git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "One of the 'small improvements all over the place' releases for us. It's hard to draw any direct comparisons because summer vacations disrupted our patch processing (and presumably - generation) quite a bit. Quick and dirty count suggests we (Paolo and I) merged a very similar number of net (632) and net-next (648) patches. This is not telling the full story either because 1/3 to 1/2 of the net-next patches also *seem* like AI-driven low priority fixes, cleanups and clarifications. We are completely overwhelmed, of course. The glimmer of hope is that we secured sufficient LLM budget and access (thank you Meta!) to run reviews with multiple frontier models on each patch. This eliminates some hallucinations. That said, in terms of review, the LLMs can only do so much. The sad truth is that our APIs (especially for rare events like PCIe errors, timeouts etc) have always been racy, and now LLMs don't let us ignore that. I expect our direction for the next release will be to tweak the reviews a little bit more, but start shifting focus to letting the LLMs take care of the busy work - managing patchwork, automating common process complaints, editing commit messages, and maybe applying patches which already got "reviewed-by" tags from people we trust... Core & protocols: - A few steps lowering rtnl_lock dependence: - per-netns netdev unregistration for select SW drivers (e.g. veth, ipvlan, tunnels) - rtnl_lock-less FIB rule changes (RTM_NEWRULE and RTM_DELRULE) -

Report the per-group user count via RTM_GETMULTICAST - Expose the route deletion reason in RTM_DELROUTE - Add a SO_RIGHTS_NOTRUNC option to UNIX sockets to enable more useful handling of LSM denials when receiving SCM_RIGHTS messages: instead of truncating the message at the first blocked fd, keep every fd slot and store the LSM errno in the blocked slot - IPv6 Segment Routing - support looking up the post-encap SID (address) in a different/specified routing table - Support PRP RedBox (interlink) creation - Support per-nexthop UDP dst port in VXLAN - Continue converting getsockopt callbacks in a number of protocols to iov_iter Ethernet: -

2026-08-04docs: security-bugs: clarify some mandatory steps for AI reportsWilly Tarreau
The security team is still seeing a lot of reports lacking a full patch and showing missing contents and formatting issues. Since AI assistants tend to be better than humans at following instructions, let's defer to coding-assistants.rst to follow mandatory steps, and insist on the plain text format, as well as asking for recipient addresses and an e-mail client setup hint to be mentioned early in the report for the reporter. Also add a link to https://github.com/masoncl/kres.git which contains way more advanced and detailed steps for those willing to go further. Tested with Opus-5 and Qwen3.6-27B-Architect-Polaris2-Fable-B-F451, both of which proceeded according to instructions.

2026-08-04docs: coding-assistant: explain important steps when looking for bugsWilly Tarreau
Due to the increasing capabilities of available AI models, it's becoming common to see them used to find bugs anywhere. Unfortunately the quality of reports (especially when they're believed to be security relevant) is still lacking a lot. Let's add a section dedicated to bug finding, explaining the few mandatory steps (noting commit ID, writing the fix from the session that found the bug, building and testing, etc). This was tested both against Qwen3.6-27B-Architect-Polaris2-Fable-B-F451 running under Hermes, and Opus-5, and both followed the instructions to the letter, verifying their results and checking threat-model.rst to decline the vulnerability aspect. At least in the current form it's expected to improve the situation a little bit.

2026-08-04docs: threat-model: move fake devices out of "non production use"Willy Tarreau
When originally writing the "fake USB device" entry, it was difficult to find a suitable section for it and it ended up in "non production use" but that doesn't fit particularly well. Actually it's very similar to crafted filesystems, it's a matter of spec violation. Both drivers and FS are written against a spec, and what the threat model doesn't cover is out-of-spec use. So let's move the entry there and rename the crafted FS entry to "Non-conforming devices and media" instead. Overall it looks more consistent. The spec was tested agains Qwen3.6-27B-Architect-Polaris2-Fable-B-F451, Opus-5 and Gemini by reading the threat-model file, then reading a tens of FS and driver fixes, and they were now all properly classified as regular bugs, except two that Gemini and Opus rightfully classified as vulns (Qwen didn't spot the security potential but that's out of our scope).

2026-08-04docs: threat-model: clarify "security bug" vs "vulnerability"Willy Tarreau
Throwing an LLM (Opus 5) at a file looking for random bugs after having read the threat model made it ignore certain bugs it found because "the threat model said they must be ignored". When asked why, the LLM rightfully reported the ambiguous wording used at a few places: "is not a security bug", which can also be read as "is not a bug", despite the rest of the document. That is particularly true when the LLM decides to look for info using grep. This change replaces "security bug" with "vulnerability" at a few places in order to remove this identified ambiguity, and uses "bugs" instead of issues in two such sentences to insist that what is described remains a bug.

