Pull tile update from Chris Metcalf:
"The interesting bug fix is support for the upcoming "4.2" release of
the Tilera hypervisor, which by default launches Linux at privilege
level 2 instead of 1. The fix lets new and old hypervisors and
Linuxes interoperate more smoothly, so I've tagged it for
stable@kernel.org so that older Linuxes will be able to boot under the
newer hypervisor."* 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:

The driver and firmware sync up through SYNC messages, and the
firmware's affirmative reply to these SYNC messages appears to be the
"Reset" indication received via the status interrupt endpoint. Thus the
driver needs the status interrupt endpoint always active so that the
Reset indication can be received even if the netdev is closed, which is
the case right after device insertion.If the Reset indication is not received by the driver, it continues
sending SYNC messages to the firmware, which crashes about 10 seconds
later and the device stops responding.Signed-off-by: Dan Williams
Signed-off-by: David S. Miller -
Some drivers (sierra_net) need the status interrupt URB
active even when the device is closed, because they receive
custom indications from firmware. Add functions to refcount
the status interrupt URB submit/kill operation so that
sub-drivers and the generic driver don't fight over whether
the status interrupt URB is active or not.A sub-driver can call usbnet_status_start() at any time, but
the URB is only submitted the first time the function is
called. Likewise, when the sub-driver is done with the URB,
it calls usbnet_status_stop() but the URB is only killed when
all users have stopped it. The URB is still killed and
re-submitted for suspend/resume, as before, with the same
refcount it had at suspend.Signed-off-by: Dan Williams

be_close() followed by be_clear() is called as a part of cleanup in the

While cleaning RX queues, the CQ DB may be rung several times (with rearm)
while waiting for the flush compl. Each CQ-notify with rearm can result in
an event. The EQ may get full resulting in a HW error.Fix this by not re-arming the CQ while notifying a valid completion.
Also, there's no need to wait for 1ms after destroying RXQ, as the code in
be_rx_cq_clean() waits for the flush compl to arrive.Signed-off-by: Sathya Perla

Some ancient pHyp versions used to create a 8 bytes local-mac-address
property in the device-tree instead of a 6 bytes one for veth.The Linux driver code to deal with that is an insane hack which also
happens to break with some choices of MAC addresses in qemu by testing
for a bit in the address rather than just looking at the size of the
property.Sanitize this by doing the latter instead.

single_release() instead of seq_release() in the file_operations

Since commit 636f9d371f70f22961fd598fe18380057518ca31 ("cxgb4: Add
support for T4 configuration file"), t4_fw_hello may return a positive

After recent 86a9bad3 (net: vlan: add protocol argument to packet
tagging functions) my sky2 started to crash on receive of tagged
frames, with backtrace similar to#CRASH!!!
vlan_do_receive
__netif_receive_skb_core
__netif_receive_skb
netif_receive_skb
sky2_poll
...
__net_rx_action
__do_softirqThe problem turned out to be:
1) sky2 copies small packets from ring on RX, and in its
receive_copy() skb header is copied manually field, by field, and
only for some fields;2) 86a9bad3 added skb->vlan_proto, which vlan_untag() or
__vlan_hwaccel_put_tag() set, and which is later used in
vlan_do_receive().That patch updated copy_skb_header() for newly introduced
skb->vlan_proto, but overlooked the need to also copy it in sky2's
receive_copy().Because of 2, we have the following scenario:
- frame is received and tagged in a ring, by sky2_rx_tag(). Both
skb->vlan_proto and skb->vlan_tci are set;- later skb is decided to be copied, but skb->vlan_proto is
forgotten and becomes 0.- in the beginning of vlan_do_receive() we call
__be16 vlan_proto = skb->vlan_proto;
vlan_dev = vlan_find_dev(skb->dev, vlan_proto, vlan_id);which eventually invokes
vlan_proto_idx(vlan_proto)
and that routine BUGs for everything except ETH_P_8021Q and
ETH_P_8021AD.Oops.
Fix it.
P.S.
Stephen, I wonder, why copy_skb_header() is not used in
sky2.c::receive_copy() ? Problems, where receive_copy was updated field
by field showed several times already, e.g.3f42941b (sky2: propogate rx hash when packet is copied)

...It is easily reproducable by setting an MTU of 512 e. g. and sending
something likeping -s 1472 -c 1 -M do $SELF
from another box.
And this is because the rx->ax_skb is freed on error, but rx->ax_skb
is not reset, and the size is not reset to zero in this case.And since the skb is added again to the usbnet->done skb queue it is
accessing already freed memory, resulting in the BUG when freeing a
2nd time. I therefore think the value 0x0000004000000001 show in the

Pull i2c changes from Wolfram Sang:
- an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.- the core lost the detach_adapter() call. It has no users anymore and
was in the way for other cleanups. attach_adapter() is sadly still
there since there are users waiting to be converted.- the core gained a bus recovery infrastructure. I2C defines a way to
recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.- bigger driver cleanups for designware, s3c2410

In CPSW NAPI, after processing all interrupts IRQ is enabled and then book
keeping irq_enabled is updated. In random cases when a packet is transmitted
or received between processing packets and IRQ enabled, then just after
enabled IRQ and before irq_enabled is updated, ISR is called so IRQs are
not disabled as irq_enabled is still false and CPU gets locked in CPSW ISR.By changing the sequence as update the irq_enabled and then enable IRQ
fixes the issue. This issue is not captured always as it is a timing issue
whether Tx or Rx IRQ is invoked between packet processing and enable IRQ.Cc: Sebastian Siewior

#define XEN_NETBK_LEGACY_SLOTS_MAX XEN_NETIF_NR_SLOTS_MINThe fatal_skb_slots is the threshold to determine whether a packet is
malicious.XEN_NETBK_LEGACY_SLOTS_MAX is the maximum slots a valid packet can have at
this point. It is defined to be XEN_NETIF_NR_SLOTS_MIN because that's
guaranteed to be supported by all backends.Suggested-by: Ian Campbell

When RQ creation fails in be_open(), driver jumps to be_close() where
napi_disable() is done without a prior napi_enable(); leading to a hang.
This change is needed as there is no way to see if napi is enable/disabled.Signed-off-by: Kalesh AP
