Hello all,
I'd appreciate some help from the BPF and s390x communities...
Some background: I'm finalizing a patch series enabling full cross-endian
support for libbpf and selftests/bpf, and testing with mips64 so far. This
arch makes switching the build byte-order trivial and has been very handy
for A/B testing, but lacks some basic support (bpf2bpf call, kfuncs, etc.)
making for poor selftests coverage.
To finish testing I thought (optimistically?) to cross-build kernel and
bpf selftests from x86_64 to s390x. That configuration might also be used
later on bpf-ci for regression testing endian support and sharing the load
of s390x builds.
Locally, the build succeeds but when running it under QEMU I see kernel
crashes trying to load any modules (e.g. prng or bpf_testmod).
The build/test setup uses Ubuntu and gcc:
kodidev:~/linux$ lsb_release -d
Description: Ubuntu 22.04.4 LTS
kodidev:~/linux$ s390x-linux-gnu-gcc --version
s390x-linux-gnu-gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

The code targets bpf/master, and I've researched QEMU/s390x usage details
online but mainly follow https://docs.kernel.org/bpf/s390.html. For rootfs
I take the same s390x image used by the kernel-patches bpf-ci.
The kernel .config used is attached, and the QEMU command-line is below:
qemu-system-s390x -cpu max,zpci=on -smp 2 -nographic -m 1G \
-object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-ccw,rng=rng0 \
-device virtio-net-ccw,netdev=eth0 \
-netdev user,id=eth0,hostfwd=tcp::2224-:22 \
-serial mon:stdio \
-nodefaults \
-kernel bzImage-s390x \
-drive file=root-s390x-glibc.qcow2,if=virtio,format=qcow2 \
-append "rootwait root=/dev/vda rw net.ifnames=0 biosdevname=0 console=ttyS1"
After successfully booting, the crashes are easily reproduced:

Has anyone encountered this before, or is able to reproduce?
Could someone share a "known good" kernel .config working in the past?
I'd be grateful for any advice or helpful suggestions.
Thanks,
Tony

Hi Ilya,
Thanks for following up. As it happens, I did this the day before out of
desperation after trying various kernel config and rootfs changes
with no luck, and can confirm the system runs faster and without the
kernel crashes noted above. Certainly the latest QEMU seems mandatory.
The good news is that 99% of tests with my cross-compiled test_progs
work as expected out of the box, and some of the failing ones helped
troubleshoot a few hidden libbpf issues. I'll outline the remaining
failures for your feedback and comparison with native-built tests.
I used the command line:
./test_progs -d get_stack_raw_tp,stacktrace_build_id,verifier_iterating_callbacks,tailcalls
which includes the current DENYLIST.s390x as well as 'tailcalls', which
is also excluded by the kernel-patches/bpf s390x CI. I note the CI
excludes several more tests that seem to work. Any idea why that is?
For reference, the issue with 'tailcalls/tailcall_hierarchy_count' is an
RCU stall and kernel hang:
root@(none):/usr/libexec/kselftests-bpf# ./test_progs -v --debug -n 332/19

Have you seen this fault before? Is the inode warning expected by the
test?
Aside from the tests above, I see only 3 failing tests:

Summary: 559/4166 PASSED, 98 SKIPPED, 3 FAILED
The test 'token/obj_priv_implicit_token_envvar' fails with both cross
and native-compiled test_progs, so unrelated to my patch. A quick strace
suggests like the child exits before it's waited for, and errno 3 is
'No such process'. Does that sound familiar? Maybe a race?
The 'verif_scale_pyperf600' and 'map_ptr' test failures both succeed if
run by native-compiled test_progs (copied from kernel-patches/bpf CI),
so I'm now trying to troubleshoot and compare native vs. cross-compiled
tests. The 'map_ptr' test uses a "light skeleton", and is proving tricky
to debug.
In any case, I'll also send out my patch series given the overall good
test results, and hope an eagle-eyed expert can spot something.
I'd appreciate anyone's thoughts or advice on troubleshooting these
errors. (CCing Alexei on light skeleton)
Thanks

Yes, this is caused by:
/* attach fail due to wrong ref_ctr_offs on one of the uprobes */
attach_uprobe_fail_refctr(skel);
The fault is a user fault, not a kernel fault. I could not reproduce it
on a real s390x machine. This may be an emulation problem, since
apparently the kernel does not recognize that "0000 illegal" is an
uprobe. Quite some time ago I fixed a similar issue in this area,
perhaps it's a new flavour. I will investigate.

Ilya

Hi Ilya,
I think you should wait for a while, as I'll fix another tailcall issue
in near future. After fixing the issue, you can port them both in one shot.
Thanks,
Leon

Hi Ilya,
A brief update with some good news: the 3 test failures above have been
resolved and all expected tests now pass on QEMU/s390x under x86_64.
Test '#165 map_ptr:FAIL' was a bug in my light-skeleton code, and fixed in
my patch series v2:
https://lore.kernel.org/bpf/cover.1724313164.git.tony.ambardar@gmail.com/
Test '#402/9 token/obj_priv_implicit_token_envvar:FAIL' was a problem in my
rootfs configuration and now passes after resolving.
Test '#525 verif_scale_pyperf600:FAIL' was caused by clang miscompilation
exposed by my use of clang-19 and clang-20. The test passes when built
with clang-17 (used by BPF CI) or clang-18 which I switched to use.
One symptom of the problem is easily seen by manually compiling:
$ clang-18 -g -Wall -Werror -D__TARGET_ARCH_s390 -mbig-endian -Itools/testing/selftests/bpf/tools/include -Itools/testing/selftests/bpf -Itools/include/uapi -Itools/testing/selftests/usr/include -Wno-compare-distinct-pointer-types -idirafter /usr/lib/llvm-18/lib/clang/18/include -idirafter /usr/local/include -idirafter /usr/lib/gcc-cross/s390x-linux-gnu/11/../../../../s390x-linux-gnu/include -idirafter /usr/include/s390x-linux-gnu -idirafter /usr/include -DENABLE_ATOMICS_TESTS -O2 --target=bpfeb -c tools/testing/selftests/bpf/progs/pyperf600.c -mcpu=v3 -o pyperf600.clang18.bpf.o

[27] .symtab SYMTAB 0000000000000000 14f048 0001e0 18 1 12 8
Notice that the .symtab has shrunk by ~200X for example going to clang-19!

x86 has the same issue where clang19 generated code will cause verification
failure. Eduard is working on this.

This is a known issue. In llvm18, all labels (to identify basic blocks) are in symbol table.
Those labels are removed from symbol table in llvm19.

Glad to hear this a known issue being looked at now. A quick search on my part found nothing, so sorry for the noise and thanks for clarifying.
