Pull networking fixes from David Miller:

 1) cfg80211_conn_scan() must be called with the sched_scan_mutex, fix
    from Artem Savkov.

 2) Fix regression in TCP ICMPv6 processing, we do not want to treat
    redirects as socket errors, from Christoph Paasch.

 3) Fix several recvmsg() msg_name kernel memory leaks into userspace,
    in ATM, AX25, Bluetooth, CAIF, IRDA, s390 IUCV, L2TP, LLC, Netrom,
    NFC, Rose, TIPC, and VSOCK.  From Mathias Krause and Wei Yongjun.

 4) Fix AF_IUCV handling of segmented SKBs in recvmsg(), from Ursula
    Braun and Eric Dumazet.

 5) CAN gw.c code does kfree() on SLAB cache memory, use
    kmem_cache_free() instead.  Fix from Wei Yongjun.

 6) Fix LSM regression on TCP SYN/ACKs, some LSMs such as SELINUX want
    an skb->sk socket context available for these packets, but nothing
    else requires it.  From Eric Dumazet and Paul Moore.

 7) Fix ipv4 address lifetime processing so that we don't perform
    sleepable acts inside of rcu_read_lock() sections, do them in an
    rtnl_lock() section instead.  From Jiri Pirko.

 8) mvneta driver accidently sets HW features after device registry, it
    should do so beforehand.  Fix from Willy Tarreau.

 9) Fix bonding unload races more correctly, from Nikolay Aleksandrov
    and Veaceslav Falico.

10) rtnl_dump_ifinfo() and rtnl_calcit() invoke nlmsg_parse() with wrong
    header size argument.  Fix from Michael Riesch.
