2024-10-20KVM: selftests: Fix out-of-bounds reads in CPUID test's array lookupsSean Christopherson1-1/+1
When looking for a "mangled", i.e. dynamic, CPUID entry, terminate the walk based on the number of array _entries_, not the size in bytes of the array. Iterating based on the total size of the array can result in false passes, e.g. if the random data beyond the array happens to match a CPUID entry's function and index.

Some distros switched gcc to '-march=x86-64-v3' by default and while it's hard to find a CPU which doesn't support it today, many KVM selftests fail with ==== Test Assertion Failure ==== lib/x86_64/processor.c:570: Unhandled exception in guest pid=72747 tid=72747 errno=4 - Interrupted system call Unhandled exception '0x6' at guest RIP '0x4104f7' The failure is easy to reproduce elsewhere with $ make clean && CFLAGS='-march=x86-64-v3' make -j && ./x86_64/kvm_pv_test The root cause of the problem seems to be that with '-march=x86-64-v3' GCC uses AVX* instructions (VMOVQ in the example above) and without prior XSETBV() in the guest this results in #UD.

2024-10-17maple_tree: add regression test for spanning store bugLorenzo Stoakes1-0/+84
Add a regression test to assert that, when performing a spanning store which consumes the entirety of the rightmost right leaf node does not result in maple tree corruption when doing so. This achieves this by building a test tree of 3 levels and establishing a store which ultimately results in a spanned store of this nature.

2024-10-17maple_tree: check for MA_STATE_BULK on setting wr_rebalanceSidhartha Kumar1-0/+26
It is possible for a bulk operation (MA_STATE_BULK is set) to enter the new_end < mt_min_slots[type] case and set wr_rebalance as a store type. This is incorrect as bulk stores do not rebalance per write, but rather after the all of the writes are done through the mas_bulk_rebalance() path. Therefore, add a check to make sure MA_STATE_BULK is not set before we return wr_rebalance as the store type. Also add a test to make sure wr_rebalance is never the store type when doing bulk operations via mas_expected_entries() This is a hotfix for this rc however it has no userspace effects as there are no users of the bulk insertion mode.

2024-10-17selftests/mm: replace atomic_bool with pthread_barrier_tEdward Liaw3-10/+12
Patch series "selftests/mm: fix deadlock after pthread_create". On Android arm, pthread_create followed by a fork caused a deadlock in the case where the fork required work to be completed by the created thread. Update the synchronization primitive to use pthread_barrier instead of atomic_bool. Apply the same fix to the wp-fork-with-event test. This patch (of 2): Swap synchronization primitive with pthread_barrier, so that stdatomic.h does not need to be included. The synchronization is needed on Android ARM64; we see a deadlock with pthread_create when the parent thread races forward before the child has a chance to start doing work.

The hmm2 double_map test was failing due to an incorrect buffer->mirror size. The buffer->mirror size was 6, while buffer->ptr size was 6 * PAGE_SIZE. The test failed because the kernel's copy_to_user function was attempting to copy a 6 * PAGE_SIZE buffer to buffer->mirror. Since the size of buffer->mirror was incorrect, copy_to_user failed. This patch corrects the buffer->mirror size to 6 * PAGE_SIZE.

2024-10-09selftests: sched_ext: Add sched_ext as proper selftest targetBjörn Töpel2-43/+37
The sched_ext selftests is missing proper cross-compilation support, a proper target entry, and out-of-tree build support. When building the kselftest suite, e.g.: make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- \ TARGETS=sched_ext SKIP_TARGETS="" O=/output/foo \ -C tools/testing/selftests install or: make ARCH=arm64 LLVM=1 TARGETS=sched_ext SKIP_TARGETS="" \ O=/output/foo -C tools/testing/selftests install The expectation is that the sched_ext is included, cross-built, the correct toolchain is picked up, and placed into /output/foo. In contrast to the BPF selftests, the sched_ext suite does not use bpftool at test run-time, so it is sufficient to build bpftool for the build host only. Add ARCH, CROSS_COMPILE, OUTPUT, and TARGETS support to the sched_ext selftest. Also, remove some variables that were unused by the Makefile.
