2b9253d2a0 iwlagn: fix dual-mode RXON
The PAN context has three states: disabled, disassociated
 and associated. It seems that wasn't quite as much of an
 issue in previous versions of the microcode, but now we
 really have to use all the three states properly. So add
 code to switch accordingly.

Additionally, PAN parameters need to be sent differently
and the timing for PAN RXON needs to be inbetween.

84288044dc ath9k: better position PAPRD debug message
the training power calculation indirectly depends on target power under
some scenarios, unless we have a valid training power, the PAPRD frames
won't be sent out. so when we get an invalid training power, its better
to display them before returning back.

fce041beb0 ath9k: unify edma and non-edma tx code, improve tx fifo handling
EDMA based chips (AR9380+) have 8 Tx FIFO slots, which are used to fix the
tx queue start/stop race conditions which have to be worked around for
earlier chips by keeping the last descriptor in the queue. The current code
stores all frames that do not fit onto the 8 FIFO slots in a separate
list. Whenever a FIFO slot is freed up, the next frame (or A-MPDU) from the
pending queue gets moved to that slot.

This process is not only inefficient, but also unnecessary. The code can
be improved visibly by keeping the pending queue fully linked, and moving
the contents of the entire queue to a FIFO slot as it becomes available.

This patch makes the necessary changes for that and also merges some code
that was duplicated for EDMA vs non-EDMA. It changes txq->axq_link to point
to the last descriptor instead of the link pointer, so that
ath9k_hw_set_desc_link can be used, which works on all chips.

With this patch, a small performance increase for non-aggregated traffic
was observed on AR9380 based embedded hardware.

7882513bac mac80211_hwsim driver support userspace frame tx/rx
This patch adds to mac80211_hwsim the capability to send traffic via
userspace.

Frame exchange between kernel and user spaces is done through generic
netlink communication protocol. A new generic netlink family
MAC80211_HWSIM is proposed, this family contains three basic commands
HWSIM_CMD_REGISTER, which is the command used to register a new
traffic listener, HWSIM_CMD_FRAME, to exchange the frames from kernel
to user and vice-versa, and HWSIM_CMD_TX_INFO_FRAME which returns
from user all the information about retransmissions, rates, rx signal,
and so on.

How it works:

Once the driver is loaded the MAC80211_HWSIM family will be registered.
In the absence of userspace daemon, the driver itselfs implements a
perfect wireless medium as it did in the past. When a daemon sends a
HWSIM_CMD_REGISTER command, the module stores the application PID, and
from this moment all frames will be sent to the registered daemon.

The user space application will be in charge of process/forward all
frames broadcast by any mac80211_hwsim radio. If the user application
is stopped, the kernel module will detect the release of the socket
and it will switch back to in-kernel perfect channel simulation.

The userspace daemon must be waiting for incoming HWSIM_CMD_FRAME
commands sent from kernel, for each HWSIM_CMD_FRAME command the
application will try to broadcast this frame to all mac80211_hwsim
radios, however the application may decide to forward/drop this frame.
In the case of forwarding the frame, a new HWSIM_CMD_FRAME command will

will be sent back to the kernel.

Also after the frame broadcast phase, a HWSIM_CMD_TX_INFO_FRAME
command will be sent from userspace to kernel, this command contains
all the information regarding the transmission, such as number of
tries, rates, ack signal, etc.

59342f6a6b zd1211rw: fix to work on OHCI
zd1211 devices register 'EP 4 OUT' endpoint as Interrupt type on USB 2.0:

      Endpoint Descriptor:
        bLength                 7
        bDescriptorType         5
        bEndpointAddress     0x04  EP 4 OUT
        bmAttributes            3
          Transfer Type            Interrupt
          Synch Type               None
          Usage Type               Data
        wMaxPacketSize     0x0040  1x 64 bytes
        bInterval               1

However on USB 1.1 endpoint becomes Bulk:

      Endpoint Descriptor:
        bLength                 7
        bDescriptorType         5
        bEndpointAddress     0x04  EP 4 OUT
        bmAttributes            2
          Transfer Type            Bulk
          Synch Type               None
          Usage Type               Data
        wMaxPacketSize     0x0040  1x 64 bytes
        bInterval               0

Commit 37939810b9 assumed that endpoint is
always interrupt type and changed usb_bulk_msg() calls to usb_interrupt_msg().

