Subject: [dpdk-dev] [PATCH v1] net/octeontx: fix dangling pointer on failure
Date: Tue, 7 Apr 2020 19:35:43 +0800
Message-ID: <1586259343-6272-1-git-send-email-wangyunjian@huawei.com> (raw)

From: Yunjian Wang <wangyunjian@huawei.com>

When octeontx_create() is cleaning up, it does not correctly set
the mac_addrs variable to NULL, which will lead to a double free.

Fixes: 9e399b88ce2f ("net/octeontx: fix memory leak of MAC address table")
CC: stable@dpdk.org
