From c2ed1880fd61a998e3ce40254a99a2ad000f1a7d 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.
