Re-check sp->nx_huge_page_disallowed under the tdp_mmu_pages_lock spinlock when adding a new shadow page in the TDP MMU. To ensure the NX reclaim kthread can't see a not-yet-linked shadow page, the page fault path links the new page table prior to adding the page to possible_nx_huge_pages. If the page is zapped by different task, e.g. because dirty logging is disabled, between linking the page and adding it to the list, KVM can end up triggering use-after-free by adding the zapped SP to the aforementioned list, as the zapped SP's memory is scheduled for removal via RCU callback. The bug is detected by the sanity checks guarded by CONFIG_DEBUG_LIST=y, i.e. the below splat is just one possible signature. ------------[ cut here ]------------ list_add corruption. prev->next should be next (ffffc9000071fa70), but was ffff88811125ee38.

Map the leaf SPTE when handling a TDP MMU page fault if and only if the target level is reached. A recent commit reworked the retry logic and incorrectly assumed that walking SPTEs would never "fail", as the loop either bails (retries) or installs parent SPs. However, the iterator itself will bail early if it detects a frozen (REMOVED) SPTE when stepping down. The TDP iterator also rereads the current SPTE before stepping down specifically to avoid walking into a part of the tree that is being removed, which means it's possible to terminate the loop without the guts of the loop observing the frozen SPTE, e.g. if a different task zaps a parent SPTE between the initial read and try_step_down()'s refresh. Mapping a leaf SPTE at the wrong level results in all kinds of badness as page table walkers interpret the SPTE as a page table, not a leaf, and walk into the weeds. ------------[ cut here ]------------ WARNING: CPU: 1 PID: 1025 at arch/x86/kvm/mmu/tdp_mmu.c:1070 kvm_tdp_mmu_map+0x481/0x510 Modules linked in: kvm_intel CPU: 1 PID: 1025 Comm: nx_huge_pages_t Tainted: G W 6.1.0-rc4+ #64 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:kvm_tdp_mmu_map+0x481/0x510 RSP: 0018:ffffc9000072fba8 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffffc9000072fcc0 RCX: 0000000000000027 RDX: 0000000000000027 RSI: 00000000ffffdfff RDI: ffff888277c5b4c8 RBP: ffff888107d45a10 R08: ffff888277c5b4c0 R09: ffffc9000072fa48 R10: 0000000000000001 R11: 0000000000000001 R12: ffffc9000073a0e0 R13: ffff88810fc54800 R14: ffff888107d1ae60 R15: ffff88810fc54f90 FS: 00007fba9f853740(0000) GS:ffff888277c40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000010aa7a003 CR4: 0000000000172ea0 Call Trace: <TASK> kvm_tdp_page_fault+0x10c/0x130 kvm_mmu_page_fault+0x103/0x680 vmx_handle_exit+0x132/0x5a0 [kvm_intel] vcpu_enter_guest+0x60c/0x16f0 kvm_arch_vcpu_ioctl_run+0x1e2/0x9d0 kvm_vcpu_ioctl+0x271/0x660 __x64_sys_ioctl+0x80/0xb0 do_syscall_64+0x2b/0x50 entry_SYSCALL_64_after_hwframe+0x46/0xb0 </TASK> ---[ end trace 0000000000000000 ]--- Invalid SPTE change: cannot replace a present leaf SPTE with another present leaf SPTE mapping a different PFN! as_id: 0 gfn: 100200 old_spte: 600000112400bf3 new_spte: 6000001126009f3 level: 2 ------------[ cut here ]------------ kernel BUG at arch/x86/kvm/mmu/tdp_mmu.c:559! invalid opcode: 0000 [#1] SMP CPU: 1 PID: 1025 Comm: nx_huge_pages_t Tainted: G W 6.1.0-rc4+ #64 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:__handle_changed_spte.cold+0x95/0x9c RSP: 0018:ffffc9000072faf8 EFLAGS: 00010246 RAX: 00000000000000c1 RBX: ffffc90000731000 RCX: 0000000000000027 RDX: 0000000000000000 RSI: 00000000ffffdfff RDI: ffff888277c5b4c8 RBP: 0600000112400bf3 R08: ffff888277c5b4c0 R09: ffffc9000072f9a0 R10: 0000000000000001 R11: 0000000000000001 R12: 06000001126009f3 R13: 0000000000000002 R14: 0000000012600901 R15: 0000000012400b01 FS: 00007fba9f853740(0000) GS:ffff888277c40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000010aa7a003 CR4: 0000000000172ea0 Call Trace: <TASK> kvm_tdp_mmu_map+0x3b0/0x510 kvm_tdp_page_fault+0x10c/0x130 kvm_mmu_page_fault+0x103/0x680 vmx_handle_exit+0x132/0x5a0 [kvm_intel] vcpu_enter_guest+0x60c/0x16f0 kvm_arch_vcpu_ioctl_run+0x1e2/0x9d0 kvm_vcpu_ioctl+0x271/0x660 __x64_sys_ioctl+0x80/0xb0 do_syscall_64+0x2b/0x50 entry_SYSCALL_64_after_hwframe+0x46/0xb0 </TASK> Modules linked in: kvm_intel ---[ end trace 0000000000000000 ]--- Fixes: 63d28a25 ("KVM: x86/mmu: simplify kvm_tdp_mmu_map flow when guest has to retry") Cc: Robert Hoo <robert.hu@linux.intel.com> Signed-off-by:

