Michael S. Tsirkin 7931825da8 vfio: fix ioctl error handling ... commit 8160c4e455820d5008a1116d2dca35f0363bb062 upstream. 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. Signed-off-by: Michael S.
