- Use the tarball provided by upstream developers instead of the one
generated by Github. Indeed
https://github.com/rhboot/shim/releases/tag/15.4 indicates "As
usual, please use the shim-15.4.tar.bz2 tarball, rather than the
other two archives github automatically produces."
- The tarball now includes the gnu-efi code, so we no longer need to
select gnu-efi and have it as a build dependency. We continue to use
BR2_PACKAGE_GNU_EFI_ARCH_SUPPORTS as we still only build for those
architectures that have gnu-efi support. We also drop the
EFI_INCLUDE, EFI_PATH and LIBDIR variables, as gnu-efi no longer
needs to be searched in STAGING_DIR.

CVE-2020-14372 grub2: The acpi command allows privileged user to load crafted
ACPI tables when Secure Boot is enabled
CWE-184
7.5/CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H
GRUB2 enables the use of the command acpi even when Secure Boot is signaled by
the firmware. An attacker with local root privileges to can drop a small SSDT
in /boot/efi and modify grub.cfg to instruct grub to load said SSDT. The SSDT
then gets run by the kernel and it overwrites the kernel lock down configuration
enabling the attacker to load unsigned kernel modules and kexec unsigned code.

CWE-416
7.5/CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H
The rmmod implementation for GRUB2 is flawed, allowing an attacker to unload
a module used as dependency without checking if any other dependent module is
still loaded. This leads to an use-after-free scenario possibly allowing an
attacker to execute arbitrary code and by-pass Secure Boot protections.

CWE-787
6.9/CVSS:3.1/AV:P/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H
grub_usb_device_initialize() is called to handle USB device initialization. It
reads out the descriptors it needs from the USB device and uses that data to
fill in some USB data structures. grub_usb_device_initialize() performs very
little bounds checking and simply assumes the USB device provides sane values.
This behavior can trigger memory corruption. If properly exploited, this would
lead to arbitrary code execution allowing the attacker to by-pass Secure Boot
mechanism.

grub_parser_split_cmdline() expands variable names present in the supplied
command line in to their corresponding variable contents and uses a 1kB stack
buffer for temporary storage without sufficient bounds checking. If the
function is called with a command line that references a variable with a
sufficiently large payload, it is possible to overflow the stack buffer,
corrupt the stack frame and control execution. An attacker may use this to
circumvent Secure Boot protections.

package version and the file extension.
Commit c043ecb20 (support/download: change format of archives generated
from svn) did so for archives generated from a subversion checkout.
However, for a few packages, we manually force the _SOURCE variable,
because we want to share the archive with another package, to avoid
downloading and storing those archives twice. This is the case for:
- linux-headers and linux
- barebox-aux and barebox
When the generated tarballs were renamed with the aforementioned

Switch to using the tarball helper, that can generate reproducible
archives whatever the tar version >= 1.27.
However, those archives are not identical to the previous ones generated
in the (now-broken) gnu format.
To avoid any clashing between old and new archives, and new and old
Buildroot versions, we need to name the new generated archives
differently from the existing ones.
So, we bump the git-specific format-version to -br1.
The %ci date has been supported by git back to 1.6.0, released August
2008); it is not strictly ISO8601, but is still accepted as a PAX date
header. The strict ISO8601 placeholder, %cI, was only introduced with
2.2.0, release in November 2014, so too recent to be widely available.
As the format and the names of the archives changes, we need to update
all the hash files with the new names and hashes.
Of all the bootloaders that have a git download method, vexpress-firmware
is the only one to have a hash. Others have no hash files, or they have
explicitly set BR_NO_CHECK_HASH_FOR.
For the packages, linux-headers is the special snowflake, as the git
download is only for custom git tree, so it is excluded from the hash
verification with BR_NO_CHECK_HASH_FOR.

