2026-07-31KVM: selftests: Only link to VFIO library on x86Sean Christopherson
Link to the VFIO library only on architectures where it's actually needed, i.e. only on architectures that support irq_test, which is currently x86-only. The irq_test series, which pulled in VFIO support, effectively raced with commit e65f1bf8a2db ("vfio: selftests: Extend container/iommufd setup for passing vf_token"). I.e. when the KVM test was posted, pulling in libvfio.mk didn't require linking to any new libraries other than VFIO itself. Now that libvfio.mk pulls in luuid, unconditionally linking in support for VFIO is quite onerous, especially when cross-compiling, as it requires installing what is effectively an unused library on four architectures. Eventually KVM selftests will likely support irq_test and thus need to link to VFIO on architectures other than x86, but at least then there will be some amount of gain for the pain.

2026-07-31selftests/verification: Rearrange the wwnr_printk testGabriele Monaco
The wwnr_printk test expects no reactions in some situations, after fixing the bash assertion, the test is failing because expecting no reaction after a previous step had reactions is flaky without making sure all buffers are flushed. Wait for reactions to be over when expected by polling dmesg for an interval without any rv message. Also simplify the load function to stop loads as soon as a reaction occurs, this limits the number of lines to flush and makes tests overall faster and more stable.

2026-07-31selftests/verification: Fix wrong errexit assumptionGabriele Monaco
RV selftest rely on bash errexit (set -e) to terminate with error, when a step is expected to return false, the following syntax is used: ! cmd This however prevents the test from exiting when cmd is false (desired) but doesn't exit if cmd is true, since commands prefixed with ! are explicitly excluded from errexit. Use the syntax ! cmd || false Which ends up checking the exit value of ! cmd and supplies a false command for errexit to evaluate.

In setup_namespace(), f_mountinfo is opened with fopen() at line 115 but is never closed. Multiple ksft_exit_fail_msg() calls exit the program without closing this file descriptor, and the cleanup_namespace() function registered with atexit() also doesn't close it.

2026-07-31KVM: arm64: selftests: Add stage-2 block transition testFuad Tabba
Add a test for the two stage-2 granularity changes dirty logging forces at fault time, asserting the guest completes with no KVM_RUN error. The first scenario collapses a page into a hugetlb-backed block: it writes under logging, re-write-protects the page via GET_DIRTY_LOG, then writes again with logging off. The second splits blocks: it faults in several non-executable 2M blocks, enables logging, then executes in each block so an execute permission fault splits it. It is skipped when CTR_EL0.DIC is set, since mappings are then executable and no execute fault occurs. Both paths make the fault handler allocate under mmu_lock, so a backend that fails to stage that memory returns a KVM_RUN error or crashes the host. The property holds on any host. On a pKVM host, where a non-protected guest uses the pkvm_pgtable_*() backend, it also guards that backend's fault-time staging.

2026-07-30KVM: arm64: Expose PMMIR_EL1.SLOTS under strict PMUv3 UAPICongkai Tan
Introduce a new field pmmir_slots in struct kvm_arch to store PMMIR_EL1.SLOTS. It only saves the actual hardware PMU value when the VMM explicitly selects a PMU under KVM_ARM_VCPU_PMU_V3_STRICT. Otherwise, it stays 0 after allocation. Use this field to implement guest access, userspace get, and userspace set for PMMIR_EL1: - access_pmmir(): uses the value in kvm->arch.pmmir_slots directly. If the VMM selected a PMU and KVM_ARM_VCPU_PMU_V3_STRICT is set, the guest can correctly read the underlying core's SLOTS. Otherwise, it continues to read 0 since the true SLOTS value can be nondeterministic. - get_pmmir(): same as access_pmmir(). - set_pmmir(): only the SLOTS field is writable; a value setting any other bit is rejected with -EINVAL, since get_pmmir() returns SLOTS zero-extended. A value of 0 resets kvm->arch.pmmir_slots to 0 for backward compatibility, as the register is RAZ in older KVM, a value matching the current SLOTS is accepted as a no-op, and anything else is rejected with -EINVAL. Once the VM has run PMMIR_EL1 is immutable, so a mismatching write then returns -EBUSY. The register is now exposed via KVM_GET_REG_LIST for PMUv3 vCPUs, so add it to the get-reg-list selftest's PMU register list.

