[ Upstream commit 189c9b1e94539b11c80636bc13e9cf47529e7bba ] skb->csum is updated incorrectly, when manipulation for NF_NAT_MANIP_SRC\DST is done on IPV6 packet. Fix: There is no need to update skb->csum in inet_proto_csum_replace16(), because update in two fields a.) IPv6 src/dst address and b.) L4 header checksum cancels each other for skb->csum calculation. Whereas inet_proto_csum_replace4 function needs to update skb->csum, because update in 3 fields a.) IPv4 src/dst address, b.) IPv4 Header checksum and c.) L4 header checksum results in same diff as L4 Header checksum for skb->csum calculation.

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.
