Because netlink is an IPC mechanism, you must bind with nl_pid 0 to make sure
you are talking to the kernel. The kernel code should only interpret packets
that have nl_pid set to 0. Any other packets should be discarded perhaps with
an error to make sure there's no impostors.
I agree for sending or connecting (destination pid), but for binding,
it's effectively a no-op, same as implicit bind that happens with plain
old sendmsg.

David is building a new kernel for everyone, I'll re-test when its available.
Nice, thanks.
