From 1ba8d77f410d3b7423df39e8a10a02af272d3c42 Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Thu, 4 Aug 2016 12:11:57 +0200 Subject: [PATCH] sctp_diag: Respect ss adding TCPF_CLOSE to idiag_states Since 'ss' always adds TCPF_CLOSE to idiag_states flags, sctp_diag can't rely upon TCPF_LISTEN flag solely being present when listening sockets are requested.
