efi: Use the correct GUID for the SMBIOS table

2024-01-07T20:45:07+00:00

EFI does not use the 'anchor string' to determine the SMBIOS table
version, instead preferring to have two separate GUIDs. Use the correct
one, depending on the table version.

Call unmap_system() to balance to the use of map_sysmem()

efi_loader: add return to efibootmgr event group

2023-11-18T08:08:09+00:00

When the image loaded by efibootmgr returns, efibootmgr
needs to clean the resources. Adding the event of returning
to efibootmgr is useful to simplify the implementation.

efi_loader: add missing const classifier for event service

2023-11-18T08:08:09+00:00

const classifier is missing in EventGroup parameter of
CreateEventEx(). Fix it to remove the compiler warning.

NotifyContext parameter of CreateEventEx() is also defined
with const in UEFI specification, but NotifyContext parameter
of CreateEvent() is defined without const.
Since current implementation calls the common efi_create_event()
function from both CreateEventEx() and CreateEvent() services,
NotifyContext parameter leaves as is.

efi_loader: support all uclasses in device path

2023-07-20T07:12:50+00:00

On devices with multiple USB mass storage devices errors like

    Path /../USB(0x0,0x0)/USB(0x1,0x0)/Ctrl(0x0)
    already installed.

are seen. This is due to creating non-unique device paths. To uniquely
identify devices we must provide path nodes for all devices on the path
from the root device.

Add support for generating device path nodes for all uclasses.

efi_loader: Fix warnings for unaligned accesses

2023-05-13T09:09:51+00:00

Tom reports that when building with clang we see this warning:
field guid within 'struct efi_hii_keyboard_layout' is less aligned than 'efi_guid_t' and is usually due to 'struct efi_hii_keyboard_layout' being packed, which can lead to unaligned accesses [-Wunaligned-access]

This happens because 'struct efi_hii_keyboard_layout' is defined as
packed and thus has 1-byte alignment but efi_guid_t is a type that
requires greater alignment than that.

However the EFI spec describes the EFI_GUID as
"128-bit buffer containing a unique identifier value.
Unless otherwise specified"

So convert the efi_guid_t -> u8 b[16] here and skip the alignment
requirements.  Since the struct is packed to begin with, it makes no
difference on the final memory layout.

efi_loader: Fix flexible array member definitions

2023-04-21T06:50:35+00:00

When a structure contains a flexible array member, it is not supposed to be
included in arrays or other structs.
Quoting the C spec [0]
"Such a structure (and any union containing, possibly recursively, a
member that is such a structure) shall not be a member of a structure
or an element of an array."

IOW efi_hii_keyboard_layout should not include
struct efi_key_descriptor descriptors[]; since we use it at the
declaration of struct efi_hii_keyboard_package.

efi_loader: correct shortening of device-paths

2023-04-01T08:11:50+00:00

We use short device-paths in boot options so that a file on a block device
can be found independent of the port into which the device is plugged.

Usb() device-path nodes only contain port and interface information and
therefore cannot identify a block device.
UsbWwi() device-path nodes contain the serial number of USB devices.
