rt2x00: Set IEEE80211_HW_REPORTS_TX_ACK_STATUS in rt2800
rt2800 already reports the tx ack status of each frame back to mac80211.
Advertise this by setting IEEE80211_HW_REPORTS_TX_ACK_STATUS for rt2800.
This allows some mac80211 features like frame loss notifications to work
with rt2800.

rt2800lib: fix wrong -128dBm when signal is stronger than -12dBm
This patch correct the type of variables containing the rssi
values read from the rxwi.
In function rt2800_agc_to_rssi() 3 variables (rssi0, rssi1, rss2)
defined as int was assigned a 16bit signed values as unsigned.
From a test with a hi-gain antenna I verified that the rxwi
contains signed rssi values in the range -13/+81 (inclusive)
with 0 as an error condition. In case of negative values a
condition is triggered and the function return -128dBm while
the signal is at its maximum. This patch correct the cast so
negative values are not treated as very high positive values
(ex. -13 does not become 243).

rt2x00: Make use of sta_add/remove callbacks in rt2800
This allows us to assign a WCID to each STA even for STAs without
crypto key.
To achieve this search for an unused WCID in the HW WCID table and
assign it to the according STA. When configuring a pairwise key for this
STA we don't need to write the MAC address and BSSIDX anymore but just
update the crypto related fields in the WCID_ATTR table.
This has two advantages:
1) Setting a new key for an already available STA (PTK rekeying) is
slightly less expensive and should improve performance in situations
where a lot of rekeying happens (e.g. a huge number of stations and/or
a small rekeying interval)
2) The TXWI now gets a WCID assigned for unencrypted frames which will
be reflected in the corresponding tx status report. This should make tx
status reports in unencrypted AP mode more reliable as we can
distinguish between multiple key-less STAs.

Hence, remove the blink callback. This will result in software emulation

rt2800usb: read TX_STA_FIFO asynchronously
Trying to fix the "TX status report missed" warnings
by reading the TX_STA_FIFO entries as quickly as possible.
The TX_STA_FIFO is too small in hardware, thus reading
it only from the workqueue is too slow and entries get lost.
Start an asynchronous read of the TX_STA_FIFO directly from
the TX URB completion callback (atomic context, thus it cannot
use the blocking rt2800_register_read()). If the async
read returns a valid FIFO entry, it is pushed into a larger
FIFO inside struct rt2x00_dev, until rt2800_txdone() picks
it up.
A .tx_dma_done callback is added to struct rt2x00lib_ops
to trigger the async read from the URB completion callback.

rt2x00: Split rt2x00dev->flags
The number of flags defined for the rt2x00dev->flags field,
has been growing over the years. Currently we are approaching
the maximum number of bits which are available in the field.
A secondary problem, is that one part of the field are initialized only
during boot, because the driver requirements are initialized or device
requirements are loaded from the EEPROM. In both cases, the flags are
fixed and will not change during device operation. The other flags are
the device state, and will change frequently. So far this resulted in the fact
that for some flags, the atomic bit accessors are used, while for the others
the non-atomic variants are used.
By splitting the flags up into a "flags" and "cap_flags" we can put all flags
which are fixed inside "cap_flags". This field can then be read non-atomically.
In the "flags" field we keep the device state, which is going to be read atomically.
This adds more room for more flags in the future, and sanitizes the field access methods.

rt2x00: Fix tx aggregation problems with some clients
Some clients seem to rely upon the reception of BlockAckReqs to flush
their rx reorder buffer. In order to fix aggregation for these clients
rt2x00 should send a BlockAckReq if the transmission of an AMPDU
subframe fails.
Introduce a new flag TXDONE_AMPDU to indicate that this is an AMPDU
subframe and pass IEEE80211_TX_STAT_AMPDU_NO_BACK to mac80211 if an
AMPDU subframe failed during transmission.
This fixes aggregation problems with Intel 5100 Windows STAs (and maybe

rt2x00: Fix rt2800 key assignment in multi bssid setups
When setting up multiple BSSIDs in AP mode on an rt2800pci device we
previously used the STAs AID to select an appropriate key slot. But
since the AID is per VIF we can end up with two STAs having the same AID
and thus using the same key index. This resulted in one STA overwriting
the key information of another STA.
Fix this by simply searching for the next unused entry in the pairwise
key table.
Also bring the key table init in sync with deleting keys by initializing
the key table entries to 0 instead of 1.

