-Subject: [PATCH] KeyStore: Block key attestation for Google Play Services
-
-In order to enforce SafetyNet security, Google Play Services is now
-using hardware attestation for ctsProfile validation in all cases, even
-when basic attestation is selected. The SafetyNet API response from GMS
-will report that basic attestation was used, but under the hood,
-hardware attestation is always used regardless of the reported state.
-This results in SafetyNet failing to pass due to TrustZone reporting an
-unlocked bootloader (and a partially invalidated root of trust) in the
-key attestation result.
-
-We can still take advantage of the fact that this usage of hardware
-attestation is opportunistic - that is, it falls back to basic
-attestation if key attestation fails to run - and prevent GMS from using
-key attestation at the framework level. This causes it to gracefully
-fall back to basic attestation and pass SafetyNet with an unlocked
-bootloader.
-
-Key attestation is still available for other apps, as there are valid
-uses for it that do not involve SafetyNet.
-
-The "not implemented" error code from keymaster is used to simulate the
-most realistic failure condition to evade detection, i.e. an old device
-that lacks support for key attestation.
