Emmanuel Grumbach 203566f359 iwlwifi: add possibility to disable tx_power calibration
This patch adds the possibility to disable the tx_power calibration.
In 5000 HW, this calibration is implemented in uCode, hence, it is
disabled in driver by default.

Emmanuel Grumbach 4e39317df0 iwlwifi: clean up in setup/cancel deferred work
This patch makes some clean up in setup/cancel_deferred_work.
iwl_setup_deferred_work does the work that is common to 4965
and 5000, then it calls to HW specific handlers.

This patch also removes uneeded work_struct from iwl_priv.

This patch removes the possibility not to compile the run time
calibrations. It also renames priv->sensitivity_work to
priv->run_time_calib_work, and moves bg_run_time_calib to iwl4965_base
since it is common to both: 4965 and 5000.

Gertjan van Wingerde a9f853ddd3 rt2x00: Rework alignment check.
Rework the alignment check in rt2x00dev.c to be independent of any
potential alignment measures that may be taken before. Just check
whether the payload is aligned based on the pointer addresses.

Note: This is preparatory for the dynamically mapped skb buffers
for the PCI drivers, as these need 4-byte alignment instead of the
currently enforced offset by 2 bytes.

Gertjan van Wingerde a26cbc6508 rt2x00: Fix double usage of skb->cb in USB RX path.
It is not safe to use the skb->cb area for both the rxd and
skb_frame_desc data at the same time, while they occupy an overlapping
piece of memory. This can lead to hard to trace crashes as pointers
within skb_frame_desc are pointing into nowhere, or the rxd data is
overwritten with non-sense.

Fix it by copying the rxd to a small buffer on the stack.

Gertjan van Wingerde 239c249d06 rt2x00: Centralize RX packet alignment handling in rt2x00lib.
When rt2x00pci will be switched over to dynamically mapped skb's
instead of statically allocated DMA buffers, it no longer can handle
alignment of RX packets in a copy step, and needs to implement the
same scheme as rt2x00usb does.

In order to make the patch on dynamically mapped skb's smaller,
already centralize the alignment handling into rt2x00lib. This allows
us to move more code in rt2x00lib, and thus remove code duplication
between rt2x00usb and rt2x00pci.

Ivo van Doorn b869767b6f rt2x00: Don't kick TX queue after each frame
TX queues shouldn't be kicked after each frame that is put into the
queue.  This could cause problems during RTS and CTS-to-self as well
as with fragmentation. In all those cases you want all frames to be
send out in a single burst. Off course we shouldn't let the queue fill
up entirely, thus we introduce a 10% threshold which, when reached,
will force the frames to be send out regardless of the frame.

In addition we should prevent queues to become full in such a way
that the tx() handler can fail. Instead of stopping the queue when
it is full, we should stop it when it is below the threshold.

Ivo van Doorn 9dad92b9ba rt2x00: Calculate register offset during compile time
By using __ffs() the register offsets were always calculated
at run-time which all FIELD32/FIELD16 definitions were builtin
constants. This means we can heavily optimize the register handling
by allowing GCC to do all the work during compilation.

Add some compile_ffs() macros to perform the calculation at
compile time. After this each rt2x00 module size is reduced
by ~2500 bytes. And the stack size of several functions is reduced
as well which further limits the number of rt2x00 results in
'make checkstack'.

      instead of providing it as seperate patch.

bug in rt73usb which was caused by killing the guardian_urb
while it had never been allocated for rt73usb.

David S. Miller 4bb073c0e3 net: Eliminate flush_scheduled_work() calls while RTNL is held.
If the RTNL is held when we invoke flush_scheduled_work() we could
deadlock.  One such case is linkwatch, it is a work struct which tries
to grab the RTNL semaphore.

The most common case are net driver ->stop() methods.  The
simplest conversion is to instead use cancel_{delayed_}work_sync()
explicitly on the various work struct the driver uses.

This is an OK transformation because these work structs are doing
things like resetting the chip, restarting link negotiation, and so
forth.  And if we're bringing down the device, we're about to turn the
chip off and reset it anways.  So if we cancel a pending work event,
that's fine here.

Some drivers were working around this deadlock by using a msleep()
polling loop of some sort, and those cases are converted to instead
use cancel_{delayed_}work_sync() as well.

Holger Schurig a01f545040 libertas: fix sleep confirmation
This fixes an issus that made "iwconfig eth1 power on" non-working.
When we get a "PS sleep" event, we have to confirm this to the firmware.
The confirm happens with a command, but this command is special: the
firmware won't send us a response. if_cs_host_to_card() is setting
priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and
was never cleared back.

Now I put the special knowledge that the CMD_802_11_PS_MODE with
CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly
clearing the dnld_sent state in lbs_send_confirmsleep().

