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
device firmware does not handle fragmented messages
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
driver from CodeAurora use 4 kB. This is therefore
chosen as the new arbitrary default until the real
limit is known.
This should allow any QMI message to be transmitted
without fragmentation, fixing known issues with GPS
assistance data upload.

Suspending an open usbnet device results in constant
rescheduling of usbnet_bh.
commit 65841fd5 "usbnet: handle remote wakeup asap"
refactored the usbnet_bh code to allow sharing the
urb allocate and submit code with usbnet_resume. In
this process, a test for, and immediate return on,
ENOLINK from rx_submit was unintentionally dropped.
The rx queue will not grow if rx_submit fails,
making usbnet_bh reschedule itself. This results
in a softirq storm if the error is persistent.
rx_submit translates the usb_submit_urb error
EHOSTUNREACH into ENOLINK, so this is an expected
and persistent error for a suspended device. The
old code tested for this condition and avoided
rescheduling. Putting this test back.

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.

Currently we have no way to assign tty->port while performing tty
installation. There are two ways to provide the link tty_struct =>
tty_port. Either by calling tty_port_install from tty->ops->install or
tty_port_register_device called instead of tty_register_device when
the device is being set up after connected.
In this patch we modify most of the drivers to do the latter. When the
drivers use tty_register_device and we have tty_port already, we
switch to tty_port_register_device. So we have the tty_struct =>
tty_port link for free for those.

We allocate memory for 'req' with usb_alloc_urb() and then test
'if (!req || rx_submit(pnd, req, GFP_KERNEL | __GFP_COLD))'.
If we enter that branch due to '!req' then there is no problem. But if
we enter the branch due to 'req' being != 0 and the 'rx_submit()' call
being false, then we'll leak the memory we allocated.
Deal with the leak by always calling 'usb_free_urb(req)' when entering
the branch. If 'req' happens to be 0 then the call is harmless, if it
is not 0 then we free the memory we allocated but don't need.

The skb->pfmemalloc flag gets set to true iff during the slab allocation
of data in __alloc_skb that the the PFMEMALLOC reserves were used. If
page splitting is used, it is possible that pages will be allocated from
the PFMEMALLOC reserve without propagating this information to the skb.
This patch propagates page->pfmemalloc from pages allocated for fragments
to the skb.
It works by reintroducing and expanding the skb_alloc_page() API to take
an skb. If the page was allocated from pfmemalloc reserves, it is
automatically copied. If the driver allocates the page before the skb, it
should call skb_propagate_pfmemalloc() after the skb is allocated to
ensure the flag is copied properly.
Failure to do so is not critical. The resulting driver may perform slower
if it is used for swap-over-NBD or swap-over-NFS but it should not result
in failure.

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.

I noticed excess calls to skb_copy_expand() or memmove() in asix driver.
This driver needs to push 4 bytes in front of frame (packet_len)
and maybe add 4 bytes after the end (if padlen is 4)
So it should set needed_headroom & needed_tailroom to avoid
copies. But its not enough, because many packets are cloned
before entering asix_tx_fixup() and this driver use skb_cloned()
as a lazy way to check if it can push and put additional bytes in frame.
Avoid skb_copy_expand() expensive call, using following rules :
- We are allowed to push 4 bytes in headroom if skb_header_cloned()
is false (and if we have 4 bytes of headroom)
- We are allowed to put 4 bytes at tail if skb_cloned()
is false (and if we have 4 bytes of tailroom)
TCP packets for example are cloned, but skb_header_release()
was called in tcp stack, allowing us to use headroom for our needs.

If usbnet is resumed by remote wakeup, generally there are
some packets comming to be handled, so allocate and submit
rx URBs in usbnet_resume to avoid delays introduced by tasklet.
Otherwise, usbnet may have been runtime suspended before the
usbnet_bh is executed to schedule Rx URBs.
Without the patch, usbnet can't recieve any packets from peer
in runtime suspend state if runtime PM is enabled and
autosuspend_delay is set as zero.

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:
[ 15.562552] qmi_wwan 4-1.6:1.0: cdc-wdm0: USB WDM device

[ 15.570372] qcserial 4-1.6:1.3: Qualcomm USB modem converter detected
[ 15.570430] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB1
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.

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.

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid
recursive locking in usbnet_stop()) fixes the recursive locking
problem by releasing the skb queue lock before unlink, but may
cause skb traversing races:
- after URB is unlinked and the queue lock is released,
the refered skb and skb->next may be moved to done queue,
even be released
- in skb_queue_walk_safe, the next skb is still obtained
by next pointer of the last skb
- so maybe trigger oops or other problems
This patch extends the usage of entry->state to describe 'start_unlink'
state, so always holding the queue(rx/tx) lock to change the state if
the referd skb is in rx or tx queue because we need to know if the
refered urb has been started unlinking in unlink_urbs.
The other part of this patch is based on Huajun's patch:
always traverse from head of the tx/rx queue to get skb which is
to be unlinked but not been started unlinking.

Some RNDIS devices include a bogus CDC Union descriptor pointing
to non-existing interfaces. The RNDIS code is already prepared
to handle devices without a CDC Union descriptor by hardwiring
the driver to use interfaces 0 and 1, which is correct for the
devices with the bogus descriptor as well. So we can reuse the
existing workaround.

The asix.c USB Ethernet driver avoids ending a tx transfer with a zero-
length packet by appending a four-byte padding to transfers whose length
is a multiple of maxpacket. However, the hard-coded 512 byte maxpacket
length is valid for high-speed USB only; full-speed USB uses 64 byte
packets.

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.

problem by releasing the skb queue lock, but it makes usb_unlink_urb
racing with defer_bh, and the URB to being unlinked may be freed before

triggerd inside usb_unlink_urb.
The patch fixes the use-after-free problem by increasing URB
reference count with skb queue lock held before calling
usb_unlink_urb, so the URB won't be freed until return from

i.e usbnet_resume() is called in-between, tx data flow is stopped.

asix_rx_fixup() is complex, and does some unnecessary memory copies (at
least on x86 where NET_IP_ALIGN is 0)
Also, it tends to provide skbs with a big truesize (4096+256 with
MTU=1500) to upper stack, so incoming trafic consume a lot of memory and
I noticed early packet drops because we hit socket rcvbuf too fast.
Switch to a different strategy, using copybreak so that we provide nice
skbs to upper stack (including the NET_SKB_PAD to avoid future head
reallocations in some paths)
With this patch, I no longer see packets drops or tcp collapses on
various tcp workload with a AX88772 adapter.

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

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.

On MCORE2-machines commit ea812ca1b0
introduces a change which sets NET_IP_ALIGN to 0 by default. Which
triggered the bug on these machines.
This fix introduces a new RXW_PADDING define and uses this instead of
NET_IP_ALIGN. The name was taken from the original SMSC7500 driver which

MII Kconfig option is apart of the core networking drivers and
by default NET_CORE is enabled so drivers selecting MII will
have MII enabled as well. It was found using the randconfig
option during testing, MII would be selected but NET_CORE
could be disabled. This caused a dependency error.
Resolved the dependency by selecting NET_CORE when MII is
selected.
