a kernel pointer.  This is something that works for most common sockopts
(and is something that the ePBF support relies on), but unfortunately
in various corner cases we either don't use the passed in length, or in
one case actually copy data back from setsockopt, so we unfortunately
can't just always do the copy in the highlevel code, which would have
been much nicer.

could you rebase on bpf-next tree and we can route it this way then?
we'll also test the whole thing before applying.

The bpf-next tree is missing all my previous setsockopt cleanups, so
there series won't apply.

Right. I've realized that after sending that email two days ago.
Now bpf-next->net-next PR is pending and as soon as it's merged
bpf-next will have all the recent bits.
