This patchset addresses multiple overflows and signedness-related issues
in packet socket ring buffers.

Andrey Konovalov (5):
  net/packet: fix overflow in check for priv area size
  net/packet: add explicit checks for tp_frame_size
  net/packet: fix overflow in check for tp_frame_nr
  net/packet: fix overflow in check for tp_reserve
  net/packet: reorder checks for ring buffer parameters

These are a lot of changes to backport to stable kernels.

Can we separate the minimal patch set needed to address known overflow
to send to net (with annotation [PATCH net]) and follow up with the larger
cleanup to net-next.

Sure, I can put patches 2 and 5 to a separate patchset.
