This patchset addresses a few problems discovered when analyzing aborts of (an older version of) QEMU with backported commit afd9096eb1882f23929f5b5c177898ed231bac66 "virtio: error out if guest exceeds virtqueue size". Those problems are present in master, too, except that they don't trigger an abort and are thus not as easy to notice.