places where only tx queues are valid.
Furthermore, this new method is quite short and as such can be inlined
to avoid the function call overhead.

queue and the generic tx path.

rt2x00: Refactor beacon code to make use of start- and stop_queue
This patch allows to dynamically remove beaconing interfaces without
shutting beaconing down on all interfaces.
The only place to start and stop beaconing are now the start- and
stop_queue callbacks. Hence, we can remove some register writes during
interface bring up (config_intf) and only write the correct sync mode
to the register there.
When multiple beaconing interfaces are present we should enable
beaconing as soon as mac80211 enables beaconing on at least one of
them. The beacon queue gets stopped when the last beaconing
interface was stopped by mac80211. Therefore, introduce another
interface counter to keep track ot the number of enabled beaconing
interfaces and start or stop the beacon queue accordingly.
To allow single interfaces to stop beaconing, add a new driver
callback clear_beacon to clear a single interface's beacon without
affecting the other interfaces. Don't overload the clear_entry callback
for clearing beacons as that would introduce additional overhead
(check for each TX queue) into the clear_entry callback which is used
on the drivers TX/RX hotpaths.
Furthermore, the write beacon callback doesn't need to enable beaconing
anymore but since beaconing should be disabled while a new beacon is
written or cleared we still disable beacon generation and enable it
afterwards again in the driver specific callbacks. However, beacon
related interrupts should not be disabled/enabled here, that's solely
done from the start- and stop queue callbacks. It would be nice to stop
the beacon queue just before the beacon update and enable it afterwards
in rt2x00queue itself instead of the current implementation that relies
on the driver doing the right thing. However, since start- and
stop_queue are mutex protected we cannot use them for atomic beacon
updates.

mac80211: track receiver's aggregation reorder buffer size
The aggregation code currently doesn't implement the
buffer size negotiation. It will always request a max
buffer size (which is fine, if a little pointless, as
the mac80211 code doesn't know and might just use 0
instead), but if the peer requests a smaller size it
isn't possible to honour this request.
In order to fix this, look at the buffer size in the
addBA response frame, keep track of it and pass it to
the driver in the ampdu_action callback when called
with the IEEE80211_AMPDU_TX_OPERATIONAL action. That
way the driver can limit the number of subframes in
aggregates appropriately.
Note that this doesn't fix any drivers apart from the
addition of the new argument -- they all need to be
updated separately to use this variable!

rt2x00: Fix hw crypto in AP mode for some devices
The BSSID register shouldn't be set in AP mode on some older devices (like
rt73usb) as it breaks hw crypto on these. However, rt2800 devices explicitly
need the BSSID register set to the same value as our own MAC address (only
in AP mode).
Hence, don't set the BSSID from rt2x00lib but move it down into rt2800 to
avoid problems on older devices.
This fixes a regression (at least for rt73usb) and avoids a new regression
for rt2800 devices in 2.6.36.

rt2x00: Sync Tx and RX ring sizes with legacy drivers
All rt2x00 devices used the same Tx and Rx ring size (24 entries) till
now. Newer devices (like rt2800) can however make use of a larger TX and
RX ring due to 11n capabilities (AMPDUs of size 64 for example).
Hence, bring rt2x00 in sync with the legacy drivers and use the same TX
and RX ring sizes. Also remove the global defines RX_ENTRIES, TX_ENTRIES,
BEACON_ENTRIES and ATIM_ENTRIES and use per driver values.
That is 24 entries for rt2400pci, 32 entries for rt2500pci, rt2500usb,
rt61pci and rt73usb and 128 (RX) and 64 (TX) for rt2800pci and rt2800usb.

