New code for 6.9:
* Online Repair;
** New ondisk structures being repaired.
- Inode's mode field by trying to obtain file type value from the a
directory entry.
- Quota counters.
- Link counts of inodes.
- FS summary counters.
- rmap btrees.
Support for in-memory btrees has been added to support repair of rmap
btrees.
** Misc changes
- Report corruption of metadata to the health tracking subsystem.
- Enable indirect health reporting when resources are scarce.
- Reduce memory usage while reparing refcount btree.
- Extend "Bmap update" intent item to support atomic extent swapping on
the realtime device.
- Extend "Bmap update" intent item to support extended attribute fork and
unwritten extents.
** Code cleanups
- Bmap log intent.
- Btree block pointer checking.
- Btree readahead.
- Buffer target.
- Symbolic link code.
* Remove mrlock wrapper around the rwsem.
* Convert all the GFP_NOFS flag usages to use the scoped
memalloc_nofs_save() API instead of direct calls with the GFP_NOFS.
* Refactor and simplify xfile abstraction. Lower level APIs in
shmem.c are required to be exported in order to achieve this.
* Skip checking alignment constraints for inode chunk allocations when block
size is larger than inode chunk size.
* Do not submit delwri buffers collected during log recovery when an error
has been encountered.
* Fix SEEK_HOLE/DATA for file regions which have active COW extents.
* Fix lock order inversion when executing error handling path during
shrinking a filesystem.
* Remove duplicate ifdefs.

Networking changes for 6.9.
Core & protocols
----------------
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps etc.)
lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core
instead of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length
and budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global config
variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug
of ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for
use on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code
--------------------------------------------
- Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena).
- Rework selftest harness to enable the use of the full range of
ksft exit code (pass, fail, skip, xfail, xpass).
Netfilter
---------
- Allow userspace to define a table that is exclusively owned by a daemon
(via netlink socket aliveness) without auto-removing this table when
the userspace program exits. Such table gets marked as orphaned and
a restarting management daemon can re-attach/regain ownership.
- Speed up element insertions to nftables' concatenated-ranges set type.
Compact a few related data structures.
BPF
---
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between BPF
program and user space where structures inside the arena can have
pointers to other areas of the arena, and pointers work seamlessly
for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the verifier
and the program. The verifier allows the program to loop assuming it's
behaving well, but reserves the right to terminate it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF objects.
Wireless
--------
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API
----------
- Major overhaul of the Energy Efficient Ethernet internals to support
new link modes (2.5GE, 5GE), share more code between drivers
(especially those using phylib), and encourage more uniform behavior.
Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc
----
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions,
and packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message encapsulation
or "Netlink polymorphism", where interpretation of nested attributes
depends on link type, classifier type or some other "class type".

A moderatly busy cycle for development this time around.
- Some cleanup of the main index page for easier navigation
- Rework some of the other top-level pages for better readability and, with
luck, fewer merge conflicts in the future.
- Submit-checklist improvements, hopefully the first of many.
- New Italian translations
- A fair number of kernel-doc fixes and improvements. We have also dropped
the recommendation to use an old version of Sphinx.
- A new document from Thorsten on bisection
...and lots of fixes and updates.

Pull hardening updates from Kees Cook:
"As is pretty normal for this tree, there are changes all over the
place, especially for small fixes, selftest improvements, and improved
macro usability.
Some header changes ended up landing via this tree as they depended on
the string header cleanups. Also, a notable set of changes is the work
for the reintroduction of the UBSAN signed integer overflow sanitizer
so that we can continue to make improvements on the compiler side to
make this sanitizer a more viable future security hardening option.

asm-generic updates for 6.9
Just two small updates this time:
- A series I did to unify the definition of PAGE_SIZE through Kconfig,
intended to help with a vdso rework that needs the constant but
cannot include the normal kernel headers when building the compat
VDSO on arm64 and potentially others.
- a patch from Yan Zhao to remove the pfn_to_virt() definitions from
a couple of architectures after finding they were both incorrect
and entirely unused.

