Subject: iwlwifi: validate enhanced tx power entry

Validate enhanced tx power entry read from EEPROM before applying the
tx power value. Different versions of EEPROM might contain different size
of table; always a good idea to make sure the entry is valid before
applying to the targeted channel.

Subject: iwlwifi: update reply_statistics_cmd with 'clear' parameter

When issue REPLY_STATISTICS_CMD to uCode, two possible flag
can be set in the configuration flags

bit 0: Clear statistics
       0: Do not clear Statistics counters
       1: Clear to zero Statistics counters

Allow "clear" parameter to be set from the caller.

Add debugfs file to clear the statistics counters to help monitor and
debug the uCode behavior.

Subject: iwl3945: Reset saved POWER_TABLE_CMD in "up"

Power-saving logic will not re-issue a POWER_TABLE_CMD if a new command
matches the prior one.  This can be bad if we re-start the device due to
e.g. uCode error; the new POWER_TABLE_CMD (required to invoke power-saving)
may match the prior POWER_TABLE_CMD issued before the uCode error.

Ensure the POWER_TABLE_CMD is sent to device when uCode is up.

Subject: iwlwifi: eliminate the possible 1/2 dBm tx power loss in 6x00 & 6x50
 series

In both 6x00 and 6x50 series, the enhanced/extended tx power table in
EEPROM is used to set the max. tx power limit.
This new tx power table is in 1/2 dBm format, which creates an issue of
possibility of 1/2 dBm loss when driver set the tx power limit; because
of driver keep track and report the tx power in dBm format.

In order to prevent the 1/2 dBm loss, keep track of the true max tx
power in 1/2 dBm format in driver; do the comparison and adjust the tx
power if needed when send tx power command to uCode.

Subject: iwlagn: power up device before initializing EEPROM

A recent change optimized the power usage by the device by only powering it
up during EEPROM load if it is required (for OTP devices). This change causes
an error on the 1000 series devices during module load.

The error looks as follows:
[ 1624.024524] iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kds

Adding a dump_stack() to where that error is printed shows the following:

We know that the routines in this trace, iwlcore_eeprom_acquire_semaphore
and iwlcore_eeprom_verify_signature, only access CSR registers and thus do
not need the device to be awake if it is EEPROM. But for OTP it is required
for the device to be awake to read these registers. Ensure device is awake
before accessing these registers.

Subject: iwlwifi: fix bugs in beacon configuration

When sending beacon commands to the uCode, we must
inform it of the offset in the beacon frame of the
TIM Element so it can transmit packets from the
correct queue. This functionality is implemented
in iwl_set_beacon_tim().

Fix a bug setting the rate_n_flags for the beacon
packet. First, it should not use the station table's
rate (it's a management frame), and second it needs
to properly configure the TX antennas.

Finally, also, clean up and comment relevant functions.

Subject: iwlwifi: handle unicast PS buffering

Using the new mac80211 functionality, this makes
iwlwifi handle unicast PS buffering correctly.
The device works like this:

 * when a station goes to sleep, the microcode notices
   this and marks the station as asleep
 * when the station is marked asleep, the microcode
   refuses to transmit to the station and rejects all
   frames queued to it with the failure status code
   TX_STATUS_FAIL_DEST_PS (a previous patch handled
   this correctly)
 * when we need to send frames to the station _although_
   it is asleep, we need to tell the ucode how many,
   and this is asynchronous with sending so we cannot
   just send the frames, we need to wait for all other
   frames to be flushed, and then update the counter
   before sending out the poll response frames. This
   is handled partially in the driver and partially in
   mac80211.

In order to do all this correctly, we need to
 * keep track of how many frames are pending for each
   associated client station (avoid doing it for other
   stations to avoid the atomic ops)
 * tell mac80211 that we driver-block the PS status
   while there are still frames pending on the queues,
   and once they are all rejected (due to the dest sta
   being in PS) unblock mac80211

Subject: ath9k: get rid of tx_info_priv

This patch removes the need for separately allocated private tx info
data in ath9k and brings the driver one small step closer to using the
mac80211 rate control API properly.

From: Sujith <Sujith.Manoharan@atheros.com>

Subject: ath9k: Cleanup bss_info_changed callback

* Remove a code chunk dealing with operating mode changes.
  As noted, all such policy changes are to be done in
  add_interface.

* Remove pointless check for empty BSSID.
  Also, remove mode checks - mac80211 does all the needed checks.

* Handle enabling/disabling beacon transmission properly.

* Handle beacon interval changes for AP mode.
  The original code depended on config_interface() to update
  the HW TSF. Since that callback has been removed, handle
  it properly.

* Remove unneeded code dealing with key/privacy.

* Set the chainmasks to 1x1 for IBSS when the BSSID is set.
  This was happening uncondionally before.

Subject: ath9k: Remove a few unused functions

ATH9K_ANT_VARIABLE is the default diversity control used.
Consequently ath9k_hw_decrease_chain_power() does nothing.
ath9k_hw_setantennaswitch() is unused too.

