SPDX change for 7.1-rc1
Here is a single SPDX-like change for 7.1-rc1. It explicitly allows the use of SPDX-FileCopyrightText which has been used already in many files. At the same time, update checkpatch to catch any "non allowed" spdx identifiers as we don't want to go overboard here. This has been in linux-next for a long time with no reported problems.

Including fixes from Netfilter.
Steady stream of fixes. Last two weeks feel comparable to the two
weeks before the merge window. Lots of AI-aided bug discovery.
A newer big source is Sashiko/Gemini (Roman Gushchin's system),
which points out issues in existing code during patch review
(maybe 25% of fixes here likely originating from Sashiko).
Nice thing is these are often fixed by the respective maintainers,
not drive-bys.
Current release - new code bugs:
- kconfig: MDIO_PIC64HPSC should depend on ARCH_MICROCHIP
Previous releases - regressions:
- add async ndo_set_rx_mode and switch drivers which we promised
to be called under the per-netdev mutex to it
- dsa: remove duplicate netdev_lock_ops() for conduit ethtool ops
- hv_sock: report EOF instead of -EIO for FIN
- vsock/virtio: fix MSG_PEEK calculation on bytes to copy
Previous releases - always broken:
- ipv6: fix possible UAF in icmpv6_rcv()
- icmp: validate reply type before using icmp_pointers
- af_unix: drop all SCM attributes for SOCKMAP
- netfilter: fix a number of bugs in the osf (OS fingerprinting)
- eth: intel: fix timestamp interrupt configuration for E825C
Misc:
- bunch of data-race annotations

Documentation/process: maintainer-soc: Document purpose of defconfigs
Common mistake in commit messages of patches on mailing list adding CONFIG options to arm/multi_v7 or arm64/defconfig is saying what that patch is doing, e.g. "Enable driver foo". That is obvious from the diff part, thus explaining it does not bring any value. What brings value is to understand why "driver foo" should be in a shared, upstream defconfig, especially considering that distros have their own defconfigs and we do not care about non-upstream trees.

Networking changes for 7.1.
Core & protocols
----------------
- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP.
- Number of code moves to help the compiler with inlining.
Avoid output arguments for returning drop reason where possible.
- Rework drop handling within qdiscs to include more metadata
about the reason and dropping qdisc in the tracepoints.
- Remove the rtnl_lock use from IP Multicast Routing.
- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two.
- Report TCP delayed ack timer information via socket diag.
- Add ip_local_port_step_width sysctl to allow distributing the randomly
selected ports more evenly throughout the allowed space.
- Add support for per-route tunsrc in IPv6 segment routing.
- Start work of switching sockopt handling to iov_iter.
- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up.
- Support MSG_EOR in MPTCP.
- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage.
- Remove UDP-Lite support (as announced in 2023).
- Remove support for building IPv6 as a module.
Remove the now unnecessary function calling indirection.
Cross-tree stuff
----------------
- Move Michael MIC code from generic crypto into wireless,
it's considered insecure but some WiFi networks still need it.
Netfilter
---------
- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.
Florian W reports this gets us ~13% higher packet rate.
- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex.
- Add more opinionated input validation to lower security exposure.
- Make IPVS hash tables to be per-netns and resizable.
Wireless
--------
- Finished assoc frame encryption/EPPKE/802.1X-over-auth.
- Radar detection improvements.
- Add 6 GHz incumbent signal detection APIs.
- Multi-link support for FILS, probe response templates and
client probing.
- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware.
Driver API
----------
- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs.
- Add standard counters for reporting pause storm events
(implement in mlx5 and fbnic).
- Add configuration API for completion writeback buffering
(implement in mana).
- Support driver-initiated change of RSS context sizes.
- Support DPLL monitoring input frequency (implement in zl3073x).
- Support per-port resources in devlink (implement in mlx5).
Misc
----
- Expand the YAML spec for Netfilter.

