Move from only requesting full file layout segments to requesting layout segments that match our I/O size. This means the server is still free to return a full file layout if it wants, but partial layouts will no longer cause an error.

Merge tag 'kselftest-fix-vfork-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux Pull Kselftest fixes from Mickaël Salaün: "Fix Kselftest's vfork() side effects. As reported by Kernel Test Robot and Sean Christopherson, some tests fail since v6.9-rc1 . This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration. This fixes all these side effects by replacing vfork() with clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and makes the Kselftest framework more robust" Link: https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com Link: https://lore.kernel.org/r/ZjPelW6-AbtYvslu@google.com Link: https://lore.kernel.org/r/20240511171445.904356-1-mic@digikod.net * tag 'kselftest-fix-vfork-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: selftests/harness: Handle TEST_F()'s explicit exit codes selftests/harness: Fix vfork() side effects selftests/harness: Share _metadata between forked processes selftests/pidfd: Fix wrong expectation selftests/harness: Constify fixture variants selftests/landlock: Do not allocate memory in fixture data selftests/harness: Fix interleaved scheduling leading to race conditions selftests/harness: Fix fixture teardown selftests/landlock: Fix FS tests when run on a private mount point selftests/pidfd: Fix config for pidfd_setns_test

If TEST_F() explicitly calls exit(code) with code different than 0, then _metadata->exit_code is set to this code (e.g. KVM_ONE_VCPU_TEST()).

Setting the time namespace with CLONE_NEWTIME returns -EUSERS if the calling thread shares memory with another thread (because of the shared vDSO), which is the case when it is created with vfork(). Fix pidfd_setns_test by replacing test harness's vfork() call with a clone3() call with CLONE_VFORK, and an explicit sharing of the _metadata and self objects. Replace _metadata->teardown_parent with a new FIXTURE_TEARDOWN_PARENT() helper that can replace FIXTURE_TEARDOWN(). This is a cleaner approach and it enables to selectively share the fixture data between the child process running tests and the parent process running the fixture teardown. This also avoids updating several tests to not rely on the self object's copy-on-write property (e.g. storing the returned value of a fork() call).

Unconditionally share _metadata between all forked processes, which enables to actually catch errors which were previously ignored. This is required for a following commit replacing vfork() with clone3() and CLONE_VFORK (i.e. not sharing the full memory) . It should also be useful to share _metadata to extend expectations to test process's forks. For instance, this change identified a wrong expectation in pidfd_setns_test. Because this _metadata is used by the new XFAIL_ADD(), use a global pointer initialized in TEST_F(). This is OK because only XFAIL_ADD() use it, and XFAIL_ADD() already depends on TEST_F().

Fix a race condition when running several FIXTURE_TEARDOWN() managing the same resource. This fixes a race condition in the Landlock file system tests when creating or unmounting the same directory.

The first two address a regression in performance reported to me after the conversion to using SRCU in GPIOLIB that was merged during the v6.9 merge window.

In commit 0518dbe9 ("selftests/mm: fix cross compilation with LLVM") the logic to detect the machine architecture in the Makefile was changed to use ARCH, and only fallback to uname -m if ARCH is unset. However the tests of ARCH were not updated to account for the fact that ARCH is "powerpc" for powerpc builds, not "ppc64". Fix it by changing the checks to look for "powerpc", and change the uname -m logic to convert "ppc64.*" into "powerpc". With that fixed the following tests now build for powerpc again: * protection_keys * va_high_addr_switch * virtual_address_range * write_to_hugetlbfs Link: https://lkml.kernel.org/r/20240506115825.66415-1-mpe@ellerman.id.au Fixes: 0518dbe9 ("selftests/mm: fix cross compilation with LLVM") Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Cc: Mark Brown <broonie@kernel.org> Cc: <stable@vger.kernel.org> [6.4+] Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

The original topology evaluation code initialized cpu_data::topo::llc_id with the die ID initialy and then eventually overwrite it with information gathered from a CPUID leaf. The conversion analysis failed to spot that particular detail and omitted this initial assignment under the assumption that each topology evaluation path will set it up. That assumption is mostly correct, but turns out to be wrong in case that the CPUID leaf 0x80000006 does not provide a LLC ID. In that case, LLC ID is invalid and as a consequence the setup of the scheduling domain CPU masks is incorrect which subsequently causes the scheduler core to complain about it during CPU hotplug: BUG: arch topology borken the CLS domain not a subset of the MC domain Cure it by reusing legacy_set_llc() and assigning the die ID if the LLC ID is invalid after all possible parsers have been tried.

If a line is requested with debounce, and that results in debouncing in software, and the line is subsequently reconfigured to enable edge detection then the allocation of the kfifo to contain edge events is overlooked. This results in events being written to and read from an uninitialised kfifo. Read events are returned to userspace. Initialise the kfifo in the case where the software debounce is already active.

This was missed because of the function pointer indirection. nvidia_smmu_context_fault() is also installed as a irq function, and the 'void *' was changed to a struct arm_smmu_domain. Since the iommu_domain is embedded at a non-zero offset this causes nvidia_smmu_context_fault() to miscompute the offset. Fixup the types.
