From 9036b2fe092a107856edd1a3bad48b83f2b45000 Mon Sep 17 00:00:00 2001 From: Francesco Ruggeri Date: Fri, 1 Mar 2019 15:31:03 -0800 Subject: net: ipv6: add socket option IPV6_ROUTER_ALERT_ISOLATE By default IPv6 socket with IPV6_ROUTER_ALERT socket option set will receive all IPv6 RA packets from all namespaces. IPV6_ROUTER_ALERT_ISOLATE socket option restricts packets received by the socket to be only from the socket's namespace.
