Subject: [dpdk-dev] [PATCH v2] examples/ip_pipeline: fix buffer not null terminated
Date: Tue, 17 Apr 2018 17:39:53 +0100	[thread overview]
Message-ID: <20180417163953.72821-1-jasvinder.singh@intel.com> (raw)
In-Reply-To: <20180417132825.148429-1-jasvinder.singh@intel.com>

The destination string may not have a null termination if
the source string's length is equal to the sizeof(pipeline->name).

Fix by replacing strncpy with strlcpy that guarantees NULL-termination.

Coverty issue: 272606
Fixes: d75c371e9b46 ("examples/ip_pipeline: add pipeline object")
