David Howells 39cb9faa5d rxrpc: Enable IPv6 checksums on transport socket
AF_RXRPC doesn't currently enable IPv6 UDP Tx checksums on the transport
socket it opens and the checksums in the packets it generates end up 0.

It probably should also enable IPv6 UDP Rx checksums and IPv4 UDP
checksums.  The latter only seem to be applied if the socket family is
AF_INET and don't seem to apply if it's AF_INET6.  IPv4 packets from an
IPv6 socket seem to have checksums anyway.

What seems to have happened is that the inet_inv_convert_csum() call didn't
get converted to the appropriate udp_port_cfg parameters - and
udp_sock_create() disables checksums unless explicitly told not too.

Fix this by enabling the three udp_port_cfg checksum options.

Fixes: 1a9b86c9fd ("rxrpc: use udp tunnel APIs instead of open code in rxrpc_open_socket")

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.
