Kees Cook 3e2a4c183a test: check copy_to/from_user boundary validation To help avoid an architecture failing to correctly check kernel/user boundaries when handling copy_to_user, copy_from_user, put_user, or get_user, perform some simple tests and fail to load if any of them behave unexpectedly. Specifically, this is to make sure there is a way to notice if things like what was fixed in commit `8404663f81` ("ARM: 7527/1: uaccess: explicitly check __user pointer when !CPU_USE_DOMAINS") ever regresses again, for any architecture. Additionally, adds new "user" selftest target, which loads this module.

Linux Kernel Selftests

The kernel contains a set of "self tests" under the tools/testing/selftests/
directory. These are intended to be small unit tests to exercise individual
code paths in the kernel.

Running the selftests
=====================

To build the tests:

  $ make -C tools/testing/selftests


To run the tests:

  $ make -C tools/testing/selftests run_tests

- note that some tests will require root privileges.


To run only tests targetted for a single subsystem:

  $  make -C tools/testing/selftests TARGETS=cpu-hotplug run_tests

See the top-level tools/testing/selftests/Makefile for the list of all possible
targets.


Contributing new tests
======================

In general, the rules for for selftests are

 * Do as much as you can if you're not root;

 * Don't take too long;

 * Don't break the build on any architecture, and

 * Don't cause the top-level "make run_tests" to fail if your feature is
   unconfigured.
