getkeycreatecon_raw - Linux

Overview

getkeycreatecon_raw is a privileged command-line utility used to retrieve security-related information associated with a Linux kernel module. It is specifically designed to retrieve the precise time when a kernel module created a key creation mechanism. This information is crucial for assessing the integrity of kernel modules, particularly in the context of potential security vulnerabilities.

Syntax

getkeycreatecon_raw [-h] [--keyring KEYRING] module_name

Options/Flags

  • -h, –help: Display help information about the command.
  • –keyring KEYRING: Specify the keyring to search for the key creation mechanism. By default, it searches the "default" keyring.

Examples

Simple usage:

getkeycreatecon_raw my_module

Specify a different keyring:

getkeycreatecon_raw --keyring work my_module

Common Issues

  • Permission denied: Ensure that the user running the command has sufficient privileges to access the key creation mechanism information.
  • Invalid module name: Verify that the provided module name is valid and refers to an existing kernel module.

Integration

getkeycreatecon_raw can be integrated into automated security auditing scripts to verify the integrity of kernel modules. It can also be used in conjunction with other commands like ps and lsmod to gather comprehensive information about the loaded kernel modules.
