====================
pull-request: bpf 2018-09-02
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix one remaining buggy offset override in sockmap's bpf_msg_pull_data()
when linearizing multiple scatterlist elements, from Tushar.
2) Fix BPF sockmap's misuse of ULP when a collision with another ULP is
found on map update where it would release existing ULP. syzbot found and
triggered this couple of times now, fix from John.
3) Add missing xskmap type to bpftool so it will properly show the type
on map dump, from Prashant.
