From: Matteo Croce <teknora...@meta.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
v5->v6: Called register_btf_kfunc_id_set() only once Fixed build error with !CONFIG_CGROUPS 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 <teknora...@meta.com> Matteo Croce (2): bpf: enable generic kfuncs for BPF_CGROUP_* programs bpf: allow bpf_current_task_under_cgroup() with BPF_CGROUP_* include/linux/bpf.h | 1 + kernel/bpf/btf.c | 8 ++++++-- kernel/bpf/cgroup.c | 2 ++ kernel/bpf/helpers.c | 24 ++++++++++++++++++++++++ kernel/trace/bpf_trace.c | 27 ++------------------------- 5 files changed, 35 insertions(+), 27 deletions(-) -- 2.46.0
