Currently, NetworkCapabilities always redacts the TransportInfo
objects it contains whenever a defensive copy is made. This makes
it impossible to make a defensive copy on a TransportInfo
parcelled from another process without redacting it.
Stop redacting by default; instead rely on ConnectivityService
explicitly calling NetworkCapabilities' redacting constructor
when it returns a NetworkCapabilities object to an app via a
callback or synchronous call. This is currently done by
- createWithLocationInfoSanitizedIfNecessaryWhenParceled, which
is called from callCallbackForRequest, getNetworkCapabilities,
and getDefaultNetworkCapabilitiesForUser.
- getNetworkCapabilitiesWithoutUids, which is used when sending
ConnectivityDiagnosticsManager callbacks. In this method,
unconditionally redact all information, which is what the code
did previously due to the default redaction setting for empty
NetworkCapabilities objects being REDACT_ALL.
