Message-ID: <20180423065927.23127-1-jolsa@kernel.org> (raw)

hi,
sending the change to store and dump the license
info for loaded BPF programs. It's important for
us get the license info, when investigating on
screwed up machine.

Adding change to bpftool to dump the license via:

  # bpftool prog list
  1: kprobe  name func_begin  tag 59bef35a42fda602 license GPL
          loaded_at Apr 22/15:46  uid 0
          xlated 272B  not jited  memlock 4096B  map_ids 1

  # bpftool prog show --json
  [{"id":1,"type":"kprobe","name":"fun ... ,"license":"GPL", ... ]

Also available at:
  https://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  bpf/license

thanks,
jirka
