      cdc_ether: Ignore bogus union descriptor for RNDIS devices · 6eddcb4c
      Bjørn Mork authored
      Some RNDIS devices include a bogus CDC Union descriptor pointing
      to non-existing interfaces.  The RNDIS code is already prepared
      to handle devices without a CDC Union descriptor by hardwiring
      the driver to use interfaces 0 and 1, which is correct for the
      devices with the bogus descriptor as well. So we can reuse the
      existing workaround.

      bnx2x: bug fix when loading after SAN boot · 24f06716
      Ariel Elior authored
      This is a bug fix for an "interface fails to load" issue.
      The issue occurs when bnx2x driver loads after UNDI driver was previously
      loaded over the chip. In such a scenario the UNDI driver is loaded and operates
      in the pre-boot kernel, within its own specific host memory address range.
      When the pre-boot stage is complete, the real kernel is loaded, in a new and
      distinct host memory address range. The transition from pre-boot stage to boot
      is asynchronous from UNDI point of view.
      
      A race condition occurs when UNDI driver triggers a DMAE transaction to valid
      host addresses in the pre-boot stage, when control is diverted to the real
      kernel. This results in access to illegal addresses by our HW as the addresses
      which were valid in the preboot stage are no longer considered valid.
      Specifically, the 'was_error' bit in the pci glue of our device is set. This
      causes all following pci transactions from chip to host to timeout (in
      accordance to the pci spec).

      igb, ixgbe: netdev_tx_reset_queue incorrectly called from tx init path · dad8a3b3
      John Fastabend authored
      igb and ixgbe incorrectly call netdev_tx_reset_queue() from
      i{gb|xgbe}_clean_tx_ring() this sort of works in most cases except
      when the number of real tx queues changes. When the number of real
      tx queues changes netdev_tx_reset_queue() only gets called on the
      new number of queues so when we reduce the number of queues we risk
      triggering the watchdog timer and repeated device resets.
      
      So this is not only a cosmetic issue but causes real bugs. For
      example enabling/disabling DCB or FCoE in ixgbe will trigger this.

      efivars: Improve variable validation · 54b3a4d3
      Matthew Garrett authored
      Ben Hutchings pointed out that the validation in efivars was inadequate -
      most obviously, an entry with size 0 would server as a DoS against the
      kernel. Improve this based on his suggestions.

             Socket memory cgroup code (I never should have applied those
             patches, grumble...) made erroneous changes to
             sk_sockets_allocated_read_positive().  It was changed to
             use percpu_counter_sum_positive (which requires BH disabling)
             instead of percpu_counter_read_positive (which does not).
             Revert back to avoid crashes and lockdep warnings.
      
             Adjust the default tcp_adv_win_scale and tcp_rmem[2] values