When stuffing the allowed secondary execution controls for nested VMX in response to CPUID updates, don't set the allowed-1 bit for a feature that isn't supported by KVM, i.e. isn't allowed by the canonical vmcs_config. WARN if KVM attempts to manipulate a feature that isn't supported. All features that are currently stuffed are always advertised to L1 for nested VMX if they are supported in KVM's base configuration, and no additional features should ever be added to the CPUID-induced stuffing (updating VMX MSRs in response to CPUID updates is a long-standing KVM flaw that is slowly being fixed).

Set ENABLE_USR_WAIT_PAUSE in KVM's supported VMX MSR configuration if the feature is supported in hardware and enabled in KVM's base, non-nested configuration, i.e. expose ENABLE_USR_WAIT_PAUSE to L1 if it's supported. This fixes a bug where saving/restoring, i.e. migrating, a vCPU will fail if WAITPKG (the associated CPUID feature) is enabled for the vCPU, and obviously allows L1 to enable the feature for L2. KVM already effectively exposes ENABLE_USR_WAIT_PAUSE to L1 by stuffing the allowed-1 control ina vCPU's virtual MSR_IA32_VMX_PROCBASED_CTLS2 when updating secondary controls in response to KVM_SET_CPUID(2), but (a) that depends on flawed code (KVM shouldn't touch VMX MSRs in response to CPUID updates) and (b) runs afoul of vmx_restore_control_msr()'s restriction that the guest value must be a strict subset of the supported host value. Although no past commit explicitly enabled nested support for WAITPKG, doing so is safe and functionally correct from an architectural perspective as no additional KVM support is needed to virtualize TPAUSE, UMONITOR, and UMWAIT for L2 relative to L1, and KVM already forwards VM-Exits to L1 as necessary (commit bf653b78, "KVM: vmx: Introduce handle_unexpected_vmexit and handle WAITPKG vmexit"). Note, KVM always keeps the hosts MSR_IA32_UMWAIT_CONTROL resident in hardware, i.e. always runs both L1 and L2 with the host's power management settings for TPAUSE and UMWAIT. See commit bf09fb6c ("KVM: VMX: Stop context switching MSR_IA32_UMWAIT_CONTROL") for more details.

Explicitly drop the result of kvm_vcpu_write_guest() when writing the "launch state" as part of VMCLEAR emulation, and add a comment to call out that KVM's behavior is architecturally valid. Intel's pseudocode effectively says that VMCLEAR is a nop if the target VMCS address isn't in memory, e.g. if the address points at MMIO. Add a FIXME to call out that suppressing failures on __copy_to_user() is wrong, as memory (a memslot) does exist in that case. Punt the issue to the future as open coding kvm_vcpu_write_guest() just to make sure the guest dies with -EFAULT isn't worth the extra complexity. The flaw will need to be addressed if KVM ever does something intelligent on uaccess failures, e.g. to support post-copy demand paging, but in that case KVM will need a more thorough overhaul, i.e. VMCLEAR shouldn't need to open code a core KVM helper. No functional change intended. Reported-by:

If a memory failure happens during a direct guest physical memory access, e.g. for nested VMX, KVM hardcodes the failure to X86EMUL_IO_NEEDED and doesn't provide an exception pointer (because the exception struct would just be filled with garbage).

