Eliad Peller f795ea8b2f wl12xx_sdio: declare support for NL80211_WOW_TRIGGER_ANYTHING trigger
Since wowlan requires the ability to stay awake while the host
is suspended, declare support for NL80211_WOW_TRIGGER_ANYTHING
if the MMC_PM_KEEP_POWER capability is being supported.

Eliad Peller f44e58681a wl12xx: prevent scheduling while suspending (WoW enabled)
When WoW is enabled, the interface will stay up and the chip will
be powered on, so we have to flush/cancel any remaining work, and
prevent the irq handler from scheduling a new work until the system
is resumed.

Add 2 new flags:
* WL1271_FLAG_SUSPENDED - the system is (about to be) suspended.
* WL1271_FLAG_PENDING_WORK - there is a pending irq work which
   should be scheduled when the system is being resumed.

In order to wake-up the system while getting an irq, we initialize
the device as wakeup device, and calling pm_wakeup_event() upon
getting the interrupt (while the system is about to be suspended)

Ben Hutchings 747df2258b sfc: Always map MCDI shared memory as uncacheable
We enabled write-combining for memory-mapped registers in commit
65f0b417de, but inhibited it for the
MCDI shared memory where this is not supported.  However,
write-combining mappings also allow read-reordering, which may also
be a problem.

I found that when an SFC9000-family controller is connected to an
Intel 3000 chipset, and write-combining is enabled, the controller
stops responding to PCIe read requests during driver initialisation
while the driver is polling for completion of an MCDI command.  This
results in an NMI and system hang.  Adding read memory barriers
between all reads to the shared memory area appears to reduce but not
eliminate the probability of this.

We have not yet established whether this is a bug in our BIU or in the
PCIe bridge.  For now, work around by mapping the shared memory area
separately.

Amitkumar Karwar 7cc5eb629c mwifiex: remove unnecessary struct mwifiex_opt_sleep_confirm_buffer
The structure definition is
struct mwifiex_opt_sleep_confirm_buffer {
       u8 hdr[4];
       struct mwifiex_opt_sleep_confirm ps_cfm_sleep;

For sleep_confirm command we already reserve 4 bytes (using skb_reserve())
for an interface header. It will be filled later by interface specific code.
We don't need "hdr[4]" element in above structure. So we can use
"struct mwifiex_opt_sleep_confirm" directly instead of

With driver rtl8192de, the sizes will be 256 and 256 * 4 respectively. As that

Johannes Berg 054ec92494 iwlagn: fix iwl_is_any_associated
The function iwl_is_any_associated() was intended
to check both contexts, but due to an oversight
it only checks the BSS context. This leads to a
problem with scanning since the passive dwell
time isn't restricted appropriately and a scan
that includes passive channels will never finish
if only the PAN context is associated since the
default dwell time of 120ms won't fit into the
normal 100 TU DTIM interval.

Fix the function by using for_each_context() and
also reorganise the other functions a bit to take
advantage of each other making the code easier to
read.

That commit claim that mac80211 will not use non-IBSS channel in IBSS

temporally, and provide proper mac80211 fix latter.

Mohammed Shafi Shajakhan 99aa55b66e ath9k: Fix a warning due to a queued work during S3 state
during suspend/S3 state drv_flush is called from mac80211 irrespective of
interface count. In ath9k we queue a work in ath9k_flush which we expect
to be cancelled in the drv_stop call back. during suspend process mac80211
calls drv_stop only when the interface count(local->count) is non-zero.
unfortunately when the network manager is enabled, drv_flush is called
while drv_stop is not called as local->count reaches '0'.
	So fix this by simply checking for the device presence in the
drv_flush call back in the driver before queueing work or anything else.

