evm: reset EVM status when file attributes change
The EVM verification status is cached in iint->evm_status and if it was successful, never re-verified again when IMA passes the 'iint' to evm_verifyxattr(). When file attributes or extended attributes change, we may wish to re-verify EVM integrity as well. For example, after setting a digital signature we may need to re-verify the signature and update the iint->flags that there is an EVM signature. This patch enables that by resetting evm_status to INTEGRITY_UKNOWN state. Changes in v2: * Flag setting moved to EVM layer Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@huawei.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
