[PATCH V5 0/4] Validate used buffer length

[Jason Wang]

Hi All:

This patch tries to validate the used buffer length in the virtio
core. This help to eliminate the unexpected result caused by buggy or
mailicous devices. For the drivers that can do the validation itself,
they can ask the virtio core to suppress the check.

Changes since V4:

- Fix the out of date description in the commit log

Changes since V3:

- Initialize the buflen to zero when the validation is done by the
  driver.

Jason Wang (4):
  virtio_ring: validate used buffer length
  virtio-net: don't let virtio core to validate used length
  virtio-blk: don't let virtio core to validate used length
  virtio-scsi: don't let virtio core to validate used buffer length
