Commit Message

The modules are being moved from lib/livepatch to
tools/testing/selftests/livepatch/test_modules.

This code moving will allow writing more complex tests, like for example an
userspace C code that will call a livepatched kernel function.

The modules are now built as out-of-tree
modules, but being part of the kernel source means they will be maintained.

Another advantage of the code moving is to be able to easily change,
debug and rebuild the tests by running make on the selftests/livepatch
directory, which is not currently possible since the modules on
lib/livepatch are build and installed using the "modules" target.

The current approach also keeps the ability to execute the tests manually
by executing the scripts inside selftests/livepatch directory, as it's
currently supported. If the modules are modified, they needed to be
rebuilt before running the scripts though.

The modules are built before running the selftests when using the
kselftest invocations:

	make kselftest TARGETS=livepatch
or
	make -C tools/testing/selftests/livepatch run_tests

Having the modules being built as out-of-modules requires changing the
currently used 'modprobe' by 'insmod' and adapt the test scripts that
check for the kernel message buffer.

Now it is possible to only compile the modules by running:

	make -C tools/testing/selftests/livepatch/

This way the test modules and other test program can be built in order
to be packaged if so desired.

As there aren't any modules being built on lib/livepatch, remove the
TEST_LIVEPATCH Kconfig and it's references.

Note: "make gen_tar" packages the pre-built binaries into the tarball.
       It means that it will store the test modules pre-built for
       the kernel running on the build host.

       Note that these modules need not binary compatible with
       the kernel built from the same sources. But the same
       is true for other packaged selftest binaries.

       The entire kernel sources are needed for rebuilding
       the selftests on another system.

Please, correct me if I am wrong, but with this change one would
require a configured build environment and kernel tree that matches
running kernel in order to run tests. Is that correct?

Thanks!

You don't need a kernel tree in order to run the tests, you can build
the modules and use gen_tar to pack them, setting KDIR to the currently
built kernel:
		make KDIR=$(pwd) TARGETS=livepatch -C
tools/testing/selftests

This can be used when packaging the tests, like Joe showed when
reviewing the v4:

	mkdir /tmp/test-install
	make KDIR=$(pwd) INSTALL_PATH=/tmp/test-install
TARGETS=livepatch -C tools/testing/selftests install

In this case /tmp/test-install will contain the scripts and the modules
compiled targeting the same kernel version from the kernel built from
the kernel tree.

You can also run the tests from the kernel tree but targeting your
currently running system.
Using this approach you can run the tests on machines without kernel
tree and without build environment.

You can also pick the kernel source and run
	make kselftest TARGETS=livepatch

As KDIR wasn't set it builds the livepatch test modules targeting
/lib/modules/<current kernel version/build, and so you can run the
tests against your currently running kernel. This would require kernel-
devel package and gcc.

I hope this answer your question, and provides some info about how to
run the tests on different environments!

Thanks,
  Marcos

Thanks Alexandre and Joe for testing and supporting the change.

Shuah, now that the issue found by that Joe was fixed, do you think the
change is ready to be merged? The patches were reviewed by three
different people already, and I don't know what else can be missing at
this point.

Thanks,
  Marcos

I would have liked doc patch and lib.mk separate. However, I am pulling this
now to get testing done. In the future please keep them separate.

 Running the tests
 -----------------
 
-Test kernel modules are built as part of lib/ (make modules) and need to
-be installed (make modules_install) as the test scripts will modprobe
-them.
+Test kernel modules are built before running the livepatch selftests.  The
+modules are located under test_modules directory, and are built as out-of-tree
+modules.  This is specially useful since the same sources can be built and
+tested on systems with different kABI, ensuring they the tests are backwards
+compatible.  The modules will be loaded by the test scripts using insmod.
 
 To run the livepatch selftests, from the top of the kernel source tree:
 
   % make -C tools/testing/selftests TARGETS=livepatch run_tests
