commit c0f5ecee4e741667b2493c742b60b6218d40b3aa upstream.
The buffer for responses must not overflow.
If this would happen, set a flag, drop the data and return
an error after user space has read all remaining data.

[ no commit upstream, since usb_alloc_coherent usage was removed from
the driver before this was fixed ]
Commit cafbe85 ("USB: cdc-wdm: better allocate a buffer that is at least
as big as we tell the USB core") introduced a regression: it changed
the size used in usb_alloc_coherent, but failed to do the same for the
usb_free_coherent calls.
It also was marked for stable and got backported to older kernels. But
in the upstream kernel, the usage of usb_alloc_coherent was right after
removed from the driver, so upstream doesn't have this problem, while
the stable kernels still have, and thus need this fix.

commit e7d491a19d3e3aac544070293891a2542ae0c565 upstream.
This USB V.92/V.32bis Controllered Modem have the USB vendor ID 0x0572
and device ID 0x1340. It need the NO_UNION_NORMAL quirk to be recognized.

commit 99f347caa4568cb803862730b3b1f1942639523f upstream.
If a device specifies zero endpoints in its interface descriptor,
the kernel oopses in acm_probe(). Even though that's clearly an
invalid descriptor, we should test wether we have all endpoints.
This is especially bad as this oops can be triggered by just
plugging a USB device in.

The WDM_READ flag is normally cleared by wdm_int_callback
before resubmitting the read urb, and set by wdm_in_callback
when this urb returns with data or an error. But a crashing
device may cause both a read error and cancelling all urbs.
Make sure that the flag is cleared by wdm_read if the buffer
is empty.
We don't clear the flag on errors, as there may be pending
data in the buffer which should be processed. The flag will
instead be cleared on the next wdm_read call.

commit fec67b45bf045582c3172101970090d640cd56d9 upstream.
[v2: Editorial changes suggested by Sergei Shtylyov]
These modems use the Qualcomm MSM Interface (QMI) protocol for
management of their CDC ECM like wwan interface. This driver
is perfect for exporting the protocol to userspace.
The created character device will be indistinguishable from a
common AT command based Device Management interface, so
userspace applications must do some intelligent matching
on the USB device.

commit 6b0b79d38806481c1c8fffa7c5842f3c83679a42 upstream.
We cannot dereference a removed USB interface for
dev_printk. Use pr_debug instead where necessary.
Flush errors are expected if device is unplugged and are
therefore best ingored at this point.
Move the kill_urbs() call in wdm_release with dev_dbg()
for the non disconnect, as we know it has already been
called if WDM_DISCONNECTING is set. This does not
actually fix anything, but keeps the code more consistent.

commit 711c68b3c0f7a924ffbee4aa962d8f62b85188ff upstream.
We must not allow the input buffer length to change while we're
shuffling the buffer contents. We also mustn't clear the WDM_READ
flag after more data might have arrived. Therefore move both of these
into the spinlocked region at the bottom of wdm_read().
When reading desc->length without holding the iuspin lock, use
ACCESS_ONCE() to ensure the compiler doesn't re-read it with
inconsistent results.

commit 15699e6fafc3a90e5fdc2ef30555a04dee62286f upstream.
The probe does not strictly require the USB_CDC_DMM_TYPE
descriptor, which is a good thing as it makes the driver
usable on non-conforming interfaces. A user could e.g.
bind to it to a CDC ECM interface by using the new_id and
bind sysfs files. But this would fail with a 0 buffer length
due to the missing descriptor.
Fix by defining a reasonable fallback size: The minimum
device receive buffer size required by the CDC WMC standard,

[Not upstream as it was fixed differently for 3.3 with a much more
"intrusive" rework of the driver - gregkh]
There is a race condition involving acm_tty_hangup() and acm_tty_close()
where hangup() would attempt to access tty->driver_data without proper
locking and NULL checking after close() has potentially already set it
to NULL. One possibility to (sporadically) trigger this behavior is to
perform a suspend/resume cycle with a running WWAN data connection.
This patch addresses the issue by introducing a NULL check for
tty->driver_data in acm_tty_hangup() protected by open_mutex and exiting
gracefully when hangup() is invoked on a device that has already been
closed.

On some failures, the country_code field of an acm structure is freed
without freeing the acm structure itself. Elsewhere, operations including
memcpy and kfree are performed on the country_code field. The patch sets
the country_code field to NULL when it is freed, and likewise sets the
country_code_size field to 0.

There's a race between the USB disconnect handler and the TTY close
handler which may cause the acm object to be freed while it's still
being used. This may lead to things like
http://article.gmane.org/gmane.linux.usb.general/54250
and
https://lkml.org/lkml/2011/5/29/64
This is the simplest fix I could come up with. Holding on to open_mutex
while closing the TTY device prevents acm_disconnect() from freeing the
acm object between acm->port.count drops to 0 and the TTY side of the
cleanups are finalized.

This patch (as1482) adds a macro for testing whether or not a
pm_message value represents an autosuspend or autoresume (i.e., a
runtime PM) event. Encapsulating this notion seems preferable to
open-coding the test all over the place.

This adds the Nokia E7 and C7 to the list of devices in cdc-acm, allowing
the secondary ACM channel on the device to be exposed. Without this patch
the ACM driver won't claim this secondary channel as it's marked as
having a vendor-specific protocol.

The Droids MuIn LCD operates like a serial remote terminal.
Data received are displayed directly on the LCD. This patch
fixes the kernel null pointer oops when it is plugged in.
Add NO_DATA_INTERFACE quirk to tell the driver that "control"
and "data" interfaces are not separated for this device, which
prevents dereferencing a null pointer in the device probe code.
