotiate private keys for channels,
2070 as it is not convenient for that purpose.
2072 * Fixed a minor pending callback setting bug in the function
2073 silc_client_get_client_by_id_resolve, now the function works.
2074 Affected file lib/silcclient/idlist.c.
2076 * Added function silc_net_get_local_port to get local bound
2077 port by socket. Added to lib/silcutil/silcnet.[ch].
2079 * Added `sockets' and `sockets_count' fields to the SilcClient
2080 object. They hold the sockets of the listenning sockets in
2081 the client. Listenning sockets may be for example the key
2082 agreement server. Affected file lib/silcclient/client.[ch].
2083 Added functions the silc_client_add_socket and the
2084 silc_client_del_socket. They are exported to the application
2087 * Added ~./silc/clientkeys to support other client's public keys.
2089 * Renamed verify_server_key client operation to verify_public_key
2090 and added one argument to indicate the type of the connection
2091 (server, client etc.).
2093 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Added silc_server_connection_auth_request to handle the
2096 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2097 silcd/packet_receive.[ch].
2099 * Added silc_server_send_connection_auth_request into the
2100 silcd/packet_send.c to send the connection auth request packet.
2102 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2105 * Fixed the public key authentication in responder side in the
2106 server. The `auth_data' pointer includes the SilcPublicKey
2107 not the path to the public key. Affected file silcd/protocol.c.
2109 * Implemented the public key authentication in the initiator side
2110 in the server. Affected file silcd/protocol.c.
2112 * Removed the [RedirectClient] config section from the server
2113 configuration. Is not needed and I don't want to implement it.
2115 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Cleaned up the CMODE command in the server. It now works
2118 correctly and supports all the modes defined in the protocol.
2119 Affected file is silcd/command.c.
2121 * Added `hmac_name' field to the SilcChannelEntry in the server
2122 to hold the default HMAC of the channel. It can be set when
2123 creating the channel (with JOIN command). Affected files
2126 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2127 type to indicate the change of the current cipher and hmac
2128 on the channel. Client can safely ignore the <cipher> argument
2129 (if it chooses to do so) since the CHANNEL_KEY packet will
2130 force the channel key change anyway. The <hmac> argument is
2131 important since the client is responsible of setting the new
2132 HMAC and the hmac key into use.
2134 * Fixed the CMODE command in the client library as well.
2136 * Tested CMODE command in router environment successfully.
2138 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Show the version of the remote client (or server) when connecting
2141 to the server. It is logged to the log file. Affected file
2142 is silcd/protocol.c.
2144 * Fixed the KILLED notify handling in the client library. The
2145 client must be removed from all channels when receiving the
2148 Also, do not remove the client entry when giving the KILL
2149 command but when the KILLED notify is received.
2151 * Removed silc_idlist_find_client_by_nickname from the server.
2152 Not needed anymore. Affected files silcd/idlist.[ch].
2154 * Implemented the CHANNEL_CHANGE notify type handling to the
2155 server. Affected file silcd/server.c.
2159 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Added silc_server_send_notify_invite to send the INVITE
2162 notify between routers.
2164 * Implemented the INVITE command correctly to the server.
2166 * Implemented the INVITE notify type handling in the server.
2168 * Implemented the INVITE command to the client library and on the
2171 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2173 * Added function silc_server_get_client_resolve to find the
2174 client entry by ID from all ID lists and then resolve it
2175 (using WHOIS) if it cannot be found. Affected file is
2178 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2180 * Implemented the BAN command to the client library.
2182 * The JOIN command in the server now checks the invite list
2185 * Changed the silc_command_reply_payload_encode_va and the
2186 silc_command_payload_encode_va to support that if argument is
2187 NULL it ignores and checks the next argument. Affected file
2188 lib/silccore/silccommand.c.
2190 * Added silc_server_send_notify_ban to send the BAN notify
2191 type between routers.
2193 * Chaned the silc_notify_payload_encode to support that if
2194 argument is NULL it ignores and checks the next argument.
2195 Affected file lib/silccore/silcnotify.c.
2197 * Tested ban lists in router environment successfully.
2199 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * Implemented BAN command to the server, in silcd/command.[ch].
2203 * Removed the BAN and INVITE_LIST modes from the CMODE command
2206 * Added function silc_string_match to regex match two strings.
2207 Affected files lib/silcutil/silcutil.[ch].
2209 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Redefined parts of the SilcChannelEntry in the server to support
2212 the new ban and invite lists.
2214 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2216 * Redefined the INVITE command. The same command can be used to
2217 invite individuals to the channel but also to manage the invite
2218 list of the channel (to add to and remove from the invite list).
2219 Updated the protocol specs.
2221 * Added new command SILC_COMMAND_BAN that can be used to manage
2222 the ban list of the channel. Updated the protocol specs.
2224 * Removed the channel modes: the SILC_CMODE_BAN and the
2225 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2226 in the CMODE command. The equivalent features are now available
2227 using INVITE and BAN commands. Updated the protocol specs.
2229 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2230 in the network about change in the current ban list. The notify
2231 type is not used by the client.
2233 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2234 support the invite lists.
2236 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2238 * Added new function silc_string_regexify that converts string
2239 including wildcard characters into regex string that can
2240 be used by the GNU regex library. Added into the file
2241 lib/silcutil/silcutil.[ch].
2243 Added silc_string_regex_combine to combine to regex strings
2244 into one so that they can be used as one regex string by
2245 the GNU regex library. Added into the file
2246 lib/silcutil/silcutil.[ch].
2248 Added silc_string_regex_match to match two strings. It returns
2249 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2251 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Imported GNU regex to the soruce tree into lib/contrib.
2254 Fixed some compiler warning from the regex.c.
2256 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2258 * Fixed MOTD command in the server to work in router environment.
2260 * Fixed the MOTD command in the client library to support
2261 the server argument in the command.
2263 * Added `nickname_len' argument to the silc_idlist_add_client
2264 in the server, as the `nickname' argument may be binary data
2267 * Added silc_idlist_get_channels to return all channels from
2270 * Implemented LIST command to the server. Affected file is
2273 * Implemented the LIST command to the client library and on the
2276 * Added [<user count>] argument to the LIST command reply.
2277 With private channels the user count is not shown.
2279 * Updated TODO and README.
2281 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * The client entry's data.registered must be TRUE even with
2284 global client entry on global client list. The data.registered
2285 is used to check whether the client is anymore in the network,
2286 for example with WHOWAS command so it must be valid.
2288 * Fixed the WHOWAS command in the server. It now actually works
2289 in router environment. Added function into silcd/command_reply.c
2290 silc_server_command_reply_whowas_save.
2292 * Added silc_idlist_purge function to the silcd/idlist.c
2293 to periodically purge the ID Cache.
2295 * Fixed INFO command in the server. It works now in router
2296 environment. Added <server name> argument to the INFO command
2297 reply. Updated the protocol specs.
2299 * Fixed minor bug in silc_idcache_purge to not purge if the
2300 expire value is zero.
2302 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2303 they were buggy because of the WHOWAS information.
2305 * Fixed local command MSG to handle the async resolving of
2306 the remote client properly. It used to fail the first MSG.
2307 Affected file silc/local_command.c.
2309 * Added `data_len' field to SilcIDCache context.
2311 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Update TODO. Todo in commands in the server.
2315 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2317 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2318 used by routers as broadcast packet to inform other routers
2319 about the changed user mode.
2321 Implemented the notify handling in the server. Affected file is
2322 silcd/packet_receive.c. Added the function
2323 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2325 * Added new generic Channel Payload and deprecated the New Channel
2326 Payload. The New Channel Payload is now the generic Channel
2329 * Added new argument `mode' to the silc_server_send_new_channel
2330 as it is required in the Channel Payload now.
2332 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2333 and created a new and real SilChannelPayload to represent the
2334 new generic Channel Payload. Implemented the encode/decode
2335 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2337 * Added silc_server_get_client_channel_list to return the list
2338 of channels the client has joined for WHOIS command reply.
2339 Affected file silcd/server.[ch].
2341 * Implemented the channel list sending in the WHOIS command reply
2342 in server and in the client.
2344 Implemented the channel list displaying on the user interface
2345 as well. Affected file silc/client_ops.c.
2347 * Added silc_channel_payload_parse_list to parse list of Channel
2348 Payloads. It returns SilcDList list of SilcChannelPayloads.
2349 Client for example can use this function to parse the list of
2350 channels it receives in the WHOIS command reply. The caller
2351 must free the list by calling silc_channel_payload_list_free.
2352 Affected files lib/silccore/silcchannel.[ch].
2354 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * Added one new argument <user mode> to the WHOIS command reply
2357 to return the mode of the user in SILC. Updated the protocol
2360 Implemented it to the server and client.
2362 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Fixed the mode printing on the user interface on joining.
2365 Affected file silc/client_ops.c.
2367 * Implemented the UMODE command and user modes in general to the
2368 client library and to the user interface.
2370 * Implemented the UMODE command to the server.
2372 * The server now sends UNKNOWN_COMMAND error status if client sends
2373 unknown command. Affected file silcd/command.c.
2375 * All server commands now handle the command identifier the right
2376 way when sending the command reply to the client. The client can
2377 use to identify the command replies with the identifier.
2379 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Added silc_server_get_client_route to resolve the route to
2382 the client indicated by the client ID. Affected file is
2385 * Added silc_server_relay_packet as general function to relay
2386 packet to arbitrary destination. This deprecates functions
2387 like _send_private_message_key, _relay_notify etc. Affected
2388 file is silcd/packet_send.[ch].
2390 Removed silc_server_send_key_agreement,
2391 silc_server_send_private_message_key and
2392 silc_server_packet_relay_notify functions from the file
2393 silcd/packet_send.[ch].
2397 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2398 server. Affected file silcd/packet_receive.[ch].
2400 * Implemented the KILL command to the client. Implemented the
2401 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2402 Affected files lib/silcclient/command[_reply].c and
2403 lib/silcclient/client_notify.c. Implemented the KILL notify
2404 printing in the user inteface.
2406 * Fixed a lot silc_parse_nick memory leaks from the client
2407 library in the file lib/silcclient/command.c.
2409 * Changed the silc_server_send_notify_on_channels's `sender'
2410 argument from SilcSocketConnection to SilcClientEntry to
2411 check the sender as entry and not as connection object and not
2412 to send to the client provided as argument. The affected file
2413 is silcd/packet_send.[ch].
2415 * The notify packets that are destined directly to the client used
2416 to not to be processed by the server. Now changed that and the
2417 server processes all notify packets. After relaying the packet
2418 to the client the notify packet is processed in the server.
2420 * The silc_server_free_client_data now checks whether there is
2421 pending outgoing traffic for the client and purges the data to
2422 the network before removing the client entry.
