The changes doesn't change the current functionality. The changes on
lib.mk are both for simplification and also clarification, like in the
case of not handling TEST_GEN_MODS_DIR directly.
These changes apply on top of the current kselftest-next branch. Please
review!

We don't need new targets only to run two make modules and make clean.
We can test if TEST_GEN_MODS_DIR is specified, and then run the
commands.

We should ask the kernel test robot machine owners to install kernel-devel
package in order to have this fixed.

Or maybe ask them to change the reproducer to specify KDIR to the git tree,
instead of /lib/modules/?

This would be a regression to automated test rings. Do you have any other
solutions?
We could remove livepatch from default test until these changes are made
to test ring environments?

I would say that we could skip the these tests if kernel-devel package is not
installed. Would it be acceptable? At least we would avoid such issues like this
in the future as well.

I couldn't reproduce this one locally. Shuah, have you seen this issue in your
setup? I followed the steps to reproduce this issue (it's the same sequence
already reported in earlier patches...)

We have to check and skip build. Something we could do in the livepatch
Makefile. Can you send patch for this - I will oull this in for next
so we don't break test rings.

I added a new patch in the same patchset that would cover this, skipping the
build and test if kernel-devel is not installed. The patchset was sent earlier
today. Please check if the new patch fixes things on the build robot.

Hi Shuah, Hi Marcos,
Sorry for this wrong report. The files are organized in a different way
in the bot and cause this issue. We have fixed the bot to explicitly
set KDIR to the correct path before building the selftests. The patch
[1] can also work well in bot's environment.

Hi Yujie, thanks for letting us know that the bot had different settings. Either
way the patch you mentioned should help to reduce noise in the future on
bot's that doesn't have kernel-devel installed.
Again, thanks a lot for fixing the issue!

Hi Marcos,
This seems to be a warning when compiling futex selftest.
linux/tools/testing/selftests/futex$ make
Makefile:11: warning: overriding recipe for target 'all'
./lib.mk:62: warning: ignoring old recipe for target 'all'
There is no such warning if this patch is not applied. Looks like it is
due to the "all" target is defined in lib.mk but overridden in futex
Makefile? Could you please help take a look?
Thanks,
Yujie

I believe that I understood what's going on:
Before this patch, the 'all' from lib.mk target didn't have a "recipe" only
dependencies. The TARGET_GEN_MODS_DIR variable was used while resolving the
dependencies from it.
The proposed patch simplified the process by removing the gen_mods_dir target,
and checked TARGET_GEN_MODS_DIR variable as a recipe.
Per my local tests, we can have two targets with the same name on two different
Makefiles (one that includes in the other in case), as long as only one of them
have a recipe (commands to execute). The dependencies of the target
on the included file would will be checked and executed either way.
But, if both targets have commands to execute, make will say the target was
overridden. In both cases, only the target from the file that includes the other
will execute. I believe this matches the current expectation of the futex
selftests, as they jump on into "functional" directory and execute the tests
there. That makefile also includes lib.mk...
It seems that planned to include more directories since they introduced the
selftests, but never did:
commit 2aa8470f02a9b9e6a410d1264fe6c8fa6c402eff
Author: Darren Hart <[email protected]>

selftests: Add futex functional tests
The futextest testsuite [1] provides functional, stress, and
performance tests for the various futex op codes. Those tests will be of
more use to futex developers if they are included with the kernel
source.
Copy the core infrastructure and the functional tests into selftests,
but adapt them for inclusion in the kernel:
- Update the Makefile to include the run_tests target, remove reference
to the performance and stress tests from the contributed sources.
- Replace my dead IBM email address with my current Intel email address.
- Remove the warrantee and write-to paragraphs from the license blurbs.
- Remove the NAME section as the filename is easily determined. ;-)
- Make the whitespace usage consistent in a couple of places.
- Cleanup various CodingStyle violations.
A future effort will explore moving the performance and stress tests
into the kernel.
1. http://git.kernel.org/cgit/linux/kernel/git/dvhart/futextest.git
Either way, if my change adds a new warning, I think that we can drop that patch
and move on. OTOH, I believe that futex selftests could be simplified in order
to remove this awkward setup to run their tests.
