git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl Pull sysctl updates from Joel Granados: - Move sysctls out of the kern_table array This is the final move of ctl_tables into their respective subsystems. Only 5 (out of the original 50) will remain in kernel/sysctl.c file; these handle either sysctl or common arch variables. By decentralizing sysctl registrations, subsystem maintainers regain control over their sysctl interfaces, improving maintainability and reducing the likelihood of merge conflicts. - docs: Remove false positives from check-sysctl-docs Stopped falsely identifying sysctls as undocumented or unimplemented in the check-sysctl-docs script.

Certain targets disable kstack_erase by filtering out KSTACK_ERASE_CFLAGS rather than adding DISABLE_KSTACK_ERASE. The renaming to kstack_erase missed the CFLAGS export, which broke those build targets (e.g. x86 vdso32).

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull fileattr updates from Christian Brauner: "This introduces the new file_getattr() and file_setattr() system calls after lengthy discussions. Both system calls serve as successors and extensible companions to the FS_IOC_FSGETXATTR and FS_IOC_FSSETXATTR system calls which have started to show their age in addition to being named in a way that makes it easy to conflate them with extended attribute related operations. These syscalls allow userspace to set filesystem inode attributes on special files. One of the usage examples is the XFS quota projects. XFS has project quotas which could be attached to a directory. All new inodes in these directories inherit project ID set on parent directory. The project is created from userspace by opening and calling FS_IOC_FSSETXATTR on each inode. This is not possible for special files such as FIFO, SOCK, BLK etc. Therefore, some inodes are left with empty project ID. Those inodes then are not shown in the quota accounting but still exist in the directory. This is not critical but in the case when special files are created in the directory with already existing project quota, these new inodes inherit extended attributes. This creates a mix of special files with and without attributes. Moreover, special files with attributes don't have a possibility to become clear or change the attributes. This, in turn, prevents userspace from re-creating quota project on these existing files. In addition, these new system calls allow the implementation of additional attributes that we couldn't or didn't want to fit into the legacy ioctls anymore" * tag 'vfs-6.17-rc1.fileattr' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fs: tighten a sanity check in file_attr_to_fileattr() tree-wide: s/struct fileattr/struct file_kattr/g fs: introduce file_getattr and file_setattr syscalls fs: prepare for extending file_get/setattr() fs: make vfs_fileattr_[get|set] return -EOPNOTSUPP selinux: implement inode_file_[g|s]etattr hooks lsm: introduce new hooks for setting/getting inode fsxattr fs: split fileattr related helpers into separate file

In preparation for adding Clang sanitizer coverage stack depth tracking that can support stack depth callbacks: - Add the new top-level CONFIG_KSTACK_ERASE option which will be implemented either with the stackleak GCC plugin, or with the Clang stack depth callback support. - Rename CONFIG_GCC_PLUGIN_STACKLEAK as needed to CONFIG_KSTACK_ERASE, but keep it for anything specific to the GCC plugin itself. - Rename all exposed "STACKLEAK" names and files to "KSTACK_ERASE" (named for what it does rather than what it protects against), but leave as many of the internals alone as possible to avoid even more churn. While here, also split "prev_lowest_stack" into CONFIG_KSTACK_ERASE_METRICS, since that's the only place it is referenced from.

2025-07-14rust: use `#[used(compiler)]` to fix build and `modpost` with Rust >= 1.89.0Miguel Ojeda
Starting with Rust 1.89.0 (expected 2025-08-07), the Rust compiler fails to build the `rusttest` target due to undefined references such as: kernel...-cgu.0:(.text....+0x116): undefined reference to `rust_helper_kunit_get_current_test' Moreover, tooling like `modpost` gets confused: WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/gpu/drm/nova/nova.o ERROR: modpost: missing MODULE_LICENSE() in drivers/gpu/nova-core/nova_core.o The reason behind both issues is that the Rust compiler will now [1] treat `#[used]` as `#[used(linker)]` instead of `#[used(compiler)]` for our targets. This means that the retain section flag (`R`, `SHF_GNU_RETAIN`) will be used and that they will be marked as `unique` too, with different IDs. In turn, that means we end up with undefined references that did not get discarded in `rusttest` and that multiple `.modinfo` sections are generated, which confuse tooling like `modpost` because they only expect one. Thus start using `#[used(compiler)]` to keep the previous behavior and to be explicit about what we want. Sadly, it is an unstable feature (`used_with_arg`) [2] -- we will talk to upstream Rust about it. The good news is that it has been available for a long time (Rust >= 1.60) [3]. The changes should also be fine for previous Rust versions, since they behave the same way as before [4]. Alternatively, we could use `#[no_mangle]` or `#[export_name = ...]` since those still behave like `#[used(compiler)]`, but of course it is not really what we want to express, and it requires other changes to avoid symbol conflicts.

