Merge tag 'spdx-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdxPull SPDX updates from Greg KH: "Here is a "big" set of SPDX-like patches for 7.2-rc1. It is the addition of the ability for the kernel build process to generate a Software Bill of Materials (SBOM) in the SPDX format, that matches up exactly with just the files that are actually built for the specific kernel image generated. To generate a sbom, after the kernel has been built, just do: make sbom and marvel at the JSON file that is generated... This is needed by users for environments in which a SBOM is required (medical, automotive, anything shipped in the EU, etc.) and cuts down by a massive size the "naive" SBOM solution that many vendors have done by just including _all_ of the kernel files in the resulting document. This result is still a giant JSON file, that I am told parses properly, so we just have to trust that it is properly inclusive as attempting to parse that thing by hand is impossible. The scripts here are self-contained python scripts, no additional libraries or tools to create the SBOM are needed, which is important for many build systems. Overall it's just a bit over 4000 lines of "simple" python code, the most complex part is the regex matching lines, but those are nothing compared to what we maintain in scripts/checkpatch.pl today... The various parts where the tool touches the kbuild subsystem have been acked by the kbuild maintainer, so all should be good here.

Tue, 16 Jun 2026 14:30:38 +0200

rust: Kbuild: set frame-pointer llvm module flag for CONFIG_FRAME_POINTERDue to a rustc bug, the -Cforce-frame-pointers=y flag only emits theframe-pointer annotation for functions, but not for the module. Thismeans that functions generated by the LLVM backend such as'asan.module_ctor' do not receive the frame-pointer annotation.This is likely to lead to broken backtraces and may also cause issueswith ftrace if these features are used with functions generated by theLLVM backend.Thus, use -Zllvm_module_flag to work around this rustc bug if using arustc without the fix.[ The fix [1] has landed for Rust 1.98.0 (expected release on 2026-08-20). - Miguel ]Cc: stable@vger.kernel.org # 6.12.y and later (flag not available in pinned Rust in older LTSs).Fixes: 2f7ab1267dc9 ("Kbuild: add Rust support")Link: https://github.com/rust-lang/rust/pull/156980 [1]Signed-off-by: Alice Ryhl Link: https://patch.msgid.link/20260616-frame-ptr-fix-v1-1-dc6b29a631d9@google.com[ - Adjusted Cc: stable@ as discussed. - Added comment with link to the PR, similar to what we did in commit ac35b5580ace ("rust: arm64: set uwtable llvm module flag for CONFIG_UNWIND_TABLES"). - Miguel ]Signed-off-by: Miguel Ojeda List of files: /linux/Makefile

