Subject: [PATCH] mac80211: add an intermediate software queue implementation
This allows drivers to request per-vif and per-sta-tid queues from which
they can pull frames. This makes it easier to keep the hardware queues
short, and to improve fairness between clients and vifs.
The task of scheduling packet transmission is left up to the driver -
queueing is controlled by mac80211. Drivers can only dequeue packets by
calling ieee80211_tx_dequeue. This makes it possible to add active queue
management later without changing drivers using this code.
This can also be used as a starting point to implement A-MSDU
aggregation in a way that does not add artificially induced latency.

+/**
+ * DOC: mac80211 software tx queueing
+ *
+ * mac80211 provides an optional intermediate queueing implementation designed
+ * to allow the driver to keep hardware queues short and provide some fairness
+ * between different stations/interfaces.
+ * In this model, the driver pulls data frames from the mac80211 queue instead
+ * of letting mac80211 push them via drv_tx().
+ * Other frames (e.g. control or management) are still pushed using drv_tx().
+ *
+ * Drivers indicate that they use this model by implementing the .wake_tx_queue
+ * driver operation.
+ *
+ * Intermediate queues (struct ieee80211_txq) are kept per-sta per-tid, with a
+ * single per-vif queue for multicast data frames.
+ *
+ * The driver is expected to initialize its private per-queue data for stations
+ * and interfaces in the .add_interface and .sta_add ops.
+ *
+ * The driver can't access the queue directly. To dequeue a frame, it calls
+ * ieee80211_tx_dequeue(). Whenever mac80211 adds a new frame to a queue, it
+ * calls the .wake_tx_queue driver op.
+ *
+ * For AP powersave TIM handling, the driver only needs to indicate if it has
+ * buffered packets in the driver specific data structures by calling
+ * ieee80211_sta_set_buffered(). For frames buffered in the ieee80211_txq
+ * struct, mac80211 sets the appropriate TIM PVB bits and calls
+ * .release_buffered_frames().
+ * In that callback the driver is therefore expected to release its own
+ * buffered frames and afterwards also frames from the ieee80211_txq (obtained
+ * via the usual ieee80211_tx_dequeue).

Subject: [PATCH] mac80211: lock rate control
Both minstrel (reported by Sven Eckelmann) and the iwlwifi rate
control aren't properly taking concurrency into account. It's
likely that the same is true for other rate control algorithms.
In the case of minstrel this manifests itself in crashes when an
update and other data access are run concurrently, for example
when the stations change bandwidth or similar. In iwlwifi, this
can cause firmware crashes.
Since fixing all rate control algorithms will be very difficult,
just provide locking for invocations. This protects the internal
data structures the algorithms maintain.
I've manipulated hostapd to test this, by having it change its
advertised bandwidth roughly ever 150ms. At the same time, I'm
running a flood ping between the client and the AP, which causes
this race of update vs. get_rate/status to easily happen on the
client. With this change, the system survives this test.

Subject: [PATCH] ath: DFS - limit number of potential PRI sequences
In the PRI detector, after the current radar pulse
has been checked agains existing PRI sequences, it
is considered as part of a new potential sequence.
Previously, the condition to accept a new sequence
was to have at least the same number of pulses as
the longest matching sequence. This was wrong,
since it led to duplicates of PRI sequences.
This patch changes the acceptance criteria for new
potential sequences from 'at least' to 'more than'
the longest existing.
Detection performance remains unaffected, while
the number of PRI sequences accounted at runtime
(and with it CPU load) is reduced by up to 50%.

Subject: [PATCH] ath9k: add DFS support for extension channel
In HT40 modes, pulse events on primary and extension
channel are processed individually. If valid, a pulse
event will be fed into the detector
* for primary frequency, or
* for extension frequency (+/-20MHz based on HT40-mode)
* or both
With that, a 40MHz radar will result in two individual
radar events.

Subject: [PATCH] ath9k: DFS - add pulse chirp detection for FCC
FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.
A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range
The chirp detection has been tested with reference
radar generating devices and proved to work reliably.

Subject: [PATCH] ath5k: channel change fix
ath5k updates the channel pointer and after that it stops the Rx logic
and apply channel to HW. In case of channel switch, such sequence
creates a small window when a frame, which is received on the old
channel is considered as a frame received on the new one.
The most notable consequence of this situation occurs during the switch
from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received
with CCK rate, e.g. beacon received at the 1mbps, causes the following
warning:

The easiest way to reproduce this warning is to run scan with dualband
NIC in noisy environments, when the channel 11 runs multiple APs. In my
tests if the APs num >= 12, the warning appears in the first few
seconds of scanning.
In order to fix this, the Rx disable code moved to a higher level and
placed before the channel pointer update. This is also makes the code a
bit more symmetrical, since we disable and enable the Rx in the same
function.
In fact, at the pointer update time new frames should not appear,
because interrupt generation at this point should already be disabled.
The next patch should address this issue.

Subject: [PATCH] ath5k: fix reset race
To prepare for reset ath5k should finish all asynchronous tasks. At
first, it disables the interrupt generation, then it waits for the
interrupt handler and tasklets completion, and then proceeds to the HW
configuration update. But it does not consider that the interrupt
handler or tasklet re-enables the interrupt generation. And we fall in a
situation when ath5k assumes that interrupts are disabled, but it is
not.
This can lead to different consequences, such as reception of the frame,
when we do not expect it. Under certain circumstances, this can lead to
the following warning:
WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]()

Fix this issue by adding a new status flag, which forbids to re-enable
the interrupt generation until the HW configuration is completed.
Note: previous patch, which reorders the Rx disable code helps to avoid
the above warning, but not fixes the root cause of unexpected frame
receiving.

