To prevent userspace from sending the TPM driver command to set the locality, we need to check every command that is sent from user space. To distinguish user space commands from internally sent commands we introduce an additional state flag STATE_DRIVER_COMMAND that is set while the driver sends this command. Similar to the TPM 2 space commands we return an error code when this command is detected.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
