====================
This is a sizeable batch of updates intended for 3.6...

The bulk of the changes here are Bluetooth.  Gustavo says:

	Here goes the first Bluetooth pull request for 3.6, we have
	queued quite a lot of work. Andrei Emeltchenko added the AMP
	Manager code, a lot of work is needed, but the first bit are
	already there. This code is disabled by default.  Mat Martineau
	changed the whole L2CAP ERTM state machine code, replacing
	the old one with a new implementation. Besides that we had
	lot of coding style fixes (to follow net rules), more l2cap
	core separation from socket and many clean ups and fixed all
	over the tree.

Along with the above, there is a healthy dose of ath9k, iwlwifi,
and other driver updates.  There is also another pull from the
wireless tree to resolve some merge issues.  I also fixed-up some
merge discrepencies between net-next and wireless-next.

Currently the CNIC-related L2 CIDs (for sending control FCoE / iSCSI packets)
were at fixed position, according to the maximal number of RSS queues multiplied
by the number of traffic-classes. This change makes the CIDs dynamic, as they
are defined to be right after the highest RSS CID. This decreases the memory
allocated for the context.

In the current scheme the transmission queues of traffic-class 0 were 0-15, the
transmission queues of traffic-class 1 were 16-31 and so on. If the number of
RSS queues was smaller than 16, there were gaps in transmission queues
numbering, as well as in CIDs numbering. This is both a waste (especially when
16 is increased to 64), and may causes problems with flushing queues when
reducing the number of RSS queues (using ethtool -L). The new scheme eliminates
the gaps.

Pablo says:

====================
The following patchset provides fixes for issues that were recently introduced
by my new cthelper infrastructure. They have been spotted by Randy Dunlap,
Andrew Morton and Dan Carpenter.

The patches provide:

* compilation fixes if CONFIG_NF_CONNTRACK is disabled: I moved all the
  conntrack code from nfnetlink_queue.c to nfnetlink_queue_ct.c to avoid
  peppering the entire code with lots of ifdefs. I needed to rename
  nfnetlink_queue.c to nfnetlink_queue_core.c to get it working with the
  Makefile tweaks I've added.

* fix NULL pointer dereference via ctnetlink while trying to change the helper
  for an existing conntrack entry. I don't find any reasonable use case for
  changing the helper from one to another in run-time. Thus, now ctnetlink
  returns -EOPNOTSUPP for this operation.

* fix possible out-of-bound zeroing of the conntrack extension area due to
  the helper automatic assignation routine.

Included changes:

* major skb->data pointer usage fix
* interval version update
* added get_ethtool_stats() support
* endianess clean up
* routing protocol API improvement wrt TT commit code
* fix locking in hash table code
* minor cleanups and fixes

In "9cb01766 netfilter: add glue code to integrate nfnetlink_queue and ctnetlink"
the compilation with NF_CONNTRACK disabled is broken. This patch fixes this
issue.

I have moved the conntrack part into nfnetlink_queue_ct.c to avoid
peppering the entire nfnetlink_queue.c code with ifdefs.

I also needed to rename nfnetlink_queue.c to nfnetlink_queue_pkt.c
to update the net/netfilter/Makefile to support conditional compilation
of the conntrack integration.

This patch also adds CONFIG_NETFILTER_QUEUE_CT in case you want to explicitly
disable the integration between nf_conntrack and nfnetlink_queue.

This patch fixes the compilation of net/netfilter/nfnetlink_cthelper.c
if CONFIG_NF_CONNTRACK is not set.

This patch also moves the definition of the cthelper infrastructure to
the scope of NF_CONNTRACK things.

I have also renamed NETFILTER_NETLINK_CTHELPER by NF_CT_NETLINK_HELPER,
to use similar names to other nf_conntrack_netlink extensions. Better now
that this has been only for two days in David's tree.

Two new dependencies have been added:

* NF_CT_NETLINK
* NETFILTER_NETLINK_QUEUE

Since these infrastructure requires both ctnetlink and nfqueue.

This patch modifies __nf_ct_try_assign_helper in a way that invalidates support
for the following scenario:

1) attach the helper A for first time when the conntrack is created
2) attach new (different) helper B due to changes the reply tuple caused by NAT

eg. port redirection from TCP/21 to TCP/5060 with both FTP and SIP helpers
loaded, which seems to be a quite unorthodox scenario.

I can provide a more elaborated patch to support this scenario but explicit
helper attachment provides a better solution for this since now the use can
attach the helpers consistently, without relying on the automatic helper
lookup magic.

This patch fixes a possible out of bound zeroing of the conntrack helper
extension if the helper B uses more memory for its private data than
helper A.

The patch 1afc5679: "netfilter: nf_ct_helper: implement variable
length helper private data" from Jun 7, 2012, leads to the following
Smatch complaint:

net/netfilter/nf_conntrack_netlink.c:1231 ctnetlink_change_helper()
         error: we previously assumed 'help->helper' could be null (see line 1228)

This NULL dereference can be triggered with the following sequence:

1) attach the helper for first time when the conntrack is created.
2) remove the helper module or detach the helper from the conntrack
   via ctnetlink.
3) attach helper again (the same or different one, no matter) to the
   that existing conntrack again via ctnetlink.

This patch fixes the problem by removing the use case that allows you
to re-assign again a helper for one conntrack entry via ctnetlink since
I cannot find any practical use for it.

To ensure an entry isn't added twice all comparisons have to be protected by the
hash line write spinlock. This doesn't really hurt as the case that it is tried
to add an element already present to the hash shouldn't occur very often, so in
most cases the lock would have have to be taken anyways.

The primary entry and the corresponding secondary entries are missing when there
are no neighbors on the primary interface. This also causes the TT entries to

Added additional counters in a bat_stats structure, which are exported
through the ethtool api. The counters are specific to batman-adv and
includes:
 forwarded packets and bytes
 management packets and bytes (aggregated OGMs at this point)
 translation table packets

New counters are added by extending "enum bat_counters" in types.h and
adding corresponding  descriptive string(s) to bat_counters_strings in
soft-iface.c.

Counters are increased by calling batadv_add_counter() and incremented
by one by calling batadv_inc_counter().

The hash for claim and backbone hash in the bridge loop avoidance code receive

skb_linearize(skb) possibly rearranges the skb internal data and then changes
the skb->data pointer value. For this reason any other pointer in the code that
was assigned skb->data before invoking skb_linearise(skb) must be re-assigned.

In the current tt_query message handling code this is not done and therefore, in
case of skb linearization, the pointer used to handle the packet header ends up
in pointing to poisoned memory. The packet is then dropped but the
translation-table mechanism is corrupted.
