====================
pull-request: bpf 2019-05-16

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix a use after free in __dev_map_entry_free(), from Eric.

2) Several sockmap related bug fixes: a splat in strparser if
   it was never initialized, remove duplicate ingress msg list
   purging which can race, fix msg->sg.size accounting upon
   skb to msg conversion, and last but not least fix a timeout
   bug in tcp_bpf_wait_data(), from John.

3) Fix LRU map to avoid messing with eviction heuristics upon
   syscall lookup, e.g. map walks from user space side will
   then lead to eviction of just recently created entries on
   updates as it would mark all map entries, from Daniel.

4) Don't bail out when libbpf feature probing fails. Also
   various smaller fixes to flow_dissector test, from Stanislav.

5) Fix missing brackets for BTF_INT_OFFSET() in UAPI, from Gary.
