Subject: [bpf-next PATCH v3 0/2] bpftool support for sockmap use cases

The first patch adds support for attaching programs to maps. This is
needed to support sock{map|hash} use from bpftool. Currently, I carry
around custom code to do this so doing it using standard bpftool will
be great.

The second patch adds a compat mode to ignore non-zero entries in
the map def. This allows using bpftool with maps that have a extra
fields that the user knows can be ignored. This is needed to work
correctly with maps being loaded by other tools or directly via
syscalls.

v3: add bash completion and doc updates for --mapcompat

John Fastabend (2):
      bpf: bpftool, add support for attaching programs to maps
      bpf: bpftool, add flag to allow non-compat map definitions
