[libvirt] [PATCH] snapshot: fix double free issue for qemuImgBinary value in qemu_driver

*src/qemu/qemu_driver.c: in qemuDomainSnapshotForEachQcow() it will free up the memory of qemu_driver->qemuImgBinary in the cleanup tag which leads to the garbage value of qemuImgBinary and libvirtd crash when running "virsh snapshot-create" command next time. --- src/qemu/qemu_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index b94d1c4..bbe113f 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1735,7 +1735,7 @@ qemuDomainSnapshotForEachQcow2(struct qemud_driver *driver, ret = skipped ? 1 : 0; cleanup: - VIR_FREE(qemuimgarg[0]); + qemuimgarg[0] = NULL; return ret; } -- 1.7.1
