      ====================
      pull-request: bpf-next 2018-04-21
      
      The following pull-request contains BPF updates for your *net-next* tree.
      
      The main changes are:
      
      1) Initial work on BPF Type Format (BTF) is added, which is a meta
         data format which describes the data types of BPF programs / maps.
         BTF has its roots from CTF (Compact C-Type format) with a number
         of changes to it. First use case is to provide a generic pretty
         print capability for BPF maps inspection, later work will also
         add BTF to bpftool. pahole support to convert dwarf to BTF will
         be upstreamed as well (https://github.com/iamkafai/pahole/tree/btf),
         from Martin.
      
      2) Add a new xdp_bpf_adjust_tail() BPF helper for XDP that allows
         for changing the data_end pointer. Only shrinking is currently
         supported which helps for crafting ICMP control messages. Minor
         changes in drivers have been added where needed so they recalc
         the packet's length also when data_end was adjusted, from Nikita.
      
      3) Improve bpftool to make it easier to feed hex bytes via cmdline
         for map operations, from Quentin.
      
      4) Add support for various missing BPF prog types and attach types
         that have been added to kernel recently but neither to bpftool
         nor libbpf yet. Doc and bash completion updates have been added
         as well for bpftool, from Andrey.
      
      5) Proper fix for avoiding to leak info stored in frame data on page
         reuse for the two bpf_xdp_adjust_{head,meta} helpers by disallowing
         to move the pointers into struct xdp_frame area, from Jesper.
      
      6) Follow-up compile fix from BTF in order to include stdbool.h in
         libbpf, from Björn.
      
      7) Few fixes in BPF sample code, that is, a typo on the netdevice
         in a comment and fixup proper dump of XDP action code in the
         tracepoint exception, from Wang and Jesper.
