[PATCH 00/34] selftests: Fix incorrect kernel headers search path

[PATCH 00/34] selftests: Fix incorrect kernel headers search path

[Mathieu Desnoyers]

Hi,

This series fixes incorrect kernel header search path in kernel
selftests.

Near the end of the series, a few changes are not tagged as "Fixes"
because the current behavior is to rely on the kernel sources uapi files
rather than on the installed kernel header files. Nevertheless, those
are updated for consistency.

There are situations where "../../../../include/" was added to -I search
path, which is bogus for userspace tests and caused issues with types.h.
Those are removed. 

Thanks,

Mathieu

I am taking several patches in the series with an exception
when maintainers want to take them through theirs.

I will apply to mine and take this through.

Please resubmit as separate patch with [PATCH bpf-next] subj
and cc bpf@vger, so that BPF CI can test it on various architectures
and config combinations.

[PATCH 04/34] selftests: core: Fix incorrect kernel headers search path

(It might be useful to add a "Fixes" tag as well to clearly indicate the
dependence with a specific commit and better understand the fix.)

(and add all the individual maintainers of the files you modify -- feel
free to use 'b4' to help you for this task ;-) )

I only looked at the modification here with MPTCP selftests and it looks
good to me. It makes sense because if KHDR_INCLUDES is not set, it will
be set later by lib.mk I suppose.

Just one small thing: I guess you can also remove "top_srcdir" variable
that is no longer used, right? I see that "lib.mk" uses a variable with
the same name but it overrides its value anyway. But it is likely I
missed something there :)

If indeed it is no longer needed, I guess a few Makefile can be adapted
according to:

  git grep top_srcdir -- tools/testing/selftests/*/

I guess most of these Makefile are very similar, no? For MPTCP, we
simply looked at what was done elsewhere :)

Cheers,
Matt

Just a bit of context: I found this problematic pattern in my own 
selftests (rseq and membarrier), and figured that it was an issue all 
across the board. I did an initial single-patch fix, and then split it 
up in 34 patches based on feedback from Shuah Khan.

I know it should have a Fixed ... tag, but I simply don't have time to 
do the historical investigation work for all the 34 patches form this 
patchset. Perhaps someone else is up to the task ?

If this can be automated, then perhaps Shuah can use it to append the 
relevant information ?

Yes, this should perhaps come as additional fixes on top of my series. I 
don't have time to do it myself though.

Anyone willing to contribute it ?

Yes, I did likewise.

Thanks for the feedback,

[PATCH 25/34] selftests: seccomp: Fix incorrect kernel headers search path

[Mathieu Desnoyers]

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).

[PATCH 31/34] selftests: iommu: Use installed kernel headers search path

[Mathieu Desnoyers]

Use $(KHDR_INCLUDES) as lookup path for installed kernel headers rather
than using kernel headers in include/uapi from the source kernel tree
kernel headers.

Remove bogus ../../../../include/ from the search path, because
kernel source headers are not needed by those user-space selftests, and
it causes issues because -I paths are searched before -isystem paths,
and conflicts for files appearing both in kernel sources and in uapi
headers with incompatible semantics (e.g. types.h).

Use $(KHDR_INCLUDES) as lookup path for installed kernel headers rather
than using kernel headers in include/uapi from the source kernel tree
kernel headers.

Not in this form. They break the build.

It's not the format, but the patch itself is incorrect.

Thanks again for taking care of this. I did out of tree build testing on
x86 on linux-kselftest next with these patches below. I haven't seen
any problems introduced by the patch set.

>>    selftests: dma: Fix incorrect kernel headers search path
This one needs a change and I will send a patch on top of yours.
Even with that this test depends on unexported header from the
repo and won't build out of tree. This is not related to your
change.

>>    selftests: mount_setattr: Fix incorrect kernel headers search path
This one fails to build with our without patch - an existing error.

I have to do cross-build tests on arm64 and other arch patches still.
This will happen later this week.

>>    selftests: arm64: Fix incorrect kernel headers search path

drivers patch below had arch specific tests - testing todo

The rest looks good. I will try to run bpf patches on my system.
I do have clang, llvm installed on mine. TODO

I am seeing problem with selftests/dma and selfttests/user_events.

1. selftests: dma: Fix incorrect kernel headers search path

dma test no longer builds. This test depends on linux/map_benchmark.h
which is not included in uapi

The order of include directorries -isystem followed by installed kernel
headers, breaks the test build with the change to use KHDR_INCLUDES


I am going to revert this patch for now and figure a longer term fix.
The problem is the dependency on a non-uapi file: linux/map_benchmark.h

Fixes: 8ddde07a3d28 ("dma-mapping: benchmark: extract a common
header file for map_benchmark definition") change added this
dependency on including linux/map_benchmark.h

Christoph, Do you see this map_benchmark.h as part of uapi?


2. selftests: user_events: Fix incorrect kernel headers search path
This one depends on linux/user_events.h which has bee removed from
uapi in this commit:

commit 5cfff569cab8bf544bab62c911c5d6efd5af5e05
Author: Steven Rostedt (Google) <rostedt@goodmis.org>
Date:   Fri Apr 1 14:39:03 2022 -0400

     tracing: Move user_events.h temporarily out of include/uapi

This isn't a regression from 6.2 - this test stopped building once
user_events.h has been removed from uapi. I will add a note that
this test depends on a non-uapi header and can't be built at the
moment.
