Masami Hiramatsu 55479f6475 kprobes: Allow probe on some kprobe functions ... There is no need to prohibit probing on the functions used for preparation, registeration, optimization, controll etc. Those are safely probed because those are not invoked from breakpoint/fault/debug handlers, there is no chance to cause recursive exceptions. Following functions are now removed from the kprobes blacklist: add_new_kprobe aggr_kprobe_disabled alloc_aggr_kprobe alloc_aggr_kprobe arm_all_kprobes __arm_kprobe arm_kprobe arm_kprobe_ftrace check_kprobe_address_safe collect_garbage_slots collect_garbage_slots collect_one_slot debugfs_kprobe_init __disable_kprobe disable_kprobe disarm_all_kprobes __disarm_kprobe disarm_kprobe disarm_kprobe_ftrace do_free_cleaned_kprobes do_optimize_kprobes do_unoptimize_kprobes enable_kprobe force_unoptimize_kprobe free_aggr_kprobe free_aggr_kprobe __free_insn_slot __get_insn_slot get_optimized_kprobe __get_valid_kprobe init_aggr_kprobe init_aggr_kprobe in_nokprobe_functions kick_kprobe_optimizer kill_kprobe kill_optimized_kprobe kprobe_addr kprobe_optimizer kprobe_queued kprobe_seq_next kprobe_seq_start kprobe_seq_stop kprobes_module_callback kprobes_open optimize_all_kprobes optimize_kprobe prepare_kprobe prepare_optimized_kprobe register_aggr_kprobe register_jprobe register_jprobes register_kprobe register_kprobes register_kretprobe register_kretprobe register_kretprobes register_kretprobes report_probe show_kprobe_addr try_to_optimize_kprobe unoptimize_all_kprobes unoptimize_kprobe unregister_jprobe unregister_jprobes unregister_kprobe __unregister_kprobe_bottom unregister_kprobes __unregister_kprobe_top unregister_kretprobe unregister_kretprobe unregister_kretprobes unregister_kretprobes wait_for_kprobe_optimizer I tested those functions by putting kprobes on all instructions in the functions with the bash script I sent to LKML.
