[Xen-devel] PATCH: Set close-on-exec flag for QEMU disks

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

QEMU does not currently set the close-on-exec flag after opening its virtual
disk images. This causes problems when it later runs the /etc/xen/qemu-ifup
script because the file descriptors get propagated to networking commands
like brctl / ifconfig. The SELinux policy quite rightly does not allow the
networking scripts to access the virtual disk images, so these inherited
file descriptors for AVC denials to be logged.

The attached patch modifies all the QEMU disk driver backends to make sure
the close-on-exec flag is turned on

  Signed-off-by: Daniel P. Berrange <berrange@xxxxxxxxxx>

Regards,
Dan.
