From: Ido Schimmel Date: Sun, 7 Jan 2018 10:45:10 +0000 (+0200) Subject: ipv6: Report dead flag during route dump X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f9d882ea5705cf03f547e75ac515f1457c89f526;p=linux.git 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.
