The Openwall Linux kernel patch is a collection of security "hardening" features for the Linux kernel. In addition to the new features, some versions of the patch contain various security fixes. The "hardening" features of the patch, while not a complete method of protection, provide an extra layer of security against the easier ways to exploit certain classes of vulnerabilities and/or reduce the impact of those vulnerabilities. The patch can also add a little bit more privacy to the system by restricting access to parts of /proc so that users may not see what others are doing.
