SELinux runtime shared libraries

This package provides the shared libraries for Security-enhanced Linux that provides interfaces (e.g. library functions for the SELinux kernel APIs like getcon(), other support functions like getseuserbyname()) to SELinux-aware applications. Security-enhanced Linux is a patch of the Linux kernel and a number of utilities with enhanced security functionality designed to add mandatory access controls to Linux. The Security-enhanced Linux kernel contains new architectural components originally developed to improve the security of the Flask operating system. These architectural components provide general support for the enforcement of many kinds of mandatory access control policies, including those based on the concepts of Type Enforcement, Role-based Access Control, and Multi-level Security.

libselinux1 provides an API for SELinux applications to get and set process and file security contexts and to obtain security policy decisions. Required for any applications that use the SELinux API. libselinux may use the shared libsepol to manipulate the binary policy if necessary (e.g. to downgrade the policy format to an older version supported by the kernel) when loading policy.