Problem here is that usb_bulk_msg() on interrupt endpoint selfcorrects the
call and changes requested pipe to interrupt type (see usb_bulk_msg).
However with usb_interrupt_msg() on bulk endpoint does not correct the
pipe type to bulk, but instead URB is submitted with interrupt type pipe.

So pre-2.6.39 used usb_bulk_msg() and therefore worked with both endpoint
types, however in 2.6.39 usb_interrupt_msg() with bulk endpoint causes
ohci_hcd to fail submitted URB instantly with -ENOSPC and preventing zd1211rw
from working with OHCI.

Fix this by detecting endpoint type and using correct endpoint/pipe types
for URB. Also fix asynchronous zd_usb_iowrite16v_async() to use right
URB type on 'EP 4 OUT'.

66870b1ccd wl12xx: fix oops in sched_scan when forcing a passive scan
Fix kernel oops when trying to use passive scheduled scans.  The
reason was that in passive scans there are no SSIDs, so there was a
NULL pointer dereference.

To solve the problem, we now check the number of SSIDs provided in the
sched_scan request and only access the list if there's one or more
(ie. passive scan is not forced).  We also force all the channels to
be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally
before the checks in the wl1271_scan_get_sched_scan_channels()
function.

71005be40a libertas: Set command sequence number later to ensure consistency
Before this patch, the command sequence number is being set before
lbs_queue_cmd() adds the command to the queue. However, lbs_queue_cmd()
sometimes forces commands to queue-jump (e.g. CMD_802_11_WAKEUP_CONFIRM).
It currently does this without considering that sequence numbers might need
adjusting to keep things running in order.

Fix this by setting the sequence number at a later stage, just before
we're actually submitting the command to the hardware. Also fixes a
possible race where seqnum was being modified outside of the driver
lock.

a9e1286975 rtlwifi: Fix kernel panic resulting from RX buffer allocation failure
To handle amsdu_8k capability, the PCI routine of this driver must
allocate receive buffers of order 2. Under heavy load, this causes
fragmentation of memory. The present code releases the current buffer
before checking to see if a new one is availble. Recovery from
allocation failures is not possible, which results in kernel panics.

The fix is to reorder the code to check that a new buffer can be
allocated before the old one is released. If not possible, the
received frame is dropped and the old one is reused. Without this
change, it is impossible to transfer a 2 GB file without a kernel panic.

21bc7af6e5 mwifiex: correct event header length
While decoding received event packet from firmware, 4 bytes
of interface header are already removed unconditionally.
So for handling event only 4 more bytes needs to be pulled.
This is achieved by changing event header length to 4.

Almost all the events, except BA stream related and AMSDU
aggregation control events, do not have the payload in their
event skb. Such events handling depends only on the event ID.
This event ID is the first four bytes of the event skb, which
is copied to a separate variable before pulling the skb header.
Hence event handling worked only for those events that didn't
have payload in event skb.

This patch fixes the broken event path of the events with
payload in their event skb without harming existing working
event path for the events without payload.

It occurs because we are able to change the slave configuarion of a bond while
the bond interface is down.  The bonding driver initializes some data structures
only after its ndo_open routine is called.  Among them is the initalization of
the alb tx and rx hash locks.  So if we add or remove a slave without first
opening the bond master device, we run the risk of trying to lock/unlock a
spinlock that has garbage for data in it, which results in our above softlock.

