Pull networking fixes from David Miller:

 1) The netlink attribute passed in to dev_set_alias() is not
    necessarily NULL terminated, don't use strlcpy() on it. From
    Alexander Potapenko.

 2) Fix implementation of atomics in arm64 bpf JIT, from Daniel
    Borkmann.

 3) Correct the release of netdevs and driver private data in certain
    circumstances.

 4) Sanitize netlink message length properly in decnet, from Mateusz
    Jurczyk.

 5) Don't leak kernel data in rtnl_fill_vfinfo() netlink blobs. From
    Yuval Mintz.

 6) Hash secret is never initialized in ipv6 ILA translation code, from
    Arnd Bergmann. I guess those clang warnings about unused inline
    functions are useful for something!

 7) Fix endian selection in bpf_endian.h, from Daniel Borkmann.

 8) Sanitize sockaddr length before dereferncing any fields in AF_UNIX
    and CAIF. From Mateusz Jurczyk.

 9) Fix timestamping for GMAC3 chips in stmmac driver, from Mario
    Molitor.

10) Do not leak netdev on dev_alloc_name() errors in mac80211, from
    Johannes Berg.

11) Fix locking in sctp_for_each_endpoint(), from Xin Long.

12) Fix wrong memset size on 32-bit in snmp6, from Christian Perle.

13) Fix use after free in ip_mc_clear_src(), from WANG Cong.

14) Fix regressions caused by ICMP rate limiting changes in 4.11, from
    Jesper Dangaard Brouer.
