      bpf: lpm_trie: check left child of last leftmost node for NULL · da2577fd
      Jonathan Lemon authored
      If the leftmost parent node of the tree has does not have a child
      on the left side, then trie_get_next_key (and bpftool map dump) will
      not look at the child on the right.  This leads to the traversal
      missing elements.
      
      Lookup is not affected.
      
      Update selftest to handle this case.
      
      Reproducer:
      
       bpftool map create /sys/fs/bpf/lpm type lpm_trie key 6 \
           value 1 entries 256 name test_lpm flags 1
       bpftool map update pinned /sys/fs/bpf/lpm key  8 0 0 0  0   0 value 1
       bpftool map update pinned /sys/fs/bpf/lpm key 16 0 0 0  0 128 value 2
       bpftool map dump   pinned /sys/fs/bpf/lpm
      
      Returns only 1 element. (2 expected)

      nfp: ensure skb network header is set for packet redirect · dce5cccc
      John Hurley authored
      Packets received at the NFP driver may be redirected to egress of another
      netdev (e.g. in the case of OvS internal ports). On the egress path, some
      processes, like TC egress hooks, may expect the network header offset
      field in the skb to be correctly set. If this is not the case there is
      potential for abnormal behaviour and even the triggering of BUG() calls.
      
      Set the skb network header field before the mac header pull when doing a
      packet redirect.

      tcp: fix undo spurious SYNACK in passive Fast Open · fcc2202a
      Yuchung Cheng authored
      Commit 794200d6 ("tcp: undo cwnd on Fast Open spurious SYNACK
      retransmit") may cause tcp_fastretrans_alert() to warn about pending
      retransmission in Open state. This is triggered when the Fast Open
      server both sends data and has spurious SYNACK retransmission during
      the handshake, and the data packets were lost or reordered.
      
      The root cause is a bit complicated:
      
      (1) Upon receiving SYN-data: a full socket is created with
          snd_una = ISN + 1 by tcp_create_openreq_child()
      
      (2) On SYNACK timeout the server/sender enters CA_Loss state.
      
      (3) Upon receiving the final ACK to complete the handshake, sender
          does not mark FLAG_SND_UNA_ADVANCED since (1)
      
          Sender then calls tcp_process_loss since state is CA_loss by (2)
      
      (4) tcp_process_loss() does not invoke undo operations but instead
          mark REXMIT_LOST to force retransmission
      
      (5) tcp_rcv_synrecv_state_fastopen() calls tcp_try_undo_loss(). It
          changes state to CA_Open but has positive tp->retrans_out
      
      (6) Next ACK triggers the WARN_ON in tcp_fastretrans_alert()
      
      The step that goes wrong is (4) where the undo operation should
      have been invoked because the ACK successfully acknowledged the
      SYN sequence. This fixes that by specifically checking undo
      when the SYN-ACK sequence is acknowledged. Then after
      tcp_process_loss() the state would be further adjusted based
      in tcp_fastretrans_alert() to avoid triggering the warning in (6).

      ====================
      ibmvnic: Fixes for device reset handling
      
      This series contains three unrelated fixes to issues seen during
      device resets. The first patch fixes an error when the driver requests
      to deactivate the link of an uninitialized device, resulting in a
      failure to reset. Next, a patch to fix multicast transmission
      failures seen after a driver reset. The final patch fixes mishandling
      of memory allocation failures during device initialization, which
      caused a kernel oops.

      pull-request: bpf 2019-06-07
      
      The following pull-request contains BPF updates for your *net* tree.
      
      The main changes are:
      
      1) Fix several bugs in riscv64 JIT code emission which forgot to clear high
         32-bits for alu32 ops, from Björn and Luke with selftests covering all
         relevant BPF alu ops from Björn and Jiong.
      
      2) Two fixes for UDP BPF reuseport that avoid calling the program in case of
         __udp6_lib_err and UDP GRO which broke reuseport_select_sock() assumption
         that skb->data is pointing to transport header, from Martin.
      
      3) Two fixes for BPF sockmap: a use-after-free from sleep in psock's backlog
         workqueue, and a missing restore of sk_write_space when psock gets dropped,
         from Jakub and John.
      
      4) Fix unconnected UDP sendmsg hook API which is insufficient as-is since it
         breaks standard applications like DNS if reverse NAT is not performed upon
         receive, from Daniel.
      
      5) Fix an out-of-bounds read in __bpf_skc_lookup which in case of AF_INET6
         fails to verify that the length of the tuple is long enough, from Lorenz.
      
      6) Fix libbpf's libbpf__probe_raw_btf to return an fd instead of 0/1 (for
         {un,}successful probe) as that is expected to be propagated as an fd to
         load_sk_storage_btf() and thus closing the wrong descriptor otherwise,
         from Michal.
      
