Rust support

This is the patch series to add support for Rust as a second language
to the Linux kernel.

If you are interested in following this effort, please join us in
the mailing list at:

    rust-for-linux@vger.kernel.org

and take a look at the project itself at:

# Rust support

This cover letter explains the major changes and updates done since
the RFC sent in the previous merge window back in April, plus a few
extra notes and announcements. For the RFC, please see:

    https://lore.kernel.org/lkml/20210414184604.23473-1-ojeda@kernel.org/


## Rust infrastructure updates

There have been several major improvements to the overall Rust
support. The following subsections cover these.


### Removed panicking allocations

We have removed infallible allocations. In order to do so, we have
integrated a subset of the `alloc` standard library crate, with some
additions on top. This allows us to customize things to our needs,
while giving upstream the time they need to evaluate our changes.

Eventually, the goal is to have everything the kernel needs in
upstream `alloc` and drop it from the kernel tree. We have already
started this process and some changes have been already accepted
upstream.

On top of that, `alloc` is now compiled with panicking allocation
methods disabled, thus they cannot be used within the kernel by
mistake either.

Moreover, the documentation for this customized `alloc`  crate (as well
as for `core`) is now generated alongside the rest of the Rust kernel
documentation. Thus kernel developers can now easily browse the subset
that is available within the kernel. Like last time, you can take
a look at a preview of the documentation at:

     https://rust-for-linux.github.io/docs/alloc/

Note that the `compiler_builtins` panicking intrinsics are still
there, but those will be solved by partitioning `core` via feature
gates. The first one, for disabling floating-point functionality,
has just been accepted upstream.


### Beta compiler supported

Up until now, we have been using nightly releases of `rustc` because
we need some of the latest fixes and unstable features.

However, the kernel can now be compiled with beta and stable `rustc`
releases. At the moment, we are using the 1.54-beta1 version as our
reference compiler. At the end of this month, `rustc` 1.54 will be
released, and we will move to that version as our reference.

Note that the kernel still requires unstable features, even if it is
compiled with a stable `rustc` release, thus we cannot guarantee that
future `rustc` versions will work without changes to the kernel tree.

Thus, until all the unstable features we need are stabilized, we will
support a single `rustc` version for each kernel release.


### Testing support

Another big addition has been the support for testing. We now support
the standard Rust `#[test]` attribute to easily write tests, e.g.:

    #[test]
    fn f() {
        let a = 20;
        let b = 22;
        assert_eq!(a + b, 42);
    }

Furthermore, we are now also supporting Rust documentation tests
("doctests"). These allow us to make sure our examples remain up to
date, and also double as tests too, e.g.:

    /// ```
    /// assert_eq!(foo::f(), 42);
    /// ```
    pub fn f() -> i32 {
        42
    }

For the moment, both kinds of tests are run in the host only, but
the goal is to have them running in kernel space, so that we can
test code that depends on kernel features, and to allow any kernel
module to declare and use them.


### Architectures and compiler support

`arm` (i.e. 32-bit) and `riscv` are now also supported.

On compilers, we would like to mention all the work that has been
going in GCC Rust (a GCC frontend for the Rust language) and
`rustc_codegen_gcc` (a `rustc` backend for GCC). The latter now passes
all `core` tests, and the former is now working on traits. We continue
to track their progress as they may become the best way to have
GCC-built kernels with Rust support enabled. Their latest reports
can be found at:

    https://blog.antoyo.xyz/rustc_codegen_gcc-progress-report-1
    https://thephilbert.io/2021/06/28/gcc-rust-weekly-status-report-20/

On top of that, we requested Compiler Explorer to add support to all
the alternative compilers. At the time of writing, they have already
added `mrustc` and GCC Rust; and `rustc_codegen_gcc` is coming soon.
See a live example at:

    https://godbolt.org/z/8o74c57Yj


## Rust abstractions and driver updates

We have developed new Rust abstractions that use the kernel C
implementations: red-black trees, reference-counted objects, file
descriptor creation, tasks, files, io vectors...

