This fixes a wrong error place in unclosed brace error message - check bounds before writing in __xbc_open_brace(). This fixes to check the array index before setting array, so that the bootconfig can support 16th-depth nested brace correctly - fix snprintf truncation check in xbc_node_compose_key_after().

About a fourth of it is a new selftest, and a couple more changes are large in number of files touched (fixing a -Wflex-array-member-not-at-end compiler warning) or lines changed (reformatting of a table in the API documentation, thanks rST). But who am I kidding---it's a lot of commits and there are a lot of bugs being fixed here, some of them on the nastier side like the RISC-V ones. ARM: - Correctly handle deactivation of interrupts that were activated from LRs. Since EOIcount only denotes deactivation of interrupts that are not present in an LR, start EOIcount deactivation walk *after* the last irq that made it into an LR - Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when pKVM is already enabled -- not only thhis isn't possible (pKVM will reject the call), but it is also useless: this can only happen for a CPU that has already booted once, and the capability will not change - Fix a couple of low-severity bugs in our S2 fault handling path, affecting the recently introduced LS64 handling and the even more esoteric handling of hwpoison in a nested context - Address yet another syzkaller finding in the vgic initialisation, where we would end-up destroying an uninitialised vgic with nasty consequences - Address an annoying case of pKVM failing to boot when some of the memblock regions that the host is faulting in are not page-aligned - Inject some sanity in the NV stage-2 walker by checking the limits against the advertised PA size, and correctly report the resulting faults PPC: - Fix a PPC e500 build error due to a long-standing wart that was exposed by the recent conversion to kmalloc_obj(); rip out all the ugliness that led to the wart RISC-V: - Prevent speculative out-of-bounds access using array_index_nospec() in APLIC interrupt handling, ONE_REG regiser access, AIA CSR access, float register access, and PMU counter access - Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(), kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr() - Fix potential null pointer dereference in kvm_riscv_vcpu_aia_rmw_topei() - Fix off-by-one array access in SBI PMU - Skip THP support check during dirty logging - Fix error code returned for Smstateen and Ssaia ONE_REG interface - Check host Ssaia extension when creating AIA irqchip x86: - Fix cases where CPUID mitigation features were incorrectly marked as available whenever the kernel used scattered feature words for them - Validate _all_ GVAs, rather than just the first GVA, when processing a range of GVAs for Hyper-V's TLB flush hypercalls - Fix a brown paper bug in add_atomic_switch_msr() - Use hlist_for_each_entry_srcu() when traversing mask_notifier_list, to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu - Ensure AVIC VMCB fields are initialized if the VM has an in-kernel local APIC (and AVIC is enabled at the module level) - Update CR8 write interception when AVIC is (de)activated, to fix a bug where the guest can run in perpetuity with the CR8 intercept enabled - Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to allow L1 hypervisors to set FREEZE_IN_SMM. This reverts (by default) an unintentional tightening of userspace ABI in 6.17, and provides some amount of backwards compatibility with hypervisors who want to freeze PMCs on VM-Entry - Validate the VMCS/VMCB on return to a nested guest from SMM, because either userspace or the guest could stash invalid values in memory and trigger the processor's consistency checks Generic: - Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being unnecessary and confusing, triggered compiler warnings due to -Wflex-array-member-not-at-end - Document that vcpu->mutex is take outside of kvm->slots_lock and kvm->slots_arch_lock, which is intentional and desirable despite being rather unintuitive Selftests: - Increase the maximum number of NUMA nodes in the guest_memfd selftest to 64 (from 8)" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (43 commits) KVM: selftests: Verify SEV+ guests can read and write EFER, CR0, CR4, and CR8 Documentation: kvm: fix formatting of the quirks table KVM: x86: clarify leave_smm() return value selftests: kvm: add a test that VMX validates controls on RSM selftests: kvm: extract common functionality out of smm_test.c KVM: SVM: check validity of VMCB controls when returning from SMM KVM: VMX: check validity of VMCS controls when returning from SMM KVM: SVM: Set/clear CR8 write interception when AVIC is (de)activated KVM: SVM: Initialize AVIC VMCB fields if AVIC is enabled with in-kernel APIC KVM: x86: Introduce KVM_X86_QUIRK_VMCS12_ALLOW_FREEZE_IN_SMM KVM: x86: Fix SRCU list traversal in kvm_fire_mask_notifiers() KVM: VMX: Fix a wrong MSR update in add_atomic_switch_msr() KVM: x86: hyper-v: Validate all GVAs during PV TLB flush KVM: x86: synthesize CPUID bits only if CPU capability is set KVM: PPC: e500: Rip out "struct tlbe_ref" KVM: PPC: e500: Fix build error due to using kmalloc_obj() with wrong type KVM: selftests: Increase 'maxnode' for guest_memfd tests KVM: arm64: pkvm: Don't reprobe for ICH_VTR_EL2.TDS on CPU hotplug KVM: arm64: vgic: Pick EOIcount deactivations from AP-list tail KVM: arm64: Remove the redundant ISB in __kvm_at_s1e2() ... 2026-03-15T18:36:11+00:00 Linus Torvalds torvalds@linux-foundation.org 2026-03-15T18:36:11+00:00 urn:sha1:4f3df2e5ea69f5717d2721922aff263c31957548 Pull powerpc fixes from Madhavan Srinivasan: - Fix KUAP warning in VMX usercopy path - Fix lockdep warning during PCI enumeration - Fix to move CMA reservations to arch_mm_preinit - Fix to check current->mm is alive before getting user callchain Thanks to Aboorva Devarajan, Christophe Leroy (CS GROUP), Dan Horák, Nicolin Chen, Nilay Shroff, Qiao Zhao, Ritesh Harjani (IBM), Saket Kumar Bhaskar, Sayali Patil, Shrikanth Hegde, Venkat Rao Bagalkote, and Viktor Malik. * tag 'powerpc-7.0-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/iommu: fix lockdep warning during PCI enumeration powerpc/selftests/copyloops: extend selftest to exercise __copy_tofrom_user_power7_vmx powerpc: fix KUAP warning in VMX usercopy path powerpc, perf: Check that current->mm is alive before getting user callchain powerpc/mem: Move CMA reservations to arch_mm_preinit 2026-03-15T18:26:36+00:00 Linus Torvalds torvalds@linux-foundation.org 2026-03-15T18:26:36+00:00 urn:sha1:13af67f599c9f177ac7ca4442be967a91c9ebae4 Pull x86 fix from Ingo Molnar: "Work around S2RAM hang if the firmware unexpectedly re-enables the x2apic hardware while it was disabled by the kernel.
