Subject: [dpdk-dev] [PATCH 05/10] app/test: add null pointer check of memory allocation
Date: Mon, 19 Apr 2021 21:34:44 +0800	[thread overview]
Message-ID: <1618839289-33224-6-git-send-email-humin29@huawei.com> (raw)
In-Reply-To: <1618839289-33224-1-git-send-email-humin29@huawei.com>

From: HongBo Zheng <zhenghongbo3@huawei.com>

The rte_zmalloc is called in test_crc_calc without null pointer
check. This patch adds null pointer checks on return value of
rte_zmalloc.

Fixes: 9c77b848b1c1 ("test: add CRC computation")
