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.

2023-04-21Documentation/process: always CC responsible listsKrzysztof Kozlowski1-11/+8
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.

2023-04-19docs: process: allow Closes tags with linksMatthieu Baerts2-13/+35
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. According to commit 76f381bb77a0 ("checkpatch: warn when unknown tags are used for links"), the "Closes" tag seems to have been used in the past by a few people and it is supported by popular bug trackers. Here is how it has been used in the past: $ git log --no-merges --format=email -P --grep='^Closes: http' | \ grep '^Closes: http' | cut -d/ -f3-5 | sort | uniq -c | sort -rn 391 gitlab.freedesktop.org/drm/intel 79 github.com/multipath-tcp/mptcp_net-next 8 gitlab.freedesktop.org/drm/msm 3 gitlab.freedesktop.org/drm/amd 2 gitlab.freedesktop.org/mesa/mesa 1 patchwork.freedesktop.org/series/73320 1 gitlab.freedesktop.org/lima/linux 1 gitlab.freedesktop.org/drm/nouveau 1 github.com/ClangBuiltLinux/linux 1 bugzilla.netfilter.org/show_bug.cgi?id=1579 1 bugzilla.netfilter.org/show_bug.cgi?id=1543 1 bugzilla.netfilter.org/show_bug.cgi?id=1436 1 bugzilla.netfilter.org/show_bug.cgi?id=1427 1 bugs.debian.org/625804 Likely here, the "Closes" tag was only properly used with GitLab and GitHub. We can also see that it has been used quite a few times (and still used recently) and this is then not a "random tag that makes no sense" like it was the case with "BugLink" recently [4]. It has also been misused but that was a long time ago, when it was common to use many different random tags. checkpatch.pl script should then stop complaining about this "Closes" tag. As suggested by Thorsten [5], if this tag is accepted, it should first be described in the documentation. This is what is done here in this patch. To avoid confusion, the "Closes" should be used with any public bug report. No need to check if the underlying bug tracker supports automations. Having this tag with any kind of public bug reports allows bots like regzbot to clearly identify patches fixing a specific bug and avoid false-positives, e.g. patches mentioning it is related to an issue but not fixing it. As suggested by Thorsten [6] again, if we follow the same logic, the "Closes" tag should then be used after a "Reported-by" one. Note that thanks to this "Closes" tag, the mentioned bug trackers can also locate where a patch has been applied in different branches and repositories. If only the "Link" tag is used, the tracking can also be done but the ticket will not be closed and a manual operation will be needed. Also, these bug trackers have some safeguards: the closure is only done if a commit having the "Closes:" tag is applied in a specific branch. It will then not be closed if a random commit having the same tag is published elsewhere. Also in case of closure, a notification is sent to the owners.

2023-03-14Documentation/process: Add Linux Kernel Contribution Maturity ModelTheodore Ts'o2-0/+110
As a follow-up to a discussion at the 2021 Maintainer's Summit on the topic of maintainer recruitment and retention, the TAB took on the task of creating a document which to help companies and other organizations to grow in their ability to engage with the Linux Kernel development community, using the Maturity Model[2] framework. The goal is to encourage, in a management-friendly way, companies to allow their engineers to contribute with the upstream Linux Kernel development community, so we can grow the "talent pipeline" for contributors to become respected leaders, and eventually kernel maintainers.

2023-03-12Documentation/security-bugs: move from admin-guide/ to process/Vegard Nossum6-5/+108
Jiri Kosina, Jonathan Corbet, and Willy Tarreau all expressed a desire to move this document under process/. Create a new section for security issues in the index and group it with embargoed-hardware-issues. I'm doing this at the start of the series to make all the subsequent changes show up in 'git blame'. Existing references were updated using: git grep -l security-bugs ':!Documentation/translations/' | xargs sed -i 's|admin-guide/security-bugs|process/security-bugs|g' git grep -l security-bugs Documentation/translations/ | xargs sed -i 's|Documentation/admin-guide/security-bugs|Documentation/process/security-bugs|g' git grep -l security-bugs Documentation/translations/ | xargs sed -i '/Original:/s|\.\./admin-guide/security-bugs|\.\./process/security-bugs|g' Notably, the page is not moved in the translations (due to my lack of knowledge of these languages), but the translations have been updated to point to the new location of the original document where these references exist.