Note that sometimes this works, because in many cases an unlocked spinlock has
the raw_lock parameter initialized to zero (meaning that the kzalloc of the
net_device private data is equivalent to calling spin_lock_init), but thats not
true in all cases, and we aren't guaranteed that condition, so we need to pass
the relevant spinlocks through the spin_lock_init function.

Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to
the ndo_init path, so they are ready for use by the bond_store_slaves path.

Change notes:
v2) Based on conversation with Jay and Nicolas it seems that the ability to
enslave devices while the bond master is down should be safe to do.  As such
this is an outlier bug, and so instead we'll just initalize the errant spinlocks
in the init path rather than the open path, solving the problem.  We'll also
remove the warnings about the bond being down during enslave operations, since
it should be safe

v3) Fix spelling error

d10358de8d via-velocity: don't annotate MAC registers as packed
On ARM, memory accesses through packed pointers behave in unexpected
ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163
for discussion.

In this particular case, 32-bit I/O registers are accessed bytewise,
causing incorrect setting of the DMA address registers which in turn
leads to an error interrupt storm that brings the system to a halt.

Since the mac_regs structure does not need any packing anyway, this patch
simply removes the attribute to fix the issue.

a4910b7444 ehea: Fix multicast registration on semi-promiscuous mode
Ehea will not register multicast groups in phyp if the physical
interface is in promiscuous mode. But it should register if the
logical port is in promiscuous mode, but the physical port is not.

Ehea physical promiscuous mode is defined by ehea_port->promisc,
while logical port is defined by IFF_PROMISC.

So currently, if the user set the interface in promiscuous mode,
IGMP will not be registred in PHYP, and PHYP will never pass
the multicast packet to the logical port, which is bad

So, this patch just fixes it, assuring that we register in phyp
if the physical port is not on promiscuous mode.

8d8fc29d02 netpoll: disable netpoll when enslave a device
V3: rename NETDEV_ENSLAVE to NETDEV_JOIN

Currently we do nothing when we enslave a net device which is running netconsole.
Neil pointed out that we may get weird results in such case, so let's disable
netpoll on the device being enslaved. I think it is too harsh to prevent
the device being ensalved if it is running netconsole.

By the way, this patch also removes the NETDEV_GOING_DOWN from netconsole
netdev notifier, because netpoll will check if the device is running or not
and we don't handle NETDEV_PRE_UP neither.

This patch is based on net-next-2.6.

268bb0ce3e sanitize <linux/prefetch.h> usage
Commit e66eed651f ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h, which
uncovered several cases that had apparently relied on that rather
obscure header file dependency.

So this fixes things up a bit, using

   grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')
   grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]')

to guide us in finding files that either need <linux/prefetch.h>
inclusion, or have it despite not needing it.

There are more of them around (mostly network drivers), but this gets
many core ones.

d542fe27c8 tg3: Fix NETIF_F_LOOPBACK error
Mahesh Bandewar noticed that the features cleanup in commit
0da0606f49, entitled
"tg3: Consolidate all netdev feature assignments", mistakenly sets
NETIF_F_LOOPBACK by default.  This patch corrects the error.

449f454426 macvlan: remove one synchronize_rcu() call
When one macvlan device is dismantled, we can avoid one
synchronize_rcu() call done after deletion from hash list, since caller
will perform a synchronize_net() call after its ndo_stop() call.

Add a new netdev->dismantle field to signal this dismantle intent.

Reduces RTNL hold time.

In ad-hoc mode, beacon timers are configured differently compared to AP
mode, and (depending on the scenario) can vary enough to make the beacon
tasklet not detect slot 0 based on the TSF.
Since staggered beacons are not (and cannot be) used in ad-hoc mode, it
makes more sense to just hardcode slot 0 here, avoiding unnecessary
TSF reads and calculations.

ed9d01026f cfg80211: Use consistent BSS matching between scan and sme
cfg80211 scan code adds separate BSS entries if the same BSS shows up
on multiple channels. However, sme implementation does not use the
frequency when fetching the BSS entry. Fix this by adding channel
information to cfg80211_roamed() and include it in cfg80211_get_bss()
calls.

