Initialize the ip cookie tos field when initializing the cookie, in ipcm_init_sk. The existing code inverts the standard pattern for initializing cookie fields. Default is to initialize the field from the sk, then possibly overwrite that when parsing cmsgs (the unlikely case). This field inverts that, setting the field to an illegal value and after cmsg parsing checking whether the value is still illegal and thus should be overridden. Be careful to always apply mask INET_DSCP_MASK, as before.

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.
