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// NOTE: netd doesn't enforce any semantics for the permission values. E.g., while all apps with
28// CONNECTIVITY_INTERNAL may also implicitly or explicitly have CHANGE_NETWORK_STATE, netd doesn't
29// enforce it. It's the responsibility of the caller to set all permissions bits explicitly. I.e.,
30// if you set the PERMISSION_CONNECTIVITY_INTERNAL bit, you should probably also set the
31// PERMISSION_CHANGE_NETWORK_STATE bit.
