   250	=   ==========  ===============================================================
   251	0   (default)	Traditional behaviour. Any process which has changed
   252			privilege levels or is execute only will not be dumped.
   253	1   (debug)	All processes dump core when possible. The core dump is
   254			owned by the current user and no security is applied. This is
   255			intended for system debugging situations only.
   256			Ptrace is unchecked.
   257			This is insecure as it allows regular users to examine the
   258			memory contents of privileged processes.
   259	2   (suidsafe)	Any binary which normally would not be dumped is dumped
 > 260			anyway, but only if the ``core_pattern`` kernel sysctl (see
   261			:ref:`Documentation/admin-guide/sysctl/kernel.rst <core_pattern>`)
   262			is set to
   263			either a pipe handler or a fully qualified path. (For more
   264			details on this limitation, see CVE-2006-2451.) This mode is
   265			appropriate when administrators are attempting to debug
   266			problems in a normal environment, and either have a core dump
   267			pipe handler that knows to treat privileged core dumps with
   268			care, or specific directory defined for catching core dumps.
   269			If a core dump happens without a pipe handler or fully
   270			qualified path, a message will be emitted to syslog warning
   271			about the lack of a correct setting.
