[dpdk-stable] patch 'crypto/openssl: fix usage of non constant time memcmp' has been queued to LTS release 18.11.3

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 09/03/19. 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/76659ab156f8e758946c80184b6db2b3460953e0

Thanks.

Kevin Traynor

Subject: [PATCH] crypto/openssl: fix usage of non constant time memcmp

[ upstream commit a3f9fededfca6758abb751d67b11cda660a3399a ]

ANSI C memcmp is not constant time function per spec so it should
be avoided in cryptography usage.

Fixes: d61f70b4c918 ("crypto/libcrypto: add driver for OpenSSL library")
