vfio/pci: Fix ordering of eventfd vs virqfd shutdown Both the INTx and MSI/X disable paths do an eventfd_ctx_put() for the trigger eventfd before calling vfio_virqfd_disable() any potential mask and unmask eventfds. This opens a use-after-free race where an inopportune irqfd can reference the freed signalling eventfd. Reorder to avoid this possibility. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