Dan Williams ea177305b3 ipw2200: queue direct scans
When another scan is in progress, a direct scan gets dropped on the
floor.  However, that direct scan is usually the scan that's really
needed by userspace, and gets stomped on by all the broadcast scans the
ipw2200 driver issues internally.  Make sure the direct scan happens
eventually, and as a bonus ensure that the passive scan worker is
cleaned up when appropriate.

The change of request_passive_scan form a struct work to struct
delayed_work is only to make the set_wx_scan() code a bit simpler, it's
still only used with a delay of 0 to match previous behavior.

Scott Ashcroft 20ad4fd562 rndis_wlan: use ARRAY_SIZE instead of sizeof when adding 11g rates
While figuring out the TKIP problem I found a bug in the code which adds the 11g
rates. It's using sizeof instead of ARRAY_SIZE to terminate the for loop. This makes
it fall off the end of the rates array start into the frequency array instead. Running
"iwlist rate" should show the problem as there will always be 32 rates with the last
few being bogus.

The following patch will fix it.

David Woodhouse 75bf45a7b4 libertas: fix multicast filtering on eth and msh interfaces
We weren't properly handling multicast on the mesh interface. Fix that,
which involves setting up the hardware to use the union of dev->mc_list
for both eth%d and msh%d devices.

This means we can't do it directly from ->set_multicast_list() because
we'd need to lock the other device to read its list, and we can't do
that because it might deadlock. So punt the actual work to keventd.

Also, invoke the same when taking an interface down; for some reason the
core calls ->set_multicast_list while IFF_UP is still set in dev->flags
when we're taking it down, so its addresses don't get removed then.

We also convert MAC_MULTICAST_ADR to a direct command while we're at it,
removing one more entry from the big switch statement in the deprecated
lbs_prepare_and_send_command() function.

Overall having the descriptor in front of the frame is a bad idea,
we can however use the skb->cb array for this task, since that

Gertjan van Wingerde 61448f8807 rt2x00: Fix queue related oops in case of deselected mac80211 multi-queue feature.
With the integration of the mac80211 multiqueue patches it has become possible that the
mac80211 layer modifies the number of TX queues that is stored inside the ieee80211_hw
structure, especially when multi-queue is not selected.

The rt2x00 drivers are not well suited to handle that situation, as they allocate the
queue structures before mac80211 has modified the number of queues it is going to use,
and also expect the number of allocated queues to match the hardware implementation.

Hence, ensure that rt2x00 maintains by itself the number of queues that the hardware
supports, and, at the same time, making is not dependent on the preservation of contents
inside a mac80211 structure.

Ivo van Doorn fb55f4d1fa rt2x00: Fix TX status reporting
The tx_status enumeration was broken since the introduction
of rt61pci. That driver uses different values to report the
status of the tx action.
This would lead to frames that were reported as success but
actually failed to be send out, or frames that were neither
successfull or failure which were reported as failure.

Fix this by change the TX status reporting and more explicitely
check for failure or success. Note that a third possibility is
added "unknown". Not all hardware (USB) can report the actual
TX status, for rt61pci some frames will receive this status
because the TXdone handler is never called for those frames.
This unknown will now be handled as neither success or failure,
so we no longer increment the failure counter while this conclusion
could not be determined from the real status of the frame.

Brian Cavagnolo 02969d296e libertas: fix command timeout after firmware failure
This is a fix for OLPC ticket #6586: "SCAN command fails, timer doesn't
fire". In fact, the timer was firing; the problem was that the dnld_sent
state variable was not being updated after the timer expired, so
lbs_execute_next_command was not being called.

The 4-bit reversal flip_4bit is replaced with the bitrev helper
bitrev8 and a 4-bit shift.  The B43_WARN is moved to the location
where a register is read from for checking there.  The other caller
explicitly passes an array index which is guaranteed to be within range

Bob Copeland d6894b5be1 ath5k: Fix loop variable initializations
In ath5k_tasklet_rx, both status structures 'rxs' and 'rs' are
initialized at the top of the tasklet, but not within the loop.
If the loop is executed multiple times in the tasklet then the
variables may see changes from previous packets.

For TKIP, this results in 'Invalid Michael MIC' errors if two packets
are processed in the tasklet: rxs.flag gets set to RX_DECRYPTED by
mac80211 when it decrypts the first encrypted packet.  The subsequent
packet will have RX_DECRYPTED set upon entry to mac80211, so mac80211
will not try to decrypt it.

We currently initialize all but two fields in the structures, so fix
the other two.