2424 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2426 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2427 an client is killed from the SILC Network. Updated the protocol
2430 Added new function silc_server_send_notify_killed to the
2431 silcd/packet_send.[ch].
2433 * Added function silc_server_packet_relay_notify to relay notify
2434 packets that are destined directly to a client. In this case
2435 the server does not process the notify packets but merely relays
2436 it to the client. Affected file silcd/packet_send.[ch].
2438 Added also silc_server_packet_process_relay_notify to check
2439 whereto relay the notify. Affected file is
2440 silcd/packet_receive.[ch].
2442 * Implemented the KILL command to the server.
2446 * Added the backup schema desgined last fall to the protocol
2447 specs for everyone to see. The specification is in the
2448 *-spec-xx.txt draft and the packet type definitions for the
2449 backup routers is in *-pp-xx.txt draft. Thusly, added also
2450 new packet type SILC_PACKET_CELL_ROUTERS.
2452 * A big security problem in the implementation discovered. The
2453 signoff of an client did not cause new channel key generation
2454 which it of course should've done. The channel keys must be
2455 always re-generated when client leaves (or signoffs) the channel.
2456 The silc_server_remove_from_channels funtion now handles
2457 the channel key re-generation.
2459 * Added `sender' argument to the silc_server_send_notify_on_channels
2460 to not to send the client provided as argument. Affected file
2461 silcd/packet_send.[ch].
2463 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Implemented OPER and SILCOPER commands into the server and
2468 * Added silc_auth_verify and silc_auth_verify_data to verify
2469 the authentication directly from the authentication payload.
2470 It supports verifying both passphrase and public key based
2471 authentication. Affected file lib/silccore/silcauth.[ch].
2473 * Added `hash' field to the SilcIDListData structure. It is the
2474 hash negotiated in the SKE protocol. Affected file is
2477 * Slight redesigning of the SilcAuthPayload handling routines.
2478 Do not send SilcPKCS but SilcPublicKey as argument.
2480 * Implemented the public key authentication support to the
2481 serverconfig. The public key is loaded from the provided path
2482 and saved as authentication data to void * pointer. Thus,
2483 changed the unsigned char *auth_data to void *auth_data;
2485 * Fixed SHUTDOWN command to send the reply before the server
2486 is shutdown. :) Affected file silcd/command.c.
2488 * Fixed fatal bug in CONNECT command. The hostname was invalid
2489 memory and server crashed. Affected file silcd/command.c.
2491 * Fixed fatal bug in CLOSE command. The server_entry became
2492 invalid but was referenced later in the command. Affected file
2495 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Fixed fatal bug in failure packet handling. Server ignored
2498 the failure and thus crashed when it came.
2502 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2505 that the command may be executed only once in (about) 2 seconds.
2506 The old SILC_CF_LAG flag is same but allows command bursts up
2507 to five before limiting.
2509 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2510 server code. Various commands now includes the CF_LAG_STRICT
2511 flag to disallow any kind of miss-use of the command.
2513 * Fixed the silc_buffer_unformat to not to allocate any data
2514 if the length of the data is zero. It used to allocate the
2515 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2517 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Changed the format of AdminConnection configuration section
2520 in the server. Added username of the admin to the format.
2521 Affected files silcd/serverconfig.[ch].
2523 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2524 to return admin configuration data by host, username and/or
2527 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2529 * Implemented WHOWAS command to the server. Added the functions:
2531 silc_server_command_whowas_parse,
2532 silc_server_command_whowas_send_reply,
2533 silc_server_command_whowas_from_client and
2534 silc_server_command_whowas_from_server
2536 * Added <Client ID> argument to the WHOWAS command reply. Updated
2537 the protocol specs accordingly.
2539 * Implemented WHOWAS command and command_reply to the client
2542 Implemented the WHOWAS printing on the user interface.
2544 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2546 * Added new argument to the WHOWAS command reply, the real name.
2547 It is an optional argument. Updated the protocol specs.
2549 * Added SilcIDCacheDestructor callback that is registered when
2550 the SilcIDCache is allocated. The callback is called when
2551 an cache entry in the ID Cache expires, or is purged from the
2552 cache. Added into lib/silccore/idcache.[ch].
2554 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2555 to destruct the client entries when the cache entry expires.
2556 Other ID Cache's in server and in the client library ignores
2559 * If the ID Cache entry's `expire' field is zero then the entry
2560 never expires. Added boolean `expire' argument to the
2561 silc_idcache_add function in the lib/silccore/idcache.[ch].
2562 If it is TRUE the default expiry value is used.
2564 * Added silc_server_free_client_data_timeout that is registered
2565 when client disconnects. By default for 5 minutes we preserve
2566 the client entry for history - for WHOWAS command.
2568 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Added support to the server to enforce that commands are not
2571 executed more than once in 2 seconds. If server receives
2572 commands from client more frequently, timeout is registered
2573 to process the commands. Affected file silcd/command.c.
2574 Added new function silc_server_command_process_timeout.
2576 * Changed NICK_NOTIFY handling in client library to check that
2577 if the client's nickname was changed, so there is no need to
2578 resolve anything from the server.
2580 * Removed error printing from the WHOIS and IDENTIFY commands.
2581 If error occurs then it is ignored silently in the client library.
2582 The application, however, may map the received error to
2583 human readable error string. The application currently maps
2584 the NO_SUCH_NICKNAME error to string.
2586 * Made the command status message public to the application. Moved
2587 them from lib/silcclient/command_reply.c to
2588 lib/silcclient/command_reply.h. The application can map the
2589 received command status to the string with the
2590 silc_client_command_status_message function.
2592 * Added check to the server to check that client's ID is same
2593 as the Source ID in the packet the client sent. They must
2596 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Added dist-bzip hook to the Makefile.am to make bzip2
2599 compressed distributions.
2601 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Server now enforces the maximum length for the nickname and
2604 the channel as protocol specification dictates. 128 bytes for
2605 nickname and 256 bytes for channel name.
2607 * Moved the WHOIS printing to the application. The client libary
2608 does not print out the WHOIS information anymore, the application
2609 must do it. Renamed silc_client_command_reply_whois_print to
2610 the silc_client_command_reply_whois_save.
2612 The client's idle time is also sent to the application now, and
2613 the idle is shown on screen.
2615 * Added silc_client_command_reply_identify_save to save the
2616 received IDENTIFY entries.
2618 * Do not check for channel private keys in message sending and
2619 reception if the channel does not have the PRIVKEY mode set.
2620 Affected file lib/silclient/client_channel.c.
2622 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2625 just surfaced after chaning the JOIN procedure.
2627 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Added silc_client_get_clients_by_list to get client entries
2630 from Client ID list, that is returned for example by JOIN
2631 and USERS command replies. The application should use this
2632 function for example when JOIN command reply is received to
2633 resolve the clients already on the channel (library does not
2634 do that anymore as USERS command reply is not used in the JOIN
2635 procedure anymore). Affected files lib/silcclient/silcapi.h and
2636 lib/silcclient/idlist.c.
2638 * JOIN command reply and USERS command reply returns now SilcBuffer
2639 pointers instead of unsigned char pointers when returning
2640 the client list and mode list.
2642 * Added <Client ID> argument to the JOIN command reply, mainly
2643 for the server to identify for which client the command was
2644 originally sent. Updated protocol specs accordingly.
2646 * Added SilcDlist private_key pointer to the SilcChannelEntry
2647 in the client to support the channel private keys. Affected
2648 file is lib/silcclient/idlist.h.
2650 * Added SilcChannelPrivateKey argument to the function
2651 silc_client_send_channel_message so that application can choose
2652 to use specific private ke if it wants to. If it is not provided,
2653 the normal channel key is used, unless private keys are set.
2654 In this case the first (key that was added first) is used
2655 as the encryption key.
2657 * Implemented the support for channel private key handling.
2658 Implemented the following functions:
2660 silc_client_add_channel_private_key,
2661 silc_client_del_channel_private_keys,
2662 silc_client_del_channel_private_key,
2663 silc_client_list_channel_private_keys and
2664 silc_client_free_channel_private_keys
2666 Affected file lib/silcclient/client_channel.c.
2668 * Added the support for the private keys in the channel message
2669 sending and encryption and in the message reception and
2670 decryption. Affected funtions are
2671 silc_client_send_channel_message and silc_client_channel_message.
2673 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2675 * Added SKE's key verify callback to the client library's
2676 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2678 * Removed the statement that server (or router) must send USERS
2679 command reply when joining to the channel so that the client
2680 knows who are on the channel. Instead, the client list and
2681 client's mode list is now sent in the JOIN command reply to the
2682 client who joined channel. This is better solution.
2684 * Added function silc_server_get_users_on_channel and function
2685 silc_server_save_users_on_channel to the silcd/server.[ch].
2687 * Removed function silc_server_command_send_users from the
2690 * Do not show topic on the client library anymore. The topic is
2691 sent in the command reply notify to the application and the
2692 application must show the topic now.
2694 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Added client searching by nickname hash into the IDENTIFY and
2697 WHOIS commands in the server as they were clearly missing from
2698 them. Affected file is silcd/command.c.
2700 * Fixed a bug in private message receiving in the client library.
2701 The remote ID was freed and it wasn't supposed, now it is
2704 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Minor fix to the channel payload; allocate the data area, as it
2707 needs to be of specific length.
2709 * If the key agreement port is zero then the operating
2710 system will define the bound port. Affected files are
2711 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2713 * Added new function silc_channel_payload_decrypt into the file
2714 lib/silccore/silcchannel.[ch].
2716 * Moved the channel message etc, check from silc_packet_decrypt
2717 to applications. The library calls now a generic
2718 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2719 when the packet is either normal or special. This was done to
2720 allow more wide range of checking that was not allowed when
2721 the code was in library. Now applications can do virtually any
2722 checks to the packet and return to the library the decision how
2723 the packet should be processed. Affected files are
2724 lib/silccore/silcpacket.[ch].
2726 Added silc_server_packet_decrypt_check to the server and
2727 silc_client_packet_decrypt_check to the client library.
2729 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2730 to send with specified source and destination information.
2732 * Channel message delivery between routers was broken after the
2733 channel key distribution was fixed earlier. The channel key
2734 was used be to distributed to other routers as well which is not
2735 allowed by the protocol. Now this is fixed and channel keys
2736 really are cell specific and the channel message delivery between
2737 routers comply with the protocol specification.
2739 * Fixed various commands in server to check also the global list
2740 for the channel entry and not just the local list. The affected
2741 file silcd/command.c.
2743 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Added assert()s to buffer formatting and unformatting routines
2746 to assert (if --enable-debug) when error occurs. Affected
2747 file: lib/silcutil/silcbuffmt.c.
2749 * Changed to auto-reconnect to check whether the remote host is
2750 router and register the re-connect timeout if it is. It used
2751 to check that whether we are normal server, but router must do
2752 auto-reconnect with another router as well. Affected file
2755 * Removed the [<key len>] option from CMODE command as the cipher
2756 name decides the key length, nowadays. See the defined ciphers
2757 from the protocol specification.
