  The series aims at improving virtqueue metadata pointers
dereferencing robust.

First patch fixes a real issue reported by our QE.

Five next patches validates queue index passed as input
of the Vhost API. They are split in 5 patches to ease
backporting to LTSes.

Last patch is not mandatory now that patch 1 ensures there
won't be holes in the array of virtqueue metadata pointers,
but I think it is a nice to have anyway.

Maxime Coquelin (7):
  vhost: fix virtqueues metadata allocation
  vhost: validate index in available entries API
  vhost: validate index in guest notification API
  vhost: validate index in live-migration API
  vhost: validate index in inflight API
  vhost: validate index in async API
  vhost: check virtqueue metadata pointer
