[dpdk-stable] patch 'net/tap: fix file descriptor check' has been queued to LTS release 17.11.5

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/01/18. 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. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] net/tap: fix file descriptor check

[ upstream commit e0a10f4691c2fa74d228a1c21772456afef1e060 ]

Static analysis tools don't like the fact that fd could be zero
in the error path. This won't happen in real world because
stdin would have to be closed, then other error occurring.

Coverity issue: 14079
Fixes: 02f96a0a82d1 ("net/tap: add TUN/TAP device PMD")
