2015-05-08usb: fix usb-net segfaultMichal Kazior
The dev->config pointer isn't set until guest system initializes usb devices (via usb_desc_set_config). However qemu networking can go through some motions prior to that, e.g.: #0 is_rndis (s=0x555557261970) at hw/usb/dev-network.c:653 #1 0x000055555585f723 in usbnet_can_receive (nc=0x55555641e820) at hw/usb/dev-network.c:1315 #2 0x000055555587635e in qemu_can_send_packet (sender=0x5555572660a0) at net/net.c:470 #3 0x0000555555878e34 in net_hub_port_can_receive (nc=0x5555562d7800) at net/hub.c:101 #4 0x000055555587635e in qemu_can_send_packet (sender=0x5555562d7980) at net/net.c:470 #5 0x000055555587dbca in tap_can_send (opaque=0x5555562d7980) at net/tap.c:172 The command to reproduce most reliably was: qemu-system-i386 -usb -device usb-net,vlan=0 -net tap,vlan=0 This wasn't strictly a problem with tap. Other networking endpoints (vde, user) could trigger this problem as well.

2015-05-08s390x/kvm: use ioctl KVM_S390_IRQ for vcpu interruptsJens Freimann
KVM_S390_INT uses only two parameter fields. This is not enough to pass all required information for certain interrupts. A new ioctl KVM_S390_IRQ is available which allows us to inject all local interrupts as defined in the Principles of Operation. It takes a struct kvm_s390_irq as a parameter which can store interrupt payload data for all interrupts. Let's use the new ioctl for injecting vcpu interrupts.

2015-05-08virtio-ccw: implement ->device_pluggedCornelia Huck
Let's move operations that are only valid after the backend has been realized to a ->device_plugged callback, just as virtio-pci does. Also reorder setting up the host feature bits to the sequence used by virtio-pci. While we're at it, also add a ->device_unplugged callback to stop ioeventfd, just to be on the safe side.

2015-05-08virtio-ccw: change realization sequenceCornelia Huck
virtio-ccw has an odd sequence of realizing devices: first the device-specific relization (net, block, ...), then the generic realization. It feels less odd to have the generic realization callback trigger the device-specific realization instead (and this also matches what virtio-pci does). One thing to note: We need to defer initializing the cu model in the sense id data until after the device-specific realization has been performed, as we need to refer to the virtio device's device_id.

2015-05-08s390-virtio: clear {used,avail}_event_idx on reset as wellChristian Borntraeger
The old s390-virtio transport clears the vring used/avail indices in the shared area on reset. When we enabled event_idx for virtio-blk, we noticed that this is not enough: We also need to clear the published used/avail event indices, or reboot will fail.

2015-05-08s390-virtio: use common featuresCornelia Huck
We used to avoid enabling event_idx for virtio-blk devices via s390-virtio, but we now have a workaround in place for guests trying to use the device before setting DRIVER_OK. Therefore, let's add DEFINE_VIRTIO_COMMON_FEATURES to the base device so all devices get those common features - and make s390-virtio use the same mechanism as the other transports do.

2015-05-08s390-virtio: Accommodate guests using virtqueues too earlyChristian Borntraeger
Feature updates are not a synchronuous operation for the legacy s390-virtio transport. This transport syncs the guest feature bits (those from finalize) on the set_status hypercall. Before that qemu thinks that features are zero, which means QEMU will misbehave, e.g. it will not write the event index, even if the guest asks for it. Let's detect the case where a kick happens before the driver is ready and force sync the features. With this workaround, it is now safe to switch to the common feature bit handling code as used by all other transports.
