David S. Miller b86d598d0c Merge branch 'vrf-cleanups-part-2'
Nikolay Aleksandrov says:

====================
vrf: cleanups part 2

This is the next part of vrf cleanups, patch 1 drops the SLAB_PANIC
when creating kmem cache since it's handled, patch 02 removes a slave
duplicate check which is already done by the lower/upper code, patch 3
moves the ndo_add_slave code around a bit so we can drop an error
label and patch 4 drops the master device checks which are unnecessary
because the ops are taken from the master device itself so it can't be
different.

Nikolay Aleksandrov 2640b39c28 vrf: ndo_add|del_slave drop unnecessary checks
When ndo_add|del_slave ops are used, they're taken from the respective
master device's netdev ops, so if the master device is a VRF only then
the VRF ops will get called thus no need to check the type of the
master.

Nikolay Aleksandrov 15df5e7112 vrf: move vrf_insert_slave so we can drop a goto label
We can simplify do_vrf_add_slave by moving vrf_insert_slave in the end
of the enslaving and thus eliminate an error goto label. It always
succeeds and isn't needed before that anyway.

Nikolay Aleksandrov e367da02fe vrf: don't panic on cache create failure
It's pointless to panic on cache create failure when that case is handled
and even more so since it's not a kernel-wide fatal problem so don't
panic.

Christophe Ricard 29e76924cf nfc: netlink: Add capability to reply to vendor_cmd with data
A proprietary vendor command may send back useful data to the user
application.

For example, the field level applied on the NFC router antenna.

Still based on net/wireless/nl80211.c implementation,
add nfc_vendor_cmd_alloc_reply_skb and nfc_vendor_cmd_reply in
order to send back over netlink data generated by a proprietary

David Vrabel 87ffd2b9bb x86/xen: make CONFIG_XEN depend on CONFIG_X86_LOCAL_APIC
Since commit feb44f1f7a (x86/xen:
Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need
a full APIC driver and thus should depend on X86_LOCAL_APIC.

This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by
disabling Xen support in this configuration.

Users needing Xen support in a non-SMP i386 kernel will need to enable
CONFIG_X86_UP_APIC.

It would seem vrf_master_ifindex_rcu() can be called without RCU held in
other contexts as well so introduce a new helper which acquires rcu and
returns the ifindex.
Also add curly braces around both the "if" and "else" parts as per the
style guide.

Ying Xue 824e7383e9 lwtunnel: Fix the sparse warnings in fib_encap_match
When CONFIG_LWTUNNEL config is not enabled, the lwtstate_free() is not
declared in lwtunnel.h at all. However, even in this case, the function
is still referenced in fib_semantics.c so that there appears the
following sparse warnings:

net/ipv4/fib_semantics.c:553:17: error: undefined identifier 'lwtstate_free'
  CC      net/ipv4/fib_semantics.o
  net/ipv4/fib_semantics.c: In function ‘fib_encap_match’:

  cc1: some warnings being treated as errors
  make[1]: *** [net/ipv4/fib_semantics.o] Error 1
  make: *** [net/ipv4/fib_semantics.o] Error 2

To eliminate the error, we define an empty function for lwtstate_free()
in lwtunnel.h when CONFIG_LWTUNNEL is disabled.

Takashi Iwai 9003ebb13f ALSA: usb-audio: Fix runtime PM unbalance
The fix for deadlock in PM in commit [1ee23fe07ee8: ALSA: usb-audio:
Fix deadlocks at resuming] introduced a new check of in_pm flag.
However, the brainless patch author evaluated it in a wrong way
(logical AND instead of logical OR), thus usb_autopm_get_interface()
is wrongly called at probing, leading to unbalance of runtime PM
refcount.

This patch fixes it by correcting the logic.

