Subject: [dpdk-dev] [PATCH] cmdline: avoid garbage in unused fields of parsed result
Date: Sat, 20 Jan 2018 11:26:31 +0800 [thread overview]
Message-ID: <20180120032631.132978-1-xuemingl@mellanox.com> (raw)
The result buffer was not initialized before parsing, inducing garbage
in unused fields or padding of the parsed structure.
Initialize the result buffer each time before parsing.
Fixes: af75078fece3 ("first public release")
