Subject: [PATCH v1 0/1] Introduction of HP-BIOSCFG driver
Date: Mon, 10 Oct 2022 11:23:25 -0500 [thread overview]
Message-ID: <20221010162326.12957-1-jorge.lopez2@hp.com> (raw)
The purpose for this patch is submit HP BIOSCFG driver to be list of
HP Linux kernel drivers. HP BIOS Configuration driver purpose is to
provide a driver supporting the latest sysfs class firmware attributes
framework allowing the user to change BIOS settings and security
solutions on HP Inc.’s commercial notebooks.
Many features of HP Commercial PC’s can be managed using Windows
Management Instrumentation (WMI). WMI is an implementation of Web-Based
Enterprise Management (WBEM) that provides a standards-based interface
for changing and monitoring system settings. HP BISOCFG driver provides
a native Linux solution and the exposed features facilitates the
migration to Linux environments.
The Linux security features to be provided in hp-bioscfg driver enables
managing the BIOS settings and security solutions via sysfs, a virtual
filesystem that can be used by user-mode applications. The new
documentation cover features such Secure Platform Management, Sure
Admin, and Sure Start. Each section provides security feature
description and identifies sysfs directories and files exposed by
the driver.
Many HP Commercial PC’s include a feature called Secure Platform
Management (SPM), which replaces older password-based BIOS settings
management with public key cryptography. PC secure product management
begins when a target system is provisioned with cryptographic keys
that are used to ensure the integrity of communications between system
management utilities and the BIOS.
HP Commercial PC’s have several BIOS settings that control its behaviour
and capabilities, many of which are related to security. To prevent
unauthorized changes to these settings, the system can be configured
to use a Sure Admin cryptographic signature-based authorization string
that the BIOS will use to verify authorization to modify the setting.
