Pull networking fixes from Jakub Kicinski:
"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"

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.

Pull networking updates from Jakub Kicinski:
"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)

Pull Rust updates from Miguel Ojeda:
"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"

As proposed in the past in e.g. LPC 2025 and the Maintainers Summit [1],
we are going to follow Debian Stable's `bindgen` versions as our minimum
supported version.
Debian Trixie was released with `bindgen` 0.71.1, which it still uses
to this day [2].
Debian Trixie's release happened on 2025-08-09 [3], which means that a
fair amount of time has passed since its release for kernel developers
to upgrade.
Thus bump the minimum to the new version.
Then, in later commits, clean up most of the workarounds and other bits
that this upgrade of the minimum allows us.
Ubuntu 25.10 also has a recent enough `bindgen` [4] (even the already
unsupported Ubuntu 25.04 had it), and they also provide versioned packages
with `bindgen` 0.71.1 back to Ubuntu 24.04 LTS [5].

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].

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.

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. This patch adds a complete section
explaining how to figure the list of recipients to send the report to.

This clarifies the fact that the bug reporters must use a valid
e-mail address to send their report, and that the security team
assists developers working on a fix but doesn't always produce
fixes on its own.

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.

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.

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.