A busier cycle than I had expected for docs, including:
- Translations: some overdue updates to the Japanese translations, Chinese
translations for some of the Rust documentation, and the beginnings of a
Portuguese translation.
- New documents covering CPU isolation, managed interrupts, debugging
Python gbb scripts, and more.
- More tooling work from Mauro, reducing docs-build warnings, adding self
tests, improving man-page output, bringing in a proper C tokenizer to
replace (some of) the mess of kernel-doc regexes, and more.
- Update and synchronize changes.rst and scripts/ver_linux, and put both
into alphabetical order.
...and a long list of documentation updates, typo fixes, and general
improvements.

Rust changes for v7.1
Toolchain and infrastructure:
- Bump the minimum Rust version to 1.85.0 (and 'bindgen' to 0.71.1).
As proposed in LPC 2025 and the Maintainers Summit [1], we are going
to follow Debian Stable's Rust versions as our minimum versions.
Debian Trixie was released on 2025-08-09 with a Rust 1.85.0 and
'bindgen' 0.71.1 toolchain, which is a fair amount of time for e.g.
kernel developers to upgrade.
Other major distributions support a Rust version that is high enough
as well, including:
+ Arch Linux.
+ Fedora Linux.
+ Gentoo Linux.
+ Nix.
+ openSUSE Slowroll and openSUSE Tumbleweed.
+ Ubuntu 25.10 and 26.04 LTS. In addition, 24.04 LTS using
their versioned packages.
The merged patch series comes with the associated cleanups and
simplifications treewide that can be performed thanks to both bumps,
as well as documentation updates.
In addition, start using 'bindgen''s '--with-attribute-custom-enum'
feature to set the 'cfi_encoding' attribute for the 'lru_status' enum
used in Binder.
Link: https://lwn.net/Articles/1050174/ [1]
- Add experimental Kconfig option ('CONFIG_RUST_INLINE_HELPERS') that
inlines C helpers into Rust.
Essentially, it performs a step similar to LTO, but just for the
helpers, i.e. very local and fast.
It relies on 'llvm-link' and its '--internalize' flag, and requires
a compatible LLVM between Clang and 'rustc' (i.e. same major version,
'CONFIG_RUSTC_CLANG_LLVM_COMPATIBLE'). It is only enabled for two
architectures for now.
The result is a measurable speedup in different workloads that
different users have tested. For instance, for the null block driver,
it amounts to a 2%.
- Support global per-version flags.
While we already have per-version flags in many places, we didn't
have a place to set global ones that depend on the compiler version,
i.e. in 'rust_common_flags', which sometimes is needed to e.g. tweak
the lints set per version.
Use that to allow the 'clippy::precedence' lint for Rust < 1.86.0,
since it had a change in behavior.
- Support overriding the crate name and apply it to Rust Binder, which
wanted the module to be called 'rust_binder'.
- Add the remaining '__rust_helper' annotations (started in the
previous cycle).
'kernel' crate:
- Introduce the 'const_assert!' macro: a more powerful version of
'static_assert!' that can refer to generics inside functions or
implementation bodies, e.g.:
fn f<const N: usize>() {
const_assert!(N > 1);
}
fn g<T>() {
const_assert!(size_of::<T>() > 0, "T cannot be ZST");
}
In addition, reorganize our set of build-time assertion macros
('{build,const,static_assert}!') to live in the 'build_assert'
module.
Finally, improve the docs as well to clarify how these are different
from one another and how to pick the right one to use, and their
equivalence (if any) to the existing C ones for extra clarity.
- 'sizes' module: add 'SizeConstants' trait.
This gives us typed 'SZ_*' constants (avoiding casts) for use in
device address spaces where the address width depends on the hardware
(e.g. 32-bit MMIO windows, 64-bit GPU framebuffers, etc.), e.g.:
let gpu_heap = 14 * u64::SZ_1M;
let mmio_window = u32::SZ_16M;
- 'clk' module: implement 'Send' and 'Sync' for 'Clk' and thus simplify
the users in Tyr and PWM.
- 'ptr' module: add 'const_align_up'.
- 'str' module: improve the documentation of the 'c_str!' macro to
explain that one should only use it for non-literal cases (for the
other case we instead use C string literals, e.g. 'c"abc"').
- Disallow the use of 'CStr::{as_ptr,from_ptr}' and clean one such use
in the 'task' module.
- 'sync' module: finish the move of 'ARef' and 'AlwaysRefCounted'
outside of the 'types' module, i.e. update the last remaining
instances and finally remove the re-exports.
- 'error' module: clarify that 'from_err_ptr' can return 'Ok(NULL)',
including runtime-tested examples.
The intention is to hopefully prevent UB that assumes the result of
the function is not 'NULL' if successful. This originated from a case
of UB I noticed in 'regulator' that created a 'NonNull' on it.
Timekeeping:
- Expand the example section in the 'HrTimer' documentation.
- Mark the 'ClockSource' trait as unsafe to ensure valid values for
'ktime_get()'.
- Add 'Delta::from_nanos()'.
'pin-init' crate:
- Replace the 'Zeroable' impls for 'Option<NonZero*>' with impls of
'ZeroableOption' for 'NonZero*'.
- Improve feature gate handling for unstable features.
- Declutter the documentation of implementations of 'Zeroable' for
tuples.
- Replace uses of 'addr_of[_mut]!' with '&raw [mut]'.
rust-analyzer:
- Add type annotations to 'generate_rust_analyzer.py'.
- Add support for scripts written in Rust ('generate_rust_target.rs',
'rustdoc_test_builder.rs', 'rustdoc_test_gen.rs').
- Refactor 'generate_rust_analyzer.py' to explicitly identify host and
target crates, improve readability, and reduce duplication.
And some other fixes, cleanups and improvements.

