From 84b799a292ebc03de388f8573a169de6eb12c340 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Mon, 4 Feb 2019 13:44:47 +0100 Subject: net/smc: correct state change for peer closing If some kind of closing is received from the peer while still in state SMC_INIT, it means the peer has had an active connection and closed the socket quickly before listen_work finished. This should not result in a shortcut from state SMC_INIT to state SMC_CLOSED. This patch adds the socket to the accept queue in state SMC_APPCLOSEWAIT1. The socket reaches state SMC_CLOSED once being accepted and closed with smc_release(). Signed-off-by: Ursula Braun Signed-off-by: David S.
