Following are currently world readable but their scope

Files labelled with 'same_process_hal_file' are allowed to be

Wifi Keystore HAL is a HwBinder service (currently offered by keystore
daemon) which is used by Wifi Supplicant HAL. This commit thus
switches the SELinux policy of Wifi Keystore HAL to the approach used
for non-HAL HwBinder services.

The basic idea is simimilar to how we express Binder services in the
policy, with two tweaks: (1) we don't have 'hwservicemanager find' and
thus there's no add_hwservice macro, and (2) we need loosen the
coupling between core and vendor components. For example, it should be
possible to move a HwBinder service offered by a core component into
another core component, without having to update the SELinux policy of
the vendor image. We thus annotate all components offering HwBinder
service x across the core-vendor boundary with x_server, which enables
the policy of clients to contain rules of the form:
binder_call(mydomain, x_server), and, if the service uses IPC
callbacks, also binder_call(x_server, mydomain).

"tee" domain is a vendor domain. Hence its rules should live on the
vendor image.

What's left as public API is that:
1. tee domain exists and that it is permitted to sys_rawio capability,
2. tee_device type exists and apps are not permitted to access
   character devices labeled tee_device.

If you were relying on system/sepolicy automatically labeling
/dev/tf_driver as tee_device or labeling /system/bin/tf_daemon as
tee_exec, then you need to add these rules to your device-specific
file_contexts.
