[dpdk-stable] patch 'net/tap: fix file close on remove' has been queued to LTS release 18.11.9

[Kevin Traynor]

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 06/03/20. 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/15b5f477f3178079673afe4ed34719b0096d15ab

Thanks.

Kevin.

Subject: [PATCH] net/tap: fix file close on remove

[ upstream commit f9d5da4ab686b331c55bb98f43237d64ab820d0b ]

The internal structure is freed and set to NULL in the
rte_eth_dev_release_port() and zero is a valid fd. Ultimately
leads to a valid fd was closed by mistake.

Fixes: 3101191c63ab ("net/tap: fix device removal when no queue exist")
