should not dereference anything from \"neigh\" (alias\n\"ptr\") until it has checked that the event is NETEVENT_NEIGH_UPDATE.\nOther events come with different structures pointed to by \"ptr\" and they\nmay be smaller than struct neighbour.\n\nMove the read of neigh->dev under the NETEVENT_NEIGH_UPDATE case.\n\nThe bug is mostly harmless, but it triggers KASAN on debug kernels:\n\n BUG: KASAN:
