Hi David,

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

The main changes are:

1) Fix tcp_bpf_recvmsg() to return -EAGAIN instead of 0 in non-blocking
   case when no data is available yet, from John.

2) Fix a compilation error in libbpf_attach_type_by_name() when compiled
   with clang 3.8, from Andrey.

3) Fix a partial copy of map pointer on scalar alu and remove id
   generation for RET_PTR_TO_MAP_VALUE return types, from Daniel.

4) Add unlimited memlock limit for kernel selftest's flow_dissector_load
   program, from Yonghong.

5) Fix ping for some BPF shell based kselftests where distro does not
   ship "ping -6" anymore, from Li.

Please consider pulling these changes from:

Thanks a lot!