2025-07-10scripts/gdb/symbols: make lx-symbols skip the s390 decompressorIlya Leoshkevich
When one starts QEMU with the -S flag and attaches GDB, the kernel is not yet loaded, and the current instruction is an entry point to the decompressor. In case the intention is to debug the early kernel boot, and not the decompressor, e.g., put a breakpoint on some kernel function and see all the invocations, one has to skip the decompressor. There are many ways to do this, and so far people wrote private scripts or memorized certain command sequences. Make it work out of the box like this: $ gdb -ex 'target remote :6812' -ex 'source vmlinux-gdb.py' vmlinux Remote debugging using :6812 0x0000000000010000 in ??

2025-07-09scripts/gdb: fix interrupts.py after maple tree conversionFlorian Fainelli
In commit 721255b9826b ("genirq: Use a maple tree for interrupt descriptor management"), the irq_desc_tree was replaced with a sparse_irqs tree using a maple tree structure. Since the script looked for the irq_desc_tree symbol which is no longer available, no interrupts would be printed and the script output would not be useful anymore. In addition to looking up the correct symbol (sparse_irqs), a new module (mapletree.py) is added whose mtree_load() implementation is largely copied after the C version and uses the same variable and intermediate function names wherever possible to ensure that both the C and Python version be updated in the future. This restores the scripts' output to match that of /proc/interrupts.

2025-07-02fs: introduce file_getattr and file_setattr syscallsAndrey Albershteyn
Introduce file_getattr() and file_setattr() syscalls to manipulate inode extended attributes. The syscalls takes pair of file descriptor and pathname. Then it operates on inode opened accroding to openat() semantics. The struct file_attr is passed to obtain/change extended attributes. This is an alternative to FS_IOC_FSSETXATTR ioctl with a difference that file don't need to be open as we can reference it with a path instead of fd. By having this we can manipulated inode extended attributes not only on regular files but also on special ones. This is not possible with FS_IOC_FSSETXATTR ioctl as with special files we can not call ioctl() directly on the filesystem inode using fd. This patch adds two new syscalls which allows userspace to get/set extended inode attributes on special files by using parent directory and a path - *at() like syscall.

2025-06-16gendwarfksyms: Fix structure type overridesSami Tolvanen
As we always iterate through the entire die_map when expanding type strings, recursively processing referenced types in type_expand_child() is not actually necessary. Furthermore, the type_string kABI rule added in commit c9083467f7b9 ("gendwarfksyms: Add a kABI rule to override type strings") can fail to override type strings for structures due to a missing kabi_get_type_string() check in this function. Fix the issue by dropping the unnecessary recursion and moving the override check to type_expand(). Note that symbol versions are otherwise unchanged with this patch.

2025-06-07genksyms: Fix enum consts from a reference affecting new valuesPetr Pavlu
Enumeration constants read from a symbol reference file can incorrectly affect new enumeration constants parsed from an actual input file. Example: $ cat test.c enum { E_A, E_B, E_MAX }; struct bar { int mem[E_MAX]; }; int foo(struct bar *a) {} __GENKSYMS_EXPORT_SYMBOL(foo); $ cat test.c | ./scripts/genksyms/genksyms -T test.0.symtypes #SYMVER foo 0x070d854d $ cat test.0.symtypes E#E_MAX 2 s#bar struct bar { int mem [ E#E_MAX ] ; } foo int foo ( s#bar * ) $ cat test.c | ./scripts/genksyms/genksyms -T test.1.symtypes -r test.0.symtypes <stdin>:4: warning: foo: modversion changed because of changes in enum constant E_MAX #SYMVER foo 0x9c9dfd81 $ cat test.1.symtypes E#E_MAX ( 2 ) + 3 s#bar struct bar { int mem [ E#E_MAX ] ; } foo int foo ( s#bar * ) The __add_symbol() function includes logic to handle the incrementation of enumeration values, but this code is also invoked when reading a reference file. As a result, the variables last_enum_expr and enum_counter might be incorrectly set after reading the reference file, which later affects parsing of the actual input. Fix the problem by splitting the logic for the incrementation of enumeration values into a separate function process_enum() and call it from __add_symbol() only when processing non-reference data.

