Date: Mon, 1 Aug 2016 19:36:07 -0700 From: Jarno Rajahalme <jarno@....org> To: netdev@...r.kernel.org Cc: jarno@....org Subject: [PATCH net] openvswitch: Remove incorrect WARN_ONCE(). ovs_ct_find_existing() issues a warning if an existing conntrack entry classified as IP_CT_NEW is found, with the premise that this should not happen. However, a newly confirmed, non-expected conntrack entry remains IP_CT_NEW as long as no reply direction traffic is seen. This has resulted into somewhat confusing kernel log messages. This patch removes this check and warning. Fixes: 289f2253 ("openvswitch: Find existing conntrack entry after upcall.")
