5902385a24 tipc: obsolete the remote management feature
Due to the lacking of any credential, it's allowed to accept commands
requested from remote nodes to query the local node status, which is
prone to involve potential security risks. Instead, if we login to
a remote node with ssh command, this approach is not only more safe
than the remote management feature, but also it can give us more
permissions like changing the remote node configuration. So it's
reasonable for us to obsolete the remote management feature now.

76d7882420 tipc: remove unnecessary checking for node object
tipc_node_create routine doesn't need to check whether a node
object specified with a node address exists or not because its
caller(ie, tipc_disc_recv_msg routine) has checked this before
calling it.

fcb144b5df net/core: Use RCU_INIT_POINTER(x, NULL) in netpoll.c
This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL)

The rcu_assign_pointer() ensures that the initialization of a structure
is carried out before storing a pointer to that structure.
And in the case of the NULL pointer, there is no structure to initialize.
So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL)

fbd929f2dc bonding: support QinQ for bond arp interval
The bond send arp request to indicate that the slave is active, and if the bond dev
is a vlan dev, it will set the vlan tag in skb to notice the vlan group, but the
bond could only send a skb with 802.1q proto, not support for QinQ.

So add outer tag for lower vlan tag and inner tag for upper vlan tag to support QinQ,
The new skb will be consist of two vlan tag just like this:

dst mac | src mac | outer vlan tag | inner vlan tag | data | .....

If We don't need QinQ, the inner vlan tag could be set to 0 and use outer vlan tag
 as a normal vlan group.

Using "ip link" to configure the bond for QinQ and add test log:

ip link add link bond0  bond0.20 type vlan proto 802.1ad id 20
ip link add link bond0.20  bond0.20.200 type vlan proto 802.1q id 200

ifconfig bond0.20 11.11.20.36/24
ifconfig bond0.20.200 11.11.200.36/24

869b9b19b3 xen-netback: Stop using xenvif_tx_pending_slots_available
Since the early days TX stops if there isn't enough free pending slots to
consume a maximum sized (slot-wise) packet. Probably the reason for that is to
avoid the case when we don't have enough free pending slot in the ring to finish
the packet. But if we make sure that the pending ring has the same size as the
shared ring, that shouldn't really happen. The frontend can only post packets
which fit the to the free space of the shared ring. If it doesn't, the frontend
has to stop, as it can only increase the req_prod when the whole packet fits
onto the ring.
This patch avoid using this checking, makes sure the 2 ring has the same size,
and remove a checking from the callback. As now we don't stop the NAPI instance
on this condition, we don't have to wake it up if we free pending slots up.

the PF will comply, causing the VF to actually become promiscuous.
This will enable the VF to see all unicast traffic which might be intended for
other VMs, which we believe should not be possible.

This patch will cause the hypervisor to ignore the VF's request for changes in
its Rx mode (other than disabling it), preventing it from becoming promiscuous.

d836105100 bnx2x: Don't show port statistics for VFs
VFs are currently showing port statistics, although they can't really access
those - thus all such statistics will always show a value of 0.

This patch removes said statistics from the VF's view as to not confuse the
user.

2dc33bbc4f bnx2x: Remove the sriov VFOP mechanism
Since we now posses a workqueue dedicated for sriov, the paradigm that sriov-
related tasks cannot sleep is no longer correct.

The VFOP mechanism was the one previously supporting said paradigm - the sriov
related tasks were broken into segments which did not require sleep, and the
mechanism re-scheduled the next segment whenever possible.

This patch remvoes the VFOP mechanism altogether - the resulting code is a much
easier to follow code; The segments are gathered into straight-forward
functions which sleep whenever neccessary.

370d4a2659 bnx2x: Create workqueue for IOV related tasks
The bnx2x sriov mechanisms were done in the bnx2x slowpath workitem which
runs on the bnx2x's workqueue; This workitem is also responsible for the bottom
half of interrupt handling in the driver, and specifically it also receives
FW notifications of ramrod completions, allowing other flows to progress.

