* Move package verifier from libinstall to libotautilJacky Liu2021-12-221-1/+1

* Add a fuzzer for OTA package verificationWill Coster2020-11-101-0/+37
This is a pretty simplistic approach, it just shoves random data at the verifier. The OTA format isn't too complicated so this should hopefully be sufficient to let the fuzzer exercise the potentially interesting parsing code. Test: Let the fuzzer run on device for awhile: 1) FUZZ=libinstall_verify_package_fuzzer 2) SANITIZE_TARGET=hwaddress make ${FUZZ} 3) cd ${ANDROID_PRODUCT_OUT} && adb root && adb sync data 4) adb shell /data/fuzz/arm64/${FUZZ}/${FUZZ} Change-Id: Icac6bde017b497d9f92c06191eb29e107ba9c0a7
