Po-Hsu Lin fbbcd769c8 selftests: net: use BASH for bareudp testing 
[ Upstream commit 9311e9540a ]

In bareudp.sh, this script uses /bin/sh and it will load another lib.sh
BASH script at the very beginning.

But on some operating systems like Ubuntu, /bin/sh is actually pointed to
DASH, thus it will try to run BASH commands with DASH and consequently
leads to syntax issues:
  # ./bareudp.sh: 4: ./lib.sh: Bad substitution
  # ./bareudp.sh: 5: ./lib.sh: source: not found
  # ./bareudp.sh: 24: ./lib.sh: Syntax error: "(" unexpected

Fix this by explicitly using BASH for bareudp.sh. This fixes test
execution failures on systems where /bin/sh is not BASH.

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.
