At the same time, the legacy kprobe_event also have similar problems. With these patches, whenever an error is returned, it ensures that the created kprobe_event/uprobe_event is cleaned. V1 -> v3: - add detail commits - call remove_kprobe_event_legacy() on failed bpf_program__attach_perf_event_opts() v3 -> v4: - cleanup the legacy kprobe_event on failed add/attach_event ==================== Signed-off-by: Andrii Nakryiko --- e4adceef5b0e75f000754254047af59c65295ac4
