From: Jack Wang <jinpu.wang(a)cloud.ionos.com> During backport f7eea636c3d5 ("KVM: nVMX: handle page fault in vmread"), there was a mistake the exception reference should be passed to function kvm_write_guest_virt_system, instead of NULL, other wise, we will get NULL pointer deref, eg kvm-unit-test triggered a NULL pointer deref below: [ 948.518437] kvm [24114]: vcpu0, guest rIP: 0x407ef9 kvm_set_msr_common: MSR_IA32_DEBUGCTLMSR 0x3, nop [ 949.106464] BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 [ 949.106707] PGD 0 P4D 0 [ 949.106872] Oops: 0002 [#1] SMP [ 949.107038] CPU: 2 PID: 24126 Comm: qemu-2.7 Not tainted 4.19.77-pserver #4.19.77-1+feature+daily+update+20191005.1625+a4168bb~deb9 [ 949.107283] Hardware name: Dell Inc.

In reality, bits 31:16 must be zero, i.e. error codes are 16-bit values. The bogus error code check manifests as an unexpected VM-Entry failure due to an invalid code field (error number 7) in L1, e.g. when injecting a #GP with error_code=0x9f00. Nadav previously reported the bug[*], both to KVM and Intel, and fixed the associated kvm-unit-test.

When freeing the queues, we check for possible escalation interrupts and free them also. But when a XIVE VP is disabled, the underlying XIVE ENDs also are disabled in OPAL. When an END (Event Notification Descriptor) is disabled, its ESB pages (ESn and ESe) are disabled and loads return all 1s. Which means that any access on the ESB page of the escalation interrupt will return invalid values. When an interrupt is freed, the shutdown handler computes a 'saved_p' field from the value returned by a load in xive_do_source_set_mask(). This value is incorrect for escalation interrupts for the reason described above. This has no impact on Linux/KVM today because we don't make use of it but we will introduce in future changes a xive_get_irqchip_state() handler. This handler will use the 'saved_p' field to return the state of an interrupt and 'saved_p' being incorrect, softlockup will occur. Fix the vCPU cleanup sequence by first freeing the escalation interrupts if any, then disable the XIVE VP and last free the queues.