2026-07-30selftests/mm/uffd: don't treat UFFDIO_COPY -ENOENT as a failureMike Rapoport (Microsoft)
Non-cooperarive uffd events are inherently racy and can happen in parallel with other userfaultfd operations. During event tests in uffd-unit-tests, the uffd monitor calls UFFDIO_UNREGISTER upon receiving UFFD_EVENT_REMOVE. In parallel, the faulting_process() verifies that the removed memory is actually zeroed. If a verification read wins the race with UFFDIO_UNREGISTER, it causes a missing fault that uffd monitor would receive after UFFDIO_UNREGISTER is complete. The monitor resolves the fault using UFFDIO_COPY that fails with -ENOENT which means that VMA has been changed (see commit 27d02568f529 ("userfaultfd: mcopy_atomic: return -ENOENT when no compatible VMA found")). Treat -ENOENT returned by UFFDIO_COPY as non-fatal, the same way -EEXIST is treated for concurrent faults, and don't fail the test.

Passing a stack-local child_pid to clone() with CLONE_CHILD_CLEARTID is unsafe: the kernel clears that address when the child exits, which may happen after the test function has returned and the stack slot has been reused. Neither testcase uses the settid/cleartid pointers for synchronization. Drop CLONE_PARENT_SETTID and CLONE_CHILD_CLEARTID and pass NULL for the clone tid arguments. Wait for the clone child to exit via tkill in test_sigsegv_handler_with_different_pkey_for_stack(), matching test_pkru_sigreturn(), so the detached thread cannot overlap with the next testcase.

2026-07-30selftests: net: add coverage for fdb nexthop dst_portJack Ma
Add coverage for the new per-nexthop VXLAN destination port (NHA_DST_PORT). In fib_nexthops.sh, new ipv4_fdb_port_fcnal() and ipv6_fdb_port_fcnal() tests check that a dst_port is accepted on an fdb nexthop that has a gateway and echoed back on dump, that it is rejected without a gateway and rejected when zero, that a group may hold legs that differ only in UDP port, and that a portless fdb nexthop omits the attribute. The tests SKIP when iproute2 lacks the "dst_port" keyword. In test_vxlan_nh.sh, basic_tx_common() gains a second fdb nexthop group whose nexthop carries a destination port that differs from the VXLAN device default, plus a flower filter keyed on that port, to confirm the per-nexthop port is used on the wire. The test now requires an iproute2 with dst_port support.

2026-07-29KVM: selftests: Trigger L2->L1 exits stress save+restore and #PF testYosry Ahmed
Extend the testing coverage in L2 by forcing a nested VM-Exit from L2 to L1 right after restore on every other iteration. Forcing a nested VM-Exit while L0 has control (e.g. without explicitly running L2 and making a hypercall) is valuable, as it often happens during live migration (e.g. L1 timer interrupt fires by the time the VM lands on the destination). To force the nested VM-Exit inject a #UD in to the saved vCPU state, and intercept #UD from L1. With this change, the test reliably reproduces the CR2 bug fixed by commit 5c247d08bc81 ("KVM: nSVM: Use vcpu->arch.cr2 when updating vmcb12 on nested #VMEXIT") -- at least on Milan, Genoa, and Turin CPUs.

Instead of an explicit GUEST_SYNC() after each access+#PF, run another thread that keeps sending SIGUSR to the vCPU thread, essentially triggering exits to userspace and save+restore on random points in guest execution. This makes the test a lot more meaningful as it opens the door to exercising race conditions between #PF handling in the guest and save+restore in the host. The signals are ignored using SIG_IGN outside of __vcpu_run() to avoid interrupting other ioctls/sysctls performed by the test.

2026-07-29KVM: selftests: Add basic stress test for save+restore and #PF handlingYosry Ahmed
Add a basic stress test for handling #PFs in a guest while the host is doing save+restore cycles. The guest periodically accesses non-present memory causing a #PF, and the #PF handler walks the page tables and updates the PTE to be present, like a proper #PF handler. After every access (and #PF), the guest triggers a sync and the test performs save+restore of the VM. This is not very meaningful as save+restore are performed after the access and #PF handling complete, but following changes will change that.

