From dedc87ed391902a54541c7198727268f24f22f05 Mon Sep 17 00:00:00 2001 From: Mantas M Date: Fri, 16 Dec 2016 10:30:59 +0200 Subject: [PATCH] net: ipv6: check route protocol when deleting routes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The protocol field is checked when deleting IPv4 routes, but ignored for IPv6, which causes problems with routing daemons accidentally deleting externally set routes (observed by multiple bird6 users). This can be verified using `ip -6 route del proto something`. Signed-off-by: Mantas Mikulėnas Signed-off-by: David S.
