    Point of clarification: The original SELinux prototype NSA released in
    Dec 2000 based on Linux 2.2.x kernels was a proof-of-concept reference
    implementation. I wouldn't describe the current implementation in
    mainline Linux 2.6 and certain distributions in the same manner. Also,
    the separate Q&A about "did you try to fix any vulnerabilities" is just
    saying that NSA did not perform a thorough code audit of the entire
    Linux kernel; we just implemented the extensions needed for mandatory
    access control. has some good pointers for SELinux
    resources. There is also a recently created SELinux news site at