Mon, 15 Jun 2026 05:55:48 +0200

Merge tag 'rust-7.2' of gitolite.kernel.org:pub/scm/linux/kernel/git/ojeda/linuxPull Rust updates from Miguel Ojeda: "This one is big due to the vendoring of the `zerocopy` library, which allows us to replace a bunch of `unsafe` code dealing with conversions between byte sequences and other types with safe alternatives. More details on that below (and in its merge commit). Toolchain and infrastructure: - Introduce support for the 'zerocopy' library [1][2]: Fast, safe, compile error. Pick two. Zerocopy makes zero-cost memory manipulation effortless. We write `unsafe` so you don't have to. It essentially provides derivable traits (e.g. 'FromBytes') and macros (e.g. 'transmute!') for safely converting between byte sequences and other types. Having such support allows us to remove some 'unsafe' code. It is among the most downloaded Rust crates and it is also used by the Rust compiler itself. It is licensed under "BSD-2-Clause OR Apache-2.0 OR MIT". The crates are imported essentially as-is (only +2/-3 lines needed to be adapted), plus SPDX identifiers. Upstream has since added the SPDX identifiers as well as one of the tweaks at my request, thus reducing our future diffs on updates -- I keep the details in one of our usual live lists [3]. In total, it is about ~39k lines added, ~32k without counting 'benches/' which are just for documentation purposes. The series includes a few Kbuild and rust-analyzer improvements and an example patch using it in Nova, removing one 'unsafe impl'. I checked that the codegen of an isolated example function (similar to the Nova patch on top) is essentially identical. It also turns out that (for that particular case) the 'zerocopy' version, even with 'debug-assertions' enabled, has no remaining panics, unlike a few in the current code (since the compiler can prove the remaining 'ub_checks' statically). So their "fast, safe" does indeed check out -- at least in that case. - Support AutoFDO. This allows Rust code to be profiled and optimized based on the profile. Tested with Rust Binder: ~13% slower without AutoFDO in the binderAddInts benchmark (using an app-launch benchmark for the profile). - Support Software Tag-Based KASAN. In addition, fix KASAN Kconfig by requiring Clang. - Add Kconfig options for each existing Rust KUnit test suite, such as 'CONFIG_RUST_BITMAP_KUNIT_TEST'. They are placed within a new menu, 'CONFIG_RUST_KUNIT_TESTS', in the new 'rust/kernel/Kconfig.test' file. - Support the upcoming Rust 1.98.0 release (expected 2026-08-20): lint cleanups and an unstable flag rename. - Disable 'rustdoc' documentation inlining for all prelude items, which bloats the generated documentation. - Ignore (in Git) and clean (in Kbuild) the (rarely) 'rustc'-generated '*.long-type-*.txt' files. 'kernel' crate: - Add new 'bitfield' module with the 'bitfield!' macro (extracted from the existing 'register!' one), which declares integer types that are split into distinct bit fields of arbitrary length. Each field is a 'Bounded' of the appropriate bit width (ensuring values are properly validated and avoiding implicit data loss) and gets several generated getters and setters (infallible, 'const' and fallible) as well as associated constants ('_MASK', '_SHIFT' and '_RANGE'). It also supports fields that can be converted from/to custom types, either fallibly ('?=>') or infallibly ('=>'). For instance: bitfield! { struct Rgb(u16) { 15:11 blue; 10:5 green; 4:0 red; } } // Compile-time checks. let color = Rgb::zeroed().with_const_green::<0x1f>(); assert_eq!(color.green(), 0x1f); assert_eq!(color.into_raw(), 0x1f << Rgb::GREEN_SHIFT); Add as well documentation and a test suite for it, as usual; and update the 'register!' macro to use it. It will be maintained by Alexandre Courbot (with Yury Norov as reviewer) under a new 'MAINTAINERS' entry: 'RUST [BITFIELD]'. - 'ptr' module: rework index projection syntax into keyworded syntax and introduce panicking variant. The keyword syntax ('build:', 'try:', 'panic:') is more explicit and paves the way of perhaps adding more flavors in the future, e.g. an 'unsafe' index projection. For instance, projections now look like this: fn f(p: *const [u8; 32]) -> Result { // Ok, within bounds, checked at build time. project!(p, [build: 1]); // Build error. project!(p, [build: 128]); // `OutOfBound` runtime error (convertible to `ERANGE`). project!(p, [try: 128]); // Runtime panic. project!(p, [panic: 128]); Ok(()) } Update as well the users, which now look like e.g. // Pointer to the first entry of the GSP message queue. let data = project!(self.0.as_ptr(), .gspq.msgq.data[build: 0]); - 'build_assert' module: make the module the home of its macros instead of rendering them twice. - 'sync' module: add 'UniqueArc::as_ptr()' associated function. - 'alloc' module: - Fix the 'Vec::reserve()' doctest to properly account for the existing vector length in the capacity assertion. - Fix an incorrect operator in the 'Vec::extend_with()' 'SAFETY' comment; add a doc test demonstrating basic usage and the zero-length case. - Clean imports across several modules to follow the "kernel vertical" import style in order to minimize conflicts. 'pin-init' crate: - User visible changes: - Do not generate 'non_snake_case' warnings for identifiers that are syntactically just users of a field name. This would allow all '#[allow(non_snake_case)]' in nova-core to be removed, which Gary will send to the nova tree next cycle. - Filter non-cfg attributes out properly in derived structs. This improves pin-init compatibility with other derive macros. - Insert projection types' where clause properly. - Other changes: - Bump MSRV to 1.82, plus associated cleanups. - Overhaul how init slots are projected. The new approach is easier to justify with safety comments. - Mark more functions as inline, which should help mitigate the super-long symbol name issue due to lack of inlining. rust-analyzer: - Support '--envs' for passing env vars for crates like 'zerocopy'. 'MAINTAINERS': - Add the following reviewers to the 'RUST' entry: - Daniel Almeida - Tamir Duberstein - Alexandre Courbot - Onur Özkan They have been involved in the Rust for Linux project for about 7 collective years and bring expertise across several domains, which will be very useful to have around in the future.

