Subject: [dpdk-stable] patch 'vhost: prevent zero-copy with incompatible client mode' has been queued to LTS release 18.11.9
Date: Fri,  5 Jun 2020 19:24:09 +0100
Message-ID: <20200605182525.22483-12-ktraynor@redhat.com> (raw)
In-Reply-To: <20200605182525.22483-1-ktraynor@redhat.com>

Hi,

FYI, your patch has been queued to LTS release 18.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/10/20. 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/06b2fe9781c3cb251b2ac4255f2578636ace2b54

Thanks.

Kevin.

Subject: [PATCH] vhost: prevent zero-copy with incompatible client mode

[ upstream commit 715070ea10e6da1169deef2a3ea77ae934b4c333 ]

In server mode, virtio-user inits under the assumption that vhost-user
supports a list of features. However, this could be problematic when
in_order feature is negotiated but not supported by vhost-user when
enables dequeue_zero_copy later.

Add handling when vhost-user enables dequeue_zero_copy as client.

Fixes: 64ab701c3d1e ("vhost: add vhost-user client mode")
