Commit f462141f introduced clean up code when usb_qdev_init() fails. Unfortunately it calls .handle_destroy() when .init() was never invoked or failed. This can lead to crashes when .handle_destroy() tries to clean up things that were never initialized. This patch is careful to undo only those steps that completed along the usb_qdev_init() code path. It's not as pretty as the unified error handling in f462141f but it's necessary.

Use qdev_init() instead of qdev_init_nofail(), usb device initialization can fail, most common case being port and device speed mismatch. Handle failures correctly and pass up NULL pointers then. Also fixup usb_create_simple() callers (only one was buggy) to properly check for NULL pointers before referncing the usb_create_simple() return value.

This patch makes qemu assign a port when creating the device, not when attaching it. For most usb devices this isn't a noticable difference because they are in attached state all the time. The change affects usb-host devices which live in detached state while the real device is unplugged from the host. They have a fixed port assigned all the time now instead of getting grabbing one on attach and releasing it at detach, i.e. they stop floating around at the usb bus. The change also allows to simplify usb-hub. It doesn't need the handle_attach() callback any more to configure the downstream ports. This can be done at device initialitation time now. The changed initialization order (first grab upstream port, then register downstream ports) also fixes some icky corner cases. For example it is not possible any more to plug the hub into one of its own downstream ports. The usb host adapters must care too. USBPort->dev being non-NULL doesn't imply any more the device is in attached state. The host adapters must additionally check the USBPort->dev->attached flag.

Note this fixes 2 things in one go, first of all the device_destroy bus op should be a device_detach bus op, as pending async packets from the device should be cancelled on detach not on destroy. Secondly having this as a bus op won't work with companion controllers, since then there will be 1 bus driven by the ehci controller and thus 1 set of bus ops, but the device being detached may be downstream of a handed over port. Making the detach of a downstream device a port op allows the ehci controller to forward this to the companion controller port for handed over ports.

This patch adds USBBusOps struct with (for now) only a single callback which is called when a device is about to be destroyed.

Yes, seriously. There is no migration support at all for usb devices. They loose state, especially the device address, and stop responding because of that. Oops. Luckily there is so much broken usb hardware out there that the guest usually just kicks the device hard (via port reset and reinitialization), then continues without a hitch. So we got away with that in a surprising high number of cases. The arrival of remote wakeup (which enables autosuspend support) changes that picture though. The usb devices also forget that it they are supposed to wakeup, so they don't do that. The host also doesn't notice the device stopped working in case it suspended the device and thus expects it waking up instead of polling it. Result is that your mouse is dead. Lets start fixing that. Add a vmstate struct for USBDevice. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

This allows to explictily set the physical port where you want to plug the usb device. Example: -device usb-tablet,bus=usb.0,port=2 With explicit port addressing qemu can and will not automagically add USB Hubs. This means that: (a) You can plug two devices of your choice into the two uhci root ports. (b) If you want plug in more that two devices you have to care about adding a hub yourself. Plugging a hub works this way: -device usb-hub,bus=usb.0,port=1 Use this to add a device to the hub: -device usb-tablet,bus=usb.0,port=1.1 Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

error_report() terminates the message with a newline. Strip it it from its arguments. This fixes a few error messages lacking a newline: net_handle_fd_param()'s "No file descriptor named %s found", and tap_open()'s "vnet_hdr=1 requested, but no kernel support for IFF_VNET_HDR available" (all three versions). There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.
