From: KP Singh <kpsingh@xxxxxxxxxx> This is in preparation to add a helper for BPF LSM programs to use IMA hashes when attached to LSM hooks. There are LSM hooks like inode_unlink which do not have a struct file * argument and cannot use the existing ima_file_hash API. An inode based API is, therefore, useful in LSM based detections like an executable trying to delete itself which rely on the inode_unlink LSM hook. Moreover, the ima_file_hash function does nothing with the struct file pointer apart from calling file_inode on it and converting it to an inode. Signed-off-by: KP Singh <kpsingh@xxxxxxxxxx>
There is no change for this patch compared to previous version, so you can carry my Ack. Acked-by: Yonghong Song <yhs@xxxxxx>
