* | ehci: stop recursive calls to ehci_work_bhGerd Hoffmann2017-06-132-0/+8
| | | | | | | | | | | | | | | | | | | | | | Can happen with usb-storage devices: ehci_work_bh calls usb-storage, usb-storage calls into block layer, block layer may run BHs. Add a simple bool and just do nothing in case we figure ehci_work_bh is active. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20170612073109.25930-1-kraxel@redhat.com
* | xhci: only update dequeue ptr on completed transfersGerd Hoffmann2017-06-121-2/+4
|/ | | | | | | | | | | | | | The dequeue pointer should only be updated in case the transfer is actually completed. If we update it for inflight transfers we will not pick them up again after migration, which easily triggers with HID devices as they typically have a pending transfer, waiting for user input to happen.

* char: make chr_fe_deinit() optionaly delete backendMarc-André Lureau2017-06-022-7/+2Star
| | | | | | | | | | | This simplifies removing a backend for a frontend user (no need to retrieve the associated driver and separate delete call etc). NB: many frontends have questionable handling of ending a chardev. They should probably delete the backend to prevent broken reusage.

* char: move CharBackend handling in char-fe unitMarc-André Lureau2017-06-023-2/+3
| | | | | | | | | | | | | | Move all the frontend struct and methods to a seperate unit. This avoids accidentally mixing backend and frontend calls, and helps with readabilty. Make qemu_chr_replay() a macro shared by both char and char-fe. Export qemu_chr_write(), and use a macro for qemu_chr_write_all() (nb: yes, CharBackend is for char frontend :) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

* ehci: fix frame timer invocation.Gerd Hoffmann2017-05-291-3/+10
| | | | | | | | | | | | | ehci registers ehci_frame_timer as both timer and bottom half, which turned out to be a bad idea as it can be called as bottom half then while it is running as timer, and it isn't prepared to handle recursive calls. Change the timer func to just schedule the bottom half to avoid this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The spec says: Suspend: (PORT_SUSPEND) This field indicates whether or not the device on this port is suspended. Setting this field causes the device to suspend by not propagating bus traffic downstream. This field may be reset by a request or by resume signaling from the device attached to the port. I can't find any specific statement like "the PORT_SUSPEND field is reset automatically on remote wakeup", but without this patch, the only way to reset it is via the ClearPortFeature request so the ".. or by resume signaling from the device" clause is clearly not implemented on the remote wakeup path. The default xhci Windows driver does not issue the ClearPortFeature request and suspended devices attached to a hub don't properly get out of the suspended state. Interestingly, the default uhci Windows driver *does* issue the ClearPortFeature request and does not exhibit this problem.

Place a 'dc->vmsd' check prior to it so that we do not segfault for such devices. NOTE: This doesn't compromise the functioning of --only-migratable option as all the unmigratable devices do set their 'dc->vmsd'.

* xhci: properties cleanupGerd Hoffmann2017-02-231-3/+26
| | | | | | | | | | | | | | | Split xhci properties into common and nec specific. Move the backward compat flags to nec, so the new qemu-xhci devices doesn't carry on the compatibiity stuff. Move the msi/msix switches too and just enable msix for qemu-xhci. Also move the intrs and slots properties. Wasn't a great idea to make them configurable in the first place, nobody needs this.

| | | | | | | | | | | Curiously, unrealize() is not being used, but it seems more appropriate than handle_destroy() together with realize(). It is more ubiquitous destroy name in qemu code base and may throw errors.

| | | | | | | | | | | | | | Check message size too when figuring whenever we should expect more data. Fix debug message to show useful data, p->iov.size is fixed anyway if we land there, print how much we got meanwhile instead. Also check announced message size against actual message size. That is a more general fix for CVE-2017-5898 than commit "c7dfbf3 usb: ccid: check ccid apdu length".

* xhci: drop ER_FULL_HACK workaroundGerd Hoffmann2017-02-211-106/+11Star
| | | | | | | | | | | | | | | | | | | | The nec/renesas driver problems have finally been debugged and root caused, see commit "7da76e1 xhci: fix event queue IRQ handling". It's pretty clear now that (a) The whole "driver can't handle ring full" story is most likely wrong. (b) The ER_FULL_HACK workaround based on the false assumtion doesn't much. It avoids the driver crashing (without commit 7da76e1), but it doesn't make usb work. (c) With 7da76e1 applied it doesn't trigger any more. So, lets kill it. Or, to be exact, lets almost kill it. Some data fields are kept unused in the state struct, for live migration backward compatibility.
