[Buildroot] [PATCH] libseccomp: Add new config option to build and install tests

[Markos Chandras]

Add new config option to allow building and installing the libseccomp
testsuite on the target. It's useful for testing the kernels'
seccomp behavior for the target architecture.

You should be adding $(TARGET_MAKE_ENV) in front of $(MAKE). Anyway,
there is a better solution which will make this define unnecessary. See
comments below.

> +endef

Instead of doing a define to build the tests, you can change the target
and use the 'check-build' one, which will not only build the tests and
tools, but also will trigger the 'all' target. So:

ifeq ($(BR2_PACKAGE_LIBSECCOMP_TESTS),y)
# The 'check-build' target builds the tests and tools, and also
# triggers the 'all' target.
LIBSECCOMP_MAKE_OPTS += check-build

> +endef

I would remove this empty line since you are adding to the hooks
variable the define immediately above.

> +LIBSECCOMP_POST_BUILD_HOOKS += LIBSECCOMP_TESTS_BUILD

This post-build hook is not needed since the define has been replaced by
the LIBSECCOMP_MAKE_OPTS line.

And I would remove this empty line as well.

This has the effect of installing one .py file for each test even if
Python is not installed on the target. They are pretty small, so maybe
we don't care, but it doesn't look really nice.

Also, this whole thing seems pretty crappy in libseccomp. Why don't
they have simply a --enable-tests option, which will simply do the
right thing?

Thanks,

Hmm makes sense. I will rework it then.

It's probably because this is yet another testsuite and like any other
package testsuite you don't really need it installed. it's supposed to
run as part of package verification during build and installation. but
for cross-builds, it's useful to have it on the target.

Build test for MIPS architecture. All fine. Binary files built for the
right architecture and no more .py files installed on target. Checked
that now the tests and tools are installed in /usr/share/libseccomp/.

I think the reason I still don't apply this patch is because I'm not
happy with Buildroot doing all this complicated logic to install the
tests, and that it should be part of the libseccomp build system to
provide a mechanism to do that easily.

So if you want to see this integrated, I would recommend to work with
upstream libseccomp to implement something allowing the installation of
tests, and then use it in Buildroot.

Best regards,

Thomas
