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.
