Documentation/CoC: Spell out the TAB role in enforcement decisions
Updates the document to clearly describe the scope and role the TAB plays
in making decisions on unresolved violations. If and when the CoC has to
make a call on instituting a ban, it doesn't act without the TAB's approval
and only when the TAB approves it with 2/3 vote in favor of the measure.
These changes ensure that the TAB role and its oversight on CoC measures
is consistently described throughout the document.

docs: netdev: add a note on selftest posting
We haven't had much discussion on the list about this, but a handful of people have been confused about rules on posting selftests for fixes, lately. I tend to post fixes with their respective selftests in the same series. There are tradeoffs around size of the net tree and conflicts but so far it hasn't been a major issue.

kernel-docs: Add book to process/kernel-docs.rst
Add a reference to my new book, The Linux Memory Manager, an in-depth exploration of the memory management subsystem, to process/kernel-docs.rst. This is not yet published, but the full draft is available on pre-order, so it seems worthwhile adding it here. The situation is made clear in the 'notes' section. The 'pre-release' was made available in February 2025, and full release is scheduled for Fall 2025. The book's ISBN-13 is 978-1718504462. The document will be updated upon release to reflect this.

Networking changes for 6.14.
Core
----
- More core refactoring to reduce the RTNL lock contention,
including preparatory work for the per-network namespace RTNL lock,
replacing RTNL lock with a per device-one to protect NAPI-related
net device data and moving synchronize_net() calls outside such
lock.
- Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and
more specific TCP coverage.
- Reduce network namespace tear-down time by removing per-subsystems
synchronize_net() in tipc and sched.
- Add flow label selector support for fib rules, allowing traffic
redirection based on such header field.
Netfilter
---------
- Do not remove netdev basechain when last device is gone, allowing
netdev basechains without devices.
- Revisit the flowtable teardown strategy, dealing better with fin,
reset and re-open events.
- Scale-up IP-vs connection dumping by avoiding linear search on
each restart.
Protocols
---------
- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core
- Better scaling of ICMP rate-limiting, by removing false-sharing in
inet peers handling.
- Introduces netlink notifications for multicast IPv4 and IPv6
address changes.
- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.
- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets,
to avoid local port exhaustion issues when the average connection
lifetime is very short.
- Support updating keys (re-keying) for connections using kernel
TLS (for TLS 1.3 only).
- Support ipv4-mapped ipv6 address clients in smc-r v2.
- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.
- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.
Driver API
----------
- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.
- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.
- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W implementation.
- Consolidate DSA drivers Energy Efficiency Ethernet support.
- Add EEE management to phylink, making use of the phylib
implementation.
- Add phylib support for in-band capabilities negotiation.
- Simplify how phylib-enabled mac drivers expose the supported
interfaces.
Tests and tooling
-----------------
- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.
- Increase TCP selftest coverage importing several packetdrill
test-cases.
- Regenerate the ethtool uapi header from the YNL spec,
to ease maintenance and future development.
- Add YNL support for decoding the link types used in net
self-tests, allowing a single build to run both net and
drivers/net.

reset and re-open events.
- Scale-up IP-vs connection dumping by avoiding linear search on each
restart.
Protocols:
- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core

address changes.
- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.
- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
avoid local port exhaustion issues when the average connection
lifetime is very short.

(for TLS 1.3 only).
- Support ipv4-mapped ipv6 address clients in smc-r v2.
- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.
- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.
Driver API:
- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.
- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.
- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W
implementation.
- Consolidate DSA drivers Energy Efficiency Ethernet support.
- Add EEE management to phylink, making use of the phylib
implementation.
- Add phylib support for in-band capabilities negotiation.
- Simplify how phylib-enabled mac drivers expose the supported
interfaces.
Tests and tooling:
- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.
- Increase TCP selftest coverage importing several packetdrill
test-cases.
- Regenerate the ethtool uapi header from the YNL spec, to ease
maintenance and future development.

docs: submitting-patches: clarify that signers may use their discretion on tags
Tags are really appreciated by maintainers in general, since it means someone is willing to put their name on a commit, be it as a reviewer, tester, etc. However, signers (i.e. submitters carrying tags from previous versions and maintainers applying patches) may need to take or drop tags, on a case-by-case basis, for different reasons. Yet this is not explicitly spelled out in the documentation, thus there may be instances [1] where contributors may feel unwelcome. Thus, to clarify, state this clearly.

docs: submitting-patches: clarify difference between Acked-by and Reviewed-by
Newcomers to the kernel need to learn the different tags that are used in commit messages and when to apply them. Acked-by is sometimes misunderstood, since the documentation did not really clarify (up to the previous commit) when it should be used, especially compared to Reviewed-by. The previous commit already clarified who the usual providers of Acked-by tags are, with examples. Thus provide a clarification paragraph for the comparison with Reviewed-by, and give a couple examples reusing the cases given above, in the previous commit.

docs: submitting-patches: clarify Acked-by and introduce "# Suffix"
Acked-by is typically used by maintainers. However, sometimes it is
useful to be able to accept the tag from other stakeholders that may not
have done a deep technical review or may not be kernel developers. For
instance:
- People with domain knowledge, such as the original author of the
code being modified.
- Userspace-side reviewers for a kernel uAPI patch, like in DRM --
see Documentation/gpu/drm-uapi.rst:
> The userspace-side reviewer should also provide an Acked-by on the
> kernel uAPI patch indicating that they believe the proposed uAPI
> is sound and sufficiently documented and validated for userspace's
> consumption.
- Key users of a feature, such as in [1].
Thus clarify that Acked-by may be used by other stakeholders (but most
commonly by maintainers).
Since, in these cases, it may be confusing why an Acked-by is/was
provided, allow and suggest to provide a "# Suffix" explaining it.
The "# Suffix" for Acked-by is already being used to clarify what part
of the patch a maintainer is acknowledging, thus also mention "# Suffix"
in the relevant paragraph.

kheaders: use 'tar' instead of 'cpio' for copying files
The 'cpio' command is used solely for copying header files to the
temporary directory. However, there is no strong reason to use 'cpio'
for this purpose. For example, scripts/package/install-extmod-build
uses the 'tar' command to copy files.
This commit replaces the use of 'cpio' with 'tar' because 'tar' is
already used in this script to generate kheaders_data.tar.xz anyway.
Performance-wide, there is no significant difference between 'cpio'
and 'tar'.
[Before]
$ rm -fr kheaders; mkdir kheaders
$ time sh -c '

find "$f" -name "*.h"

