Yes, we need cap_sys_admin only to load bpf:
tc filter add dev eth0 ingress matchall action bpf obj ./tc_test_kern.o sec test
I'm not sure to understand why cap_net_admin is not enough to run the previous
command (ie why load is forbidden).
I want to avoid sys_admin, thus cap_bpf will be ok. But we need to manage the
backward compatibility.