TF-A supports stack smashing protection (-fstack-protector-*).
However, that feature is currently silently disabled because
ENABLE_STACK_PROTECTOR is not set during build time.
As documented in the TF-A user guide, the flag ENABLE_STACK_PROTECTOR
is required to enable stack protection support. When enabled the symbols
for the stack protector (e.g. __stack_chk_guard) are built.
This needs to be done because TF-A does not link against an external
library that provides that symbols (e.g. libc).
So in case we see that BR2_SSP_* is enabled, let's enable the corresponding
ENABLE_STACK_PROTECTOR build flag for TF-A as documented in the TF-A user guide.
This patch also fixes a the following linker errors with older TF-A versions
if BR2_SSP_* is enabled (i.e. -fstack-protector-* is used as compiler flag)
and ENABLE_STACK_PROTECTOR is not set, which are caused by the missing
stack protector symbols:
[...]
params_setup.c:(.text.params_early_setup+0xc): undefined reference to `__stack_chk_guard'
aarch64-none-linux-gnu-ld: params_setup.c:(.text.params_early_setup+0x14): undefined reference to `__stack_chk_guard'
aarch64-none-linux-gnu-ld: params_setup.c:(.text.params_early_setup+0x104): undefined reference to `__stack_chk_guard'

pmu.c:(.text.rockchip_soc_sys_pwr_dm_suspend+0xc): undefined reference to `__stack_chk_guard'
[...]
TF-A releases after Nov 2019, that include 7af195e29a4, will circumvent
these issue by explicitliy and silently disabling the stack protector
by appending '-fno-stack-protector' to the compiler flags in case
ENABLE_STACK_PROTECTOR is not set.

Migrating the support for this feature to uboot-tools to gain the

When _ENVIMAGE_SOURCE is not set, we generate a default environment.
However, this default depends on the U-Boot configuration. Therefore,
this can only be done if uboot itself is built as well, and
host-uboot-tools needs to depend on uboot.
For the same reason, the commands for creating the environment have to
be adapted a little. Take this occasion to drastically simplify them.
Note: This patch creates a circular dependency with uboot until the
similar migration patch is merged for uboot scripts

The buildroot custom bareboxenv compile command misses the additional
include path 'scripts/include' to gain access to the local copy of the
kernel header files (which leads to compile error when using an older
toolchain).
This could be fixed by enhancing the custom bareboxenv compile command
(see [1]) or by using the barebox build system by simply enabling the
CONFIG_BAREBOXENV_TARGET option (available since April 2012, see [2])
instead (as suggested by Yann E. MORIN).

Fixes the following security issues:
* CVE-2020-10713
A flaw was found in grub2, prior to version 2.06. An attacker may
use the GRUB 2 flaw to hijack and tamper the GRUB verification
process. This flaw also allows the bypass of Secure Boot
protections. In order to load an untrusted or modified kernel, an
attacker would first need to establish access to the system such as
gaining physical access, obtain the ability to alter a pxe-boot
network, or have remote access to a networked system with root
access. With this access, an attacker could then craft a string to
cause a buffer overflow by injecting a malicious payload that leads
to arbitrary code execution within GRUB. The highest threat from
this vulnerability is to data confidentiality and integrity as well
as system availability.
* CVE-2020-14308
In grub2 versions before 2.06 the grub memory allocator doesn't
check for possible arithmetic overflows on the requested allocation
size. This leads the function to return invalid memory allocations
which can be further used to cause possible integrity,
confidentiality and availability impacts during the boot process.
* CVE-2020-14309
There's an issue with grub2 in all versions before 2.06 when
handling squashfs filesystems containing a symbolic link with name
length of UINT32 bytes in size. The name size leads to an
arithmetic overflow leading to a zero-size allocation further
causing a heap-based buffer overflow with attacker controlled data.
* CVE-2020-14310
An integer overflow in read_section_from_string may lead to a heap
based buffer overflow.
* CVE-2020-14311
An integer overflow in grub_ext2_read_link may lead to a heap-based
buffer overflow.
* CVE-2020-15706
GRUB2 contains a race condition in grub_script_function_create()
leading to a use-after-free vulnerability which can be triggered by
redefining a function whilst the same function is already
executing, leading to arbitrary code execution and secure boot
restriction bypass
* CVE-2020-15707
Integer overflows were discovered in the functions grub_cmd_initrd
and grub_initrd_init in the efilinux component of GRUB2, as shipped
in Debian, Red Hat, and Ubuntu (the functionality is not included
in GRUB2 upstream), leading to a heap-based buffer overflow. These
could be triggered by an extremely large number of arguments to the
initrd command on 32-bit architectures, or a crafted filesystem
with very large files on any architecture. An attacker could use
this to execute arbitrary code and bypass UEFI Secure Boot
restrictions. This issue affects GRUB2 version 2.04 and prior
versions.