These char PCMCIA drivers are buggy[1] and receive only minimal care. It was concluded[2], that we should try to remove most pcmcia drivers completely. Let's start with these char broken one. Note that I also removed a UAPI header: include/uapi/linux/cm4000_cs.h. I found only coccinelle tests mentioning some ioctl constants from that file. But they are not actually used. Anyway, should someone complain, we may reintroduce the header (or its parts).

2023-02-26Documentation: simplify and clarify DCO contribution example languageLinus Torvalds1-1/+1
Long long ago, in a more innocent time, Greg wrote the clarification for how the DCO should work and that you couldn't make anonymous contributions, because the sign-off needed to be something we could check back with. It was 2006, and nobody reacted to the wording, the whole Facebook 'real name' controversy was a decade in the future, and nobody even thought about it. And despite the language, we've always accepted nicknames and that language was never meant to be any kind of exclusionary wording. In fact, even when it became a discussion in other adjacent projects, apparently nobody even thought to just clarify the language in the kernel docs, and instead we had projects like the CNCF that had long discussions about it, and wrote their own clarifications [1] of it. Just simplify the wording to the point where it shouldn't be causing unnecessary angst and pain, or scare away people who go by preferred naming.

There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems" [ Geert Uytterhoeven points out that that last sentence isn't true, and that there's a pending report that has a fix that is queued up - Linus ] * tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (124 commits) debugfs: drop inline constant formatting for ERR_PTR(-ERROR) OPP: fix error checking in opp_migrate_dentry() debugfs: update comment of debugfs_rename() i3c: fix device.h kernel-doc warnings dma-mapping: no need to pass a bus_type into get_arch_dma_ops() driver core: class: move EXPORT_SYMBOL_GPL() lines to the correct place Revert "driver core: add error handling for devtmpfs_create_node()" Revert "devtmpfs: add debug info to handle()" Revert "devtmpfs: remove return value of devtmpfs_delete_node()" driver core: cpu: don't hand-override the uevent bus_type callback. devtmpfs: remove return value of devtmpfs_delete_node() devtmpfs: add debug info to handle() driver core: add error handling for devtmpfs_create_node() driver core: bus: update my copyright notice driver core: bus: add bus_get_dev_root() function driver core: bus: constify bus_unregister() driver core: bus: constify some internal functions driver core: bus: constify bus_get_kset() driver core: bus: constify bus_register/unregister_notifier() driver core: remove private pointer from struct bus_type ...
2023-02-23docs: recommend using Link: whenever using Reported-by:Thorsten Leemhuis2-5/+7
Encourage developers to place Link: tag pointing to the report when they are using Reported-by: tags. Those links are often extremely useful for any code archaeologist that wants to know more about the backstory of a change than the commit message provides. That includes maintainers higher up in the patch-flow hierarchy, which is why Linus asks developers to add such links [1, 2, 3]. To quote [1]: > Again, the commit has a link to the patch *submission*, which is > almost entirely useless. There's no link to the actual problem the > patch fixes. > > [...] > > Put another way: I can see that > > Reported-by: Zhangfei Gao <zhangfei.gao@foxmail.com> > > in the commit, but I don't have a clue what the actual report was, and > there really isn't enough information in the commit itself, except for > a fairly handwavy "Device drivers might, for instance, still need to > flush operations.." > > I don't want to know what device drivers _might_ do. I would want to > have an actual pointer to what they do and where. Another reason why these links are wanted: the ongoing regression tracking efforts can only scale with them, as they allow the regression tracking bot 'regzbot' to automatically connect tracked reports with patches that are posted or committed to fix tracked regressions.

2022-10-24Documentation: process: replace outdated LTS table w/ linkNick Desaulniers1-11/+4
The existing table was a bit outdated. 3.16 was EOL in 2020. 4.4 was EOL in 2022. 5.10 is new in 2020. 5.15 is new in 2021. We'll see if 6.1 becomes LTS in 2022. Rather than keep this table updated, it does duplicate information from multiple kernel.org pages. Make one less duplication site that needs to be updated and simply refer to the kernel.org page on releases.

2022-10-24docs: netdev: offer performance feedback to contributorsJakub Kicinski1-0/+10
Some of us gotten used to producing large quantities of peer feedback at work, every 3 or 6 months. Extending the same courtesy to community members seems like a logical step. It may be hard for some folks to get validation of how important their work is internally, especially at smaller companies which don't employ many kernel experts. The concept of "peer feedback" may be a hyperscaler / silicon valley thing so YMMV. Hopefully we can build more context as we go.
