Subject: [dpdk-dev] [PATCH] net/vhost: fix double free of MAC addrs
Date: Wed, 19 Dec 2018 13:37:18 +0900	[thread overview]
Message-ID: <201812190440.wBJ4cabt027283@ccmail04.silk.ntt-tx.co.jp> (raw)

The common data freeing has been moved to rte_eth_dev_release_port(),
so freeing mac_addrs like this in eth_dev_close() is unnecessary and
will cause double free.

Fixes: e16adf08e54d ("ethdev: free all common data when releasing port")
Cc: stable@dpdk.org
