Merge branch 'Add new args into tcp_congestion_ops' cong_control'

Browse source

Miao Xu says:

====================
This patchset attempts to add two new arguments into the hookpoint
cong_control in tcp_congestion_ops. The new arguments are inherited
from the caller tcp_cong_control and can be used by any bpf cc prog
that implements its own logic inside this hookpoint.

Please review. Thanks a lot!

Changelog
=====
v2->v3:
  - Fixed the broken selftest caused by the new arguments.
  - Renamed the selftest file name and bpf prog name.

v1->v2:
  - Split the patchset into 3 separate patches.
  - Added highlights in the selftest prog.
  - Removed the dependency on bpf_tcp_helpers.h.
