[dpdk-stable] patch 'crypto/openssl: fix free of asymmetric crypto keys' has been queued to LTS release 18.11.3

[Kevin Traynor]

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 09/04/19. 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/78807f9b4ffeec5593f7cdb8189cc58a776f369c

Thanks.

Kevin Traynor

Subject: [PATCH] crypto/openssl: fix free of asymmetric crypto keys

[ upstream commit 77411bd6387b28e91eac1702c872712f09c62c4b ]

In case big number need to be freed, data it contains should
also be cleared before especially if it is critical data like
private keys.

Fixes: 3e9d6bd447fb ("crypto/openssl: add RSA and mod asym operations")
