Re: [libvirt] [PATCHv2 12/12] qemu: fix infinite loop in OOM error path

A loop in qemuPrepareHostdevPCIDevices() intended to cycle through all the objects on the list pcidevs was doing "while (listcount > 0)", but nothing in the body of the loop was reducing the size of the list - it was instead removing items from a *different* list. It has now been safely changed to a for() loop. --- src/qemu/qemu_hostdev.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_hostdev.c b/src/qemu/qemu_hostdev.c index 09ac6ad..404939e 100644 --- a/src/qemu/qemu_hostdev.c +++ b/src/qemu/qemu_hostdev.c @@ -638,8 +638,8 @@ inactivedevs: /* Only steal all the devices from driver->activePciHostdevs. We will * free them in virObjectUnref(). */ - while (virPCIDeviceListCount(pcidevs) > 0) { - virPCIDevicePtr dev = virPCIDeviceListGet(pcidevs, 0); + for (i = 0; i < virPCIDeviceListCount(pcidevs); i++) { + virPCIDevicePtr dev = virPCIDeviceListGet(pcidevs, i); virPCIDeviceListSteal(driver->activePciHostdevs, dev); }
