Subject: [dpdk-stable] patch 'ethdev: fix secondary process memory overwrite' has been queued to LTS release 18.11.7
Date: Fri, 14 Feb 2020 17:03:01 +0000	[thread overview]
Message-ID: <20200214170337.25093-7-ktraynor@redhat.com> (raw)
In-Reply-To: <20200214170337.25093-1-ktraynor@redhat.com>

Hi,

FYI, your patch has been queued to LTS release 18.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/20/20. 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/ab4272aefa97c8a92fc07fe8e653b979a99e46d1

Thanks.

Kevin.

Subject: [PATCH] ethdev: fix secondary process memory overwrite

[ upstream commit 99ef90317da69a5e6ecc831ad05c6d2053e2b065 ]

Avoid overwriting device flags and other information in device
data stored in shared memory when a secondary process
probes PCI device.

Fixes: 494adb7f63f2 ("ethdev: add device fields from PCI layer")
