Subject: [dpdk-stable] [PATCH] tests/cmdline: fix memory leaks
Date: Mon, 16 Aug 2021 08:05:13 -0400
Message-ID: <20210816120512.12224-1-ohilyard@iol.unh.edu> (raw)
In-Reply-To: <CAATJJ0Lxjm8uaF1YWPk9ejW+U3=SLwWLwBx=7h2TUrGAjXORKg@mail.gmail.com>

From: Owen Hilyard <ohilyard@iol.unh.edu>

[ upstream commit ca7204b921c2f328ab1222772af40922970e7c4b ]

Fixes for a few memory leaks in the cmdline_autotest unit test.

All of the leaks were related to not freeing the commandline struct
after testing had completed.

Fixes: dbb860e03e ("cmdline: tests")