SoC: device tree updates for 6.9
There is very little going on with new SoC support this time, all the
new chips are variations of others that we already support, and they
are all based on ARMv8 cores:
- Mediatek MT7981B (Filogic 820) and MT7988A (Filogic 880) are
networking SoCs designed to be used in wireless routers, similar
to the already supported MT7986A (Filogic 830).
- NXP i.MX8DXP is a variant of i.MX8QXP, with two CPU cores less.
These are used in many embedded and industrial applications.
- Renesas R8A779G2 (R-Car V4H ES2.0) and R8A779H0 (R-Car V4M)
are automotive SoCs.
- TI J722S is another automotive variant of its K3 family,
related to the AM62 series.
There are a total of 7 new arm32 machines and 45 arm64 ones, including
- Two Android phones based on the old Tegra30 chip
- Two machines using Cortex-A53 SoCs from Allwinner, a mini PC and
a SoM development board
- A set-top box using Amlogic Meson G12A S905X2
- Eight embedded board using NXP i.MX6/8/9
- Three machines using Mediatek network router chips
- Ten Chromebooks, all based on Mediatek MT8186
- One development board based on Mediatek MT8395 (Genio 1200)
- Seven tablets and phones based on Qualcomm SoCs, most of them
from Samsung.
- A third development board for Qualcomm SM8550 (Snapdragon 8 Gen 2)
- Three variants of the "White Hawk" board for Renesas
automotive SoCs
- Ten Rockchips RK35xx based machines, including NAS, Tablet,
Game console and industrial form factors.
- Three evaluation boards for TI K3 based SoCs
The other changes are mainly the usual feature additions for existing hardware,
cleanups, and dtc compile time fixes. One notable change is the inclusion
of PowerVR SGX GPU nodes on TI SoCs.

Core x86 changes for v6.9:
- The biggest change is the rework of the percpu code,
to support the 'Named Address Spaces' GCC feature,
by Uros Bizjak:
- This allows C code to access GS and FS segment relative
memory via variables declared with such attributes,
which allows the compiler to better optimize those accesses
than the previous inline assembly code.
- The series also includes a number of micro-optimizations
for various percpu access methods, plus a number of
cleanups of %gs accesses in assembly code.
- These changes have been exposed to linux-next testing for
the last ~5 months, with no known regressions in this area.
- Fix/clean up __switch_to()'s broken but accidentally
working handling of FPU switching - which also generates
better code.
- Propagate more RIP-relative addressing in assembly code,
to generate slightly better code.
- Rework the CPU mitigations Kconfig space to be less idiosyncratic,
to make it easier for distros to follow & maintain these options.
- Rework the x86 idle code to cure RCU violations and
to clean up the logic.
- Clean up the vDSO Makefile logic.
- Misc cleanups and fixes.
[ Please note that there's a higher number of merge commits in
this branch (three) than is usual in x86 topic trees. This happened
due to the long testing lifecycle of the percpu changes that
involved 3 merge windows, which generated a longer history
and various interactions with other core x86 changes that we
felt better about to carry in a single branch. ]

Rust changes for v6.9
Another routine one in terms of features. We got two version upgrades
this time, but in terms of lines, 'alloc' changes are not very large.
Toolchain and infrastructure:
- Upgrade to Rust 1.76.0.
This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. These allow us to remove two
more unstable features ('const_maybe_uninit_zeroed' and
'ptr_metadata') from the list, among other improvements.
- Mark 'rustc' (and others) invocations as recursive, which fixes a new
warning and prepares us for the future in case we eventually take
advantage of the Make jobserver.
'kernel' crate:
- Add the 'container_of!' macro.
- Stop using the unstable 'ptr_metadata' feature by employing the now
stable 'byte_sub' method to implement 'Arc::from_raw()'.
- Add the 'time' module with a 'msecs_to_jiffies()' conversion function
to begin with, to be used by Rust Binder.
- Add 'notify_sync()' and 'wait_interruptible_timeout()' methods to
'CondVar', to be used by Rust Binder.
- Update integer types for 'CondVar'.
- Rename 'wait_list' field to 'wait_queue_head' in 'CondVar'.
- Implement 'Display' and 'Debug' for 'BStr'.
- Add the 'try_from_foreign()' method to the 'ForeignOwnable' trait.
- Add reexports for macros so that they can be used from the right
module (in addition to the root).
- A series of code documentation improvements, including adding
intra-doc links, consistency improvements, typo fixes...
'macros' crate:
- Place generated 'init_module()' function in '.init.text'.
Documentation:
- Add documentation on Rust doctests and how they work.

docs: drop the version constraints for sphinx and dependencies
As discussed (see Links), there is some inertia to move to the recent Sphinx versions for the doc build environment. As first step, drop the version constraints and the related comments. As sphinx depends on jinja2, jinja2 is pulled in automatically. So drop that. Then, the sphinx-pre-install script will fail though with: Can't get default sphinx version from ./Documentation/sphinx/requirements.txt at ./scripts/sphinx-pre-install line 305. The script simply expects to parse a version constraint with Sphinx in the requirements.txt. That version is used in the script for suggesting the virtualenv directory name. To suggest a virtualenv directory name, when there is no version given in the requirements.txt, one could try to guess the version that would be downloaded with 'pip install -r Documentation/sphinx/requirements.txt'. However, there seems no simple way to get that version without actually setting up the venv and running pip. So, instead, name the directory with the fixed name 'sphinx_latest'. Finally update the Sphinx build documentation to reflect this directory name change.

