With progs.debug we can get the attached name of the bpf prog which is attached to a kernel function. But we can't get bpf progs which are attached to others, like a cgroup, sockmap and etc. This patchset means to extend the attached name to other types. The member attach_func_name in struct bpf_prog_aux is renamed to attach_name in patch #1, to avoid possible confusion. Then in patch #2 and #3 I extend the attached name to bpf progs which are attached to a cgroup or a sockmap. If this solution is acceptable, I will extend it to other attach types in the next step.
