Ilya Maximets f583bac0da net: openvswitch: fix skb leak on flow key update failure during recirculation 
[ Upstream commit e1cf066244 ]

do_execute_actions() returns right away when execute_recirc() fails on
the last action as it assumes this function always takes ownership of
the skb when 'last' is true.  But when the flow key update fails, the
function doesn't free the skb and it ends up leaked.

This is a very unlikely scenario as it requires the packet to become
unparseable by applying a set of actions on a previously parseable skb,
but should be fixed nevertheless.

Reported by Sashiko.

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.