Debian Trixie was released with a Rust 1.85.0 toolchain [2], which it still uses to this day [3] (i.e. no update to Rust 1.85.1).

Then, in later commits, clean up most of the workarounds and other bits that this upgrade of the minimum allows us. pin-init was left as-is since the patches come from upstream. And the vendored crates are unmodified, since we do not want to change those. Note that the minimum LLVM major version for Rust 1.85.0 is LLVM 18 (the Rust upstream binaries use LLVM 19.1.7), thus e.g. `RUSTC_LLVM_VERSION` tests can also be updated, but there are no suitable ones to simplify. Ubuntu 25.10 also has a recent enough Rust toolchain [5], and they also provide versioned packages with a Rust 1.85.1 toolchain even back to Ubuntu 22.04 LTS [6].

Documentation: fix two typos in latest update to the security report howto
In previous patch "Documentation: clarify the mandatory and desirable info for security reports" I left two typos that I didn't detect in local checks. One is "get_maintainers.pl" (no 's' in the script name), and the other one is a missing closing quote after "Reported-by", which didn't have effect here but I don't know if it can break rendering elsewhere (e.g. on the public HTML page). Better fix it before it gets merged.

Documentation: clarify the mandatory and desirable info for security reports
A significant part of the effort of the security team consists in begging reporters for patch proposals, or asking them to provide them in regular format, and most of the time they're willing to provide this, they just didn't know that it would help. So let's add a section detailing the required and desirable contents in a security report to help reporters write more actionable reports which do not require round trips.

These days, 80% of the work done by the security team consists in locating the affected subsystem in a report, running get_maintainers on it, forwarding the report to these persons and responding to the reporter with them in Cc. This is a huge and unneeded overhead that we must try to lower for a better overall efficiency.

LICENSES: Explicitly allow SPDX-FileCopyrightText
Sources already have SPDX-FileCopyrightText (~40 instances) and more appear on the mailing list, so document that it is allowed. On the other hand SPDX defines several other tags like SPDX-FileType, so add checkpatch rule to narrow desired tags only to two of them - license and copyright. That way no new tags would sneak in to the kernel unnoticed.

