LKDTM Linux Kernel Dump Test Module

A kernel self-test facility that deliberately provokes crashes, memory-safety violations, and other faults on demand so developers can validate that kernel hardening, panic handling, and debugging infrastructure behave correctly. It is a testing tool, not a driver for any physical device.

recommendation

This is not actually a driver directory; it is the Linux Kernel Dump Test Module, a built-in fault-injection and crash-testing harness that kernel developers and security researchers use to deliberately trigger bugs, memory corruption, and protection violations to verify that kernel hardening features and crash-handling paths work correctly. It controls no hardware.

codex reasoning notes (technical)

Not a driver directory: LKDTM is the Linux Kernel Dump Test Module, a kernel fault-injection/test harness rather than hardware driver code.
