Correct some missing endian conversions of IPv4 addresses
The INADDR_LOOPBACK constant is in host endianness, and similarly the IN_MULTICAST macro expects a host endian address. However, there are some places in passt where we use those with network endian values. This means that passt will incorrectly allow you to set 127.0.0.1 or a multicast address as the guest address or DNS forwarding address. Add the necessary conversions to correct this. INADDR_ANY and INADDR_BROADCAST logically behave the same way, although because they're palindromes it doesn't have an effect in practice. Change them to be logically correct while we're there, though. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
