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 The following changes since commit 72d3fcf802c45d00b300f25b848a93c3a2bd7c7e: Linux 7.3-rc5 (2026-09-27 13:55:01 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux.git tags/rust-7.4 for you to fetch changes up to 7c306f00835a237a70024a8f968dbc3bc8db8fcf: 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' 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, } assert_eq!(align_of::(), 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 = cv!(15); // Any integer constant expression works, not only literals. let m: NonZero = 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() -> 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]'.
