====================
pull-request: bpf 2018-09-24
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Several fixes for BPF sockmap to only allow sockets being attached in
ESTABLISHED state, from John.
2) Fix up the license to LGPL/BSD for the libc compat header which contains
fallback helpers that libbpf and bpftool is using, from Jakub.
