As I read through LWN today, I noted the following comment, http://lwn.net/Articles/255832/ :
Personally, I think it's absolutely essential to be able to build a kernel with dynamic LSM. Whether we like it or not, people do want to add in runtime loadable security modules for things like virus scanners, and until upstream offers these folks a viable alternative to LSM...well, they'll use it. Which reminded me of the TuxGuardian LSM[1] - another of the real-world uses to meet Linus's criteria? ("had examples of their real-world use to step forward and explain their use") In this specific project, LSM is used to collect up calls to bind() and connect() and pass them to userspace, e.g. do it ZoneAlarm-style and display a dialog window. Its codebase is probably not too up-to-date (website says last change last April - but I guess that's a no-brainer to update it).
