Pull request for UEFI sub-system for efi-2021-01-rc3 (3)

The following errors are corrected:

* Linux crash when accessing UEFI variables at runtime.
* UEFI variable using standalone MM on 32 bit systems
  not working due to missing packing of communication
  structure
* NULL dereference when FAT16 root directory is full
* FAT files with a short file name starting with 0xE5 (0x05 in directory
  entry) where treated as deleted.

The UEFI SetTime() service is enabled on ARM QEMU.

charset: make u16_strnlen accessible at runtime

2020-11-29T04:18:37+00:00

commit 1fabfeef506c ("efi_loader: parameter check in GetNextVariableName()")
introduces a check using u16_strnlen(). This code is used on EFI
runtime variables as well, so unless we mark it as runtime, the kernel
will crash trying to access it.

lib/efi_loader: fix ABI in efi_mm_communicate_header

2020-11-29T04:18:37+00:00

Pack struct efi_mm_communicate_header as done in EDK2 as seen in
release 201808 [1]. If not packed sizeof() for the structure adds
4 additional bytes on 32bit targets which breaks the ABI.

fs: fat: use ATTR_ARCH instead of anonymous 0x20

2020-11-29T04:18:16+00:00

Using constants instead of anonymous numbers increases code readability.

fs: fat: directory entries starting with 0x05

2020-11-29T04:18:16+00:00

0x05 is used as replacement letter for 0xe5 at the first position of short
file names. We must not skip over directory entries starting with 0x05.

fs: fat: avoid NULL dereference when root dir is full

2020-11-29T04:18:16+00:00

When trying to create a file in the full root directory of a FAT32
filesystem a NULL dereference can be observed.

When the root directory of a FAT16 filesystem is full fill_dir_slot() must
return -1 to signal that a new directory entry could not be allocated.
