From fe29ec41aaa51902aebd63658dfb04fe6fea8be5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Linus=20L=C3=BCssing?= Date: Thu, 17 Feb 2011 08:17:52 +0000 Subject: [PATCH] bridge: Use IPv6 link-local address for multicast listener queries MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently the bridge multicast snooping feature periodically issues IPv6 general multicast listener queries to sense the absence of a listener. For this, it uses :: as its source address - however RFC 2710 requires: "To be valid, the Query message MUST come from a link-local IPv6 Source Address". Current Linux kernel versions seem to follow this requirement and ignore our bogus MLD queries. With this commit a link local address from the bridge interface is being used to issue the MLD query, resulting in other Linux devices which are multicast listeners in the network to respond with a MLD response (which was not the case before).
