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
| * selftests/harness: Handle TEST_F()'s explicit exit codesMickaël Salaün2024-05-111-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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()). We need to keep in mind that _metadata->exit_code can be KSFT_SKIP while the process exit code is 0.

| * selftests/harness: Fix vfork() side effectsMickaël Salaün2024-05-112-25/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * selftests/harness: Share _metadata between forked processesMickaël Salaün2024-05-111-11/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

This fixes a race condition in the Landlock file system tests when creating or unmounting the same directory. Using clone3() with CLONE_VFORK guarantees that the child and grandchild test processes are sequentially scheduled. This is implemented with a new clone3_vfork() helper replacing the fork() call.

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: 0518dbe97fe6 ("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>

Since each architecture has already defined names and versions in vdso_config.h, it is proper to include vdso_config.h to get version and name for all archs.

On systems where systemd-udev uses MACAddressPolicy=persistent (default since systemd version 242), this will result in some net devices having the same MAC address since they were created with the same name in the initial network namespace. In turn, this leads to arping / ndisc6 failing since packets are dropped by the bridge's loopback filter.

A late bug was reported by Robert Richter that the Restricted CXL Host (RCH) support was missing in the CXL endpoint access_coordinate calculation. The missing support causes the topology iterator to stumble over a NULL pointer and triggers a kernel OOPS on a platform with CXL 1.1 support. The fix bypasses RCH topology as the access_coordinate calculation is not necessary since RCH does not support hotplug and the memory region exported should be covered by the HMAT table already. A unit test is also added to cxl_test to check against future regressions on the topology iterator" * tag 'cxl-fixes-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl: Fix cxl_endpoint_get_perf_coordinate() support for RCH

But it is broken as parent exits after creating child. Hence calling the atexit() function early. That's not it. The child exits after creating its child and so on. The parent cannot wait to get the termination status for its children as it'll keep on holding the resources until the new pkey allocation fails. It is impossible to wait for exits of all the grand and great grand children. Hence the restoring of nr_hugepages value from parent is wrong. Let's save/restore the nr_hugepages settings in the launch script instead of doing it in the test.

This fixes a warning "Unpatched return thunk in use. This should not happen!" when running KVM selftests. Everything else is small bugfixes and selftest changes: - Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure where KVM would allow userspace to refresh the cache with a bogus GPA. The bug has existed for quite some time, but was exposed by a new sanity check added in 6.9 (to ensure a cache is either GPA-based or HVA-based). - Drop an unused param from gfn_to_pfn_cache_invalidate_start() that got left behind during a 6.9 cleanup. - Fix a math goof in x86's hugepage logic for KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow (detected by KASAN). - Fix a bug where KVM incorrectly clears root_role.direct when userspace sets guest CPUID. - Fix a dirty logging bug in the where KVM fails to write-protect SPTEs used by a nested guest, if KVM is using Page-Modification Logging and the nested hypervisor is NOT using EPT. x86 PMU: - Drop support for virtualizing adaptive PEBS, as KVM's implementation is architecturally broken without an obvious/easy path forward, and because exposing adaptive PEBS can leak host LBRs to the guest, i.e. can leak host kernel addresses to the guest. - Set the enable bits for general purpose counters in PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD processors. - Disable LBR virtualization on CPUs that don't support LBR callstacks, as KVM unconditionally uses PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and would fail on such CPUs. Tests: - Fix a flaw in the max_guest_memory selftest that results in it exhausting the supply of ucall structures when run with more than 256 vCPUs. - Mark KVM_MEM_READONLY as supported for RISC-V in set_memory_region_test" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (30 commits) KVM: Drop unused @may_block param from gfn_to_pfn_cache_invalidate_start() KVM: selftests: Add coverage of EPT-disabled to vmx_dirty_log_test KVM: x86/mmu: Fix and clarify comments about clearing D-bit vs. write-protecting KVM: x86/mmu: Remove function comments above clear_dirty_{gfn_range,pt_masked}() KVM: x86/mmu: Write-protect L2 SPTEs in TDP MMU when clearing dirty status KVM: x86/mmu: Precisely invalidate MMU root_role during CPUID update KVM: VMX: Disable LBR virtualization if the CPU doesn't support LBR callstacks perf/x86/intel: Expose existence of callback support to KVM KVM: VMX: Snapshot LBR capabilities during module initialization KVM: x86/pmu: Do not mask LVTPC when handling a PMI on AMD platforms KVM: x86: Snapshot if a vCPU's vendor model is AMD vs. Intel compatible KVM: x86: Stop compiling vmenter.S with OBJECT_FILES_NON_STANDARD KVM: SVM: Create a stack frame in __svm_sev_es_vcpu_run() KVM: SVM: Save/restore args across SEV-ES VMRUN via host save area KVM: SVM: Save/restore non-volatile GPRs in SEV-ES VMRUN via host save area KVM: SVM: Clobber RAX instead of RBX when discarding spec_ctrl_intercepted KVM: SVM: Drop 32-bit "support" from __svm_sev_es_vcpu_run() KVM: SVM: Wrap __svm_sev_es_vcpu_run() with #ifdef CONFIG_KVM_AMD_SEV KVM: SVM: Create a stack frame in __svm_vcpu_run() for unwinding KVM: SVM: Remove a useless zeroing of allocated memory ...

This makes the guest never reach the code which frees the ucall struct and since a fixed pool of 512 ucall structs is used, the test starts to fail when more that 256 vCPUs are used. Fix that by replacing the manual register reset with a loop in the guest code.

For the edge case where there are zero GP counters, follow the spirit of the architecture, not the SDM's literal wording, which doesn't account for this possibility and would require the CPU to set _all_ bits in PERF_GLOBAL_CTRL.
