====================
pull-request: bpf 2018-06-16
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a panic in devmap handling in generic XDP where return type
of __devmap_lookup_elem() got changed recently but generic XDP
code missed the related update, from Toshiaki.
2) Fix a freeze when BPF progs are loaded that include BPF to BPF
calls when JIT is enabled where we would later bail out via error
path w/o dropping kallsyms, and another one to silence syzkaller
splats from locking prog read-only, from Daniel.
3) Fix a bug in test_offloads.py BPF selftest which must not assume
that the underlying system have no BPF progs loaded prior to test,
and one in bpftool to fix accuracy of program load time, from Jakub.
4) Fix a bug in bpftool's probe for availability of the bpf(2)
BPF_TASK_FD_QUERY subcommand, from Yonghong.
5) Fix a regression in AF_XDP's XDP_SKB receive path where queue
id check got erroneously removed, from Björn.
6) Fix missing state cleanup in BPF's xfrm tunnel test, from William.
7) Check tunnel type more accurately in BPF's tunnel collect metadata
kselftest, from Jian.
8) Fix missing Kconfig fragments for BPF kselftests, from Anders.
