Hi David,

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Sanitize attr->{prog,map}_type from bpf(2) since used as an array index
   to retrieve prog/map specific ops such that we prevent potential out of
   bounds value under speculation, from Mark and Daniel.

Please consider pulling these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git

Thanks a lot!