Also, gbeacon_rate is unused.

Subject: ath9k: Fix bug in initializing chain masks

Check for AR5416 ver 1.0 before calibrating 3 chains
for multi-chain. This is a WAR for calibration
failure.

Subject: mac80211: convert aggregation to operate on vifs/stas

The entire aggregation code currently operates on the
hw pointer and station addresses, but that needs to
change to make stations purely per-vif; As one step
preparing for that make the aggregation code callable
with the station, or by the combination of virtual
interface and station address.

Subject: ar9170: Add support for D-Link DWA 160 A2

At least two revisions of the D-Link DWA 160 exist, called A1 and A2. A1
(USB-ID 07d1:3c10) is already listed in usb.c as D-Link DWA 160A. A2
(USB-ID 07d1:3a09) works if added to ar9170_usb_ids. I didn't do much
testing until now, but I was able to connect to APs using WPA or WEP and
transmit data.

Summary:

* Add model revision number to the comment for D-Link DWA 160 A1 (07d1:3c10)
* Add support for D-Link DWA 160 A2 (07d1:3a09)

  - It works around a firmware race condition if ELP is entered too fast
    after commands (resulting in ELP timeout -traces)
  - It will reduce the number of sleep-wake cycles between already
    scheduled events such as interrupts and tx, hence improving
    performance (less delay in switching between RX and TX)

Subject: wl1251: allocate space for firmware with vmalloc()

Earlier firmware was stored to a memory area allocated with kmalloc()
but finding a a contiguous area of memory long enough for the firmware is
very difficult in certain cases. better to allocate the memory for firmware
with vmalloc() instead and use a small buffer for DMA transfers.

Thanks to Eero Tamminen for the idea.

This patch increases the number of beacons to be missed before generating
SYNC TIMEOUT event. It increases the beacon timeout period to 500
microseconds, which gives enough time for the firmware to receive probe
response or beacon. Also handled the regain event from firmware once it
receives a probe response or beacon.

Subject: wl1251: Send null data packet with "TODS" bit set

According to IEEE80211 standard all the data packets have to be sent with
TODS bit set. This patch fixes the null data packet format which was sent
without TODS bit set. This should fix many problems associated with
power save. Janne Ylalehto also found this fix in the same time as mine,
for a different bug he was working on.

Subject: b43: Enforce DMA descriptor memory constraints

Enforce all device constraints on the descriptor memory region.

There are several constraints on the descriptor memory, as documented
in the specification. The current code does not enforce them and/or
incorrectly enforces them.

Those constraints are:
- The address limitations on 30/32bit engines, that also apply to
  the skbs.
- The 4k alignment requirement on 30/32bit engines.
- The 8k alignment requirement on 64bit engines.

Subject: mac80211: request TX status where needed

Right now all frames mac80211 hands to the driver
have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set to
request TX status. This isn't really necessary, only
the injected frames need TX status (the latter for
hostapd) so move setting this flag.

The rate control algorithms also need TX status, but
they don't require it.

Also, rt2x00 uses that bit for its own purposes and
seems to require it being set for all frames, but
that can be fixed in rt2x00.

This doesn't really change anything for any drivers
but in the future drivers using hw-rate control may
opt to not report TX status for frames that don't
have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set.

From a3caa99e6c68f466c13cfea74097f6fb01b45e25 Mon Sep 17 00:00:00 2001
From: "John W. Linville" <linville@tuxdriver.com>
Date: Tue, 25 Aug 2009 14:12:25 -0400
Subject: libipw: initiate cfg80211 API conversion (v2)

Initiate the conversion of libipw to the new cfg80211 configuration API.

For now, leave CONFIG_IPW2200_PROMISCUOUS stuff alone.  Eventually
migrate it to cfg80211 when the add/del/change_virtual_intf methods
are implemented.

(v2: Fix unconditional wiphy_unregister in libipw which was causing
     problems for ipw2100, somewhat based on prior attempted fix
     by Zhu Yi <yi.zhu@intel.com>.  Previously both original version of
     this patch and Zhu Yi's fix attempt were reverted due to
     discovery of regressions. -- JWL)

Subject: ipw2100: Register the wiphy device

libipw unconditionally calls wiphy_unregister, but it's up to the driver
to register it in the first place. ipw2100 fails to do so. Add the necessary
glue code, and also ensure that rfkill statuses get set up appropriately.

(Augmented for proper wiphy_unregister placement. -- JWL)

Subject: ipw2200: Set core hw rfkill status when hardware changes state

ipw2200 is able to detect when it's been hard-killed, but doesn't update
the core rfkill state or update userspace. Ensure that the state is updated,
allowing the rfkill core to notify userspace.

Subject: ath9k: This patch fix RX unpadding for any received frame.