In kvm_hv_flush_tlb(), 'data_offset' and 'consumed_xmm_halves' variables are used in a mutually exclusive way: in 'hc->fast' we count in 'XMM halves' and increase 'data_offset' otherwise. Coverity discovered, that in one case both variables are incremented unconditionally. This doesn't seem to cause any issues as the only user of 'data_offset'/'consumed_xmm_halves' data is kvm_hv_get_tlb_flush_entries() -> kvm_hv_get_hc_data() which also takes into account 'hc->fast' but is still worth fixing. To make things explicit, put 'data_offset' and 'consumed_xmm_halves' to 'struct kvm_hv_hcall' as a union and use at call sites. This allows to remove explicit 'data_offset'/'consumed_xmm_halves' parameters from kvm_hv_get_hc_data()/kvm_get_sparse_vp_set()/kvm_hv_get_tlb_flush_entries() helpers. Note: 'struct kvm_hv_hcall' is allocated on stack in kvm_hv_hypercall() and is not zeroed, consumers are supposed to initialize the appropriate field if needed. Reported-by:

When scanning userspace I/OAPIC entries, intercept EOI for level-triggered IRQs if the current vCPU has a pending and/or in-service IRQ for the vector in its local API, even if the vCPU doesn't match the new entry's destination. This fixes a race between userspace I/OAPIC reconfiguration and IRQ delivery that results in the vector's bit being left set in the remote IRR due to the eventual EOI not being forwarded to the userspace I/OAPIC. Commit 0fc5a36d ("KVM: x86: ioapic: Fix level-triggered EOI and IOAPIC reconfigure race") fixed the in-kernel IOAPIC, but not the userspace IOAPIC configuration, which has a similar race.

The current vPMU can reuse the same pmc->perf_event for the same hardware event via pmc_pause/resume_counter(), but this optimization does not apply to a portion of the TSX events (e.g., "event=0x3c,in_tx=1, in_tx_cp=1"), where event->attr.sample_period is legally zero at creation, thus making the perf call to perf_event_period() meaningless (no need to adjust sample period in this case), and instead causing such reusable perf_events to be repeatedly released and created. Avoid releasing zero sample_period events by checking is_sampling_event() to follow the previously enable/disable optimization. Signed-off-by:

get_user_mapping_size() uses kvm's pgtable library to walk a user space page table created by the kernel, and in doing so, passes metadata that the library needs, including ia_bits, which defines the size of the input address. For the case where the kernel is compiled for 52 VA bits but runs on HW that does not support LVA, it will fall back to 48 VA bits at runtime. Therefore we must use vabits_actual rather than VA_BITS to get the true address size. This is benign in the current code base because the pgtable library only uses it for error checking.

When a VM reboots itself, the reset process will result in an ioctl(KVM_SET_LAPIC, ...) to disable x2APIC mode and set the xAPIC id of the vCPU to its default value, which is the vCPU id. That will be handled in KVM as follows: kvm_vcpu_ioctl_set_lapic kvm_apic_set_state kvm_lapic_set_base => disable X2APIC mode kvm_apic_state_fixup kvm_lapic_xapic_id_updated kvm_xapic_id(apic) != apic->vcpu->vcpu_id kvm_set_apicv_inhibit(APICV_INHIBIT_REASON_APIC_ID_MODIFIED) memcpy(vcpu->arch.apic->regs, s->regs, sizeof(*s)) => update APIC_ID When kvm_apic_set_state invokes kvm_lapic_set_base to disable x2APIC mode, the old 32-bit x2APIC id is still present rather than the 8-bit xAPIC id. kvm_lapic_xapic_id_updated will set the APICV_INHIBIT_REASON_APIC_ID_MODIFIED bit and disable APICv/x2AVIC. Instead, kvm_lapic_xapic_id_updated must be called after APIC_ID is changed. In fact, this fixes another small issue in the code in that potential changes to a vCPU's xAPIC ID need not be tracked for KVM_GET_LAPIC.
