2020-11-01vfio: Add load state functions to SaveVMHandlersKirti Wankhede2-0/+199
Sequence during _RESUMING device state: While data for this device is available, repeat below steps: a. read data_offset from where user application should write data. b. write data of data_size to migration region from data_offset. c. write data_size which indicates vendor driver that data is written in staging buffer. For user, data is opaque. User should write data in the same order as received.

2020-11-01vfio: Add save state functions to SaveVMHandlersKirti Wankhede3-0/+283
Added .save_live_pending, .save_live_iterate and .save_live_complete_precopy functions. These functions handles pre-copy and stop-and-copy phase. In _SAVING|_RUNNING device state or pre-copy phase: - read pending_bytes. If pending_bytes > 0, go through below steps. - read data_offset - indicates kernel driver to write data to staging buffer. - read data_size - amount of data in bytes written by vendor driver in migration region. - read data_size bytes of data from data_offset in the migration region. - Write data packet to file stream as below: {VFIO_MIG_FLAG_DEV_DATA_STATE, data_size, actual data, VFIO_MIG_FLAG_END_OF_STATE } In _SAVING device state or stop-and-copy phase a. read config space of device and save to migration file stream. This doesn't need to be from vendor driver. Any other special config state from driver can be saved as data in following iteration. b. read pending_bytes. If pending_bytes > 0, go through below steps. c. read data_offset - indicates kernel driver to write data to staging buffer. d. read data_size - amount of data in bytes written by vendor driver in migration region. e. read data_size bytes of data from data_offset in the migration region. f. Write data packet as below: {VFIO_MIG_FLAG_DEV_DATA_STATE, data_size, actual data} g. iterate through steps b to f while (pending_bytes > 0) h. Write {VFIO_MIG_FLAG_END_OF_STATE} When data region is mapped, its user's responsibility to read data from data_offset of data_size before moving to next steps. Added fix suggested by Artem Polyakov to reset pending_bytes in vfio_save_iterate(). Added fix suggested by Zhi Wang to add 0 as data size in migration stream and add END_OF_STATE delimiter to indicate phase complete.

2020-11-01vfio: Register SaveVMHandlers for VFIO deviceKirti Wankhede2-0/+104
Define flags to be used as delimiter in migration stream for VFIO devices. Added .save_setup and .save_cleanup functions. Map & unmap migration region from these functions at source during saving or pre-copy phase. Set VFIO device state depending on VM's state. During live migration, VM is running when .save_setup is called, _SAVING | _RUNNING state is set for VFIO device. During save-restore, VM is paused, _SAVING state is set for VFIO device.

2020-10-30virtio: skip guest index check on device loadFelipe Franciosi1-6/+7
QEMU must be careful when loading device state off migration streams to prevent a malicious source from exploiting the emulator. Overdoing these checks has the side effect of allowing a guest to "pin itself" in cloud environments by messing with state which is entirely in its control. Similarly to what f3081539 achieved in usb_device_post_load(), this commit removes such a check from virtio_load(). Worth noting, the result of a load without this check is the same as if a guest enables a VQ with invalid indexes to begin with. That is, the virtual device is set in a broken state (by the datapath handler) and must be reset.

After Linux kernel commit 61363c1474b1 ("iommu/vt-d: Enable ATS only if the device uses page aligned address."), ATS will be only enabled if device advertises a page aligned request. Unfortunately, vhost-net is the only user and we don't advertise the aligned request capability in the past since both vhost IOTLB and address_space_get_iotlb_entry() can support non page aligned request. Though it's not clear that if the above kernel commit makes sense. Let's advertise a page aligned ATS here to make vhost device IOTLB work with Intel IOMMU again.

2020-10-30vhost: Don't special case vq->used_phys in vhost_get_log_size()Greg Kurz1-10/+0
The first loop in vhost_get_log_size() computes the size of the dirty log bitmap so that it allows to track changes in the entire guest memory, in terms of GPA. When not using a vIOMMU, the address of the vring's used structure, vq->used_phys, is a GPA. It is thus already covered by the first loop. When using a vIOMMU, vq->used_phys is a GIOVA that will be translated to an HVA when the vhost backend needs to update the used structure. It will log the corresponding GPAs into the bitmap but it certainly won't log the GIOVA. So in any case, vq->used_phys shouldn't be explicitly used to size the bitmap. Drop the second loop. This fixes a crash of the source when migrating a guest using in-kernel vhost-net and iommu_platform=on on POWER, because DMA regions are put over 0x800000000000000ULL. The resulting insanely huge log size causes g_malloc0() to abort.

Prevent _CRS resources being quietly chopped off and instead throw an assertion. _CRS is used by host bridges to declare regions of io and/or memory that they consume. On some (all?) platforms the host bridge doesn't have PCI header space and so they need some way to convey the information.

2020-10-30vhost-vsock: set vhostfd to non-blocking modeStefano Garzarella1-0/+10
vhost IOTLB API uses read()/write() to exchange iotlb messages with the kernel module. The QEMU implementation expects a non-blocking fd, indeed commit c471ad0e9b ("vhost_net: device IOTLB support") set it for vhost-net. Without this patch, if we enable iommu for the vhost-vsock device, QEMU can hang when exchanging IOTLB messages. As commit 894022e616 ("net: check if the file descriptor is valid before using it") did for tap, let's use qemu_try_set_nonblock() when fd is provided by the user.

Reporting "Failed to connect socket" is essentially useless for a user attempting to diagnose failure. It needs to include the target address details. Similarly when failing to create a socket we should include the socket family info, so the user understands what particular feature was missing in their kernel build (IPv6, VSock in particular).
