Subject: [PATCH] net/af_xdp: fix resources leak when xsk configure fails
Date: Thu, 22 Feb 2024 11:07:42 +0800	[thread overview]
Message-ID: <1708571262-48380-1-git-send-email-wangyunjian@huawei.com> (raw)

In xdp_umem_configure() allocated some resources for the
xsk umem, we should delete them when xsk configure fails,
otherwise it will lead to resources leak.

Fixes: f1debd77efaf ("net/af_xdp: introduce AF_XDP PMD")
Cc: stable@dpdk.org
