During shutdown the IOAPIC trigger mode is reset to edge triggered while the vfio-pci INTx is still registered with a resampler. This allows us to get into an infinite loop: ioapic_set_irq -> ioapic_lazy_update_eoi -> kvm_ioapic_update_eoi_one -> kvm_notify_acked_irq -> kvm_notify_acked_gsi -> (via irq_acked fn ptr) irqfd_resampler_ack -> kvm_set_irq -> (via set fn ptr) kvm_set_ioapic_irq -> kvm_ioapic_set_irq -> ioapic_set_irq Commit 8be8f932 ("kvm: ioapic: Restrict lazy EOI update to edge-triggered interrupts", 2020-05-04) acknowledges that this recursion loop exists and tries to avoid it at the call to ioapic_lazy_update_eoi, but at this point the scenario is already set, we have an edge interrupt with resampler on the same gsi. Fortunately, the only user of irq ack notifiers (in addition to resamplefd) is i8254 timer interrupt reinjection. These are edge-triggered, so in principle they would need the call to kvm_ioapic_update_eoi_one from ioapic_lazy_update_eoi, but they already disable AVIC(*), so they don't need the lazy EOI behavior. Therefore, remove the call to kvm_ioapic_update_eoi_one from ioapic_lazy_update_eoi. This fixes CVE-2020-27152. Note that this issue cannot happen with SR-IOV assigned devices because virtual functions do not have INTx, only MSI. Fixes: f458d039 ("kvm: ioapic: Lazy update IOAPIC EOI") Suggested-by:

Quoting https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html: You can define a local register variable and associate it with a specified register... The only supported use for this feature is to specify registers for input and output operands when calling Extended asm (see Extended Asm). This may be necessary if the constraints for a particular machine don't provide sufficient control to select the desired register. On 32-bit x86, this is used to ensure that gcc will put an 8-byte value into the %edx:%eax pair, while all other cases will just use the single register %eax (%rax on x86-64). While the _ASM_AX actually just expands to "%eax", note this comment next to get_user() which does something very similar: * The use of _ASM_DX as the register specifier is a bit of a * simplification, as gcc only cares about it as the starting point * and not size: for a 64-bit value it will use %ecx:%edx on 32 bits * (%ecx being the next register in gcc's x86 register sequence), and * %rdx on 64 bits. However, getting this to work requires that there is no code between the assignment to the local register variable and its use as an input to the asm() which can possibly clobber any of the registers involved - including evaluation of the expressions making up other inputs. In the current code, the ptr expression used directly as an input may cause such code to be emitted. For example, Sean Christopherson observed that with KASAN enabled and ptr being current->set_child_tid (from chedule_tail()), the load of current->set_child_tid causes a call to __asan_load8() to be emitted immediately prior to the __put_user_4 call, and Naresh Kamboju reports that various mmstress tests fail on KASAN-enabled builds. It's also possible to synthesize a broken case without KASAN if one uses "foo()" as the ptr argument, with foo being some "extern u64 __user *foo(void);" (though I don't know if that appears in real code). Fix it by making sure ptr gets evaluated before the assignment to __val_pu, and add a comment that __val_pu must be the last thing computed before the asm() is entered.
