customizable_types — The SELinux customizable types configuration file
Description
The customizable_types file contains a list of types that can be customised in some way by SELinux-aware applications.
Generally this is a file context type that is usually set on files that need to be shared among certain domains and where the administrator wants to manually manage the type.
The use of customizable types is deprecated as the preferred approach is to use semanage(8) fcontext(8) ...(8). However, SELinux-aware applications such as setfiles(8) will use this information to obtain a list of types relating to files that should not be relabeled.
selinux_customizable_types_path(3) will return the active policy path to this file. The default customizable types file is:
/etc/selinux/{SELINUXTYPE}/contexts/customizable_types
Where {SELINUXTYPE} is the entry from the selinux configuration file config (see selinux_config(5)).
is_context_customizable(3) reads this file to determine if a context is customisable or not for the active policy.
File Format
Each line in the file consists of the following:
type
Where:
- type
The type defined in the policy that can be customised.
Example
# ./contexts/customizable_types
mount_loopback_t
public_content_rw_t
public_content_t
swapfile_t
sysadm_untrusted_content_t
