2025-07-29kstack_erase: Fix missed export of renamed KSTACK_ERASE_CFLAGSKees Cook1-1/+1
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).

These are the first KUnit tests for lib/crypto/. So in addition to being useful tests for these specific algorithms, they also establish some conventions for lib/crypto/ testing going forwards. The new tests are fairly comprehensive: more comprehensive than the generic crypto infrastructure's tests. They use a variety of techniques to check for the types of implementation bugs that tend to occur in the real world, rather than just naively checking some test vectors.

2025-07-28Merge tag 'vfs-6.17-rc1.fileattr' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsLinus Torvalds1-0/+2
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

2025-07-26scripts: add zboot support to extract-vmlinuxJeremy Linton1-7/+6
Zboot compressed kernel images are used for arm64 kernels on various distros. extract-vmlinux fails with those kernels because the wrapped image is another PE. While this could be a bit confusing, the tools primary purpose of unwrapping and decompressing the contained kernel image makes it the obvious place for this functionality. Add a 'file' check in check_vmlinux() that detects a contained PE image before trying readelf. Recent (FILES_39, Jun/2020) file implementations output something like: "Linux kernel ARM64 boot executable Image, little-endian, 4K pages" Which is also a stronger statement than readelf provides so drop that part of the comment. At the same time this means that kernel images which don't appear to contain a compressed image will be returned rather than reporting an error. Which matches the behavior for existing ELF files. The extracted PE image can then be inspected, or used as would any other kernel PE. Signed-off-by: Jeremy Linton <jeremy.linton@arm.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2025-07-22tracing: Remove redundant config HAVE_FTRACE_MCOUNT_RECORDSteven Rostedt1-1/+1
Ftrace is tightly coupled with architecture specific code because it requires the use of trampolines written in assembly. This means that when a new feature or optimization is made, it must be done for all architectures. To simplify the approach, CONFIG_HAVE_FTRACE_* configs are added to denote which architecture has the new enhancement so that other architectures can still function until they too have been updated. The CONFIG_HAVE_FTRACE_MCOUNT was added to help simplify the DYNAMIC_FTRACE work, but now every architecture that implements DYNAMIC_FTRACE also has HAVE_FTRACE_MCOUNT set too, making it redundant with the HAVE_DYNAMIC_FTRACE. Remove the HAVE_FTRACE_MCOUNT config and use DYNAMIC_FTRACE directly where applicable.

2025-07-21stackleak: Rename stackleak_track_stack to __sanitizer_cov_stack_depthKees Cook1-26/+26
The Clang stack depth tracking implementation has a fixed name for the stack depth tracking callback, "__sanitizer_cov_stack_depth", so rename the GCC plugin function to match since the plugin has no external dependencies on naming.

2025-07-21stackleak: Rename STACKLEAK to KSTACK_ERASEKees Cook1-3/+3
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.

2025-07-17docs: kernel-doc: emit warnings for ancient versions of PythonMauro Carvalho Chehab1-0/+10
Kernel-doc requires at least version 3.6 to run, as it uses f-string. Yet, Kernel build currently calls kernel-doc with -none on some places. Better not to bail out when older versions are found. Versions of Python prior to 3.7 do not guarantee to remember the insertion order of dicts; since kernel-doc depends on that guarantee, running with such older versions could result in output with reordered sections. Check Python version when called via command line.

2025-07-15Merge branch 'kdoc-item2' into docs-mwJonathan Corbet4-244/+145
The kerneldoc parsing phase gathers all of the information about the declarations of interest, then passes it through to the output phase as a dict that is an unstructured blob of information; this organization has its origins in the Perl version of the program. It results in an interface that is difficult to reason about, dozen-parameter function calls, and other ills. Introduce a new class (KdocItem) to carry this information between the parser and the output modules, and, step by step, modify the system to use this class in a more structured way. This could be taken further by creating a subclass of KdocItem for each declaration type (function, struct, ...), but that is probably more structure than we need. The result is (I hope) clearer code, the removal of a bunch of boilerplate, and no changes to the generated output.
