Michael S. Tsirkin 1590808b43 vfio: fix ioctl error handling ... [ Upstream commit 8160c4e455 ] Calling return copy_to_user(...) in an ioctl will not do the right thing if there's a pagefault: copy_to_user returns the number of bytes not copied in this case. Fix up vfio to do return copy_to_user(...)) ? -EFAULT : 0; everywhere. Cc: stable@vger.kernel.org Signed-off-by: Michael S.
