| Doc Text | Cause: If a path changed its wwid after being added to a multipath device, multipathd would create a new device. This lead to the path being in both devices. Consequence: If users changed with uid_attribute after multipath devices were created, and then removed the devices, multipathd would try to access freed memory and crash. Fix: Multipathd no longer allows the paths wwid to be changed while it is being used in a multipath device Result: multipathd no longer crashes in this scenario. |
