[PATCH bpf-next v5 0/2] bpf: enable some functions in cgroup programs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Matteo Croce <teknoraver@xxxxxxxx>

Enable some BPF kfuncs and the helper bpf_current_task_under_cgroup()
for program types BPF_CGROUP_*.
These will be used by systemd-networkd:
https://github.com/systemd/systemd/pull/32212

v4->v5:
Same code, but v4 had an old cover letter

v3->v4:
Reset all the acked-by tags because the code changed a bit.

Signed-off-by: Matteo Croce <teknoraver@xxxxxxxx>

Matteo Croce (2):
  bpf: enable generic kfuncs for BPF_CGROUP_* programs
  bpf: allow bpf_current_task_under_cgroup() with BPF_CGROUP_*
