+Description: The security information used on the process by
+ a Linux security module (LSM) active on the system
+ prior to the most recent exec() call.
+ The details of permissions required to read from
+ this interface is LSM dependent.
+ A process cannot write to this interface unless it
+ refers to itself.
+ The other details of permissions required to write to
+ this interface are LSM dependent.
+ The format of the data used by this interface is LSM
+ dependent.
+ SELinux and AppArmor provide this interface.