The original design of the sriov reltaed-flows was based on the notion such
flows must not sleep, since their context is the slowpath workitem.
Otherwise, we might reach timeouts - those flows may wait for ramrod completion
that will never arrive as the workitem wlll not be re-scheduled until that same
flow will be over.

In more recent time bnx2x started supporting features in which the VF interface
can be configured by the tools accessing the PF on the hypervisor.
This support created possible races on the VF-PF lock (which is taken either
when the PF is handling a VF message or when the PF is doing some slowpath work
on behalf of the VF) which may cause timeouts on the VF side and lags on the PF
side.

This patch changes the scheme - it creates a new workqueue for sriov related
tasks and moves all handling currently done in the slowpath task into the the
new workqueue.

e471b40321 mlx4: Use actual number of PCI functions (PF + VFs) for alias GUID logic
The code which is dealing with SRIOV alias GUIDs in the mlx4 IB driver has some
logic which operated according to the maximal possible active functions (PF + VFs).

After the single port VFs code integration this resulted in a flow of false-positive
warnings going to the kernel log after the PF driver started the alias GUID work.

Fix it by referring to the actual number of functions.

0fc3196603 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:

====================
Please pull this batch of wireless updates intended for 3.15!

For the mac80211 bits, Johannes says:

"This has a whole bunch of bugfixes for things that went into -next
previously as well as some other bugfixes I didn't want to rush into
3.14 at this point. The rest of it is some cleanups and a few small
features, the biggest of which is probably Janusz's regulatory DFS CAC
time code."

For the Bluetooth bits, Gustavo says:

"One more pull request to 3.15. This is mostly and bug fix pull request, it
contains several fixes and clean up all over the tree, plus some small new
features."

For the NFC bits, Samuel says:

"This is the NFC pull request for 3.15. With this one we have:

- Support for ISO 15693 a.k.a. NFC vicinity a.k.a. Type 5 tags. ISO
  15693 are long range (1 - 2 meters) vicinity tags/cards. The kernel
  now supports those through the NFC netlink and digital APIs.

- Support for TI's trf7970a chipset. This chipset relies on the NFC
  digital layer and the driver currently supports type 2, 4A and 5 tags.

- Support for NXP's pn544 secure firmare download. The pn544 C3 chipsets
  relies on a different firmware download protocal than the C2 one. We
  now support both and use the right one depending on the version we
  detect at runtime.

- Support for 4A tags from the NFC digital layer.

- A bunch of cleanups and minor fixes from Axel Lin and Thierry Escande."

For the iwlwifi bits, Emmanuel says:

"We were sending a host command while the mutex wasn't held. This
led to hard-to-catch races."

And...

"I have a fix for a "merge damage" which is not really a merge
damage: it enables scheduled scan which has been disabled in
wireless.git. Since you merged wireless.git into wireless-next.git,
this can now be fixed in wireless-next.git.

Besides this, Alex made a workaround for a hardware bug. This fix
allows us to consume less power in S3. Arik and Eliad continue to
work on D0i3 which is a run-time power saving feature. Eliad also
contributes a few bits to the rate scaling logic to which Eyal adds his
own contribution. Avri dives deep in the power code - newer firmware
will allow to enable power save in newer scenarios. Johannes made a few
clean-ups. I have the regular amount of BT Coex boring stuff. I disable
uAPSD since we identified firmware bugs that cause packet loss. One
thing that do stand out is the udev event that we now send when the
FW asserts. I hope it will allow us to debug the FW more easily."

Also included is one last iwlwifi pull for a build breakage fix...

For the Atheros bits, Kalle says:

"Michal now did some optimisations and was able to improve throughput by
100 Mbps on our MIPS based AP135 platform. Chun-Yeow added some
workarounds to be able to better use ad-hoc mode. Ben improved log
messages and added support for MSDU chaining. And, as usual, also some
smaller fixes."

Beyond that...

Andrea Merello continues his rtl8180 refactoring, in preparation for
a long-awaited rtl8187 driver.  We get a new driver (rsi) for the
RS9113 chip, from Fariya Fatima.  And, of course, we get the usual
round of updates for ath9k, brcmfmac, mwifiex, wil6210, etc. as well.
