LWN on the Patent Encumbrence of SELinux

Anonymous Coward writes "LWN has a story about patents in SELinux. The article says: "Much of the actual work in the implementation of SELinux was done by Secure Computing Corporation (SCC). SCC, in its implementation of SELinux, used a technology that it calls type enforcement. As it turns out, SCC has a patent on this technology." Sigh.
