When creating new file/directory, use security_dentry_init_security() to prepare selinux context for the new inode, then send openc/mkdir request to MDS, together with selinux xattr. security_dentry_init_security() only supports single security module and only selinux has dentry_init_security hook. So only selinux is supported for now. We can add support for other security modules once kernel has a generic version of dentry_init_security() Signed-off-by: "Yan, Zheng" <zyan@redhat.com> Reviewed-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
