SELinux and Security Changes in the 2.6.27 Kernel

LinuxSecurity.com: This patch by Stephen Smalley addresses the case where "alien" SELinux security labels need to be written to the local filesystem, for example, in the case of building RPMs where the local policy is different to the policy on the system where the RPM is to be installed. This will help with enabling SELinux on build systems (e.g. in the Fedora infrastructure) and more generally with packagers and ISVs shipping third party policy with RPMS. In the recently released 2.6.27 kernel there are some functional changes in security particularly in SELinux. This article looks at those changes.
