Konrad Rzeszutek Wilk 8f5a2856d9 xen/blkback: Check device permissions before allowing OP_DISCARD ... commit 604c499cbb upstream. We need to make sure that the device is not RO or that the request is not past the number of sectors we want to issue the DISCARD operation for. This fixes CVE-2013-2140.
