IMA records file "Time of Measure, Time of Use (ToMToU)" and "open writers" integrity violations by adding a record to the measurement list containing one value (0x00's), but extending the TPM with a different value (0xFF's). To avoid known file integrity violations, the builtin "tcb" measurement policy should be replaced with a custom policy as early as possible. This patch renames the existing "--validate" option to "--ignore-violations". Suggested-by: Stephen Smalley <stephen.smalley.work@gmail.com> Signed-off-by: Mimi Zohar <zohar@linux.ibm.com>
