From f9d882ea5705cf03f547e75ac515f1457c89f526 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Sun, 7 Jan 2018 12:45:10 +0200 Subject: [PATCH] ipv6: Report dead flag during route dump Up until now the RTNH_F_DEAD flag was only reported in route dump when the 'ignore_routes_with_linkdown' sysctl was set. This is expected as dead routes were flushed otherwise. The reliance on this sysctl is going to be removed, so we need to report the flag regardless of the sysctl's value.
