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)

   - Support per-port resources in devlink (implement in mlx5)

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"

Then, in later commits, clean up most of the workarounds and other bits

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.
