Subject: [GIT PULL] Rust for v7.4
Date: Sun, 18 Oct 2026 18:34:58 +0200 [thread overview]
Message-ID: <20261018163459.80579-1-ojeda@kernel.org> (raw)
Hi Linus,
This is the next round of the Rust support. This one carries a big diff
due to the `zerocopy` vendored library update, but that is just a mostly
mechanical import in a single commit.
All commits have been in linux-next for 2 rounds or more.
I also did a test merge with your status from a couple hours ago, and it
looks good, without conflicts at the moment.
I am expecting a few easy conflicts with other trees: char-misc, DRM and
Kbuild -- the resolutions in linux-next are fine except that:
- The Kbuild one should remove `RUSTC_HAS_SPAN_FILE` from its new
location in `scripts/Kconfig.toolchain`.
- The DRM one in `rust/kernel/mem.rs` should clean `rustfmt` with:
use crate::prelude::*;
// TODO: `Alignment` should be moved here as well, Rust moved it upstream in 1.96.
pub use crate::ptr::Alignment;
Please pull for v7.4 -- thanks!
Cheers,
Miguel

rust: zerocopy: update to v0.8.62 (2026-10-15 09:14:38 +0200)
----------------------------------------------------------------
Rust changes for v7.4
Toolchain and infrastructure:
- Update vendored 'zerocopy' crate to v0.8.62 (released 2026-10-08).
This update advances 8 releases, with 3 of them carrying most of the
changes. It contains new features as well as fixes. However, almost
nothing has changed that requires updates on our side (a move of our
non-ASCII change and the addition of an SPDX license identifier).
- Generate Rust KUnit test suites for doctests reusing the
'#[kunit_tests]' and '#[test]' attributes instead of C FFI
functions, which allows to remove the generated C glue file.
Relatedly, simplify 'kunit_assert!' by using 'file!()' and 'line!()'
inside (which doctests override as needed), which allows to remove
the 'file' helper and 'CONFIG_RUSTC_HAS_SPAN_FILE'.
- Trim the function names in doctests generated by 'rustdoc' < 1.95.0
when building with 'O=', which were not reproducible.
- Fix the 'VM_MAYSHARE' value in the generated bindings and its
blocklist entry, due to typos.
- Build 'core' with '--cfg no_io_statics' to ensure 'core' does not
introduce any use of 'core::sync::atomic' into the kernel image
since upstream Rust is moving 'std::io::Error' into 'core', which
uses a global atomic pointer.
Upstream Rust merged a PR to add a test checking that builds of
'core' are warning-free with that 'cfg' enabled.
- Enable the unstable 'proc_macro_span' feature in 'proc-macro2',
which provides 'Span::join' and thus improves the quality of the
diagnostics of all our procedural macros, notably 'pin-init'. This
is only used for producing diagnostics, thus there is no hard
reliance on the feature.
- Globally allow 'clippy::comparison_chain', since its suggestions are
not always ideal and upstream downgraded it to 'pedantic' too.
'kernel' crate:
- New 'mem' module: add the 'Align<N>' zero-sized type so that
alignment can be specified via const generics ('repr(align(...))'
only works with integer literals), e.g.:
const N: usize = 128;
struct S {
_align: Align<N>,
}
assert_eq!(align_of::<S>(), N);
- New 'ratelimit' module: add the 'Ratelimit' abstraction for 'struct
ratelimit_state' and, based on it, the 'pr_*_ratelimited!' printing
macros, which can be used for printing that may be triggered by
userspace.
In addition, convert Rust Binder to use them.
- 'sync' module: to construct a global 'struct ratelimit_state', add a
'const' constructor for 'raw_spinlock_t'.
In addition, move the lockdep types into a new 'sync::lockdep'
submodule, since there were starting to be too many of them.
- 'num' module: add the 'cv!' macro to create constant values ("cv")
from an integer constant expression, with validity checked at
compile time, inferring the target type from the context. It works
for any type that implements the new 'FromConst' trait, e.g.:
let a: Alignment = cv!(4096);
let b: Bounded<u32, 4> = cv!(15);
// Any integer constant expression works, not only literals.
let m: NonZero<usize> = cv!(usize::MAX);
// Checked narrowing, including in `const` items.
const SMALL: u8 = cv!(200u32);
// The target type can be given explicitly.
let e = cv!(200u32 => u8);
// With an explicit primitive target, the expression can use
// generic parameters.
const fn as_u64<const KEY: u16>() -> u64 {
cv!(KEY => u64)
}
This avoids the verbose turbofish syntax which disincentivized using
these types at interface boundaries (e.g. 'Alignment::new::<8>()').