rt2x00: Work around hw aggregation oddity in rt2800
If a frame is not meant to be sent as AMPDU or part of it the hw might
still decide to aggregate this frame if a previous frame started an
AMPDU. However, this will limit the usefulness of the reported tx rate
since the reported rate will be the one specified in the TXWI of the
first frame and thus it is not possible to reliably caculate the
number of retrys by substracting the reported tx rate from the tx rate
in the TXWI.
To fix this issue, only report the successful rate for frames that were
not meant to be aggregated but ended up in an aggregate.
Example:
Frame A (MCS7, AMPDU=1) B (MCS7, AMPDU=1) C (MCS12, AMDPU=0, PROBE_RATE)
Although frame C shoudn't be aggregated the hw might sill put it
into an AMPDU together with A and B. If the transmission succeeds the tx
status will contain MCS7 for all three frames. In that case we should
only report MCS7 as success rate and avoid reporting MCS12-MCS8 as
failed tx attempts as this will affect the future rate control
decisions.
This oddity might strike us in other scenarious as well but the most
common "wrong" report happened for frames used to probe a different tx
rate.
This improves the rate control decisions notable.

rt2x00: Improve TX status entry validation
The TX_STA_FIFO contains some information for identifying
a outgoing frame, however matching by WCID and ACK status is
not sufficient to 100% identify the macthing queue_entry structure
(containing the SKB buffer) which belongs to the status report.
Within TX_STA_FIFO we have a 4-bit field named PACKETID, which is
currently used to encode the queue id. The queue ID is however
limited to values from 0 to 3, which means 2 bits are sufficient
to encode the value. With the remaining 2 bits we can encode a
partial queue_entry index number. The value of PACKETID is not
allowed to become 0, with the queue ID ranging from 0 to 3, at least
one of the bits for the entry identification must be 1.
That leaves us with 3 possible values we can still encode in the
bits. Altough this doesn't allow 100% accurate matching of the
TX_STA_FIFO queue to a queue_entry structure, it at least improves
the accuracy. This allows us to better detect if we have missed the
TX_STA_FIFO report, which in turn reduces the number of watchdog
warnings regarding the TX status timeout.

rt2x00: correctly set max_report_rates in rt61pci and rt2800
rt61pci and rt2800 devices can use up to 7 different rates per tx frame.
However, the device uses a global fallback table. Hence, the rc
algortihm cannot specify multiple rates to try but the device is able to
report multiple rates (based on the retry table). Specify that behavior
by correctly setting max_report_rates and max_rates.
This makes rt2x00 and minstrel play nicer together.

Since rt2x00 USB devices have no chance to know when a beacon was sent
out in AP mode currently all broad- and multicast traffic is buffered in

Unfortunately we have no chance in sending the traffic out after a
DTIM beacon due to hw limitations. Hence, instead of never sending the
buffered traffic out better send it out immediately.

This fixes an issue in AP mode where the beacon interval is not

rt2x00: Fix max TX power settings
During initialization each driver reads the default TX power
for each individual channel. However mac80211 only accepts the
maximum value (which is also handled as default value).
As a result, the TX power of the device was being limited to
the default value, which is often quite low compared to the
real maximum acceptable value.
This patch allows each driver to set the maximum value on a
per-channel basis which is forwarded to mac80211. The default
value will be preserved for now, in case we want to update
mac80211 to differentiate between the maximum and default txpower.
This fixes bug complaining about limited TX power values like:

was copied into the skb->cb where mac80211 would handle it further.
However at the moment only the fields current band, and frequency
were updated. Whereas the band was already provided directly within
the rt2x00_dev structure. Save a memcpy action, and reduce memory
a bit, by adding a curr_freq field to rt2x00_dev, and completely
remove the ieee80211_rx_status structure from rt2x00_dev.

