From 9d93d7877c9158d059028681b66a0c192f85c64d Mon Sep 17 00:00:00 2001 From: Vadim Pasternak Date: Sat, 2 Oct 2021 12:32:35 +0300 Subject: [PATCH] platform_data/mlxreg: Add new field for secured access Extend structure 'mlxreg_core_data' with the field "secured". The purpose of this field is to restrict access to some attributes, if kernel is configured with security options, like: LOCK_DOWN_KERNEL_FORCE_CONFIDENTIALITY. Access to some attributes, which for example, allow burning of some hardware components, like FPGA, CPLD, SPI, etcetera can break the system. In case user does not want to allow such access, it can disable it by setting security options.
