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.
Additionally, since commit

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
[ 6.275456] Testing tracer function_graph: PASSED

Pull 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.

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").

Pull NOHZ updates from Thomas Gleixner: - Fix a long standing TOCTOU in get_cpu_sleep_time_us() - Make the CPU offline NOHZ handling more robust by disabling NOHZ on the outgoing CPU early instead of creating unneeded state which needs to be undone. - Unify idle CPU time accounting instead of having two different accounting mechanisms. These two different mechanisms are not really independent, but the different properties can in the worst case cause that gloabl idle time can be observed going backwards. - Consolidate the idle/iowait time retrieval interfaces instead of converting back and forth between them. - Make idle interrupt time accounting more robust. The original code assumes that interrupt time accouting is enabled and therefore stops elapsing idle time while an interrupt is handled in NOHZ dyntick state. That assumption is not correct as interrupt time accounting can be disabled at compile and runtime. - Fix an accounting error between dyntick idle time and dyntick idle steal time. The stolen time is not accounted and therefore idle time becomes inaccurate. The stolen time is now accounted after the fact as there is no way to predict the steal time upfront. * tag 'timers-nohz-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip: sched/cputime: Handle dyntick-idle steal time correctly sched/cputime: Handle idle irqtime gracefully sched/cputime: Provide get_cpu_[idle|iowait]_time_us() off-case tick/sched: Consolidate idle time fetching APIs tick/sched: Account tickless idle cputime only when tick is stopped tick/sched: Remove unused fields tick/sched: Move dyntick-idle cputime accounting to cputime code tick/sched: Remove nohz disabled special case in cputime fetch tick/sched: Unify idle cputime accounting s390/time: Prepare to stop elapsing in dynticks-idle powerpc/time: Prepare to stop elapsing in dynticks-idle sched/cputime: Correctly support generic vtime idle time sched/cputime: Remove superfluous and error prone kcpustat_field() parameter sched/idle: Handle offlining first in idle loop tick/sched: Fix TOCTOU in nohz idle time fetch |

Pull timer core updates from Thomas Gleixner:
"Updates for the time/timer core subsystem:
- Harden the user space controllable hrtimer interfaces further to
protect against unpriviledged DoS attempts by arming timers in the
past.
- Add per-capacity hierarchies to the timer migration code to prevent
timer migration accross different capacity domains. This code has
been disabled last minute as there is a pathological problem with
SoCs which advertise a larger number of capacity domains. The
problem is under investigation and the code won't be active before
v7.3, but that turned out to be less intrusive than a full revert
as it preserves the preparatory steps and allows people to work on
the final resolution
- Export time namespace functionality as a recent user can be built
as a module.
- Initialize the jiffies clocksource before using it. The recent
hardening against time moving backward requires that the related
members of struct clocksource have been initialized, otherwise it
clamps the readout to 0, which makes time stand sill and causes
boot delays.
- Fix a more than twenty year old PID reference count leak in an
error path of the POSIX CPU timer code.
- The usual small fixes, improvements and cleanups all over the
place"

Pull interrupt core updates from Thomas Gleixner:
- Rework of /proc/interrupt handling:
/proc/interrupts was subject to micro optimizations for a long time,
but most of the low hanging fruit was left on the table. This rework
addresses the major time consuming issues:
- Printing a long series of zeros one by one via a format string
instead of counting subsequent zeros and emitting a string
constant.
- Simplify and cache the conditions whether interrupts should be
printed
- Use a proper iteration over the interrupt descriptor xarray
instead of walking and testing one by one.
- Provide helper functions for the architecture code to emit the
architecture specific counters
- Convert the counter structure in x86 to an array, which
simplifies the output and add mechanisms to suppress unused
architecture interrupts, which just occupy space for nothing.
Adopt the new core mechanisms.
This adjusts the gdb scripts related to interrupt counter statistics
to work with the new mechanisms.
- Prevent a string overflow in the /proc/irq/$N/ directory name
creation code.

Merge tag 'rust-7.2' of gitolite.kernel.org:pub/scm/linux/kernel/git/ojeda/linux
Pull 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.
Thanks everyone for stepping up!
And some other fixes, cleanups and improvements"

modpost: Handle malformed WMI GUID strings
Some WMI GUIDs found inside binary MOF files contain both uppercase and lowercase characters. Blindly copying such GUIDs will prevent the associated WMI driver from loading automatically because the WMI GUID found inside WMI device ids always contains uppercase characters. Avoid this issue by always converting WMI GUID strings to uppercase. Also verify that the WMI GUID string actually looks like a valid GUID.