2759 * Added [<hmac>] option to the CMODE command to define the HMAC
2760 for the channel. Added SILC_CMODE_HMAC channel mode.
2762 * Added [<hmac>] option for the JOIN command so that user can
2763 select which HMAC is used to compute the MACs of the channel
2766 * Added Hmac field to the Channel Message Payload. The integrity
2767 of plaintext channel messages are now protected by computing
2768 MAC of the message and attaching the MAC to the payload. The
2769 MAC is encrypted. Now, it is clear that this causes some
2770 overhead to the size of the packet but rationale for this is that
2771 now the receiver can verify whether the channel message decrypted
2772 correctly and also when private keys are set for the channel the
2773 receiver can decrypt the packet with several keys and check from
2774 the MAC which key decrypted the message correctly.
2776 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2777 lib/silccrypt/silccipher.[ch].
2779 * Added silc_hash_len to return the digest length into the
2780 lib/silcrypt/silchash.[ch].
2782 * Rewrote parts of Silc Channel Payload interface in the
2783 lib/silccore/silcchannel.[ch]. The encode function now also
2784 encrypts the packet and parse function decrypts it.
2786 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * Fixed a minor formatting bug in the SKE's key material processing.
2789 It actually might have processed the keys wrong way resulting
2792 * Redefined the mandatory HMAC algorithms and added new algorithms.
2793 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2794 and hmac-md5 truncated to 96 bits. The mandatory is now
2795 hmac-sha1-96. Rest are optional (including the one that used
2796 to be mandatory). Rationale for this is that the truncated HMAC
2797 length is sufficient from security point of view and can actually
2798 make the attack against the HMAC harder. Also, the truncated
2799 HMAC causes less overhead to the packets. See the RFC2104 for
2802 * Added new [hmac] configuration section. The SKE used to use
2803 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2804 is of course wrong. The official names that must be proposed in
2805 the SKE are the ones defined in the protocol specification
2806 (hmac-sha1-96 for example). The user can configure any hmac
2807 using any hash function configured in the [hash] section. At
2808 least, the mandatory must be configured.
2810 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2812 * Added HMAC list to the SKE proposal list. It has now both
2813 hash algorithm list and HMAC list. This makes the protocol
2814 incompatible with previous versions. The SKE now seems to work
2815 the way it is supposed to work, for the first time actually.
2817 * Defined plain Hash algorithms to the protocol specification.
2820 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Implemented support for key agreement packets into the server.
2823 Added functions silc_server_key_agreement and
2824 silc_server_send_key_agreement. Other than these functions,
2825 server has nothing to do with this packet.
2827 * Added support for private message key packets into the server.
2828 Added functions silc_server_private_message_key and
2829 silc_server_send_private_message_key.
2833 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2834 called in the protocol's final callback instead in the END
2835 protocol state. This makes a little more sense and in the same
2836 time in client we can use the same protocol routines for normal
2837 key exchange and to key agreement packet handling as well.
2839 * Added to both client's and server's KE protocol context the
2840 SilcSKEKeyMaterial pointer to save the key material. We will
2841 bring the key material to the protocol's final callback by doing
2842 this. The final callback must free the key material.
2844 * Added SKE's packet_send callback into client's KE protocol
2845 context so that the caller can choose what packet sending function
2846 is used. This way we can use different packet sending when
2847 doing normal SKE when doing key agreement packet handling (in
2848 the key agreement packet handling we do not want to encrypt
2851 * Implemented the responder side of the key agreement routines
2852 in the client. The client can now bind to specified port and
2853 accept incoming key negotiation. The key material is passed
2854 to the application after the protocol is over.
2856 * Implemented the processing of incoming Key Agreement packet
2857 in the client. Added function silc_client_key_agreement to
2860 * Implemented the intiator side of the key agreement routines
2861 in the client. The client can now initiate key agreement with
2862 another remote client. The key material is passed to the
2863 application after the protocol is over.
2865 * Created client_keyagr.c to include all the key agreement
2868 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2869 SILC_TASK_CALLBACK except that it is not static.
2871 * Created client_notify.c and moved the Notify packet handling
2872 from the client.[ch] into that file.
2874 * Created client_prvmsg.c and moved all private message and
2875 private message key routines from the client.[ch] into that file.
2877 * Create client_channel.c and moved all channel message and
2878 channel private key routines from the client.[ch] into that file.
2880 * Changed silc_client_get_client_by_id_resolve to resolve with
2881 WHOIS command instead of IDENTIFY command, in the file
2882 lib/silclient/idlist.c.
2884 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Implemented the SKE's responder side to the Client library.
2888 * When FAILURE is received to the protocol do not trust it
2889 blindly. Register a timeout to wait whether the remote closes
2890 the connection as it should do it, only after that process the
2891 actual failure. This was changed to both client and server.
2893 * Added client_internal.h to include some of the structures
2894 there instead of client.h in lib/silcclient/.
2896 * Added function silc_task_unregister_by_callback to unregister
2897 timeouts by the callback function.
2899 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Some "Incomplete WHOIS info" errors has been appearing on the
2902 log files. Took away the entry->userinfo check from WHOIS
2903 reply sending. The entry->userinfo is now " " if client did not
2904 provide one. I thought this was fixed earlier but something
2905 is wrong still. Let's see if the error still appears.
2907 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Fixed a minor bug in the login when the channel key is
2910 re-generated in the server. It used to generate the key in
2911 wrong order and thus caused problems in the channel traffic.
2913 * Fixed a minor bug in channel key distsribution after
2914 KICK command. The key was not sent to the router even though
2917 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added silc_ske_process_key_material_data as generic routine
2920 to process any key material as the SILC protocol dictates. The
2921 function is used by the actual SKE library but can be used by
2922 applications as well. This relates to the private message keys
2923 and the channel private keys since they must be processed the
2924 same way the normal SILC session keys. The protocol dictates
2925 this. Affected files: lib/silcske/silcske.[ch].
2927 Added also silc_ske_free_key_material to free the
2928 SilcSKEKeyMaterial structure.
2930 * Defined silc_cipher_set_key function to set the key for
2931 cipher without using the object's method function. The affected
2932 files: lib/silccrypt/silccipher.[ch].
2934 * Implemented silc silc_client_add_private_message_key,
2935 silc_client_add_private_message_key_ske,
2936 silc_client_del_private_message_key,
2937 silc_client_list_private_message_keys and
2938 silc_client_free_private_message_keys functions in the
2941 Added functions silc_client_send_private_message_key to send
2942 the Private Message Key payload and silc_client_private_message_key
2943 to handle incoming Private Message Key payload.
2945 * Added Cipher field to the Private Message Key payload to set
2946 the cipher to be used. If ignored, the default cipher defined
2947 in the SILC protocol (aes-256-cbc) is used.
2949 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Removed lib/silcclient/ops.h file.
2953 Redefined parts of the SILC Client Library API. Created new
2954 file silcapi.h that deprecates the ops.h file and defines the
2955 published Client Library API. Defined also private message key
2956 API and channel private key API into the file.
2958 This is the file that the application must include from the
2959 SILC Client Library. Other files need not be included by
2960 the application anymore.
2962 * Added new key_agreement client operation callback and also
2963 defined the Key Agreement library API for the application.
2965 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2968 is used by clients to request key negotiation between another
2969 client in the SILC network. If the negotiation is started it
2970 is performed using the SKE protocol. The result of the
2971 negotiation, the secret key material, can be used for example
2972 as private message key.
2974 Implemented the Key Agreement payload into the files
2975 lib/silccore/silauth.[ch].
2977 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Redefined ciphers for the SILC protocol. Added some new ciphers
2980 and defined the key lengths for the algorithms. Changed the
2981 code accordingly. The default key length is now 256 bits.
2983 * Fixed SKE key distribution function silc_ske_process_key_material
2984 when the key length is more than 128 bits. The default key
2985 length in SILC is now 256 bits.
2987 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2988 to indicate unsupported algorithm.
2990 * Renamed rijndael.c to aes.c and all functions as well.
2992 * Fixed a long standing channel key setting bug in client library.
2993 Weird that it has never surfaced before.
2995 * Fixed bug in channel deletion. If the entire channel is removed
2996 then it must also delete the references of the channel entry
2997 from the client's channel list as the client's channel entry and
2998 the channel's client entry share same memory.
3000 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Implemented CONNECT and SHUTDOWN commands in the client.
3004 * Implemented CLOSE command to the client.
3006 * Added the function silc_idlist_find_server_by_name into the
3007 files silcd/idlist.[ch].
3009 Added the function silc_idlist_find_server_by_conn into the
3010 files silcd/idlist.[ch].
3012 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * DIE command was renamed to SHUTDOWN. Updated the both code
3017 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3018 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3020 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3023 * Added function silc_server_create_connection function to create
3024 connection to remote router. My server implementation actually
3025 does not allow router to connect to normal server (it expects
3026 that normal server always initiates the connection to the router)
3027 so the CONNECT command is only good for connecting to another
3030 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3033 or some other client was kicked from the channel.
3035 Implemented the handling of the notify type to both client
3038 Implemented silc_server_send_notify_kicked to send the KICKED
3039 notify. It is used to send it to the server's primary router.
3041 * Implemented the KICK command into server and client.
3043 * Added `query' argument to the silc_idlist_get_client function
3044 to indicate whether to query the client from server or not if
3047 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3048 to indicate that the client is not channel founder.
3052 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Removed the rng context from SilcPacketContext structure and
3055 changed that the packet routine uses the Global RNG API.
3057 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Added support for quit message that client can "leave" on the
3060 channel when it quits the SILC. It is ditributed inside the
3061 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3063 Added silc_server_free_client_data that will take the
3064 signoff message as argument.
3066 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3068 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Updated parts of the protocol specification to keep it up
3073 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3076 payloads in one packet.
3078 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3079 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3080 use now the new List flag.
3082 * Also deprecated the following packet types: REPLACE_ID,
3083 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3085 * Added list support for Notify packet in server.
3087 * Added silc_server_send_notify_channel_change to send the
3088 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3089 the silc_server_send_replace_id.
3091 * Added silc_server_send_notify_nick_change to send the
3092 NICK_CHANGE notify type. Deprecates the function
3093 silc_server_send_replace_id.
3095 * Added silc_server_send_notify_join to send the JOIN notify type.
3096 Deprecates the function silc_server_send_new_channel_user.
3098 * Added silc_server_send_notify_leave to send LEAVE notify type.
3099 Deprecates the function silc_server_send_remove_channel_user.
3101 * Added silc_server_send_notify_cmode and
3102 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3103 types. Deprecates the silc_server_send_set_mode function.
