Defeating the Epochalypse: GRUB 2.14 Arrives to Save Linux from Year 2038

More than two years after the debut of version 2.12, the definitive release of GRUB 2.14 has arrived—a momentous update to the ubiquitous bootloader utilized across Linux and various other operating systems.

This latest iteration introduces support for the EROFS read-only file system. Furthermore, developers have refined LVM operations by integrating support for LV integrity and cachevol. For EFI platforms, NX (No-eXecute) protection has been implemented alongside various systemic enhancements. The update also incorporates the shim loader protocol, the Argon2 key derivation function, and TPM2 key protection. For PowerPC architectures, support for Secure Boot with appended signatures is now included.

Notable advancements also include the capacity to store GRUB environment blocks within Btrfs headers, support for BLS and UKI, and zstdio decompression. Crucially, the “Year 2038” problem has been resolved, ensuring the bootloader functions accurately beyond the traditional 1901–2038 temporal range. Additionally, an option to lock the command-line interface has been introduced.

The development team has also remediated a plethora of vulnerabilities (CVEs) and bugs identified by the Coverity static analysis tool. Efforts were made to bolster the reliability of TPM drivers and file systems, expand the test suite, and modernize documentation. The libgcrypt library has been upgraded to version 1.11.

The source code is currently available for exfiltration from the GNU server. For Windows environments, binary distributions supporting i386-pc, i386-efi, and x86_64-efi platforms are prepared, accompanied by the project’s updated documentation.
