2025-10-17docs: media: mediactl: use TOC instead of file contentsMauro Carvalho Chehab2-3/+8
All we wanted were to have a way to link the comprehensive documentation with the actual symbols parsed from the header file, as this helps to identify any broken references. Use the new :toc: flag for media controller and enable warnings. Here, we need to adjust the exceptions file to setup the C namespace accordingly.

2025-10-17docs: rust: add section on imports formattingMiguel Ojeda1-0/+75
`rustfmt`, by default, formats imports in a way that is prone to conflicts while merging and rebasing, since in some cases it condenses several items into the same line. For instance, Linus mentioned [1] that the following case: use crate::{ fmt, page::AsPageIter, }; is compressed by `rustfmt` into: use crate::{fmt, page::AsPageIter}; which is undesirable. Similarly, `rustfmt` may put several items in the same line even if the braces span already multiple lines, e.g.: use kernel::{ acpi, c_str, device::{property, Core}, of, platform, }; The options that control the formatting behavior around imports are generally unstable, and `rustfmt` releases do not allow to use nightly features, unlike the compiler and other Rust tooling [2]. For the moment, we can introduce a workaround to prevent `rustfmt` from compressing the example above -- the "trailing empty comment": use crate::{ fmt, page::AsPageIter, // }; which is reminiscent of the trailing comma behavior in other formatters. We already used empty comments for formatting purposes in the past, e.g. in commit b9b701fce49a ("rust: clarify the language unstable features in use"). In addition, `rustfmt` actually reformats with a vertical layout (i.e. it does not put two items in the same line) when seeing such a comment, i.e. it doesn't just preserve the formatting, which is good in the sense that we can use it to easily reformat some imports, since it matches the style we generally want to have. A Git merge driver would help (suggested by Gary and Wedson), though maintainers would need to set it up, the diffs would still be larger and the formatting rules for imports would remain hard to predict. Thus document the style that we will follow in the coding guidelines by introducing a new section and explain how the trailing empty comment works there too. We discussed the issue with upstream Rust in our usual Rust <-> Rust for Linux meeting [3], and there have also been a few other discussions in parallel in issues [4][5] and Zulip [6]. We will see what happens, but upstream Rust has already created a subteam of `rustfmt` to try to overcome the bandwidth issue [7], which is a good signal, and some organization work has already started (e.g. tracking issues). We will continue our discussions with them about it.

2025-10-16net: Introduce net.core.bypass_prot_mem sysctl.Kuniyuki Iwashima1-0/+8
If a socket has sk->sk_bypass_prot_mem flagged, the socket opts out of the global protocol memory accounting. Let's control the flag by a new sysctl knob. The flag is written once during socket(2) and is inherited to child sockets. Tested with a script that creates local socket pairs and send()s a bunch of data without recv()ing.

2025-10-16ima: add fs_subtype condition for distinguishing FUSE instancesJann Horn1-0/+1
Linux systems often use FUSE for several different purposes, where the contents of some FUSE instances can be of more interest for auditing than others. Allow distinguishing between them based on the filesystem subtype (s_subtype) using the new condition "fs_subtype". The subtype string is supplied by userspace FUSE daemons when a FUSE connection is initialized, so policy authors who want to filter based on subtype need to ensure that FUSE mount operations are sufficiently audited or restricted.

2025-10-16ima: add dont_audit action to suppress audit actionsJann Horn1-1/+1
"measure", "appraise" and "hash" actions all have corresponding "dont_*" actions, but "audit" currently lacks that. This means it is not currently possible to have a policy that audits everything by default, but excludes specific cases. This seems to have been an oversight back when the "audit" action was added. Add a corresponding "dont_audit" action to enable such uses. Signed-off-by: Jann Horn <jannh@google.com> Signed-off-by: Mimi Zohar <zohar@linux.ibm.com>

2025-10-16dt-bindings: gpio: add QIXIS FPGA based GPIO controllerIoana Ciornei1-0/+2
Add a device tree binding for the QIXIS FPGA based GPIO controller. Depending on the board, the QIXIS FPGA exposes registers which act as a GPIO controller, each with 8 GPIO lines of fixed direction. Since each QIXIS FPGA layout has its particularities, add a separate compatible string for each board/GPIO register combination supported. Since these GPIO controllers are trivial, make use of the newly added trivial-gpio.yaml file instead of creating an entirely new one.

2025-10-15regulator: dt-bindings: rpmh-regulator: Update pmic-id DT prop info for new ↵Kamal Wadhwa1-1/+1
CMD-DB Currently, CMD-DB names for RPMH regulators follow this format: `^(smps|ldo|bob|vs)[a-n][1-9][0-9]?$` Here, the `[a-n]` value is read from the `pmic-id` DT property, which is unique to each PMIC present on the board. Note that in this older CMD-DB name format the SPMI bus on which a particular PMIC regulator exists was not apparent from its CMD-DB name. New targets like Glymur, where we have multiple SPMI buses, overcome this limitation by following a new CMD-DB name format: `^(L|S|B)[1-9][0-9]?[A-N]_E[0-3]$` Here `[A-N]_E[0-3]` part will now be read from the `pmic-id` DT prop and it includes the SPMI bus id `[0-3]` as well. However, the PMIC ID part `[A-N]` of the CMD-DB name is now unique only to the SPMI bus that the PMIC regulator is present on. which means `L1B_E0` and `L1B_E1` are both possible CMD-DB names for two different regulator LDOs present on two different SPMI buses (bus id 0 and 1) on the same board. Note that since the new `pmic-id` DT property is a combo of PMIC ID and SPMI bus ID, so its still unique to each PMIC present on the board. Update the `pmic-id` property pattern information to reflect this change in the driver handling to support this new CMD-DB naming format while maintaining backward compatiblilty with old CMD-DB naming format which is still supported for older/existing targets.

2025-10-15Merge patch series "auxdisplay: linedisp: support attribute attachment to ↵Andy Shevchenko1-0/+90
auxdisplay devices" Jean-François Lessard <jefflessard3@gmail.com> says: This series modernizes the auxdisplay line display (linedisp) library to enable seamless integration with auxdisplay parent devices while maintaining backward compatibility. The key improvement is adding attach/detach APIs that allow linedisp sysfs attributes to be bound directly to their parent auxdisplay devices avoiding child device proliferation and enabling a uniform 7-segment userspace interface across different driver architectures. This series introduces attachment infrastructure for linedisp devices. The first consumer of this API will be the TM16XX driver series. See the related patch series: auxdisplay: Add TM16xx 7-segment LED matrix display controllers driver Changes include: 1. Encapsulate container_of() usage with to_linedisp() helper function for cleaner context retrieval 2. Improve message display behavior with static padding when message length is smaller than display width 3. Add 'num_chars' read-only attribute for userspace capability discovery 4. Add attach/detach API for sysfs attributes binding to parent devices 5. Document all linedisp sysfs attributes in ABI documentation All existing linedisp_register() users remain unaffected. The new APIs enable drivers like TM16XX to integrate 7-segment functionality within their LED class device hierarchy while providing a uniform 7-segment API.
