commit 2ab13292d7a314fa45de0acc808e41aaad31989c upstream.

The BRIM Brothers Zone DPMX is a bicycle powermeter. This ID is for the USB
serial interface in its charging dock for the control pods, via which some
settings for the pods can be modified.

commit 2ce9d2272b98743b911196c49e7af5841381c206 upstream.

Some code (all error handling) submits CDBs that are allocated
on the stack.  This breaks with CB/CBI code that tries to create
URB directly from SCSI command buffer - which happens to be in
vmalloced memory with vmalloced kernel stacks.

Let's make copy of the command in usb_stor_CB_transport.

commit fd9afd3cbe404998d732be6cc798f749597c5114 upstream.

According to Dave Miller "the networking stack has a
hard requirement that all SKBs which are transmitted
must have their completion signalled in a fininte
amount of time. This is because, until the SKB is
freed by the driver, it holds onto socket,
netfilter, and other subsystem resources."

In summary, this means that using TX IRQ throttling
for the networking gadgets is, at least, complex and
we should avoid it for the time being.

<content type='text'>
commit 2fae9e5a7babada041e2e161699ade2447a01989 upstream.

This patch fixes a NULL pointer dereference caused by a race codition in
the probe function of the legousbtower driver. It re-structures the
probe function to only register the interface after successfully reading
the board's firmware ID.

The probe function does not deregister the usb interface after an error
receiving the devices firmware ID. The device file registered
(/dev/usb/legousbtower%d) may be read/written globally before the probe
function returns. When tower_delete is called in the probe function
(after an r/w has been initiated), core dev structures are deleted while
the file operation functions are still running. If the 0 address is
mappable on the machine, this vulnerability can be used to create a
Local Priviege Escalation exploit via a write-what-where condition by
remapping dev-&gt;interrupt_out_buffer in tower_write. A forged USB device
and local program execution would be required for LPE. The USB device
would have to delay the control message in tower_probe and accept
the control urb in tower_open whilst guest code initiated a write to the
device file as tower_delete is called from the error in tower_probe.

This bug has existed since 2003. Patch tested by emulated device.

<title>USB: change bInterval default to 10 ms</title>

commit 08c5cd37480f59ea39682f4585d92269be6b1424 upstream.

Some full-speed mceusb infrared transceivers contain invalid endpoint
descriptors for their interrupt endpoints, with bInterval set to 0.
In the past they have worked out okay with the mceusb driver, because
the driver sets the bInterval field in the descriptor to 1,
overwriting whatever value may have been there before.  However, this
approach was never sanctioned by the USB core, and in fact it does not
work with xHCI controllers, because they use the bInterval value that
was present when the configuration was installed.

Currently usbcore uses 32 ms as the default interval if the value in
the endpoint descriptor is invalid.  It turns out that these IR
transceivers don't work properly unless the interval is set to 10 ms
or below.  To work around this mceusb problem, this patch changes the
endpoint-descriptor parsing routine, making the default interval value
be 10 ms rather than 32 ms.

<title>USB: avoid left shift by -1</title>

commit 53e5f36fbd2453ad69a3369a1db62dc06c30a4aa upstream.

UBSAN complains about a left shift by -1 in proc_do_submiturb().  This
can occur when an URB is submitted for a bulk or control endpoint on
a high-speed device, since the code doesn't bother to check the
endpoint type; normally only interrupt or isochronous endpoints have
a nonzero bInterval value.

Aside from the fact that the operation is illegal, it shouldn't matter
because the result isn't used.  Still, in theory it could cause a
hardware exception or other problem, so we should work around it.
This patch avoids doing the left shift unless the shift amount is &gt;= 0.

The same piece of code has another problem.  When checking the device
speed (the exponential encoding for interrupt endpoints is used only
by high-speed or faster devices), we need to look for speed &gt;=
USB_SPEED_SUPER as well as speed == USB_SPEED HIGH.  The patch adds
this check.

Aside from the fact that the operation is illegal, it shouldn't matter
because the result isn't used.  Still, in theory it could cause a
hardware exception or other problem, so we should work around it.
This patch avoids doing the left shift unless the shift amount is &gt;= 0.

The same piece of code has another problem.  When checking the device
speed (the exponential encoding for interrupt endpoints is used only
by high-speed or faster devices), we need to look for speed &gt;=
USB_SPEED_SUPER as well as speed == USB_SPEED HIGH.  The patch adds
this check.
