Subject: [dpdk-dev] [PATCH v2] app/test: fix possible overflow using strlcat
Date: Mon, 18 Mar 2019 12:36:36 +0000	[thread overview]
Message-ID: <1552912596-2776-1-git-send-email-tallurix.chaitanya.babu@intel.com> (raw)
In-Reply-To: <1552569280-27944-1-git-send-email-tallurix.chaitanya.babu@intel.com>

strcat does not check the destination length and there might be
chances of string overflow so instead of strcat, strlcat is used.

Fixes: 6f4eec2565 ("test/crypto: enhance scheduler unit tests")
Cc: stable@dpdk.org
