This is similar to the "send over AF_PACKET" issue we were discussing the other week. It seems we need a real resolution to this issue. To recap: 1) We want to charge memory to the top-level socket. 2) However during encapsulations etc. we can end up in IP stack which expects only IP sockets to be attached to skb->sk I suspect that in the short term we may have to bit the bullet and compromise #2, and do flow control via the tunnel's socket. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
