libfiu is a C library for fault injection. It provides functions to mark "points of failure" inside your code (the "core API"), and functions to enable/disable the failure of those points (the "control API"). The core API is used inside the code on which you want to perform failure injection. The control API is used inside the testing code in order to control the injection of failures.
KEDR is a framework to facilitate dynamic analysis of kernel modules in Linux ("KEDR" is an acronym for "KErnel-mode Drivers in Runtime"). KEDR allows you to intercept the calls that a kernel module makes to the functions exported by other modules and by the kernel proper. The tools provided by the framework can record the arguments and return values of these functions to a trace, perform fault simulation according to user-defined scenarios, and check the kernel modules for memory leaks and some other kinds of problems. Custom data collection and analysis tools for the Linux kernel can also be built on top of KEDR framework.
