Rust changes for v7.3
Toolchain and infrastructure:
- Warn when using 'bindgen' < 0.72.1 with 'libclang' >= 22, since that
combination may fail to build. It includes a probe for the bug in
case 'bindgen' happens to be patched, and tests.
In parallel, Nathan updated the instructions for the kernel.org
LLVM+Rust toolchains so that the latest version of 'bindgen' is
installed, which should avoid some of these situations.
- Support testing 'rust_is_available.sh' with 'bash' as '/bin/sh'.
- Fix an objtool warning by adding one more 'noreturn' function for
Rust 1.99.0 (expected 2026-10-01).
- Fix build error in the 'rusttest' target due to ambiguity when the
'rustc-dev' component is installed, which was uncovered by the work
to support Rust's GCC backend ('rustc_codegen_gcc').
- Fix future Clang warnings in the upcoming powerpc support due to
macro redefinitions in the UAPI helper header by including the
arch-aware 'ioctl.h' header.
'kernel' crate:
- Rework module ownership support:
- Move the module-related types into a new 'module' module and make
the 'THIS_MODULE' pointer a constant of 'ModuleMetadata' so that
modules can provide the pointer in const contexts, and add a
'this_module' 'const fn' to retrieve it.
This was enabled by upstream Rust's work on the 'const_mut_refs'
and 'const_refs_to_static' features which were stabilized back
in Rust 1.83.0.
- Teach '#[vtable]' to associate implementations with their owning
module, defaulting to the local one, including fallbacks for
doctests, uses within the 'kernel' crate (like upcoming KUnit
'#[test]'s for DRM) and 'rusttest'.
- Set 'fops.owner' from the module pointer for DRM and miscdevice.
- Migrate Rust Binder and configfs away from the old 'THIS_MODULE'
'static' and finally remove it from the 'module!' macro.
- 'num' module:
- Add the new 'casts' module for lossless integer conversions.
Rust's 'core' library's 'From' implementations do not cover
conversions that are not portable or future-proof. However, the
kernel supports a narrower set of architectures, which makes it
helpful to provide more infallible conversions, instead of having
developers use 'as' casts, which carry the risk of silently
losing data.
This goes along with previous work we did to avoid casts in Rust
kernel code since they are more powerful than needed.
Thus, provide safe 'const' conversion functions (e.g.
'usize_as_u64' and 'u64_into_u8'), as well as the 'FromSafeCast'
and 'IntoSafeCast' extension traits that provide conversions that
are known to be lossless in the kernel, and an 'arch' submodule
defining conversions that are known to be lossless on particular
architectures (e.g. 64-bit platforms). For instance:
// Conversion in const context.
const USIZED_CONST: usize = u8_as_usize(255u8);
// Non-const conversions.
let a = u64::from_safe_cast(4096usize);
let b: u64 = 4096usize.into_safe_cast();
- Add 'Bounded::shr_exact' method in the vein of 'try_shrink' which
shifts a bounded right only if it loses no set bits.
- Fix unsoundness issue in the 'Bounded::shr' method by rejecting,
at compile-time, shifts of at least the type's bit width.
- 'fmt' module:
- Route '{:p}' raw pointer formatting through the kernel's hashed
'%p' format to prevent address leaks, including support for width
and padding. Include tests for both 'no_hash_pointers' case and
the default (hashed) one.
- Fix the '{:p}' forwarding implementation, which could print the
address of a temporary stack variable.
- 'time' module:
- Make 'Delta' generic over its time unit, with a default unit of
nanoseconds ('Nsec'), preserving the existing behavior. Then, add
a 'Jiffy' time unit.
- Add the 'Delta::as_millis_ceil()' method.
- Fix 'as_micros_ceil()' rounding near 'i64::MAX', which could
yield a result one microsecond too small.
- 'sync' module:
- Implement 'ForeignOwnable' for 'ARef<T>', allowing C code to own
an 'ARef<T>'.
- Add a safe abstraction for 'rcu_barrier()'.
- 'error' module: add all of the remaining error codes, except the
deprecated compatibility aliases.
- 'bug' module:
- Fix build error on UML in 'warn_on!' for callers from within
the 'kernel' crate.
- Fix future 'dead_code' warning on arm and loongarch64 and under
'CONFIG_BUG=n' in 'warn_on!', which would trigger with the
upcoming SRCU abstractions.
- Fix future build error in 'rusttest' on cross-compilation cases,
which would trigger when 'warn_on!' has callers inside the
'kernel' crate.
- 'bitfield' module: fix build error for the upcoming support for
Rust's GCC backend ('rustc_codegen_gcc') by always inlining a couple
conversions used in tests.
'pin-init' crate:
- User-visible changes:
- Merge the '__pinned_init' and '__init' methods and make 'Init'
a marker trait.
- Introduce public APIs 'raw_init' and 'raw_try_init' to prevent
users from needing to invoke the internal
'__pinned_init'/'__init' methods.
- Emit errors for duplicate '#[pin]' attributes.
- Link 'Zeroable::zeroed' and 'pin_init::zeroed' in documentation.
- Other changes:
- Fix unwind safety issues.
- Clean up lint 'allow' and 'expect's.
- Overhaul '#[cfg]' handling to pave the way for tuple structs and
self-referential structs.
- Mark many functions as '#[inline]' for better codegen with '-C
opt-level=s' ('CC_OPTIMIZE_FOR_SIZE').
'MAINTAINERS':
- Update 'MODULE SUPPORT' to cover the new 'module' module.
And some other fixes, cleanups and improvements.

