Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull yet more networking updates from David Miller: 1) Various fixes to the new Redpine Signals wireless driver, from Fariya Fatima. 2) L2TP PPP connect code takes PMTU from the wrong socket, fix from Dmitry Petukhov. 3) UFO and TSO packets differ in whether they include the protocol header in gso_size, account for that in skb_gso_transport_seglen(). From Florian Westphal. 4) If VLAN untagging fails, we double free the SKB in the bridging output path. From Toshiaki Makita. 5) Several call sites of sk->sk_data_ready() were referencing an SKB just added to the socket receive queue in order to calculate the second argument via skb->len. This is dangerous because the moment the skb is added to the receive queue it can be consumed in another context and freed up. It turns out also that none of the sk->sk_data_ready() implementations even care about this second argument. So just kill it off and thus fix all these use-after-free bugs as a side effect. 6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti. 7) pktgen needs to do locking properly for LLTX devices, from Daniel Borkmann. 8) xen-netfront driver initializes TX array entries in RX loop :-) From Vincenzo Maffione. 9) After refactoring, some tunnel drivers allow a tunnel to be configured on top itself. Fix from Nicolas Dichtel. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (46 commits) vti: don't allow to add the same tunnel twice gre: don't allow to add the same tunnel twice drivers: net: xen-netfront: fix array initialization bug pktgen: be friendly to LLTX devices r8152: check RTL8152_UNPLUG net: sun4i-emac: add promiscuous support net/apne: replace IS_ERR and PTR_ERR with PTR_ERR_OR_ZERO net: ipv6: Fix oif in TCP SYN+ACK route lookup. drivers: net: cpsw: enable interrupts after napi enable and clearing previous interrupts drivers: net: cpsw: discard all packets received when interface is down net: Fix use after free by removing length arg from sk_data_ready callbacks.
