Images with an anti-rollback counter value "arbvn" declared in the FDT will be compared against the current device anti-rollback counter value, and older images will not pass signature validation. If the image is newer, the device anti-rollback counter value will be updated. The "arbvn" value is stored/retrieved using the newly added security driver. A "TPM backed" and "sandbox backed" security driver have been provided as examples. Adds new configs: - CONFIG_DM_SECURITY : enable security device support - CONFIG_SECURITY_SANDBOX : enables "sandbox_security" driver - CONFIG_SECURITY_TPM : Enables "tpm_security" driver - CONFIG_ARBP : enable enforcement of OS anti-rollback counter during image loading - CONFIG_FIT_ARBVP_GRACE : adds a one unit grace period to OS anti-rollback protection Sean Edmond (1): dm: test: Add a test for security driver Stephen Carlson (4): drivers: security: Add security devices to driver model drivers: security: Add TPM2 implementation of security devices common: Add OS anti-rollback validation using security devices common: Add OS anti-rollback grace period MAINTAINERS | 9 ++ arch/sandbox/dts/test.dts | 8 ++ boot/Kconfig | 19 +++ boot/image-fit-sig.c | 94 +++++++++++++++ boot/image-fit.c | 23 ++++ configs/sandbox_defconfig | 3 + drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/security/Kconfig | 25 ++++ drivers/security/Makefile | 7 ++ drivers/security/sandbox_security.c | 65 +++++++++++ drivers/security/security-tpm.c | 173 ++++++++++++++++++++++++++++ drivers/security/security-uclass.c | 30 +++++ include/dm-security.h | 44 +++++++ include/dm/uclass-id.h | 1 + include/image.h | 4 + include/tpm-v2.h | 1 + test/dm/Makefile | 1 + test/dm/security.c | 78 +++++++++++++ 19 files changed, 588 insertions(+) create mode 100644 drivers/security/Kconfig create mode 100644 drivers/security/Makefile create mode 100644 drivers/security/sandbox_security.c create mode 100644 drivers/security/security-tpm.c create mode 100644 drivers/security/security-uclass.c create mode 100644 include/dm-security.h create mode 100644 test/dm/security.c -- 2.40.0
