Narrative:

On climb out, I smelled something in the cabin. The cabin started to fill with a fog-like smoke. I walked through it to the front of the aircraft to evaluate just what it was. When I reached the front, I looked back into the cabin and saw that in fact it was smoke (fog). I went into the cockpit to tell the captain, and he informed me that he thought it was oil burning off the APU and that it had been written up before. We were going back to dfw and have it checked out. We didn't have to do an emergency checklist or prepare for an emergency evacuate/evacuation. We landed fine and proceeded on our flight with another aircraft.
