From 8d3708efece06212bde6b1e10b2251931e1e9961 Mon Sep 17 00:00:00 2001 From: Herbert Guan Date: Mon, 10 Jul 2017 19:13:46 +0800 Subject: [PATCH] test/bonding: fix memory corruptions There were double-free problems in some test cases, which will cause a duplicated mbuf will be added into mempool. After double-free, some new allocated mbuf will hold a same address and thus cause the memory corruption. Another minor issue is that in some test cases, allocated mbuf will not be released after test case exits. Hopefully these leaked mbuf will be released by the next test case in its setup phase when stopping the virtual pmd ports, while this do is a memory leak of the exited test case. To fix above 2 issues, this patch will do: 1) Release virtual pmd ports' tx queue in the clean up function remove_slaves_and_stop_bonded_device() of each test cases. 2) Do not release allocated mbufs for test bursts. These mbufs will be released in remove_slaves_and_stop_bonded_device() when test case exits.
