Re-implemented SP800Derive in C++, which is added as the new key derivation function in Android 9.0 May update. From file services/core/java/com/android/server/locksettings/SP800Derive.java in frameworks/base.

2018-01-04Add spblob decrypt for secdis method (Pixel 1 non-weaver)Ethan Yonker1-64/+222
Support decrypting Pixel 1 devices using secdis method with the gatekeeper instead of weaver. Add a bit of a dirty workaround to a permissions issue that the keystore presents because the keystore checks the uid of the calling process and refuses to let the root user add authorization tokens. We write the auth token to a file and start a separate service that runs under the system user. The service reads the token from the file and adds it to the keystore. You must define this service in your init.recovery.{hardware}.rc file: service keystore_auth /sbin/keystore_auth disabled oneshot user system group root seclabel u:r:recovery:s0 TWRP will run this service when needed.
