Subject: b43: Update dummy transmission to match V4 specs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The V4 dummy transmission has two extra bools in its prototype,
so update all callers with the 2 bools.

Subject: iwlwifi: prevent read outside array bounds

With EDCA and HCCA we have 16 potential tid values. This is accommodated by
mac80211, but iwlwifi only supports EDCA. With this implementation it is
thus possible for mac80211 to request a tid that will cause iwlwifi to read
outside array bounds. A similar problem exists if traffic is received in an
unsupported category.

We add error checking to catch these situations.

Subject: iwlwifi: include HT configuration when adding stations through
 rs_rate_init

Driver's first notification of a new station from mac80211 can be through rate
selection API.  This patch fixes a bug where, in this code path, the HT
capabilities of the new station were ignored.

Subject: iwlwifi: traverse linklist to find the valid OTP block

For devices using OTP memory, EEPROM image can start from
any one of the OTP blocks. If shadow RAM is disabled, we need to
traverse link list to find the last valid block, then start the EEPROM
image reading.

If OTP is not full, the valid block is the block _before_ the last block
on the link list; the last block on the link list is the empty block
ready for next OTP refresh/update.

If OTP is full, then the last block is the valid block to be used for
configure the device.

Subject: iwlwifi: remove unused members of iwl_ht_info

Some members of iwl_ht_info are unused, and one of
them is write-only, so we can remove these three:
max_amsdu_size, ampdu_factor and mpdu_density.

Subject: iwlwifi: refactor packet reception code

This patch fixes a number of issues in iwl_rx_reply_rx and
iwl_pass_packet_to_mac80211.  These issues stem from the complexities of
managing two different types of packet commands for different hardware.

- Unify code handling rx_phy_res in SKB or cached to eliminate redundancy and
remove potential NULL pointer accesses
- Replace magic number with proper constant
- Optimize functions by moving early exit conditions before computation
- Comment code and improve some variable names
- Remove redundant computation in iwl_pass_packet_to_mac80211 by passing in the
correct, already-computed arguments.

Subject: iwlwifi: configure HT40 channels in iwl_mac_config

As indicated by note in iwl_ht_conf, some HT parameters are set on association
(e.g., channel width) and some vary over time (HT protection mode) and per
station (e.g., short GI support).  The global parameters should be set in
iwl_mac_config and the local/varying parameters in iwl_ht_conf.

This patch moves the channel width configuration from iwl_ht_conf to
iwl_mac_config, and defers further cleanup of the local/global conflation for a
later patch.

This fixes a bug in using HT40 channels in some modes.

Subject: iwlwifi: check short GI support per-station rather than globally

Short guard interval support is a local per-station parameter not a global
per-NIC parameter.  (mac80211 will correctly remove SGI support from station
capabilities if the BSS does not permit it).  This patch removes the short GI
support bitfield from the global iwl_ht_info struct and properly uses
per-station HT capabilities during rate selection.

Subject: iwlwifi: use station HT capabilities and BSS operating mode for
 Green-field

Green-field mode should be configured in the HT station table.  This patch uses
both the per-station GF support flag as well as the current BSS HT operation
mode (non-GF stations present flag).

Added the "ht_greenfield_support" field to struct iwl_cfg to replace the
device-specific check in rs_use_green().  That check has been moved to
iwlcore_init_ht_hw_capab().

Subject: iwlwifi: fix erroneous use of iwl_rx_packet.len as a length

The field called 'len' in struct iwl_rx_packet is in fact not just a length
field but also includes some flags from the flow handler.  In several places
throughout the driver, this causes incorrect values to be interpreted as
lengths when the field is improperly masked.

In most situations the improper use is for debugging output, and simply results
in an erroneous message, such as:

[551933.070224] ieee80211 phy0: I iwl_rx_statistics Statistics notification received (480 vs -1367342620).

which should read '(480 vs 484)'.

In at least one case this could case bad things to happen:

void iwl_rx_pm_debug_statistics_notif(struct iwl_priv *priv,
                                      struct iwl_rx_mem_buffer *rxb)
{
        struct iwl_rx_packet *pkt = (struct iwl_rx_packet *)rxb->skb->data;
        IWL_DEBUG_RADIO(priv, "Dumping %d bytes of unhandled "
                        "notification for %s:\n",
                        le32_to_cpu(pkt->len), get_cmd_string(pkt->hdr.cmd));
        iwl_print_hex_dump(priv, IWL_DL_RADIO, pkt->u.raw, le32_to_cpu(pkt->len)
);
}
EXPORT_SYMBOL(iwl_rx_pm_debug_statistics_notif);

Given the rampant misuse of this field without proper masking throughout the
driver (every use but one), this patch renames the field from 'len' to
'len_n_flags' to reduce confusion.  It also adds the proper masking when
this field is used as a length value.

