Hi,

Yes, I'm late with this, sorry about that. I've mostly restricted this
to the most necessary fixes, though the virt_wifi one isn't but since
that's not used a lot, it's harmless and included since it's obvious.
This updated version includes another netlink buffer overrun fix, as
reported by syzbot.

The only thing that's bigger is the rfkill thing, but that's just since
it adds a new version of the struct for userspace to use, since the
change to the existing struct caused various breakage all around.

Please pull and let me know if there's any problem.

Thanks,
johannes
