    ====================
    pull-request: bpf-next 2018-10-08
    
    The following pull-request contains BPF updates for your *net-next* tree.
    
    The main changes are:
    
    1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow
    BPF programs to perform lookups for sockets in a network namespace. This would
    allow programs to determine early on in processing whether the stack is
    expecting to receive the packet, and perform some action (eg drop,
    forward somewhere) based on this information.
    
    2) per-cpu cgroup local storage from Roman Gushchin.
    Per-cpu cgroup local storage is very similar to simple cgroup storage
    except all the data is per-cpu. The main goal of per-cpu variant is to
    implement super fast counters (e.g. packet counters), which don't require
    neither lookups, neither atomic operations in a fast path.
    The example of these hybrid counters is in selftests/bpf/netcnt_prog.c
    
    3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet
    
    4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski
    
    5) rename of libbpf interfaces from Andrey Ignatov.
    libbpf is maturing as a library and should follow good practices in
    library design and implementation to play well with other libraries.
    This patch set brings consistent naming convention to global symbols.
    
    6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov
    to let Apache2 projects use libbpf
    
    7) various AF_XDP fixes from Björn and Magnus