Bruno Randolf 566bfe5a8b mac80211: use hardware flags for signal/noise units
trying to clean up the signal/noise code. the previous code in mac80211 had
confusing names for the related variables, did not have much definition of
what units of signal and noise were provided and used implicit mechanisms from
the wireless extensions.

this patch introduces hardware capability flags to let the hardware specify
clearly if it can provide signal and noise level values and which units it can
provide. this also anticipates possible new units like RCPI in the future.

for signal:

  IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
  IEEE80211_HW_SIGNAL_DB     - dB difference to unspecified reference point
  IEEE80211_HW_SIGNAL_DBM    - dBm, difference to 1mW

for noise we currently only have dBm:

  IEEE80211_HW_NOISE_DBM     - dBm, difference to 1mW

if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
to provide the maximum value (max_signal) it reports in order for applications
to make sense of the signal values.

i tried my best to find out for each driver what it can provide and update it
but i'm not sure (?) for some of them and used the more conservative guess in
doubt. this can be fixed easily after this patch has been merged by changing
the hardware flags of the driver.

Bill Moss 15dbf1b7b7 iwl3945: do not delay hardware scan if it is a direct scan
iwl3945 <---> mac80211 <----> wpa_supplicant <---> NetworkManager

When a hardware scan is completed and another scan is requested in less
than two seconds, iwlwifi will not do the second scan and will pass the
error code -EAGAIN back to mac80211 where it quickly dies. The error
code is not passed along to the calling program wpa_supplicant. After a
timeout, wpa_supplicant will just give up but it will not know why the
scan failed. This is a weakness in the design.

I ran into this issue when I was trying to figure out why it takes more
an a minute for NetworkManager to connect after Networking has been
disabled and then re-enabled. I found a good deal of unnecessary work
being done because mac80211 requests authentication when the interface
is not configured, the ANY mode. I created an experimental passive
(NOTANY) mode for mac80211 to eliminate this case. Then NetworkManager
became so fast that I ran into the iwlwifi 2 second delay next scan
issue which we are discussing.

The patch resolves the problem by bypassing the delay if the scan request
is a direct scan. It should do less harm to the hardware.

Johannes Berg 07346f81e8 mac80211: proper STA info locking
As discussed earlier, we can unify locking in struct sta_info
and use just a single spinlock protecting all members of the
structure that need protection. Many don't, but one of the
especially bad ones is the 'flags' member that can currently
be clobbered when RX and TX is being processed on different
CPUs at the same time.

Because having four spinlocks for different, mostly exclusive
parts of a single structure is overkill, this patch also kills
the ampdu and mesh plink spinlocks and uses just a single one
for everything. Because none of the spinlocks are nested, this
is safe.

It remains to be seen whether or not we should make the sta
flags use atomic bit operations instead, for now though this
is a safe thing and using atomic operations instead will be
very simple using the new static inline functions this patch
introduces for accessing sta->flags.

Since spin_lock_bh() is used with this lock, there shouldn't
be any contention even if aggregation is enabled at around the
same time as both requires frame transmission/reception which
is in a bh context.

This (or something like it) should be folded into the base patch to avoid

Johannes Berg dbabad0c9c zd1211rw: fix potential use-after-free bug
zd_mac_tx_to_dev() could potentially free the skb, or hand it off
to mac80211 which might free it. Hence, this code needs to get the
usb pointer out of skb->cb before handing it off to that function.

Ivo van Doorn b30cdfc517 rt2x00: Clean up error handling of PCI queue DMA allocation.
When, for some reason, the rt2x00pci module fails to allocate DMA memory for
the queues, it tries to undo the complete initialization of the PCI device,
including freeing of the irq. This results in the following error in dmesg, as
the irq hadn't been requested yet:

[  78.123456] Trying to free already-free IRQ 17

Fix this by implementing proper error handling code, instead of just using the
full uninitialization function.

Ivo van Doorn ed499983b8 rt2x00: Fix broken recover-on-error path
During initialization the initialize() callback function
in rt2x00pci and rt2x00usb will cleanup the mess they made.

rt2x00lib shouldn't call uninitialize because the callback function already
cleaned up _and_ the DEVICE_INITIALIZED isn't set which causes the
rt2x00lib_uninitialize() to halt directly anyway. All that is required
to be cleaned up by rt2x00lib is the queue, and that can be done by
calling rt2x00queue_uninitialize() directly.

Ivo van Doorn 7872089745 rt2x00: Don't use pskb_expand_head()
rt2x00pci allocates DMA for descriptor and data,
rt61pci doesn't use this for the beacon, but it can
use the descriptor part as temporary buffer instead
of using pskb_expand_head().
Using this temporary buffer is obviously much better
then reallocating the skb buffer...

At the same time we can set the data length for the
beacon queue at 0, to make sure no DMA is allocated for
data (but just for the descriptor).

* when removing the card while the card was scanning or associtating,
  it could happen that destroy_workqueue() stuck and didn't return.
* make sure the command function doesn't run while we remove the list
  of pending commands
* for still unknown reason, I had calls to lbs_stop_card() with
