[dpdk-stable] patch 'net/virtio: fix dangling pointer on failure' has been queued to LTS release 18.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/13/19. 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/9960f97eba5b60118b7e2f7c17117fbf4a28730f

Thanks.

Kevin Traynor

Subject: [PATCH] net/virtio: fix dangling pointer on failure

[ upstream commit 7dee8c79483e370a346d68060b0b890b273e9a46 ]

When eth_virtio_dev_init() is cleaning up, it does not correctly set
the mac_addrs variable to NULL, which will lead to a double free.

Found during unit-test fixes.

Fixes: 43d18765c027 ("net/virtio: fix memory leak on failure")
