An information handling system includes a first memory that stores a firmware image associated with the baseboard management controller. The baseboard management controller begins execution of a kernel, which in turn performs a boot operation of the information handling system. The baseboard management controller begins a file system initialization program. During the boot operation, the baseboard management controller performs a full read and cryptographic verification of the firmware image via a DM-Verity daemon of the file system initialization program. In response to the full read of the firmware image being completed, the baseboard management controller provides a flush command to the kernel via the DM-Verity daemon. The baseboard management controller flushes a cache buffer associated with the baseboard management controller via the kernel.

Cryptographically verifying a firmware image with boot speed in an information handling system

An information handling system includes a first memory and a baseboard management controller. The first memory stores a first firmware partition and a second firmware partition. The baseboard management controller includes a second memory. The baseboard management controller begins execution of a DM-Verity daemon, and performs periodic patrol reads of the first firmware partition. The baseboard management controller detects one or more block failures in the first firmware partition, and stores information associated with the one or more block failures in a message box of the second memory. In response to the entire first firmware partition being scanned, the baseboard management controller switches a boot partition from the first firmware partition to the second firmware partition, and initiates a reboot of the information handling system.

Multiple block error correction in an information handling system

A management system for an information handling system includes a memory device and a management controller. The memory device includes a primary firmware image and a backup firmware image. The management controller boots the management system. The boot of the management system includes a read of a first block at an offset within the primary firmware image. The management controller further determines that the read of the first block had a first read error, and reboots the management system in response to determining that the read of the first block had the first read error. The reboot of the management system includes a read of a second block at the offset within the backup firmware image.
