nat64-bpf: Initial version This adds an initial version of a NAT64 translator in BPF. It compiles and loads, but doesn't actually appear to work yet. Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> 2021-09-29 01:46:09 +02:00			`# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause)`

nat64: Insert route and neighbour entry on setup/teardown We insert a v4-via-v6 route on the interface to direct packets to the v4 subnet to the right interface, where it will be rewritten by the BPF program. We also create a fake neighbour entry so the kernel won't do neighbour resolution when sending the pre-rewrite packet. The egress BPF program will use bpf_redirect_neigh() to do proper neighbour resolution for the actual destination after rewriting the packet.
