From 2b5ec1a5f9738ee7bf8f5ec0526e75e00362c48f Mon Sep 17 00:00:00 2001 From: Ye Yin Date: Thu, 26 Oct 2017 16:57:05 +0800 Subject: netfilter/ipvs: clear ipvs_property flag when SKB net namespace changed When run ipvs in two different network namespace at the same host, and one ipvs transport network traffic to the other network namespace ipvs. 'ipvs_property' flag will make the second ipvs take no effect. So we should clear 'ipvs_property' when SKB network namespace changed.