3105 * Added SERVER_SIGNOFF notify type to indicate that server has
3106 quit. This means that all clients on the channel from that
3107 server will drop. This can be also used when netsplit happens.
3109 Deprecated REMOVE_ID packet type since it is not needed anymore
3112 Added silc_server_send_notify_server_signoff to send the
3113 SERVER_SIGNOFF notify type. Deprecates the function
3114 silc_server_send_remove_id.
3116 Added also silc_server_send_notify_signoff to send the
3117 SIGNOFF notify type.
3119 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3120 SILC protocol from this day on. Changed the protocol
3121 specification as well.
3123 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3124 notify type. It is used between routers to notify about
3125 topic changes on a channel.
3127 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3130 * Partly updated the protocol specification to comply with the
3131 changes now made. It is still though a bit outdated.
3133 * The JOIN notify type now takes one extra argument <Channel ID>.
3134 The packet used to be destined to the channel but now the
3135 JOIN type may be sent as list thus it is impossible to
3136 destine it to any specific channel. By adding this argument
3137 it is again possible.
3139 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Added CREDITS file. The CHANGES and CREDITS file will appear
3142 in the distribution as well.
3144 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3147 types in the server's silcd/packet_receive.c.
3149 * Implemented CMODE and CUMODE to work in router environment.
3151 * Fixed minor encoding and decoding buglet from the
3152 lib/silccore/silcmode.c.
3154 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3157 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3159 * Changed all SilcConfigServer* and silc_config_server* to
3160 SilcServerConfig* and silc_server_config*, respectively.
3163 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Associated the ID (client or server ID) to the Authentication
3166 Payload to avoid any possibility of forging. Updated the
3167 protocol specification and the code accordingly.
3169 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * The RSA key length is now save to the RsaKey context in the
3172 key generation process in lib/silccrypt/rsa.c. The key length
3173 is now used to figure out the maximum size of the block allowed
3174 to be encrypted/signed.
3176 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3177 is equivalent to the silc_mp_mp2bin but does not allocate any
3180 * Changed silc_mp_mp2bin API to take length argument. If it is
3181 non-zero then the buffer is allocated that large. If zero, then
3182 the size is approximated using silc_mp_sizeinbase, which however
3185 * Created Global RNG API which is global RNG that application can
3186 initialize. After initializing, any routine anywhere in the
3187 code (including library) can use RNG without allocating a new
3188 RNG object. This was done to allow this sort of use of the
3189 RNG in code that has no chance to allocate RNG object. All
3190 applications currently allocate this and many routines in the
3191 library use this. Affected file lib/silccrypt/silcrng.[ch].
3193 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3194 it to use the Global RNG API.
3196 * Defined Authentication Payload into protocol specification that
3197 is used during SILC session to authenticate entities. It is
3198 used for example by client to authenticate itself to the server
3199 to obtain server operator privileges.
3201 Implemented this payload into the lib/silccore/silcauth.[ch].
3202 Implemented also routines for public key based authentication
3203 as the new protocol specification dictates.
3205 Moved definitions of different authentication methods from
3206 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3208 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3209 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3210 silc_pkcs_verify_with_hash functions into the file
3211 lib/silccrypt/silcpkcs.[ch].
3213 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * The client entry's userinfo pointer must be always valid.
3216 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3217 will fail since it requires the userinfo. Now, the userinfo
3218 is allocated as "" if actual userinfo does not exist. Actually,
3219 it must exist and it is totally Ok to drop client connections
3220 that does not announce the userinfo. However, we will make
3221 this workaround for now.
3223 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3224 to return the remote port by socket.
3226 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3229 SILC_SERVER_PENDING_EXEC and added an new macro
3230 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3231 data or when error occurs while processing the pending command.
3233 Added new argument `destructor' into silc_server_command_pending
3234 and to the SilcServerCommandPending object. This destructor is
3235 now called after calling the pending callback or if error occurs
3236 immediately. If error occurs the actual pending callback won't
3237 be called at all - only the destructor. The destructor may be
3238 NULL if destructor is not needed.
3240 All this applies for client library code as well. Similar
3241 changes were made there as well for the pending commands.
3243 In the client, the application must now allocate the
3244 SilcClientCommandContext with the silc_client_command_alloc
3247 * Added reference counter to the SilcServerCommandContext. Added
3248 function silc_server_command_alloc and silc_server_command_dup
3251 Same type of functions added to the client library for the same
3254 * Removed the cmd_ident from IDListData away since it is now
3255 global for all connections. It is the command identifier used
3256 in command sending and with pending commands. The affected file
3259 * Added reference counter to the SilcSocketConnection objecet to
3260 indicate the usage count of the object. The object won't be
3261 freed untill the reference counter hits zero. Currently only
3262 server uses this, and client ignores it. The client must be
3263 set to use this too later. The affected files are
3264 lib/silccore/silcsockconn.[ch]. Added also the function
3265 silc_socket_dup to increase the reference counter.
3267 This was mainly added because it is possible that the socket
3268 is removed underneath of pending command or other async
3269 operation. Now it won't be free'd and proper DISCONNECTING
3270 flags, etc. can be set to avoid sending data to connection that
3271 is not valid anymore.
3273 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3274 the connection. After that it sets SILC_SET_DISCONNECTED.
3275 It is, however, possible that the socket data is not still freed.
3276 The silc_server_packet_process now checks that data is not
3277 read or written to connection that is DISCONNECTED. The socket
3278 get's freed when the reference counter hits zero.
3280 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Changed the client operation API: channel_message operation's
3283 `sender' is now the client entry of the sender, not the nickname
3284 and the `channel' is the channel entry, not the channel name.
3286 In the private_message operation the `sender' is now also the
3287 client entry of the sender not the nickname.
3289 Affected file is lib/silcclient/ops.h and all applications
3290 using the client operations.
3292 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Moved the calling of ops->connect() from connect_to_server_final
3295 into receive_new_id functin since that is the point when the
3296 client is actually allowed to send traffic to network. The
3297 affected file is lib/silcclient/client.c.
3299 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3302 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3303 (if needs broadcasting) instead of broadcasting the packets one
3304 by one which would make a burst in the network traffic.
3306 * Added `broadcast' argument to the functions in silcd/server.[ch]
3307 silc_server_create_new_channel[_with_id] to indicate whether
3308 to send New Channel packet to primary router.
3310 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Added new function into the silcd/server.[ch] files:
3313 silc_server_create_new_channel_with_id to create new channel with
3314 already existing Channel ID.
3316 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3317 lib/silccore/silcpacket.h. This packet is used t send list of
3318 Set Mode payloads inside one packet. Server uses this to set
3319 the modes for the channels and clients on those channels, that it
3320 announced to the router when it connected to it. The protocol
3321 specification has been updated accordingly.
3323 * The silc_server_new_channel did not handle the packet coming
3324 from normal server as it normally does not send that. However,
3325 when it announces its channels it does send it. Implemented
3326 the support for that.
3328 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3329 into the file lib/silccore/id.h.
3331 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Fixed memory leaks in the functions silc_idlist_del_client,
3334 silc_idlist_del_channel and silc_idlist_del_server in the file
3335 silcd/idlist.c. All of those leaked like a sieve.
3337 * Fixed some small memory leaks in the client's function
3338 silc_client_notify_by_server.
3340 * Added functions into silcd/server.c: silc_server_announce_clients,
3341 silc_server_announce_channels and silc_server_announce_server.
3342 These functions are used by normal and router server to announce
3343 to its primary router about clients, channels and servers (when
3344 router) that we own. This is done after we've connected to the
3347 These functions effectively implements the following packet types:
3348 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3349 and SILC_PACKET_NEW_ID_LIST.
3351 * Added new functions into the silcd/packet_receive.[ch]:
3352 silc_server_new_id_list, silc_server_new_channel_list and
3353 silc_server_new_channel_user_list to handle the incoming
3354 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3356 * Added support of changing Channel ID in the function
3357 silc_server_replace_id. If the server that announces a channel
3358 to the router already exists in the router (with same name but
3359 with different Channel ID), router is responsible to send
3360 Replace ID packet to the server and force the server to change
3361 the Channel ID to the one router has.
3363 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3364 client that the Channel ID has been changed by the router. The
3365 normal server sends this to the client. Client must start using
3366 the new Channel ID as the channel's ID.
3368 Implemented handling of this new type into lib/silcclient/client.c
3369 into the function silc_client_notify_by_server.
3371 * Added new function silc_idlist_replace_channel_id into the files
3372 silcd/idlist.[ch] to replace the Channel ID.
3374 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Call silc_server_command_identify_check always when processing
3377 the IDENTIFY command in silcd/command.c
3379 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3382 send keepalive packets. The packet can be sent by clients,
3383 servers and routers.
3385 Added function silc_socket_set_heartbeat into the file
3386 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3387 If not set, the heartbeat is not performed. The actual
3388 heartbeat is implemented in the low level socket connection
3389 library. However, application is responsible of actually
3392 Added silc_server_send_heartbeat to send the actual heartbeat
3393 packet into silcd/packet_send.[ch]. Server now performs
3394 keepalive with all connections.
3396 * Added silc_task_get_first function into lib/silcutil/silctask.c
3397 to return the timeout task with shortest timeout. There was a bug
3398 in task unregistration that caused problems. TODO has been
3399 updated to include that task system must be rewritten.
3401 * The client library will now resolve the client information when
3402 receiving JOIN notify from server for client that we know but
3403 have incomplete information.
3405 * Rewrote parts of silc_server_remove_from_channels and
3406 silc_server_remove_from_one_channel as they did not remove the
3407 channel in some circumstances even though they should've.
3409 * Encryption problem encountered in server:
3411 The LEAVE command used to send the Channel Key packet to the
3412 router immediately after generating it. However, the code
3413 had earlier sent Remove Channel user packet but not immediately,
3414 ie. it was put to queue. The order of packets in the router
3415 was that Channel Key packet was first and Remove Channel User
3416 packet was second, even though they were encrypted in the
3417 reverse order. For this reason, MAC check failed. Now, this
3418 is fixed by not sending the Channel Key packet immediately but
3419 putting it to queue. However, this is more fundamental problem:
3420 packets that are in queue should actually not be encrypted
3421 because packets that are sent immediately gets encrypted
3422 actually with wrong IV (and thus MAC check fails). So, packets
3423 that are in queue should be encrypted when they are sent to
3424 the wire and not when they put to the queue.
3426 However, the problem is that the current system has not been
3427 designed to work that way. Instead, the packet is encrypted
3428 as soon as possible and left to the queue. The queue is then
3429 just purged into wire. There won't be any fixes for this
3430 any time soon. So, the current semantic for packet sending
3433 o If you send packet to remote host and do not force the send
3434 (the packet will be in queue) then all subsequent packets to the
3435 same remote host must also be put to the queue. Only after the
3436 queue has been purged is it safe again to force the packet
3439 o If you send all packets immediately then it safe to send
3440 any of subsequent packets through the queue, however, after
3441 the first packet is put to queue then any subsequent packets
3442 must also be put to the queue.
