daceeb59c6 sys_util: add tool for raw descriptor reflection
This CL enables serde based serialize and deserialize types to interact
with a side-channel stash of descriptors. The idea is that many types
could implement Serialize and Deserialize, but they have descriptors
buried in them, such as a File or kernel object. Although these can be
serialized literally, usually the transciever of the serialized value
needs explicit access to the descriptors to send them over, such as with
Unix domain sockets.

This removes some unsafe code, improving the interface so that it cannot
be misused (e.g. previously, different Vec<u8> instances could be passed
to fdt functions that did not validate the contents).

The new implementation also adds some extra error checking to catch
invalid string values in all API entry points that accept strings, as
well as out-of-order node nesting that would result in DTB data that did
not conform to the spec.

503c5abef6 devices: Add an asynchronous block device
This enables the use of basic disk images with async IO. A new
block_async.rs is added which mostly mirrors block, except that all
IO operations are asynchronous allowing for multiple virt queues to be
used.

The old block remains unchanged and is still used for qcow, android
sparse, and composite disks. Those should be converted to as time
allows, but this dual approach will have to do for now so ARCVM disk
performance can be properly evaluated.

This is the original CL with one minor exception: we don't bind
mount the camera socket with the GPU device.  That was the prior
behavior, and for some reason it really doesn't work with Mali +
SECCOMP[1].  It's not really important for the Wayland prototype,
so we'll let the camera team figure it out if and when they are
so inclined.

The cross-domain context is specialized for cross domain

The goal here is just to introduce the building blocks so we

* Recieves responses via a shared ring buffer of type BLOB_MEM_GUEST.
  The synchronization protocol looks positively primitive compared to
  the revolutionary Address Space Graphics (ASG) algorithm [1], but
  it may be sufficient for the Wayland use case.

293913c01a rutabaga_gfx: rutabaga_gralloc: a shimmering beacon of hope
rutabaga_gralloc is a cross-platform, Rust-based buffer
manager.

The rationale for this change is:

1) For the {cross-domain, wayland} context type, we need to
have a good story for the crucial "wl-dmabuf" feature.  As
minigbm has been thoroughly tested on ChromeOS and currently
powers the "wl-dmabuf" feature, it only makes sense for us to
have a path to minigbm for the cross-domain prototype.  This
will be used by Sommelier.

2) While minigbm allocation works well on Chromebooks, it is
not sufficient for cross-platform purposes.  For their Virtual
Graphics Interface (VGI) initiative, Android graphics
virtualization experts have expressed their desire for a Vulkan
based allocator.  This will to go alongside cros_gralloc in
minigbm, which is considered by many to be the ""world's
premiere gralloc implementation".

3) Android graphics virtualization experts have expressed their
desire for vkMapMemory(..) to be used when crosvm is in
multi-process mode.  Currently, only dma-buf mmap() is supported
for zero-copy blobs in multi-process mode.  dma-buf mmap() is not
guaranteed to work on Nvidia (a "must have" for Cuttlefish) or
any other driver for that matter (we *make* it work for ChromeOS).
Possibly only solution: vkMapMemory ;-)

With these goals in mind, here's a summary of the revelant changes:

* Renamed the {gpu_allocator.rs, GpuMemoryAllocator trait} to be
  {gralloc.rs, Gralloc trait}.

* Moved all GPU allocation out of the resources crate and into
  the rutabaga_gfx crate.  This will allow the resources crate to
  be focused on managing resources for virtual machines.

* Moved the gpu_buffer crate into the gralloc module in the
  rutabaga_gfx crate.  The same functionality is now under
  "minigbm.rs", "minigbm_bindings.rs" and "rendernode.rs"

* Added an optional dependency on vulkano.rs.  vulkano.rs is a safe
  Rust wrapper around the Vulkan api [a].  It's emphasis on type
  safety makes a good fit for crosvm, though there are other high
  quality crates out there (gfx-rs, ash.rs).  Though development
  has slowed down, it should satisfy goals (2) and (3) quite easily.

* Added a system_gralloc implementation based on memfd.  This can be
  used when minigbm or Vulkano features are not used, to replicate the
  highly useful "wl-shm" feature in Sommelier.  Astute observers will
  note this can also enable seamless Wayland windowing without GPU
  features for Android too.  Some minor changes to the base crate were
  needed.

* Cut down on the amount of DrmFormats to the subset needed by
  Sommelier and cros_gralloc.

* Moved checked arithmetic into it's own file.

* Internally renamed to "wl-dmabuf" feature to be the "minigbm"
  feature.  This is because "wl-dmabuf" has a dependency on minigbm.

* Small rutabaga_gfx cleanups

1fcc8a8f3c io_uring: Make UringContext Sync
Rather than requiring callers to wrap the entire UringContext in a big
lock, make UringContext Sync by internally using fine-grained locks:

* The submit queue is wrapped with a Mutex so that threads may still add
  operations to the submit queue even when a thread is blocked
  inside an io_uring_enter call.
* The completion queue internally uses a Mutex around the pending op
  data and completed count so that two threads don't end up trying to
  remove the same operation from the completed queue.

