## Description

In the Linux kernel, the following vulnerability has been resolved:  KVM: Don't clobber irqfd routing type when deassigning irqfd  When deassigning a KVM_IRQFD, don't clobber the irqfd's copy of the IRQ's routing entry as doing so breaks kvm_arch_irq_bypass_del_producer() on x86 and arm64, which explicitly look for KVM_IRQ_ROUTING_MSI.  Instead, to handle a concurrent routing update, verify that the irqfd is still active before consuming the routing information.  As evidenced by the x86 and arm64 bugs, and another bug in kvm_arch_update_irqfd_routing() (see below), clobbering the entry type without notifying arch code is surprising and error prone.  As a bonus, checking that the irqfd is active provides a convenient location for documenting _why_ KVM must not consume the routing entry for an irqfd that is in the process of being deassigned: once the irqfd is deleted from the list (which happens *before* the eventfd is detached), it will no longer receive updates via kvm_irq_routing_update(), and so KVM could deliver an event using stale routing information (relative to KVM_SET_GSI_ROUTING returning to userspace).  As an even better bonus, explicitly checking for the irqfd being active fixes a similar bug to the one the clobbering is trying to prevent: if an irqfd is deactivated, and then its routing is changed, kvm_irq_routing_update() won't invoke kvm_arch_update_irqfd_routing() (because the irqfd isn't in the list).  And so if the irqfd is in bypass mode, IRQs will continue to be posted using the old routing information.  As for kvm_arch_irq_bypass_del_producer(), clobbering the routing type results in KVM incorrectly keeping the IRQ in bypass mode, which is especially problematic on AMD as KVM tracks IRQs that are being posted to a vCPU in a list whose lifetime is tied to the irqfd.  Without the help of KASAN to detect use-after-free, the most common sympton on AMD is a NULL pointer deref in amd_iommu_update_ga() due to the memory for irqfd structure being re-allocated and zeroed, resulting in irqfd->irq_bypass_data being NULL when read by avic_update_iommu_vcpu_affinity():    BUG: kernel NULL pointer dereference, address: 0000000000000018   #PF: supervisor read access in kernel mode   #PF: error_code(0x0000) - not-present page   PGD 40cf2b9067 P4D 40cf2b9067 PUD 408362a067 PMD 0   Oops: Oops: 0000 [#1] SMP   CPU: 6 UID: 0 PID: 40383 Comm: vfio_irq_test   Tainted: G     U  W  O        6.19.0-smp--5dddc257e6b2-irqfd #31 NONE   Tainted: [U]=USER, [W]=WARN, [O]=OOT_MODULE   Hardware name: Google, Inc.
