Re: [libvirt] [PATCH v2] tests: fix segfault in objecteventtest

Test 12 from objecteventtest (createXML add event) segaults on FreeBSD with bus error. At some point it calls testNodeDeviceDestroy() from the test driver. And it fails when it tries to unlock the device in the "out:" label of this function. Unlocking fails because the previous step was a call to virNodeDeviceObjRemove from conf/node_device_conf.c. This function removes the given device from the device list and cleans up the object, including destroying of its mutex. However, it does not nullify the pointer that was given to it. As a result, we end up in testNodeDeviceDestroy() here: out: if (obj) virNodeDeviceObjUnlock(obj); And instead of skipping this, we try to do Unlock and fail because of malformed mutex. Change virNodeDeviceObjRemove to use double pointer and set pointer to NULL. --- src/conf/node_device_conf.c | 13 +++++++------ src/conf/node_device_conf.h | 2 +- src/node_device/node_device_hal.c | 4 ++-- src/test/test_driver.c | 2 +- 4 files changed, 11 insertions(+), 10 deletions(-)
