Subject: [dpdk-dev] [v2] test/mempool: fix heap buffer overflow
Date: Tue, 13 Apr 2021 20:05:13 +0000	[thread overview]
Message-ID: <20210413200513.330399-1-wenwux.ma@intel.com> (raw)
In-Reply-To: <20210331210557.4919-1-wenwux.ma@intel.com>

Amount of allocated memory was not enough for mempool
which cause buffer overflow when access fields of mempool
private structure in the rte_pktmbuf_priv_size function.

Fixes: 923ceaeac140 ("test/mempool: add unit test cases")
