The EFI_SECURITY_ARCH_PROTOCOL (SAP) is used to abstract platform-specific
|
|
policy from the DXE core response to an attempt to use a file that returns a
|
|
given status for the authentication check from the section extraction protocol.
|
|
|
|
The possible responses in a given SAP implementation may include locking
|
|
flash upon failure to authenticate, attestation logging for all signed drivers,
|
|
and other exception operations. The File parameter allows for possible logging
|
|
within the SAP of the driver.
|
|
|
|
If File is NULL, then EFI_INVALID_PARAMETER is returned.
|
|
|
|
If the file specified by File with an authentication status specified by
|
|
AuthenticationStatus is safe for the DXE Core to use, then EFI_SUCCESS is returned.
|
|
|
|
If the file specified by File with an authentication status specified by
|
|
AuthenticationStatus is not safe for the DXE Core to use under any circumstances,
|
|
then EFI_ACCESS_DENIED is returned.
|
|
|
|
If the file specified by File with an authentication status specified by
|
|
AuthenticationStatus is not safe for the DXE Core to use right now, but it
|
|
might be possible to use it at a future time, then EFI_SECURITY_VIOLATION is
|
|
returned.
|
|
|
|
@param This The EFI_SECURITY_ARCH_PROTOCOL instance.
|
|
@param AuthenticationStatus
|
|
This is the authentication type returned from the Section
|
|
Extraction protocol. See the Section Extraction Protocol
|
|
Specification for details on this type.
|
|
@param File This is a pointer to the device path of the file that is
|
|
being dispatched. This will optionally be used for logging.
|
|
|
|
@retval EFI_SUCCESS Do nothing and return.
|
|
@retval EFI_INVALID_PARAMETER File is NULL.
