7d31130428 caif: Stash away hijacked skb destructor and call it later
This patch adds functionality for avoiding orphaning SKB too early.
The original skb is stashed away and the original destructor is called
from the hi-jacked flow-on callback. If CAIF interface goes down and a
hi-jacked SKB exists, the original skb->destructor is restored.

0e4c7d85d5 caif: Add support for flow-control on device's tx-queue
Flow control is implemented by inspecting the qdisc queue length
in order to detect potential overflow on the TX queue. When a threshold
is reached flow-off is sent upwards in the CAIF stack. At the same time
the skb->destructor is hi-jacked by orphaning the SKB and the original
destructor is replaced with a "flow-on" callback. When the "hi-jacked"
SKB is consumed the queue should be empty, and the "flow-on" callback
is called and xon is sent upwards in the CAIF stack.

7ad65bf68d caif: Add support for CAIF over CDC NCM USB interface
NCM 1.0 does not support anything but Ethernet framing, hence
CAIF payload will be put into Ethernet frames.

Discovery is based on fixed USB vendor 0x04cc (ST-Ericsson),
product-id 0x230f (NCM). In this variant only CAIF payload is sent over
the NCM interface.

The CAIF stack (cfusbl.c) will when USB interface register first check if
we got a CDC NCM USB interface with the right VID, PID.
It will then read the device's Ethernet address and create a 'template'
Ethernet TX header, using a broadcast address as the destination address,
and EthType 0x88b5 (802.1 Local Experimental - vendor specific).

A protocol handler for 0x88b5 is setup for reception of CAIF frames from
the CDC NCM USB interface.

08613e4626 caif: Fix BUG() with network namespaces
The caif code will register its own pernet_operations, and then register
a netdevice_notifier. Each time the netdevice_notifier is triggered,
it'll do some stuff... including a lookup of its own pernet stuff with
net_generic().

If the net_generic() call ever returns NULL, the caif code will BUG().
That doesn't seem *so* unreasonable, I suppose — it does seem like it
should never happen.

However, it *does* happen. When we clone a network namespace,
setup_net() runs through all the pernet_operations one at a time. It
gets to loopback before it gets to caif. And loopback_net_init()
registers a netdevice... while caif hasn't been initialised. So the caif
netdevice notifier triggers, and immediately goes BUG().

We could imagine a complex and overengineered solution to this generic
class of problems, but this patch takes the simple approach. It just
makes caif_device_notify() *not* go looking for its pernet data
structures if the device it's being notified about isn't a caif device
in the first place.

dec17b7451 Remove redundant linux/version.h includes from net/
It was suggested by "make versioncheck" that the follwing includes of
linux/version.h are redundant:

  /home/jj/src/linux-2.6/net/caif/caif_dev.c: 14 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/caif/chnl_net.c: 10 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/ipv4/gre.c: 19 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/netfilter/ipset/ip_set_core.c: 20 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/netfilter/xt_set.c: 16 linux/version.h not needed.

and it seems that it is right.

Beyond manually inspecting the source files I also did a few build
tests with various configs to confirm that including the header in
those files is indeed not needed.

Here's a patch to remove the pointless includes.

b2df5a8446 net/caif: Fix dangling list pointer in freed object on error.
rtnl_link_ops->setup(), and the "setup" callback passed to alloc_netdev*(),
cannot make state changes which need to be undone on failure.  There is
no cleanup mechanism available at this point.

So we have to add the caif private instance to the global list once we
are sure that register_netdev() has succedded in ->newlink().

Otherwise, if register_netdev() fails, the caller will invoke free_netdev()
and we will have a reference to freed up memory on the chnl_net_list.

01a859014b caif: checking the wrong variable
In the original code we check if (servl == NULL) twice.  The first time
should print the message that cfmuxl_remove_uplayer() failed and set
"ret" correctly, but instead it just returns success.  The second check
should be checking the value of "ret" instead of "servl".

a3106d032f Net: caif: Makefile: Remove deprecated items
Changed Makefile to use <modules>-y instead of <modules>-objs
because -objs is deprecated and not mentioned in
Documentation/kbuild/makefiles.txt.

Also, use the ccflags-$ flag instead of EXTRA_CFLAGS because EXTRA_CFLAGS is
deprecated and should now be switched.

Last but not least, took out if-conditionals.
