[Qemu-devel] [PATCH 0/3] virtio/vhost: Add checks for uninitialized VQs

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

Hi folks,

This series adds a virtio_queue_valid() for use by virtio-pci code in
order to prevent opreations upon uninitialized VQs, that is currently
expected to occur during seabios setup of virtio-scsi.

This also includes a vhost specific check for uninitialized VQs in
vhost_verify_ring_mappings() to avoid this same case.

Please review.

  virtio: add API to check that ring is setup

  virtio-pci: Add virtio_queue_valid checks ahead of
    virtio_queue_get_num
  vhost: Check+skip uninitialized VQs in vhost_verify_ring_mappings