Kbuild/Kconfig updates for 7.3
Kbuild updates
==============
* Use --force-group-allocation when linking modules
Have the linker resolve the COMDAT groups and place their members as
regular sections instead of possibly leaving multiple copies in the
resulting modules and unnecessary group metadata.
* UAPI header files: Canonicalize __ASSEMBLER__ / __ASSEMBLY__ mixed
use to __ASSEMBLER__
There is an ongoing effort to change __ASSEMBLY__ to __ASSEMBLER__
treewide. For consistency, UAPI headers are normalised to use
__ASSEMBLER__ only. Normalisation is done in two subsequent patches
to simplify a revert in the unexpected case of a regression report.
* link-vmlinux.sh: Improve detection of third pass requirement
* modpost: Canonicalize format of warnings and errors
* Minor changes:
- Remove srctree path from CHECK output
- Set the initial value of subdir-rustflags-y
- Remove broken and unused modules.builtin(.modinfo) targets from
the top-level Makefile
- Add symbol size for kallsyms symbols that can change size
- modpost: Prevent leak when early return no suffix .o in
read_symbols()
- scripts/config: Update usage of POSIX sed
- 'make tags': Add support for rust source files and prevent binary
files from being analysed
- Several spelling mistakes and rephrasing
Kconfig updates
===============
* Add Julian Braha as Kconfig reviewer
* Fix submenu rendering of negative dependencies
* Minor changes:
- merge_config.sh: Keep temp file in the output dir
- Abort rather than loop for ever on EOF

modpost: use mod_warn() and mod_error(), clean up logging
Convert all module name logging to use the mod_warn() and mod_error() helpers, and pass the module to modpost_log() where used directly, to always have the module name prefixed in the log message, with .ko suffix for modules. Pass struct module *mod around in a few places instead of just mod->name. Further unify the logging while at it. Use single quotes instead of double quotes for symbols, sections, and namespaces. Explicitly state it's a "symbol" when referencing symbols.

modpost: add module as parameter to modpost_log()
modpost has a lot of error logging with module name, but the module name is logged in a plethora of ways. Add struct module * parameter to modpost_log(), and wrappers mod_warn() and mod_error(), to allow logging with a unified module name, if provided.

