efi_loader: variable: attributes may not be changed if a variable exists

2019-05-24T16:58:14+00:00

If a variable already exists, efi_set_variable() should not change
the variable's attributes. This patch enforces it.

efi_loader: variable: return error for APPEND_WRITE

2019-05-24T16:58:14+00:00

The current efi_st_variable() doesn't support EFI_VARIABLE_APPEND_WRITE
attiribute for now, and so should return an error.

efi_loader: GetVariable set attributes for EFI_BUFFER_TOO_SMALL

2019-05-19T06:10:10+00:00

UEFI spec 2.7 erratum A leaves it undefined if Attributes should be set if
GetVariable() returns EFI_BUFFER_TOO_SMALL.

UEFI spec 2.8 defines that Attributes should be set if the return value is
either EFI_SUCCESS or EFI_BUFFER_TOO_SMALL.

Set Attributes if the return value is EFI_BUFFER_TOO_SMALL.

efi_loader: EFI_PRINT instead of debug for variable services

2019-04-07T12:17:06+00:00

For debug messages inside EFI API functions we should use the EFI_PRINT
macro which gives us well aligned output like:

EFI: Entry efi_get_variable("PlatformLang" ...)
  EFI: get 'efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_PlatformLang'
EFI: Exit: efi_get_variable: 14

efi_loader: fix GetNextVariableName

2019-02-13T08:40:06+00:00

Our current implementation of GetNextVariableName() first collects all EFI
variables. If none is found at all hexport_r() returns a zero length string
terminated by \0 and the value 1 as number of bytes in the returned buffer.

In this case GetNextVariableName() has to return EFI_NOT_FOUND.

efi_loader: implement GetNextVariableName()

2019-02-13T08:40:06+00:00

The current GetNextVariableName() is a placeholder.
With this patch, it works well as expected.
