This device provides QMI and ethernet functionality via a standard CDC
ethernet descriptor. But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface. Thus blacklist the device in cdc_ether and add its IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.

This patch removes a generic hard_header_len check from the usbnet
module that is causing dropped packages under certain circumstances
for devices that send rx packets that cross urb boundaries.
One example is the AX88772B which occasionally send rx packets that
cross urb boundaries where the remaining partial packet is sent with
no hardware header. When the buffer with a partial packet is of less
number of octets than the value of hard_header_len the buffer is
discarded by the usbnet module.
With AX88772B this can be reproduced by using ping with a packet
size between 1965-1976.
The bug has been reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=29082
This patch introduces the following changes:
- Removes the generic hard_header_len check in the rx_complete
function in the usbnet module.
- Introduces a ETH_HLEN check for skbs that are not cloned from
within a rx_fixup callback.
- For safety a hard_header_len check is added to each rx_fixup
callback function that could be affected by this change.
These extra checks could possibly be removed by someone
who has the hardware to test.
- Removes a call to dev_kfree_skb_any() and instead utilizes the
dev->done list to queue skbs for cleanup.
The changes place full responsibility on the rx_fixup callback
functions that clone skbs to only pass valid skbs to the
usbnet_skb_return function.

Another QMI speaking Qualcomm based device, which should be
driven by qmi_wwan, while cdc_ether should ignore it.
Like on other Huawei devices, the wwan function can appear
either as a single vendor specific interface or as a CDC ECM
class function using separate control and data interfaces.
The ECM control interface protocol is 0xff, likely in an
attempt to indicate that vendor specific management is
required.
In addition to the near standard CDC class, Huawei also add
vendor specific AT management commands to their firmwares.
This is probably an attempt to support non-Windows systems
using standard class drivers. Unfortunately, this part of
the firmware is often buggy. Linux is much better off using
whatever native vendor specific management protocol the
device offers, and Windows uses, whenever possible. This
means QMI in the case of Qualcomm based devices.
The E1820 has been verified to work fine with QMI.
Matching on interface number is necessary to distiguish the
wwan function from serial functions in the single interface
mode, as both function types will have class/subclass/function
set to ff/ff/ff.
The control interface number does not change in CDC ECM mode,
so the interface number matching rule is sufficient to handle
both modes. The cdc_ether blacklist entry is only relevant in
CDC ECM mode, but using a similar interface number based rule
helps document this as a transfer from one driver to another.
Other Huawei 02/06/ff devices are left with the cdc_ether driver
because we do not know whether they are based on Qualcomm chips.
The Huawei specific AT command management is known to be somewhat
hardware independent, and their usage of these class codes may
also be independent of the modem hardware.

The bogus address is always the same, and matches the address
suggested by many devices as a default address. It is likely a
hardcoded firmware default.
The circumstances where this bug has been observed indicates that
the trigger is related to timing or some other factor the host
cannot control. Repeating the exact same configuration sequence
that caused it to trigger once, will not necessarily cause it to
trigger the next time. Reproducing the bug is therefore difficult.
This opens up a possibility that the bug is more common than we can
confirm, because affected devices often will work properly again
after a reset. A procedure most users are likely to try out before
reporting a bug.
Unconditionally rewriting the destination address if the first digit
of the received packet is 0, is considered an acceptable compromise
since we already have to inspect this digit. The simplification will
cause unnecessary rewrites if the real address starts with 0, but this
is still better than adding additional tests for this particular case.

A number of LTE devices from different vendors all suffer from the
same firmware bug: Most of the packets received from the device while
it is attached to a LTE network will not have an ethernet header. The
devices work as expected when attached to 2G or 3G networks, sending
an ethernet header with all packets.
This driver is not aware of which network the modem attached to, and
even if it were there are still some packet types which are always
received with the header intact.
All devices supported by this driver have severely limited
networking capabilities:
- can only transmit IPv4, IPv6 and possibly ARP
- can only support a single host hardware address at any time
- will only do point-to-point communcation with the host
Because of this, we are able to reliably identify any bogus raw IP
packets by simply looking at the 4 IP version bits. All we need to
do is to avoid 4 or 6 in the first digit of the mac address. This
workaround ensures this, and fix up the received packets as necessary.
Given the distribution of the bug, it is believed that the source is
the chipset vendor. The devices which are verified to be affected are:
Huawei E392u-12 (Qualcomm MDM9200)
Pantech UML290 (Qualcomm MDM9600)
Novatel USB551L (Qualcomm MDM9600)
Novatel E362 (Qualcomm MDM9600)
It is believed that the bug depend on firmware revision, which means
that possibly all devices based on the above mentioned chipset may be
affected if we consider all available firmware revisions.
The information about affected devices and versions is likely
incomplete. As the additional overhead for packets not needing this
fixup is very small, it is considered acceptable to apply the
workaround to all devices handled by this driver.

