[dpdk-stable] patch 'event/opdl: replace sprintf with snprintf' has been queued to LTS release 18.11.2

[Kevin Traynor <ktraynor@redhat.com>]

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 04/24/19. 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.

Thanks.

Kevin Traynor

Subject: [PATCH] event/opdl: replace sprintf with snprintf

[ upstream commit 57362ddf4262d0440ae1bddc6eaf69e9f94f9c85 ]

sprintf function is not secure as it doesn't check the length of string.
More secure function snprintf is used.

Fixes: 3c7f3dcfb0 ("event/opdl: add PMD main body and helper function")
