2025-06-05netlink: specs: rt-link: decode ip6greJakub Kicinski
Driver tests now require GRE tunnels, while we don't configure them with YNL, YNL will complain when it sees link types it doesn't recognize. Teach it decoding ip6gre tunnels. The attrs are largely the same as IPv4 GRE. Correct the type of encap-limit, but note that this attr is only used in ip6gre, so the mistake didn't matter until now.

2025-06-04Merge tag 'rust-6.16' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux Pull Rust updates from Miguel Ojeda: "Toolchain and infrastructure: - KUnit '#[test]'s: - Support KUnit-mapped 'assert!' macros. The support that landed last cycle was very basic, and the 'assert!' macros panicked since they were the standard library ones. Now, they are mapped to the KUnit ones in a similar way to how is done for doctests, reusing the infrastructure there. With this, a failing test like: #[test] fn my_first_test() { assert_eq!(42, 43); } will report: # my_first_test: ASSERTION FAILED at rust/kernel/lib.rs:251 Expected 42 == 43 to be true, but is false # my_first_test.speed: normal not ok 1 my_first_test - Support tests with checked 'Result' return types. The return value of test functions that return a 'Result' will be checked, thus one can now easily catch errors when e.g. using the '?' operator in tests. With this, a failing test like: #[test] fn my_test() -> Result { f()?; Ok(()) } will report: # my_test: ASSERTION FAILED at rust/kernel/lib.rs:321 Expected is_test_result_ok(my_test()) to be true, but is false # my_test.speed: normal not ok 1 my_test - Add 'kunit_tests' to the prelude. - Clarify the remaining language unstable features in use. - Compile 'core' with edition 2024 for Rust >= 1.87. - Workaround 'bindgen' issue with forward references to 'enum' types. - objtool: relax slice condition to cover more 'noreturn' functions. - Use absolute paths in macros referencing 'core' and 'kernel' crates. - Skip '-mno-fdpic' flag for bindgen in GCC 32-bit arm builds. - Clean some 'doc_markdown' lint hits -- we may enable it later on. 'kernel' crate: - 'alloc' module: - 'Box': support for type coercion, e.g. 'Box<T>' to 'Box<dyn U>' if 'T' implements 'U'. - 'Vec': implement new methods (prerequisites for nova-core and binder): 'truncate', 'resize', 'clear', 'pop', 'push_within_capacity' (with new error type 'PushError'), 'drain_all', 'retain', 'remove' (with new error type 'RemoveError'), insert_within_capacity' (with new error type 'InsertError'). In addition, simplify 'push' using 'spare_capacity_mut', split 'set_len' into 'inc_len' and 'dec_len', add type invariant 'len <= capacity' and simplify 'truncate' using 'dec_len'. - 'time' module: - Morph the Rust hrtimer subsystem into the Rust timekeeping subsystem, covering delay, sleep, timekeeping, timers. This new subsystem has all the relevant timekeeping C maintainers listed in the entry. - Replace 'Ktime' with 'Delta' and 'Instant' types to represent a duration of time and a point in time. - Temporarily add 'Ktime' to 'hrtimer' module to allow 'hrtimer' to delay converting to 'Instant' and 'Delta'. - 'xarray' module: - Add a Rust abstraction for the 'xarray' data structure. This abstraction allows Rust code to leverage the 'xarray' to store types that implement 'ForeignOwnable'. This support is a dependency for memory backing feature of the Rust null block driver, which is waiting to be merged. - Set up an entry in 'MAINTAINERS' for the XArray Rust support. Patches will go to the new Rust XArray tree and then via the Rust subsystem tree for now. - Allow 'ForeignOwnable' to carry information about the pointed-to type. This helps asserting alignment requirements for the pointer passed to the foreign language. - 'container_of!': retain pointer mut-ness and add a compile-time check of the type of the first parameter ('$field_ptr'). - Support optional message in 'static_assert!'. - Add C FFI types (e.g. 'c_int') to the prelude. - 'str' module: simplify KUnit tests 'format!' macro, convert 'rusttest' tests into KUnit, take advantage of the '-> Result' support in KUnit '#[test]'s. - 'list' module: add examples for 'List', fix path of 'assert_pinned!' (so far unused macro rule). - 'workqueue' module: remove 'HasWork::OFFSET'. - 'page' module: add 'inline' attribute. 'macros' crate: - 'module' macro: place 'cleanup_module()' in '.exit.text' section. 'pin-init' crate: - Add 'Wrapper<T>' trait for creating pin-initializers for wrapper structs with a structurally pinned value such as 'UnsafeCell<T>' or 'MaybeUninit<T>'. - Add 'MaybeZeroable' derive macro to try to derive 'Zeroable', but not error if not all fields implement it. This is needed to derive 'Zeroable' for all bindgen-generated structs. - Add 'unsafe fn cast_[pin_]init()' functions to unsafely change the initialized type of an initializer. These are utilized by the 'Wrapper<T>' implementations. - Add support for visibility in 'Zeroable' derive macro. - Add support for 'union's in 'Zeroable' derive macro. - Upstream dev news: streamline CI, fix some bugs. Add new workflows to check if the user-space version and the one in the kernel tree have diverged. Use the issues tab [1] to track them, which should help folks report and diagnose issues w.r.t. 'pin-init' better. [1] https://github.com/rust-for-linux/pin-init/issues Documentation: - Testing: add docs on the new KUnit '#[test]' tests. - Coding guidelines: explain that '///' vs. '//' applies to private items too. Add section on C FFI types. - Quick Start guide: update Ubuntu instructions and split them into "25.04" and "24.04 LTS and older".

