Subject: [dpdk-stable] [PATCH v3 1/2] test/mempool: fix heap buffer overflow
Date: Tue, 27 Apr 2021 15:56:45 +0200
Message-ID: <20210427135646.871-1-olivier.matz@6wind.com> (raw)
In-Reply-To: <20210413200513.330399-1-wenwux.ma@intel.com>

The function rte_pktmbuf_init() expects that the mempool private area is
large enough and was previously initialized by rte_pktmbuf_pool_init(),
which is not the case.

This causes the function rte_pktmbuf_priv_size() to return an
unpredictable value, and this value is used as a size in a memset.

Replace the mempool object initializer by my_obj_init(), which does not
have this constraint, and fits the needs for this test.

Fixes: 923ceaeac140 ("test/mempool: add unit test cases")
Cc: stable@dpdk.org