Francois Romieu 56de414c0c r8169: remove non-NAPI context invocation of rtl8169_rx_interrupt.
Invocation of rtl8169_rx_interrupt from rtl8169_reset_task was originally
intended to retrieve as much packets as possible from the rx ring when a
reset was needed. Nowadays rtl8169_reset_task is only scheduled, with
some delay
a. from the tx timeout watchdog
b. when resuming
c. from rtl8169_rx_interrupt itself

It's dubious that the loss of outdated packets will matter much for a)
and b). c) does not need to call itself again.

Francois Romieu 4876cc1e49 r8169: link speed selection timer rework.
The implementation was a bit krusty.

The 10s rtl8169_phy_timer timer has been (was ?) required with older
8169 for adequate phy operation when full gigabit is advertised in
autonegotiated mode. The timer does nothing if the link is up.
Otherwise it keeps resetting the phy until things improve.

- the device private data field phy_1000_ctrl_reg was used to
  schedule the timer. Avoid it and save a few bytes.

- rtl8169_set_settings
  pending timer is disabled before changing the link settings as
  rtl8169_phy_timer is not always needed (see the removed test in
  rtl8169_phy_timer).

- rtl8169_set_speed
  the requested link parameters may not match the chipset : bail out
  early on failure.

- rtl8169_open
  Calling rtl8169_request_timer is redundant with
  -> rtl8169_open
     -> rtl8169_init_phy
        -> rtl8169_set_speed
           -> mod_timer
  The latter always enables the phy timer whereas the former did not
  for RTL_GIGA_MAC_VER_01. It should not make things worse but only
  time will tell if reality agrees.

- rtl8169_request_timer : unused yet. Removed.

- rtl8169_delete_timer : useless. Bloat. Removed.

Side effect : the timer may kick in if the TBI is enabled. I do not
know if the TBI has ever been used in real life.

Francois Romieu 826e6cbdad r8169: rtl8169_set_speed_xmii cleanup.
Shorten chipset version test.

No functional change.

Careful readers will notice that the 'supports_gmii' flag is deduced
from the device PCI id. Though less specific than the chipset related
RTL_GIGA_MAC_VER_XY, it is good enough to detect a GMII deprieved 810x.
Some features push for a device specific configuration (improved jumbo
frame support for instance). 'supports_gmii' will follow this path
if / when the device PCI id test stops working.

Eric Dumazet 226bd34114 net: use batched device unregister in veth and macvlan
veth devices dont use the batched device unregisters yet.

Since veth are a pair of devices, it makes sense to use a batch of two
unregisters, this roughly divides dismantle time by two.

Fix this by changing dellink() callers to always provide a non NULL
head. (Idea from Michał Mirosław)

This patch also handles macvlan case : We now dismantle all macvlans on
top of a lower dev at once.

Mahesh Bandewar eed2a12f1e net: Allow ethtool to set interface in loopback mode.
This patch enables ethtool to set the loopback mode on a given interface.
By configuring the interface in loopback mode in conjunction with a policy
route / rule, a userland application can stress the egress / ingress path
exposing the flows of the change in progress and potentially help developer(s)
understand the impact of those changes without even sending a packet out
on the network.

Following set of commands illustrates one such example -
    a) ip -4 addr add 192.168.1.1/24 dev eth1
    b) ip -4 rule add from all iif eth1 lookup 250
    c) ip -4 route add local 0/0 dev lo proto kernel scope host table 250
    d) arp -Ds 192.168.1.100 eth1
    e) arp -Ds 192.168.1.200 eth1
    f) sysctl -w net.ipv4.ip_nonlocal_bind=1
    g) sysctl -w net.ipv4.conf.all.accept_local=1
    # Assuming that the machine has 8 cores
    h) taskset 000f netserver -L 192.168.1.200

Ben Hutchings 9c412942a0 ipheth: Properly distinguish length and alignment in URBs and skbs
The USB protocol this driver implements appears to require 2 bytes of
padding in front of each received packet.  This used to be equal to
the value of NET_IP_ALIGN on x86, so the driver abused that constant
and mostly worked, but this is no longer the case.  The driver also
mixed up the URB and packet lengths, resulting in 2 bytes of junk at
the end of the skb.

