      bpf: fix up uapi helper description and sync bpf header with tools · 0bd72117
      Daniel Borkmann authored
      
      
      Minor markup fixup from bpf-next into net-next merge in the BPF helper
      description of bpf_sk_lookup_tcp() and bpf_sk_lookup_udp(). Also sync
      up the copy of bpf.h from tooling infrastructure.

      ====================
      pull-request: bpf-next 2018-12-11
      
      The following pull-request contains BPF updates for your *net-next* tree.
      
      It has three minor merge conflicts, resolutions:
      
      1) tools/testing/selftests/bpf/test_verifier.c
      
       Take first chunk with alignment_prevented_execution.
      
      2) net/core/filter.c
      
        [...]
        case bpf_ctx_range_ptr(struct __sk_buff, flow_keys):
        case bpf_ctx_range(struct __sk_buff, wire_len):
              return false;
        [...]
      
      3) include/uapi/linux/bpf.h
      
        Take the second chunk for the two cases each.
      
      The main changes are:
      
      1) Add support for BPF line info via BTF and extend libbpf as well
         as bpftool's program dump to annotate output with BPF C code to
         facilitate debugging and introspection, from Martin.
      
      2) Add support for BPF_ALU | BPF_ARSH | BPF_{K,X} in interpreter
         and all JIT backends, from Jiong.
      
      3) Improve BPF test coverage on archs with no efficient unaligned
         access by adding an "any alignment" flag to the BPF program load
         to forcefully disable verifier alignment checks, from David.
      
      4) Add a new bpf_prog_test_run_xattr() API to libbpf which allows for
         proper use of BPF_PROG_TEST_RUN with data_out, from Lorenz.
      
      5) Extend tc BPF programs to use a new __sk_buff field called wire_len
         for more accurate accounting of packets going to wire, from Petar.
      
      6) Improve bpftool to allow dumping the trace pipe from it and add
         several improvements in bash completion and map/prog dump,
         from Quentin.
      
      7) Optimize arm64 BPF JIT to always emit movn/movk/movk sequence for
         kernel addresses and add a dedicated BPF JIT backend allocator,
         from Ard.
      
      8) Add a BPF helper function for IR remotes to report mouse movements,
         from Sean.
      
      9) Various cleanups in BPF prog dump e.g. to make UAPI bpf_prog_info
         member naming consistent with existing conventions, from Yonghong
         and Song.
      
      10) Misc cleanups and improvements in allowing to pass interface name
          via cmdline for xdp1 BPF example, from Matteo.
      
      11) Fix a potential segfault in BPF sample loader's kprobes handling,
          from Daniel T.
      
      12) Fix SPDX license in libbpf's README.rst, from Andrey.

      neighbor: gc_list changes should be protected by table lock · 8cc196d6
      David Ahern authored
      Adding and removing neighbor entries to / from the gc_list need to be
      done while holding the table lock; a couple of places were missed in the
      original patch.
      
      Move the list_add_tail in neigh_alloc to ___neigh_create where the lock
      is already obtained. Since neighbor entries should rarely be moved
      to/from PERMANENT state, add lock/unlock around the gc_list changes in
      neigh_change_state rather than extending the lock hold around all
      neighbor updates.
      
      Fixes: 58956317
      
       ("neighbor: Improve garbage collection")

      ====================
      mlx5e-updates-2018-12-10 (gre)
      
      This patch set adds GRE offloading support to Mellanox ethernet driver.
      
      Patches 1-5 replace the existing egdev mechanism with the new TC indirect
      block binds mechanism that was introduced by Netronome:
      7f76fa36
      
       ("net: sched: register callbacks for indirect tc block binds")
      
      Patches 6-9 add GRE offloading support along with some required
      refactoring work.
      
      Patch 10, Add netif_is_gretap()/netif_is_ip6gretap()
       - Changed the is_gretap_dev and is_ip6gretap_dev logic from structure
         comparison to string comparison of the rtnl_link_ops kind field.
      
      Patch 11, add GRE offloading support to mlx5.
      
      Patch 12 removes the egdev mechanism from TC as it is no longer used by
      any of the drivers.
