Subject: [dpdk-stable] [PATCH v3] examples/ipsec-secgw: replace strncpy with strlcpy
Date: Wed, 9 May 2018 17:11:06 +0100 [thread overview]
Message-ID: <1525882266-2161-1-git-send-email-reshma.pattan@intel.com> (raw)
In-Reply-To: <1525881417-30440-1-git-send-email-reshma.pattan@intel.com>
Use strlcpy instead of strncpy.
Use strcpy where boundchecks on destination is not needed.
Fixes: 0d547ed037 ("examples/ipsec-secgw: support configuration file")
Fixes: 07b156199f ("examples/ipsec-secgw: fix configuration string termination")
Fixes: a1469c319f ("examples/ipsec-secgw: fix configuration parsing")
