HAP-Linux is a collection of security related patches which are designed to be applied after Solar Designers Openwall patches are installed. Changes include some extra information in the printks, and the ability to allow hard links to files you don't own which are in your group, and the ability to follow links & pipes in +t directories if they are not world-writable. This is useful for getting various daemons to run chrooted as a non-root user, and some secure drop- directory stuff.

The Openwall Linux kernel patch is a collection of security "hardening" features for the Linux kernel which can stop most 'cookbook' buffer overflow exploits. The patch can also add more privacy to the system by restricting access to parts of /proc so that users may not see what others are doing. Also tightens down file descriptors 0, 1, and 2, implements process limits and shared memory destruction.
