- Slightly improve randomness of /dev/random emulation.
* sigproc.h (hold_everything::ischild): Declare as reference. (hold_everything::hold_everything): Store address of caller's notion of "ischild".
2013-09-25 23:58:45 +08:00
* devices.in (dev_storage): Map /dev/clipboard to \Device\Null. * devices.cc: Regenerate. * fhandler.h (fhandler_dev_clipboard::open): Drop declaration. * fhandler_clipboard.cc (fhandler_dev_clipboard::dup): Drop call to open. Set private members to 0 and call fhandler_base::dup. (fhandler_dev_clipboard::open): Remove so that default fhandler_base::open is used to open \Device\Null. (set_clipboard): Drop gratuitios call to RegisterClipboardFormatW. (fhandler_dev_clipboard::close): Call fhandler_base::close from here.

- Allow to use advisory locking on any device which is backed by an OS handle.
Right now this excludes /dev/dsp as well as almost all virtual files under
/proc.
* devices.in (dev_storage): Map /dev/zero and /dev/full to \Device\Null. * devices.cc: Regenerate. * dtable.h (struct dtable): Make fhandler_base friend, rather than fhandler_disk_file. * fhandler.cc (fhandler_base::open_with_arch): Create unique id. (fhandler_base::cleanup): Call del_my_locks. (fhandler_base::fcntl): Handle F_GETLK, F_SETLK and F_SETLKW. * fhandler.h (fhandler_base::get_dev): Return real device number. (fhandler_base::set_unique_id): New inline method. (fhandler_disk_file::lock): Drop declaration. (fhandler_disk_file::get_dev): New method, return pc.fs_serial_number. (fhandler_dev_zero::open): Drop declaration. * fhandler_disk_file.cc (fhandler_disk_file::close): Move del_my_locks call to fhandler_base::open_with_arch. (fhandler_disk_file::fcntl): Move handling of locking commands to fhandler_base::fcntl. (fhandler_base::open_fs): Drop call to NtAllocateLocallyUniqueId. * fhandler_zero.cc (fhandler_dev_zero::open): Remove so that default fhandler_base::open is used to open \Device\Null. * flock.cc (fixup_lockf_after_exec): Finding a single fhandler is enough here. (fhandler_base::lock): Replace fhandler_disk_file::lock. Refuse to lock nohandle devices. Handle read/write test using POSIX flags. Explain why. Never fail on SEEK_CUR or SEEK_END, rather assume position 0, just as Linux. * net.cc (fdsock): Create unique id.

* sigproc.h (hold_everything::ischild): Declare as reference. (hold_everything::hold_everything): Store address of caller's notion of "ischild".

- 64 bit only: Correctly mmap'ing regions > 4 Gigs.
Fixes: http://cygwin.com/ml/cygwin/2013-09/msg00155.html
* fhandler_process.cc (format_process_ctty): Fix random content of /proc/$PID/ctty if the process has no controlling tty. Set to just "\n" instead.

- Properly set process sid rather than always using -1.
Fixes: http://cygwin.com/ml/cygwin/2013-10/threads.html#00237
* fhandler_clipboard.cc (fhandler_dev_clipboard::open): Drop gratuitios handling of membuffer. It's NULL anyway. (fhandler_dev_clipboard::lseek): Set membuffer to NULL after freeing it to avoid subsequent crashes when accessing invalid pointer.
2013-10-25 23:04:24 +08:00
- Fix a potential crash after calling lseek on /dev/clipboard.