2026-07-15docs: submitting-patches: Fix section structure around DCOAkira Yokosawa
Commit 5903019b2a5e ("Documentation/SubmittingPatches: convert it to ReST markup") made "DCO 1.1" a subsection under the section "Sign your work - ...". However, the DCO text is meant to be referenced in the section. Furthermore, in HTML and PDF docs, paragraphs following the DCO: then you just add a line saying: Signed-off-by: [...] [...] as it was propagated to the maintainers and ultimately to Linus, with the first SoB entry signalling primary authorship of a single author. appear to belong to the DCO, rather than to "Sign your work - ..." where it should. In reST (and other documentation tools), once you start a subsection under a section, there is no way to go back to the section. Fix the section structure by making the DCO a literal block, with indent changes made in commit 5903019b2a5e reverted. While at it, fix the same issue at "Reviewer's statement of oversight".

strncpy() has been a persistent source of bugs due to its ambiguous intended usage and frequently counter-intuitive semantics: it may not NUL-terminate the destination, and it unconditionally zero-pads to the full length, which isn't always needed. All former callers have been migrated[1] to: - strscpy() for NUL-terminated destinations - strscpy_pad() for NUL-terminated destinations needing zero-padding - strtomem_pad() for non-NUL-terminated fixed-width fields - memcpy_and_pad() for bounded copies with explicit padding - memcpy() for known-length copies Remove the generic implementation, its declaration, the FORTIFY_SOURCE wrapper, and associated tests.

2026-06-01docs: changes.rst: restore pahole 1.26 minimum (regressed by sort)Zhan Xusheng
Commit 9edd04c4189e ("docs: Raise minimum pahole version to 1.26 for KF_IMPLICIT_ARGS kfuncs") raised the minimum required pahole version from 1.22 to 1.26 in the requirements table and added a paragraph explaining the failure mode for distributions still shipping pahole v1.25 (e.g. Ubuntu 24.04 LTS). The next day, commit ece7e57afd51 ("docs: changes.rst and ver_linux: sort the lists") came through a different tree (docs vs sched_ext) and re-flowed the table alphabetically, but its base did not include 9edd04c4189e. When the two commits met in mainline, the textual rewrite of the table won and the version bump was lost. The added "Since Linux 7.0..." paragraph also disappeared. The result is that changes.rst on master (v7.1-rc5) lists pahole 1.22 again, even though sched_ext kfuncs annotated with KF_IMPLICIT_ARGS genuinely require v1.26 to produce a correct vmlinux BTF. Users on distributions with pahole v1.25 hit "func_proto incompatible with vmlinux" when loading any sched_ext BPF program (scx_simple, scx_qmap, ...) and have no documentation pointing them at the version gap.

2026-05-27kbuild: Bump minimum version of LLVM for building the kernel to 17.0.1Nathan Chancellor
The current minimum version of LLVM for building the kernel is 15.0.0. However, there are two deficiencies compared to GCC that were fixed in LLVM 17 that are starting to become more noticeable. The first was a bug in LLVM's scope checker [1], where all labels in a function were validated as potential targets of an asm goto statement, even if they were not listed in the asm goto statement as targets. This becomes particularly problematic when the cleanup attribute is used, as asm goto(... : label_a); ... label_a: ... int var __free(foo); asm goto(... : label_b); ... label_b: ... will trigger an error since the scope checker will complain that the cleanup variable would be skipped when jumping from the first asm goto to label_b (which obviously cannot happen). This issue was the catalyst for commit e2ffa15b9baa ("kbuild: Disable CC_HAS_ASM_GOTO_OUTPUT on clang < 17"). Unfortunately, this issue is reproducible with regular asm goto in addition to asm goto with outputs, so that change was not entirely sufficient to avoid the issue altogether. As asm goto has effectively been required since commit a0a12c3ed057 ("asm goto: eradicate CC_HAS_ASM_GOTO") and the usage of the cleanup attribute continues to grow across the tree, raising the minimum to a version that avoids this issue altogether is a better long term solution than attempting to workaround it at every spot where it happens. The second issue is an incompatibility with GCC 8.1+ around variables marked with const being valid constant expressions for _Static_assert and other macros [2]. With GCC 8.1 being the minimum supported version since commit 118c40b7b503 ("kbuild: require gcc-8 and binutils-2.30"), this incompatibility becomes more of a maintenance burden since only clang-15 and clang-16 are affected by it. Looking at the clang version of various major distributions through Docker images, no one should be left behind as a result of this bump, as the old ones cannot clear the current minimum of 15.0.0. archlinux:latest clang version 22.1.3 debian:oldoldstable-slim Debian clang version 11.0.1-2 debian:oldstable-slim Debian clang version 14.0.6 debian:stable-slim Debian clang version 19.1.7 (3+b1) debian:testing-slim Debian clang version 21.1.8 (3+b1) debian:unstable-slim Debian clang version 21.1.8 (7+b1) fedora:42 clang version 20.1.8 (Fedora 20.1.8-4.fc42) fedora:latest clang version 21.1.8 (Fedora 21.1.8-4.fc43) fedora:44 clang version 22.1.1 (Fedora 22.1.1-2.fc44) fedora:rawhide clang version 22.1.3 (Fedora 22.1.3-1.fc45) opensuse/leap:latest clang version 17.0.6 opensuse/tumbleweed:latest clang version 21.1.8 ubuntu:jammy Ubuntu clang version 14.0.0-1ubuntu1.1 ubuntu:noble Ubuntu clang version 18.1.3 (1ubuntu1) ubuntu:questing Ubuntu clang version 20.1.8 (0ubuntu4) ubuntu:resolute Ubuntu clang version 21.1.8 (6ubuntu1) 17.0.1 is chosen as the minimum instead of 17.0.0 to ensure that the particular version of LLVM 17 has the two aforementioned bugs fixed, as the second was fixed during the 17.0.0 release candidate phase and it was not until LLVM 18 that LLVM adopted the scheme of x.0.0 being a prerelease version and x.1.0 is a release version [3] to help with scenarios such as this.

