1e5338ed06 boot/grub2: fix build race condition
Sometimes buildroot fails with:
../grub-core/kern/emu/hostfs.c:20:10: fatal error: config-util.h: No such file or directory
   20 | #include <config-util.h>
      |          ^~~~~~~~~~~~~~~

Add a patch which fixes the Makefile to correctly generate config-util.h
first.

Note: This re-adds a workaround to avoid re-running autoconf. This has
previously been used to avoid having to run the rather complex build
file generation machinery of GRUB2. See 7e64a050fb ("boot/grub2: Fix
GRUB i386-pc build with Ubuntu gcc"), but now we just need to touch
Makefile.in.

d9ff62c4cd pacakge: drop remnants of $(HOST_DIR)/usr
It's been ages (5 years at the next release) that we've not installed
host packages in $(HOST_DIR)/usr, but we still have a few packages that
reference it or install things in there.

Drop all of those in one fell swoop.

The run-time test still succeeds, and the following defconfig, which
should exercise all touched packages [*], does build:

[*] exceptions:
  - zfs was not tested: it needs a kernel to be built;
  - compiler-rt was not tsted: it needs llvm to be built, that takes
    ages, and other packages already reference the correct location for
    llvm-config, so it was assumed that is OK.

13bb419938 boot/grub2: update readme.txt details
For the Qemu-compatible UEFI firmware, the kraxel.org pointed to by
the readme.txt file is outdated. Instead, instruct users to use EDK2.
either by building it from source, or by grabbing pre-built ones, or
from their distributions.

While at it, drop the pci=nocrs information, as it is no longer
needed.

9f1b4d24ce boot/grub2: update to 2.06

needed beyond the version bump.

Spacing in the hash file is adjusted to the new Buildroot standard.

7a68960b68 boot/grub2/Config.in: add symbols to represent legacy and EFI boot
There are cases to want a synthetic information whether the legacy BIOS
or U-Boot boot scheme, or the EFI boot scheme, are enabled, without
resorting to testing all and each platforms.

This is already the cae in grub2 itself, for the configuration of the
BIOS/U-Boot boot partition, and builtin modules and configuration on one
hand, and the EFI builtin modules and configuraiton on the other hand.

It is also the case for mender-grubenv, which will want to know if
either or both are enabled, but without having to resort to testing all
the cases.

Add two new symbols, that each represent those conditions:
  * BR2_TARGET_GRUB2_HAS_LEGACY_BOOT
  * BR2_TARGET_GRUB2_HAS_EFI_BOOT

Each target selects the appropriate bool, which makes it much more
simple for other packages such as mender-grubenv to check if grub legacy
or EFI is selected.

And of course, we also make use of those symbols in grub2 itself, to
simplify the conditions for showing.hiding legacy and EFI options.

Additionally (but that does not merit being in its own patch), add a
comment on the closing 'endif' for the EFI part.

51682c03a8 boot/grub2: backport parallel-build fix

patch applied, it occurs much less frequently: from a 1/3rf failure
rate, I am now experiencing failures under the 1/10th mark.

82d1e8c628 boot/grub2: use none platform when building for host
When creating the image we are using the target modules. Building
the modules for host is then unnecessary.

Lets configure host Grub2 for the 'none' platform.

Note that this still installs a platform-dependent file:
    .../host/lib/grub/i386-pc/config.h

This file does not seem to have much purpose, but it is harmless.
We did not care to provide a post-isntall hook to remove it.

The tools were not installed anymore since we move from autotools to
generic-package. This patch fixes their installation.

We have decided to implement the install tool process by running the "make
install" command for each tuple. This allows to have all different
platforms Grub modules installed in the target. The drawback is the
overwrite of Grub2 binaries tools during each "make install" command. This
drawback is absolutely not important as it happens in the same package. This is
the best option to avoid unnecessary and more complexity to this package.

b68810e70c boot/grub2: add support to build multiple Grub2 configurations in the same build
When Grub2 is build it is configured only for one boot set-up, BIOS Legacy,
EFI 32 bit or EFI 64 bit. It can not deal with several boot set-up on the
same image.

This patch allows to build Grub2 for different configurations simultaneously.
To cover Grub2 configuration of legacy BIOS platforms (32-bit), 32-bit EFI
BIOS and 64-bit EFI BIOS in the same build, multi-build system felt much more
reasonable to just extend the grub2 package into 3 packages.

