2014-09-30virtio-net: fix virtio-net child refcount in transportsGonglei1-0/+1
object_initialize() leaves the object with a refcount of 1. object_property_add_child() adds its own reference which is dropped again when the property is deleted. The upshot of this is that we always have a refcount >= 1. Upon hot unplug the virtio-net child is not finalized! Drop our reference after the child property has been added to the parent.

virtio-net-pci, virtio-net-s390, and virtio-net-ccw all duplicate the qdev properties of their VirtIONet child. This approach does not work well with string or pointer properties since we must be careful about leaking or double-freeing them. Use the QOM alias property to forward property accesses to the VirtIONet child. This way no duplication is necessary.

2014-09-18virtio-pci: fix migration for pci bus masterMichael S. Tsirkin1-19/+20
Current support for bus master (clearing OK bit) together with the need to support guests which do not enable PCI bus mastering, leads to extra state in VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version migration for the case when guests use the device before setting DRIVER_OK. Rip out VIRTIO_PCI_FLAG_BUS_MASTER_BUG and implement a simpler work-around: treat clearing of PCI_COMMAND as a virtio reset. Old guests never touch this bit so they will work. As reset clears device status, DRIVER and MASTER bits are now in sync, so we can fix up cross-version migration simply by synchronising them, without need to detect a buggy guest explicitly. Drop tracking VIRTIO_PCI_FLAG_BUS_MASTER_BUG completely. As reset makes the device quiescent, in the future we'll be able to drop checking OK bit in a bunch of places.

2014-07-06virtio-pci: fix MSI memory region use after freePaolo Bonzini1-2/+2
After memory region QOMification QEMU is stricter in detecting wrong usage of the memory region API. Here it detected a memory_region_destroy done before the corresponding memory_region_del_subregion; the memory_region_destroy is done by msix_uninit_exclusive_bar, the memory_region_del_subregion is done by the PCI core's pci_unregister_io_regions before pc->exit is called. The problem was introduced by commit 06a1307379fcd6c551185ad87679cd7ed896b9ea virtio-pci: add device_unplugged callback As noted in that commit log, virtio device kick callbacks need to be stopped before generic virtio is cleaned up. This is because these are notifications from pci proxy to the generic virtio device so they need to be stopped in the unplug call before the virtio device is unrealized. However interrupts are notifications from the virtio device to the pci proxy so they need to stay around while the device is realized. The memory API misuse caused an assertion when hot-unplugging virtio devices. Using the API correctly fixes the assertion. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Michael S.

2014-07-01virtio-blk: replace x-iothread with iothread link propertyStefan Hajnoczi1-0/+2
Up until now -device virtio-blk-pci,x-iothread=<id> was used to assign an IOThread. This was a temporary solution while we cleaned up QOM link properties. This patch switches over to a QOM link property since it is now possible to restrict the setter to unrealized instances and automatically unref the IOThread when the virtio-blk-pci device is freed. Since the "iothread" property is a QOM property and not a qdev property, we must alias it explicitly for virtio-blk-pci, as well as CCW and s390-virtio.

2014-06-29virtio: add endian-ambivalent support to VirtIODeviceGreg Kurz1-4/+4
Some CPU families can dynamically change their endianness. This means we can have little endian ppc or big endian arm guests for example. This has an impact on legacy virtio data structures since they are target endian. We hence introduce a new property to track the endianness of each virtio device. It is reasonnably assumed that endianness won't change while the device is in use : we hence capture the device endianness when it gets reset. We migrate this property in a subsection, after the device descriptor. This means the load code must not rely on it until it is restored. As a consequence, the vring sanity checks had to be moved after the call to vmstate_load_state(). We enforce paranoia by poisoning the property at the begining of virtio_load().

Of course, this will have to change if we want to support target endianness changes at run-time. Let's move the TARGET_WORDS_BIGENDIAN bits out to a new helper and have virtio_is_big_endian() implemented on top of it. This patch doesn't change any functionality.

2014-03-19qom: Add check() argument to object_property_add_link()Stefan Hajnoczi1-0/+1
There are currently three types of object_property_add_link() callers: 1. The link property may be set at any time. 2. The link property of a DeviceState instance may only be set before realize. 3. The link property may never be set, it is read-only. Something similar can already be achieved with object_property_add_str()'s set() argument. Follow its example and add a check() argument to object_property_add_link(). Also provide default check() functions for case #1 and #2. Case #3 is covered by passing a NULL function pointer.

2014-03-19qom: Make QOM link property unref optionalStefan Hajnoczi1-1/+2
Some object_property_add_link() callers expect property deletion to unref the link property object. Other callers expect to manage the refcount themselves. The former are currently broken and therefore leak the link property object. This patch adds a flags argument to object_property_add_link() so the caller can specify which refcount behavior they require. The new OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be unreferenced when the property is deleted. This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c, s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c. Rationale for refcount behavior: * hw/core/qdev.c - bus children are explicitly unreferenced, don't interfere - parent_bus is essentially a read-only property that doesn't hold a refcount, don't unref - hotplug_handler is leaked, do unref * hw/dma/xilinx_axidma.c - rx stream "dma" links are set using set_link, therefore they need unref - tx streams are set using set_link, therefore they need unref * hw/net/xilinx_axienet.c - same reasoning as hw/dma/xilinx_axidma.c * hw/pcmcia/pxa2xx.c - pxa2xx bypasses set_link and therefore does not use refcounts * hw/s390x/s390-virtio-bus.c * hw/virtio/virtio-pci.c * hw/virtio/virtio-rng.c * ui/console.c - set_link is used and there is no explicit unref, do unref Cc: Peter Crosthwaite <peter.crosthwaite@petalogix.com> Cc: Alexander Graf <agraf@suse.de> Cc: Anthony Liguori <aliguori@amazon.com> Cc: "Michael S.

2013-12-09virtio-pci: add device_unplugged callbackPaolo Bonzini1-2/+10
This fixes a crash in hot-unplug of virtio-pci devices behind a PCIe switch. The crash happens because the ioeventfd is still set whent the child is destroyed (destruction happens in postorder). Then the proxy tries to unset to ioeventfd, but the virtqueue structure that holds the EventNotifier has been trashed in the meanwhile. kvm_set_ioeventfd_pio does not expect failure and aborts. The fix is simply to move parts of uninitialization to a new device_unplugged callback, which is called before the child is destroyed.
