Subject: [dpdk-dev] [PATCH v3] examples/ipsec-secgw: fix application crash.
Date: Mon, 16 Dec 2019 07:34:49 +0000	[thread overview]
Message-ID: <20191216073450.29390-1-savinay.dharmappa@intel.com> (raw)
In-Reply-To: <20191213114956.12062-1-savinay.dharmappa@intel.com>

if algo is NULL set the status to error and return. This change
prevent crashing of ipsec-secgw application when a specific
cipher/auth/aead algo are not supported by application.

Fixes: 0d547ed03717 ("examples/ipsec-secgw: support configuration file")
