[PATCH net-next 0/6] BPF updates

[Daniel Borkmann <daniel@iogearbox.net>]

This set contains various updates for eBPF, i.e. the addition of a
generic csum helper function and other misc bits that mostly improve
existing helpers and ease programming with eBPF on cls_bpf. For more
details, please see individual patches.

Set is rebased on top of http://patchwork.ozlabs.org/patch/584465/.

Thanks!

  bpf: add new arg_type that allows for 0 sized stack buffer

  bpf: remove artificial bpf_skb_{load,store}_bytes buffer limitation
