efi_loader: efi_console: support editable input fields

2025-10-26T10:15:21+00:00

When editing eficonfig "optional data" (typically cmdline arguments)
it's useful to be able to edit the string rather than having to re-type
the entire thing. Implement support for editing buffers to make this a
whole lot nicer. Specifically, add support for moving the cursor with
the arrow keys and End key as well as deleting backwards with the delete
key.

efi_loader: Use ESRT_FW_TYPE_SYSTEMFIRMWARE instead of ESRT_FW_TYPE_UNKNOWN

2025-10-18T09:52:28+00:00

We currently set the firmware image type to ESRT_FW_TYPE_UNKNOWN.

The spec defines the following:
ESRT_FW_TYPE_UNKNOWN 0x00000000
ESRT_FW_TYPE_SYSTEMFIRMWARE 0x00000001
ESRT_FW_TYPE_DEVICEFIRMWARE 0x00000002
ESRT_FW_TYPE_UEFIDRIVER 0x00000003

Since we don't support updating DEVICEFIRMWARE or UEFIDRIVER types,
let's switch over to SYSTEMFIRMWARE which seems more appropriate.

efi_loader: correctly check if the HTTP protocol is found

2025-10-18T09:41:32+00:00

In function efi_http_service_binding_destroy_child() phandler is created as
as a local variable. If efi_search_protocol() fails, phandler will hold a
random value from the stack. Even it is not zero, we must not use it.

If efi_search_protocol() succeeds, the pointer has already be dereferenced,
so checking against NULL makes not sense here.

If ChildHandle is not a valid UEFI handle, we must return
EFI_INVALID_PARAMETER.

Use a single location for EFI_EXIT().

efi_loader: Prevent leak of memory from tmp_files

2025-10-18T09:41:31+00:00

After the malloc of tmp_files and before its value is recorded an early
exit will need to free tmp_files to prevent leaking that memory.

efi_loader: Improve disk image detection in efi_bootmgr

2025-10-14T07:30:56+00:00

Enhances the process for identifying disk images within the EFI boot
manager. Utilize part_driver_lookup_type() to verify the validity of a
downloaded file as a disk image, rather than depending on file
extensions.

part_driver_lookup_type() is now used in the prepare_loaded_image()
function in the EFI boot manager to detect partitions on a block device
created from a downloaded image. This allows the boot manager to boot
from any disk image that can be recognized by a partition driver, not
just ISO and IMG images.

Update prepare_loaded_image() to create the ramdisk block device
internally, obtain the blk_desc and use part_driver_lookup_type() to
detect a valid partition table.

In try_load_from_uri_path(), try prepare_loaded_image() first to detect
disk images, and fall back to PE-COFF detection only if that fails.

efi_loader: Cleanup UEFI Variables menu selection

2025-09-27T07:22:00+00:00

There are 3 options listed between choice/endchoice FILE/TEE/NO_STORE.
There is no reason to add other config with dependencies between
choice/endchoice because they can never be selected because they depends on
only that 3 options which can be selected.
That's why move additional configuration with dependency below choice
section.

When doing compile testing build we cannot rely on having a valid file
for EFI_VAR_SEED_FILE to exist, so disable this option when doing
