Otherwise, attaching with bpftool doesn't work with strict section names.
Also:
- Add --legacy option to switch back to pre-1.0 behavior
- Print a warning when program fails to load in strict mode to
point to --legacy flag
- By default, don't append / to the section name; in strict
mode it's relevant only for a small subset of prog types
+ bpftool --legacy prog loadall tools/testing/selftests/bpf/test_cgroup_link.o /sys/fs/bpf/kprobe type kprobe
libbpf: failed to pin program: File exists
Error: failed to pin all programs
+ bpftool prog loadall tools/testing/selftests/bpf/test_cgroup_link.o /sys/fs/bpf/kprobe type kprobe
v1 -> v2:
- strict by default (Quentin Monnet)
- add more info to --legacy description (Quentin Monnet)
- add bash completion (Quentin Monnet)
