Subject: [dpdk-dev] [PATCH 0/7] vhost: make VQ metadata dereferencing robust
Date: Mon, 19 Oct 2020 19:34:08 +0200
Message-ID: <20201019173415.582407-1-maxime.coquelin@redhat.com> (raw)

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