We can no longer use autotools-package as a consequence of this multi-build, and
we have to resort to generic-package and a partial duplication of
the autotools-infra. Grub2 was already using custom option like --prefix or
--exec-prefix so this won't add much more weirdness.

We use a GRUB2_TUPLES list to describe all the configurations selected.
For each boot case described in the GRUB2_TUPLES list, it configures and
builds Grub2 in a separate folder named build-$(tuple).
We use a foreach loop to make actions on each tuple selected.

We have to separate the BR2_TARGET_GRUB2_BUILTIN_MODULES and the
BR2_TARGET_GRUB2_BUILTIN_CONFIG for each BIOS or EFI boot cases.

3efb5e31fc board, boot, package: remove usage of startup.nsh in EFI partition
The startup.nsh file is useless to boot EFI payloads. We just need to
follow the naming detection specified in the UEFI spec.
The EFI payload need to be placed in the boot/efi folder in the EFI partition
and follow the architecture naming as described below:
32bit : bootia32.efi
x64 : bootx64.efi
aarch32 : bootarm.efi
aarch64 : bootaa64.efi

This naming is already right in the packages involved (systemd, grub2,
gummiboot), therefore we just need to drop the generation of the
startup.nsh file.

The usage of the startup.nsh in genimage is also dropped to avoid errors in
the image generation.

7cb51d4843 boot/grub2: workaround breakage with -O2, -O3 build
When grub2 (i386-pc) is built with -O2 or -O3 it is unable to boot
and the system will reboot in a loop.

Tony Battersby has bisected [0] the error down to this security bugfix:
boot/grub2/0132-kern-parser-Fix-a-stack-buffer-overflow.patch
There is also a bug report by Peter Seiderer about this [1].

As discussed on the mailing list [2], this patch introduces a workaround
in the grub2.mk overriding the global optimization settings with -Os
which results in a booting system.

1bad507220 boot/grub2: Backport 2021/03/02 securify fixes
Details: https://lists.gnu.org/archive/html/grub-devel/2021-03/msg00007.html

As detailed in commit 7e64a050fb, it is
difficult to utilize the upstream patches directly, so a number of
patches include changes to generated files so that we don't need invoke
the gentpl.py script.

In addition to the security fixes, these required patches has been
backported:

  f76a27996 efi: Make shim_lock GUID and protocol type public
  04ae030d0 efi: Return grub_efi_status_t from grub_efi_get_variable()
  ac5c93675 efi: Add a function to read EFI variables with attributes
  d7e54b2e5 efi: Add secure boot detection

The following security issues are fixed:

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

The GRUB2 upstream reintroduced the CVE-2020-15705. This refers to a distro
specific flaw which made upstream in the mentioned version.

If certificates that signed GRUB2 are installed into db, GRUB2 can be booted

down, yet it could have been tampered.

This flaw only affects upstream and distributions using the shim_lock verifier.

2f7a8021b5 boot/grub2: Backport Boothole securify fixes
Details: https://lists.gnu.org/archive/html/grub-devel/2020-07/msg00034.html

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.

7e64a050fb boot/grub2: Fix GRUB i386-pc build with Ubuntu gcc
Backport a patch from upstream to fix the build on certain versions of
gsc, notably:

    Ubuntu 19.10 with gcc (Ubuntu 8.3.0-26ubuntu1~19.10) 8.3.0
    Ubuntu 19.10 with gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008

The upstream patch is simply a change in the gentpl.py script, which is
used to generate parts of the automake machinery, so if we just backport
the upstream patch, we need to call the script to regenerate those files.

However, the modified script is a python script, so we would need to add
a dependency on host-python (2 or 3), which is not so nice.

Furthermore, calling the script is not enough: it needs a specific set
of optionss for each file it is to generate. That set of options is not
static; it is constructed in the convoluted autogen.sh. Calling
autogen.sh is usally not so good an idea in the Buildroot context, and
indeed this fails becasue it calls to autoreconf, but without our
carefuly crafted options and environment variables.

There was a little light in the tunnel, in that autogen.sh can be told
not to run autoreconf, by setting the environemnt variable
FROM_BOOTSTRAP to an non-=empty string, but this is fraught with various
other side-effects, as in that cause, autogen.sh expects to be valled by
an upper sciopt, bootstrap, which is not provided in the tarball
distribution...

