This builds up on the existing socket cookie test which checks whether the bpf_get_socket_cookie helpers provide the same value in cgroup/connect6 and sockops programs for a socket created by the userspace part of the test. Instead of having an update_cookie sockops program tag a socket local storage with 0xFF, this uses both an update_cookie_sockops program and an update_cookie_tracing program which succesively tag the socket with 0x0F and then 0xF0.

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.
