[dpdk-stable] patch 'crypto/qat: fix null auth when using VFIO' has been queued to LTS release 18.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/10/19. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/ac0a49ed92588f961b1f5e659d27c70f078eea13

Thanks.

Kevin.

Subject: [PATCH] crypto/qat: fix null auth when using VFIO

[ upstream commit 65beb9abca6dbb2167a53ab31d79e03f0857357b ]

When running auth NULL cases while using
vfio_pci, DMAR read/write faults appear. It
happens even if digest_length is set to 0.
This is caused by auth_res_addr initialized
as 0x0.

Fixes: 4e0955bddb08 ("crypto/qat: fix null auth algo overwrite")
