Pull selinux updates from Paul Moore: - Add additional SELinux access controls for kernel file reads/loads The SELinux kernel file read/load access controls were never updated beyond the initial kernel module support, this pull request adds support for firmware, kexec, policies, and x.509 certificates. - Add support for wildcards in network interface names There are a number of userspace tools which auto-generate network interface names using some pattern of <XXXX>-<NN> where <XXXX> is a fixed string, e.g. "podman", and <NN> is a increasing counter. Supporting wildcards in the SELinux policy for network interfaces simplifies the policy associted with these interfaces. - Fix a potential problem in the kernel read file SELinux code SELinux should always check the file label in the security_kernel_read_file() LSM hook, regardless of if the file is being read in chunks. Unfortunately, the existing code only considered the file label on the first chunk; this pull request fixes this problem. There is more detail in the individual commit, but thankfully the existing code didn't expose a bug due to multi-stage reads only taking place in one driver, and that driver loading a file type that isn't targeted by the SELinux policy. - Fix the subshell error handling in the example policy loader Minor fix to SELinux example policy loader in scripts/selinux due to an undesired interaction with subshells and errexit. * tag 'selinux-pr-20250323' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: get netif_wildcard policycap from policy instead of cache selinux: support wildcard network interface names selinux: Chain up tool resolving errors in install_policy.sh selinux: add permission checks for loading other kinds of kernel files selinux: always check the file label in selinux_kernel_read_file() selinux: fix spelling error
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.
