Ilya Maximets fee500c335 net: openvswitch: don't send internal clone attribute to the userspace.
[ Upstream commit 3f2a3050b4a3e7f32fc0ea3c9b0183090ae00522 ]

'OVS_CLONE_ATTR_EXEC' is an internal attribute that is used for
performance optimization inside the kernel.  It's added by the kernel
while parsing user-provided actions and should not be sent during the
flow dump as it's not part of the uAPI.

The issue doesn't cause any significant problems to the ovs-vswitchd
process, because reported actions are not really used in the
application lifecycle and only supposed to be shown to a human via
ovs-dpctl flow dump.  However, the action list is still incorrect
and causes the following error if the user wants to look at the
datapath flows:

  # ovs-dpctl add-dp system@ovs-system
  # ovs-dpctl add-flow "<flow match>" "clone(ct(commit),0)"
  # ovs-dpctl dump-flows
  <flow match>, packets:0, bytes:0, used:never,
    actions:clone(bad length 4, expected -1 for: action0(01 00 00 00),
                  ct(commit),0)

With the fix:

  # ovs-dpctl dump-flows
  <flow match>, packets:0, bytes:0, used:never,
    actions:clone(ct(commit),0)

Additionally fixed an incorrect attribute name in the comment.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
