3.16.44-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Mantas M <[email protected]> commit c2ed1880fd61a998e3ce40254a99a2ad000f1a7d upstream. 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 <prefix> proto something`. Signed-off-by: Mantas Mikulėnas <[email protected]> Signed-off-by: David S.