docs: netdev: refine netdevsim testing guidance
The library to create tests for both NIC HW and netdevsim has existed for almost a year. netdevsim-only tests we get increasingly feel like a waste, we should try to write tests that work both on netdevsim and real HW. Refine the guidance accordingly. Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/20260304151647.2770466-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

docs: handling-regressions: add, trim, and sort quotes from Linus
Add additional quotes from Linus while trimming the existing ones and sorting them all into categories. That makes it easier for new developers and maintainers to look up how Linus expects certain situations wrt regressions to be handled. The earlier sections in the document already explain this, but those parts are often questioned -- or not considered authoritative at all and plainly ignored. Having it straight from the horse's mouth helps get everyone on the same page, even if that makes the document quite a bit longer (the raw line count of this section doubles, but the number of characters increases by nearly 50%). In return, this covers a lot more aspects and, due to the sub-headings, is easier to navigate. In contrast to the more neutral description in the early sections of the document, this also provides a better insight into how serious Linus is about the "no regressions" rule and how he wants it to be interpreted in practice; this makes it easier for new developers and maintainers to understand things and prevent run-ins with higher-level maintainers.

Rust changes for v6.20 / v7.0
Toolchain and infrastructure:
- Add '__rust_helper' annotation to the C helpers.
This is needed to inline these helpers into Rust code.
- Remove imports available via the prelude, treewide.
This was possible thanks to a new lint in Klint that Gary has
implemented -- more Klint-related changes, including initial upstream
support, are coming.
- Deduplicate pin-init flags.
'kernel' crate:
- Add support for calling a function exactly once with the new
'do_once_lite!' macro (and 'OnceLite' type).
Based on this, add 'pr_*_once!' macros to print only once.
- Add 'impl_flags!' macro for defining common bitflags operations:
impl_flags!(
/// Represents multiple permissions.
#[derive(Debug, Clone, Default, Copy, PartialEq, Eq)]
pub struct Permissions(u32);
/// Represents a single permission.
#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub enum Permission {
/// Read permission.
Read = 1 << 0,
/// Write permission.
Write = 1 << 1,
/// Execute permission.
Execute = 1 << 2,
}
);
let mut f: Permissions = Permission::Read | Permission::Write;
assert!(f.contains(Permission::Read));
assert!(!f.contains(Permission::Execute));
f |= Permission::Execute;
assert!(f.contains(Permission::Execute));
let f2: Permissions = Permission::Write | Permission::Execute;
assert!((f ^ f2).contains(Permission::Read));
assert!(!(f ^ f2).contains(Permission::Write));
- 'bug' module: support 'CONFIG_DEBUG_BUGVERBOSE_DETAILED' in the
'warn_on!' macro in order to show the evaluated condition alongside
the file path:
------------[ cut here ]------------
WARNING: [val == 1] linux/samples/rust/rust_minimal.rs:27 at ...
Modules linked in: rust_minimal(+)
- Add safety module with 'unsafe_precondition_assert!' macro, currently
a wrapper for 'debug_assert!', intended to mark the validation of
safety preconditions where possible:
/// # Safety
///
/// The caller must ensure that `index` is less than `N`.
unsafe fn set_unchecked(&mut self, index: usize, value: T) {
unsafe_precondition_assert!(
index < N,
"set_unchecked() requires index ({index}) < N ({N})"
);
...
}
- Add instructions to 'build_assert!' documentation requesting to
always inline functions when used with function arguments.
- 'ptr' module: replace 'build_assert!' with a 'const' one.
- 'rbtree' module: reduce unsafe blocks on pointer derefs.
- 'transmute' module: implement 'FromBytes' and 'AsBytes' for
inhabited ZSTs, and use it in Nova.
- More treewide replacements of 'c_str!' with C string literals.
'macros' crate:
- Rewrite most procedural macros ('module!', 'concat_idents!',
'#[export]', '#[vtable]', '#[kunit_tests]') to use the 'syn' parsing
library which we introduced last cycle, with better diagnostics.
This also allows to support '#[cfg]' properly in the '#[vtable]'
macro, to support arbitrary types in 'module!' macro (not just an
identifier) and to remove several custom parsing helpers we had.
- Use 'quote!' from the recently vendored 'quote' library and remove
our custom one.
The vendored one also allows us to avoid quoting '"' and '{}' inside
the template anymore and editors can now highlight it. In addition,
it improves robustness as it eliminates the need for string quoting
and escaping.
- Use 'pin_init::zeroed()' to simplify KUnit code.
'pin-init' crate:
- Rewrite all procedural macros ('[pin_]init!', '#[pin_data]',
'#[pinned_drop]', 'derive([Maybe]Zeroable)') to use the 'syn' parsing
library which we introduced last cycle, with better diagnostics.
- Implement 'InPlaceWrite' for '&'static mut MaybeUninit<T>'. This
enables users to use external allocation mechanisms such as
'static_cell'.
- Support tuple structs in 'derive([Maybe]Zeroable)'.
- Support attributes on fields in '[pin_]init!' (such as
'#[cfg(...)]').
- Add a '#[default_error(<type>)]' attribute to '[pin_]init!' to
override the default error (when no '? Error' is specified).
- Support packed structs in '[pin_]init!' with
'#[disable_initialized_field_access]'.
- Remove 'try_[pin_]init!' in favor of merging their feature
with '[pin_]init!'. Update the kernel's own 'try_[pin_]init!'
macros to use the 'default_error' attribute.
- Correct 'T: Sized' bounds to 'T: ?Sized' in the generated
'PinnedDrop' check by '#[pin_data]'.
Documentation:
- Conclude the Rust experiment.
MAINTAINERS:
- Add "RUST [RUST-ANALYZER]" entry for the rust-analyzer support. Tamir
and Jesung will take care of it. They have both been active around it
for a while. The new tree will flow through the Rust one.
- Add Gary as maintainer for "RUST [PIN-INIT]".
- Update Boqun and Tamir emails to their kernel.org accounts.
And a few other cleanups and improvements.

