      ====================
      pull-request: bpf-next 2019-10-27
      
      The following pull-request contains BPF updates for your *net-next* tree.
      
      We've added 52 non-merge commits during the last 11 day(s) which contain
      a total of 65 files changed, 2604 insertions(+), 1100 deletions(-).
      
      The main changes are:
      
       1) Revolutionize BPF tracing by using in-kernel BTF to type check BPF
          assembly code. The work here teaches BPF verifier to recognize
          kfree_skb()'s first argument as 'struct sk_buff *' in tracepoints
          such that verifier allows direct use of bpf_skb_event_output() helper
          used in tc BPF et al (w/o probing memory access) that dumps skb data
          into perf ring buffer. Also add direct loads to probe memory in order
          to speed up/replace bpf_probe_read() calls, from Alexei Starovoitov.
      
       2) Big batch of changes to improve libbpf and BPF kselftests. Besides
          others: generalization of libbpf's CO-RE relocation support to now
          also include field existence relocations, revamp the BPF kselftest
          Makefile to add test runner concept allowing to exercise various
          ways to build BPF programs, and teach bpf_object__open() and friends
          to automatically derive BPF program type/expected attach type from
          section names to ease their use, from Andrii Nakryiko.
      
       3) Fix deadlock in stackmap's build-id lookup on rq_lock(), from Song Liu.
      
       4) Allow to read BTF as raw data from bpftool. Most notable use case
          is to dump /sys/kernel/btf/vmlinux through this, from Jiri Olsa.
      
       5) Use bpf_redirect_map() helper in libbpf's AF_XDP helper prog which
          manages to improve "rx_drop" performance by ~4%., from Björn Töpel.
      
       6) Fix to restore the flow dissector after reattach BPF test and also
          fix error handling in bpf_helper_defs.h generation, from Jakub Sitnicki.
      
       7) Improve verifier's BTF ctx access for use outside of raw_tp, from
          Martin KaFai Lau.
      
       8) Improve documentation for AF_XDP with new sections and to reflect
          latest features, from Magnus Karlsson.
      
       9) Add back 'version' section parsing to libbpf for old kernels, from
          John Fastabend.
      
      10) Fix strncat bounds error in libbpf's libbpf_prog_type_by_name(),
          from KP Singh.
      
      11) Turn on -mattr=+alu32 in LLVM by default for BPF kselftests in order
          to improve insn coverage for built BPF progs, from Yonghong Song.
      
      12) Misc minor cleanups and fixes, from various others.

      3) Move ipset function definition from header to source file.
      
      4) Move ip_set_put_flags() to source, export it as a symbol, remove
         inline.
      
      5) Move range_to_mask() to the source file where this is used.
      
      6) Move ip_set_get_ip_port() to the source file where this is used.
      
      * IPVS selftests and netns improvements:
      
      7) Two patches to speedup ipvs netns dismantle, from Haishuang Yan.

      net: aquantia: ptp followup fixes
      
      Here are two sparse warnings, third patch is a fix for
      scaled_ppm_to_ppb missing. Eventually I reworked this
      to exclude ptp module from build. Please consider it instead
      of this patch: https://patchwork.ozlabs.org/patch/1184171/

      net: aquantia: disable ptp object build if no config · 7873ee26
      Igor Russkikh authored
      We do disable aq_ptp module build using inline
      stubs when CONFIG_PTP_1588_CLOCK is not declared.
      
      This reduces module size and removes unnecessary code.