3444 Follow these rules and everything works fine.
3446 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Added new function silc_server_remove_clients_by_server to
3449 remove all client entries from ID list when the server connection
3450 is lost. In this case it is also important to invalidate all
3451 client entires as they hold the invalid server entry. This
3452 fixes fatal bug when server has lost connection and will reconnect
3455 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Made some sanity checks to silc_server_daemonise like to check
3458 whether the requested user and group actually exists.
3460 * Added sanity check to SKE's silc_ske_responder_finish to check
3461 that the public and private key actually is valid.
3463 * Invalidate the client's nickname when receiving Replace ID
3464 packet and the Client ID is being replaced. This means that the
3465 server will query the nickname if someone needs it (client)
3468 * Sort the ID Cache in client library when the ID Cache data
3469 has changed (needs sorting).
3471 * Do not allow for SILC client to create several connections to
3472 several servers. The client does not support windows right now
3473 and generating multiple connections causes weird behaviour.
3475 Irssi-silc client does support windows and can handle several
3476 connections without problems, see: www.irssi.org and SILC plugin.
3478 * Fixed some places where client was added to the IDList. The
3479 rule of thumb is following (in order to get everything right):
3480 If the client is directly connected local client then the
3481 `connection' argument must be set and `router' argument must be
3482 NULL to silc_idlist_add_client function. If the client is not
3483 directly connected client then the `router' argument must
3484 bet set and the `connection' argument must be NULL to the
3485 silc_idlist_add_client function.
3487 * The funtion silc_server_packet_send_local_channel actually did
3488 not check whether the client was locally connected or not. It
3489 does that now. Fixed a bug related to LEAVE command.
3491 * Fixed Remove Channel User payload parsing bug in server's
3492 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3494 * The server's silc_server_save_channel_key now checks also the
3495 global ID list for the channel as it might not be in the local
3496 list. Fixed a bug related to LEAVE command.
3498 * Is this the end of the [<unknown>] buglet that has been lurking
3499 around for a long time? A little for loop fix in server's
3500 silc_server_command_whois_parse that is used by both IDENTIFY
3501 and WHOIS command. At least, this was a clear bug and a cause
3502 of one type of [<unknown>] buglet.
3504 * WHOIS and IDENTIFY commands call the function
3505 silc_server_command_[whois/identify]_check function even if
3506 we are not router server.
3508 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added --with-gmp configuration option. If set the GMP
3511 is always compiled in the SILC source tree. If not set then
3512 it is checked whether the system has the GMP3 installed. If
3513 it has then the GMP won't be compiled (the system's headers
3514 and library is used), if it doesn't have it then the GMP is
3515 compiled in the SILC source tree.
3517 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Changed RSA private exponent generation to what PKCS #1
3520 suggests. We try to find the smallest possible d by doing
3521 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3522 not security fix but optimization.
3524 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Added new config entry [Identity] to fork the server and run
3527 it as specific user and group. A patch from Bostik.
3529 * Imported Dotconf configuration library into lib/dotconf.
3530 This will be used to create the SILC configuration files later.
3531 It will appear in the distsribution after this commit.
3533 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * A big code auditing weekend happening. Auditing code for
3536 obvious mistakes, bugs and errors. Also, removing any code
3539 Removed files for being obsolete:
3541 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3542 inline in the file lib/silcutil/silcbuffer.h)
3544 o lib/silcutil/silcbufutil.c (the header has inline versions)
3546 Changed code to fix possible error conditions:
3548 o The buffer formatting routines now check that the destination
3549 buffer really has enough space to add the data. This applies for
3550 both buffer formatting and unformatting
3551 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3552 unformatting was changed to accomodate following rules:
3553 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3554 sent to the function while XXX_*STRING will not allocate or copy
3555 the data into the buffer. Instead it sets the pointer from the
3556 buffer into the pointer sent as argument (XXX_*STRING used to
3557 require that the pointer must be allocated already). This change
3558 makes this whole thing a bit more consistent and more optimized
3559 (note that the data returned in the unformatting with XXX_*STRING
3560 must not be freed now). The routines return now -1 on error.
3562 o Tried to find all code that use buffer_format and buffer_unformat
3563 and added return value checking to prevent formatting and
3564 especially unformatting errors and possible subsequent fatal
3567 o Changed ske->x and ske->KEY to mallocated pointers in
3568 lib/silcske/silcske.h. Fixed possible data and memory leak.
3570 o Added return value checking to all *_parse* functions. Fixed
3571 many memory leaks as well.
3573 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3574 so that buffer overflows would not happen. All code now also
3575 checks the return value as it can fail.
3577 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Added reconnection support to server if the normal server looses
3580 its connection to the router (for example if router is rebooted).
3581 The server performs normal reconnection strategy implemented
3582 to the server. Affected file silcd/server.c.
3584 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Added new packet type SILC_PACKET_SET_MODE that is used to
3587 distribute the information about changed modes (for clients,
3588 channels and clients channel modes) to all routers in the
3589 network. Updated the protocol specification accordingly.
3591 Added functions into silcd/packet_send.c and
3592 silcd/packet_receive.c: silc_server_send_set_mode,
3593 silc_server_set_mode.
3595 Added new files silcmode.[ch] into lib/silccore that implements
3596 the encoding and decoding of Set Mode Payload. Added new type
3597 SilcSetModePayload. Moved the definitions of different modes
3598 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3600 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Oops, a little mistake in server's connection authentication
3603 protocol. The protocol is not ended with FAILURE but with
3604 SUCCESS if the authentication is Ok. :) Affected file is
3607 * Implemented NICK_CHANGE notify handling in server in the file
3608 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3609 the local clients on the channel. After the changing nickname
3610 in router environment snhould work and the [<unknown>] nickname
3611 should appear no more.
3613 The silc_server_replace_id function that receives the Replace ID
3614 payload now sends the NICK_CHANGE notify type also in the file
3615 silcd/packet_receive.c
3617 * Changed WHOIS and IDENTIFY command to support the maximum amount
3618 of arguments defined in protocol specs (3328 arguments). This
3619 fixed a bug that caused problems when there were more than three
3622 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Added extra parameter, command identifier, to the
3625 silc_client_send_command so that explicit command identifier
3628 Changed that ID list routines uses specific command identifier
3629 when sending WHOIS/IDENTIFY requests to the server so that they
3630 can be identified when the reply comes back.
3632 Affected files lib/silcclient/command.[ch],
3633 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3635 * Added `sender' argument to silc_server_packet_send_to_channel
3636 to indicaet the sender who originally sent the packet to us
3637 that we are now re-sending. Ignored if NULL. Affected file
3638 silcd/packet_send.[ch].
3640 * Added some server statistics support in silcd/server_internal.h
3641 SilcServerStatistics structure and around the server code. Also
3642 send some nice statistics information when client is connecting
3645 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Fixed channel ID decoding in server's JOIN command reply in
3648 silcd/command_reply.c
3650 * Fixed braodcasting of replace ID payload to not to send it if
3651 we are standalone server in silcd/packet_receive.c.
3653 * Fixed all channel message sending routines to not to send
3654 packets to clients that has router set, since they are routed
3655 separately in the same function earlier. Affects file
3656 silcd/packet_send.c and all channel packet sending functions.
3658 * In USERS reply, res_argv[i] are not allocated, the table
3659 is allocated. Thus changed that free the table, not its
3662 * In server's whois_check and identify_check if the client is
3663 locally connected do not send any WHOIS commands - they are not
3666 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Fixed some minor bugs in client when sending WHOIS command. The
3669 arguments was in wrong order.
3671 * Removed statis function add_to_channel from server in
3672 silcd/command.c that was previously used with the joining but
3675 * Tested USERS command in router environment successfully with two
3676 routers, two servers and two clients.
3678 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Reorganized the USERS command and command reply in client library
3681 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3682 When the command is given by user we register a pending command
3683 callback that will reprocess the command after the reply has been
3684 received from the server. When reprocessing the packet we then
3685 display the information. Thus, the USERS information is displayed
3686 now in the command callback instead of in the command reply
3687 callback. The processing of the command is same as previously
3688 when server has sent the command reply in the JOINing process.
3690 * Added to USERS command in silcd/command_reply.c to join the client,
3691 we didn't use to know about, to the channel after we've created
3692 a client entry for it. Also, for clienet we did know already still
3693 check whether it is on the channel or not and add it if not.
3695 * Removed silc_server_command_join_notify as the function and its
3698 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Changed the client's pending command handling to the same as the
3701 server's pending command handling. It is also now possible to
3702 execute command reply functions from other command reply
3703 function as the function callbacks for commands and command
3704 replies are one and same. The pending commands are not static
3705 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3706 in client connection context. Thus, pending commands are server
3707 connection specific as it is convenient.
3709 Changed the function silc_client_command_pending and
3710 silc_client_command_pending_del and added new function
3711 silc_client_command_pending_check. Removed the
3712 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3715 * Added cmd_ident, current command identifier, to the client
3716 connection context in lib/silcclient/client.h to keep track on
3717 command identifiers used in command sending. Client's command reply
3718 function handling now supports the mandatory command identifiers.
3720 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3721 funtions in client to fully support pending command callbacks.
3723 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3724 as one of the arguments to the application in the command reply
3727 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3728 before first releasing SILC but came back. Now it is removed again
3729 and should come back nomore. The FORWARDED flag was used only
3730 by the JOINing procedure by forwarding the command packet to router.
3731 Now, the JOINing procedure has been changed to more generic (due
3732 to various router environment issues) and FORWARDED is not needed
3733 anymore for anything. The protocol specification is yet to be
3736 Now, removed silc_server_packet_forward from server and the flag
3737 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3739 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Renamed NAMES command to USERS command. The NAMES was named that
3742 due to historical reasons. Now it is renamed. Also, rewrote
3743 parts of the USERS command. The nickname list is not sent anymore
3744 by the server. Only Client ID and mode lists are sent in the USERS
3745 command. Changed this also to the protocol specification.
3747 The client now resolves the names and stuff after it receives
3748 the USERS list from the server when joining to the channel.
3750 * WHOIS and IDENTIFY commands has been changed to support multiple
3751 Client ID's per command. One can now search for multiple users
3752 in the network by sending only one WHOIS or IDENTIFY command.
3753 Changed the code and the protocol specifications.
3755 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3756 uses silc_server_command_whois_parse to parse the request. */
3758 * If normal server, do not parse the WHOIS and IDENTIFY requests
3759 before sending it to the router. Saves some time.
3761 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Fixed JOIN command on client library. Wrong number of arguments
3764 used to crash the client.
3766 * Added silc_server_channel_has_global function to check whether
3767 channel has global users or not.