With this we can enable the await_uring_from_poll test.  This test
uncovered missing wakeups in the case where a uring operation is added
from one thread while the main uring thread is blocked inside an
io_uring_enter syscall. To deal with this, we call submit() whenever the
pending operation is polled and not yet submitted.

f1ce859903 cros_async: Refactor executors
There are a lot of changes in this one but these are the high-level
points:

* Both executors now support non-fd futures and it's now possible to
  start a poll operation on one thread and then await the result inside
  a UringExecutor on another thread.  The reverse doesn't work yet but
  will once we make UringContext sync.
* A few layers of indirection have been removed so hopefully both the
  implementation and the interface are simpler.
* The thread local magic is gone in favor of directly calling methods on
  an executor.  Executor handles can be cheaply cloned to make this
  easier.
* Heap allocations are limited to the spawn and spawn_local methods so
  it's possible to completely avoid heap allocations if callers only use
  the run_until method.
* The IoSource, Executor, FutureList traits are gone.

- Some repos have transitioned to a main branch. Fixed our uprev

0797a55462 Framework for extended integration tests
This CL expands the existing boot.rs test to not just boot a kernel
but also provide a debian-based rootfs and a special init binary
that is used to communicate between test code and the guest VM.

The delegate binary listens for commands on /dev/ttyS1 and returns
the stdout of the executed command.
This allows the test code to setup pipes for the serial device to
issue commands in the client and receive the command output, which
provides a good foundation for tests of basic functionality without
the need to pass test binary code into the guest.

The integration tests will pull a prebuilt kernel and rootfs image
from cloud storage unless local files are specified via ENV variables.

The integration_tests/guest_under_test directory contains the files
needed to build and upload those prebuilts.

This CL adds the foundation for running tests consistently
in Kokoro and locally, for both x86 and aarch64.

The crosvm_builder is similar to the original image from
docker/crosvm.Dockerfile.
The main difference is that ChromeOS dependencies are not
compiled into the container, but built at runtime.

The crosvm_aarch64_builder installs the build enviornment
to cross-compile crosvm for aarch64. The tests are run
with user-space emulation using qemu-aarch64-static.

See ci/README.md for instructions on how to use these
builders.

Tests on aarch64 cannot all be run using user-space
emulation. We will need a VM to pass all smoke tests,
this work is tracked in b/177228167.

Vulkan-centric Virtual Graphics Interface (VGI).

Apologies for the mega-change, but it was hard to do this piece
by piece.

The rationale for this change is:

1) Android graphics virtualization experts have been proposing
for a VGI for many months (years?).  Their goal is to boot
Android anywhere, everywhere.

2) For the {wayland, cross-domain} context type prototype,
it's desirable to create a {wayland, camera} connection at the
appropriate time. Details can be found in the code, though the
RutabagaChannels have yet to be hooked up.

There's a high chance neither effort will work.  As such,
rutabaga is just a prototype.

However, even (1) and (2) don't end up working, this
refactor/cleanup by itself makes a ton of sense.

Here's a summary of revelant changes:

* Removed auto-generated {p_defines, p_format, virgl_protocol}.
These files were added for tests when bringing up crosvm-gpu,
and AFAICT these tests are not run.  There's actually now a
commit queue for virglrenderer changes and container boot tests
that provides excellent coverage.

* Removed command_buffer.rs.  Used only for the previously
mentioned tests.  It's quite nice, but couldn't determine the right
place to put it.  Maybe data_model?  But removed it in the interim.

* Removed {write_from_guest_memory, read_to_volatile}.  The same
basic functionality has been moved into {transfer_write,
transfer_read} in Rutabaga.

* Removed VirtioResource, Virtio3DResource, Virtio2DResource,
and VirtioGfxStreamResource in favor of VirtioGpuResource and
RutabagaResource.  This leads to less duplication and clearer
separation between external library functions and VMM functions.

* Moved display and hypervisor memory management functions to
virtio_gpu.rs.  This is because external components do not interface
with this functionality, and there was a lot of duplication (for example
map/unmap blob).

* Added context management between gfxstream and virglrenderer.

* Added separate gfxstream and virglrenderer flags.

* Clearer naming.

* Added simple implementations for context init and multiple timelines.
These changes have no effect since all Google kernels don't pass the
revelant flags, but are useful for theoretical {wayland, cross-domain}
prototype.

* Unify RESOURCE_CREATE_3D and RESOURCE_CREATE_2D handling.

* Better error handling.

977c67e2a6 Upgrade Cargo.lock format to v2.
Inside new chroots, the Rust toolchain is new enough to write the v2
version of the lock file format by default when a new dependency is
added. This leads to large unintended diffs if a new package is added
and the newer toolchain is used to build. To avoid these hassles,
this CL updates CrosVM's lock file to use the new format.

b3fca20e24 Refactor cros_async interface to avoid RawFd.
Instead of creating IoSourceExt from AsRawFd implementers, we've
switched to creating from a marker trait `IntoAsync`. This lets us use
other types like RawDescriptor easily with this crate.  By using the
marker, we also provide some type safety by requiring consumers of
IoSourceExt to declare that their type is expected to work with async
operations. This way we can provide stronger guarantees that an async
IO trait object will behave in a reasonable way.

This CL also purges the cros_async -> base and io_uring -> base
references, and provides the base types needed to add new async
primitives to base.
