Hi David,
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.