commit bd877e4 ("net: qmi_wwan: use a single bind function for
all device types") made Gobi 1K devices fail probing.
Using the number of endpoints in the default altsetting to decide
whether the function use one or two interfaces is wrong. Other
altsettings may provide more endpoints.
With Gobi 1K devices, USB interface #3's altsetting is 0 by default, but
altsetting 0 only provides one interrupt endpoint and is not sufficent
for QMI. Altsetting 1 provides all 3 endpoints required for qmi_wwan
and works with QMI. Gobi 1K layout for intf#3 is:
Interface Descriptor: 255/255/255
bInterfaceNumber 3
bAlternateSetting 0
Endpoint Descriptor: Interrupt IN
Interface Descriptor: 255/255/255
bInterfaceNumber 3
bAlternateSetting 1
Endpoint Descriptor: Interrupt IN
Endpoint Descriptor: Bulk IN
Endpoint Descriptor: Bulk OUT
Prior to commit bd877e4, we would call usbnet_get_endpoints
before giving up finding enough endpoints. Removing the early
endpoint number test and the strict functional descriptor
requirement allow qmi_wwan_bind to continue until
usbnet_get_endpoints has made the final attempt to collect
endpoints. This restores the behaviour from before commit
bd877e4 without losing the added benefit of using a single bind
function.
The driver has always required a CDC Union functional descriptor
for two-interface functions. Using the existence of this
descriptor to detect two-interface functions is the logically
correct method.

These devices provide QMI and ethernet functionality via a standard CDC
ethernet descriptor. But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface. Thus blacklist the devices in cdc_ether and add their IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.

This fixes a hang on suspend due to calling wdm_suspend on
the unregistered data interface. The hang should have been
a NULL pointer reference had it not been for a logic error
in the cdc_wdm code.
commit 230718bd net: qmi_wwan: bind to both control and data interface
changed qmi_wwan to use cdc_wdm as a subdriver for devices with
a two-interface QMI/wwan function. The commit failed to update
qmi_wwan_suspend and qmi_wwan_resume, which were written to handle
either a single combined interface function, or no subdriver at all.
The result was that we called into the subdriver both when the
control interface was suspended and when the data interface was
suspended. Calling the subdriver suspend function with an
unregistered interface is not supported and will make the
subdriver bug out.

QMI requests exceeding 1500 bytes are possible and

very well. It is therefore necessary to increase
the maximum message size from the current 512 bytes.
The protocol message size limit is not documented
in any publicly known source, but the out of tree

chosen as the new arbitrary default until the real

Add 6 new devices and one modified device, based on
information from laptop vendor Windows drivers.
Sony provides a driver with two new devices using
a Gobi 2k+ layout (1199:68a5 and 1199:68a9). The
Sony driver also adds a non-standard QMI/net
interface to the already supported 1199:9011
Gobi device. We do not know whether this is an
alternate interface number or an additional
interface which might be present, but that doesn't
really matter.
Lenovo provides a driver supporting 4 new devices:
- MC7770 (1199:901b) with standard Gobi 2k+ layout
- MC7700 (0f3d:68a2) with layout similar to MC7710
- MC7750 (114f:68a2) with layout similar to MC7710
- EM7700 (1199:901c) with layout similar to MC7710
Note regaring the three devices similar to MC7710:
The Windows drivers only support interface #8 on these
devices. The MC7710 can support QMI/net functions on
interface #19 and #20 as well, and this driver is
verified to work on interface #19 (a firmware bug is
suspected to prevent #20 from working).
We do not enable these additional interfaces until they
either show up in a Windows driver or are verified to
work in some other way. Therefore limiting the new
devices to interface #8 for now.

