      ipv4: Add interface option to enable routing of 127.0.0.0/8 · d0daebc3
      Thomas Graf authored
      Routing of 127/8 is tradtionally forbidden, we consider
      packets from that address block martian when routing and do
      not process corresponding ARP requests.
      
      This is a sane default but renders a huge address space
      practically unuseable.
      
      The RFC states that no address within the 127/8 block should
      ever appear on any network anywhere but it does not forbid
      the use of such addresses outside of the loopback device in
      particular. For example to address a pool of virtual guests
      behind a load balancer.
      
      This patch adds a new interface option 'route_localnet'
      enabling routing of the 127/8 address block and processing
      of ARP requests on a specific interface.
      
      Note that for the feature to work, the default local route
      covering 127/8 dev lo needs to be removed.
      
      Example:
        $ sysctl -w net.ipv4.conf.eth0.route_localnet=1
        $ ip route del 127.0.0.0/8 dev lo table local
        $ ip addr add 127.1.0.1/16 dev eth0
        $ ip route flush cache
      
      V2: Fix invalid check to auto flush cache (thanks davem)