coccinelle: semantic patch to check for potential struct_size calls
include/linux/overflow.h includes helper macros intended for calculating sizes of allocations. These macros prevent accidental overflow by saturating at SIZE_MAX. In general when calculating such sizes use of the macros is preferred. Add a semantic patch which can detect code patterns which can be replaced by struct_size. Note that I set the confidence to medium because this patch doesn't make an attempt to ensure that the relevant array is actually a flexible array. The struct_size macro does specifically require a flexible array. In many cases the detected code could be refactored to a flexible array, but this is not always possible (such as if there are multiple over-allocations).

kbuild: mark rustc (and others) invocations as recursive
`rustc` (like Cargo) may take advantage of the jobserver at any time (e.g. for backend parallelism, or eventually frontend too). In the kernel, we call `rustc` with `-Ccodegen-units=1` (and `-Zthreads` is 1 so far), so we do not expect parallelism. However, in the upcoming Rust 1.76.0, a warning is emitted by `rustc` [1] when it cannot connect to the jobserver it was passed (in many cases, but not all: compiling and `--print sysroot` do, but `--version` does not). And given GNU Make always passes the jobserver in the environment variable (even when a line is deemed non-recursive), `rustc` will end up complaining about it (in particular in Make 4.3 where there is only the simple pipe jobserver style). One solution is to remove the jobserver from `MAKEFLAGS`. However, we can mark the lines with calls to `rustc` (and Cargo) as recursive, which looks simpler. This is being documented as a recommendation in `rustc` [2] and allows us to be ready for the time we may use parallelism inside `rustc` (potentially now, if a user passes `-Zthreads`). Thus do so. Similarly, do the same for `rustdoc` and `cargo` calls. Finally, there is one case that the solution does not cover, which is the `$(shell ...)` call we have. Thus, for that one, set an empty `MAKEFLAGS` environment variable.

kernel-doc: Add unary operator * to $type_param_ref
In kernel-doc comments, unary operator * collides with Sphinx/
docutil's markdown for emphasizing.
This resulted in additional warnings from "make htmldocs":
WARNING: Inline emphasis start-string without end-string.
, as reported recently [1].
Those have been worked around either by escaping * (like \*param) or by
using inline-literal form of ``*param``, both of which are specific
to Sphinx/docutils.
Such workarounds are against the kenrel-doc's ideal and should better
be avoided.
Instead, add "*" to the list of unary operators kernel-doc recognizes
and make the form of *@param available in kernel-doc comments.

locking/atomic: scripts: Clarify ordering of conditional atomics
Conditional atomic operations (e.g. cmpxchg()) only provide ordering
when the condition holds; when the condition does not hold, the location
is not modified and relaxed ordering is provided. Where ordering is
needed for failed conditional atomics, it is necessary to use
smp_mb__before_atomic() and/or smp_mb__after_atomic().
This is explained tersely in memory-barriers.txt, and is implied but not
explicitly stated in the kerneldoc comments for the conditional
operations. The lack of an explicit statement has lead to some off-list
queries about the ordering semantics of failing conditional operations,
so evidently this is confusing.
Update the kerneldoc comments to explicitly describe the lack of ordering
for failed conditional atomic operations.
For most conditional atomic operations, this is written as:
| If (${condition}), atomically updates @v to (${new}) with ${desc_order} ordering.
| Otherwise, @v is not modified and relaxed ordering is provided.
For the try_cmpxchg() operations, this is written as:
| If (${condition}), atomically updates @v to @new with ${desc_order} ordering.
| Otherwise, @v is not modified, @old is updated to the current value of @v,
| and relaxed ordering is provided.

kbuild: Add -Wa,--fatal-warnings to as-instr invocation
Certain assembler instruction tests may only induce warnings from the assembler on an unsupported instruction or option, which causes as-instr to succeed when it was expected to fail. Some tests workaround this limitation by additionally testing that invalid input fails as expected. However, this is fragile if the assembler is changed to accept the invalid input, as it will cause the instruction/option to be unavailable like it was unsupported even when it is. Use '-Wa,--fatal-warnings' in the as-instr macro to turn these warnings into hard errors, which avoids this fragility and makes tests more robust and well formed.

scripts/kernel-doc: reindent
This file is using an ungodly mixture of 4 spaces, 2-wide tabs, 4-wide
tabs, _and_ 8-wide tabs, making it really hard to find good editor
settings for working with this file.
Bite the bullet and reindent it by hand. I tried using both perltidy
and vim, but neither of them were up to the task without changing too
much or getting confused about what they were supposed to be doing.
I did change a few instances of
}
else
into
} else
(and same for elsif); the file is again written using both styles, and
I left functions which already seemed self-consistent alone.
You can verify that this commit only changes whitespace using e.g.:
git diff --ignore-all-space --word-diff
or to see (only) the instances where newlines were added/removed:
git diff --ignore-all-space
You can also see the delta from what perltidy would have wanted to
do to this file (when asked to only indent it), which isn't that much
in the end:
perltidy -io -fnl scripts/kernel-doc
git diff --no-index scripts/kernel-doc{,.tdy}