Introduce a private constant for the 2 bytes of padding; fix this
confusion and check for the under-length case.

Roland Dreier e328d41082 vmxnet3: Consistently disable irqs when taking adapter->cmd_lock
Using the vmxnet3 driver produces a lockdep warning because
vmxnet3_set_mc(), which is called with mc->mca_lock held, takes
adapter->cmd_lock.  However, there are a couple of places where
adapter->cmd_lock is taken with softirqs enabled, lockdep warns that a
softirq that tries to take mc->mca_lock could happen while
adapter->cmd_lock is held, leading to an AB-BA deadlock.

I'm not sure if this is a real potential deadlock or not, but the
simplest and best fix seems to be simply to make sure we take cmd_lock
with spin_lock_irqsave() everywhere -- the places with plain spin_lock
just look like oversights.

The full enormous lockdep warning is:

 =========================================================
 [ INFO: possible irq lock inversion dependency detected ]

 but this lock took another, SOFTIRQ-unsafe lock in the past:
  (&(&adapter->cmd_lock)->rlock){+.+...}

 and interrupts could create inverse lock ordering between them.

 other info that might help us debug this:

TX checksumming support has been ifdef commented out of this driver
for more than 10 years, and it makes references to aspects of the IPv4
stack from back then as well.

If someone has one of these rare cards and wants to properly resurrect
TX checksumming support, they can still get at this code in the

Cindy H. Kao 4613e72dbd iwlwifi: support the svtool messages interactions through nl80211 test mode
This patch adds the feature to support the test mode operation through
the generic netlink channel NL80211_CMD_TESTMODE between intel
wireless device iwlwifi and the user space application svtool.

The main purpose is to create a transportation layer between the iwlwifi
device and the user space application so that the interaction between the
user space application svtool and the iwlwifi device in the kernel space is
in a way of generic netlink messaging.

The detail specific functions are:

1. The function iwl_testmode_cmd() is added to digest the svtool test command
   from the user space application. The svtool test commands are categorized  to
   three types : commands to be processed by the device ucode, commands to access
   the registers, and commands to be processed at the driver level(such as reload
   the ucode). iwl_testmode_cmd() dispatches the commands the corresponding handlers
   and reply to user space regarding the command execution status. Extra data is
   returned to the user space application if there's any.

2. The function iwl_testmode_ucode_rx_pkt() is added to multicast all the spontaneous
   messages from the iwlwifi device to the user space. Regardless the message types,
   whenever there is a valid spontaneous message received by the iwlwifi ISR,
   iwl_testmode_ucode_rx_pkt() is invoked to multicast the message content to user
   space. The message content is not attacked and the message parsing is left to
   the user space application.

Implementation guidelines:

1. The generic netlink messaging for iwliwif test mode is through  NL80211_CMD_TESTMODE
   channel, therefore, the codes need to follow the regulations set by cfg80211.ko
   to get the actual device instance ieee80211_ops via cfg80211.ko, so that the iwlwifi
   device is indicated with ieee80211_ops and can be actually accessed.

   Therefore, a callback iwl_testmode_cmd() is added to the structure
   iwlagn_hw_ops in iwl-agn.c.

2. It intends to utilize those low level device access APIs from iwlwifi device driver
   (ie. iwlagn.ko) rather than creating it's own set of device access functions.
   For example, iwl_send_cmd(), iwl_read32(), iwl_write8(), and iwl_write32() are reused.

3. The main functions are maintained in new files instead of spreading all over the
   existing iwlwifi driver files.

   The new files added are :

   drivers/net/wireless/iwlwifi/iwl-sv-open.c
        - to handle the user space test mode application command
          and reply the respective command status to the user space application.
        - to multicast the spontaneous messages from device to user space.

   drivers/net/wireless/iwlwifi/iwl-testmode.h
        - the commonly referenced definitions for the TLVs used in
          the generic netlink messages

IV when HW crypto is being used. Instead only reserve
appropriate space in tx skb's in the driver, so that the
firmware can write IV's values.

