net caif: Register properly as a pernet subsystem.

2012-01-28T02:06:03+00:00

caif is a subsystem and as such it needs to register with
register_pernet_subsys instead of register_pernet_device.

Among other problems using register_pernet_device was resulting in
net_generic being called before the caif_net structure was allocated.
Which has been causing net_generic to fail with either BUG_ON's or by
return NULL pointers.

A more ugly problem that could be caused is packets in flight why the
subsystem is shutting down.

To remove confusion also remove the cruft cause by inappropriately
trying to fix this bug.

With the aid of the previous patch I have tested this patch and
confirmed that using register_pernet_subsys makes the failure go away as
it should.

caif: Remove bad WARN_ON in caif_dev

2012-01-17T15:46:55+00:00

Remove WARN_ON and bad handling of SKB without destructor callback
in caif_flow_cb. SKB without destructor cannot be handled as an
error case.

  percpu: Remove irqsafe_cpu_xxx variants

Fix up conflict in arch/x86/include/asm/percpu.h due to clash with
cebef5beed3d ("x86: Fix and improve percpu_cmpxchg{8,16}b_double()")
which edited the (now removed) irqsafe_cpu_cmpxchg*_double code.

percpu: Remove irqsafe_cpu_xxx variants

2011-12-22T18:40:20+00:00

We simply say that regular this_cpu use must be safe regardless of
preemption and interrupt state.  That has no material change for x86
and s390 implementations of this_cpu operations.  However, arches that
do not provide their own implementation for this_cpu operations will
now get code generated that disables interrupts instead of preemption.

-tj: This is part of on-going percpu API cleanup.  For detailed
     discussion of the subject, please refer to the following thread.

   Please, this kind of stuff rots forever and not using bool properly
   drives me crazy.

Joe Perches  gave me the spatch script:

	@@
	bool b;
	@@
	-b = 0
	+b = false
	@@
	bool b;
	@@
	-b = 1
	+b = true

I merely installed coccinelle, read the documentation and took credit.

caif: Replace BUG_ON with WARN_ON.

2011-12-06T22:21:47+00:00

BUG_ON is too strict in a number of circumstances,
use WARN_ON instead. Protocol errors should not halt the system.

caif: Stash away hijacked skb destructor and call it later

2011-12-05T23:27:56+00:00

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.