3769 * Added silc_server_channel_has_local function to check whether channel
3770 has locally connected clients on the channel.
3772 * The silc_server_remove_from_one_channel now checks whether the
3773 channel has global users or not after given client was removed from
3774 the channel. It also checks whether the channel has local clients
3775 on the channel anymore. If it does not have then the channel entry
3776 is removed as it is not needed anymore.
3778 * The silc_server_notify now checks on JOIN notify whether the joining
3779 client is one of locally connected or global. If it is global then
3780 the channel has now global users on the channel and that is marked
3781 to the channel entry. Also, it now saves the global client to
3782 global list who is joining and JOINs it to the channel. This is
3783 for normal server, that is.
3785 Changed silc_server_send_notify_on_channel,
3786 silc_server_packet_relay_to_channel and
3787 silc_server_packet_send_to_channel check if we are normal server
3788 and client has router set (ie. global client) do not send the
3789 message to that client, as it is already routed to our router.
3791 * Implemented LEAVE notify type handling in silc_server_notify
3794 * Tested LEAVE command in router environment successfully. Tested
3795 with two routers, two servers and two clients.
3799 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3801 * Implemented SIGNOFF notify type handling in silc_server_notify
3804 * silc_server_remove_id now removes the client entry from all channels
3805 it has joined and thusly sends SIGNOFF notify type.
3807 * Rewrote the NAMES list generation in server by removing two excess
3808 loops. The lists are created now inside one loop.
3810 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * silc_server_remove_channel_user checks now also global list
3813 for channel and client.
3815 * silc_server_new_channel_user checks now both local and global
3816 list for channel and client. Fixed a bug in client id decoding.
3817 Used to decode wrong buffer.
3819 * silc_server_channel_message checks now both local and global
3820 list for channel entry.
3822 * Tested channel joining (hence JOIN) in router environment
3823 successfully. Tested with two routers, two servers and two
3826 * Tested channel message sending in router environment successfully.
3828 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Added silc_server_save_channel_key into server.[ch] to save the
3831 received channel key in Channel Key payload processing. It is
3832 also used in JOIN command reply handling.
3834 Equivalent function silc_client_save_channel_key added into
3835 client.[ch] into client library.
3837 * Changed JOIN command reply to send information whether the channel
3838 was created or not (is existing already) and the channel key
3839 payload. Changed protocol specs accordingly.
3841 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3842 the request was sent by ID and not by nickname. Crashed on
3845 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3848 now correctly save the received data.
3850 * silc_server_free_sock_user_data now notifies routers in the
3851 network about entities leaving the network.
3853 At the same time implemented functions silc_server_remove_id
3854 and silc_server_send_remove_id to receive and send REMOVE_ID
3855 packets. The packet is used to notify routers in the network
3856 about leaving entities. The ID removed will become invalid in
3859 * Added function silc_idlist_del_server into server. Removes and
3860 free's server entry from ID list.
3862 * silc_server_private_message function now checks, if we are router,
3863 that the destination ID really is valid ID, naturally.
3865 * In router when NEW_ID packet is received (for new client) the
3866 hash of the Client ID is saved in the ID Cache but the
3867 client->nickname is set to NULL, instead of putting the hash
3870 IDENTIFY command now also checks that client->nickname must be
3871 valid. If it is not if will request the data from the server who
3872 owns the client. Added new function
3873 silc_server_command_identify_check.
3875 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3876 to set the command to already allocated Command Payload.
3878 * Tested private message sending in router environment with two
3879 routers, two servers and two clients. Fixed minor bugs and now
3882 * Fixed segfault from client's NAMES command. Used to crash if
3885 * Forwarded packets must not be routed even if it is not destined
3886 to the receiver. Changed server code comply with this.
3888 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Added `require_reverse_mapping' boolean value to ServerParams
3891 structure. If TRUE (not default) the server will require that
3892 the connecting host has fully qualified domain name.
3894 If the reverse mapping is not required and hostname could not be
3895 found the IP address is used as hostname.
3897 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Implemented version string checking to both client and server.
3900 The check is incomplete currently due to the abnormal version
3901 strings used in development version of SILC.
3903 * Changed all command functions in server to use the new
3906 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Changed char *data to unsigned char *data in ID Cache system to
3909 support binary data as ID Cache data. Changed code to support
3910 binary data in lib/silccore/idcache.c.
3912 * Renamed silc_server_packet_relay_command_reply to
3913 silc_server_command_reply as it is normal packet receiving
3914 function. Rewrote the function to accept command replys for
3915 servers and not only for clients.
3917 * Mark remote router always as registered server if we are connecting
3918 to it. Otherwise, commands sent by the router to us are ignored.
3920 * All ID List find routines now returns the ID Cache Entry pointer
3921 as well if requested.
3923 * WHOIS command works now in router environment, tested with two
3924 routers, two servers and two clients.
3926 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3927 in router environment (as it is almost equivalent to WHOIS) but
3928 hasn't been tested thoroughly. Added new functions:
3930 silc_server_command_identify_parse
3931 silc_server_command_identify_send_reply
3932 silc_server_command_identify_from_client
3933 silc_server_command_identify_from_server
3935 * Disabled route cache adding because adding two different ID's with
3936 same IP replaces the old cache entry thus giving wrong route.
3937 The entry->router->connection is always the fastest route anyway
3938 so route cache may not be needed. Of course, new routes maybe
3939 established after receiving the ID when the entry->router->connection
3940 might not be anymore the most optimal.
3942 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Add route cache for received ID for fast routing.
3946 * Added silc_server_packet_route to route received packet on router
3947 that is not destined to us.
3949 * Renamed silc_server_get_route to silc_server_route_get.
3951 * Added id_string and id_string_len fields into SilcServer to
3952 include encoded ServerID for fast comparing without excess
3953 encoding of the ID's.
3955 * Cleaned up WHOIS command on server side. Added following static
3958 silc_server_command_whois_parse
3959 silc_server_command_whois_check
3960 silc_server_command_whois_send_reply
3961 silc_server_command_whois_from_client
3962 silc_server_command_whois_from_server
3964 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3965 arguments in command replies. All command functions should be
3966 updated to use this macro.
3968 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Minor typo fixes on command reply handling on server.
3972 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Added silc_server_command_add_to_channel internal routine to add
3975 the client to the channel after router has created the channel and
3976 sent command reply to the server.
3978 * Added generic silc_server_send_command to send any command from
3981 * Use static buffer with ID rendering instead of duplicating data.
3983 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Fixed a channel user mode bug when joining to a channel server gave
3986 everybody channel founder rights, oops.
3988 * We mark ourselves as the router of the incoming server connection
3989 if we are router ourselves. This way we can check in some packet
3990 sending functions whether it is locally connected server. For
3991 incoming router connections we put NULL.
3993 * For router sending packets locally means now always sending the
3994 packet cell wide; to local clients and local servers. For normal
3995 server sending packet locally means sending it to only local
3998 * Fixed the JOIN command to really work in router environment. If the
3999 channel is created it is always created by the router. Router is
4000 also responsible of making the initial joining to the channel,
4001 sending JOIN notify to the sending server and distributing
4002 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4003 does not exist server doesn't do anything else but forward the
4004 command to the router which performs everything.
4006 * Added silc_server_send_channel_key function to send the Channel Key
4009 * Added silc_server_create_channel_key to create new channel key. The
4010 channel key is now re-generated everytime someone joins or leaves
4011 a channel, as protocol dictates. Note: channel->key_len is the
4014 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4017 packet_receive.[ch] to separate packet sending and receiving
4018 routines. The server.[ch] now includes everything else including
4019 actual packet processing (writing and reading data) and other
4022 Renamed silc_server_private_message_send_internal to
4023 silc_server_send_private_message. The routine is still though
4024 used only to relay private messages as server does not send
4025 private messages itself.
4027 Renamed silc_server_new_channel to silc_server_create_new_channel
4028 and added new function sicl_server_new_channel that handles the
4029 incoming New Channel packet. Added also new sending function
4030 silc_server_send_new_channel to send New Channel Payload.
4032 * Added new function silc_server_notify to process incoming notify
4033 packet to the server/router. Server may then relay the notify
4034 to clients if needed.
4036 * Added new function silc_server_new_channel_user to process incoming
4037 New Channel User packet. Router will redistribute the packet and
4038 send JOIN notify to its local clients and locally connected servers
4039 if needed. Normal server will send JOIN notify to its local client
4040 on same channel when received this packet. Added also corresponding
4041 sending function silc_server_send_new_channel_user to sent the
4044 * Added boolean route argument to send_notif_to_channel and
4045 packet_send_to_channel functions to attempt to route the packet
4046 if it is TRUE and send only locally if it is FALSE.
4048 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * silc_server_replace_id now broadcasts the received replace ID
4051 packet if it is not broadcast packet already. The router must
4052 broadcast to inform other routers about changed ID.
4054 * Added backpointer to server's router into SilcServer context in
4055 silcd/server_internal.h.
4057 * Fixed silc_server_packet_broadcast to send correct broadcast
4060 * The channel key is now distributed to the local client as soon
4061 as it is received from the router (in router environment) so that
4062 no other packet may be sent for the channel until client has
4065 * silc_server_remove_channel_user now broadcasts the received
4066 Remove Channel User packet if it is not broadcast packet already.
4067 The router must broadcast to inform other routers about removed
4070 * Added users field into SilcPacketContext that is a reference count
4071 of the context. One can increase the reference count by calling
4072 silc_packet_context_dup which is now changed to just increase the
4073 reference count instead of duplicating the data. The reference
4074 count is decresed by calling silc_packet_context_free that will
4075 free the data after the reference count hits zero.
4077 For now on the packet context and everything allocated into it
4078 (including the raw packet from network) must be freed by calling
4079 the new silc_packet_context_free function. Added also new function
4080 silc_packet_context_alloc that must be used now to allocate the
4081 context. This also means that if a routine is asynchronous from
4082 silc_[client/server]_packet_parse_type the packet context must
4083 be duplicated by calling silc_packet_context_dup. Otherwise it
4084 gets free'd after silc_[client/server]_packet_parse_type returns.
4085 Also, one must remember that if packet is duplicated then its
4086 reference count must be decresed by calling the free function as
4087 many times as it was duplicated.
4089 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4090 from both client and server.
4092 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Made joining to a channel working in router environment.
4096 * Cleaned up JOIN command on server side and create function
4097 silc_server_command_join_channel internal routine to make the
4100 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Changed silc_command_pending list to SilcDList. Also, added
4103 `ident' field to SilcServerCommandPending structure to identify
4104 the reply and to call correct callback.
4106 Added silc_server_command_pending_check function to replace the
4107 corresnponding macro. The silc_command_pending list is not
4110 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4111 to set identifier to previously allocated Command Payload. It
4112 is used to set identifier for command when resending Command
4115 * Added silc_command_payload_encode_payload to encode Command
4116 Payload buffer from SilcCommandPayload structure.
4118 * Added silc_argument_payload_encode_payload to encode Argument
4119 payload buffer from SilcArgumentPayload structure.