2025-06-02dt-bindings: pwm: adi,axi-pwmgen: Fix clocksDavid Lechner
Fix a shortcoming in the bindings that doesn't allow for a separate external clock. The AXI PWMGEN IP block has a compile option ASYNC_CLK_EN that allows the use of an external clock for the PWM output separate from the AXI clock that runs the peripheral. This was missed in the original bindings and so users were writing dts files where the one and only clock specified would be the external clock, if there was one, incorrectly missing the separate AXI clock.

2025-06-02arm64: Add override for MPAMXi Ruoyao
As the message of the commit 09e6b306f3ba ("arm64: cpufeature: discover CPU support for MPAM") already states, if a buggy firmware fails to either enable MPAM or emulate the trap as if it were disabled, the kernel will just fail to boot. While upgrading the firmware should be the best solution, we have some hardware of which the vendor have made no response 2 months after we requested a firmware update. Allow overriding it so our devices don't become some e-waste.

2025-05-31sched/numa: add statistics of numa balance taskChen Yu
On systems with NUMA balancing enabled, it has been found that tracking task activities resulting from NUMA balancing is beneficial. NUMA balancing employs two mechanisms for task migration: one is to migrate a task to an idle CPU within its preferred node, and the other is to swap tasks located on different nodes when they are on each other's preferred nodes. The kernel already provides NUMA page migration statistics in /sys/fs/cgroup/mytest/memory.stat and /proc/{PID}/sched. However, it lacks statistics regarding task migration and swapping. Therefore, relevant counts for task migration and swapping should be added. The following two new fields: numa_task_migrated numa_task_swapped will be shown in /sys/fs/cgroup/{GROUP}/memory.stat, /proc/{PID}/sched and /proc/vmstat. Introducing both per-task and per-memory cgroup (memcg) NUMA balancing statistics facilitates a rapid evaluation of the performance and resource utilization of the target workload. For instance, users can first identify the container with high NUMA balancing activity and then further pinpoint a specific task within that group, and subsequently adjust the memory policy for that task. In short, although it is possible to iterate through /proc/$pid/sched to locate the problematic task, the introduction of aggregated NUMA balancing activity for tasks within each memcg can assist users in identifying the task more efficiently through a divide-and-conquer approach. As Libo Chen pointed out, the memcg event relies on the text names in vmstat_text, and /proc/vmstat generates corresponding items based on vmstat_text. Thus, the relevant task migration and swapping events introduced in vmstat_text also need to be populated by count_vm_numa_event(), otherwise these values are zero in /proc/vmstat. In theory, task migration and swap events are part of the scheduler's activities. The reason for exposing them through the memory.stat/vmstat interface is that we already have NUMA balancing statistics in memory.stat/vmstat, and these events are closely related to each other. Following Shakeel's suggestion, we describe the end-to-end flow/story of all these events occurring on a timeline for future reference: The goal of NUMA balancing is to co-locate a task and its memory pages on the same NUMA node. There are two strategies: migrate the pages to the task's node, or migrate the task to the node where its pages reside. Suppose a task p1 is running on Node 0, but its pages are located on Node 1. NUMA page fault statistics for p1 reveal its "page footprint" across nodes. If NUMA balancing detects that most of p1's pages are on Node 1: 1.Page Migration Attempt: The Numa balance first tries to migrate p1's pages to Node 0. The numa_page_migrate counter increments. 2.Task Migration Strategies: After the page migration finishes, Numa balance checks every 1 second to see if p1 can be migrated to Node 1. Case 2.1: Idle CPU Available If Node 1 has an idle CPU, p1 is directly scheduled there. This event is logged as numa_task_migrated. Case 2.2: No Idle CPU (Task Swap) If all CPUs on Node1 are busy, direct migration could cause CPU contention or load imbalance. Instead: The Numa balance selects a candidate task p2 on Node 1 that prefers Node 0 (e.g., due to its own page footprint). p1 and p2 are swapped. This cross-node swap is recorded as numa_task_swapped.
