From 3eadd3374c1b6c65759f147dd6f41e65c347c04b 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.