2026-07-29KVM: selftests: Do not intercept #PF by default in nVMX testsYosry Ahmed
init_vmcs_control_fields() sets PFEC_MASK and PFEC_MATCH so that they never match, which reverses the meaning of the PF_VECTOR bit in EXCEPTION_BITMAP (which is zeroed), effectively enabling #PF interception by default. The relevant part of the SDM describes this: When a page fault occurs, a processor consults (1) bit 14 of the exception bitmap; (2) the error code produced with the page fault [PFEC]; (3) the page-fault error-code mask field [PFEC_MASK]; and (4) the page-fault error-code match field [PFEC_MATCH]. It checks if PFEC & PFEC_MASK = PFEC_MATCH. If there is equality, the specification of bit 14 in the exception bitmap is followed (for example, a VM exit occurs if that bit is set). If there is inequality, the meaning of that bit is reversed (for example, a VM exit occurs if that bit is clear). Clear PFEC_MATCH such that there is equality, and the #PF bit in the exception bitmap is followed, so that #PFs are not intercepted by default, same as every other exception. This also allows tests to set the #PF bit in the exception bitmap if they want to intercept #PFs, without having to muck with the PFEC_{MASK,MATCH} fields.

2026-07-29KVM: selftests: Reuse GPR switching logic for nVMXYosry Ahmed
Reuse the GPR switching logic for nVMX by defining VMX_SWITCH_GPRS_ASM, which is essentially the same as SVM_SWITCH_GPRS_ASM but also switches RAX and doesn't switch RFLAGS, replacing the push/pop of a subset of the registers. The long clobber list of registers is no longer needed as registers are saved and restored appropriately (and not clobbered by L2). Define VMX_SWITCH_GPRS_ASM before including evmcs.h, such that it can be used by evmcs_vmlaunch() and evmcs_vmresume(). This replaces the apparently thread-safe push/pop sequence with the global GPR switching logic used by SVM, which isn't thread-safe at all. However this is still an improvement because: - The VMX logic is half-baked and prompts the UCALL clobber hack as it doesn't properly save/restore everything. Reusing the GPR switching logic used by SVM allows for dropping that hack. - Hitting a problem due to half-baked GPR save/restore logic is arguably more likely than thread-safety. Evidently, adding more involved stress tests fails on VMX with the existing push/pop sequence. OTOH, there are no known failures on SVM due to lack of thread-safety fo save/restore. Only one test currently uses more than one vCPU with nested (the memstress test). The logical next step is to move the guest_regs to be per-vCPU, making it thread-safe for both VMX and SVM in a proper way.

2026-07-29KVM: selftests: Rework GPR registers switching for SVM (and fix offsets)Yosry Ahmed
The assembly code defined by SAVE_GPR_C uses the wrong offsets for some registers in guest_regs. For example, the offset of RCX should be 0x08 not 0x10. Also, the last offset in the struct (R15) is 0x78, not 0x80, so the code actually saves and restore beyond the end of gpr64_regs. Eliminate hardcoded offsets by dynamically generating offsets using offset_of() and using macros to pass the offsets to assembly as asm constraints. To avoid register conflicts in inline assembly (since almost all GPRs are context-switched), access guest_regs via absolute symbol addressing (guest_regs + offset) rather than using a base register which could get overwritten mid-assembly. While at it, rename SAVE_GPR_C and LOAD_GPR_C to a single macro, SVM_SWITCH_GPRS_ASM, rename gpr64_regs to guest_regs, and expose it in processor.h (in preparation for reusing it for VMX).

2026-07-29KVM: selftests: Fix RAX and RFLAGS VMCB offsets when running L2Yosry Ahmed
The offsets used (0x170 and 0x1f8) are offsets within vmcb_save_area, not vmcb. The correct offsets should include the base of vmcb_save_area within vmcb (which is 0x400 -- so 0x570 and 0x5f8). Instead of just correcting the offsets, use vmcb->save.rax and vmcb->save.rflags as parameters to the asm block and avoid hardcoding offsets completely. While at it, also use guest_regs.rax directly instead of assuming it's at offset 0 of guest_regs. Note: "+m" must be used for vmcb_rax and vmcb_rflags, as caching those fields in registers would be wrong as the underlying KVM will update them in memory. The same problem was recently fixed (differently) for kvm-unit-tests [1].
