-----Original Message----- From: dev <[email protected]> On Behalf Of Wenwu Ma Sent: Thursday, April 1, 2021 5:06 AM To: [email protected]; [email protected]; [email protected] Subject: [dpdk-dev] [PATCH] test/mempool: Fix illegal pointer access in mempool test
The value of parameter private_data_size of function rte_mempool_create() called in test_mempool() should not be 0, Otherwise, the function rte_pktmbuf_priv_size() called in rte_pktmbuf_init() will cause heap-buffer-overflow.
