2021-11-02esp: ensure in-flight SCSI requests are always cancelledMark Cave-Ayland1-5/+5
There is currently a check in esp_select() to cancel any in-flight SCSI requests to ensure that issuing multiple select commands without continuing through the rest of the ESP state machine ignores all but the last SCSI request. This is also enforced through the addition of assert()s in esp_transfer_data() and scsi_read_data(). The get_cmd() function does not call esp_select() when TC == 0 which means it is possible for a fuzzer to trigger these assert()s by sending a select command when TC == 0 immediately after a valid SCSI CDB has been submitted. Since esp_select() is only called from get_cmd(), hoist the check to cancel in-flight SCSI requests from esp_select() into get_cmd() to ensure it is always called when executing a select command to initiate a new SCSI request.

2021-11-02ide: Cap LBA28 capacity announcement to 2^28-1Samuel Thibault1-2/+6
The LBA28 capacity (at offsets 60/61 of identification) is supposed to express the maximum size supported by LBA28 commands. If the device is larger than this, we have to cap it to 2^28-1. At least NetBSD happens to be using this value to determine whether to use LBA28 or LBA48 for its commands, using LBA28 for sectors that don't need LBA48. This commit thus fixes NetBSD access to disks larger than 128GiB.

Allow instantiating a virtio-iommu device by adding an ACPI Virtual I/O Translation table (VIOT), which describes the relation between the virtio-iommu and the endpoints it manages. Add a hotplug handler for virtio-iommu on x86 and set the necessary reserved region property. On x86, the [0xfee00000, 0xfeefffff] DMA region is reserved for MSIs. DMA transactions to this range either trigger IRQ remapping in the IOMMU or bypasses IOMMU translation. Although virtio-iommu does not support IRQ remapping it must be informed of the reserved region so that it can forward DMA transactions targeting this region.

We're about to support a third vIOMMU for x86, virtio-iommu which doesn't inherit X86IOMMUState. Move the IOMMU singleton into PCMachineState, so it can be shared between all three vIOMMUs. The x86_iommu_get_default() helper is still needed by KVM and IOAPIC to fetch the default IRQ-remapping IOMMU. Since virtio-iommu doesn't support IRQ remapping, this interface doesn't need to change for the moment. We could later replace X86IOMMUState with an "IRQ remapping IOMMU" interface if necessary.

Similar to VFIO, vDPA will go ahead an map+pin all guest memory. Memory that used to be discarded will get re-populated and if we discard+re-access memory after mapping+pinning, the pages mapped into the vDPA IOMMU will go out of sync with the actual pages mapped into the user space page tables. Set discarding of RAM broken such that: - virtio-mem and vhost-vdpa run mutually exclusive - virtio-balloon is inhibited and no memory discards will get issued In the future, we might be able to support coordinated discarding of RAM as used by virtio-mem and already supported by vfio via the RamDiscardManager.

Now that we check sysbus device types during device creation, we can remove the check in the machine init done notifier. This was the only thing done by this notifier, so we remove the whole sysbus_notifier structure of the MachineState. Note: This notifier was checking all /peripheral and /peripheral-anon sysbus devices. Now we only check those added by -device cli option or device_add qmp command when handling the command/option. So if there are some devices added in one of these containers manually (eg in machine C code), these will not be checked anymore. This use case does not seem to appear apart from hw/xen/xen-legacy-backend.c (it uses qdev_set_id() and in this case, not for a sysbus device, so it's ok).