Instead of class/subclass/protocol the vendor use fixed
interface numbers for each function, and the Windows
drivers use these numbers to match driver and function.
The driver has had its own interface number whitelisting
code to simulate this functionality. Replace this with
generic interface number matching now that the USB subsystem
support is there. This
- removes the need for a driver_info structure per
interface number,
- avoids running the probe function for unsupported
interfaces, and
- simplifies the code.

The usbnet API use the device ID table to store a pointer to
a minidriver. Setting a generic pointer for dynamic device
IDs will in most cases make them work as expected. usbnet
will otherwise treat the dynamic IDs as blacklisted. That is
rarely useful.
There is no standard class describing devices supported by
this driver, and most vendors don't even provide enough
information to allow vendor specific wildcard matching. The
result is that most of the supported devices must be
explicitly listed in the device table. Allowing dynamic IDs
to work both simplifies testing and verification of new
devices, and provides a way for end users to use a device
before the ID is added to the driver.

Ignoring interfaces with additional descriptors is not a reliable
method for locating the correct interface on Gobi devices. There
is at least one device where this method fails:
https://bbs.archlinux.org/viewtopic.php?id=143506
The result is that the AT command port (interface #2) is hidden
from qcserial, preventing traditional serial modem usage:

Use static interface numbers taken from the interface map in
qcserial for all Gobi devices instead:
Gobi 1K USB layout:
0: serial port (doesn't respond)
1: serial port (doesn't respond)
2: AT-capable modem port
3: QMI/net
Gobi 2K+ USB layout:
0: QMI/net
1: DM/DIAG (use libqcdm from ModemManager for communication)
2: AT-capable modem port
3: NMEA
This should be more reliable over all, and will also prevent the
noisy "probe failed" messages. The whitelisting logic is expected
to be replaced by direct interface number matching in 3.6.

Always bind to control interface regardless of whether
it is a shared interface or not.
A QMI/wwan function is required to provide both a control
interface (QMI) and a data interface (wwan). All devices
supported by this driver do so. But the vendors may
choose to use different USB descriptor layouts, and some
vendors even allow the same device to present different
layouts.
Most of these devices use a USB descriptor layout with a
single USB interface for both control and data. But some
split control and data into two interfaces, bound together
by a CDC Union descriptor on the control interface. Before
the cdc-wdm subdriver support was added, this split was
used to let cdc-wdm drive the QMI control interface and
qmi_wwan drive the wwna data interface.
This split driver model has a number of issues:
- qmi_wwan must match on the data interface descriptor,
which often are indistiguishable from data interfaces
belonging to other CDC (like) functions like ACM
- supporting a single QMI/wwan function requires adding
the device to two drivers
- syncronizing the probes among a number of drivers, to
ensure selecting the correct driver, is difficult unless
all drivers match on the same interface
This patch resolves these problems by using the same
probing mechanism as cdc-ether for devices with a two-
interface USB descriptor layout. This makes the driver
behave consistently, supporting both the control and data
part of the QMI/wwan function, regardless of the USB
descriptors.

It's touches a lot of different parts of the kernel, all USB drivers,

some changes that are needed for USB 3.0 power management updates.
There are also lots of new drivers, pimarily gadget, but others as well.
We deleted a staging driver, which was nice, and finally dropped the
obsolete usbfs code, which will make Al happy to never have to touch

There were some build errors in the tree that linux-next found a few

Merge tag 'usb-3.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB 3.5-rc1 changes from Greg Kroah-Hartman:
"Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.
It's touches a lot of different parts of the kernel, all USB drivers,
due to some API cleanups (getting rid of the ancient err() macro) and
some changes that are needed for USB 3.0 power management updates.
There are also lots of new drivers, pimarily gadget, but others as
well. We deleted a staging driver, which was nice, and finally
dropped the obsolete usbfs code, which will make Al happy to never
have to touch that again.
There were some build errors in the tree that linux-next found a few
days ago, but those were fixed by the most recent changes (all were
due to us not building with CONFIG_PM disabled.)

Add the ZTE (Vodafone) K3765-Z to the whitelist. This requires the
previous patch to make the whitelist with forced interface 4 generic
or the device fails to initialise. After applying this patch and
loading the Option driver without usb-modeswitch's bind all
interfaces trick, a wwan0 net interface and /dev/cdc-wdm0 device
file were created. Using Bjorn Mork's perl connection script a
connection was made to a mobile network using QMI and the network
interface's IPv4 address was configured OK.

