ScopedPrSetPtracer()

crashpad::ScopedPrSetPtracer::ScopedPrSetPtracer	(	pid_t	pid,
		bool	may_log )

Uses PR_SET_PTRACER to set pid as the caller's ptracer.

PR_SET_PTRACER is only supported if the Yama Linux security module (LSM) is enabled. Otherwise, prctl(PR_SET_PTRACER, ...) fails with EINVAL. See linux-4.9.20/security/yama/yama_lsm.c yama_task_prctl() and linux-4.9.20/kernel/sys.c [sys_]prctl().

An error message will be logged on failure only if may_log is true and prctl does not fail with EINVAL;

Parameters

[in]	pid	The process ID of the process to make the caller's ptracer.
[in]	may_log	if true, this class may log error messages.
