ima: handle multiple rules per write
Currently IMA will only accept one rule per write(). This patch allows IMA to accept writes which contain multiple rules but only processes one rule per write. \n is used as the delimiter between rules. IMA will return a short write indicating that it only accepted up to the first \n. This allows simple userspace utilities like cat to be used to load an IMA policy instead of needing a special userspace utility that understood 'one write per rule' Signed-off-by: Eric Paris <eparis@redhat.com> Acked-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org>