2025-06-06scripts/misc-check: check unnecessary #include <linux/export.h> when W=1Masahiro Yamada
Another issue with <linux/export.h> is that it is sometimes included even when EXPORT_SYMBOL() is not used at all. Some headers (e.g. include/linux/linkage.h>) cannot be fixed for now for the reason described in the previous commit. This commit adds a warning for *.c files that include <linux/export.h> but do not use EXPORT_SYMBOL() when the kernel is built with W=1. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-06-06scripts/misc-check: check missing #include <linux/export.h> when W=1Masahiro Yamada
The problem was described in commit 5b20755b7780 ("init: move THIS_MODULE from <linux/export.h> to <linux/init.h>"). To summarize it again here: <linux/export.h> is included by most C files, even though only some of them actually export symbols. This is because some headers, such as include/linux/{module.h,linkage}, needlessly include <linux/export.h>. I have added a more detailed explanation in the comments of scripts/misc-check. This problem will be fixed in two steps: 1. Add #include <linux/export.h> directly to C files that use EXPORT_SYMBOL() 2. Remove #include <linux/export.h> from header files that do not use EXPORT_SYMBOL() This commit addresses step 1; scripts/misc-check will warn about *.[ch] files that use EXPORT_SYMBOL() but do not include <linux/export.h>. This check is only triggered when the kernel is built with W=1. We need to fix 4000+ files. I hope others will help with this effort. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

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.

2025-05-31kcov: rust: add flags for KCOV with RustAlice Ryhl
Rust code is currently not instrumented properly when KCOV is enabled. Thus, add the relevant flags to perform instrumentation correctly. This is necessary for efficient fuzzing of Rust code. The sanitizer-coverage features of LLVM have existed for long enough that they are available on any LLVM version supported by rustc, so we do not need any Kconfig feature detection. The coverage level is set to 3, as that is the level needed by trace-pc. We do not instrument `core` since when we fuzz the kernel, we are looking for bugs in the kernel, not the Rust stdlib.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull compiler version requirement update from Arnd Bergmann: "Require gcc-8 and binutils-2.30 x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler but additionally include toolchains that remain supported. With the new minimum toolchain versions, a number of workarounds for older versions can be dropped, in particular on x86_64 and arm64. Importantly, the updated compiler version allows removing two of the five remaining gcc plugins, as support for sancov and structeak features is already included in modern compiler versions. I tried collecting the known changes that are possible based on the new toolchain version, but expect that more cleanups will be possible. Since this touches multiple architectures, I merged the patches through the asm-generic tree." * tag 'gcc-minimum-version-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: Makefile.kcov: apply needed compiler option unconditionally in CFLAGS_KCOV Documentation: update binutils-2.30 version reference gcc-plugins: remove SANCOV gcc plugin Kbuild: remove structleak gcc plugin arm64: drop binutils version checks raid6: skip avx512 checks kbuild: require gcc-8 and binutils-2.30

