Sven Auhagen ff758e8a77 netfilter: flowtable: fix tcp and udp header checksum update
[ Upstream commit 8d6bca156e47d68551750a384b3ff49384c67be3 ]

When updating the tcp or udp header checksum on port nat the function
inet_proto_csum_replace2 with the last parameter pseudohdr as true.
This leads to an error in the case that GRO is used and packets are
split up in GSO. The tcp or udp checksum of all packets is incorrect.

The error is probably masked due to the fact the most network driver
implement tcp/udp checksum offloading. It also only happens when GRO is
applied and not on single packets.

The error is most visible when using a pppoe connection which is not
triggering the tcp/udp checksum offload.

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.