      7) Fix bpftool's JSON output for the case when a lookup fails, from Krzesimir.
      
      8) Minor misc fixes in docs, samples and selftests, from various others.

      However, the mlx5e_detach function was not updated accordingly, and it
      still tries to detach a non-existing netdev, causing a kernel crash.

      net/mlx5e: Replace reciprocal_scale in TX select queue function · 57c70d87
      Shay Agroskin authored
      The TX queue index returned by the fallback function ranges
      between [0,NUM CHANNELS - 1] if QoS isn't set and
      [0, (NUM CHANNELS)*(NUM TCs) -1] otherwise.
      
      Our HW uses different TC mapping than the fallback function
      (which is denoted as 'up', user priority) so we only need to extract
      a channel number out of the returned value.
      
      Since (NUM CHANNELS)*(NUM TCs) is a relatively small number, using
      reciprocal scale almost always returns zero.
      We instead access the 'txq2sq' table to extract the sq (and with it the
      channel number) associated with the tx queue, thus getting
      a more evenly distributed channel number.
      
      Perf:
      
      Rx/Tx side with Intel(R) Xeon(R) Silver 4108 CPU @ 1.80GHz and ConnectX-5.
      Used 'iperf' UDP traffic, 10 threads, and priority 5.
      
      Before:	0.566Mpps
      After:	 2.37Mpps
      
      As expected, releasing the existing bottleneck of steering all traffic
      to TX queue zero significantly improves transmission rates.

      "Pointers printed without a specifier extension (i.e unadorned %p) are
      hashed to prevent leaking information about the kernel memory layout. This
      has the added benefit of providing a unique identifier. On 64-bit machines
      the first 32 bits are zeroed. The kernel will print ``(ptrval)`` until it
      gathers enough entropy."
      
      Instead of passing %pK, which can print the correct address, simply
      remove the entire message as it is not really that useful.

      Eugen Hristev authored
      During frame reception while the MCAN is in Error Passive state and the
      Receive Error Counter has thevalue MCAN_ECR.REC = 127, it may happen
      that MCAN_IR.MRAF is set although there was no Message RAM access
      failure. If MCAN_IR.MRAF is enabled, an interrupt to the Host CPU is
      generated.
      
      Work around:
      The Message RAM Access Failure interrupt routine needs to check whether
      
          MCAN_ECR.RP = '1' and MCAN_ECR.REC = '127'.

      Reproducibility: If 2 devices with m_can are connected back to back,
      configuring different bitrate on them will lead to interrupt storm on
      the receiving side, with error "Message RAM access failure occurred".
      Another way is to have a bad hardware connection. Bad wire connection
      can lead to this issue as well.
      
      This patch fixes the issue according to provided workaround.

      Anssi Hannula authored
      Commit 9e5f1b27 ("can: xilinx_can: add support for Xilinx CAN FD
      core") added a new can_bittiming_const structure for CAN FD cores that
      support larger values for tseg1, tseg2, and sjw than previous Xilinx CAN
      cores, but the commit did not actually take that into use.
      
      Fix that.
      
      Tested with CAN FD core on a ZynqMP board.

      can: flexcan: fix timeout when set small bitrate · 247e5356
      Joakim Zhang authored
      Current we can meet timeout issue when setting a small bitrate like
      10000 as follows on i.MX6UL EVK board (ipg clock = 66MHZ, per clock =
      30MHZ):
      
      | root@imx6ul7d:~# ip link set can0 up type can bitrate 10000
      
      A link change request failed with some changes committed already.
      Interface can0 may have been left with an inconsistent configuration,
      please check.
      
      | RTNETLINK answers: Connection timed out
      
      It is caused by calling of flexcan_chip_unfreeze() timeout.
      
      Originally the code is using usleep_range(10, 20) for unfreeze
      operation, but the patch (8badd65e can: flexcan: avoid calling
      usleep_range from interrupt context) changed it into udelay(10) which is
      only a half delay of before, there're also some other delay changes.
      
      After double to FLEXCAN_TIMEOUT_US to 100 can fix the issue.
      
      Meanwhile, Rasmus Villemoes reported that even with a timeout of 100,
      flexcan_probe() fails on the MPC8309, which requires a value of at least
      140 to work reliably. 250 works for everyone.

      * fix out of bounds compiler warning
      
      * fix rssi handling to get 4x more throughput
      
      * avoid circular locking
      
      rsi
      
      * fix unitilised data warning, these are hopefully the last ones so
        that the warning can be enabled by default
      
      mwifiex
      
      * fix buffer overflows
      
      iwlwifi
