pull-request: bpf 2017-12-02
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a compilation warning in xdp redirect tracepoint due to
missing bpf.h include that pulls in struct bpf_map, from Xie.
2) Limit the maximum number of attachable BPF progs for a given
perf event as long as uabi is not frozen yet. The hard upper
limit is now 64 and therefore the same as with BPF multi-prog
for cgroups. Also add related error checking for the sample
BPF loader when enabling and attaching to the perf event, from
Yonghong.
3) Specifically set the RLIMIT_MEMLOCK for the test_verifier_log
case, so that the test case can always pass and not fail in
some environments due to too low default limit, also from
Yonghong.
4) Fix up a missing license header comment for kernel/bpf/offload.c,
from Jakub.
5) Several fixes for bpftool, among others a crash on incorrect
arguments when json output is used, error message handling
fixes on unknown options and proper destruction of json writer
for some exit cases, all from Quentin.
