84e77a8bc7 USB CDC NCM errata updates for cdc_ncm host driver
Specification links:
- CDC NCM errata link:
  http://www.usb.org/developers/devclass_docs/NCM10_012011.zip
- CDC and WMC errata link:
  http://www.usb.org/developers/devclass_docs/CDC1.2_WMC1.1_012011.zip

Changes:
- driver updated to match cdc.h header with errata changes
- added support for USB_CDC_SET_NTB_INPUT_SIZE control request with
  8 byte length
- fixes to comply with specification: send only control requests supported by
  device, set number of datagrams for IN direction, connection speed structure
  update, etc.
- packet loss fixed for tx direction; misleading flag renamed.
- adjusted hard_mtu value.

We will leak the storage allocated by request_firmware() if the size of
the firmware is greater than KAWETH_FIRMWARE_BUF_SIZE.
This removes the leak by calling release_firmware() before we return
-ENOSPC.

f742aa8acb USB CDC NCM: tx_fixup() race condition fix
- tx_fixup() can be called from either timer callback or from xmit()
  in usbnet, so spinlock is added to avoid concurrency-related problem.
- minor correction due to checkpatch warning for some line over 80
  chars after previous patch was applied.

9e56790ad3 USB CDC NCM: Don't deref NULL in cdc_ncm_rx_fixup() and don't use uninitialized variable.
skb_clone() dynamically allocates memory and may fail. If it does it
returns NULL. This means we'll dereference a NULL pointer in
drivers/net/usb/cdc_ncm.c::cdc_ncm_rx_fixup().
As far as I can tell, the proper way to deal with this is simply to goto
the error label.

Furthermore gcc complains that 'skb' may be used uninitialized:
  drivers/net/usb/cdc_ncm.c: In function ‘cdc_ncm_rx_fixup’:
  drivers/net/usb/cdc_ncm.c:922:18: warning: ‘skb’ may be used uninitialized in this function
and I believe it is right. On the line where we
  pr_debug("invalid frame detected (ignored)" ...
we are using the local variable 'skb' but nothing has ever been assigned
to that variable yet. I believe the correct fix for that is to use
'skb_in' instead.

23f333a2bf drivers/net: don't use flush_scheduled_work()
flush_scheduled_work() is on its way out.  This patch contains simple
conversions to replace flush_scheduled_work() usage with direct
cancels and flushes.

Directly cancel the used works on driver detach and flush them in
other cases.

The conversions are mostly straight forward and the only dangers are,

* Forgetting to cancel/flush one or more used works.

* Cancelling when a work should be flushed (ie. the work must be
  executed once scheduled whether the driver is detaching or not).

I've gone over the changes multiple times but it would be much
appreciated if you can review with the above points in mind.

f4e8ab7cc4 smsc95xx: generate random MAC address once, not every ifup
The smsc95xx driver currently generates a new random MAC address
every time the interface is brought up. This makes it impossible to
override using the standard `ifconfig hw ether` approach.

Past patches tried to make the MAC address a module parameter or
base it off the die ID, but it seems to me much simpler (and
hopefully less controversial) to stick with the current random
generation scheme, but allow the user to change the address.

This patch does exactly that - it moves the random address
generation from smsc95xx_reset() into smsc95xx_bind(), so that it is
done once on module load, not on every ifup. The user can then
override this using the standard mechanisms.

Applies against 2.6.35 and linux-2.6 head.

c9cedbba0f ipheth: remove incorrect devtype to WWAN
The 'wwan' devtype is meant for devices that require preconfiguration
and *every* time setup before the ethernet interface can be used, like
cellular modems which require a series of setup commands on serial ports
or other mechanisms before the ethernet interface will handle packets.

As ipheth only requires one-per-hotplug pairing setup with no
preconfiguration (like APN, phone #, etc) and the network interface is
usable at any time after that initial setup, remove the incorrect
devtype wwan.

cc28a20e77 introduce cx82310_eth: Conexant CX82310-based ADSL router USB ethernet driver
This patch introduces cx82310_eth driver - driver for USB ethernet port of
ADSL routers based on Conexant CX82310 chips. Such routers usually have
ethernet port(s) too which are bridged together with the USB ethernet port,
allowing the USB-connected machine to communicate to the network (and also
internet through the ADSL, of course).

This is my first driver, so please check thoroughly. As there's no protocol
documentation, it was done with usbsnoop dumps from Windows driver, some
parts (the commands) inspired by cxacru driver and also other usbnet drivers.
The driver passed my testing - some real work and also pings sized from 0 to
65507 B.

