pull-request: bpf 2018-11-25

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

The main changes are:

1) Fix an off-by-one bug when adjusting subprog start offsets after
   patching, from Edward.

2) Fix several bugs such as overflow in size allocation in queue /
   stack map creation, from Alexei.

3) Fix wrong IPv6 destination port byte order in bpf_sk_lookup_udp
   helper, from Andrey.

4) Fix several bugs in bpftool such as preventing an infinite loop
   in get_fdinfo, error handling and man page references, from Quentin.

5) Fix a warning in bpf_trace_printk() that wasn't catching an
   invalid format string, from Martynas.

6) Fix a bug in BPF cgroup local storage where non-atomic allocation
   was used in atomic context, from Roman.

7) Fix a NULL pointer dereference bug in bpftool from reallocarray()
   error handling, from Jakub and Wen.

8) Add a copy of pkt_cls.h and tc_bpf.h uapi headers to the tools
   include infrastructure so that bpftool compiles on older RHEL7-like
   user space which does not ship these headers, from Yonghong.

9) Fix BPF kselftests for user space where to get ping test working
   with ping6 and ping -6, from Li.
