They are very conven
rust: support running Rust documentation tests as KUnit ones
Rust has documentation tests: these are typically examples of usage of any item (e.g. function, struct, module...).
They are very convenient because they are just written alongside the documentation. For instance:
/// Sums two numbers. /// /// ``` /// assert_eq!(mymod::f(10, 20), 30); /// ``` pub fn f(a: i32, b: i32) -> i32 { a + b }
In userspace, the tests are collected and run via `rustdoc`. Using the tool as-is would be useful already, since it allows to compile-test most tests (thus enforcing they are kept in sync with the code they document) and run those that do not depend on in-kernel APIs.
However, by transforming the tests into a KUnit test suite, they can also be run inside the kernel. Moreover, the tests get to be compiled as other Rust kernel objects instead of targeting userspace.
On top of that, the integration with KUnit means the Rust support gets to reuse the existing testing facilities. For instance, the kernel log would look like:
KTAP version 1 1..1 KTAP version 1 # Subtest: rust_doctests_kernel 1..59 # rust_doctest_kernel_build_assert_rs_0.location: rust/kernel/build_assert.rs:13 ok 1 rust_doctest_kernel_build_assert_rs_0 # rust_doctest_kernel_build_assert_rs_1.location: rust/kernel/build_assert.rs:56 ok 2 rust_doctest_kernel_build_assert_rs_1 # rust_doctest_kernel_init_rs_0.location: rust/kernel/init.rs:122 ok 3 rust_doctest_kernel_init_rs_0 ... # rust_doctest_kernel_types_rs_2.location: rust/kernel/types.rs:150 ok 59 rust_doctest_kernel_types_rs_2 # rust_doctests_kernel: pass:59 fail:0 skip:0 total:59 # Totals: pass:59 fail:0 skip:0 total:59 ok 1 rust_doctests_kernel
Therefore, add support for running Rust documentation tests in KUnit. Some other notes about the current implementation and support follow.
The transformation is performed by a couple scripts written as Rust hostprogs.
Tests using the `?` operator are also supported as usual, e.g.:
/// ``` /// # use kernel::{spawn_work_item, workqueue}; /// spawn_work_item!(workqueue::system(), || pr_info!("x"))?; /// # Ok::<(), Error>(()) /// ```
The tests are also compiled with Clippy under `CLIPPY=1`, just like normal code, thus also benefitting from extra linting.
The names of the tests are currently automatically generated. This allows to reduce the burden for documentation writers, while keeping them fairly stable for bisection. This is an improvement over the `rustdoc`-generated names, which include the line number; but ideally we would like to get `rustdoc` to provide the Rust item path and a number (for multiple examples in a single documented Rust item).
In order for developers to easily see from which original line a failed doctests came from, a KTAP diagnostic line is printed to the log, containing the location (file and line) of the original test (i.e. instead of the location in the generated Rust file):
# rust_doctest_kernel_types_rs_2.location: rust/kernel/types.rs:150
This line follows the syntax for declaring test metadata in the proposed KTAP v2 spec [1], which may be used for the proposed KUnit test attributes API [2]. Thus hopefully this will make migration easier later on (suggested by David [3]).
The original line in that test attribute is figured out by providing an anchor (suggested by Boqun [4]). The original file is found by walking the filesystem, checking directory prefixes to reduce the amount of combinations to check, and it is only done once per file. Ambiguities are detected and reported.
A notable difference from KUnit C tests is that the Rust tests appear to assert using the usual `assert!` and `assert_eq!` macros from the Rust standard library (`core`). We provide a custom version that forwards the call to KUnit instead. Importantly, these macros do not require passing context, unlike the KUnit C ones (i.e. `struct kunit *`). This makes them easier to use, and readers of the documentation do not need to care about which testing framework is used. In addition, it may allow us to test third-party code more easily in the future.
However, a current limitation is that KUnit does not support assertions in other tasks. Thus we presently simply print an error to the kernel log if an assertion actually failed. This should be revisited to properly fail the test, perhaps saving the context somewhere else, or letting KUnit handle it.

Merge tag 'rust-6.4' of https://github.com/Rust-for-Linux/linux
Pull rust updates from Miguel Ojeda "More additions to the Rust core. Importantly, this adds the pin-init API, which will be used by other abstractions, such as the synchronization ones added here too:
- pin-init API: a solution for the safe pinned initialization problem.
This allows to reduce the need for 'unsafe' code in the kernel when dealing with data structures that require a stable address. Commit 90e53c5e70a6 ("rust: add pin-init API core") contains a nice introduction -- here is an example of how it looks like:
#[pin_data] struct Example { #[pin] value: Mutex<u32>,
#[pin] value_changed: CondVar, }
impl Example { fn new() -> impl PinInit<Self> { pin_init!(Self { value <- new_mutex!(0), value_changed <- new_condvar!(), }) } }
// In a `Box`. let b = Box::pin_init(Example::new())?;
// In the stack. stack_pin_init!(let s = Example::new());
- 'sync' module:
New types 'LockClassKey' ('struct lock_class_key'), 'Lock', 'Guard', 'Mutex' ('struct mutex'), 'SpinLock' ('spinlock_t'), 'LockedBy' and 'CondVar' (uses 'wait_queue_head_t'), plus macros such as 'static_lock_class!' and 'new_spinlock!'.
In particular, 'Lock' and 'Guard' are generic implementations that contain code that is common to all locks. Then, different backends (the new 'Backend' trait) are implemented and used to define types like 'Mutex':
type Mutex<T> = Lock<T, MutexBackend>;
In addition, new methods 'assume_init()', 'init_with()' and 'pin_init_with()' for 'UniqueArc<MaybeUninit<T>>' and 'downcast()' for 'Arc<dyn Any + Send + Sync>'; as well as 'Debug' and 'Display' implementations for 'Arc' and 'UniqueArc'. Reduced stack usage of 'UniqueArc::try_new_uninit()', too.
- 'types' module:
New trait 'AlwaysRefCounted' and new type 'ARef' (an owned reference to an always-reference-counted object, meant to be used in wrappers for C types that have their own ref counting functions).
Moreover, new associated functions 'raw_get()' and 'ffi_init()' for 'Opaque'.
- New 'task' module with a new type 'Task' ('struct task_struct'), and a new macro 'current!' to safely get a reference to the current one.
- New 'ioctl' module with new '_IOC*' const functions (equivalent to the C macros).
- New 'uapi' crate, intended to be accessible by drivers directly.
- 'macros' crate: new 'quote!' macro (similar to the one provided in userspace by the 'quote' crate); and the 'module!' macro now allows specifying multiple module aliases.
- 'error' module:
New associated functions for the 'Error' type, such as 'from_errno()' and new functions such as 'to_result()'.
- 'alloc' crate:
More fallible 'Vec' methods: 'try_resize` and 'try_extend_from_slice' and the infrastructure (imported from the Rust standard library) they need"

rust: uapi: Add UAPI crate
This crate mirrors the `bindings` crate, but will contain only UAPI bindings. Unlike the bindings crate, drivers may directly use this crate if they have to interface with userspace.
Initially, just bind the generic ioctl stuff.
In the future, we would also like to add additional checks to ensure that all types exposed by this crate satisfy UAPI-safety guarantees (that is, they are safely castable to/from a "bag of bits").
[ Miguel: added support for the `rustdoc` and `rusttest` targets, since otherwise they fail, and we want to keep them working. ]