The Kconfig frontend should render options that depend on a previous option in the submenu of that previous option. But currently, this breaks for negative dependencies. For example, option FOO may be rendered in the submenu of option BAR, despite FOO actually depending on !BAR. Let's fix this ironic rendering by modifying Kconfig to explicitly check negative dependencies. I've only tested locally on x86, but as far as I can tell, this only changes how 2 options are rendered in the menu: 1. NTFS3_FS, no longer in the NTFS_FS submenu, and 2. MTD_BLOCK_RO, no longer in the MTD_BLOCK submenu.

kbuild: link-vmlinux.sh: improve detection of third pass requirement
It can happen that symbol sizes within .tmp_vmlinux1.kallsyms.o and
.tmp_vmlinux2.kallsyms.o differ, without affecting file size on disk
because of section alignment and/or padding emitted by the assembler.
link-vmlinux.sh doesn't detect this case currently and keeps using
.tmp_vmlinux2.kallsyms.o to link the final vmlinux. Due to the
different symbol sizes, other symbols are shifted within the final
image compared to .tmp_vmlinux2, and the final comparison of System.map
against "${kallsyms_sysmap}" fails with the message:
Inconsistent kallsyms data
Try "make KALLSYMS_EXTRA_PASS=1" as a workaround
This can happen in particular if the linker emits additional symbols
that might have different names between our (re-)linking steps, e.g.
because those names depend on the virtual address of the symbol. Linker
stubs for ARM errata work-arounds are one such case.
These changed symbol names can cause the output of the token
compression of kallsyms.c to change due to the changed symbol substring
count, which in turn can change the size of the kallsyms_names symbol
itself, causing the potential shift of subsequent symbol addresses in
.tmp_vmlinux2.kallsyms.o and therefore the final image.
Update link-vmlinux.sh to not rely on file size of
.tmp_vmlinux?.kallsyms.o alone but to also consider symbol offsets
within to resolve this, and do a third pass if required.

kconfig: abort rather than loop for ever on EOF
When a non-interactive 'make oldconfig' or 'syncconfig' meets a new int
or hex symbol whose default cannot be applied, conf_string() reads a
value from stdin. At end of file fgets() returns NULL, no value is set
and the loop asks again. The result is an endless loop which fills the
output until it exhausts memory, rather than a clean failure.
Detect this in conf_string(): if the value cannot be set and stdin is at
end of file, stop with an error that names the symbol.
Note that a symbol with no default doesn't trigger this, since
sym_calc_value() falls back to 0, which is accepted at end of file. The
loop is triggered by a broken Kconfig file, with a default whose text
fails sym_string_valid().
Such mistakes do creep in from time to time and are hard to debug, since
the build fills the log with repeated prompts instead of pointing at the
offending symbol. Some bad defaults draw a parse-time warning, but
menu_validate_number() accepts a reference to any int or hex symbol, so
a cross-type reference loops with no warning at all. For example, "0xff"
is not a valid int value:
config HEXSYM
hex
default 0xff
config VAL
int "Value"
default HEXSYM
Interactive use is unaffected, since feof() only becomes true once a
read actually hits end of file: an invalid answer at a terminal still
re-prompts, while Ctrl-D at such a prompt exits with the error instead
of looping. bool and tristate symbols and choices already accept the
default on an empty line, so they still take their defaults in a
non-interactive build.
Tested with int and hex symbols carrying such defaults: with empty
stdin, the code without this change produces around 190MB of repeated
prompts within two seconds, while with the change it exits 1 naming the
symbol. Piped and interactive (pty) sessions still re-prompt on an
invalid answer and then accept a valid one. A new string symbol with no
default still takes the empty string at end of file, since any text is
valid for a string.

