Date: Thu, 31 Oct 2019 16:24:36 -0700 From: Wei Wang <weiwan@...gle.com> To: David Miller <davem@...emloft.net>, netdev@...r.kernel.org Cc: Wei Wang <weiwan@...gle.com>, "Maciej Żenczykowski" <maze@...gle.com>, Eric Dumazet <edumazet@...gle.com>, Craig Gallek <cgallek@...gle.com> Subject: [PATCH net] selftests: net: reuseport_dualstack: fix uninitalized parameter This test reports EINVAL for getsockopt(SOL_SOCKET, SO_DOMAIN) occasionally due to the uninitialized length parameter. Initialize it to fix this, and also use int for "test_family" to comply with the API standard.
