Thomas Petazzoni ce99484b3a boot/grub2: add patches to fix numerous CVEs
This patch brings the entire stack of Debian patches on grub2 titled
"cve-2025-jan" and available at:

  https://salsa.debian.org/grub-team/grub/-/tree/debian/2.12-9/debian/patches/cve-2025-jan?ref_type=tags

As of this exact Debian grub2 version 2.12-9. Some minor conflicts had
to be fixed. All patches are in upstream Grub master, but mixed with
hundreds of other changes, which is why Debian's effort to backport
them has been leveraged here.

In addition to those patches, 2 extra patches are added:

 0073-net-drivers-ieee1275-ofnet-Add-missing-grub_malloc.patch
 0074-Constant-time-grub_crypto_memcmp.patch

The first one fixes an issue in one of the earlier patches. The fix is
not in Debian, but is in upstream Grub.

The second one fixes another CVE, not fixed in Debian, but fixed in
OpenSUSE. This fix is not upstream as upstream has decided to move to
libgcrypt instead to avoid the problem, but that's a fairly large
change.

Overall, this patch fixes all CVEs currently reported by pkg-stats
against our grub2 package, namely:

CVE-2024-45777
CVE-2024-45778
CVE-2024-45779
CVE-2024-45780
CVE-2024-45782
CVE-2024-56737
CVE-2024-56738
CVE-2025-0678
CVE-2025-0684
CVE-2025-0685
CVE-2025-0686
CVE-2025-0689
CVE-2025-1125

With the previous fixes on runtime tests added (to use glibc
toolchains to build grub2 tests), this commit successfully passes all
tests:

- The ISO9660 tests that use grub2:

- The grub2 tests:

[Julien:
 - fix patch #72 upstream link to point to the initial patch
   sumbission rather than a reply
 - merge two _IGNORE_CVES blocks for patch #50 into a single one
 - order _IGNORE_CVES blocks by numerical patch order
 - order numerically the CVE list in commit log
 - add a "Fixes:" tag in patch #74 since its commit log does not
   mention the CVE.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
