patch 'hash: check name when creating a hash' has been queued to stable release 21.11.8

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/24. 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

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/8a77d04eb381a3096611f750700c776b6df88b18

Thanks.

Kevin

Subject: [PATCH] hash: check name when creating a hash

[ upstream commit 8f36e53317ecf8384461e4f692e46beaaf6c4d2f ]

Add NULL pointer check to params->name, which is later
copied into the hash datastructure. Without this check
the code segfaults on the strlcpy() of a NULL pointer.

Fixes: 48a399119619 ("hash: replace with cuckoo hash implementation")
