Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Revert iwlwifi reclaimed packet tracking, it causes problems for a bunch of folks. From Emmanuel Grumbach. 2) Work limiting code in brcmsmac wifi driver can clear tx status without processing the event. From Arend van Spriel. 3) rtlwifi USB driver processes wrong SKB, fix from Larry Finger. 4) l2tp tunnel delete can race with close, fix from Tom Parkin. 5) pktgen_add_device() failures are not checked at all, fix from Cong Wang. 6) Fix unintentional removal of carrier off from tun_detach(), otherwise we confuse userspace, from Michael S. Tsirkin. 7) Don't leak socket reference counts and ubufs in vhost-net driver, from Jason Wang. 8) vmxnet3 driver gets it's initial carrier state wrong, fix from Neil Horman. 9) Protect against USB networking devices which spam the host with 0 length frames, from Bjørn Mork. 10) Prevent neighbour overflows in ipv6 for locally destined routes, from Marcelo Ricardo. This is the best short-term fix for this, a longer term fix has been implemented in net-next. 11) L2TP uses ipv4 datagram routines in it's ipv6 code, whoops. This mistake is largely because the ipv6 functions don't even have some kind of prefix in their names to suggest they are ipv6 specific. From Tom Parkin. 12) Check SYN packet drops properly in tcp_rcv_fastopen_synack(), from Yuchung Cheng. 13) Fix races and TX skb freeing bugs in via-rhine's NAPI support, from Francois Romieu and your's truly. 14) Fix infinite loops and divides by zero in TCP congestion window handling, from Eric Dumazet, Neal Cardwell, and Ilpo Järvinen. 15) AF_PACKET tx ring handling can leak kernel memory to userspace, fix from Phil Sutter. 16) Fix error handling in ipv6 GRE tunnel transmit, from Tommi Rantala. 17) Protect XEN netback driver against hostile frontend putting garbage into the rings, don't leak pages in TX GOP checking, and add proper resource releasing in error path of xen_netbk_get_requests(). From Ian Campbell. 18) SCTP authentication keys should be cleared out and released with kzfree(), from Daniel Borkmann. 19) L2TP is a bit too clever trying to maintain skb->truesize, and ends up corrupting socket memory accounting to the point where packet sending is halted indefinitely. Just remove the adjustments entirely, they aren't really needed. From Eric Dumazet. 20) ATM Iphase driver uses a data type with the same name as the S390 headers, rename to fix the build. From Heiko Carstens. 21) Fix a typo in copying the inner network header offset from one SKB to another, from Pravin B Shelar. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (56 commits) net: sctp: sctp_endpoint_free: zero out secret key data net: sctp: sctp_setsockopt_auth_key: use kzfree instead of kfree atm/iphase: rename fregt_t -> ffreg_t net: usb: fix regression from FLAG_NOARP code l2tp: dont play with skb->truesize net: sctp: sctp_auth_key_put: use kzfree instead of kfree netback: correct netbk_tx_err to handle wrap around. xen/netback: free already allocated memory on failure in xen_netbk_get_requests xen/netback: don't leak pages on failure in xen_netbk_tx_check_gop. xen/netback: shutdown the ring if it contains garbage. net: qmi_wwan: add more Huawei devices, including E320 net: cdc_ncm: add another Huawei vendor specific device ipv6/ip6_gre: fix error case handling in ip6gre_tunnel_xmit() tcp: fix for zero packets_in_flight was too broad brcmsmac: rework of mac80211 .flush() callback operation ssb: unregister gpios before unloading ssb bcma: unregister gpios before unloading bcma rtlwifi: Fix scheduling while atomic bug net: usbnet: fix tx_dropped statistics tcp: ipv6: Update MIB counters for drops ...
