Subject: [PATCH bpf-next v5 0/2] bpf: enable some functions in cgroup programs
From: Matteo Croce <teknoraver@...a.com>
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@...a.com>
Matteo Croce (2):
bpf: enable generic kfuncs for BPF_CGROUP_* programs
bpf: allow bpf_current_task_under_cgroup() with BPF_CGROUP_*
