Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "Mostly netfilter bug fixes in here, but we have some bits elsewhere as well. 1) Don't do SNAT replies for non-NATed connections in IPVS, from Julian Anastasov. 2) Don't delete conntrack helpers while they are still in use, from Liping Zhang. 3) Fix zero padding in xtables's xt_data_to_user(), from Willem de Bruijn. 4) Add proper RCU protection to nf_tables_dump_set() because we cannot guarantee that we hold the NFNL_SUBSYS_NFTABLES lock. From Liping Zhang. 5) Initialize rcv_mss in tcp_disconnect(), from Wei Wang. 6) smsc95xx devices can't handle IPV6 checksums fully, so don't advertise support for offloading them. From Nisar Sayed. 7) Fix out-of-bounds access in __ip6_append_data(), from Eric Dumazet. 8) Make atl2_probe() propagate the error code properly on failures, from Alexey Khoroshilov. 9) arp_target[] in bond_check_params() is used uninitialized. This got changes from a global static to a local variable, which is how this mistake happened. Fix from Jarod Wilson. 10) Fix fallout from unnecessary NULL check removal in cls_matchall, from Jiri Pirko. This is definitely brown paper bag territory..." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (26 commits) net: sched: cls_matchall: fix null pointer dereference vsock: use new wait API for vsock_stream_sendmsg() bonding: fix randomly populated arp target array net: Make IP alignment calulations clearer. bonding: fix accounting of active ports in 3ad net: atheros: atl2: don't return zero on failure path in atl2_probe() ipv6: fix out of bound writes in __ip6_append_data() bridge: start hello_timer when enabling KERNEL_STP in br_stp_start smsc95xx: Support only IPv4 TCP/UDP csum offload arp: always override existing neigh entries with gratuitous ARP arp: postpone addr_type calculation to as late as possible arp: decompose is_garp logic into a separate function arp: fixed error in a comment tcp: initialize rcv_mss to TCP_MIN_MSS instead of 0 netfilter: xtables: fix build failure from COMPAT_XT_ALIGN outside CONFIG_COMPAT ebtables: arpreply: Add the standard target sanity check netfilter: nf_tables: revisit chain/object refcounting from elements netfilter: nf_tables: missing sanitization in data from userspace netfilter: nf_tables: can't assume lock is acquired when dumping set elems netfilter: synproxy: fix conntrackd interaction ...
