Nobody can grant, that the pointer got by you from the struct net is not going to become free, unless you provide this security by yourself. But if you call net_generic to get some pointer other than tun_net, then you're fine (due to RCU), providing you play the same rules with the pointer you're getting. Maybe I'm missing something in your question, can you provide some testcase, that you suspect may cause an OOPS? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
