Subject: [net-next v2] selftests: Fix the if conditions of in test_extra_filter()
Date: Fri, 23 Sep 2022 15:02:37 +0800	[thread overview]
Message-ID: <1663916557-10730-1-git-send-email-wangyufen@huawei.com> (raw)

The socket 2 bind the addr in use, bind should fail with EADDRINUSE. So
if bind success or errno != EADDRINUSE, testcase should be failed.
