2025-09-03netlink: specs: fou: change local-v6/peer-v6 checkAsbjørn Sloth Tønnesen
While updating the binary min-len implementation, I noticed that the only user, should AFAICT be using exact-len instead. In net/ipv4/fou_core.c FOU_ATTR_LOCAL_V6 and FOU_ATTR_PEER_V6 are only used for singular IPv6 addresses, and there are AFAICT no known implementations trying to send more, it therefore appears safe to change it to an exact-len policy. This patch therefore changes the local-v6/peer-v6 attributes to use an exact-len check, instead of a min-len check.

2025-09-03spi: spi-fsl-dspi: Target mode improvementsMark Brown
Merge series from James Clark <james.clark@linaro.org>: Improve usability of target mode by reporting FIFO errors and increasing the buffer size when DMA is used. While we're touching DMA stuff also switch to non-coherent memory, although this is unrelated to target mode. With the combination of the commit to increase the DMA buffer size and the commit to use non-coherent memory, the host mode performance figures are as follows on S32G3: # spidev_test --device /dev/spidev1.0 --bpw 8 --size <test_size> --cpha --iter 10000000 --speed 10000000 Coherent (4096 byte transfers): 6534 kbps Non-coherent: 7347 kbps Coherent (16 byte transfers): 447 kbps Non-coherent: 448 kbps Just for comparison running the same test in XSPI mode: 4096 byte transfers: 2143 kbps 16 byte transfers: 637 kbps These tests required hacking S32G3 to use DMA in host mode, although the figures should be representative of target mode too where DMA is used. And the other devices that use DMA in host mode should see similar improvements.
2025-09-03genirq: Add support for warning on long-running interrupt handlersWladislav Wiebe
Introduce a mechanism to detect and warn about prolonged interrupt handlers. With a new command-line parameter (irqhandler.duration_warn_us=), users can configure the duration threshold in microseconds when a warning in such format should be emitted: "[CPU14] long duration of IRQ[159:bad_irq_handler [long_irq]], took: 1330 us" The implementation uses local_clock() to measure the execution duration of the generic IRQ per-CPU event handler.

2025-09-03docs: dt: writing-bindings: Document node name ABI and simple-mfdKrzysztof Kozlowski
Document established Devicetree bindings maintainers review practice: 1. Device node names should not be treated as an ABI, unless for children of a device when documented. There were many patches posted using of_find_node_by_name() or of_node_name_eq() for accessing siblings or completely different nodes. These cases were introducing undocumented ABI, so they are discouraged. 2. 'simple-mfd' means children do not depend on parent device resources. 'simple-bus' is so simple, that even 'reg' properties are not applicable.

2025-09-02bonding: Remove support for use_carrierJay Vosburgh
Remove the implementation of use_carrier, the link monitoring method that utilizes ethtool or ioctl to determine the link state of an interface in a bond. Bonding will always behaves as if use_carrier=1, which relies on netif_carrier_ok() to determine the link state of interfaces. To avoid acquiring RTNL many times per second, bonding inspects link state under RCU, but not under RTNL. However, ethtool implementations in drivers may sleep, and therefore this strategy is unsuitable for use with calls into driver ethtool functions. The use_carrier option was introduced in 2003, to provide backwards compatibility for network device drivers that did not support the then-new netif_carrier_ok/on/off system. Device drivers are now expected to support netif_carrier_*, and the use_carrier backwards compatibility logic is no longer necessary. The option itself remains, but when queried always returns 1, and may only be set to 1.

2025-09-02dt-bindings: net: move ptp-timer property to ethernet-controller.yamlWei Fang
For some Ethernet controllers, the PTP timer function is not integrated. Instead, the PTP timer is a separate device and provides PTP Hardware Clock (PHC) to the Ethernet controller to use, such as NXP FMan MAC, ENETC, etc. Therefore, a property is needed to indicate this hardware relationship between the Ethernet controller and the PTP timer. Since this use case is also very common, it is better to add a generic property to ethernet-controller.yaml. According to the existing binding docs, there are two good candidates, one is the "ptp-timer" defined in fsl,fman-dtsec.yaml, and the other is the "ptimer-handle" defined in fsl,fman.yaml. From the perspective of the name, the former is more straightforward, so move the "ptp-timer" from fsl,fman-dtsec.yaml to ethernet-controller.yaml.

2025-09-02dt-bindings: ptp: add NETC Timer PTP clockWei Fang
NXP NETC (Ethernet Controller) is a multi-function PCIe Root Complex Integrated Endpoint (RCiEP), the Timer is one of its functions which provides current time with nanosecond resolution, precise periodic pulse, pulse on timeout (alarm), and time capture on external pulse support. And also supports time synchronization as required for IEEE 1588 and IEEE 802.1AS-2020. So add device tree binding doc for the PTP clock based on NETC Timer. NETC Timer has three reference clock sources, but the clock mux is inside the IP. Therefore, the driver will parse the clock name to select the desired clock source. If the clocks property is not present, NETC Timer will use the system clock of NETC IP as its reference clock. Because the Timer is a PCIe function of NETC IP, the system clock of NETC is always available to the Timer.

2025-09-02procfs: add "pidns" mount optionAleksa Sarai
Since the introduction of pid namespaces, their interaction with procfs has been entirely implicit in ways that require a lot of dancing around by programs that need to construct sandboxes with different PID namespaces. Being able to explicitly specify the pid namespace to use when constructing a procfs super block will allow programs to no longer need to fork off a process which does then does unshare(2) / setns(2) and forks again in order to construct a procfs in a pidns. So, provide a "pidns" mount option which allows such users to just explicitly state which pid namespace they want that procfs instance to use. This interface can be used with fsconfig(2) either with a file descriptor or a path: fsconfig(procfd, FSCONFIG_SET_FD, "pidns", NULL, nsfd); fsconfig(procfd, FSCONFIG_SET_STRING, "pidns", "/proc/self/ns/pid", 0); or with classic mount(2) / mount(8): // mount -t proc -o pidns=/proc/self/ns/pid proc /tmp/proc mount("proc", "/tmp/proc", "proc", MS_..., "pidns=/proc/self/ns/pid"); As this new API is effectively shorthand for setns(2) followed by mount(2), the permission model for this mirrors pidns_install() to avoid opening up new attack surfaces by loosening the existing permission model. In order to avoid having to RCU-protect all users of proc_pid_ns() (to avoid UAFs), attempting to reconfigure an existing procfs instance's pid namespace will error out with -EBUSY. Creating new procfs instances is quite cheap, so this should not be an impediment to most users, and lets us avoid a lot of churn in fs/proc/* for a feature that it seems unlikely userspace would use.