Subject: b43: LP-PHY: Implement channel switching for rev0/1/B2062 radio
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

-Move pdiv from lpphy_2062_init to struct b43_phy_lp.
-Add channel table for the B2062 radio.
-Add code for tuning the B2062 radio to channel.
-Add error handling to op_switch_channel, and use it for both radios.

Rev0/1/B2062 will now hopefully show some signs of life, though
it won't work at full performance, as calibration is still missing.

Subject: p54: disable PS by default

Johannes kindly pointed out that I completely missed a hunk in
his patch: "[PATCH] cfg80211: allow driver to override PS default".

The driver must explicitly set ps_default to false,
as the setting is pre-filled with the kconfig default.

The spec had some nasty typos, and a large part of the rev0/1 BB
init procedure was also missing. Fix these.

Also make the init-time channel switch debuggable.

(The change from -EINVAL to -EIO is simply to make it possible
to distinguish the PLL charge pump error from a channel-not-found
error.)

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A few typos have been discovered in both the specs and the code.
This patch fixes them.

Also use lpphy_op_switch_channel consistently, and make all users
of it print its return value for easier debugging.

Subject: b43: LP-PHY: Remove BROKEN from B43_PHY_LP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Larry has reported success getting scan data with an LP-PHY device,
so it's probably time to release LP-PHY support for testing.

Also disable 802.11a support for now, as 802.11a currently causes
the driver to panic on startup (NULL pointer dereference).

Subject: mac80211: allow configure_filter callback to sleep

Over time, a whole bunch of drivers have come up
with their own scheme to delay the configure_filter
operation to a workqueue. To be able to simplify
things, allow configure_filter to sleep, and add
a new prepare_multicast callback that drivers that
need the multicast address list implement. This new
callback must be atomic, but most drivers either
don't care or just calculate a hash which can be
done atomically and then uploaded to the hardware
non-atomically.

A cursory look suggests that at76c50x-usb, ar9170,
mwl8k (which is actually very broken now), rt2x00,
wl1251, wl1271 and zd1211 should make use of this
new capability.

Subject: mac80211: remove deprecated API

All but two drivers have now stopped using the two
deprecated members radio_enabled and beacon_int,
so it's about time to remove them for good.

Subject: wl1251: correct definitions for 0th bit defines

ACX_SLV_SOFT_RESET_BIT and ACX_REG_EEPROM_START_BIT are both defined
as "1" in the vendor driver code, but they were defined to be BIT(1)
("2") here.

The SOFT_RESET typo ensures that wl1251_boot_soft_reset() doesn't;
as a result the device hangs when trying to reprogram the PLL
registers while running.

Subject: rt2x00: Fix RFKILL polling

The rfkill_poll callback function in the drivers check a bit
to see if the RFKILL key has been pressed. However when the
bit is set it means the radio is active and the device can be
used.

The wiphy_rfkill_set_hw_state() function expects the inversed,
so '1' must be send when the radio must be disabled.

Subject: wl1251: halt the embedded CPU before loading firmware

After initial power-up, the embedded cpu is usually halted.  However,
if we down the interface and only do a soft reset before bringing
the interface back up, it will still be running and the firmware
loading code will bail out.  This change halts the CPU before loading
the firmware, enabling a second call to wl1251_boot() to succeed
without a hard reset.

Subject: ath9k: Fix TX poll cancelling

In ath9k_stop(), tx_complete_work was being cancelled twice.
This patch fixes it. Also, locking sc->mutex should be done
at the beginning.

From afa620429ac6a636246f85d97cf205d6533e7fcb Mon Sep 17 00:00:00 2001
From: Ivo van Doorn <ivdoorn@gmail.com>
Date: Tue, 18 Aug 2009 19:54:23 +0200
Subject: rt2x00: configure_filter() callback is allowed to sleep

The configure_filter() callback function no longer needs
to be atomic. Remove the scheduled work structure and
call into the driver configure_filter() directly.

Subject: rt2x00: bss_info_changed() callback is allowed to sleep

The bss_info_changed() callback function no longer needs
to be atomic. Remove the scheduled work structure and
call into the driver directly.

Additionaly this makes the DRIVER_REQUIRE_SCHEDULED
flag redundant so it can be removed.

Subject: b43: LP-PHY: Two small spec updates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The specs are beginning to support rev3 LP-PHYs - implement one of
the changes needed for rev3 support.
Also, in the new MIPS driver, the "Japan TX filter" was renamed to
"analog TX filter init" - however, calling it "init" is confusing,
so name it "set analog filter", with a comment for easier future
identification.

Subject: b43: LP-PHY: Implement spec updates and remove resolved FIXMEs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Larry has started re-checking all current routines against a new
version of the Broadcom MIPS driver. This patch implements the first
round of changes he documented on the specs wiki.

