[Potential Regression] dscr_inherit_exec_test from powerpc in ubuntu_kernel_selftests failed on B/E/F

Bug Description

[Impact]
Code that touches DSCR user MSR does not set dscr_inherit, which breaks DSCR restore doing context switches and inheritance when forking. DSCR is used to control cache hinting. This is caused by lack of kernel interrupt when the DSCR user MSR is written, which is controlled by FSCR which would otherwise cause a facility unavailable interrupt.

[Test case]
apt-get source linux
cd linux-5.4.0/tools/testing/tools/selftests/powerpc/
make -j 32
make -C dscr run_tests
make -C ptrace run_tests
make -C tm run_tests

Look up for "not ok" versus "ok", specially for dscr_inherit_exec_test, ptrace-tar and tm-resched-tar.

[Potential regression]
Manipulating DSCR might break on different machines (with DTs containing
/cpus/ibm,powerpc-cpu-features, for example). Code that does so might crash because the facility unavailable interrupt handling might be not working correctly.

Since this 5.3.0-64.58 is a respin for 5.3.0-63.57, I think we can call this a potential regression.

On Bionic P8, I can reproduce this issue against proposed kernel (4.15.0-114.115) with source code in 4.15.0-112. Indicating this might be a kernel issue instead of a test case issue.

powerpc/64s: Save FSCR to init_task.thread.fscr after feature init

BugLink: https://bugs.launchpad.net/bugs/1885176

commit 912c0a7f2b5daa3cbb2bc10f303981e493de73bd upstream.

At boot the FSCR is initialised via one of two paths. On most systems
it's set to a hard coded value in __init_FSCR().

On newer skiboot systems we use the device tree CPU features binding,
where firmware can tell Linux what bits to set in FSCR (and HFSCR).

    In both cases the value that's configured at boot is not propagated
    into the init_task.thread.fscr value prior to the initial fork of init
    (pid 1), which means the value is not used by any processes other than
    swapper (the idle task).

    For the __init_FSCR() case this is OK, because the value in
    init_task.thread.fscr is initialised to something sensible. However it
    does mean that the value set in __init_FSCR() is not used other than
    for swapper, which is odd and confusing.

    The bigger problem is for the device tree CPU features case it
    prevents firmware from setting (or clearing) FSCR bits for use by user
    space. This means all existing kernels can not have features
    enabled/disabled by firmware if those features require
    setting/clearing FSCR bits.

    We can handle both cases by saving the FSCR value into
    init_task.thread.fscr after we have initialised it at boot. This fixes
    the bug for device tree CPU features, and will allow us to simplify
    the initialisation for the __init_FSCR() case in a future patch.

This test failure is caused by the kernel not setting dscr_inherit when the user dscr MSR is written to. Which is caused by FSCR not raising a facility unavailable interrupt. Which is ironic as one of the other patches that is backported is 993e3d96fd08c3ebf7566e43be9b8cd622063e6d ("powerpc/64s: Don't let DT CPU features set FSCR_DSCR"), which should prevent this situation.

The reason dscr_inherit_test does not fail is because it writes to the kernel MSR first. Changing dscr_inherit_exec_test to do the same, it passes.

Testing 5.8 shows that it's fixed somehow, though I haven't found the exact commit that would fix this. Reverting 912c0a7f2b5daa3cbb2bc10f303981e493de73bd ("powerpc/64s: Save FSCR to init_task.thread.fscr after feature init") seems reasonable here.

But failing to inherit dscr would cause cache performance regressions that are hard to justify respining the kernel for.

Cascardo.

Apparently, cherry-picking 0828137e8f16721842468e33df0460044a0c588b ("powerpc/64s: Don't init FSCR_DSCR in __init_FSCR()") fixes the issue. Which explains why 5.8 does not show the problem.

Building a kernel with that patch applied so I can test it.
