ipv4 05/05: add sysctl to accept packets with local source addresses
commit 8ec1e0ebe26087bfc5c0394ada5feb5758014fc8 Author: Patrick McHardy <kaber@trash.net> Date: Thu Dec 3 12:16:35 2009 +0100 ipv4: add sysctl to accept packets with local source addresses Change fib_validate_source() to accept packets with a local source address when the "accept_local" sysctl is set for the incoming inet device. Combined with the previous patches, this allows to communicate between multiple local interfaces over the wire. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