4121 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Changed WHOIS command to support router connection on server side.
4124 The whois request is always sent to router unless the server is
4125 standalone server. After server has received the reply from the
4126 router will it send the reply to the client.
4128 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4129 broadcast received broadcast packet. The function is used only
4130 by router. The broadcast packet is always sent to the router's
4133 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4134 render given ID to printable string, for log files for example.
4136 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Made basic router to router connections working. At least they
4139 can now connect to each other but nothing really works the way
4140 they are supposed - yet.
4142 * Added new initiator token to RouterConnection configuration
4143 file in silcd/serverconfig.[ch]. It is used to tell whether we
4144 are the initiator to the remote router or whether we'll expect
4145 the other end to connect.
4147 * Moved registering of listener task to silc_server_init, hence
4148 the server starts listenning as soon as it is run, even if it
4149 does not have connections to other routers. Let's see how well
4152 * Changed default connection retry timeouts for more suitable in
4155 * Removed cipher and such arguments from silc_idlist_add_client
4156 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4157 Added new function silc_idlist_add_data to add the keys and stuff
4160 * Added SilcIDListData structure and added it to SilcClientEntry
4161 and SilcServerEntry as their first field in the structure. This
4162 way we can explicitly cast the ID entries to the SilcIDListData
4163 structure and get common data for the entries. In past, we had
4164 to first check what type of connection it is and then cast it to
4165 correct ID entry type. Now, we can directly cast the opaque
4166 pointer to the SilcIDListData (no matter what ID entry it actually
4167 is) and get the data needed.
4169 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4172 in some circumstances even if threre were timeout tasks, though not
4173 IO tasks, but tasks anyway. Now fixed.
4175 * Defined SilcServerConnection structure to hold connection specific
4176 stuff about directly connected servers and routers. The definition
4177 is currently in silcd/server_internal.h. I thought about having
4178 a bit more important role fro this struct but for now it is used
4179 only when connecting to other server (or router actually).
4181 * Added connecting retry support in server when connecting to
4182 router(s). The retry feature implement exponential backoff
4183 algorithm. Also, added SilcServerParams structure to hold default
4184 parameters for server. For now, it include these retry settings
4185 and are hard coded. After server is moded to be as Silc Server
4186 Library this structure will be more important.
4188 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Changed client librarys channel->clients table to SilcList and
4191 changed code accordingly.
4193 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Changed client's channel table to SilcList and changed code
4196 accordingly. Also changed SilcChannelClientEntry to include back-
4197 pointer to the channel so that client entry can use that structure
4198 as list as well and we have fast cross-reference to the channel.
4199 This change dramatically decreased the complexity of channel
4200 handling with client entry and vice versa (removed one extra
4201 loop when searching for channel entry from many functions).
4203 * Changed server->sim from table to SilcDList and changed code
4206 * NAMES command can now be used from user interface. It will show
4207 the user list on the channel, neatly.
4209 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4210 Code now saves realname of the user if it becomes available.
4212 * Renamed configure.in to configure.in.pre and made ./prepare
4213 script to automatically add correct version string to
4214 configure.in which it creates from configure.in.pre.
4216 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * NAMES command reply now shows users mode with the nickname when
4221 * Moved silc_client_ch[u]mode[_char] functions from
4222 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4223 place sucks, they are utility functions and should be in some
4226 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4228 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4231 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Added TRQ (efficient deque and list library) into lib/trq. This is
4236 a very good list library that is currently used in the SILC. Defined
4237 SilcList API over the library because I didn't like the API very
4238 much. See lib/trq/silclist.h for the API and examples of how to
4239 use the API. Fixed various places in the code to use the new
4240 SilcList API. The SilcList is meant for lists that has a structure
4241 already defined as a list. It is not suitable to add just some
4242 context to the list (in TRQ, the context is the list actually).
4244 So, I defined SilcDList that can be used for the purpose where
4245 predefined list structure does not exit. This can be used as
4246 such list. Now some context just can be added to the SilcDList.
4247 Currently this list is not used in the SILC just yet, though there
4248 are a lot places where this can replace dynamically allocated
4249 tables and I will fix these places, later, to use SilcDList.
4250 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4251 and use TRQ internally).
4253 Also fixed some annoying warning messages that the original TRQ
4254 code generated. Also minor changes to TRQ's Makefile.in.
4256 * Added support for querying by Client ID to both WHOIS and
4257 IDENTIFY commands into server, as required by the protocol.
4259 * Removed method function pointers from SilcBuffer structure. They
4260 weren't used to anything and just increased the context size for
4261 no good reason. This change also made silc_buffer_alloc and
4262 silc_buffer_free functions inline functions.
4264 * Disabled command flooding detection support until it's fixed so
4265 that it accepts commands in but does not execute them more than once
4268 * Added silc_net_localhost(), to return local hostname, into
4269 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4270 that must be initialized before calling silc_client_init.
4272 * Added new function: silc_server_send_notify_on_channels to send
4273 notify messages to all channels client has joined. It is assured
4274 that the message is sent only once per client.
4276 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4277 lib/silcutil/silcutil.[ch] as silc_format function. The new
4278 function is generic and is used by server as well, not only by
4279 the logging routines.
4281 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4282 the provided version string was not acceptable. Added new function:
4283 silc_ske_check_version into lib/silcske/silcske.h. The function
4284 must be implemented by the application (client or server) and it
4285 does not reside in the SKE library. The function checks the version
4286 string remote end sent.
4288 * Added back pointers (to opaque context and to SilcSocketConnection)
4289 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4291 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4292 duplicate packet context structure.
4294 * Changed `notify' client operation to send same arguments as client
4295 receives from server except for ID's. ID's are mapped to correct
4296 ID entry and that is returned. Also, if channel entry is not sent
4297 by server but the notify is for channel the channel entry is sent
4298 to application (otherwise application doesn't know that it is for
4299 channel (library gets it from packet's Destination ID)).
4301 * Added silc_client_remove_from_channels into client library to
4302 remove a client from all channels it has joined to. Used when
4303 received SIGNOFF notify from server. Added also new function
4304 silc_client_replace_from_channels to replace old ID entry with
4305 new ID entry on all channels. Used when received NICK_CHANGE
4308 * Fixed ID Cache list handling in silc_idlist_get_client in
4309 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4310 to get (or query) client by ID.
4312 * Updated TODO list.
4314 * Added connection authentication status message defined by the
4315 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4316 support for these into the code in client and server side.
4318 * Added generic function silc_client_send_command to send any command
4319 with variable argument list. Application should use this function
4320 to send commands if the command functions provided by the library
4321 does not suite for the application's user interface needs.
4323 * Added new `failure' client operation. Application is notified about
4324 received failure packet if client is executing a protocol. In this
4325 case the protocol's execution has failed.
4327 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4328 is required by the protocol.
4330 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4331 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4334 * Added status flag to SilcSKE object to indicate realtime status
4335 of the SKE protocol.
4337 * Application receives now exactly same command reply arguments as
4338 the library receives from server. However, if ID is received the
4339 corresponding ID entry is returned to the application (eg. Client
4340 ID is mapped to correct SilcClientEntry entry and that is returned).
4341 Changed command_reply client operation due to this change.
4343 * Changed all ID's in commands and in command replys as ID Payloads.
4344 Change affected both client and server side codes.
4346 All ID's sent in SILC network (with execption of ID's in SILC
4347 Packet header) are sent in ID Payload to support variable length
4350 * Server now notifies nick changes and notifies all clients on
4351 the channels about the new nickname (about the new Client ID,
4354 * Implemented CMODE command to change channel modes. Supports all
4355 channel modes defined by the protocol specs except ban and invite
4356 lists. (Also, private channel key mode is supported but support for
4357 setting private channel key in client is missing, thus, this mode
4358 has no effect on client side (except that server requires that the
4359 client uses private channel key and normal channel traffic does not
4362 Also, invite mode works per se, but INVITE command does not work
4363 yet correctly, so you can set channel as invite only channel but
4364 inviting clients to the channel does not work (it is yet to be
4365 thought what's the best way to do it).
4367 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4368 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4369 Implemented CUMODE command to change user's mode on the channel.
4370 Supports all modes defined by the protocol specs.
4372 * Added NAMES command reply to return users modes on the channel.
4374 * Removed unnecessary and slow ciphers from lib/silccrypt.
4376 * Set SO_KEEPALIVE option to connection sockets by default.
4378 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4380 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4381 redefined the Notify Payload into protocol specs.
4383 * Added silc_id_payload_parse_id to get ID directly from raw
4386 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4389 accept searching by Client ID as well.
4391 * Added support for LEAVE and SIGNOFF notify types in client library.
4393 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4394 to parse ID Payload from raw data.
4396 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Added flags parameter into silc_ske_assemble_security_properties
4399 function in lib/silcske/silcske.[ch].
4401 * Changed notify client operation to fit better for notify messages
4402 sent by server. The notify payload received from server is now
4403 passed to the application (after parsing it to SilcNotifyPayload).
4404 It is application's responsibility to retrieve the arguments
4405 from the payload and show the message the way it wants. The message
4406 sent by server is implementation specific.
4408 * Changed public keys to comply with the protocol specification.
4409 Old public keys are not supported anymore and are not compatible.
4411 * Removed nickname from Channel Payload as the latest draft removed
4412 it. The client must resolve the nickname from the NAMES command
4413 reply received when it joined the channel.
4415 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4417 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Fixed some errors in protocol specification drafts.
4421 * Created lib/silccore/silcnotify.c to implement Notify Payload
4422 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4423 generic payloads described by protocol specifications. The file
4424 includes implementations for ID Payload and Argument Payload.
4426 * Changed Command Payload implementation to use the new Argument
4427 Payload. Changed command_xxxx_payload to command_payload_xxxx
4428 to comply with SILC coding conventions.
4430 * Added suppport for Argument Payload handling in Notify Payload
4431 implementation as protocol requires it. Added the new support
4432 into server and client lib as well.
4434 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Added support for multiple nicknames on same channel. [n] is
4437 added locally to the nickname if there are more than one same
4438 nicknames on the channel.
4440 * Server now sends all nicknames that matched WHOIS request.
4441 Client also shows the list received from server.
4443 * Added TOPIC command to client side. User can now set and show
4444 current topic on channel.
4446 * Added MOTD command to client and server. Also, server sends the
4447 motd when client connects to the server.
4449 * Changed version strings to comply ISO 8601.
4451 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Fixed protocol error handling in client library. It should now
4454 cope even if the SKE fails for some reason.
4456 * Made new protocol specification drafts for submitting to IETF.
4458 * Implemented TOPIC command to server in silcd/command.c.
