All files matching a "measure" rule must be included in the IMA measurement list, even when the file hash cannot be calculated. Similarly, all files matching an "audit" rule must be audited, even when the file hash can not be calculated. The file data hash field contained in the IMA measurement list template data will contain 0's instead of the actual file hash digest. Note: In general, adding, deleting or in anyway changing which files are included in the IMA measurement list is not a good idea, as it might result in not being able to unseal trusted keys sealed to a specific TPM PCR value. This patch not only adds file measurements that were not previously measured, but specifies that the file hash value for these files will be 0's. As the IMA measurement list ordering is not consistent from one boot to the next, it is unlikely that anyone is sealing keys based on the IMA measurement list. Remote attestation servers should be able to process these new measurement records, but might complain about these unknown records.

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.