Change the forced interface 4 whitelist to use the generic shared
binder instead of the Gobi specific one. Certain ZTE devices
(K3520-Z & K3765-Z) don't work with the Gobi version, but function
quite happily with the generic. This has been tested with the following
devices:
K3520-Z
K3565-Z
K3765-Z
K4505-Z
It hasn't been tested with the ZTE MF820D, which is the only other
device that uses this whitelist at present. Although Bjorn doesn't
expect any problems, any testing with that device would be appreciated.

Hub-initiated LPM is not good for USB communications devices. Comms
devices should be able to tell when their link can go into a lower power
state, because they know when an incoming transmission is finished.
Ideally, these devices would slam their links into a lower power state,
using the device-initiated LPM, after finishing the last packet of their
data transfer.
If we enable the idle timeouts for the parent hubs to enable
hub-initiated LPM, we will get a lot of useless LPM packets on the bus
as the devices reject LPM transitions when they're in the middle of
receiving data. Worse, some devices might blindly accept the
hub-initiated LPM and power down their radios while they're in the
middle of receiving a transmission.
The Intel Windows folks are disabling hub-initiated LPM for all USB
communications devices under a xHCI USB 3.0 host. In order to keep
the Linux behavior as close as possible to Windows, we need to do the
same in Linux.
Set the disable_hub_initiated_lpm flag for for all USB communications
drivers. I know there aren't currently any USB 3.0 devices that
implement these class specifications, but we should be ready if they do.

The MC77xx devices can operate in two modes: "Direct IP" or "QMI",
switchable using a password protected AT command. Both product ID
and USB interface configuration will change when switched.
The "sierra_net" driver supports the "Direct IP" mode. This driver
supports the "QMI" mode.
There are also multiple possible USB interface configurations in each
mode, some providing more than one wwan interface. Like many other
devices made for Windows, different interface types are identified
using a static interface number. We define a Sierra specific
interface whitelist to support this.

ZTE have yet to discover the magic of USB descriptors. These
devices use ff/ff/ff for class/subclass/protocol regardless of
function, except for usb-storage. Use an interface number
whitelist to force the driver to bind only to the QMI/wwan
interface.

Adding the Pantech UML290 and all non-QDL Gobi device IDs from the
qcserial driver now that we have support for shared net/QMI USB
interfaces. Most of these are not yet tested with this driver, but
should be mostly identical to tested devices, except for device IDs.
Gobi devices provide several different interfaces (serial/net/other)
using the exact same class, subclass and protocol values. This driver
will only support the net/QMI function while there are other drivers
supporting other device functions. The net/QMI interface number may
also differ from device to device. It has been noted that all the
other interfaces have additional functional descriptors, so we use that
to detect the interface supported by this driver.

Use the new cdc-wdm subdriver interface to create a device management
device even for USB devices having a single combined QMI/wwan USB
interface with three endpoints (int, bulk in, bulk out) instead of
separate data and control interfaces.
Some Huawei devices can be switched to a single interface mode for
use with other operating systems than Linux. This adds support
for these devices when they run in such non-Linux modes.

Some WWAN LTE/3G devices based on chipsets from Qualcomm provide
near standard CDC ECM interfaces in addition to the usual serial
interfaces. The Huawei E392/E398 are examples of such devices.
These typically cannot be fully configured using AT commands
over a serial interface. It is necessary to speak the proprietary
Qualcomm MSM Interface (QMI) protocol to the device to enable the
ethernet proxy functionality.
The devices embed the QMI protocol in CDC on the control interface,
using standard CDC commands and notifications. The do not otherwise
use CDC commands for the ethernet function. This driver does
therefore not need access to any other aspects of the control
interface than the descriptors attached to it.
Another driver, cdc-wdm, will provide userspace access to the
QMI protocol independently of this driver. To facilitate this,
this driver avoids binding to the control interface, and uses
only the associated data interface after parsing the common CDC
functional descriptors on the control interface.
You will want both the cdc-wdm and option drivers as companions to
this driver, to have full access to all interfaces and protocols
exported by the device.
