Pull networking fixes from David Miller: 1) Fix BPF filter validation of netlink attribute accesses, from Mathias Kruase. 2) Netfilter conntrack generation seqcount not initialized properly, from Andrey Vagin. 3) Fix comparison mask computation on big-endian in nft_cmp_fast(), from Patrick McHardy. 4) Properly limit MTU over ipv6, from Eric Dumazet. 5) Fix seccomp system call argument population on 32-bit, from Daniel Borkmann. 6) skb_network_protocol() should not use hard-coded ETH_HLEN, instead skb->mac_len needs to be used. From Vlad Yasevich. 7) We have several cases of using socket based communications to implement a tunnel. For example, some tunnels are encapsulations over UDP so we use an internal kernel UDP socket to do the transmits. These tunnels should behave just like other software devices and pass the packets on down to the next layer. Most importantly we want the top-level socket (eg TCP) that created the traffic to be charged for the SKB memory. However, once you get into the IP output path, we have code that assumed that whatever was attached to skb->sk is an IP socket. To keep the top-level socket being charged for the SKB memory, whilst satisfying the needs of the IP output path, we now pass in an explicit 'sk' argument. From Eric Dumazet. 8) ping_init_sock() leaks group info, from Xiaoming Wang. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (33 commits) cxgb4: use the correct max size for firmware flash qlcnic: Fix MSI-X initialization code ip6_gre: don't allow to remove the fb_tunnel_dev ipv4: add a sock pointer to dst->output() path. ipv4: add a sock pointer to ip_queue_xmit() driver/net: cosa driver uses udelay incorrectly at86rf230: fix __at86rf230_read_subreg function at86rf230: remove check if AVDD settled net: cadence: Add architecture dependencies net: Start with correct mac_len in skb_network_protocol Revert "net: sctp: Fix a_rwnd/rwnd management to reflect real state of the receiver's buffer" cxgb4: Save the correct mac addr for hw-loopback connections in the L2T net: filter: seccomp: fix wrong decoding of BPF_S_ANC_SECCOMP_LD_W seccomp: fix populating a0-a5 syscall args in 32-bit x86 BPF qlcnic: Do not disable SR-IOV when VFs are assigned to VMs qlcnic: Fix QLogic application/driver interface for virtual NIC configuration qlcnic: Fix PVID configuration on eSwitch port. qlcnic: Fix max ring count calculation qlcnic: Fix to send INIT_NIC_FUNC as first mailbox. qlcnic: Fix panic due to uninitialzed delayed_work struct in use. ...