A slightly calmer cycle for docs this time around, though there is still a
fair amount going on, including:
- Some signs of life on the long-moribund Japanese translation
- Documentation on policies around the use of generative tools for patch
submissions, and a separate document intended for consumption by
generative tools.
- The completion of the move of the documentation tools to tools/docs. For
now we're leaving a /scripts/kernel-doc symlink behind to avoid breaking
scripts.
- Ongoing build-system work includes the incorporation of documentation in
Python code, better support for documenting variables, and lots of

Documentation: use a source-read extension for the index link boilerplate
The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

Documentation: Provide guidelines for tool-generated content
In the last few years, the capabilities of coding tools have exploded. As those capabilities have expanded, contributors and maintainers have more and more questions about how and when to apply those capabilities. Add new Documentation to guide contributors on how to best use kernel development tools, new and old. Note, though, there are fundamentally no new or unique rules in this new document. It clarifies expectations that the kernel community has had for many years. For example, researchers are already asked to disclose the tools they use to find issues by Documentation/process/researcher-guidelines.rst. This new document just reiterates existing best practices for development tooling. In short: Please show your work and make sure your contribution is easy to review.

rust: conclude the Rust experiment
The Rust support was merged in v6.1 into mainline in order to help determine whether Rust as a language was suitable for the kernel, i.e. worth the tradeoffs, technically, procedurally and socially. At the 2025 Linux Kernel Maintainers Summit, the experiment has just been deemed concluded [1]. Thus remove the section -- it was not fully true already anyway, since there are already uses of Rust in production out there, some well-known Linux distributions enable it and it is already in millions of devices via Android. Obviously, this does not mean that everything works for every kernel configuration, architecture, toolchain etc., or that there won't be new issues. There is still a ton of work to do in all areas, from the kernel to upstream Rust, GCC and other projects. And, in fact, certain combinations (such as the mixed GCC+LLVM builds and the upcoming GCC support) are still quite experimental but getting there. But the experiment is done, i.e. Rust is here to stay. I hope this signals commitment from the kernel to companies and other entities to invest more into it, e.g. into giving time to their kernel developers to train themselves in Rust. Thanks to the many kernel maintainers that gave the project their support and patience throughout these years, and to the many other developers, whether in the kernel or in other projects, that have made this possible. I had a long list of 173 names in the credits of the original pull that merged the support into the kernel [2], and now such a list would be way longer, so I will not even try to compose one, but again, thanks a lot, everybody.
