CVE: N/A

----------------------------------------------------

Some network acceleration solutions, such as sockmap, are valid only for
internal packets of the local host. The bpf_is_local_ipaddr() bpf helper
function is added so that the ebpf program can determine whether a packet
is an internal packet of the local host.
