Subject: pull-request: bpf-next 2019-07-09
Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Lots of libbpf improvements: i) addition of new APIs to attach BPF
programs to tracing entities such as {k,u}probes or tracepoints,
ii) improve specification of BTF-defined maps by eliminating the
need for data initialization for some of the members, iii) addition
of a high-level API for setting up and polling perf buffers for
BPF event output helpers, all from Andrii.
2) Add "prog run" subcommand to bpftool in order to test-run programs
through the kernel testing infrastructure of BPF, from Quentin.
3) Improve verifier for BPF sockaddr programs to support 8-byte stores
for user_ip6 and msg_src_ip6 members given clang tends to generate
such stores, from Stanislav.
4) Enable the new BPF JIT zero-extension optimization for further
riscv64 ALU ops, from Luke.
5) Fix a bpftool json JIT dump crash on powerpc, from Jiri.
6) Fix an AF_XDP race in generic XDP's receive path, from Ilya.
7) Various smaller fixes from Ilya, Yue and Arnd.
