Subject: [dpdk-dev] [PATCH v3 5/5] net/tap: fix netlink socket file descriptor check before close
Date: Tue, 7 Apr 2020 12:23:34 +0800 [thread overview]
Message-ID: <1586233414-7644-1-git-send-email-wangyunjian@huawei.com> (raw)
From: Yunjian Wang <wangyunjian@huawei.com>
The "internals->nlsk_fd" is possibly a zero value. Error comparison
should check for negative fd.
Fixes: de96fe68ae95 ("net/tap: add basic flow API patterns and actions")
