Jakub Sitnicki 44d28be2b8 selftests/bpf: Tests for sockmap/sockhash holding listening sockets
Now that SOCKMAP and SOCKHASH map types can store listening sockets,
user-space and BPF API is open to a new set of potential pitfalls.

Exercise the map operations, with extra attention to code paths susceptible
to races between map ops and socket cloning, and BPF helpers that work with
SOCKMAP/SOCKHASH to gain confidence that all works as expected.

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.