Also remove a few FIXMEs regarding missing initial values for variables
with dynamic initial values where reading the values has been implemented.

Subject: ath9k: Fix bug in retrieving average beacon rssi

Currently the beacon rssi that LPF gives is divided and rounded
up by ATH_RSSI_EP_MULTIPLIER twice. This will leave the incorrect rssi
in ANI. Having correct rssi in ANI fixes the connection stability at
< 30dB rssi range. This patch removes the unncessary computation of average
rssi over already valid average rssi. Also removes the redundant macros to
find average rssi.

Other than ns_avgbrssi (Average beacon rssi) no data of
ath9k_node_stats is being used anywhere. Nuke this structure
and move its only useful member to ar5416Anistate. Also cleanup
this redundant data in ath_softc.

Subject: mwl8k: remove MWL8K_RADIO_* defines

Instead of passing a flag bitmask to mwl8k_cmd_802_11_radio_control,
pass the 'enable' and 'force' arguments as separate parameters, and
introduce wrappers for the common cases of enabling and disabling
without forcing.

Subject: mwl8k: fix mwl8k_configure_filter() parameter lifetime issue

mwl8k_configure_filter() passes pointers to total_flags and the
multicast address list to a workqueue function, while there is no
guarantee that those pointers will still be valid by the time the
workqueue function runs.

Solve this by passing total_flags by value, and by passing an
already built multicast address setup command packet to the workqueue
function so that we don't have to look at the multicast address list
itself outside of mwl8k_configure_filter().

Also, since ->configure_filter() can sleep now, wait synchronously
for the worker to finish.

Subject: mwl8k: ->add_interface() is not called for monitor interfaces

There is no need to check for NL80211_IFTYPE_MONITOR in
->add_interface(), as this function is never called for monitor
interfaces.  Also, there is no need to advertise this bit in our
wiphy's ->interface_modes.

Subject: mwl8k: dma header manipulations can't fail

Adding and removing the DMA header that the mwl8k hardware requires
on tx and provides on rx can never fail, since we are guaranteed to
have enough headroom on the tx path to expand the packet, and we only
ever shrink the packet on the rx path.  (And on both paths we are
guaranteed to be the only user of the skb we are handling.)

This allows removing all of the skb clone handling in the tx and tx
reclaim paths, and eliminates error checks in both the tx and rx
paths, simplifying the code a bit more.

Subject: mwl8k: don't touch 'command done' interrupt during firmware load

Since firmware load commands don't generate 'command done' interrupts
like normal commands do, polling for command done interrupts just
unnecessarily slows down the firmware load process.  Removing this bit
of code speeds up loading a typical firmware image from 840 msec to
180 msec.

Subject: mwl8k: mwl8k_txq_xmit() rework

Various mwl8k_txq_xmit changes:
- Extract the QoS field before adding the DMA header.
- Only write to tx->status once, and only after all the other
  descriptor fields have been set.
- Do all tx state manipulation under the tx spinlock.
- Remove the priv->inconfig check, as all transmit queues will
  be frozen during config cycles, so we won't ever be asked to
  transmit if a config cycle is running.
- Remove some more dead code.

Subject: mwl8k: mwl8k_queue_work() cleanup

Delete most of the mwl8k_work_struct fields and options, since most
of them are unused or never changed from their defaults:
- We always use priv->config_wq, so delete the wqueue argument from
  mwl8k_queue_work().
- MWL8K_WQ_SPIN and MWL8K_WQ_POST_REQUEST are never used, as all
  callers sleep for request completion, so sleep unconditionally.
- MWL8K_WQ_FREE_WORKSTRUCT is never used.
- MWL8K_WQ_TX_WAIT_EMPTY is always set, so assume it unconditionally.
- timeout_ms/txwait_attempts/tx_timeout_ms are never changed from
  their defaults, so just hardcode these in the workqueue worker.
- step is never used.

Subject: mwl8k: fix firmware command serialisation

The current mwl8k_priv->fw_lock spinlock doesn't actually protect
against multiple commands being submitted at once, as it is not kept
held over the entire firmware command submission.  And since waiting
for command completion sleeps, we can't use a spinlock anyway.

To fix mwl8k firmware command serialisation properly, we have the
following requirements:
- Some commands require that the packet transmit path is idle when
  the command is issued.  (For simplicity, we'll just quiesce the
  transmit path for every command.)
- There are certain sequences of commands that need to be issued to
  the hardware sequentially, with no other intervening commands.

This leads to an implementation of a "firmware lock" as a mutex that
can be taken recursively, and which is taken by both the low-level
command submission function (mwl8k_post_cmd) as well as any users of
that function that require issuing of an atomic sequence of commands,
and quiesces the transmit path whenever it's taken.
