[dpdk-stable] patch 'net/ena: fix crash with unsupported device argument' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/967dcfb168c8e8d79df4e5855b27cd66b68cc0f2

Thanks.

Subject: [PATCH] net/ena: fix crash with unsupported device argument
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 9f220a959d4d7208491efea8ca8e0c4a96b98f0e ]

As the documentation of rte_kvargs_parse() states, the valid_keys
argument must be NULL terminated. Lack of this feature may cause
segmentation fault if the passed devarg will be different then the
supported value.

Fixes: 8a7a73f26cc9 ("net/ena: support large LLQ headers")