The only problem I found is the ifconfig error counter. When I return 0 (or 1
but empty skb) from rx_fixup(), usbnet increases the error counter although
it's not an error condition (because packets can cross URB boundaries). Maybe
the usbnet should be fixed to allow rx_fixup() to return empty skbs (or some
other value, e.g. 2)?

The USB ID of my device is 0x0572:0xcb01 which conflicts with some ADSL modems
using cxacru driver (they probably use the same chipset but simpler
firmware). The modems seem to use bDeviceClass 0 and iProduct "ADSL USB
MODEM", my router uses bDeviceClass 255 and iProduct "USB NET CARD". The
driver matches only devices with class 255 and checks for the iProduct string
during init. I already posted a patch for the cxacru driver to ignore these
devices.

the operation.  Since ETHTOOL_GDRVINFO no longer requires the driver
to implement any operations, do not require net_device::ethtool_ops to
be set either.

This patch makes rx_submit() return an error code, and makes some call sites
that care check the return value. This is important because it lets us properly
handle cases where the device isn't ready to handle URB submissions (e.g., when
it is autosuspended under some drivers); previously, we would attempt and fail
to submit URBs and reschedule ourselves to try and fail again. This patch is

e9162ab161 dm9601: fix phy/eeprom write routine
Use correct bit positions in DM_SHARED_CTRL register for writes.

Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which
came with a driver CD containing a Linux driver. This driver turns out to
be a copy of dm9601.c with symbols renamed and my copyright stripped.
That aside, it did contain 1 functional change in dm_write_shared_word(),
and after checking the datasheet the original value was indeed wrong
(read versus write bits).

On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s.
On other devices the difference is less spectacular, but still significant
(~30%).

In order for cdc_ether to handle these devices the GUID in the MDLM descriptor

CDC Ethernet MBM devices can be identified by the GUID.

This is the same solution used in Carl Nordbeck's mbm driver,
http://kerneltrap.org/mailarchive/linux-usb/2008/11/17/4141384/thread

eb4fd8cd35 net/usb: add sierra_net.c driver
Re-submitted based on comments from netdev community.
Summary of the changes:
1. Improved error handling.
2. Added the missing timeout arguments to usb_control_msg().

The following is a new Linux driver which exposes certain models of Sierra
Wireless modems to the operating system as Network Interface Cards (NICs).

This driver requires a version of the sierra.c driver which supports
blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
(i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
The version of sierra.c which supports blacklisting is
available from the sierra wireless knowledge base page for older kernels. It is
also available in Linux kernel starting from version 2.6.31.

This driver works with all Sierra Wireless devices configured with PID=68A3
like USB305, USB306 provided the corresponding firmware version is I2.0
(for USB305) or M3.0 (for USB306) and later.
This driver will not work with earlier firmware versions than the ones shown
above. In this case the driver will issue an error message indicating
incompatibility and will not serve the device's USB-to-WWAN interface.

Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
A series of hook functions are provided in sierra_net.c which are called by
usbnet.c in response to a particular condition such as receipt or transmission
of a data packet. As such, usbnet.c does most of the work of making
a modem appear to the system as a network device and for properly exchanging
traffic between the USB subsystem and the Network card interface.
Sierra_net.c is concerned with managing the data exchanged between the
USB-to-WWAN interface and the upper layers of the operating system.

Converts the list and the core manipulating with it to be the same as uc_list.

+uses two functions for adding/removing mc address (normal and "global"
 variant) instead of a function parameter.
+removes dev_mcast.c completely.
+exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
 manipulation with lists on a sandbox (used in bonding and 80211 drivers)

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

ace2a4d0fb MCS7830 USB-Ether: resume _with_ working link, via .reset_resume support
ChangeLog:
Implement .reset_resume support to retain a live network connection
during suspend despite USB power loss.
- rework operation to reference cached data in mcs7830_data and
  netdev->dev_addr
- update netdev->dev_addr only in case new MAC was set successfully
. Tests done:
  . ethtool -d pre-/post-suspend: register values match
  . running ssh session suspend, resume: works
  . ifdown device, suspend, resume: works
  . ifup, suspend, unplug, resume: WORKS (eth1 is removed, re-ifup of eth1
    after card replug works)
  . verified identical MAC in ifconfig post-resume
    (ok, should be verified on network side to be fully certain...)

Keywords: suspend resume network connection dead interface down
