Subject: [PATCH v1 0/6] Harden a few virtio bits

Hi,

Here are 6 patches that harden console, net and 9p drivers against
various malicious host input as well as close a bounds check bypass
in the split virtio ring.

Changes since previous version:
 * Added Christian's R-B to 3/6
 * Added a speculation fix per Michael's comment on the cover letter
 * CC'ing lkml

Alexander Shishkin (3):
  virtio console: Harden control message handling
  virtio_net: Guard against buffer length overflow in
    xdp_linearize_page()
  virtio_ring: Prevent bounds check bypass on descriptor index

Andi Kleen (3):
  virtio console: Harden multiport against invalid host input
  virtio console: Harden port adding
  virtio 9p: Fix an overflow