Align git commit ID abbreviation guidelines and checks
The guidelines for git commit ID abbreviation are inconsistent: some
places state to use 12 characters exactly, while other places recommend
12 characters or more. The same issue is present in the checkpatch.pl
script.
E.g. Documentation/dev-tools/checkpatch.rst says:
**GIT_COMMIT_ID**
The proper way to reference a commit id is:
commit <12+ chars of sha1> ("<title line>")
However, scripts/checkpatch.pl has two different checks: one warning
check accepting 12 characters exactly:
# Check Fixes: styles is correct
Please use correct Fixes: style 'Fixes: <12 chars of sha1> (\"<title line>\")'
and a second error check accepting 12-40 characters:
# Check for git id commit length and improperly formed commit descriptions
# A correctly formed commit description is:
# commit <SHA-1 hash length 12+ chars> ("Complete commit subject")
Please use git commit description style 'commit <12+ chars of sha1>
Hence patches containing commit IDs with more than 12 characters are
flagged by checkpatch, and sometimes rejected by maintainers or
reviewers. This is becoming more important with the growth of the
repository, as git may decide to use more characters in case of local
conflicts.
Fix this by settling on at least 12 characters, in both the
documentation and in the checkpatch.pl script.
Fixes:

docs: remove Documentation/dontdiff
The dontdiff file is a relic from the pre-Git era that has little use now. It has entries (parse.c, for example) that will mask real changes to kernel source files. There are all kinds of entries for files we do not create anymore. Rather than try to fix it up, simply remove it. Update the kernel documentation (and translations) to remove references to this file. There is an ancient Japanese translation of SubmittingPatches that I am unable to update; that really needs a thorough redo.

docs: netdev: document guidance on cleanup patches
The purpose of this section is to document what is the current practice regarding clean-up patches which address checkpatch warnings and similar problems. I feel there is a value in having this documented so others can easily refer to it. Clearly this topic is subjective. And to some extent the current practice discourages a wider range of patches than is described here. But I feel it is best to start somewhere, with the most well established part of the current practice.

kbuild: generate offset range data for builtin modules
Create file module.builtin.ranges that can be used to find where
built-in modules are located by their addresses. This will be useful for
tracing tools to find what functions are for various built-in modules.
The offset range data for builtin modules is generated using:
- modules.builtin: associates object files with module names
- vmlinux.map: provides load order of sections and offset of first member
per section
- vmlinux.o.map: provides offset of object file content per section
- .*.cmd: build cmd file with KBUILD_MODFILE
The generated data will look like:
.text 00000000-00000000 = _text
.text 0000baf0-0000cb10 amd_uncore
.text 0009bd10-0009c8e0 iosf_mbi
...
.text 00b9f080-00ba011a intel_skl_int3472_discrete
.text 00ba0120-00ba03c0 intel_skl_int3472_discrete intel_skl_int3472_tps68470
.text 00ba03c0-00ba08d6 intel_skl_int3472_tps68470
...
.data 00000000-00000000 = _sdata
.data 0000f020-0000f680 amd_uncore
For each ELF section, it lists the offset of the first symbol. This can
be used to determine the base address of the section at runtime.
Next, it lists (in strict ascending order) offset ranges in that section
that cover the symbols of one or more builtin modules. Multiple ranges
can apply to a single module, and ranges can be shared between modules.
The CONFIG_BUILTIN_MODULE_RANGES option controls whether offset range data
is generated for kernel modules that are built into the kernel image.
How it works:
1. The modules.builtin file is parsed to obtain a list of built-in
module names and their associated object names (the .ko file that
the module would be in if it were a loadable module, hereafter
referred to as <kmodfile>). This object name can be used to
identify objects in the kernel compile because any C or assembler
code that ends up into a built-in module will have the option
-DKBUILD_MODFILE=<kmodfile> present in its build command, and those
can be found in the .<obj>.cmd file in the kernel build tree.
If an object is part of multiple modules, they will all be listed
in the KBUILD_MODFILE option argument.
This allows us to conclusively determine whether an object in the
kernel build belong to any modules, and which.
2. The vmlinux.map is parsed next to determine the base address of each
top level section so that all addresses into the section can be
turned into offsets. This makes it possible to handle sections
getting loaded at different addresses at system boot.
We also determine an 'anchor' symbol at the beginning of each
section to make it possible to calculate the true base address of
a section at runtime (i.e. symbol address - symbol offset).
We collect start addresses of sections that are included in the top
level section. This is used when vmlinux is linked using vmlinux.o,
because in that case, we need to look at the vmlinux.o linker map to
know what object a symbol is found in.
And finally, we process each symbol that is listed in vmlinux.map
(or vmlinux.o.map) based on the following structure:
vmlinux linked from vmlinux.a:
vmlinux.map:
<top level section>
<included section> -- might be same as top level section)
<object> -- built-in association known
<symbol> -- belongs to module(s) object belongs to
...
vmlinux linked from vmlinux.o:
vmlinux.map:
<top level section>
<included section> -- might be same as top level section)
vmlinux.o -- need to use vmlinux.o.map
<symbol> -- ignored
...
vmlinux.o.map:
<section>
<object> -- built-in association known
<symbol> -- belongs to module(s) object belongs to
...
3. As sections, objects, and symbols are processed, offset ranges are
constructed in a straight-forward way:
- If the symbol belongs to one or more built-in modules:
- If we were working on the same module(s), extend the range
to include this object
- If we were working on another module(s), close that range,
and start the new one
- If the symbol does not belong to any built-in modules:
- If we were working on a module(s) range, close that range

Documentation: embargoed-hardware-issues.rst: add a section documenting the "early access" process
Over the past years there have been many "misunderstandings" and "confusion" as to who is, and is not, allowed early access to the changes created by the members of the embargoed hardware issue teams working on a specific problem. The current process, while it does work, is "difficult" for many companies to understand and agree with. Because of this, there has been numerous attempts by many companies to work around the process by lies, subterfuge, and other side channels sometimes involving unsuspecting lawyers. Cut all of that out, and put the responsibility of distributing code on the silicon vendor affected, as they already have legal agreements in place that cover this type of distribution. When this distribution happens, the developers involved MUST be notified of this happening, to be kept aware of the situation at all times. The wording here has been hashed out by many different companies and lawyers involved in the process, as well as community members and everyone now agrees that the proposed change here should work better than what is currently happening. This change has been approved by a review from a large number of different open source legal members, representing the companies involved in this process.

The embargoed-hardware-issues.rst file needed a bunch of minor grammar, punctuation, and syntax cleanups based on feedback we have gotten over the past few years. The main change here is the term "silicon" being used over "hardware" to differentiate between companies that make a chip (i.e. a CPU) and those that take the chip and put it into their system. No process changes are made here at all, only clarification for the way the current process works. All of these changes have been approved by a review from a large number of different open source legal members, representing the companies involved in this process.

Rust changes for v6.11
The highlight is the establishment of a minimum version for the Rust toolchain, including 'rustc' (and bundled tools) and 'bindgen'. The initial minimum will be the pinned version we currently have, i.e. we are just widening the allowed versions. That covers 3 stable Rust releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow), plus beta, plus nightly. This should already be enough for kernel developers in distributions that provide recent Rust compiler versions routinely, such as Arch Linux, Debian Unstable (outside the freeze period), Fedora Linux, Gentoo Linux (especially the testing channel), Nix (unstable) and openSUSE Slowroll and Tumbleweed. In addition, the kernel is now being built-tested by Rust's pre-merge CI. That is, every change that is attempting to land into the Rust compiler is tested against the kernel, and it is merged only if it passes. Similarly, the bindgen tool has agreed to build the kernel in their CI too. Thus, with the pre-merge CI in place, both projects hope to avoid unintentional changes to Rust that break the kernel. This means that, in general, apart from intentional changes on their side (that we will need to workaround conditionally on our side), the upcoming Rust compiler versions should generally work. In addition, the Rust project has proposed getting the kernel into stable Rust (at least solving the main blockers) as one of its three flagship goals for 2024H2 [1]. I would like to thank Niko, Sid, Emilio et al. for their help promoting the collaboration between Rust and the kernel. [1] https://rust-lang.github.io/rust-project-goals/2024h2/index.html#flagship-goals Toolchain and infrastructure: - Support several Rust toolchain versions. - Support several bindgen versions. - Remove 'cargo' requirement and simplify 'rusttest', thanks to 'alloc' having been dropped last cycle. - Provide proper error reporting for the 'rust-analyzer' target.

Nothing hugely exciting happening in the documentation tree this time
around, mostly more of the usual:
- More Spanish, Italian, and Chinese translations
- A new script, scripts/checktransupdate.py, can be used to see which
commits have touched an (English) document since a given translation was
last updated.
- A couple of "best practices" suggestions (on Link: tags and off-list
discussions) that were not entirely at consensus level, but I concluded
they were close enough to accept.
- Some nice cleanups removing documentation for kernel parameters that have
not been recognized for ... a long time.
...along with the usual updates, typo fixes, and such.

kbuild: raise the minimum GNU Make requirement to 4.0
RHEL/CentOS 7, popular distributions that install GNU Make 3.82, reached EOM/EOL on June 30, 2024. While you may get extended support, it is a good time to raise the minimum GNU Make version. The new requirement, GNU Make 4.0, was released in October, 2013. I did not touch the Makefiles under tools/ because I do not know the requirements for building tools. I do not find any GNU Make version checks under tools/. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nathan Chancellor <nathan@kernel.org> |

docs: rust: quick-start: add section on Linux distributions
Now that we are starting to support several Rust compiler and `bindgen` versions, there is a good chance some Linux distributions work out of the box. Thus, provide some instructions on how to set the toolchain up for a few major Linux distributions. This simplifies the setup users need to build the kernel. In addition, add an introduction to the document so that it is easier to understand its structure and move the LLVM+Rust kernel.org toolchains paragraph there (removing "depending on the Linux version"). We may want to reorganize the document or split it in the future, but I wanted to focus this commit on the new information added about each particular distribution. Finally, remove the `rustup`'s components mention in `changes.rst` since users do not need it if they install the toolchain via the distributions (and anyway it was too detailed for that main document).

rust: start supporting several compiler versions
It is time to start supporting several Rust compiler versions and thus establish a minimum Rust version. We may still want to upgrade the minimum sometimes in the beginning since there may be important features coming into the language that improve how we write code (e.g. field projections), which may or may not make sense to support conditionally. We will start with a window of two stable releases, and widen it over time. Thus this patch does not move the current minimum (1.78.0), but instead adds support for the recently released 1.79.0. This should already be enough for kernel developers in distributions that provide recent Rust compiler versions routinely, such as Arch Linux, Debian Unstable (outside the freeze period), Fedora Linux, Gentoo Linux (especially the testing channel), Nix (unstable) and openSUSE Tumbleweed. See the documentation patch about it later in this series. In addition, Rust for Linux is now being built-tested in Rust's pre-merge CI [1]. That is, every change that is attempting to land into the Rust compiler is tested against the kernel, and it is merged only if it passes -- thanks to the Rust project for that! Thus, with the pre-merge CI in place, both projects hope to avoid unintentional changes to Rust that break the kernel. This means that, in general, apart from intentional changes on their side (that we will need to workaround conditionally on our side), the upcoming Rust compiler versions should generally work. For instance, currently, the beta (1.80.0) and nightly (1.81.0) branches work as well. Of course, the Rust for Linux CI job in the Rust toolchain may still need to be temporarily disabled for different reasons, but the intention is to help bring Rust for Linux into stable Rust.

docs: handling-regressions.rst: recommend using "Closes:" tags
Update the handling-regressions guide to recommend using "Closes:" tags rather than "Link:" when referencing fixed reports. The latter was used originally but now is only recommended when the given patch only fixes part of the issue, as described in submitting-patches. Briefly mention that and also note that regzbot currently doesn't make a distinction. Also fix a typo.

A function-like macro could result in build warnings such as "unused

docs: stable-kernel-rules: create special tag to flag 'no backporting'
Document a new variant of the stable tag developers can use to make the stable team's tools ignore a change[1]. That way developers can use 'Fixes:' tags without fearing the changes might be backported in semi-automatic fashion. Such concerns are the reason why some developers deliberately omit the 'Fixes:' tag in changes[2] -- which somewhat undermines the reason for the existence of that tag and might be unwise in the long term[3].

arm64: boot: Support Flat Image Tree
Add a script which produces a Flat Image Tree (FIT), a single file containing the built kernel and associated devicetree files. Compression defaults to gzip which gives a good balance of size and performance. The files compress from about 86MB to 24MB using this approach. The FIT can be used by bootloaders which support it, such as U-Boot and Linuxboot. It permits automatic selection of the correct devicetree, matching the compatible string of the running board with the closest compatible string in the FIT. There is no need for filenames or other workarounds. Add a 'make image.fit' build target for arm64, as well. The FIT can be examined using 'dumpimage -l'. This uses the 'dtbs-list' file but processes only .dtb files, ignoring the overlay .dtbo files. This features requires pylibfdt (use 'pip install libfdt'). It also requires compression utilities for the algorithm being used. Supported compression options are the same as the Image.xxx files. Use FIT_COMPRESSION to select an algorithm other than gzip. While FIT supports a ramdisk / initrd, no attempt is made to support this here, since it must be built separately from the Linux build.

Use colon as command terminator everywhere for consistency, even though it's not strictly necessary. That way it will also match regzbot's reference documentation.

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: submit-checklist: structure by category
While going through the submit checklist, the list order seemed rather random, probably just by historical coincidences of always adding yet the next point someone thought of at the end of the list. Structure and order them by the category of such activity, reviewing, documenting, checking with tools, building and testing. As the diff of the reordering is large: Review code now includes previous points 1, 5 and 22. Review Kconfig includes previous 6, 7 and 8. Documenting includes previous 11, 15, 16, 17, 18 and 23. Checking with tools includes previous 5, 9 and 10. Building includes previous 2, 3, 20 and 24. Testing includes previous 12, 13, 14, 19 and 21. Previous point 4 (compile for ppc64) was merged into point 3 (build for many architectures), as it was just a further note to cross-compiling. Previous point 5 was split into one in review and one in checking to have every previous point in the right category. Point 11 was shortened, as building documentation is mentioned already in Build your code, 1d. A note that was presented visually much too aggressive in the HTML view was turned into a simple "Note that..." sentence in the enumeration. The recommendation to test with the -mm patchset (previous 21, now testing, point 5) was updated to the current state of affairs to test with a recent tag of linux-next. Note that the previous first point still remains the first list even after reordering. Randy confirmed that it was important to Stephen Rothwell to keep 'include what you use' to be the first in the list. While at it, replace the reference to the obsolete CONFIG_DEBUG_SLAB with CONFIG_SLUB_DEBUG.

kbuild: raise the minimum supported version of LLVM to 13.0.1
Patch series "Bump the minimum supported version of LLVM to 13.0.1".
This series bumps the minimum supported version of LLVM for building the
kernel to 13.0.1. The first patch does the bump and all subsequent
patches clean up all the various workarounds and checks for earlier
versions.
Quoting the first patch's commit message for those that were only on CC
for the clean ups:
When __builtin_mul_overflow() has arguments that differ in terms of
signedness and width, LLVM may generate a libcall to __muloti4 because
it performs the checks in terms of 65-bit multiplication. This issue
becomes harder to hit (but still possible) after LLVM 12.0.0, which
includes a special case for matching widths but different signs.
To gain access to this special case, which the kernel can take advantage
of when calls to __muloti4 appear, bump the minimum supported version of
LLVM for building the kernel to 13.0.1. 13.0.1 was chosen because there
is minimal impact to distribution support while allowing a few more
workarounds to be dropped in the kernel source than if 12.0.0 were
chosen. Looking at container images of up to date distribution versions:
archlinux:latest clang version 16.0.6

ubuntu:latest Ubuntu clang version 14.0.0-1ubuntu1.1
ubuntu:rolling Ubuntu clang version 16.0.6 (15)
ubuntu:devel Ubuntu clang version 17.0.6 (3)
The only distribution that gets left behind is Debian Bullseye, as the
default version is 11.0.1; other distributions either have a newer
version than 13.0.1 or one older than the current minimum of 11.0.0.
Debian has easy access to more recent LLVM versions through
apt.llvm.org, so this is not as much of a concern. There are also the
kernel.org LLVM toolchains, which should work with distributions with
glibc 2.28 and newer.
Another benefit of slimming up the number of supported versions of LLVM
for building the kernel is reducing the build capacity needed to support
a matrix that builds with each supported version, which allows a matrix
to reallocate the freed up build capacity towards something else, such
as more configuration combinations.
This passes my build matrix with all supported versions.
This is based on Andrew's mm-nonmm-unstable to avoid trivial conflicts
with my series to update the LLVM links across the repository [1] but I
can easily rebase it to linux-kbuild if Masahiro would rather these
patches go through there (and defer the conflict resolution to the merge
window).

easy access to more recent LLVM versions through apt.llvm.org, so this is
not as much of a concern. There are also the kernel.org LLVM toolchains,
which should work with distributions with glibc 2.28 and newer.
Another benefit of slimming up the number of supported versions of LLVM
for building the kernel is reducing the build capacity needed to support a
matrix that builds with each supported version, which allows a matrix to
reallocate the freed up build capacity towards something else, such as
more configuration combinations.

- Some reworking of the Documentation/process front page to, hopefully,

- Various kernel-doc tweaks to, for example, make it deal properly with
__counted_by annotations.
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained
effort by Randy, Vegard, and myself has addressed almost all of those,
bringing the documentation back into sync with the code. The fixes are

Docs: remove mentions of fdformat from util-linux
Since util-linux commit 13b26e3c36d1
("fdformat: remove command from default build")
the fdformat tool is not built anymore by default.
As a result it is not packaged anymore by distributions and therefore
not usable by users.
Instead mention the "mount" command as more likely to be present
alternative.
Also drop the reference to fdformat from the list of features of new
versions of util-linux.

Add .editorconfig file for basic formatting
EditorConfig is a specification to define the most basic code formatting
stuff, and it's supported by many editors and IDEs, either directly or
via plugins, including VSCode/VSCodium, Vim, emacs and more.
It allows to define formatting style related to indentation, charset,
end of lines and trailing whitespaces. It also allows to apply different
formats for different files based on wildcards, so for example it is
possible to apply different configs to *.{c,h}, *.py and *.rs.
In linux project, defining a .editorconfig might help to those people
that work on different projects with different indentation styles, so
they cannot define a global style. Now they will directly see the
correct indentation on every fresh clone of the project.
See https://editorconfig.org

There has been more than a few threads which went idle before the merge window and now people came back to them and started asking about next steps. We currently tell people to be patient and not to repost too often. Our "not too often", however, is still a few orders of magnitude faster than other subsystems. Or so I feel after hearing people talk about review rates at LPC. Clarify in the doc that if the discussion went idle for a week on netdev, 95% of the time there's no point waiting longer.

The number of commits for documentation is not huge this time around, but
there are some significant changes nonetheless:
- Some more Spanish-language and Chinese translations.
- The much-discussed documentation of the confidential-computing threat
model.
- Powerpc and RISCV documentation move under Documentation/arch - these
complete this particular bit of documentation churn.
- A large traditional-Chinese documentation update.
- A new document on backporting and conflict resolution.
- Some kernel-doc and Sphinx fixes.
Plus the usual smattering of smaller updates and typo fixes.

Networking changes for 6.7.
Core & protocols
----------------
- Support usec resolution of TCP timestamps, enabled selectively by
a route attribute.
- Defer regular TCP ACK while processing socket backlog, try to send
a cumulative ACK at the end. Increase single TCP flow performance
on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).
- The Fair Queuing (FQ) packet scheduler:
- add built-in 3 band prio / WRR scheduling
- support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
- improve inactive flow reporting
- optimize the layout of structures for better cache locality
- Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
replacement for the old MD5 option.
- Add more retransmission timeout (RTO) related statistics to TCP_INFO.
- Support sending fragmented skbs over vsock sockets.
- Make sure we send SIGPIPE for vsock sockets if socket was shutdown().
- Add sysctl for ignoring lower limit on lifetime in Router
Advertisement PIO, based on an in-progress IETF draft.
- Add sysctl to control activation of TCP ping-pong mode.
- Add sysctl to make connection timeout in MPTCP configurable.
- Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
limit the number of wakeups.
- Support netlink GET for MDB (multicast forwarding), allowing user
space to request a single MDB entry instead of dumping the entire
table.
- Support selective FDB flushing in the VXLAN tunnel driver.
- Allow limiting learned FDB entries in bridges, prevent OOM attacks.
- Allow controlling via configfs netconsole targets which were created
via the kernel cmdline at boot, rather than via configfs at runtime.
- Support multiple PTP timestamp event queue readers with different
filters.
- MCTP over I3C.
BPF
---
- Add new veth-like netdevice where BPF program defines the logic
of the xmit routine. It can operate in L3 and L2 mode.
- Support exceptions - allow asserting conditions which should
never be true but are hard for the verifier to infer.
With some extra flexibility around handling of the exit / failure.
https://lwn.net/Articles/938435/
- Add support for local per-cpu kptr, allow allocating and storing
per-cpu objects in maps. Access to those objects operates on
the value for the current CPU. This allows to deprecate local
one-off implementations of per-CPU storage like
BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.
- Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
for systemd to re-implement the LogNamespace feature which allows
running multiple instances of systemd-journald to process the logs
of different services.
- Enable open-coded task_vma iteration, after maple tree conversion
made it hard to directly walk VMAs in tracing programs.
- Add open-coded task, css_task and css iterator support.
One of the use cases is customizable OOM victim selection via BPF.
- Allow source address selection with bpf_*_fib_lookup().
- Add ability to pin BPF timer to the current CPU.
- Prevent creation of infinite loops by combining tail calls and
fentry/fexit programs.
- Add missed stats for kprobes to retrieve the number of missed kprobe
executions and subsequent executions of BPF programs.
- Inherit system settings for CPU security mitigations.
- Add BPF v4 CPU instruction support for arm32 and s390x.
Changes to common code
----------------------
- overflow: add DEFINE_FLEX() for on-stack definition of structs
with flexible array members.
- Process doc update with more guidance for reviewers.
Driver API
----------
- Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
mutex in most places and remove a lot of smaller locks.
- Create a common DPLL configuration API. Allow configuring
and querying state of PLL circuits used for clock syntonization,
in network time distribution.
- Unify fragmented and full page allocation APIs in page pool code.
Let drivers be ignorant of PAGE_SIZE.
- Rework PHY state machine to avoid races with calls to phy_stop().
- Notify DSA drivers of MAC address changes on user ports, improve
correctness of offloads which depend on matching port MAC addresses.
- Allow antenna control on injected WiFi frames.
- Reduce the number of variants of napi_schedule().
- Simplify error handling when composing devlink health messages.
Misc
----
- A lot of KCSAN data race "fixes", from Eric.
- A lot of __counted_by() annotations, from Kees.
- A lot of strncpy -> strscpy and printf format fixes.
- Replace master/slave terminology with conduit/user in DSA drivers.
- Handful of KUnit tests for netdev and WiFi core.

Rust changes for v6.7
A small one compared to the previous one in terms of features. In terms
of lines, as usual, the 'alloc' version upgrade accounts for most of them.
Toolchain and infrastructure:
- Upgrade to Rust 1.73.0.
This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. They contain the fixes for
a few issues we reported to the Rust project.
In addition, a few cleanups indicated by the upgraded compiler
or possible thanks to it. For instance, the compiler now detects
redundant explicit links.
- A couple changes to the Rust 'Makefile' so that it can be used with
toybox tools, allowing Rust to be used in the Android kernel build.
x86:
- Enable IBT if enabled in C.
Documentation:
- Add "The Rust experiment" section to the Rust index page.
MAINTAINERS
- Add Maintainer Entry Profile field ('P:').
- Update our 'W:' field to point to the webpage we have been building
this year.

docs: submitting-patches: encourage direct notifications to commenters
Commenters may not receive new versions of patches via the lists. Without a directed notification to them they might miss those new versions. This is frustrating for the patch developers as they don't receive their earned Reviewed-by. It is also frustrating for the commenters, as they might think their review got ignored or they have to dig up new versions from the archive manually. So encourage patch submitters to make sure that all commenters get notified also when no Reviewed-by was issued yet.

docs: add backporting and conflict resolution document
This is a new document based on my 2022 blog post: https://blogs.oracle.com/linux/post/backporting-patches-using-git Although this is aimed at stable contributors and distro maintainers, it does also contain useful tips and tricks for anybody who needs to resolve merge conflicts. By adding this to the kernel as documentation we can more easily point to it e.g. from stable emails about failed backports, as well as allow the community to modify it over time if necessary. I've added this under process/ since it also has process/applying-patches.rst. Another interesting document is maintainer/rebasing-and-merging.rst which maybe should eventually refer to this one, but I'm leaving that as a future cleanup. Thanks to Harshit Mogalapalli for helping with the original blog post as well as this updated document and Bagas Sanjaya for providing thoughtful feedback. v2: fixed heading style, link style, placeholder style, other comments Link: https://lore.kernel.org/linux-doc/20230303162553.17212-1-vegard.nossum@oracle.com/ Cc: Harshit Mogalapalli <harshit.m.mogalapalli@oracle.com> Cc: Bagas Sanjaya <bagasdotme@gmail.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Cc: "Jason A.

Documentation work keeps chugging along; stuff for 6.6 includes:
- Work from Carlos Bilbao to integrate rustdoc output into the generated
HTML documentation. This took some work to figure out how to do it
without slowing the docs build and without creating people who don't have
Rust installed, but Carlos got there.
- Move the loongarch and mips architecture documentation under
Documentation/arch/.
- Some more maintainer documentation from Jakub
...plus the usual assortment of updates, translations, and fixes.

Networking changes for 6.6.
Core
----
- Increase size limits for to-be-sent skb frag allocations. This
allows tun, tap devices and packet sockets to better cope with large
writes operations.
- Store netdevs in an xarray, to simplify iterating over netdevs.
- Refactor nexthop selection for multipath routes.
- Improve sched class lifetime handling.
- Add backup nexthop ID support for bridge.
- Implement drop reasons support in openvswitch.
- Several data races annotations and fixes.
- Constify the sk parameter of routing functions.
- Prepend kernel version to netconsole message.
Protocols
---------
- Implement support for TCP probing the peer being under memory
pressure.
- Remove hard coded limitation on IPv6 specific info placement
inside the socket struct.
- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
per socket scaling factor.
- Scaling-up the IPv6 expired route GC via a separated list of
expiring routes.
- In-kernel support for the TLS alert protocol.
- Better support for UDP reuseport with connected sockets.
- Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
header size.
- Get rid of additional ancillary per MPTCP connection struct socket.
- Implement support for BPF-based MPTCP packet schedulers.
- Format MPTCP subtests selftests results in TAP.
- Several new SMC 2.1 features including unique experimental options,
max connections per lgr negotiation, max links per lgr negotiation.
BPF
---
- Multi-buffer support in AF_XDP.
- Add multi uprobe BPF links for attaching multiple uprobes
and usdt probes, which is significantly faster and saves extra fds.
- Implement an fd-based tc BPF attach API (TCX) and BPF link support on
top of it.
- Add SO_REUSEPORT support for TC bpf_sk_assign.
- Support new instructions from cpu v4 to simplify the generated code and
feature completeness, for x86, arm64, riscv64.
- Support defragmenting IPv(4|6) packets in BPF.
- Teach verifier actual bounds of bpf_get_smp_processor_id()
and fix perf+libbpf issue related to custom section handling.
- Introduce bpf map element count and enable it for all program types.
- Add a BPF hook in sys_socket() to change the protocol ID
from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
- Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
- Add uprobe support for the bpf_get_func_ip helper.
- Check skb ownership against full socket.
- Support for up to 12 arguments in BPF trampoline.
- Extend link_info for kprobe_multi and perf_event links.
Netfilter
---------
- Speed-up process exit by aborting ruleset validation if a
fatal signal is pending.
- Allow NLA_POLICY_MASK to be used with BE16/BE32 types.
Driver API
----------
- Page pool optimizations, to improve data locality and cache usage.
- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
for raw ioctl() handling in drivers.
- Simplify genetlink dump operations (doit/dumpit) providing them
the common information already populated in struct genl_info.
- Extend and use the yaml devlink specs to [re]generate the split ops.
- Introduce devlink selective dumps, to allow SF filtering SF based on
handle and other attributes.
- Add yaml netlink spec for netlink-raw families, allow route, link and
address related queries via the ynl tool.
- Remove phylink legacy mode support.
- Support offload LED blinking to phy.
- Add devlink port function attributes for IPsec.

