usb: hub: Clear Port Reset Change during init/resume

2013-11-29T19:11:52+00:00

commit e92aee330837e4911553761490a8fb843f2053a6 upstream.

This patch adds the Port Reset Change flag to the set of bits that are
preemptively cleared on init/resume of a hub. In theory this bit should
never be set unexpectedly... in practice it can still happen if BIOS,
SMM or ACPI code plays around with USB devices without cleaning up
correctly. This is especially dangerous for XHCI root hubs, which don't
generate any more Port Status Change Events until all change bits are
cleared, so this is a good precaution to have (similar to how it's
already done for the Warm Port Reset Change flag).

usb: fail on usb_hub_create_port_device() errors

2013-11-20T20:27:47+00:00

commit e58547eb9561a8a72d46e2d411090a614d33ac0e upstream.

Ignoring usb_hub_create_port_device() errors cause later NULL pointer
deference when uninitialized hub->ports[i] entries are dereferenced
after port memory allocation error.

usb: fix cleanup after failure in hub_configure()

2013-11-20T20:27:47+00:00

commit d0308d4b6b02597f39fc31a9bddf7bb3faad5622 upstream.

If the hub_configure() fails after setting the hdev->maxchild
the hub->ports might be NULL or point to uninitialized kzallocated
memory causing NULL pointer dereference in hub_quiesce() during cleanup.

Now after such error the hdev->maxchild is set to 0 to avoid cleanup
of uninitialized ports.
