[dpdk-stable] patch 'net/ixgbe: fix hash handle leak' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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/c1723e2d14001ac5b7aa0227e4aef911b4e0e9dd

Thanks.

Subject: [PATCH] net/ixgbe: fix hash handle leak
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 03f83d6c5c9f9d30ef2cd7c2b0fe5d86935cd372 ]

In the ixgbe_fdir_filter_init and ixgbe_l2_tn_filter_init functions,
after the hash handle is created, the handle is not released in
subsequent abnormal branches.

Fixes: 080e3c0ee989 ("net/ixgbe: store flow director filter")
Fixes: d0c0c416ef1f ("net/ixgbe: store L2 tunnel filter")
