Jesper Dangaard Brouer 817b89beb9 samples/bpf: all XDP samples should unload xdp/bpf prog on SIGTERM
It is common XDP practice to unload/deattach the XDP bpf program,
when the XDP sample program is Ctrl-C interrupted (SIGINT) or
killed (SIGTERM).

The samples/bpf programs xdp_redirect_cpu and xdp_rxq_info,
forgot to trap signal SIGTERM (which is the default signal used
by the kill command).

This was discovered by Red Hat QA, which automated scripts depend
on killing the XDP sample program after a timeout period.

Fixes: fad3917e36 ("samples/bpf: add cpumap sample program xdp_redirect_cpu")
Fixes: 0fca931a6f ("samples/bpf: program demonstrating access to xdp_rxq_info")

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
