Pull slab updates from Vlastimil Babka: "This happens to be a small one (due to summer I guess), and all hardening related: - Randomized kmalloc caches, by GONG, Ruiqi. A new opt-in hardening feature to make heap spraying harder. It creates multiple (16) copies of kmalloc caches, reducing the chance of an attacker-controllable allocation site to land in the same slab as e.g. an allocation site with use-after-free vulnerability. The selection of the copy is derived from the allocation site address, including a per-boot random seed. - Stronger typing for hardened freelists in SLUB, by Jann Horn Introduces a custom type for hardened freelist entries instead of "void *" as those are not directly dereferencable. While reviewing this, I've noticed opportunities for further cleanups in that code and added those on top" * tag 'slab-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: Randomized slab caches for kmalloc() mm/slub: remove freelist_dereference() mm/slub: remove redundant kasan_reset_tag() from freelist_ptr calculations mm/slub: refactor freelist to use custom type

Pull superblock fixes from Christian Brauner: "Two follow-up fixes for the super work this cycle: - Move a misplaced lockep assertion before we potentially free the object containing the lock. - Ensure that filesystems which match superblocks in sget{_fc}() based on sb->s_fs_info are guaranteed to see a valid sb->s_fs_info as long as a superblock still appears on the filesystem type's superblock list.

Pull rust updates from Miguel Ojeda: "In terms of lines, most changes this time are on the pinned-init API and infrastructure. While we have a Rust version upgrade, and thus a bunch of changes from the vendored 'alloc' crate as usual, this time those do not account for many lines. Toolchain and infrastructure: - Upgrade to Rust 1.71.1. This is the second such upgrade, which is a smaller jump compared to the last time. This version allows us to remove the '__rust_*' allocator functions -- the compiler now generates them as expected, thus now our 'KernelAllocator' is used. It also introduces the 'offset_of!' macro in the standard library (as an unstable feature) which we will need soon. So far, we were using a declarative macro as a prerequisite in some not-yet-landed patch series, which did not support sub-fields (i.e. nested structs): #[repr(C)] struct S { a: u16, b: (u8, u8), } assert_eq!(offset_of!(S, b.1), 3); - Upgrade to bindgen 0.65.1. This is the first time we upgrade its version. Given it is a fairly big jump, it comes with a fair number of improvements/changes that affect us, such as a fix needed to support LLVM 16 as well as proper support for '__noreturn' C functions, which are now mapped to return the '!' type in Rust: void __noreturn f(void); // C pub fn f() -> !; // Rust - 'scripts/rust_is_available.sh' improvements and fixes. This series takes care of all the issues known so far and adds a few new checks to cover for even more cases, plus adds some more help texts. All this together will hopefully make problematic setups easier to identify and to be solved by users building the kernel. In addition, it adds a test suite which covers all branches of the shell script, as well as tests for the issues found so far. - Support rust-analyzer for out-of-tree modules too. - Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates. - Drop 'scripts/is_rust_module.sh' since it is not needed anymore. Macros crate: - New 'paste!' proc macro. This macro is a more flexible version of 'concat_idents!': it allows the resulting identifier to be used to declare new items and it allows to transform the identifiers before concatenating them, e.g. let x_1 = 42; paste!(let [<x _2>] = [<x _1>];); assert!(x_1 == x_2); The macro is then used for several of the pinned-init API changes in this pull. Pinned-init API: - Make '#[pin_data]' compatible with conditional compilation of fields, allowing to write code like: #[pin_data] pub struct Foo { #[cfg(CONFIG_BAR)] a: Bar, #[cfg(not(CONFIG_BAR))] a: Baz, } - New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait, which allows 'unsafe' implementations for structs where every field implements the 'Zeroable' trait, e.g.: #[derive(Zeroable)] pub struct DriverData { id: i64, buf_ptr: *mut u8, len: usize, } - Add '..Zeroable::zeroed()' syntax to the 'pin_init!' macro for zeroing all other fields, e.g.: pin_init!(Buf { buf: [1; 64], ..Zeroable::zeroed() }); - New '{,pin_}init_array_from_fn()' functions to create array initializers given a generator function, e.g.: let b: Box<[usize; 1_000]> = Box::init::<Error>( init_array_from_fn(|i| i) ).unwrap(); assert_eq!(b.len(), 1_000); assert_eq!(b[123], 123); - New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to execute a closure on the value directly after initialization, e.g.: let foo = init!(Foo { buf <- init::zeroed() }).chain(|foo| { foo.setup(); Ok(()) }); - Support arbitrary paths in init macros, instead of just identifiers and generic types. - Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and 'Opaque<T>' types. - Make initializer values inaccessible after initialization. - Make guards in the init macros hygienic. 'allocator' module: - Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing misaligned allocations when the Rust 1.71.1 upgrade is applied later in this pull. The equivalent fix for the previous compiler version (where 'KernelAllocator' is not yet used) was merged into 6.5 already, which added the 'krealloc_aligned()' function used here. - Implement 'KernelAllocator::{realloc, alloc_zeroed}' for performance, using 'krealloc_aligned()' too, which forwards the call to the C API. 'types' module: - Make 'Opaque' be '!Unpin', removing the need to add a 'PhantomPinned' field to Rust structs that contain C structs which must not be moved. - Make 'Opaque' use 'UnsafeCell' as the outer type, rather than inner. Documentation: - Suggest obtaining the source code of the Rust's 'core' library using the tarball instead of the repository.

