[v2,bpf-next,0/3] bpftool: support loading flow dissector

Message

Stanislav Fomichev Nov. 7, 2018, 10:43 p.m. UTC

v2 changes:
* addressed comments/style issues from Jakub Kicinski & Quentin Monnet
* removed logic that populates jump table
* added cleanup for partial failure in bpf_object__pin

This patch series adds support for loading and attaching flow dissector
programs from the bpftool:

* first patch fixes flow dissector section name in the selftests (so
  libbpf auto-detection works)
* second patch adds proper cleanup to bpf_object__pin which is now being
  used to attach all flow dissector progs/maps
* third patch adds actual support to the bpftool

See third patch for the description/details.

Stanislav Fomichev (3):
  selftests/bpf: rename flow dissector section to flow_dissector
  libbpf: cleanup after partial failure in bpf_object__pin
  bpftool: support loading flow dissector
