bea1935867 vfio: Remove PCI dependency
VFIO-PCI device has its own region naming but eventually it starts from 0
(as well as it suppose for others VFIO device types) so simply use 0
instead of VFIO_PCI_BAR0_REGION_INDEX.
At the same time move PCI-specific checks to helper function for clarity.

TEST=manatee PCI device passthrough boots/works

70a71f8d89 devices: virtio: vhost: fix device initialization race condition
Complete vhost worker queue init before spawning thread routine.

Enabling a virtio devices requires updating the
VIRTIO_CONFIG_S_DRIVER_OK bit, which signifies that the devices is
ready to process the virtio queue. Do this before spawning the worker
thread in order to avoid the situation where a guest VM starts using the
queues before initialization has been completed.

Also make this fix for vhost net and vsock.

a1184822c7 Add vhost-user-fs device
This CL adds a vhost user FS device to crosvm. The implementation
requires the following arguments:

--socket = a path to a unix socket crosvm is going to connect to
--tag = a virtio fs tag to mount within the VM
--shared-dir = path to the shared directory

Optional arguments are:
--uid-map = UID translation from inside the VM to the outside
--gid-map = GID translation from inside the VM to the outside

Example command:
crosvm device fs --socket $HOME/test --tag fs-tag --shared-dir $DIR
crosvm run --vhost-user-fs=$HOME/test:fs-tag ...

BUG=b:179636297

e3364b743a fs: Fix enable_verity() impl
The fsverity_enable_arg struct contains optional pointers to additional
data.  Check for them and try to copy them in if necessary.  This
requires a corresponding kernel change where the fuse driver also
reads the struct and copies the relevant data from the userspace
application.

Steps to test this change:

// Create a test file
head -c 1000000 /dev/urandom > file

// Generate a new certificate and private key:
openssl req -newkey rsa:4096 -nodes -keyout key.pem -x509 -out cert.pem

// Convert the certificate from PEM to DER format:
openssl x509 -in cert.pem -out cert.der -outform der

// Load the certificate into the fs-verity keyring.  This step MUST be
// done on the host kernel.
keyctl padd asymmetric '' %keyring:.fs-verity < cert.der

// Now set up fs-verity on the test file:
fsverity sign file file.sig --key=key.pem --cert=cert.pem \
    --salt 12345678
fsverity enable file --signature=file.sig --salt 12345678

f4d6014c41 data_model: Don't heap allocate in DataInit::from_reader
We can use MaybeUninit instead of heap allocation to ensure that our
buffer has the proper size and alignment. `from_reader` is used for
every message in the fs device and this saves us some unnecessary small
heap allocations.

Switch Reader::read_obj to use this method so that we don't have
multiple implementations of the same thing. This also fixes some
unsoundness in read_obj where we were creating a `&mut [u8]` out of
uninitialized data.

024784d5c0 devices: Merge vhost_user_devices library to devices crate
We originally created `vhost_user_devices` crate so that we'll be able
to have device executables there.
However, we decided to have vhost-user device as crosvm's subcommand.
So, we have no longer a reason to have vhost-user devices as the
separate crate. As the first step to remove the vhost_user_devices
crate, this CL move its main logic to the devices crate.

Note that we add `vhost_user_devices/src/*_device.rs` in this CL as we
need to keep the device executables for a while.

dea7dbb082 Linux: Make vfio kvm file as global
One vm may have one vfio kvm file only, it could be created at vm
setup or runtime through vfio-pci hotplug, make it as global to
satisfy these two cases.

When vfio pci device is removed throgh hotplug out, the vfio group
will be removed frome vfio kvm file also, so move it into vfio.rs,
so it is could be referenced at vfio group's destroy. And
vfio group's destroy is called from vcpu thread, while vfio kvm file
is created in main thread, so use OnceCall instead of thread_local.

VFIO_REGION_INFO_CAP_MSIX_MAPPABLE:

  The MSIX mappable capability informs that MSIX data of a BAR can be
  mmapped which allows direct access to non-MSIX registers which
  happened to be within the same system page.

Add support for this capability so that VfioRegion stores the correct
mmaps information.

Also, fix a couple break conditions to avoid breaking out early.