2026-05-25docs: submitting-patches: Clarify that "reviewer" is a personKrzysztof Kozlowski
Common understanding of word "Reviewer" is: a person performing a review work [1]. Tools are not persons, thus cannot be reviewers in this term. Also tools cannot make statements and cannot take responsibility for the review. Our docs already clearly mark that "Reviewed-by" must come from a person: - "By offering my Reviewed-by: tag, I state that:" Usage of first person "I" and word "state" - "A Reviewed-by tag is *a statement of opinion* that the patch is an appropriate modification of the kernel without any remaining serious" Only a person can make a statement of opinion. - "Any interested reviewer (who has done the work) can offer a Reviewed-by" A person can offer a tag thus above does not grant the tool permission to offer a tag. However this might not be enough, so let's clarify that only a person with a known identity can state the "Reviewer's statement of oversight".

AI tools are increasingly used to assist in bug discovery. While these tools can identify valid issues, reports that are submitted without manual verification often lack context, contain speculative impact assessments, or include unnecessary formatting. Such reports increase triage effort, waste maintainers' time and may be ignored. Reports where the reporter has verified the issue and the proposed fix typically meet quality standards. This documentation outlines specific requirements for length, formatting, and impact evaluation to reduce the effort needed to deal with these reports.

2026-05-12Documentation: security-bugs: explain what is and is not a security bugWilly Tarreau
The use of automated tools to find bugs in random locations of the kernel induces a raise of security reports even if most of them should just be reported as regular bugs. This patch is an attempt at drawing a line between what qualifies as a security bug and what does not, hoping to improve the situation and ease decision on the reporter's side. It defers the enumeration to a new file, threat-model.rst, that tries to enumerate various classes of issues that are and are not security bugs. This should permit to more easily update this file for various subsystem-specific rules without having to revisit the security bug reporting guide.

With the increase of automated reports, the security team is dealing with way more messages than really needed. The reporting process works well with most teams so there is no need to systematically involve the security team in reports.

It explicitly allows the use of SPDX-FileCopyrightText which has been used already in many files. At the same time, update checkpatch to catch any "non allowed" spdx identifiers as we don't want to go overboard here.

Last two weeks feel comparable to the two weeks before the merge window. Lots of AI-aided bug discovery. A newer big source is Sashiko/Gemini (Roman Gushchin's system), which points out issues in existing code during patch review (maybe 25% of fixes here likely originating from Sashiko). Nice thing is these are often fixed by the respective maintainers, not drive-bys.

2026-04-20Documentation/process: maintainer-soc: Document purpose of defconfigsKrzysztof Kozlowski
Common mistake in commit messages of patches on mailing list adding CONFIG options to arm/multi_v7 or arm64/defconfig is saying what that patch is doing, e.g. "Enable driver foo". That is obvious from the diff part, thus explaining it does not bring any value. What brings value is to understand why "driver foo" should be in a shared, upstream defconfig, especially considering that distros have their own defconfigs and we do not care about non-upstream trees.

It is obvious that one can ask DT maintainers of something, just like one can ask anyone, so just drop the sentence. Concise documents with rules have bigger chances of actually being read by people.
