Description: The current security information used by a Linux
security module (LSM) that is active on the system.
The details of permissions required to read from
this interface and hence obtain the security state
of the task identified 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 and hence change the security state of
the task identified are LSM dependent.
The format of the data used by this interface is LSM
dependent.
SELinux, Smack and AppArmor provide this interface.
Users: SELinux user-space
Smack user-space
AppArmor user-space
