Looking at the log file, it seems like the xdp_helper in net/lib is not 
compiled so calling this helper from the test fails. There is similar 
failures where xdp_dummy.bpf.o in net/lib is not compiled either.

Error opening object 
/usr/src/perf_selftests-x86_64-rhel-9.4-kselftests-59dd07db92c166ca3947d2a1bf548d57b7f03316/tools/testing/selftests/net/lib/xdp_dummy.bpf.o: 
No such file or directory

I'm still not sure what the root cause is. On my machine, these files 
are compiled correctly.

Thanks,
Quang Minh.

Same here. The get built and installed correctly for me.
Oliver Sang, how does LKP build the selftests? I've looked at the
artifacts and your repo for 10min, I can't find it.
The net/lib has a slightly special way of getting included, maybe
something goes wrong with that.

I understand why now. Normally, this command is used to run test
pwd: tools/testing/selftests
make TARGETS="drivers/net" run_tests

The LKP instead runs this
make quicktest=1 run_tests -C drivers/net

So the Makefile in tools/testing/selftests is not triggered and net/lib 
is not included either.

Thanks,
Quang Minh.

hi Jakub and Quang Minh, sorry for the false positive report. And thanks for
helping root cause the issue in LKP side. We will fix the bot asap to avoid
missing the required dependencies during the kselftest.

I've created a pull request, please help me to review it:
