docs: submitting-patches: adjust Fixes definition slightly
Every now and then people send stylistic patches and use Fixes purely to refer to a commit which added the ugly or unnecessary code. Reword the docs about Fixes. It should hopefully be enough to lead with the word "bug" rather than "issue". We can add more verbiage later, tho, let's try the word swap first. I always feel like the more words the smaller the chance someone will actually read the docs.

Documentation/process: maintainer-soc: Use "DTS" instead of "devicetree"
Devicetree is a data structure and it is a bit generic term, because some treat Devicetree bindings as Devicetree. What the SoC maintainers profile is mentioning in ABI stability are the Devicetree sources, so DTS files. It is also more common during reviews to refer to these as per "DTS" instead "devicetree". Clarify that by using "DTS" name in few more places.

docs: netdev: refine the clean-up patch examples
We discourage sending trivial patches to clean up checkpatch warnings. There are other tools which lead to patches of similarly low value like some coccicheck warnings. The warnings are useful for new code but fixing them in the existing code base is a waste of review time. Broaden the example given in the doc a little bit.

Documentation: smooth the text flow in the security bug reporting process
The text was presenting the team, the the e-mail address, then some of the expectations, then what form of e-mail is expected. By switching the e-mail paragraph two paragraphs later and dropping the "Contact" sub-section, we can have a more natural flow that presents the team, then its expectation, then how to best contribute, then where to send. And more importantly, it increases the chances that reporters have read the prerequisites before finding the e-mail address.

Documentation: clarify the expected collaboration with security bugs reporters
Some bug reports sent to the security team sometimes lack any explanation, are only AI-generated without verification, or sometimes it can simply be difficult to have a conversation with an invisible reporter belonging to an opaque team. This fortunately remains rare but the trend has been steadily increasing over the last years and it seems important to clarify what developers expect from reporters to avoid frustration on any side and keep the process efficient.

docs: changes: better document Python needs
Python is listed as an optional dependency, but this is not true, as: 1) arm (multi_v7_defconfig and other defconfigs) and arm64 defconfig needs it due to DRM_MSM dependencies; 2) CONFIG_LTO_CLANG runs a python script at scripts/Makefile.vmlinux_o; 3) kernel-doc is called during compilation when some DRM options like CONFIG_DRM_I915_WERROR are enabled; 4) allyesconfig/allmodconfig will enable CONFIG_* dependencies that needs it; 5) besides DRM, other subsystems seem to have logic calling *.py scripts. So, better document that and change the dependency from optional to mandatory to reflect the current needs.

It has been a relatively busy cycle for docs, especially the build system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the turn of
the millennium. Over the following 25 years, it accumulated a vast
amount of cruft, all in a language few people want to deal with anymore.
Mauro's Python replacement in 6.16 faithfully reproduced all of the cruft
in the hope of avoiding regressions. Now that we have a more reasonable
code base, though, we can work on cleaning it up; many of the changes
this time around are toward that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository links.
...and lots of fixes and updates.

require gcc-8 and binutils-2.30
x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler but additionally include toolchains that remain supported. With the new minimum toolchain versions, a number of workarounds for older versions can be dropped, in particular on x86_64 and arm64. Importantly, the updated compiler version allows removing two of the five remaining gcc plugins, as support for sancov and structeak features is already included in modern compiler versions. I tried collecting the known changes that are possible based on the new toolchain version, but expect that more cleanups will be possible. Since this touches multiple architectures, I merged the patches through the asm-generic tree. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmg6vNMACgkQmmx57+YA GNkOmg/+LtR9B2P27GPBeG8HnLTZ8hKELiyYeSk6ZFgQv5hevE37HV35Yru7e7gu wcF6CgYr8ff4CVcHM7y0790oGew1thkqq5CklFIH0EwCDJx/mWfZR1SS2jfZIEWM HSDOlQQd1S8oWia14tSnQos3nW3CB9/ABVTHH+Wvl3xn48WMRvgK2LJgGLuxJrt8 5DD9auHiLjchWB5tB4DU98IgWWgFUGMTsI6IayZ4dkF4CdWqd89h0Y3pjJYeBgHS mPxzR2q8WjEmG9hp7QuZQgn/pAYleJAwHvvkoLrkQ2ieqx3FjWiwFbQp4CG1Sc8L eBR1lnkqS2z/e7xJLfe86fOoKWWu4I0tZKhRan/0+UOGm5nXrGpqSxKS8ZDsRuAp 3fvyhIp1cYSa7Xkok8BFhLEFR0tguXJXnXBc3tWE5VXIfFNd0Ohh1GUYhXDAqWKh i0jN9dSNhokM3AqBi6qZl5kmBnRA3UsIaOg3QRrqN8IlBPp+u7i5xsrJIUWvD95o TO06admmLcCJT8n6ZfNVfRjBgzu8+t54UVaDx9YYwxoNGOSFwqOb8CSPTWPxLmDr RKDUOvO8DBlP7uFz9neP+LxluA3DjurRZvb0z0AmCZ8/RXEmTMCyfP5a6esxquXt 0Bqo6hM9q+TeXTHNS1CNvqLSWWikw+AzS/ZPPvriYFn5lxtbq6c= =pdDC -----END PGP SIGNATURE----- Merge tag 'gcc-minimum-version-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull compiler version requirement update from Arnd Bergmann: "Require gcc-8 and binutils-2.30 x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those.

Not a huge number of changes this development cycle, here's the summary
of what is included in here:
- kernfs locking tweaks, pushing some global locks down into a per-fs
image lock
- rust driver core and pci device bindings added for new features.
- sysfs const work for bin_attributes. This churn should now be
completed for those types of attributes
- auxbus device creation helpers added
- fauxbus fix for creating sysfs files after the probe completed
properly
- other tiny updates for driver core things.
All of these have been in linux-next for over a week with no reported

Networking changes for 6.15.
Core & protocols
----------------
- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls).
- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked)
in BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream performance
up to 2x.
- Improve performance of contended connect() by 200% by searching
for an available 4-tuple under RCU rather than a spin lock.
Bring an additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles.
There are up to 4 namespace roles but we used to have just 2 netns
pointer arguments, interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.
- Add a new sysctl and sockopt for capping max retransmit timeout
in TCP.
- Support masking port and DSCP in routing rule matches.
- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.
- Support specifying at what time packet should be sent on AF_XDP
sockets.
- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users.
- Add Netlink YAML spec for WiFi (nl80211) and conntrack.
- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols
which only need to be exported when IPv6 support is built as a module.
- Age FDB entries based on Rx not Tx traffic in VxLAN, similar
to normal bridging.
- Allow users to specify source port range for GENEVE tunnels.
- netconsole: allow attaching kernel release, CPU ID and task name
to messages as metadata
Driver API
----------
- Continue rework / fixing of Energy Efficient Ethernet (EEE) across
the SW layers. Delegate the responsibilities to phylink where possible.
Improve its handling in phylib.

It has been a reasonably busy cycle for docs...
- Significant changes throughout the tree to bring Python code up to
current standards and raise the minimum Python required to 3.9. Much of
this is preparatory to replacing the ancient Perl scripts/kernel-doc
horror with a slightly less horrifying Python implementation, expected
for 6.16.
- Update the minimum Sphinx required to 3.4.3, allowing us to remove a
bunch of older compatibility code.
- Rework and improve the generation of the ABI documentation.
(All of the above done by Mauro)
- Lots of translation updates. Alex Shi and Yanteng Si are taking on
responsibility for the Chinese translations going forward; that work will
still get to you via docs-next
- Try to standardize the format for indicating a developer's affiliation in
commit tags.
- Clarify the TAB's role in CoC enforcement actions.
- Try to spell out the rules for when a commit tag can name another
developer without their explicit permission.
Plus lots of other typo fixes and updates.

docs: clarify rules wrt tagging other people
Point out that explicit permission is usually needed to tag other people in changes, but mention that implicit permission can be sufficient in certain cases. This fixes slight inconsistencies between Reported-by: and Suggested-by: and makes the usage more intuitive. While at it, explicitly mention the dangers of our bugzilla instance, as it makes it easy to forget that email addresses visible there are only shown to logged-in users. The latter is not a theoretical issue, as one maintainer mentioned that his employer received a EU GDPR (general data protection regulation) complaint after exposing a email address used in bugzilla through a tag in a patch description.

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.

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.

docs: use toctree :caption: and move introduction
The canonical way to add a heading to the ToC is to use :caption:. Do that. Let's also move the introduction to the top of the document to be consistent with most other documents.
