====================
pull-request: bpf 2019-03-09
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a crash in AF_XDP's xsk_diag_put_ring() which was passing
wrong queue argument, from Eric.
2) Fix a regression due to wrong test for TCP GSO packets used in
various BPF helpers like NAT64, from Willem.
3) Fix a sk_msg strparser warning which asserts that strparser must
be stopped first, from Jakub.
4) Fix rejection of invalid options/bind flags in AF_XDP, from Björn.
5) Fix GSO in bpf_lwt_push_ip_encap() which must properly set inner
headers and inner protocol, from Peter.
6) Fix a libbpf leak when kernel does not support BTF, from Nikita.
7) Various BPF selftest and libbpf build fixes to make out-of-tree
compilation work and to properly resolve dependencies via fixdep
target, from Stanislav.
8) Fix rejection of invalid ldimm64 imm field, from Daniel.
9) Fix bpf stats sysctl compile warning of unused helper function
proc_dointvec_minmax_bpf_stats() under some configs, from Arnd.
10) Fix couple of warnings about using plain integer as NULL, from Bo.
11) Fix some BPF sample spelling mistakes, from Colin.
