      bluetooth: Fix use-before-initiailized var. · bf734843
      David S. Miller authored
      
      
      net/bluetooth/l2cap_core.c: In function ‘l2cap_recv_frame’:
      net/bluetooth/l2cap_core.c:3612:15: warning: ‘sk’ may be used uninitialized in this function
      net/bluetooth/l2cap_core.c:3612:15: note: ‘sk’ was declared here
      
      Actually the problem is in the inline function l2cap_data_channel(), we
      branch to the label 'done' which tests 'sk' before we set it to anything.
      
      Initialize it to NULL to fix this.

      be2net: Fixed a bug in be_cmd_get_regs(). · fe2a70ee
      Somnath Kotur authored
      
      
      Same WRB entry was being reused over different iterations of a
      loop while issuing non-embedded IOCTL requests.Fixed couple of minor bugs
      in this path as well.
      Re-factored code to alloc/free memory for DMA outside of loop

      bonding: move processing of recv handlers into handle_frame() · 3aba891d
      Jiri Pirko authored
      
      
      Since now when bonding uses rx_handler, all traffic going into bond
      device goes thru bond_handle_frame. So there's no need to go back into
      bonding code later via ptype handlers. This patch converts
      original ptype handlers into "bonding receive probes". These functions
      are called from bond_handle_frame and they are registered per-mode.
      
      Note that vlan packets are also handled because they are always untagged
      thanks to vlan_untag()
      
      Note that this also allows arpmon for eth-bond-bridge-vlan topology.

      The oops happens in dst_metrics_write_ptr()
      include/net/dst.h:124: return dst->ops->cow_metrics(dst, p);
      
      dst->ops->cow_metrics is NULL and causes the oops.

      cdc_ncm: fix short packet issue on some devices · 8c61d9d6
      Hans Petter Selasky authored
      
      
      The default maximum transmit length for NCM USB frames should be so
      that a short packet happens at the end if the device supports a length
      greater than the defined maximum. This is achieved by adding 4 bytes
      to the maximum length so that the existing logic can fit a short
      packet there.