rust: bindgen: upgrade to 0.65.1
In LLVM 16, anonymous items may return names like `(unnamed union at ..)`
rather than empty names [1], which breaks Rust-enabled builds because
bindgen assumed an empty name instead of detecting them via
`clang_Cursor_isAnonymous` [2]:
$ make rustdoc LLVM=1 CLIPPY=1 -j$(nproc)
RUSTC L rust/core.o
BINDGEN rust/bindings/bindings_generated.rs
BINDGEN rust/bindings/bindings_helpers_generated.rs
BINDGEN rust/uapi/uapi_generated.rs
thread 'main' panicked at '"ftrace_branch_data_union_(anonymous_at__/_/include/linux/compiler_types_h_146_2)" is not a valid Ident', .../proc-macro2-1.0.24/src/fallback.rs:693:9
...
thread 'main' panicked at '"ftrace_branch_data_union_(anonymous_at__/_/include/linux/compiler_types_h_146_2)" is not a valid Ident', .../proc-macro2-1.0.24/src/fallback.rs:693:9
...
This was fixed in bindgen 0.62.0. Therefore, upgrade bindgen to
a more recent version, 0.65.1, to support LLVM 16.
Since bindgen 0.58.0 changed the `--{white,black}list-*` flags to
`--{allow,block}list-*` [3], update them on our side too.
In addition, bindgen 0.61.0 moved its CLI utility into a binary crate
called `bindgen-cli` [4]. Thus update the installation command in the
Quick Start guide.
Moreover, bindgen 0.61.0 changed the default functionality to bind
`size_t` to `usize` [5] and added the `--no-size_t-is-usize` flag
to not bind `size_t` as `usize`. Then bindgen 0.65.0 removed
the `--size_t-is-usize` flag [6]. Thus stop passing the flag to bindgen.
Finally, bindgen 0.61.0 added support for the `noreturn` attribute (in
its different forms) [7]. Thus remove the infinite loop in our Rust
panic handler after calling `BUG()`, since bindgen now correctly
generates a `BUG()` binding that returns `!` instead of `()`.

Documentation/process: maintainer-soc: add clean platforms profile
Some SoC platforms require that commits must not bring any new dtbs_check warnings. Maintainers of such platforms usually have some automation set, so any new warning will be spotted sooner or later.

docs: stable-kernel-rules: move text around to improve flow
Move the short description about when to use which of the submission options to the top of the section, as it currently sits somewhat odd in the middle between option 3 and examples of option 1. Also move the examples of Option 1 into the section describing it (which in the diff looks like option 2 and 3 are moving down). No text changes, just moving it around.

docs: stable-kernel-rules: make rule section more straight forward
Tweak some of the rule text to make things more straight forward, with the goal to stick closely to the intend of the old text: * put the "it or equivalent fix must be upstream" rule at the top, as it's one of the most important ones that at the same time often seems to be missed by developers. * "It must fix only one thing" was dropped, as that is almost always a thing that needs to be handled earlier when the change is mainlined. Furthermore, this is already indirectly covered by the "Separate your changes" section in Documentation/process/submitting-patches.rst which the rules already point to. * six other rules are in the end one rule with clarifications; structure the text accordingly to make it a lot easier to follow and understand the intend. * drop the 'In short, something critical' from one of those notes: it contradicts the "real bug that bothers people" aspect somewhat and does not really add anything CC: Greg KH <gregkh@linuxfoundation.org> CC: Sasha Levin <sashal@kernel.org> CC: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Thorsten Leemhuis <linux@leemhuis.info> Link: https://lore.kernel.org/r/f83e812879caa978a51a1a7cae7c359f29fc093c.1689056247.git.linux@leemhuis.info Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

ARM64:
* Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage splitting in the stage-2
fault path.
* Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
services that live in the Secure world. pKVM intervenes on FF-A calls
to guarantee the host doesn't misuse memory donated to the hyp or a
pKVM guest.
* Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
* Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set configuration
from userspace, but the intent is to relax this limitation and allow
userspace to select a feature set consistent with the CPU.
* Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
* Use a separate set of pointer authentication keys for the hypervisor
when running in protected mode, as the host is untrusted at runtime.
* Ensure timer IRQs are consistently released in the init failure
paths.
* Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
(FEAT_EVT), as it is a register commonly read from userspace.
* Erratum workaround for the upcoming AmpereOne part, which has broken
hardware A/D state management.
RISC-V:
* Redirect AMO load/store misaligned traps to KVM guest
* Trap-n-emulate AIA in-kernel irqchip for KVM guest
* Svnapot support for KVM Guest
s390:
* New uvdevice secret API
* CMM selftest and fixes
* fix racy access to target CPU for diag 9c
x86:
* Fix missing/incorrect #GP checks on ENCLS
* Use standard mmu_notifier hooks for handling APIC access page
* Drop now unnecessary TR/TSS load after VM-Exit on AMD
* Print more descriptive information about the status of SEV and SEV-ES during
module load
* Add a test for splitting and reconstituting hugepages during and after
dirty logging
* Add support for CPU pinning in demand paging test
* Add support for AMD PerfMonV2, with a variety of cleanups and minor fixes
included along the way

Pull kvm updates from Paolo Bonzini:
"ARM64:
- Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage splitting in the
stage-2 fault path.
- Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact
with services that live in the Secure world. pKVM intervenes on
FF-A calls to guarantee the host doesn't misuse memory donated to
the hyp or a pKVM guest.
- Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
- Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set
configuration from userspace, but the intent is to relax this
limitation and allow userspace to select a feature set consistent
with the CPU.
- Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
- Use a separate set of pointer authentication keys for the
hypervisor when running in protected mode, as the host is untrusted
at runtime.
- Ensure timer IRQs are consistently released in the init failure
paths.
- Avoid trapping CTR_EL0 on systems with Enhanced Virtualization
Traps (FEAT_EVT), as it is a register commonly read from userspace.
- Erratum workaround for the upcoming AmpereOne part, which has
broken hardware A/D state management.
RISC-V:
- Redirect AMO load/store misaligned traps to KVM guest
- Trap-n-emulate AIA in-kernel irqchip for KVM guest
- Svnapot support for KVM Guest
s390:
- New uvdevice secret API
- CMM selftest and fixes
- fix racy access to target CPU for diag 9c
x86:
- Fix missing/incorrect #GP checks on ENCLS
- Use standard mmu_notifier hooks for handling APIC access page
- Drop now unnecessary TR/TSS load after VM-Exit on AMD
- Print more descriptive information about the status of SEV and
SEV-ES during module load
- Add a test for splitting and reconstituting hugepages during and
after dirty logging
- Add support for CPU pinning in demand paging test
- Add support for AMD PerfMonV2, with a variety of cleanups and minor
fixes included along the way
- Add a "nx_huge_pages=never" option to effectively avoid creating NX
hugepage recovery threads (because nx_huge_pages=off can be toggled
at runtime)
- Move handling of PAT out of MTRR code and dedup SVM+VMX code
- Fix output of PIC poll command emulation when there's an interrupt

docs: remove the tips on how to submit patches from MAINTAINERS
Having "how to submit patches" in MAINTAINTERS seems out of place. We have a whole section of documentation about it, duplication is harmful and a lot of the text looks really out of date. Sections 1, 2 and 4 look really, really old and not applicable to the modern process. Section 3 is obvious but also we have build bots now. Section 5 is a bit outdated (diff -u?!). But I like the part about factoring out shared code, so add that to process docs. Section 6 is unnecessary? Section 7 is covered by more appropriate docs.

