Subject: [dpdk-dev] [PATCH] net/af_xdp: fix memzone leak in error path
Date: Fri, 1 Dec 2023 16:03:07 +0800 [thread overview]
Message-ID: <64117415a68e8c920efdf905f799b26dcbc3f8fb.1701415014.git.wangyunjian@huawei.com> (raw)
In xdp_umem_configure() allocated memzone for the 'umem', we should
free it when xsk_umem__create() call fails, otherwise it will lead
to memory zone leak.
Fixes: f1debd77efaf ("net/af_xdp: introduce AF_XDP PMD")
