// Convenience structure types for constructing "signature lists" for
|
|
// authenticated UEFI variables.
|
|
//
|
|
// The most important thing about the variable payload is that it is a list of
|
|
// lists, where the element size of any given *inner* list is constant.
|
|
//
|
|
// Since X509 certificates vary in size, each of our *inner* lists will contain
|
|
// one element only (one X.509 certificate). This is explicitly mentioned in
|
|
// the UEFI specification, in "28.4.1 Signature Database", in a Note.
|
|
//
|
|
// The list structure looks as follows:
|
|
//
|
|
// struct EFI_VARIABLE_AUTHENTICATION_2 { |
|
|
// struct EFI_TIME { |
|
|
// UINT16 Year; |

// EFI_GUID SignatureType; | | |
|

// UINT32 SignatureListSize; -------------------------+ | |

// introduced the flexible array member), and because subtracting those pesky

// sizes of 1 is annoying, and because the format is fully specified in the
|
|
// UEFI specification, we'll introduce two matching convenience structures that
|
|
// are customized for our X.509 purposes.
