Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.

Pull landlock updates from Mickaël Salaün: "This brings two main changes to Landlock: - A signal scoping fix with a new interface for user space to know if it is compatible with the running kernel. - Audit support to give visibility on why access requests are denied, including the origin of the security policy, missing access rights, and description of object(s). This was designed to limit log spam as much as possible while still alerting about unexpected blocked access. With these changes come new and improved documentation, and a lot of new tests" * tag 'landlock-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: (36 commits) landlock: Add audit documentation selftests/landlock: Add audit tests for network selftests/landlock: Add audit tests for filesystem selftests/landlock: Add audit tests for abstract UNIX socket scoping selftests/landlock: Add audit tests for ptrace selftests/landlock: Test audit with restrict flags selftests/landlock: Add tests for audit flags and domain IDs selftests/landlock: Extend tests for landlock_restrict_self(2)'s flags selftests/landlock: Add test for invalid ruleset file descriptor samples/landlock: Enable users to log sandbox denials landlock: Add LANDLOCK_RESTRICT_SELF_LOG_SUBDOMAINS_OFF landlock: Add LANDLOCK_RESTRICT_SELF_LOG_*_EXEC_* flags landlock: Log scoped denials landlock: Log TCP bind and connect denials landlock: Log truncate and IOCTL denials landlock: Factor out IOCTL hooks landlock: Log file-related denials landlock: Log mount-related denials landlock: Add AUDIT_LANDLOCK_DOMAIN and log domain status landlock: Add AUDIT_LANDLOCK_ACCESS and log ptrace denials ...
