20// This enum represents the permissions we care about for networking. When applied to an app, it's
21// the permission the app (UID) has been granted. When applied to a network, it's the permission an
22// app must hold to be allowed to use the network. PERMISSION_NONE means "no special permission is
23// held by the app" or "no special permission is required to use the network".
24//
25// Permissions are flags that can be OR'ed together to represent combinations of permissions.
26//
27// PERMISSION_NONE is used for regular networks and apps, such as those that hold the
28// android.permission.INTERNET framework permission.
29//
30// PERMISSION_NETWORK is used for privileged networks and apps that can manipulate or access them,
31// such as those that hold the android.permission.CHANGE_NETWORK_STATE framework permission.
32//
33// PERMISSION_SYSTEM is used for system apps, such as those that are installed on the system
34// partition, those that hold the android.permission.CONNECTIVITY_INTERNAL framework permission and
35// those whose UID is less than FIRST_APPLICATION_UID.