ARM: New SoC support for 6.5
There are two new SoC families this time, and both appear fairly similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are both dual-core Cortex-A35 based chips for the low-power industrial embedded market, and they mark the first 64-bit product in a widely used family of 32-bit Arm MCUs and SoCs. The way into the kernel is completely different here: The team at ST has a long history of working upstream with their STM32MP1 and other SoCs, and they produced a complete port to arm64 together with the initial announcement. Nuvoton also has multiple SoC product lines with current or previous upstream support, but those are maintained by third parties and are unrelated. The patch series from Nuvoton's Jacky Huang had to go through many revisisions to get to this point and is still missing a few drivers including the serial port for the moment. The branch contains the devicetree files as well as all the code changes, in order to have something that can be tested standalone. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmScqtkACgkQYKtH/8kJ Uifqyg//XgvZBxb/2GILYcThVgLoo1fYA9tG5M0LERY/aPiUwrCwIl5swGQXK4vK E3UBLsQURer4yEBRq7iB6RGbwa4Opjdy3yTkj6WSgEMPh6e6jGvmm+dJ7HuWeviS 8oeyo3Xar6tIF+A8xlBloHA4J6690FYB40McQzh8sWG5SE+id56S71NGnNW0kQTn wsul9BZcGVoyMYNBi/uXtOVUPy7jF3UBC3HJF9UOT7q77bCLjVc/aHmmnZ3zmbYA 2oX3X5hVJakFba6vnz+rjNlzuAoGXJPDdsKFxBysdsksac/TxqRIQGNe75DZZVgz ESTpt1QqjmCFw32HEzi8Ne22FOpzlBqUxBMznHPenpz1/om2ezs3q7ffuPqKvMaq PANuK++JKJaBChVMzJbn84Sr1fvO4ecGJpKZTFC6t6SqHQNQFJT6rfMHx01Xw2wW LjKfEBCR6zEXN0+FaaujgJ4y/9pH1VHPynrZJG9WEwPUEZb2kJ/2RMXjNpzOWKiB pWYV1oW2TqFKYKhFm/pjkbi6Rq76UwEi8fWWoGMkmeV3KZ/0GFauQhItu6mX3s7W uGnUQyrBzWzUoashYFuNtXKHYdwuWgOmG660BXHkyxwvqV96ICGEJ+97zGIBDj81 F8zLxEjPbsEZqGGSosAyk9oYC6eh7eK2V7xx+CUYLTuKZw13zNo= =zaVi -----END PGP SIGNATURE----- Merge tag 'soc-newsoc-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull new ARM SoC support from Arnd Bergmann: "There are two new SoC families this time, and both appear fairly similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are both dual-core Cortex-A35 based chips for the low-power industrial embedded market, and they mark the first 64-bit product in a widely used family of 32-bit Arm MCUs and SoCs.

docs: handling-regressions: rework section about fixing procedures
This basically rewrites the 'Prioritize work on fixing regressions' section of Documentation/process/handling-regressions.rst for various reasons. Among them: some things were too demanding, some didn't align well with the usual workflows, and some apparently were not clear enough -- and of course a few things were missing that would be good to have in there. Linus for example recently stated that regressions introduced during the past year should be handled similarly to regressions from the current cycle, if it's a clear fix with no semantic subtlety. His exact wording[1] didn't fit well into the text structure, but the author tried to stick close to the apparent intention. It was a noble goal from the original author to state "[prevent situations that might force users to] continue running an outdated and thus potentially insecure kernel version for more than two weeks after a regression's culprit was identified"; this directly led to the goal "fix regression in mainline within one week, if the issue made it into a stable/longterm kernel", because the stable team needs time to pick up and prepare a new release. But apparently all that was a bit too demanding. That "one week" target for example doesn't align well with the usual habits of the subsystem maintainers, which normally send their fixes to Linus once a week; and it doesn't align too well with stable/longterm releases either, which often enter a -rc phase on Mondays or Tuesdays and then are released two to three days later. And asking developers to create, review, and mainline fixes within one week might be too much to ask for in general. Hence tone the general goal down to three weeks and use an approach that better aligns with the usual merging and release habits. While at it, also make the rules of thumb a bit easier to follow by grouping them by topic (e.g. generic things, timing, procedures, ...). Also add text for a few cases where recent discussions showed they need covering. Among them are multiple points that better explain the relations to stable and longterm kernels and the team that manages them; they and the group seperators are the primary reason why this whole section sadly grew somewhat in the rewrite. The group about those relations led to one addition the author came up with without any precedent from Linus: the text now tells developers to add a stable tag for any regression that made it into a proper mainline release during the past 12 months. This is meant to ensure the stable team will definitely notice any fixes for recent regressions. That includes those introduced shortly before a new mainline release and found right after it; without such a rule the stable team might miss the fix, which then would only reach users after weeks or months with later releases. Note, the aspect "Do not consider regressions from the current cycle as something that can wait till the cycle's end [...]" might look like an addition, but was kinda was in the old text as well -- but only indirectly. That apparently was too subtle, as many developers seem to assume waiting till the end of the cycle is fine (even for build fixes). In practice this was especially problematic when a cause of a regression made it into a proper release (either directly or through a backport). A revert performed by Linus shortly before the 6.3 release illustrated that[2], as the developer of the culprit had been willing to revert the culprit about three weeks earlier already -- but didn't do so when a fix came into sight and a maintainer suggested it can wait. Due to that the issue in the end plagued users of 6.2.y at least two weeks longer than necessary, as the fix in the end didn't become ready in time. This issue in fact could have been resolved one or two additional weeks earlier, if the developer had reverted the culprit shortly after it had been identified (which even the old version of the text suggest to do in such cases).

rust: upgrade to Rust 1.68.2
This is the first upgrade to the Rust toolchain since the initial Rust
merge, from 1.62.0 to 1.68.2 (i.e. the latest).
# Context
The kernel currently supports only a single Rust version [1] (rather
than a minimum) given our usage of some "unstable" Rust features [2]
which do not promise backwards compatibility.
The goal is to reach a point where we can declare a minimum version for
the toolchain. For instance, by waiting for some of the features to be
stabilized. Therefore, the first minimum Rust version that the kernel
will support is "in the future".
# Upgrade policy
Given we will eventually need to reach that minimum version, it would be
ideal to upgrade the compiler from time to time to be as close as
possible to that goal and find any issues sooner. In the extreme, we
could upgrade as soon as a new Rust release is out. Of course, upgrading
so often is in stark contrast to what one normally would need for GCC
and LLVM, especially given the release schedule: 6 weeks for Rust vs.
half a year for LLVM and a year for GCC.
Having said that, there is no particular advantage to updating slowly
either: kernel developers in "stable" distributions are unlikely to be
able to use their distribution-provided Rust toolchain for the kernel
anyway [3]. Instead, by routinely upgrading to the latest instead,
kernel developers using Linux distributions that track the latest Rust
release may be able to use those rather than Rust-provided ones,
especially if their package manager allows to pin / hold back /
downgrade the version for some days during windows where the version may
not match. For instance, Arch, Fedora, Gentoo and openSUSE all provide
and track the latest version of Rust as they get released every 6 weeks.
Then, when the minimum version is reached, we will stop upgrading and
decide how wide the window of support will be. For instance, a year of
Rust versions. We will probably want to start small, and then widen it
over time, just like the kernel did originally for LLVM, see commit