4460 * Added two new notify types into lib/silccore/silcnotify.h:
4461 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4462 notify nickname change and topic setting/change on a channel.
4464 * API change of command_reply operation in client library. The
4465 application gets now the status type received from server as well.
4467 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4471 * Cras fixed and optimized the packet handling even further and
4472 it should work now. Minor change to the prototype of function
4473 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4475 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Added new function into lib/silcutil/silcschedule.[ch]:
4478 silc_schedule_with_fd to select() a specified fd. The function
4479 returns after timeout expires or data arrives or goes. The
4480 function is used by packet routines to wait that all data is
4481 received from network.
4483 * Fixed data reading from network in lib/silccore/silcpacket.c.
4484 The code now assures that all data is read from the fd and then
4485 continues packet processing. This was a bug fix since the code
4486 used to drop some data in some circumstances.
4488 * Added new function into lib/silcclient/client.[ch]:
4489 silc_client_start_key_exchange to start key exchange after
4490 connection has been established to server. The code internally
4491 now uses this funtion but its main purpose was to provide it
4492 for applications that perform their own connecting. After
4493 application has created a connection it merely calls this
4494 function to start the key exchange between client and server.
4495 The library takes care of everything else after that.
4497 Updated also lib/silcclient/README to explain the usage of
4500 * Do not send to application information that connection has
4501 been established. Application gets notified it by connect
4504 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Applied cras's patch to add silc_schedule_one function. The
4507 function runs scheduler once and returns.
4509 * Fixed the scheduler after cras messed it up. The timeout
4510 handling works now as it's supposed to work.
4512 * Added into lib/silccore/ silcnotify.h to include notify
4513 message types support. Changed silc_server_send_notify*
4514 functions, in server.[ch], to support those new notify types.
4515 Added the support for the notify types into client library,
4516 as well. Added new notify client operation into ops.h in
4519 * Changed silc_server_packet_send_to_channel to send normal
4520 packets instead of just channel message packets. The function
4521 is now used to send the notify packets to channels. It is not
4522 used to send channel message packets anymore, as server never
4525 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4526 va_arg()s as it seems to require it nowadays. I guess, if SILC
4527 is compiled with older va_arg() the new code should work anyway.
4529 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Splitted core library. Core library (lib/silccore) includes
4532 now only SILC protocol specific core (and common) components.
4533 Created new utility library (lib/silcutil) that includes more
4534 generic purpose stuff. The stuff for util library was taken
4535 from the old core library. This was minor and easy split.
4537 * Created SILC Client Library (lib/silcclient) that includes
4538 implementation of the SILC client without user interface. This
4539 was major move from silc/ directory. The code has been changed
4540 so that it is transparent towards the user interface. The
4541 silc/ directory includes now the same user interface as before
4542 and it uses the new client library. Read lib/silcclient/README.
4543 Basicly, the client library performs everything else related
4544 to SILC except user interface handling. Also, configuration
4545 files are considered to be part of user interface and library
4546 does not handle them.
4548 This change also changed a lot of structures, function naming etc.
4549 Most important change was that SilcClientWindow object was
4550 renamed to SilcClientConnection in the client library. Created
4551 also new file lib/silcclient/ops.h. Also added new files
4552 silc/local_command.[ch] and silc/client_ops.[ch].
4554 All these changes were made to make it easier for user interface
4555 designers to create what ever user interface for the SILC client
4558 It is also expected that the server will be moved to lib
4559 directory as well and SILC Server Library will be created;
4560 sometimes in the future.
4562 * Removed Local commands from lib/silccore/silccommand.h as
4563 they are application specific and new client library does not
4564 handle any of those anymore.
4566 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4567 old client implementation in silc/.
4569 * Added support for callback functions in SILC_LOG_* macros.
4570 Application can now set its own callbacks that will be called
4571 instead of using the default functions that will always print
4572 the debug messages to stderr (or stdout). Also, debugging can
4573 now be disabled by setting silc_debug to FALSE and re-enabled by
4574 setting it to TRUE. Note, that logging will still work even
4575 if debugging is disabled.
4577 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4578 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4579 silc_log_reset_debug_callbacks.
4581 * To enable debugging in silc client one must give now -d
4582 option on command line.
4584 * Changed silc_schedule_init to automatically allocate task queues
4585 if they are not allocated before calling it.
4587 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Added GMP 3.1 into math library.
4591 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4594 a channel in SILC network. The packet is used by servers and
4595 routers to notify other routers that user has left a channel.
4596 This little feature was missing until now. Added the feature
4597 to protocol specification as well.
4599 Added functions: silc_server_send_remove_channel_user and
4600 silc_server_remove_channel_user into server.[ch].
4602 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4603 lib/silccore/silcpacket.h. However, they are not implemented
4606 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Fixed joining to a channel and sending channel messages
4609 between server and router. The channel message sending should
4610 now work inside a cell.
4612 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Fixed the private message sending between server and router.
4615 The private message sending should now work inside a cell.
4617 * Added silc_server_replace_id into server.[ch] to replace
4618 existing ID in the SILC network.
4620 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4621 and silc_idlist_replace_server_id into idlist.[ch] in server.
4623 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Fixed the server to server connections. Server can again now
4626 connect to router. Router to router connections probably does
4629 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added dynamic protocol registering support. Now protocols can
4632 registered and unregistered on the fly. Patch by cras.
4634 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Added lib/contrib directory to hold routines that some platforms
4637 don't have but are needed by SILC.
4639 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4640 into lin/contrib to provide getopt() and getopt_long() for
4641 those who don't have it.
4643 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Added AWAY command to client. When away message is set and
4646 client receives a private message packet the client automatically
4647 replies to the sender with the away message.
4649 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4650 bug seemed to be the cause of recent problems when compiling
4653 * Added version detection support to SKE protocol specification
4654 and added the new changes to the SKE implementation as well.
4655 There were other minor changes in the SKE protocol as well.
4657 Many changes in lib/silcske/silcske.[ch] and in
4658 lib/silcske/payload.[ch].
4660 * Added ^U functionality, clear input line. Patch from cras.
4662 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Mainly small bugfixes on core library. Fixed some debugging
4665 logging and buffer overflow in silclog.c.
4667 * Updated config.sub and config.guess on the distribution tree.
4669 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Added command lagging support in server. Client may execute
4672 commands now only once in two seconds.
4674 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Optimized packet reception. MAC computation and checking is now
4677 also more optimized. A lot previously duplicated code is now
4678 used as generic by both client and server.
4680 * Fixed key pair generation in clientutil.c
4682 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Added into lib/silccore/silcbufutil.[ch] new function;
4685 silc_buffer_realloc.
4687 * Moved generic packet sending/encryption functions to
4688 lib/silccore/silcpacket.[ch] from client and server. Some
4689 rewriting of the functions.
4691 * Moved all generic packet reception/decryption functions to
4692 lib/silccore/silcpacket.[ch] from client and server. The
4693 packet processing is now much cleaner in both client and server.
4694 These were major changes in both client and server.
4696 * Created many common functions in server to do packet sending.
4697 Previously code were duplicated a lot, this has been removed
4700 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Rewrote major parts of the ID cache system. Don't know
4703 whether it is better now or not but at least the API is more
4706 * Major rewrite on ID cache stuff on client because of the ID
4707 cache API changes. Added idlist.c to client.
4709 * Also major rewrite on ID cache stuff on server as well.
4710 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4711 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4712 in hand, instead they are all put into the ID cache system now.
4713 All server_idlist_* routines uses ID cache now instead of
4714 traversing its own lists (those lists does not exist anymore).
4715 SilcIDList though still exists. Also, SilcXXXEntry's are
4718 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Finally made the SKE implementation compliant to the protocol
4721 specification. All mp integers are now binary encoded as
4722 opposed being HEX encoded.
4724 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4727 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4728 functions: silc_[encode/decode]_pem. Also added function
4729 silc_encode_pem_file to PEM encode with newlines ('\n') for
4732 * SILC public keys are now encoded either PEM or binary. Same
4733 option is for private keys as well. By default private keys
4734 are binary encoded and public keys PEM encoded. Silly HEX
4735 encoding were removed.
4737 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4738 function to create fingerprints.
4740 * Fixed a bug in SHA1; does not change the original data anymore.
4742 * Partly implemented INFO command on client and server side.
4743 Fixed CLEAR command. Changes to SERVER command; show current
4744 server(s) when giving command without arguments. Added
4745 VERSION command to client.
4747 * Added check to server that unregistered connections cannot
4748 execute commands (unless it is specificly allowed).
4750 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Fixed screen refresh.
4754 * Fixed channel joining bug from client. On some circumstances
4755 client tried to join to a channel it had already joined.
4757 * Added public key verification process into client's protocol.c.
4758 The client now verifies the public key from user and saves
4759 it into ~./silc/serverkeys/ directory.
4761 Added into: clientutil.[ch]: silc_client_verify_server_key.
4763 * Changed SKE protocol's silc_ske_initiator_finish function
4764 to accept callback function that verifies the received public
4765 key. Removed old silc_ske_verify_public_key function.
4767 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4770 silc_pkcs_private_key[_data]_set.
4772 * Made the password and public authentication more cleaner in
4773 server's protocol.c.
4775 * Removed historic and obsolete protocol `channel_auth' from
4776 both client and server.
4778 * Removed wrong way of sending command status messages from
4779 server to client in server's command.c. The old way violated
4780 protocol specification.
4782 Changes to silccore/silccommand.[ch]: removed
4783 silc_command_encode_status_payload -> not needed anymore,
4784 changed silc_command_encode_payload_va to accept extra
4785 argument on variable argument list. The argument type must
4786 now be provided to the function. Also, added new function:
4787 silc_command_encode_reply_payload_va which is same as
4788 normal command_encode_payload_va except command status type
4789 is provided as extra argument.
4791 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Added ~./silc directory handling. The directory includes the
4794 public and private keys for the client.
4796 Added silc_client_check_silc_dir, silc_client_create_identifier
4797 and silc_client_load_keys.
4799 * Implemented SILC protocol compliant public key. Added public
4800 and private key saving to and loading from files.
4802 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4803 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4804 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4805 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4806 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4808 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4809 silc_pkcs_load_[public/private]_key.
4811 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Added silc_server_get_route (route.[ch]) to get connection
4814 data for the fastest route for given ID.
4816 * Implemented INVITE command on client and server. The command
4817 were re-defined in the SILC Protocol Specification and the
4818 implementation now complies with the specification.
4820 * Implemented PING command on client and server.
4822 * Implemented NAMES command on client and server. The server side
4823 supports currently only normal server not router server yet.
4824 Some changes to NAMES definition in SILC protocol specification.
4826 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Implemented LEAVE command on client and server.
4830 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4831 again. This change was made to the protocol as well. Server
4832 should not violate the protocol specification anymore.
4834 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4837 was tested. SOCKS4 was not but should work anyway.
