Narrative:
Upon climb out at about 3000-5000 ft AGL faint smoke odor detected by flight crew; thought it was residual due to maintenance the night prior (flight canceled due to smoke in cabin at gate due to APU oil leak -- maintenance repaired overnight). Heard the cabin chimes associated with a lavatory smoke detector soon followed by cabin crew bells notification of smoke in the cabin. We notified departure control and immediately started a descent for ZZZ. We were issued a clearance to land on runway 19R. We completed the immediate return checklist and returned to the ZZZ airport. Crash fire rescue equipment were in position and followed aircraft to the gate. No evacuate/evacuation was needed after landing; so we proceeded to the gate. The night prior; we had experienced smoke in the cabin on the ground in ZZZ; and it was determined that the APU had an internal oil leak which had compromised the air conditioning system. Company maintenance had spent the night working on the aircraft to return to service.
