316This value can be used to query and set the core dump mode for setuid
317or otherwise protected/tainted binaries. The modes are
318
3190 - (default) - traditional behaviour. Any process which has changed
320 privilege levels or is execute only will not be dumped
3211 - (debug) - all processes dump core when possible. The core dump is
322 owned by the current user and no security is applied. This is
323 intended for system debugging situations only. Ptrace is unchecked.
3242 - (suidsafe) - any binary which normally would not be dumped is dumped
325 readable by root only. This allows the end user to remove
326 such a dump but not access it directly. For security reasons
327 core dumps in this mode will not overwrite one another or
328 other files. This mode is appropriate when adminstrators are
329 attempting to debug problems in a normal environment.