- 'alloc' module:
- Allow different error types in 'KBox::pin_slice()', enabling use
of infallible initializers.
- Add 'NumaNode::id()' accessor to retrieve the underlying NUMA
node identifier.
- 'time' module:
- Add 'Delta::to_jiffies_timeout()' for use in timeout arguments.
- Add 'Delta::as_jiffies_unsigned()'.
- Make 'Delta::ZERO' generic over the time unit.
- Warn and assert when passing out-of-range inputs to 'fsleep' and
'udelay'.
- Rename 'ClockSource' to 'ClockId' to better align with naming
conventions in C kernel.
- Make 'CONFIG_HZ' value available as 'bindings::HZ'.
- Add implementation detail documentation for 'HrTimer'.
- 'bitmap' module:
- Add contiguous area operations ('next_zero_area{,_off}', 'set'
and 'clear'), with extra checks compared to the underlying C
code, plus additional ones under 'CONFIG_RUST_BITMAP_HARDENED'.
It includes tests demonstrating the edge cases.
- Restrict bitmap length to at most 'i32::MAX', matching
'BitmapVec::MAX_LEN' and simplifying a few things. This also
fixes 'u32' casts truncating in 'copy_and_extend', which could
otherwise lead to OOB writes.
- 'bug' module:
- Fix 'warn_on!' on UML which called 'warn_slowpath_fmt()' with
the wrong arguments; and fix its '// SAFETY:' comment too.
- Add a KUnit test for 'warn_on!'.
- 'id_pool' module: add contiguous ID reservation via the new
'reserve_ids' and 'release_ids' methods, built on top of the new
bitmap area operations.
- 'sizes' module: add the sub-1K size constants ('SZ_1' to 'SZ_512')
and implement 'SizeConstants' for 'Alignment', so that one can write
e.g. 'Alignment::SZ_8'.
'macros' crate:
- Add '#[optional]' attribute for optional methods in '#[vtable]' to
replace the 'build_error!(VTABLE_DEFAULT_ERROR)' boilerplate, e.g.:
#[vtable]
pub trait Operations: Sized {
#[optional]
fn f(&self) -> Result;
}
In addition, apply it to miscdevice and hide generated 'HAS_'
constants for required methods.
- Allow non-ASCII characters in the 'authors' field of the 'module!'
macro, which was unintentionally restricted when multiple authors
support was introduced.
'pin-init' crate:
[ Extra context from Gary's pull request:
"This is a cycle packed with feature updates. Two of the most
anticipated features, tuple struct support and safe self
reference creation, has been included in this pull request.
Safe self reference is a big one and is pushed a bit late in the
cycle. The initial plan was to include a minimum subset for this
cycle because I was worried about potential soundness issues;
however during Plumbers it was agreed that the features should be
upstreamed at once. This is because the initial users (Nova,
JobQueue) would all need the advanced features, so it is better
to ensure that the feature get put into use for real, and it can
iterate with users, rather than being fully designed on paper.
The existing safety checks are already very comprehensive, and
Benno and I are confident that if new ones are discovered, it
wouldn't affect the overall design.
That said, the the usage of the advanced features (invariance,
existential lifetime) shall be limited to the pre-agreed users
only, so even in case where the feature needs to be reworked, the
blast radius is limited.
Another theme in this cycle is to improve the developer
experience when things are used wrongly. A lot of work has been
done to use proper spans from user-provided tokens so error
message point to things that cause them. Many common misuse
scenarios also gain additional custom diagnostics." ]
- User visible changes:
- Support tuple structs.
- Allow safe creation of self references.
- Vastly improve diagnostics for common misuse scenarios.
- Other changes:
- Use 'mixed_site' hygiene consistently.
'MAINTAINERS':
- Add 'RUST [BUG]' entry for the Rust 'bug' module (i.e. 'warn_on!'),
which will be maintained by FUJITA Tomonori -- thank you!
- Add Alice Ryhl as co-maintainer for 'Rust [ALLOC]'.
And some other fixes, cleanups and improvements.
