[libvirt] [PATCH 1/5] domaincapstest: Don't leak cpu definitions

When generating domain capabilities, we need to fake host CPU to get reproducible result. We do this by copying a pre-existent CPU config and setting VIR_TEST_MOCK_FAKE_HOST_CPU env variable which is then consumed by qemucpumock. However, we forget to free the CPU copy afterwards. 2,196 (2,016 direct, 180 indirect) bytes in 18 blocks are definitely lost in loss record 291 of 297 at 0x4838B86: calloc (vg_replace_malloc.c:762) by 0x57CB6A0: g_malloc0 (in /usr/lib64/libglib-2.0.so.0.6000.7) by 0x4A0F72D: virCPUDefNew (cpu_conf.c:87) by 0x4A0FAC7: virCPUDefCopyWithoutModel (cpu_conf.c:235) by 0x4A0FBBE: virCPUDefCopy (cpu_conf.c:273) by 0x10E3C0: testUtilsHostCpusGetDefForArch (testutilshostcpus.h:157) by 0x10E3C0: fakeHostCPU (domaincapstest.c:61) by 0x10E3C0: fillQemuCaps (domaincapstest.c:86) by 0x10E3C0: test_virDomainCapsFormat (domaincapstest.c:234) by 0x10F4BC: virTestRun (testutils.c:146) by 0x10DE93: doTestQemuInternal (domaincapstest.c:301) by 0x10E13D: doTestQemu (domaincapstest.c:332) by 0x1124CF: testQemuCapsIterate (testutilsqemu.c:635) by 0x10DCE3: mymain (domaincapstest.c:435) by 0x10FD8B: virTestMain (testutils.c:916) Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- tests/domaincapstest.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tests/domaincapstest.c b/tests/domaincapstest.c index a4a443b1d6..9f5eab3230 100644 --- a/tests/domaincapstest.c +++ b/tests/domaincapstest.c @@ -56,7 +56,7 @@ fillStringValues(virDomainCapsStringValuesPtr values, ...) static int fakeHostCPU(virArch arch) { - virCPUDefPtr cpu; + g_autoptr(virCPUDef) cpu = NULL; if (!(cpu = testUtilsHostCpusGetDefForArch(arch))) { virReportError(VIR_ERR_INTERNAL_ERROR, -- 2.24.1
