- The ExtractSection() function processes the input section and

- contents. If the section being extracted contains
- authentication information (the section's
- GuidedSectionHeader.Attributes field has the
- EFI_GUIDED_SECTION_AUTH_STATUS_VALID bit set), the values
- returned in AuthenticationStatus must reflect the results of
- the authentication operation. Depending on the algorithm and
- size of the encapsulated data, the time that is required to do
- a full authentication may be prohibitively long for some
- classes of systems. To indicate this, use
- EFI_SECURITY_POLICY_PROTOCOL_GUID, which may be published by
- the security policy driver (see the Platform Initialization
- Driver Execution Environment Core Interface Specification for
- more details and the GUID definition). If the
- EFI_SECURITY_POLICY_PROTOCOL_GUID exists in the handle
- database, then, if possible, full authentication should be
- skipped and the section contents simply returned in the
- OutputBuffer. In this case, the
- EFI_AUTH_STATUS_PLATFORM_OVERRIDE bit AuthenticationStatus
- must be set on return. ExtractSection() is callable only from
- TPL_NOTIFY and below. Behavior of ExtractSection() at any
- EFI_TPL above TPL_NOTIFY is undefined. Type EFI_TPL is
- defined in RaiseTPL() in the UEFI 2.0 specification.