rt2x00: Implement TX status reporting for rt2800usb
The TX_STA_FIFO register which is used for per-frame TX frame
status reporting is also valid on rt2800usb. We can move the
rt2800pci_txdone function into rt2800lib where it can also
be used by rt2800usb.
rt2800usb needs to overwrite the txdone work handler to
a different function.
Both rt2800usb as rt2800_txdone need to take into account
that IO failures can occur while uploading the URB, which
means that when obtaining the new entry the IO status must
be checked.

rt2x00: Request TXWI pointer from driver
The only reason why the write_tx_data callback function
is needed inside the driver, is because the location of
the TXWI descriptor is different on PCI and USB hardware.
Except for the beacon, where the TXWI is always at the
start of the SKB buffer.
In both cases the drivers write_tx_data function only
wrap around the function rt2800_write_txwi. Move write_tx_data
completely into the rt2800lib library, and add a callback
function to obtain the TXWI pointer.

rt2x00: Add missing TSF sync mode for AP operation
Currently rt2x00 uses the TSF_SYNC_BEACON mode for all beaconing
interface types. However, TSF_SYNC_BEACON is meant for IBSS networks and
thus implements TSF merging in the hardware. Rename TSF_SYNC_BEACON to
TSF_SYNC_ADHOC to better express its purpose and introduce the missing
TSF sync mode TSF_SYNC_AP_NONE which should be used for beaconing modes
that don't need TSF merging.

rt2x00: Convert AGC value from descriptor to RSSI (dBm)
The RSSI values in the RXWI descriptor aren't true RSSI
values. Instead they are more like the AGC values similar
to rt61pci. And as such, it needs the same conversion
before it can be passed to rt2x00lib/mac80211.
This requires the struct queue_entry to be passed to
rt2800_process_rxwi rather then the skb structure which
is contained in the queue_entry. This is required to
obtain the lna_gain information from the rt2x00_dev structure.
This fixes connection problems when using wpa_supplicant
which would try to connect to the worst AP's rather then the
best ones.

be overridden in the next switch statement, making this initialization
bogus. History of this line indicates it was there from the beginning,
and was once caught as typo. Instead of replacing the line with the

support the whole functionality.
As rt2800 has a global fallback table we cannot specify more then one tx rate
per frame but since the hw will try several different rates (based on the
fallback table) we should still initialize max_rates to the maximum number of
rates we are going to try. Otherwise mac80211 will truncate our reported tx
rates and the rc algortihm will end up with incorrect data choosing unsuitable
rates for tx.
This improves throughput on rt2800 devices considerable.

used for this chipset, rather then the rt2x array.
Furthermore RF3052 supports the 5GHz band, extend
the rt3x array with the 5GHz channels, and use them
for the RF3052 chip.

rt2x00: rt2800: don't overwrite SIFS values on erp changes
The SIFS value is a constant and doesn't need to be updated on erp changes.
Furthermore the code used 10us for both, the OFDM SIFS and CCK SIFS time
which broke CTS protected 11g connections (see patch "rt2x00: rt2800: update
initial SIFS values" for details).

rt2x00: rt2800: update initial SIFS values
Currently the CCK and OFDM SIFS value is set to 32us. This value is neither
used by the Ralink driver nor specified in 802.11.
Instead of using 10us for CCK SIFS (as defined in 802.11) use 16us like in the
Ralink drivers. And indeed using a SIFS value of 10us breaks connectivity with
11g + CTS protected connections. Add a comment to the code why we don't use 10us
for CCK SIFS value.
The OFDM SIFS value is set to 16us (as defined in 802.11 and also used by the
Ralink drivers).

