And any additional attempt to request device hot-unplug afterwards results in following error: "Device XYZ is already in the process of unplug" arguably it can be considered as a regression introduced by [2], before which it was possible to issue unplug request multiple times. Accept new uplug requests after timeout (1ms). This brings ACPI PCI hotplug on par with native PCIe unplug behavior [1] and allows user to repeat unplug requests at propper times. Set expire timeout to arbitrary 1msec so user won't be able to flood guest with SCI interrupts by calling device_del in tight loop. PS: ACPI spec doesn't mandate what OSPM can do with GPEx.status bits set before it's booted => it's impl. depended. Status bits may be retained (I tested with one Windows version) or cleared (Linux since 2.6 kernel times) during guest's ACPI subsystem initialization. Clearing status bits (though not wrong per se) hides the unplug event from guest, and it's upto user to repeat device_del later when guest is able to handle unplug requests. 1) 18416c62e3 ("pcie: expire pending delete") 2) Fixes: cce8944cc9ef ("qdev-monitor: Forbid repeated device_del") Signed-off-by: Igor Mammedov <imammedo@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> CC: mst@redhat.com CC: anisinha@redhat.com CC: jusual@redhat.com CC: kraxel@redhat.com Message-Id: <20230418090449.2155757-1-imammedo@redhat.com> Reviewed-by: Michael S.

There are other complex cases though where the back-end needs more information and simple mmap() isn't enough. For example Xen, a type-1 hypervisor, currently supports memory mapping via two different methods, foreign-mapping (via /dev/privcmd) and grant-dev (via /dev/gntdev). In both these cases, the back-end needs to call mmap() and ioctl(), with extra information like the Xen domain-id of the guest whose memory we are trying to map. Add a new protocol feature, 'VHOST_USER_PROTOCOL_F_XEN_MMAP', which lets the back-end know about the additional memory mapping requirements. When this feature is negotiated, the front-end will send the additional information within the memory regions themselves.

| * | | virtio: refresh vring region cache after updating a virtqueue sizeCarlos López2023-04-215-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a virtqueue size is changed by the guest via virtio_queue_set_num(), its region cache is not automatically updated. If the size was increased, this could lead to accessing the cache out of bounds. For example, in vring_get_used_event(): static inline uint16_t vring_get_used_event(VirtQueue *vq) { return vring_avail_ring(vq, vq->vring.num); } static inline uint16_t vring_avail_ring(VirtQueue *vq, int i) { VRingMemoryRegionCaches *caches = vring_get_region_caches(vq); hwaddr pa = offsetof(VRingAvail, ring[i]); if (!caches) { return 0; } return virtio_lduw_phys_cached(vq->vdev, &caches->avail, pa); } vq->vring.num will be greater than caches->avail.len, which will trigger a failed assertion down the call path of virtio_lduw_phys_cached(). Fix this by calling virtio_init_region_cache() after virtio_queue_set_num() if we are not already calling virtio_queue_set_rings(). In the legacy path this is already done by virtio_queue_update_rings().
