Pass a dscp_t variable to ip_route_input_rcu(), instead of a plain u8,
to prevent accidental setting of ECN bits in ->flowi4_tos.
Callers of ip_route_input_rcu() to consider are:
* ip_route_input_noref(), which already has a dscp_t variable to pass
as parameter. We just need to remove the inet_dscp_to_dsfield()
conversion.
* inet_rtm_getroute(), which receives a u8 from user space and needs
to convert it with inet_dsfield_to_dscp().

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 reStructuredText 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.
