2021-10-20selftests/bpf: Use cpu_number only on arches that have itIlya Leoshkevich1-0/+2
cpu_number exists only on Intel and aarch64, so skip the test involing it on other arches. An alternative would be to replace it with an exported non-ifdefed primitive-typed percpu variable from the common code, but there appears to be none.

2021-10-18mm/userfaultfd: selftests: fix memory corruption with thp enabledPeter Xu1-3/+20
In RHEL's gating selftests we've encountered memory corruption in the uffd event test even with upstream kernel: # ./userfaultfd anon 128 4 nr_pages: 32768, nr_pages_per_cpu: 32768 bounces: 3, mode: rnd racing read, userfaults: 6240 missing (6240) 14729 wp (14729) bounces: 2, mode: racing read, userfaults: 1444 missing (1444) 28877 wp (28877) bounces: 1, mode: rnd read, userfaults: 6055 missing (6055) 14699 wp (14699) bounces: 0, mode: read, userfaults: 82 missing (82) 25196 wp (25196) testing uffd-wp with pagemap (pgsize=4096): done testing uffd-wp with pagemap (pgsize=2097152): done testing events (fork, remap, remove): ERROR: nr 32427 memory corruption 0 1 (errno=0, line=963) ERROR: faulting process failed (errno=0, line=1117) It can be easily reproduced when global thp enabled, which is the default for RHEL. It's also known as a side effect of commit 0db282ba2c12 ("selftest: use mmap instead of posix_memalign to allocate memory", 2021-07-23), which is imho right itself on using mmap() to make sure the addresses will be untagged even on arm. The problem is, for each test we allocate buffers using two allocate_area() calls. We assumed these two buffers won't affect each other, however they could, because mmap() could have found that the two buffers are near each other and having the same VMA flags, so they got merged into one VMA. It won't be a big problem if thp is not enabled, but when thp is agressively enabled it means when initializing the src buffer it could accidentally setup part of the dest buffer too when there's a shared THP that overlaps the two regions. Then some of the dest buffer won't be able to be trapped by userfaultfd missing mode, then it'll cause memory corruption as described. To fix it, do release_pages() after initializing the src buffer. Since the previous two release_pages() calls are after uffd_test_ctx_clear() which will unmap all the buffers anyway (which is stronger than release pages; as unmap() also tear town pgtables), drop them as they shouldn't really be anything useful. We can mark the Fixes tag upon 0db282ba2c12 as it's reported to only happen there, however the real "Fixes" IMHO should be 8ba6e8640844, as before that commit we'll always do explicit release_pages() before registration of uffd, and 8ba6e8640844 changed that logic by adding extra unmap/map and we didn't release the pages at the right place. Meanwhile I don't have a solid glue anyway on whether posix_memalign() could always avoid triggering this bug, hence it's safer to attach this fix to commit 8ba6e8640844.

2021-10-18bpf: Rename BTF_KIND_TAG to BTF_KIND_DECL_TAGYonghong Song6-106/+106
Patch set [1] introduced BTF_KIND_TAG to allow tagging declarations for struct/union, struct/union field, var, func and func arguments and these tags will be encoded into dwarf. They are also encoded to btf by llvm for the bpf target. After BTF_KIND_TAG is introduced, we intended to use it for kernel __user attributes. But kernel __user is actually a type attribute. Upstream and internal discussion showed it is not a good idea to mix declaration attribute and type attribute. So we proposed to introduce btf_type_tag as a type attribute and existing btf_tag renamed to btf_decl_tag ([2]). This patch renamed BTF_KIND_TAG to BTF_KIND_DECL_TAG and some other declarations with *_tag to *_decl_tag to make it clear the tag is for declaration. In the future, BTF_KIND_TYPE_TAG might be introduced per [3].

2021-10-17KVM: arm64: selftests: arch_timer: Support vCPU migrationRaghavendra Rao Ananta1-1/+114
Since the timer stack (hardware and KVM) is per-CPU, there are potential chances for races to occur when the scheduler decides to migrate a vCPU thread to a different physical CPU. Hence, include an option to stress-test this part as well by forcing the vCPUs to migrate across physical CPUs in the system at a particular rate. Originally, the bug for the fix with commit 3134cc8beb69d0d ("KVM: arm64: vgic: Resample HW pending state on deactivation") was discovered using arch_timer test with vCPU migrations and can be easily reproduced.

2021-10-11KVM: arm64: selftests: Add test for legacy GICv3 REDIST base partially above ↵Ricardo Koller1-0/+34
IPA range Add a new test into vgic_init which checks that the first vcpu fails to run if there is not sufficient REDIST space below the addressable IPA range. This only applies to the KVM_VGIC_V3_ADDR_TYPE_REDIST legacy API as the required REDIST space is not know when setting the DIST region. Note that using the REDIST_REGION API results in a different check at first vcpu run: that the number of redist regions is enough for all vcpus. And there is already a test for that case in, the first step of test_v3_new_redist_regions.

2021-10-11KVM: arm64: selftests: Add tests for GIC redist/cpuif partially above IPA rangeRicardo Koller1-12/+26
Add tests for checking that KVM returns the right error when trying to set GICv2 CPU interfaces or GICv3 Redistributors partially above the addressable IPA range. Also tighten the IPA range by replacing KVM_CAP_ARM_VM_IPA_SIZE with the IPA range currently configured for the guest (i.e., the default). The check for the GICv3 redistributor created using the REDIST legacy API is not sufficient as this new test only checks the check done using vcpus already created when setting the base. The next commit will add the missing test which verifies that the KVM check is done at first vcpu run.

2021-10-11KVM: arm64: selftests: Add some tests for GICv2 in vgic_initRicardo Koller1-32/+79
Add some GICv2 tests: general KVM device tests and DIST/CPUIF overlap tests. Do this by making test_vcpus_then_vgic and test_vgic_then_vcpus in vgic_init GIC version agnostic.

Make vm_gic_create GIC version agnostic in the vgic_init test. Also add a nr_vcpus arg into it instead of defaulting to NR_VCPUS. No functional change.

2021-10-11KVM: arm64: selftests: Make vgic_init gic version agnosticRicardo Koller1-61/+95
As a preparation for the next commits which will add some tests for GICv2, make aarch64/vgic_init GIC version agnostic. Add a new generic run_tests function(gic_dev_type) that starts all applicable tests using GICv3 or GICv2. GICv2 tests are attempted if GICv3 is not available in the system. There are currently no GICv2 tests, but the test passes now in GICv2 systems.

2021-10-08selftests/bpf: Skip verifier tests that fail to load with ENOTSUPPIlya Leoshkevich1-1/+11
The verifier tests added in commit c48e51c8b07a ("bpf: selftests: Add selftests for module kfunc support") fail on s390, since the JIT does not support calling kernel functions. This is most likely an issue for all the other non-Intel arches, as well as on Intel with !CONFIG_DEBUG_INFO_BTF or !CONFIG_BPF_JIT. Trying to check for messages from all the possible add_kfunc_call() failure cases in test_verifier looks pointless, so do a much simpler thing instead: just like it's already done in do_prog_test_run(), skip the tests that fail to load with ENOTSUPP.