Wed, 10 Jun 2026 21:55:25 +0200

kbuild: Use ld.lld for linking host programs when LLVM is setCurrently, host programs are linked with HOSTCC using the toolchain'sdefault linker. This can result in confusing behavior when using theLLVM Kbuild variable (which states that the user would like to buildwith the LLVM toolchain instead of the GNU one), as clang's defaultlinker is ld for most platforms, not ld.lld. The documentation mentionsHOSTLD=ld.lld is set but this variable is not used by Kbuild proper,only within some tools/ projects. Kbuild provides the HOSTLDFLAGSvariable, which allow users to provide the '-fuse-ld' or '--ld-path'flags to customize what linker is used, but this is not super obvious tofolks not familiar with Kbuild.If the user has not customized the linker already using one of theseflags, default to ld.lld when using the LLVM variable, which is more inline with user expectations when using that variable.Closes: https://github.com/ClangBuiltLinux/linux/issues/2167Link: https://patch.msgid.link/20260610-kbuild-use-lld-for-linking-hostprogs-v1-1-70396fe42ee3@kernel.orgSigned-off-by: Nathan Chancellor List of files: /linux/Makefile

Wed, 27 May 2026 16:27:03 +0200

kconfig: add kconfig-sym-check static checkerAdd 'make kconfig-sym-check', a static checker that finds Kconfigsymbols referenced in expressions (select, depends on, default, etc.)but never defined via config/menuconfig anywhere in the tree. Newdangling symbols are reported as errors (exit 1) unless they arelisted in an exclusion file, e.g. KCONFIG_SYM_CHECK_EXCLUDES=sym-check-excludes make kconfig-sym-checkThe exclusion file lists one symbol per line; blank lines and linesstarting with '#' are ignored.The checker also warns about uppercase N/Y/M used as tristate literalvalues following the same logic as checkpatch.This new static checker is the script used for [1] with a fewimprovements to avoid some false positives.Link: https://bugzilla.kernel.org/show_bug.cgi?id=216748 [1]Assisted-by: Claude:claude-sonnet-4-6Signed-off-by: Andrew Jones Acked-by: Andy Shevchenko Acked-by: Randy Dunlap Tested-by: Randy Dunlap Tested-by: Julian Braha Tested-by: Nicolas Schier Acked-by: Nicolas Schier Link: https://patch.msgid.link/20260527142703.107110-1-andrew.jones@linux.devSigned-off-by: Nathan Chancellor List of files: /linux/Makefile

Sat, 30 May 2026 20:49:43 +0200

kbuild: rust: clean `*.long-type-*.txt` filesWhen rustc prints an error containing a long type that doesn't fitin a line, it will write the whole thing in a .txt file -- see commit420dd187e157 (".gitignore: ignore rustc long type txt files") for moredetails.These files are purely compiler artifacts and are not createdintentionally by the build system.Thus add them to the `clean` target to stop them from cluttering up thesource tree.Suggested-by: Miguel Ojeda Link: https://github.com/Rust-for-Linux/linux/issues/1236Signed-off-by: Joel Kamminga Acked-by: Nathan Chancellor Link: https://patch.msgid.link/20260530184944.10459-1-contact@jkam.dev[ Reworded and linked to the previous related commit. - Miguel ]Signed-off-by: Miguel Ojeda List of files: /linux/Makefile
