      ====================
      net: More extack messages
      
      Add more extack messages for several link create errors (e.g., invalid
      number of queues, unknown link kind) and invalid metrics argument.

      rtnetlink: Add more extack messages to rtnl_newlink · 68d57f3b
      David Ahern authored
      Add extack arg to the nla_parse_nested calls in rtnl_newlink, and
      add messages for unknown device type and link network namespace id.
      In particular, it improves the failure message when the wrong link
      type is used. From
          $ ip li add bond1 type bonding
          RTNETLINK answers: Operation not supported
      to
          $ ip li add bond1 type bonding
          Error: Unknown device type.
      
      (The module name is bonding but the link type is bond.)

      ipv6: gro: do not use slow memcmp() in ipv6_gro_receive() · 0b215b97
      Eric Dumazet authored
      ipv6_gro_receive() compares 34 bytes using slow memcmp(),
      while handcoding with a couple of ipv6_addr_equal() is much faster.
      
      Before this patch, "perf top -e cycles:pp -C <cpu>" would
      see memcmp() using ~10% of cpu cycles on a 40Gbit NIC
      receiving IPv6 TCP traffic.

      ISDN: eicon: Remove driver · a8d62195
      Olof Johansson authored
      I started looking at the history of this driver, and last time the
      maintainer was active on the mailing list was when discussing how to
      remove it. This was in 2012:
      
      https://lore.kernel.org/lkml/4F4DE175.30002@melware.de/
      
      It looks to me like this has in practice been an orphan for quite a while.
      It's throwing warnings about stack size in a function that is in dire
      need of refactoring, and it's probably a case of "it's time to call it".

        The reason this wasn't detected in our tests is that the only way this
        would transpire is when a kprobe event with a symbol offset is
        attached to a function that belongs to a module that isn't loaded yet.
        When the kprobe trace event is added, the offset would be truncated
        after it was parsed, and when the module is loaded, it would use the
        symbol without the offset (as the nul character added by the parsing
        would not be replaced with the original character)"

      ARM: 8809/1: proc-v7: fix Thumb annotation of cpu_v7_hvc_switch_mm · 6282e916
      Ard Biesheuvel authored
      Due to what appears to be a copy/paste error, the opening ENTRY()
      of cpu_v7_hvc_switch_mm() lacks a matching ENDPROC(), and instead,
      the one for cpu_v7_smc_switch_mm() is duplicated.
      
      Given that it is ENDPROC() that emits the Thumb annotation, the
      cpu_v7_hvc_switch_mm() routine will be called in ARM mode on a
      Thumb2 kernel, resulting in the following splat:

          comes with preparation patch to add nf_{tcp,udp,...}_pernet()
          helper.
      
      12) Allow ebtables table nat to be of filter type via nft_compat.
          From Florian Westphal.

      rtnetlink: restore handling of dumpit return value in rtnl_dump_all() · 5e1acb4a
      Alexey Kodanev authored
      For non-zero return from dumpit() we should break the loop
      in rtnl_dump_all() and return the result. Otherwise, e.g.,
      we could get the memory leak in inet6_dump_fib() [1]. The
      pointer to the allocated struct fib6_walker there (saved
      in cb->args) can be lost, reset on the next iteration.
      
      Fix it by partially restoring the previous behavior before
      commit c63586dc ("net: rtnl_dump_all needs to propagate
      error from dumpit function"). The returned error from
      dumpit() is still passed further.

      pull-request: bpf 2018-11-03
      
      The following pull-request contains BPF updates for your *net* tree.
      
      The main changes are:
      
      1) Fix BPF prog kallsyms and bpf_prog_get_info_by_fd() jited address export
         to not use page start but actual start instead to work correctly with
         profiling e.g. finding hot instructions from stack traces. Also fix latter
         with regards to dumping address and jited len for !multi prog, from Song.
      
      2) Fix bpf_prog_get_info_by_fd() for !root to zero info.nr_jited_func_lens
         instead of leaving the user provided length, from Daniel.

      The CPU policer used to police packets being trapped via a local route
      (IP2ME) was incorrectly configured to police based on bytes per second
      instead of packets per second.
      
      Change the policer to police based on packets per second and avoid
      packet loss under certain circumstances.

      openvswitch: fix linking without CONFIG_NF_CONNTRACK_LABELS · a277d516
      Arnd Bergmann authored
      When CONFIG_CC_OPTIMIZE_FOR_DEBUGGING is enabled, the compiler
      fails to optimize out a dead code path, which leads to a link failure:
      
      net/openvswitch/conntrack.o: In function `ovs_ct_set_labels':
      conntrack.c:(.text+0x2e60): undefined reference to `nf_connlabels_replace'
      
      In this configuration, we can take a shortcut, and completely
      remove the contrack label code. This may also help the regular
      optimization.

      When an error is returned by qed_mcp_get_transceiver_data(), we
      should propagate that to the caller of qed_mcp_trans_speed_mask()
      rather than continuing with uninitialized data.
