From 8c338f84ea1597806ead6fa70dbacca9c726cb3f Mon Sep 17 00:00:00 2001 From: "kfraser@localhost.localdomain" Date: Fri, 12 Jan 2007 15:23:07 +0000 Subject: [LINUX] ipv6: Disable addrconf on Xen bridge device The ipv6-no-autoconf patch didn't disable IPv6 addrconf completely. This means that the Xen bridge device still interfered with normal IPv6 operation by engaging the IPv6 network with a bogus MAC address. For details please refer to https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200360 The following patch completely disables IPv6 on the Xen bridge device by temporarily setting the MTU to a value less than the minimum allowed for IPv6. Upstream will provide a cleaner way to disable IPv6 addrconf in future, possibly in the form of a proc sysctl. Of course if the Xen loopback device is removed it would render this change unnecessary.
