xenial.

Title:
  Gunicorn traceback when downloading “not modified” page

Status in gunicorn package in Ubuntu:
  Fix Released

Bug description:
  Hello,

  We encounter tracebacks in gunicorn-error.log when a client download a
  “not modified” page:

      gunicorn-error.log <==
      2015-06-16 11:39:00 [5565] [ERROR] Socket error processing request.
      Traceback (most recent call last):
        File "/usr/lib/python2.7/dist-packages/gunicorn/workers/async.py", line 42, in handle
          req = six.next(parser)
        File "/usr/lib/python2.7/dist-packages/gunicorn/http/parser.py", line 39, in __next__
          self.mesg = self.mesg_class(self.cfg, self.unreader, self.req_count)
        File "/usr/lib/python2.7/dist-packages/gunicorn/http/message.py", line 152, in __init__
          super(Request, self).__init__(cfg, unreader)
        File "/usr/lib/python2.7/dist-packages/gunicorn/http/message.py", line 49, in __init__
          unused = self.parse(self.unreader)
        File "/usr/lib/python2.7/dist-packages/gunicorn/http/message.py", line 164, in parse
          self.get_data(unreader, buf, stop=True)
        File "/usr/lib/python2.7/dist-packages/gunicorn/http/message.py", line 155, in get_data
          data = unreader.read()
        File "/usr/lib/python2.7/dist-packages/gunicorn/http/unreader.py", line 38, in read
          d = self.chunk()
        File "/usr/lib/python2.7/dist-packages/gunicorn/http/unreader.py", line 65, in chunk
          return self.sock.recv(self.mxchunk)
        File "/usr/lib/python2.7/dist-packages/eventlet/greenio.py", line 251, in recv
          return fd.recv(buflen, flags)
        File "/usr/lib/python2.7/socket.py", line 170, in _dummy
          raise error(EBADF, 'Bad file descriptor')
      error: [Errno 9] Bad file descriptor

  This problem is reported and fixed upstream
  (https://github.com/benoitc/gunicorn/issues/630).

  Is it possible to backport the patch?

  Regards.
