So, B-GCP-5.4 as well as F-GCP 5.4.0-1011 have RT_GROUP_SCHED on, and that has been turned off by later versions, like F-GCP 5.4.0-1012 and B-GCP-5.4 5.4.0-1016. @cypressyew, can you confirm that it doesn't happen on such kernels?

[Bug 1876697] Re: test_regression_testsuite from ubuntu_qrt_apparmor failed on Focal zVM
All that about CONFIG_RT_GROUP_SCHED seems sensible, but then I am confused as to why is it only showing up in s390x environments? The test is trying to exercise CAP_SYS_NICE, and doing so by calling setpriority(PRIO_PROCESS, 0, -5) Does the test needs to be put into a cgroup with rt allocations if CONFIG_RT_GROUP_SCHED is set? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876697 Title: test_regression_testsuite from ubuntu_qrt_apparmor failed on Focal zVM To manage notifications about this bug go to: https://bugs.launchpad.net/qa-regression-testing/+bug/1876697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1876697] Re: test_regression_testsuite from ubuntu_qrt_apparmor failed on Focal zVM
Reading about SCHED_RR, we had some reports in focal which were about issues setting real-time priority to processes and that appeared to be caused by enabling CONFIG_RT_GROUP_SCHED (which was a request by docker). That happened before release and after 5.4.0-21 (see bug #1873315). And Thadeu's commment #6 points to code which is active only when that config is turned on. So this is something that we released with and the question is whether it should be "fixed" by turning this off again or having properly handled the special cases. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876697 Title: test_regression_testsuite from ubuntu_qrt_apparmor failed on Focal zVM To manage notifications about this bug go to: https://bugs.launchpad.net/qa-regression-testing/+bug/1876697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This issue can be found on older Focal kernels as well (since 5.4.0-24.28, first failure found on zVM, however zKVM passed and LPAR was not tested) With this kernel 5.4.0-29.33, it can be found on LPAR as well (zKVM not tested) But not with other kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876697 Title: test_regression_testsuite from ubuntu_qrt_apparmor failed on Focal zVM To manage notifications about this bug go to: https://bugs.launchpad.net/qa-regression-testing/+bug/1876697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1876697] Re: test_regression_testsuite from ubuntu_qrt_apparmor failed on Focal zVM
My guess is that the test might be hitting the following code from
kernel/sched/core.c:
#ifdef CONFIG_RT_GROUP_SCHED
/*
* Do not allow realtime tasks into groups that have no runtime
* assigned.
*/
if (rt_bandwidth_enabled() && rt_policy(policy) &&
task_group(p)->rt_bandwidth.rt_runtime == 0 &&
!task_group_is_autogroup(task_group(p))) {
retval = -EPERM;
goto unlock;
}
#endif
Which is not really about the capabilities. That is just a guess.

I have seen a similar failure with that specific test when running the tests under virtualbox on x86, though I have not tried it in several years. If this is the expected behavior going forward on s390s, we can address it in qa-regression-testing.
