Aaron Conole 894347d4d2 openvswitch: always update flow key after nat 
[ Upstream commit 60b44ca6bd ]

During NAT, a tuple collision may occur.  When this happens, openvswitch
will make a second pass through NAT which will perform additional packet
modification.  This will update the skb data, but not the flow key that
OVS uses.  This means that future flow lookups, and packet matches will
have incorrect data.  This has been supported since
5d50aa83e2 ("openvswitch: support asymmetric conntrack").

That commit failed to properly update the sw_flow_key attributes, since
it only called the ovs_ct_nat_update_key once, rather than each time
ovs_ct_nat_execute was called.  As these two operations are linked, the
ovs_ct_nat_execute() function should always make sure that the
sw_flow_key is updated after a successful call through NAT infrastructure.

README 

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.
