Fixed by always initializing message buffer\nto NULL and calling free everytime rte_mp_request_sync\nis used.\n\nv5:\n- change prefixes in commit titles.\n\nv4:\n- fixed checkpatch issues\n\nv3:\n- rework of the patchset\n- caller is no longer responsible for freeing buffers on failure\n- caller still has to free response buffers on success\n- patchset reduced from 8 patches to 2\n\nv2:\n- resending as patchset to make it easier to review it.\n- changed commit message as requested.\n- added bugzilla id.\n\nBugzilla ID: 228\nHerakliusz Lipiec (2):\n  ipc: fix memory leak in sync request\n  net/tap: fix ipc related memory leak\n\n drivers/net/tap/rte_eth_tap.c           |  2 +-\n lib/librte_eal/common/eal_common_proc.c | 22 +++++++++++++++-------\n 2 files changed, 16 insertions(+), 8 deletions(-)"
