Re: [V2 PATCH net-next 0/2] Fixes for XDP_REDIRECT map

This my V2 of catching XDP_REDIRECT and bpf_redirect_map() API usage
that can potentially crash the kernel.  Addressed Daniels feedback in
patch01, and added patch02 which catch and cleanup dangling map
pointers.

I know John and Daniel are working on a more long-term solution, of
recording the bpf_prog pointer together with the map pointer.  I just
wanted to propose these fixes as a stop-gap to the potential crashes.

Jesper if these are still relevant, please resubmit against the 'net'
tree, thanks!
