Subject: [dpdk-dev] [PATCH v1] net/pfe: fix to set mac_addrs to NULL after freeing
Date: Tue, 7 Apr 2020 19:39:11 +0800	[thread overview]
Message-ID: <1586259551-19324-1-git-send-email-wangyunjian@huawei.com> (raw)

From: Yunjian Wang <wangyunjian@huawei.com>

It does not correctly set the mac_addrs variable to NULL after
freeing it, which will lead to a double free.

Fixes: 67fc3ff97c39 ("net/pfe: introduce basic functions")
Cc: stable@dpdk.org