Networking changes for 6.4.
Core
----
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances.
- Reduce compound page head access for zero-copy data transfers.
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
- Threaded NAPI improvements, adding defer skb free support and unneeded
softirq avoidance.
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking.
- Add lockless accesses annotation to sk_err[_soft].
- Optimize again the skb struct layout.
- Extends the skb drop reasons to make it usable by multiple
subsystems.
- Better const qualifier awareness for socket casts.
BPF
---
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and variable-sized
accesses.
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward.
- Add more precise memory usage reporting for all BPF map types.
- Adds support for using {FOU,GUE} encap with an ipip device operating
in collect_md mode and add a set of BPF kfuncs for controlling encap
params.
- Allow BPF programs to detect at load time whether a particular kfunc
exists or not, and also add support for this in light skeleton.
- Bigger batch of BPF verifier improvements to prepare for upcoming BPF
open-coded iterators allowing for less restrictive looping capabilities.
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
programs to NULL-check before passing such pointers into kfunc.
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
local storage maps.
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps.
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree.
- Add BPF verifier support for ST instructions in convert_ctx_access()
which will help new -mcpu=v4 clang flag to start emitting them.
- Add ARM32 USDT support to libbpf.
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations.
Protocols
---------
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address.
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
- Add the handshake upcall mechanism, allowing the user-space
to implement generic TLS handshake on kernel's behalf.
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures.
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers.
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction.
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore.
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter
---------
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged.
- Update bridge netfilter and ovs conntrack helpers to handle
IPv6 Jumbo packets properly, i.e. fetch the packet length
from hop-by-hop extension header. This is needed for BIT TCP
support.
- The iptables 32bit compat interface isn't compiled in by default
anymore.
- Move ip(6)tables builtin icmp matches to the udptcp one.
This has the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used.
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device.
Driver API
----------
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time.
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them.
- Allow the page_pool to directly recycle the pages from safely
localized NAPI.
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization.
- Add YNL support for user headers and struct attrs.
- Add partial YNL specification for devlink.
- Add partial YNL specification for ethtool.
- Add tc-mqprio and tc-taprio support for preemptible traffic classes.
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device.
- Add basic LED support for switch/phy.
- Add NAPI documentation, stop relaying on external links.
- Convert dsa_master_ioctl() to netdev notifier. This is a preparatory
work to make the hardware timestamping layer selectable by user
space.
- Add transceiver support and improve the error messages for CAN-FD
controllers.

Merge tag 'net-next-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"Core:
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances
- Reduce compound page head access for zero-copy data transfers
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
possible
- Threaded NAPI improvements, adding defer skb free support and
unneeded softirq avoidance
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking
- Add lockless accesses annotation to sk_err[_soft]
- Optimize again the skb struct layout
- Extends the skb drop reasons to make it usable by multiple
subsystems
- Better const qualifier awareness for socket casts
BPF:
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and
variable-sized accesses
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward
- Add more precise memory usage reporting for all BPF map types
- Adds support for using {FOU,GUE} encap with an ipip device
operating in collect_md mode and add a set of BPF kfuncs for
controlling encap params
- Allow BPF programs to detect at load time whether a particular
kfunc exists or not, and also add support for this in light
skeleton
- Bigger batch of BPF verifier improvements to prepare for upcoming
BPF open-coded iterators allowing for less restrictive looping
capabilities
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce
BPF programs to NULL-check before passing such pointers into kfunc
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
in local storage maps
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree
- Add BPF verifier support for ST instructions in
convert_ctx_access() which will help new -mcpu=v4 clang flag to
start emitting them
- Add ARM32 USDT support to libbpf
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations
Protocols:
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition
- Add the handshake upcall mechanism, allowing the user-space to
implement generic TLS handshake on kernel's behalf
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter:
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged
- Update bridge netfilter and ovs conntrack helpers to handle IPv6
Jumbo packets properly, i.e. fetch the packet length from
hop-by-hop extension header. This is needed for BIT TCP support
- The iptables 32bit compat interface isn't compiled in by default
anymore
- Move ip(6)tables builtin icmp matches to the udptcp one. This has
the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device
Driver API:
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them
- Allow the page_pool to directly recycle the pages from safely
localized NAPI
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization
- Add YNL support for user headers and struct attrs
- Add partial YNL specification for devlink
- Add partial YNL specification for ethtool
- Add tc-mqprio and tc-taprio support for preemptible traffic classes
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device
- Add basic LED support for switch/phy
- Add NAPI documentation, stop relaying on external links
- Convert dsa_master_ioctl() to netdev notifier. This is a
preparatory work to make the hardware timestamping layer selectable
by user space
- Add transceiver support and improve the error messages for CAN-FD
controllers

Commit volume in documentation is relatively low this time, but there is
still a fair amount going on, including:
- Reorganizing the architecture-specific documentation under
Documentation/arch. This makes the structure match the source directory
and helps to clean up the mess that is the top-level Documentation
directory a bit. This work creates the new directory and moves x86 and
most of the less-active architectures there. The current plan is to move
the rest of the architectures in 6.5, with the patches going through the
appropriate subsystem trees.
- Some more Spanish translations and maintenance of the Italian
translation.
- A new "Kernel contribution maturity model" document from Ted.
- A new tutorial on quickly building a trimmed kernel from Thorsten.
Plus the usual set of updates and fixes.

Documentation/process: always CC responsible lists
The "Select the recipients for your patch" part about CC-ing mailing lists is a bit vague and might be understood that only some lists should be Cc-ed. That's not what most of the maintainers expect. For given code, associated mailing list must always be CC-ed, because the list is used for reviewing and testing patches. Example are the Devicetree bindings patches, which are tested iff Devicetree mailing list is CC-ed.

docs: process: allow Closes tags with links
Since v6.3, checkpatch.pl now complains about the use of "Closes:" tags
followed by a link [1]. It also complains if a "Reported-by:" tag is
followed by a "Closes:" one [2].
As detailed in the first patch, this "Closes:" tag is used for a bit of
time, mainly by DRM and MPTCP subsystems. It is used by some bug trackers
to automate the closure of issues when a patch is accepted. It is even
planned to use this tag with bugzilla.kernel.org [3].
The first patch updates the documentation to explain what is this
"Closes:" tag and how/when to use it. The second patch modifies
checkpatch.pl to stop complaining about it.
The DRM maintainers and their mailing list have been added in Cc as they
are probably interested by these two patches as well.
[1] https://lore.kernel.org/all/3b036087d80b8c0e07a46a1dbaaf4ad0d018f8d5.1674217480.git.linux@leemhuis.info/
[2] https://lore.kernel.org/all/bb5dfd55ea2026303ab2296f4a6df3da7dd64006.1674217480.git.linux@leemhuis.info/
[3] https://lore.kernel.org/linux-doc/20230315181205.f3av7h6owqzzw64p@meerkat.local/
This patch (of 5):
Making sure a bug tracker is up to date is not an easy task. For example,
a first version of a patch fixing a tracked issue can be sent a long time
after having created the issue. But also, it can take some time to have
this patch accepted upstream in its final form. When it is done, someone
-- probably not the person who accepted the patch -- has to remember about
closing the corresponding issue.
This task of closing and tracking the patch can be done automatically by
bug trackers like GitLab [1], GitHub [2] and hopefully soon [3]
bugzilla.kernel.org when the appropriated tag is used. The two first ones
accept multiple tags but it is probably better to pick one.
