Description

• When a transparent proxy application was running and the number of established
  connections on the computer exceeded one million, unrelated processes, such as
  curl or ssh, were unable to bind to a local IP on the box to initiate a
  connection. The provided patch fixes the cooperation of the
  REUSEADDR/NOREUSEADDR socket option, and thus prevents the local port from being
  exhausted. As a result, the aforementioned bug no longer occurs in the described
  scenario. (BZ#1333571)

• Previously, packets including the Common IP Security Option (CIPSO) label tag
  type 5 with certain category ranges were not read correctly. As a consequence,
  these packets were interpreted with the fallback security label. The provided
  patch fixes the netlbl_secattr_catmap_setrng() function, and thus fixes this
  bug. (BZ#1333579)

• When hot removing or adding devices from a RAID1 array, the raid1d
  daemon could deadlock and become unresponsive in the freeze_array() function.
  The provided patch includes bio_end_io_list writes in the nr_queued variable to
  prevent the aforementioned hang from occurring. (BZ#1333576)