Luis R. Rodriguez cf3a03b9c9 ath9k_hw: fix power for the HT40 duplicate frames
With AR9003 at about ~ 10 feet from an AP that uses RTS / CTS you
will be able to associate but not not get data through given that
the power for the rates used was set too low. This increases the
power and permits data connectivity at longer distances from
access points when connected with HT40. Without this you will not
get any data through when associated to APs configured in HT40
at about more than 10 feet away.

Patch:
  rt2x00: Make rt2x00_queue_entry_for_each more flexible
  commit: 10e11568ca

introduced a severe regression on the throughput
for USB hardware. It turns out that the exiting of
the rt2x00queue_for_each_entry() was done too early.

The exact cause for this regression is unknown,
but by disabling the premature exiting of the loop
seems to resolve the issue.

invalid nf readings on extn chains and these invalid values
got updated into history buffer. While loading those values
from history buffer is moving the chip to deaf state.

This issue was observed in AR9002/AR9003 chips while doing
associate/dissociate in HT40 mode and interface up/down
in iterative manner. After some iterations, the chip was moved
to deaf state. Somehow the pci devices are recovered by poll work
after chip reset. Raading the nf values in all supported extension chains
when the hw is not yet configured in HT40 mode results invalid values.

Nicolas Cavallari 8f7f3b2fcc carl9170: fix allmulticast mode
Currently, the driver only disable multicast filtering when the
FIF_ALLMULTI driver flag has been just set (ie,
if changed_flags& FIF_ALLMULTI and *new_flags& FIF_ALLMULTI) or else
it will reenable multicast filtering.

But next time, this condition will be false and multicast filtering
will be reenabled, even through FIF_ALLMULTI is still set.

This mean that allmulticast only works for less than two minutes in
ad-hoc mode.  This patch fixes that to disable multicast filtering
as long as FIF_ALLMULTI is set.

Amitkumar Karwar 57f16b5da0 mwifiex: fix simultaneous assoc and scan issue
When scan and assoc (infra/ibss) commands are simultaneously
given in two terminals, association response is erroneously
served while serving the scan response.

mwifiex_cfg80211_results() is the common routine for sending
ioctl (scan, assoc etc.) results to cfg80211 stack. In above
scenario even if the common routine is called for scan ioctl
context, it also tries to send information about assoc ioctl to
cfg80211 because "priv->assoc_request/priv->ibss_join_request"
flag is on at that time.

Fix the issue by updating request variable after assoc handling
and modifying the variable check in mwifiex_cfg80211_results.

Daniel Drake 7e4b4eeced libertas: remove tx_timeout handler
As described at http://marc.info/?l=linux-netdev&m=130428493104730&w=2
libertas frequently generates spurious tx timeouts, because the tx
queue is brought down for extended periods during scanning. The net
layer takes a look and incorrectly assumes the queue has been down for
several seconds, and generates a tx_timeout.

One way to fix this is to bump the trans_start counter while scanning
so that the network layer knows that the device is still alive, but
I think the tx_timeout handler is implemented wrongly here and not of
any real use, so I vote to remove it.

As explained at http://marc.info/?l=linux-wireless&m=130430311115755&w=2
the watchdog is primarily meant to deal with lockup on the hardware TX
path (detected by the tx queue being stopped for an extended period of
time), but this is unlikely to happen with libertas. In this case, the tx
queue is stopped only while waiting for lbs_thread to send the queued frame
to the driver, and lbs_thread wakes up the queue immediately after, even
if the frame could not be sent correctly.

So, the only hardware-related possibility that this catches is if
hw_host_to_card hangs - this is something I have never seen. And if it
were to happen, nothing done by lbs_tx_timeout would actually wake up
lbs_thread any quicker than otherwise.

Removing this oddly-behaving spuriously-firing tx_timeout handler should
fix an occasional kernel crash during resume
(http://dev.laptop.org/ticket/10748)