It has been tested with a 802.11 frame generator and by checking the FCS field
of each received frame with the value reported by the Atheros hardware. This
patch is useful if you are trying to analyze non standard 802.11 frame going
over the air.

Subject: b43: Rewrite DMA Tx status handling sanity checks

This rewrites the error handling policies in the TX status handler.
It tries to be error-tolerant as in "try hard to not crash the machine".
It won't recover from errors (that are bugs in the firmware or driver),
because that's impossible. However, it will return a more or less useful
error message and bail out. It also tries hard to use rate-limited messages
to not flood the syslog in case of a failure.

Subject: ath5k: Fix I/Q calibration

The sign of correction coefficients was lost in the calculations, which
caused high packetloss in 802.11a mode after the results were applied.
Fixed by removing unneccesary and broken AND with a bit mask.

From: Ben Cahill <ben.m.cahill@intel.com>
Date: Fri, 20 Nov 2009 12:04:53 -0800
Subject: iwlagn: Use iwl_write8() for CSR_INT_COALESCING register

CSR_INT_COALESCING previously had only one, but now has two single-byte fields.
With only one single-byte field (lowest order byte) it was okay to write via
iwl_write32(), but now with two, an iwl_write32() to the lower order field
clobbers the other field (odd-address CSR_INT_PERIODIC_REG, offset 0x5), and an
iwl_write32() to CSR_INT_PERIODIC_REG could clobber the lowest byte of the
next-higher register (CSR_INT, offset 0x8).

Fortunately, no bad side effects have been produced by the iwl_write32()
usage, due to order of execution (low order byte was always written before
higher order byte), and the fact that writing "0" to the low byte of the
next higher register has no effect (only action is when writing "1"s).

Nonetheless, this cleans up the accesses so no bad side effects might occur
in the future, if execution order changes, or more bit fields get added to
CSR_INT_COALESCING.

Add some comments regarding periodic interrupt usage.

Subject: iwlwifi: reset led_tpt when clear tx/rx traffic byte counts

LED blink rate is based on the traffic load, when tx/rx traffic counts
got reset, we also need to reset the led_tpt to prevent incorrect
blink rate being calculated.

Merge both clear_tx_statistics() and clear_rx_statistics() into
single clear_traffic_statistics() function, when reset the traffic byte
counts, both tx and rx need to be reset at the same time, to make
sure calculated the correct led blink rate.

Subject: iwlwifi: separate IO tracing

Since IO tracing is usually not needed and
generates a lot of data, separate it into
its own trace system so that we can always
enable iwlwifi:* and not have to worry about
getting too much data. If IO tracing is then
really needed we can enable iwlwifi_io:* in
addition and get that data.

Subject: iwlwifi: by default, dump entire sram data portion

For "sram" debugfs file, if user did not specify the offset and length,
dump the entire data portion of sram by default.
Data portion is 0x800000 - 0x80ffff, but the actual data size is known
to the driver from the ucode file.

Subject: iwlwifi: dump error log when uCode error occurred

uCode error log contain information as to what the error was and where
it occurred necessary to debug any uCode issues.

Always log the information without special debug flag, this can help to
capture the important information when error happened.

Subject: iwlwifi: Tell the ucode immediately when association state changes

When we get a state change of associated or not, we need to tell the
ucode via the RX_ON command using the filter flags.  This will prevent
the ucode from sending any packets when not associated, specifically not
sending NULL QOS packets after a deauthentication which causes the AP to
repeatedly send deauth's in some situations.

Subject: iwlwifi: print limited number of event log when uCode error

To help iwlagn uCode debugging, event log will dump to syslog when driver
detect uCode error occurred, but this only happen when compile with
CONFIG_IWLWIFI_DEBUG and debug flag is enabled; which is not always
the case. Also, there is another problem, if the flag is set, the entire
event log buffer will be dump to syslog, it can flood the syslog and
make it very difficult to debug the problem.

Change the default to only dump last 20 entries of event log to syslog
unless the following condition meets:
1. both compile with CONFIG_IWLWIFI_DEBUG and debug flag
is enabled, and then dump the entire event buffer to syslog.
2. dump event log request from debugfs

Subject: iwlwifi: remove reset led_tpt from iwl_leds_init()

Current blinking rate is calculated based on the difference between
current tx/rx byte counts and priv->led_tpt.

priv->led_tpt should not get reset in iwl_leds_init(), this function can be
called by bring interface "up" or "down", or when uCode sysassert occurred.
resetting the led_tpt parameter will introduce incorrect led blinking behavior.

Subject: rndis_wlan: fix buffer overflow in rndis_query_oid

rndis_query_oid overwrites *len which stores buffer size to return full size
of received command and then uses *len with memcpy to fill buffer with
command.

Ofcourse memcpy should be done before replacing buffer size.

Subject: rndis_wlan: disable stall workaround

Stall workaround doesn't work with bcm4320a devices like with bcm4320b.
This workaround actually causes more stalls/device freeze on bcm4320a.
Therefore disable stall workaround by default.
