[dpdk-stable] patch 'crypto/zuc: fix build with GCC 11' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/6156da10414a4f7e60f262ba80dd8b5bf9cccfd3

Thanks.

Subject: [PATCH] crypto/zuc: fix build with GCC 11
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 099db3d156038b792d97c29a6e2743369d7d50a5 ]

GCC 11 complains that some arrays may be uninitialized in
process_zuc_hash_op(). This is because their initialization
depends on num_ops being > 0.

This function is only called with num_ops > 0 because of
checks in process_zuc_hash_op().

To remove the warning initialize the arrays.

Fixes: 0b133c36ad7d ("crypto/zuc: support IPsec Multi-buffer lib v0.54")