rt2x00: rt2800lib: update rfcsr & bbp init code for SoC devices
Update the rfcsr and bbp init code for SoC devices to match with the
latest Ralink driver.
To have better control over which values are used for the register
initialization create a new function rt2800_is_305x_soc which checks
for SoC interface type, the correct RT chipset and the correct RF
chipset. This is based on the assumption that all rt305x SoC devices
use a rt2872 and rf3020/rf3021/rf3022.
In case an unknown RF chipset is found on a SoC device with a rt2872
don't treat it as rt305x and just print a message.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

rt2x00: Let rt2800lib check CONFIG_RT2X00_LIB_USB instead of CONFIG_RT2800USB
rt2800lib currently checks whether RT2800USB is enabled in the configuration.
Strictly speaking this is not necessary, it only needs to know whether the
generic rt2x00usb library functions are available. Therefore check for
RT2X00_LIB_USB instead.

mac80211: fix peer HT capabilities
I noticed yesterday, because Jeff had noticed
a speed regression, cf. bug
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2138
that the SM PS settings for peers were wrong.
Instead of overwriting the SM PS settings with
the local bits, we need to keep the remote bits.
The bug was part of the original HT code from
over two years ago, but unfortunately nobody
noticed that it makes no sense -- we shouldn't
be overwriting the peer's setting with our own
but rather keep it intact when masking the peer
capabilities with our own.
While fixing that, I noticed that the masking of
capabilities is completely useless for most of
the bits, so also fix those other bits.
Finally, I also noticed that PSMP_SUPPORT no
longer exists in the final 802.11n version, so
also remove that.

rt2x00: Disable powersaving for rt61pci and rt2800pci.
We've had many reports of rt61pci failures with powersaving enabled.
Therefore, as a stop-gap measure, disable powersaving of the rt61pci
until we have found a proper solution.
Also disable powersaving on rt2800pci as it most probably will show
the same problem.

drivers/net/wireless: Correct code taking the size of a pointer
sizeof(iv16) and sizeof(iv32) are the sizes of pointers. Change them to
the size of the copied data.
Furthermore, iveiv_entry is a local structure that has just been
initialized and is not visible outside this function. Thus, there would
seem to be no point to copy data into it. The order of the arguments is
thus changed to copy the data into the parameters, which are provided as
pointers, suggesting in this case that they should be used to return values.
A simplified version of the semantic patch that finds the first problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression *x;
expression f;
type T;
@@
*f(...,(T)x,...)

rt2800: do not enable tbtt unless we are in a beacon mode
Please be gentle, I'm a fs developer and this is my first foray into drivers, as
I'm tired of building ralinks driver everytime I update my kernel. Whenever I
load the rt2800pci driver my box bogs down, and a few printk's later I
discovered its because I was getting 10's of thousands of TBTT interrupts a
second. I discovered this was because we were setting the beacon timer to 0,
which is apparently what TBTT keys off of. It seems to me that we should only
be enabling TBTT when we are in a beacon transmitting mode, which from what I
can tell is in AD-HOC and other such modes where the mac80211 layer would have
given us a proper beacon_int to set the beacon timer to instead of 0. So this
is my fix, only enable TBTT if our sync mode is for beacon. This makes it so my
box doesn't die everytime I load the rt2800pci driver. Let me know if this is
acceptable, I just learned all these terms about 15 minutes ago via wikipedia,
so I really am not familiar with how this stuff is supposed to work. Thanks,

rt2x00: Fix BUG on rt2800usb when trying to read eFuse EEPROM.
Current tree hits a BUG_ON in rt2x00_regbusy_read, because the eFuse EEPROM
reading code of rt2800lib uses the function without the csr_mutex locked.
Fix this by locking the csr_mutex for the of the EEPROM reading cycly and
using the _lock variants of the register reading and writing functions.
This also introcudes the register_read_lock function pointer in the
rt2800_ops structure.

rt2x00: Log RT/RF chipset information correctly.
Some drivers (rt2800* most notably) cannot set the RF and RT chipset in
the correct order to have the information logging in rt2x00_set_chip
be correct.
Fix this by decoupling the setting of the chipset information from the
logging of the chipset information so that drivers can determine
themselves when all information is set.
