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.
