Introduction

What is paxtest
paxtest is:
PaX is a Linux kernel patch which adds much stricter control on how memory is being used by applications. A normal Linux kernel leaves the control to the application and does not implement any enforcement. Especially buffer overflow attacks benefit from the absence of kernel enforced memory control. PaX tries to do its best to enforce this control of memory used by applications, thereby making it harder to successfully exploit buffer overflows.
Paxtest provides a regression test suite that covers most (but not all) of PaX functionality. It can also be used to test other memory protection patches.
