SecurityPkg/DxeImageVerificationLib: Check result of GetEfiGlobalVariable2
|
||||
|
||||
Call gRT->GetVariable() directly to read the SecureBoot variable. It is
|
||||
one byte in size so we can easily place it on the stack instead of
|
||||
having GetEfiGlobalVariable2() allocate it for us, which avoids a few
|
||||
possible error cases.
|
||||
|
||||
Skip secure boot checks if (and only if):
|
||||
|
||||
(a) the SecureBoot variable is not present (EFI_NOT_FOUND) according to
|
||||
the return value, or
|
||||
(b) the SecureBoot variable was read successfully and is set to
|
||||
SECURE_BOOT_MODE_DISABLE.
|
||||
|
||||
Previously the code skipped the secure boot checks on *any*
|
||||
gRT->GetVariable() error (GetEfiGlobalVariable2 sets the variable
|
||||
value to NULL in that case) and also on memory allocation failures.
