After 27726d8c21 a privateData is allocated in virDomainHostdevDefAlloc(). However, the counter part - freeing them in Free() is missing which leads to the following memory leak: ==6489== 24 bytes in 1 blocks are definitely lost in loss record 684 of 1,003 ==6489== at 0x4C2C070: calloc (vg_replace_malloc.c:623) ==6489== by 0x54B7C94: virAllocVar (viralloc.c:560) ==6489== by 0x5517BE6: virObjectNew (virobject.c:193) ==6489== by 0x1B400121: qemuDomainHostdevPrivateNew (qemu_domain.c:798) ==6489== by 0x5557B24: virDomainHostdevDefAlloc (domain_conf.c:2152) ==6489== by 0x5575578: virDomainHostdevDefParseXML (domain_conf.c:12709) ==6489== by 0x5582292: virDomainDefParseXML (domain_conf.c:16995) ==6489== by 0x5583C98: virDomainDefParseNode (domain_conf.c:17470) ==6489== by 0x5583B07: virDomainDefParse (domain_conf.c:17417) ==6489== by 0x5583B95: virDomainDefParseFile (domain_conf.c:17441) ==6489== by 0x55A3F24: virDomainObjListLoadConfig (virdomainobjlist.c:465) ==6489== by 0x55A43E6: virDomainObjListLoadAllConfigs (virdomainobjlist.c:596) Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- src/conf/domain_conf.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 9f7b906..7d2d726 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -2214,6 +2214,9 @@ void virDomainHostdevDefClear(virDomainHostdevDefPtr def) } break; } + + virObjectUnref(def->privateData); + def->privateData = NULL; } void virDomainTPMDefFree(virDomainTPMDefPtr def) -- 2.8.4