Pull kvm updates from Paolo Bonzini: "As far as x86 goes this pull request "only" includes TDX host support. Quotes are appropriate because (at 6k lines and 100+ commits) it is much bigger than the rest, which will come later this week and consists mostly of bugfixes and selftests. s390 changes will also come in the second batch. ARM: - Add large stage-2 mapping (THP) support for non-protected guests when pKVM is enabled, clawing back some performance. - Enable nested virtualisation support on systems that support it, though it is disabled by default. - Add UBSAN support to the standalone EL2 object used in nVHE/hVHE and protected modes. - Large rework of the way KVM tracks architecture features and links them with the effects of control bits. While this has no functional impact, it ensures correctness of emulation (the data is automatically extracted from the published JSON files), and helps dealing with the evolution of the architecture. - Significant changes to the way pKVM tracks ownership of pages, avoiding page table walks by storing the state in the hypervisor's vmemmap. This in turn enables the THP support described above. - New selftest checking the pKVM ownership transition rules - Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests even if the host didn't have it. - Fixes for the address translation emulation, which happened to be rather buggy in some specific contexts. - Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N from the number of counters exposed to a guest and addressing a number of issues in the process. - Add a new selftest for the SVE host state being corrupted by a guest. - Keep HCR_EL2.xMO set at all times for systems running with the kernel at EL2, ensuring that the window for interrupts is slightly bigger, and avoiding a pretty bad erratum on the AmpereOne HW. - Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers from a pretty bad case of TLB corruption unless accesses to HCR_EL2 are heavily synchronised. - Add a per-VM, per-ITS debugfs entry to dump the state of the ITS tables in a human-friendly fashion. - and the usual random cleanups. LoongArch: - Don't flush tlb if the host supports hardware page table walks. - Add KVM selftests support. RISC-V: - Add vector registers to get-reg-list selftest - VCPU reset related improvements - Remove scounteren initialization from VCPU reset - Support VCPU reset from userspace using set_mpstate() ioctl x86: - Initial support for TDX in KVM. This finally makes it possible to use the TDX module to run confidential guests on Intel processors. This is quite a large series, including support for private page tables (managed by the TDX module and mirrored in KVM for efficiency), forwarding some TDVMCALLs to userspace, and handling several special VM exits from the TDX module. This has been in the works for literally years and it's not really possible to describe everything here, so I'll defer to the various merge commits up to and including commit 7bcf7246c42a ('Merge branch 'kvm-tdx-finish-initial' into HEAD')" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (248 commits) x86/tdx: mark tdh_vp_enter() as __flatten Documentation: virt/kvm: remove unreferenced footnote RISC-V: KVM: lock the correct mp_state during reset KVM: arm64: Fix documentation for vgic_its_iter_next() KVM: arm64: np-guest CMOs with PMD_SIZE fixmap KVM: arm64: Stage-2 huge mappings for np-guests KVM: arm64: Add a range to pkvm_mappings KVM: arm64: Convert pkvm_mappings to interval tree KVM: arm64: Add a range to __pkvm_host_test_clear_young_guest() KVM: arm64: Add a range to __pkvm_host_wrprotect_guest() KVM: arm64: Add a range to __pkvm_host_unshare_guest() KVM: arm64: Add a range to __pkvm_host_share_guest() KVM: arm64: Introduce for_each_hyp_page KVM: arm64: Handle huge mappings for np-guest CMOs KVM: arm64: nv: Release faulted-in VNCR page from mmu_lock critical section KVM: arm64: nv: Handle TLBI S1E2 for VNCR invalidation with mmu_lock held KVM: arm64: nv: Hold mmu_lock when invalidating VNCR SW-TLB before translating RISC-V: KVM: add KVM_CAP_RISCV_MP_STATE_RESET RISC-V: KVM: Remove scounteren initialization KVM: RISC-V: remove unnecessary SBI reset state ...

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core: - Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire. - Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster. - Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability. - Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks. - Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests. - Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT. - Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages. Netfilter: - Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface. - Implement support for wildcard netdevice in netdev basechain and flowtables. - Integrate conntrack information into nft trace infrastructure. - Export set count and backend name to userspace, for better introspection. BPF: - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command. - Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets. Protocols: - Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%. - Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server. - Improve TCP multipath routing, so that the sources address always matches the nexthop device. - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs. - Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path. - Extend TCP drop-reason support to cover PAWS checks. Driver API: - Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags. - Converted several device drivers to timestamping APIs. - Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs. Tests and tooling: - Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration. - Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output. - Extend MPTCP selftests to improve the code-coverage. - Add tests for XDP tail adjustment in AF_XDP. New hardware / drivers: - OpenVPN virtual driver: offload OpenVPN data channels processing to the kernel-space, increasing the data transfer throughput WRT the user-space implementation. - Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC. - Broadcom asp-v3.0 ethernet driver. - AMD Renoir ethernet device. - ReakTek MT9888 2.5G ethernet PHY driver. - Aeonsemi 10G C45 PHYs driver.
