2016-09-06 Thread Tim Gardner 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

This commit can fix this issue

commit ab2a4bf83902c170d29ba130a8abb5f9d90559e1
Author: Alan Stern 
Date:   Mon Jun 27 10:23:10 2016 -0400

USB: don't free bandwidth_mutex too early

The USB core contains a bug that can show up when a USB-3 host
controller is removed.  If the primary (USB-2) hcd structure is
released before the shared (USB-3) hcd, the core will try to do a
double-free of the common bandwidth_mutex.

The problem was described in graphical form by Chung-Geol Kim, who
first reported it:

=
 At *remove USB(3.0) Storage
 sequence <1> --> <5> ((Problem Case))
=
  VOLD

   |peer_hcd(kref=2)|
   |__|
|_
   |<2>   |
   |New USB BUS #2|
   |  |
   |peer_hcd(kref=1)  |
   |  |

 | |__|
 |
___  |
   |<3>| |
   |dwc3_otg_sm_work   | |
   |usb_put_hcd| |
   |primary_hcd(kref=1)| |
   |___| |
_|_  |
   |<4>| |
   |New USB BUS #1 | |
   |hcd_release| |
   |primary_hcd(kref=0)| |
   |   | |
   |bandXX_mutex(free) |<-
   |___|
   (( VOLD ))
__|___
   |<5>   |
   |  SCSI|
   |usb_put_hcd   |
   |peer_hcd(kref=0)  |
   |*hcd_release  |
   |bandXX_mutex(free*)|<- double free
   |__|

=

This happens because hcd_release() frees the bandwidth_mutex whenever
it sees a primary hcd being released (which is not a very good idea
in any case), but in the course of releasing the primary hcd, it
changes the pointers in the shared hcd in such a way that the shared
hcd will appear to be primary when it gets released.

This patch fixes the problem by changing hcd_release() so that it
deallocates the bandwidth_mutex only when the _last_ hcd structure
referencing it is released.  The patch also removes an unnecessary
test, so that when an hcd is released, both the shared_hcd and
primary_hcd pointers in the hcd's peer will be cleared.
