Subject: [dpdk-dev] [PATCH v2] net/pfe: fix double free of MAC address
Date: Thu, 9 Apr 2020 09:59:00 +0800 [thread overview]
Message-ID: <1586397540-19668-1-git-send-email-wangyunjian@huawei.com> (raw)
From: Yunjian Wang <wangyunjian@huawei.com>
The 'mac_addrs' freeing has been moved to rte_eth_dev_release_port(),
so freeing 'mac_addrs' like this in pfe_eth_exit() is unnecessary and
will cause double free.
Fixes: 67fc3ff97c39 ("net/pfe: introduce basic functions")
CC: stable@dpdk.org
