Subject: [dpdk-stable] [PATCH] app/proc-info: fix string copying to use strlcpy
Date: Thu, 26 Sep 2019 16:11:59 +0100 [thread overview]
Message-ID: <20190926151159.19256-1-ciara.power@intel.com> (raw)
Replaced strncpy and strcpy with strlcpy.
Also replaced snprintf with strlcpy where applicable.
Using strlcpy is safe practice when copying strings,
as it will include a null terminator.

Fixes: 2deb6b5246d7 ("app/procinfo: add collectd format and host id")
Fixes: 8a37f37fc243 ("app/procinfo: add --show-port")