Additionally, we have improved driver support: improvements to
`file_operations` (more operations supported, arbitrary state),
reduced boiler-plate code, improved `module!` macro, registration
macros, rudimentary (`probe` and `remove`) platform drivers...

On Binder, there is now support for transferring files descriptors
and LSM hooks; and we are working on preliminary performance numbers.

Moreover, there is ongoing work on a Rust example driver,
`bcm2835-rng`. This is the hardware random-number generator present
on Raspberry Pi Zero(W), Classic, Two, and Three.

There are other small improvements, such as drivers being restricted
on what unstable features they can use.


## Patch series status

Like it was mentioned in the RFC, the Rust support is still to be
considered experimental. However, as noted back in April, support is
good enough that kernel developers can start working on the Rust
abstractions for subsystems and write drivers and other modules.

Please note that the current series have just arrived in `linux-next`,
thus the first run will happen on Tuesday.


## Industry and academia support

We have been in contact with a set of companies and academia members
that would like to use Rust as a second language in the kernel. Some
of them have already started to evaluate Rust for their needs using
the infrastructure we have already in place.

In particular, we have got a few statements from major companies.
In no particular order:

  Microsoft's Linux Systems Group is interested in contributing to
  getting Rust into Linux kernel. Hopefully we will be able to submit
  select Hyper-V drivers written in Rust in the coming months.

  Arm recognises the Rust value proposition and is actively working
  with the Rust community to improve Rust for Arm based systems.
  A good example is Arm’s RFC contribution to the Rust language which
  made Linux on 64-bit Arm systems a Tier-1 Rust supported platform.
  Rustaceans at Arm are excited about the Rust for Linux initiative
  and look forward to assisting in this effort.

  Google supports and contributes directly to the Rust for Linux
  project. Our Android team is evaluating a new Binder implementation
  and considering other drivers where Rust could be adopted.

In addition, IBM contributed the Rust kernel support for PowerPC
which was already included in the RFC.

In addition, from academia, there are already several projects around
Rust for Linux going on. As an example, members of LSE (Systems
Research Laboratory) at EPITA (École pour l'informatique et les
techniques avancées) are developing an SPI Rust driver.

And, of course, special thanks go to ISRG (Internet Security Research
Group) and Google for their financial support on this endeavor.


## Conferences and talks

We have submitted talk proposals for LPC (Linux Plumbers Conference).

The main one will describe the work we have done so far and ideally
will also serve as an introduction for other kernel developers
interested in using Rust in the kernel. It will cover an introduction
of the language within the context of the kernel, how the overall Rust
support works, how code is documented, how tests are written, a tour
of available tooling, an explanation of coding guidelines, how kernel
driver code looks like, etc.

In addition, we would like to announce that we are organizing a new
conference that focuses on Rust and the Linux kernel. The first
edition will be virtual and will take place before LPC. Details will
be announced soon.


## Acknowledgements

The signatures in the main commits correspond to the people that
wrote code that has ended up in them at the present time. For details
on contributions to code and discussions, please see our repository:

However, we would like to give credit to everyone that has contributed
in one way or another to the Rust for Linux project. Since the RFC:

  - bjorn3 for all the input on Rust compiler details and all
    the reviews and suggestions.

  - Arthur Cohen, Esteban Blanc and Martin Schmidt for their ongoing
    work on the SPI abstractions and driver.

    `cfg` feature in upstream `alloc` to easily disable all
    functionality that relies on panicking allocations.

  - Josh Triplett and John Ericson for their input on `alloc` which
    helped us decide what to do with it (i.e. fully custom vs.
    slightly custom in-tree copy vs. upstream), as well as offering
    to help moving forward some needed features on the Rust side.

  - Mark Rousskov for answering some questions about beta backports
    and scheduling, as well as working on unsticking `1.54.0-beta.1`.