scripts: headers_install.sh: Normalize __ASSEMBLY__ to __ASSEMBLER__
A previous patch to headers_install.sh normalized the usage of __ASSEMBLER__ to __ASSEMBLY__ in the UAPI headers due to two reasons: 1) There was the concern that the UAPI headers might be used with non-GCC-compatible compilers, which do not define __ASSEMBLER__ automatically. But other C compilers like PCC (see https://github.com/IanHarvey/pcc/blob/cvs2git/2018.09.20/cc/cc/cc.1#L405) and Tiny-C (see https://repo.or.cz/tinycc.git/commitdiff/a25325e9be13e52a), are defining __ASSEMBLER__ for compiling assembler files, too, so using it in UAPI header files should really be fine. 2) During the migration phase, the UAPI headers will use a mix of *both* __ASSEMBLY__ and __ASSEMBLER__ at the same time, which is ugly and inconsistent. That's true. But since we already shipped a couple of kernel versions that used __ASSEMBLER__ in the UAPI headers for certain architectures, we might now break user space programs that have been developed with these kernel versions if we switch back to __ASSEMBLY__. Thus let's better always use the macro that is defined by the compilers and standardize on __ASSEMBLER__ instead of __ASSEMBLY__ in all of the UAPI header files now.

kbuild: rpm-pkg: Preserve BTF sections in kernel modules during debuginfo stripping
After switching to the kernel's default package scripts for our local
kernel RPM builds, we noticed that module BTF entries were missing:
$ ls /sys/kernel/btf/
vmlinux <<<< only vmlinux, no module BTF
Root cause: find-debuginfo.sh (from the debugedit package) prefers
eu-strip over strip when elfutils is installed, which is the common
case on RHEL 9. eu-strip removes non-allocated ELF sections, including
the .BTF section that contains BPF Type Format information for kernel
modules. Without .BTF, BPF tools (bpftool, bcc, bpftrace) cannot resolve
kernel types at runtime, and /sys/kernel/btf/<module> entries are not
created when modules are loaded.

scripts/sorttable: Handle RISC-V patchable ftrace entries
RISC-V uses -fpatchable-function-entry=8,4 when the compressed ISA is
enabled and -fpatchable-function-entry=4,2 otherwise. In both cases, the
patchable NOP area starts 8 bytes before the function symbol address.
The __mcount_loc entries therefore point at the patchable NOP area
associated with a function, while nm reports the function symbol at the
entry address used for the function range check.
After RISC-V selected HAVE_BUILDTIME_MCOUNT_SORT, sorttable started
applying that range check at build time. Without allowing entries just
before the reported function address, the mcount sorter treats valid
RISC-V ftrace callsites as invalid weak-function entries and writes
them back as zero. The resulting kernel boots with no ftrace entries,
breaking dynamic ftrace and users such as livepatch.
The failure is silent during the final link because zeroing weak-function
entries is an expected sorttable operation. At boot, those zero entries
are skipped by ftrace_process_locs(), so the only obvious symptom is that
the vmlinux ftrace table has lost valid callsites and ftrace users cannot
attach to them.
CONFIG_FTRACE_SORT_STARTUP_TEST also reports the table as sorted in this
state: it only checks that the __mcount_loc entries are in ascending
order, which a fully zeroed table trivially satisfies. The original
commit relied on this check and did not see the regression.
On an affected RISC-V QEMU boot with both CONFIG_FTRACE_SORT_STARTUP_TEST
and CONFIG_FTRACE_STARTUP_TEST enabled, the sort check still passes
while ftrace reports zero usable entries and the early selftests fail:
[ 0.000000] ftrace section at ffffffff8101da98 sorted properly
[ 0.000000] ftrace: allocating 0 entries in 128 pages
[ 0.054999] Testing tracer function: .. no entries found ..FAILED!
[ 0.172407] tracer: function failed selftest, disabling
[ 0.178186] Failed to init function_graph tracer, init returned -19
Handle RISC-V like arm64 for the function-range check and allow
patchable entries up to 8 bytes before the function address.
With this fix, a RISC-V QEMU smoke boot with ftrace startup tests shows
the vmlinux ftrace table is populated and dynamic ftrace still works:
[ 0.000000] ftrace: allocating 46749 entries in 184 pages
[ 0.051115] Testing tracer function: PASSED
[ 1.283782] Testing dynamic ftrace: PASSED

SPDX patches for 7.2-rc1
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. All of these patches have been in linux-next for weeks with no reported problems.