So, between all those issues, autogen, bootstrap, and a host-python (2
or 3) dependency, we choose another route: path the script *and* the one
generated file affected by the change. Since that patched file is a .am
file, we also patch the corresponding .in file

However, we're faced with another issue: the other generated file is
now older than the script, so the automake machinery will now want to
re-run autoconf et al during the build step, which is still not a good
idea for us. So we touch the other generated file so it is mopre recent
than the script.

This is still not sufficient, because the patched file also has a
dependency on the generated file, so we need to touch as well.

273a27804a boot/grub2: enable support for arm and aarch64 targets
This commit enables the arm-uboot, arm-efi and aarch64-efi grub2
platforms in Buildroot.

With the uboot platform, the grub2 image gets built as a u-boot image
and is loaded from u-boot through a regular "bootm". The only
requirement from the u-boot side in order to allow this is that u-boot
is built with CONFIG_API enabled. CONFIG_API seems to not be enabled
by default in most in-tree configurations, however, it seems to be
available for quite some time now. So it might be possible to use this
even on older u-boot versions. This is available only for arm
(32-bit).

With the efi platform, grub2 gets built as an EFI executable. This
allows EFI firmware to find and load it similarly as it can be done
for x86_64. Also, since u-boot v2016.05, u-boot is able to load and
boot an EFI executable, so the uboot efi platform can also be used
from u-boot in recent versions. This has been enabled (mostly) by
default for ARM u-boot. efi platform is available for both arm and
aarch64.

ac0719e086 boot/grub2: separate target and host builds
grub2 requires the host grub2-mkimage tool to build some of its target
images. The current way of building this tool in the grub2 package is
to perform a simultaneous host-tools/target-bootloader build during
the grub2 build step.

This method makes the recipe complex to understand, and proved to be a
complication during the work to enable grub2 support for architectures
other than x86.

This patch tries to do a better separation between the build of grub2
host tools and target boot loader image, as a partial step to enable
grub2 to build for other architectures.

to make it build properly even when SSP support is enabled.

However, commit 20a4583ebf ("security

passed, and they are now passed in CPPFLAGS instead of CFLAGS, making
the fix introduced by 2a27294e9a no

0d643fd3e8 core: change the strip command from a choice to a boolean
Curently, we have a choice to select between stripping and not
stripping. This is legacy code from back when we had a third option,
sstrip (super-strip).

Since we removed sstrip, stripping or not stripping is now just a
boolean rather than a choice.

Make it so.

We make BR2_STRIP_strip default to 'y' to keep the current behaviour of
defaulting to stripping.

Move BR2_STIP_none to legacy, and instruct the user to review the new
setting.

Drop any reference to BR2_STRIP_none in comments.

fc174b7057 grub2: fix build with BR2_STRIP_none
grub2 assumes the strip command will generate output and the output should
always be stripped - so, just use the $(TARGET_CROSS)strip to make sure that
the build succeeds regardless of the buildroot strip configuration.

890c9e761b grub2: pass target NM, OBJCOPY and STRIP
Fixes https://bugs.busybox.net/show_bug.cgi?id=8256

grub2's build system interprets CC, CFLAGS and CPPFLAGS as for the host
and uses TARGET_CC etc. for the target. However, NM, OBJCOPY and STRIP
are used for the target. We currently pass the host-versions of these
tools as part of $(HOST_CONFIGURE_OPTS).

While we're at it, also pass TARGET_LDFLAGS.

This problem had not been noticed up to now because usually we build on
an x86 machine for the x86 architecture, so the binutils are compatible.
However, this is not true on an i386 when building for x86_64.

8decd25477 grub2: prepare and install El Torito image
In order to support ISO9660 bootable images that rely on Grub 2, this
commit modifies thr Grub 2 makefile to generate and install an El
Torito image. Such an image is simply produced by concatenating the
cdboot.img provided by Grub 2, and the Grub 2 image generated by
Buildroot using grub-mkimage.

Since this action is so simple and cost-free, we don't bother adding a
Grub 2 sub-option for that, and simply generate the El Torito image
unconditionally.

When x86-64-efi platform is selected, grub2 automatically adds -m64 to the
CFLAGS. This makes the configure script failed when the toolchain does not
have multilib support (like the Buildroot ones).
