Subject: [PATCH 4/4] xhci: Fix USB3 NULL pointer dereference at logical
disconnect.
Hub driver will try to disable a USB3 device twice at logical disconnect,
racing with xhci_free_dev() callback from the first port disable.
This can be triggered with "udisksctl power-off --block-device <disk>"
or by writing "1" to the "remove" sysfs file for a USB3 device
in 4.17-rc4.
USB3 devices don't have a similar disabled link state as USB2 devices,
and use a U3 suspended link state instead. In this state the port
is still enabled and connected.
hub_port_connect() first disconnects the device, then later it notices
that device is still enabled (due to U3 states) it will try to disable
the port again (set to U3).
The xhci_free_dev() called during device disable is async, so checking
for existing xhci->devs[i] when setting link state to U3 the second time
was successful, even if device was being freed.
The regression was caused by, and whole thing revealed by,
Commit 44a182b9d177 ("xhci: Fix use-after-free in xhci_free_virt_device")
which sets xhci->devs[i]->udev to NULL before xhci_virt_dev() returned.
and causes a NULL pointer dereference the second time we try to set U3.
Fix this by checking xhci->devs[i]->udev exists before setting link state.
The original patch went to stable so this fix needs to be applied there as
well.
