Module selabel 

SELinux security context labeling for filesystem trees.

This module implements SELinux policy parsing and file labeling functionality. It reads SELinux policy files (file_contexts, file_contexts.subs, etc.) and applies appropriate security.selinux extended attributes to filesystem nodes. The implementation uses pcre2 for compatibility with selinux regex (same library selinux uses)
