[ Upstream commit3f2a3050b4] '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.
