Hello,

We ran automated tests on a recent commit from this kernel tree:

Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
Commit: 3aaf0a27ffc2 - Merge tag 'clang-format-for-linux-v5.11-rc7' of git://github.com/ojeda/linux

The results of these automated tests are provided below.

Overall result: FAILED (see details below)
Merge: OK
Compile: OK
Selftests compile: FAILED
Tests: PANICKED

All kernel binaries, config files, and logs are available for download here:

https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/index.html?prefix=datawarehouse-public/2021/02/02/622905

One or more kernel tests failed:

aarch64:
❌ selinux-policy: serge-testsuite

x86_64:
❌ selinux-policy: serge-testsuite
❌ LTP lite

We hope that these logs can help you find the problem quickly. For the full
detail on our testing procedures, please scroll to the bottom of this message.

Please reply to this email if you have any questions about the tests that we
ran or if you have any suggestions on how to make future tests more effective.

Compile testing
---------------

We compiled the kernel for 3 architectures:

aarch64:
make options: make LLVM=1 -j30 INSTALL_MOD_STRIP=1 targz-pkg

ppc64le:
make options: make CC=clang -j30 INSTALL_MOD_STRIP=1 targz-pkg

x86_64:
make options: make LLVM=1 -j30 INSTALL_MOD_STRIP=1 targz-pkg


We built the following selftests:

x86_64:
net: fail
bpf: fail
install and packaging: fail

You can find the full log (build-selftests.log) in the artifact storage above.

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚑⚑⚑.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.

Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.

Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.

These should be the failures for this particular set of tests correct?

https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/datawarehouse-public/2021/02/02/622905/build_x86_64_redhat%3A1092370/tests/LTP_lite/9507327_x86_64_1_RHELKT1LITE.FILTERED.fail.log

I am curious, is there any way to get a side by side comparison of the
test results between GCC and clang? In other words, I would like to know
if a test is failing with both compilers versus just clang. This would
help us understand if it is a compiler specific issue or something that
broke the kernel.

Hi Nathan,

We recently moved the mainline tree to use Fedora Rawhide as the base distro, this helps out kdump and other tests which require
updated user space for testing. As a result, there were a few tests that shouldn't have run like LTP Lite. So the log you linked
above is not related to the panic:
https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/datawarehouse-public/2021/02/02/622905/build_x86_64_redhat%3A1092370/tests/LTP_lite/9507327_x86_64_1_RHELKT1LITE.FILTERED.fail.log

This is the version of LTP we run for internal RHEL kernels and therefore isn't supported against upstream kernels. I'm working on a fix
for this now and should be resolved soon, sorry about that.

As far as the panic, it was was triggered on our upstream LTP test, I don't have a corresponding x86_64/LTP mainline(GCC) job since there is a BPF
bug which is causing our jobs to abort while updating the kernel for x86. You will see the following in the logs:

'failed to validate module [something] BTF: -22 '

Here is a regular mainline job for reference where you can it:
https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/datawarehouse-public/2021/02/02/622904/build_x86_64_redhat%3A1092352/tests/9507513_x86_64_1_console.log

As far as comparing tests for mainline run with gcc vs clang, we don't email an upstream ML for regular mainline, so nothing archived.
However, the logs are still published externally and we can always link them here for comparison.

If you like, we could start forwarding you reports for both ? Otherwise, we are working on publishing our results database we use internally,
but this will take some time.

Thanks,
Rachel

Guess this is withΒ CONFIG_DEBUG_INFO_BTF=y and LLVM/Clang?

Today, I played with above and diverse DWARF version settings.
Even recent pahole from Git in combination with up-to-date LLVM/Clang is incompatible with DWARF-v4 and DWARF-v5.
Means all my builds were broken.

Mark Wielaard says:
"I would try to avoid using clang producing DWARF5. It clearly has some
incompatibilities with dwarves/pahole. It should work if you don't set
DEBUG_INFO_DWARF5. Try GCC 11 (which defaults to -gdwarf-5) or an
earlier version (probably at least GCC 8 or higher) using -gdwarf-5
explicitly."

If this is withΒ CONFIG_DEBUG_INFO_BTF=y you should make it unavailable when CC_IS_CLANG=y.

I read that sentence as there are issues with BPF issues with GCC, not
LLVM/Clang.

CONFIG_DEBUG_INFO_BTF is already disabled for the LLVM jobs:

If just adding a link to the GCC logs in the clang reports is not too
much effort for you guys, that would be mighty helpful. I do not mind
sifting through the logs to try and compare results manually (as I just
need to compare the failing clang tests to the GCC run).

If that is not possible for various reasons, please explicitly CC me on
the GCC mainline reports (nat...@kernel.org) and I can just grab the
link myself. Our list gets enough reports as it stands so we can keep
the GCC ones off of this list.

Cheers,
Nathan

We can move to vger+lore. Google groups was faster to setup, but has
many downsides. I don't have resources to pursue archiving the
existing list, and corralling the folks to set up vger and lore, but I
can point people in the right direction and would be supportive.

Hi,

not sure which email to reply so I'm going with this one...

Confirmed with BPF folks that the BTF boot issue from the gcc run is due
to the dwarves incompatibility that was already mentioned and tested a new
dwarves rawhide build which fixes it. According to them it should be
released in a few days.

The two test runs are separate, so the gcc run may not yet be finished
when the clang reports are ready, which makes providing links hard and
we'd have to implement some sort of half-reliable syncing mechanism.
So if you don't mind, we'd just go with the cc for now (once the dwarves
issue is resolved as the kernels just can't boot due to it).

We're hoping to have the public result database within a few months,
and potentially also fully publicly available runs (independent of the
database), both of which should make the comparison process easier.

Moving our CKI friends to BCC, which I perhaps should have done sooner.
If Nathan's cool with it, I would appreciate it. I'm proud that we
have folks that would volunteer to do so, and more than happy to owe
more beers. I look forward to buying those! Being cooped up for so
long due to the pandemic has given me cabin fever.

Yes, that is fine with me! We tried to submit a request for a
vger.kernel.org list once but I do not think that we got any response.
Maybe now that the project is bigger and more relevant, they will be
more responsive to our request.

Migrating off of Google Groups would be nice (although vger has its own
problems at times).

No worries (I'll just choose a very expensive import beer ;-)

Joking aside, it is just a few emails, the guys doing the work are
others (and they are quite busy, so this will likely take weeks or
months), so we can buy them the beers.

Now would be the time to use llvm-linux@vger or linux-llvm@vger if we
want to consider a rename.

I'm not sure precisely what the previous list was:
https://lists.linuxfoundation.org/mailman/listinfo/llvmlinux. I guess
it was llvm...@lists.linuxfoundation.org, not @vger?

Let me know if you prefer that (I already sent the request with the
same name as the google groups one, but these things usually take
time, so I guess you have time to change).

On one hand, linux-llvm looks best (and follows the other linux-*
lists). On the other, people know the project by clang-built-linux...
So, up to you!