Merge the new hardening feature to make heap spraying harder, by GONG, Ruiqi. It creates multiple (16) copies of kmalloc caches, reducing the chance of an attacker-controllable allocation site to land in the same slab as e.g. an allocation site with use-after-free vulnerability. The selection of the copy is derived from the allocation site address, including a per-boot random seed. In line with SLAB deprecation, this is a SLUB only feature, incompatible with SLUB_TINY due to the memory overhead of the extra cache copies.

For keyed filesystems that recycle superblocks based on s_fs_info or information contained therein s_fs_info must be kept as long as the superblock is on the filesystem type super list. This isn't guaranteed as s_fs_info will be freed latest in sb->kill_sb(). The fix is simply to perform notification and list removal in kill_anon_super(). Any filesystem needs to free s_fs_info after they call the kill_*() helpers. If they don't they risk use-after-free right now so fixing it here is guaranteed that s_fs_info remain valid. For block backed filesystems notifying in pass sb->kill_sb() in deactivate_locked_super() remains unproblematic and is required because multiple other block devices can be shut down after kill_block_super() has been called from a filesystem's sb->kill_sb() handler. For example, ext4 and xfs close additional devices. Block based filesystems don't depend on s_fs_info (btrfs does use s_fs_info but also uses kill_anon_super() and not kill_block_super().). Sorry for that braino. Goal should be to unify this behavior during this cycle obviously. But let's please do a simple bugfix now.

Pull scheduler updates from Ingo Molnar: - The biggest change is introduction of a new iteration of the SCHED_FAIR interactivity code: the EEVDF ("Earliest Eligible Virtual Deadline First") scheduler EEVDF too is a virtual-time scheduler, with two parameters (weight and relative deadline), compared to CFS that had weight only. It completely reworks the base scheduler: placement, preemption, picking -- everything LWN.net, as usual, has a terrific writeup about EEVDF: https://lwn.net/Articles/925371/ Preemption (both tick and wakeup) is driven by testing against a fresh pick. Because the tree is now effectively an interval tree, and the selection is no longer the 'leftmost' task, over-scheduling is less of a problem. A lot of the CFS heuristics are removed or replaced by more natural latency-space parameters & constructs In terms of expected performance regressions: we will and can fix everything where a 'good' workload misbehaves with the new scheduler, but EEVDF inevitably changes workload scheduling in a binary fashion, hopefully for the better in the overwhelming majority of cases, but in some cases it won't, especially in adversarial loads that got lucky with the previous code, such as some variants of hackbench. We are trying hard to err on the side of fixing all performance regressions, but we expect some inevitable post-release iterations of that process - Improve load-balancing on hybrid x86 systems: enable cluster scheduling (again) - Improve & fix bandwidth-scheduling on nohz systems - Improve bandwidth-throttling - Use lock guards to simplify and de-goto-ify control flow - Misc improvements, cleanups and fixes * tag 'sched-core-2023-08-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (43 commits) sched/eevdf/doc: Modify the documented knob to base_slice_ns as well sched/eevdf: Curb wakeup-preemption sched: Simplify sched_core_cpu_{starting,deactivate}() sched: Simplify try_steal_cookie() sched: Simplify sched_tick_remote() sched: Simplify sched_exec() sched: Simplify ttwu() sched: Simplify wake_up_if_idle() sched: Simplify: migrate_swap_stop() sched: Simplify sysctl_sched_uclamp_handler() sched: Simplify get_nohz_timer_target() sched/rt: sysctl_sched_rr_timeslice show default timeslice after reset sched/rt: Fix sysctl_sched_rr_timeslice intial value sched/fair: Block nohz tick_stop when cfs bandwidth in use sched, cgroup: Restore meaning to hierarchical_quota MAINTAINERS: Add Peter explicitly to the psi section sched/psi: Select KERNFS as needed sched/topology: Align group flags when removing degenerate domain sched/fair: remove util_est boosting sched/fair: Propagate enqueue flags into place_entity() ...