rust: doctest: fix incorrect pattern in replacement
The `-> Result<(), impl core::fmt::Debug>` string is generated by rustdoc
and by adding "::" into the string it no longer finds anything, making
the line useless.
Remove the "::" in the pattern. Omit it in the replacement too, for
consistency with upstream rustdoc.
Fixes:

kconfig: add optional warnings for changed input values
When reading .config input, Kconfig stores user-provided values first and then resolves the final value after applying dependencies, ranges, and other constraints. If the final value differs from the user input, Kconfig already tracks that state internally, but it does not provide a focused diagnostic to show which explicit inputs were adjusted. This is particularly confusing for requested values that get forced down by unmet dependencies or clamped by ranges. Add an opt-in diagnostic controlled by KCONFIG_WARN_CHANGED_INPUT. Emit the warnings from conf_write() and conf_write_defconfig() after value resolution. Print the diagnostic to stderr directly, not through the normal message callback, so it remains visible when conf is run with -s, such as from make -s. Keep the diagnostic out of the conf_message() formatting buffer so long warning lists are not truncated, and mark processed symbols as written before the SYMBOL_WRITE check so duplicate menu nodes cannot emit duplicate warnings. Document the new environment variable and add tests for olddefconfig, savedefconfig, and the silent-conf path.

modpost: Ignore Clang LTO suffixes in symbol matching
When building the kernel with Clang ThinLTO enabled, the compiler can mangle static variable names by appending suffixes such as ".llvm.<hash>" to prevent naming collisions across translation units. This name mangling breaks the section mismatch whitelisting in modpost. modpost relies on glob patterns (e.g., "*_ops" or "*_probe") to identify safe references between permanent data and initialization code. Because the LTO suffix modifies the end of the symbol name, legitimately whitelisted structures fail the match, resulting in false positive warnings. For example, a static pernet_operations struct triggers the following: WARNING: modpost: vmlinux: section mismatch in reference: \ ping_v4_net_ops.llvm.5641696707737373282 (section: .data) -> \ ping_v4_proc_init_net (section: .init.text) Fix this by ignoring "*_ops.llvm.*" in "from" symbol names (the same as "*_ops").

treewide: fix transposed "sign" typos and update spelling.txt
Several comments transpose the letters in "assigned" and "unsigned", spelling them with "sing" instead of "sign". Correct all of them. Of these, the misspelling of "assigned" is not yet flagged by checkpatch, so also add it to scripts/spelling.txt. The remaining matches of `grep -ri singed` are RISINGEDGE register and enum names, not typos.

Devicetree updates for v7.2:
DT core:
- Add support for handling multiple cells in "iommu-map" entries.
- Support only 1 entry in /reserved-memory "reg" entries. Support for
more than 1 entry has been broken.
- Fix a UAF on alloc_reserved_mem_array() failure
- Make "ibm,phandle" handling logic specific to PPC
- Use memcpy() instead of strcpy() for known length strings
- Ensure __of_find_n_match_cpu_property() handles malformed "reg"
entries
- Add various checks that expected strings are strings before accessing
them
- Drop redundant memset() when unflattening DT
DT bindings:
- Add a DTS style checker. Currently hooked up to dt_binding_check to
check examples.
- Convert st,nomadik platform, ti,omap-dmm, and ti,irq-crossbar
bindings to DT schema
- Add Apple System Management Controller hwmon, Qualcomm Hamoa Embedded
Controller, Qualcomm IPQ6018 PWM controller, fsl,mc1323, Samsung
SOFEF01-M DDIC panel, Freescale i.MX53 Television Encoder, Samsung S2M
series PMIC extcon, and MT6365 PMIC AuxADC schemas
- Extend bindings for QCom Maili and Nord PDC, QCom Hali fastrpc,
qcom,eliza-imem, qcom,oryon-1-5 CPU, and MT6365 Keys
- Consolidate "sram" property definitions
- Fix constraints on "nvmem" properties which only contain phandles and
no arg cells
- Another pass of fixing "phandle-array" constraints
- Add Gira vendor prefix