Roland Dreier 0f69a38737 target: Fix handling of small allocation lengths in REPORT LUNS
REPORT LUNS should not fail just because the allocation length is less
than 16.  The relevant section of SPC-4 is:

  4.2.5.6 Allocation length

  The ALLOCATION LENGTH field specifies the maximum number of bytes or
  blocks that an application client has allocated in the Data-In
  Buffer. The ALLOCATION LENGTH field specifies bytes unless a
  different requirement is stated in the command definition.

  An allocation length of zero specifies that no data shall be
  transferred. This condition shall not be considered an error.

So we should just truncate our response rather than return an error.

====================
Intel Wired LAN Driver Updates 2015-08-18

This series contains updates to igb, e100, e1000e and ixgbe.

Shota Suzuki provides a fix for a possible overflow in
igb_set_interrupt_capability() which leads to an oops.  When changing the
number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same
manner as when initializing the igb driver.

Vasily Averin provides a fix for a missing rtnl_unlock() for when we
error out due to not being able to allocate memory for our queues.

Stefan Assman provides a couple of fixes for igb/igbvf.  First changes
the igb driver in probe to simply call igb_enable_sriov() instead of
igb_sriov_reinit() since we are starting from scratch.  Then in igbvf,
fix the driver where it does not clear the buffer_info->dma in all
cases after calling dma_unmap_single(), which was found by changing the
MTU twice.

Richard Cochran implements the periodic output function using the
programmable clock outputs available in i210 when possible, falling
back to the target time for longer periods.

Todd adds support for the Marvell PHY 1512 which is required for i354
devices.  Then updates igb to make sure SR-IOV init uses the correct
number of queues, since recent changes could result in the PF holding
onto all of the queues.

Alex Williamson provides a fix in the case where a guest OS does not
support hot-unplug, so disable SR-IOV prior to unregister_netdev() to
avoid the problem.

Jia-Ju Bai provides several patches, first knocks some collecting dust
off an old e100 driver to add a check to avoid a null pointer
dereference.  Then cleans up a possible resource leak by releasing the
skb buffer allocated when the e100_xmit_prepare() runs into an issue
in the DMA mapping.  In igb, add a missing rtnl_unlock() for when we
error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme().
Provides a e1000e fix, based on suggestions from Alex Duyck to move
head/tail register writing to e1000_configure_tx/rx() to avoid a
possible null pointer dereference (similar to igb driver).  Lastly,
fix a possible memory leak in igb_probe(), where the memory shadow_vfta
allocated by kcalloc in igb_sw_init() is not freed.

Mark simplifies port-specific macros for ixgbe by eliminating explicit
comparisons with 0 and enclose formal parameters in parens to eliminate
the risk of an operator precedence issue.

Sven Eckelmann fd7dec25a1 batman-adv: Fix memory leak on tt add with invalid vlan
The object tt_local is allocated with kmalloc and not initialized when the
function batadv_tt_local_add checks for the vlan. But this function can
only cleanup the object when the (not yet initialized) reference counter of
the object is 1. This is unlikely and thus the object would leak when the
vlan could not be found.

Instead the uninitialized object tt_local has to be freed manually and the
pointer has to set to NULL to avoid calling the function which would try to
decrement the reference counter of the not existing object.

D in DSA patches

The D in DSA is distributed, meaning multiple switches can be
connected together. Currently no mainline system does this, and so the
code is broken. This patchset contains two fixes, and a small helper.

With three of more switches, the current device tree binding is not
sufficient to express the routing between the switches. The first
patch extends the binding, in a backwards compatible way, to allow a
link between a switch to describe all the switches accessible over the
link, not just the direct neighbor.

The third patch fixes the port configuration on newer devices for
links connecting switches.

With more than two switches in a hierarchy, it becomes necessary to
describe multi-hop routes between switches. The current binding does
not allow this, although the older platform_data did. Extend the link
property to be a list rather than a single phandle to a remote switch.
It is then possible to express that a port should be used to reach
more than one switch and the switch maybe more than one hop away.
