cmd/efidebug: missing initialization of load_options

2020-08-13T20:37:36+00:00

Variable load_options must be initialized to NULL to avoid a segmentation
fault when freeing the memory this variable points to.

efi_loader: set load options in boot manager

2020-08-08T17:03:24+00:00

Up to now we used the value of the bootargs environment variable as load
options in the boot manager. This is not correct. The data has to be taken
from the Boot#### variable.

Let the boot manager copy the optional data of the EFI_LOAD_OPTION as load
options to the loaded image protocol.

efi_loader: validate load option

2020-06-03T15:19:17+00:00

For passing the optional data of the load option to the loaded imaged
protocol we need its size.

efi_deserialize_load_option() is changed to return the size of the optional
data.

As a by-product we get a partial validation of the load option.
Checking the length of the device path remains to be implemented.

Some Coverity defects identified the load options as user input because
get_unaligned_le32() and get_unaligned_le16() is called. But non of these
Coverity defects can be resolved without marking functions with Coverity
specific tags.

The UEFI 2.8 specification has introduced the EFI_MEMORY_SP memory
attribute. Add it to the 'efidebug memmap' and 'efi mem' commands.

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55+00:00

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

cmd: efidebug: Add support for querying UEFI variable storage

2020-05-17T19:59:53+00:00

With the previous patches that use OP-TEE and StandAloneMM for UEFI
variable storage we've added functionality for efi_query_variable_info.
So let's add the relevant command to efidebug and retrieve information
about the container used to store UEFI variables

cmd: efidebug: fix -Werror=type-limits warning

2020-05-09T22:01:12+00:00

Compiling with -Wtype-limits yields:

cmd/efidebug.c:968:32: error: comparison is always false due to limited
range of data type [-Werror=type-limits]
  968 |  if (*endp != '\0' || bootnext > 0xffff) {
      |

Remove the superfluous check.

The check here, "Null pointer dereferences," is a false positive.
So leave a comment.
