Title:
  radvd running as neutron user in Kilo, attached network dead

Status in App Catalog:
  Confirmed
Status in OpenStack Neutron (virtual network service):
  Fix Committed
Status in neutron kilo series:
  Fix Released

Bug description:
  Kilo RC1 release, mirantis Debian Jessie build

  Linux Kernel 3.19.3, ML2 vlan networking

  radvd version 1:1.9.1-1.3

  Network with IPv6 ULA SLAAC, IPv6 GUA SLAAC, Ipv4 RFC1918 configured.

  Radvd does not start, neutron-l3-agent does not set up OVS vlan
  forwarding between network and compute node, IPv4 completely
  disconnected as well. Looks like complete L2 breakage.

  Need to get this one fixed before release of Kilo.

  Work around:

  chown root:neutron /usr/sbin/radvd
  chmod 2750 /usr/sbin/radvd

  radvd gives message about not being able to create an IPv6 ICMP port
  in neutron-l3-agent log, just like when run as an non-root user.

  Notice radvd is not being executed via root wrap/sudo anymore, like
  all the other ip route/ip address/ip netns information gathering
  commands. Was executing in a privileged fashion missed in Neutron code
  refactor?
