Subject: [dpdk-dev]  [PATCH] efd: fix tailq entry leak in error path
Date: Tue, 29 Sep 2020 11:31:35 +0800	[thread overview]
Message-ID: <49d4bdc58b81564788cfd31f16ef2e66c1673f6d.1601347917.git.wangyunjian@huawei.com> (raw)

From: Yunjian Wang <wangyunjian@huawei.com>

In rte_efd_create() allocated memory for tailq entry, we should
free it when error happens, otherwise it will lead to memory leak.

Fixes: 56b6ef874f80 ("efd: new Elastic Flow Distributor library")
Cc: stable@dpdk.org