Please note that drivers using cfg80211_roamed() need to be modified to
fully implement this fix. This commit includes only minimal changes to
avoid compilation issues; it maintains the old (broken) behavior for
most drivers. ath6kl was the only one that I could test, so I updated
it to provide the operating frequency in the roamed event.

b1608d69cb drivercore: revert addition of of_match to struct device
Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.

e4abce8538 sfc: Use netif_device_{detach,attach}() around reset and self-test
We need to keep the TX queues stopped throughout a reset, without
triggering the TX watchdog and regardless of the link state.  The
proper way to do this is to use netif_device_{detach,attach}() just as
we do around suspend/resume, rather than the current bodge of faking
link-down.

Since we also need to do this during an offline self-test and we
perform a reset during that, add these function calls outside of
efx_reset_down() and efx_reset_up().

ebde6f8acb vmxnet3: Fix inconsistent LRO state after initialization
During initialization of vmxnet3, the state of LRO
gets out of sync with netdev->features.

This leads to very poor TCP performance in a IP forwarding
setup and is hitting many VMware users.

Simplified call sequence:
1. vmxnet3_declare_features() initializes "adapter->lro" to true.

2. The kernel automatically disables LRO if IP forwarding is enabled,
so vmxnet3_set_flags() gets called. This also updates netdev->features.

3. Now vmxnet3_setup_driver_shared() is called. "adapter->lro" is still
set to true and LRO gets enabled again, even though
netdev->features shows it's disabled.

Fix it by updating "adapter->lro", too.

The private vmxnet3 adapter flags are scheduled for removal
in net-next, see commit a0d2730c95
"net: vmxnet3: convert to hw_features".

Patch applies to 2.6.37 / 2.6.38 and 2.6.39-rc6.

34cecbbfad ixgbe: cleanup some minor issues in ixgbe_down()
This patch cleans up two minor issues in ixgbe_down.  Specifically it
addresses the fact that the VFs should not be pinged until after interrupts
are disabled otherwise they might still get a response.  It also drops the
use of the txdctl temporary variable since the only bit we should be
writing to the TXDCTL registers during a shutdown is the flush bit.

4ce7cc2b09 iwlagn: support multiple TBs per command
The current "huge" command handling is a bit
confusing, and very limited since only one
command may be huge at a time. Additionally,
we often copy data around quite pointlessly
since we could instead map the existing scan
buffer for example and use it directly.

This patch makes that possible. The first
change is that multiple buffers may be given
to each command (this change was prepared
earlier so callsites don't need to change).
Each of those can be mapped attached to a TB
in the TFD, and the command header can use a
TB (the first one) in the TFD as well.

Doing this allows getting rid of huge commands
in favour of mapping existing buffers. The
beacon transmission is also optimised to not
copy the SKB at all but use multiple TBs.

bc76b94051 wl12xx: Don't filter beacons that include changed HT IEs
This patch adds a beacon filter rule to pass up the beacons that
contain changed HT information elements.  These beacons need to be
passed to mac80211 so that it can act on such changes.

889cb360b4 wl12xx: simplify wl1271_ssid_set()
Simplify wl1271_ssid_set by re-using cfg80211_find_ie instead of
reimplementing it.

Additionally, add a length check to prevent a potential buffer overflow.

2592a73540 ne-h8300: Fix regression caused during net_device_ops conversion
Changeset dcd39c9029 ("ne-h8300: convert to
net_device_ops") broke ne-h8300 by adding 8390.o to the link. That
meant that lib8390.c was included twice, once in ne-h8300.c and once in
8390.c, subject to different macros. This patch reverts that by
avoiding the wrappers in 8390.c.

Fix based on commits 217cbfa856 ("mac8390:
fix regression caused during net_device_ops conversion") and
4e0168fa48 ("mac8390: fix build with
NET_POLL_CONTROLLER").
