    ====================
    pull-request: bpf 2019-06-07
    
    The following pull-request contains BPF updates for your *net* tree.
    
    The main changes are:
    
    1) Fix several bugs in riscv64 JIT code emission which forgot to clear high
       32-bits for alu32 ops, from Björn and Luke with selftests covering all
       relevant BPF alu ops from Björn and Jiong.
    
    2) Two fixes for UDP BPF reuseport that avoid calling the program in case of
       __udp6_lib_err and UDP GRO which broke reuseport_select_sock() assumption
       that skb->data is pointing to transport header, from Martin.
    
    3) Two fixes for BPF sockmap: a use-after-free from sleep in psock's backlog
       workqueue, and a missing restore of sk_write_space when psock gets dropped,
       from Jakub and John.
    
    4) Fix unconnected UDP sendmsg hook API which is insufficient as-is since it
       breaks standard applications like DNS if reverse NAT is not performed upon
       receive, from Daniel.
    
    5) Fix an out-of-bounds read in __bpf_skc_lookup which in case of AF_INET6
       fails to verify that the length of the tuple is long enough, from Lorenz.
    
    6) Fix libbpf's libbpf__probe_raw_btf to return an fd instead of 0/1 (for
       {un,}successful probe) as that is expected to be propagated as an fd to
       load_sk_storage_btf() and thus closing the wrong descriptor otherwise,
       from Michal.
    
    7) Fix bpftool's JSON output for the case when a lookup fails, from Krzesimir.
    
    8) Minor misc fixes in docs, samples and selftests, from various others.