Subject: [PATCH] ath9k: limit retries for powersave response frames
In some cases, the channel might be busy enough that an ath9k AP's
response to PS-Poll frames might be too slow and the station has already
gone to sleep. To avoid wasting too much airtime on this, limit the
number of retries on such frames and ensure that no sample rate gets
used.

Subject: [PATCH] ath10k: Delay device access after cold reset
It is observed that during cold reset pcie access right
after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
Data Bus Error and system hard lockup. The reason
for bus error is that pcie needs some time to get
back to stable state for any transaction during cold reset. Add
delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
to fix this issue.

Subject: [PATCH] ath9k: fix tracking of enabled AP beacons
sc->nbcnvifs tracks assigned beacon slots, not enabled beacons.
Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool)
should be updated, or if beacons have been enabled already.
With the current code (depending on the order of calls), beacons often
do not get enabled in an AP+STA setup.
To fix tracking of enabled beacons, convert cur_conf->enable_beacon to a
bitmask of enabled beacon slots.

Subject: [PATCH] mac80211: minstrel_ht: fix rounding issue in MCS duration
calculation
On very high MCS bitrates, the calculated duration of rates that are
next to each other can be very imprecise, due to the small packet size
used as reference (1200 bytes).
This is most visible in VHT80 nss=2 MCS8/9, for which minstrel shows the
same throughput when the probability is also the same. This leads to a
bad rate selection for such rates.
Fix this issue by introducing an average A-MPDU size factor into the
calculation.

Subject: [PATCH] mac80211: don't look up destination station twice
There's no need to look up the destination station twice while
building the 802.11 header for a given frame if the frame will
actually be transmitted to the station we initially looked up.
This happens for 4-addr VLAN interfaces and TDLS connections, which
both directly send the frame to the station they looked up, though
in the case of TDLS some station conditions need to be checked.
To avoid that, add a variable indicating that we've looked up the
station that the frame is going to be transmitted to, and avoid the
lookup/flag checking if it already has been done.
In the TDLS case, also move the authorized/wme_sta flag assignment
to the correct place, i.e. only when that station is really used.
Before this change, the new lookup should always have succeeded so
that the potentially erroneous data would be overwritten.

If there's no station on the 4-addr VLAN interface, then frames
cannot be transmitted. Drop such frames earlier, before setting
up all the information for them.
We should keep the old check though since that code might be used
for other internally-generated frames.

Subject: [PATCH] mac80211: avoid duplicate TX path station lookup
Instead of looking up the destination station twice in the TX path
(first to build the header, and then for control processing), save
it when building the header and use it later in the TX path.
To avoid having to look up the station in the many callers, allow
those to pass %NULL which keeps the existing lookup.

response arrives before wait_event_timeout is called, this
will result in situation that wait_event_timeout never gets
woken again and assumed result will be a timeout. This patch
removes that errornous situation by always setting the
ctl_completed var before checking for queue active.

Subject: [PATCH] ath9k_htc: add new WMI_REG_RMW_CMDID command
Since usb bus add extra delay on each request, a command
with read + write requests is too expensive. We can dramtically
reduce usb load by moving this command to firmware.
In my tests, this patch will reduce channel scan time
for about 5-10 seconds.

Subject: [PATCH] ath9k: use REG_RMW and rmw buffer in
ath9k_hw_4k_set_gain
it is possible to reduce time needed for this function
by rplacing REG_WRITE with REG_RMW (plus dummy 0) and putt all commands
in same buffer.

Subject: [PATCH] brcmfmac: Fix oops when SDIO device is removed.
On removal of SDIO card both functions of card will be getting
a remove call. When the first is hanging in ctrl frame xmit then
the second will cause oops. This patch fixes the xmit ctrl
handling in case of serious errors and also limits the handling
for remove to function 1 only.

Subject: [PATCH] brcmfmac: Fix possible race-condition.
SDIO is using a "shared" variable to handoff ctl frames to DPC
and to see when they are done. In a timeout situation this can
lead to erroneous situation where DPC started to handle the ctl
frame while the timeout expired. This patch will fix this by
adding locking around the shared variable.

Subject: [PATCH] brcmfmac: take save&restore memory into account for SDIO
shared info
The firmware provides pointer to SDIO shared information at end of
RAM during firmware initialization. End of RAM is obviously determined
by the actual ram size, but part of that may be used for save&restore
memory. In that case another location in RAM will hold the pointer.

Subject: [PATCH] brcmfmac: fix watchdog timer regression
The watchdog timer is used to put the device in a low-power mode when
it is idle for some time. This timer is stopped during that mode and
should be restarted upon activity. This has been broken by commit
d4150fced0365 ("brcmfmac: Simplify watchdog sleep."). This patch
restores the behaviour as it was before that commit.

Subject: [PATCH] brcmfmac: avoid runtime-pm for sdio host controller
Several host controllers supporting runtime-pm are causing issues
with our sdio wireless cards because they disable the sdio interrupt
upon going into runtime suspend. This patch avoids that by doing
a pm_runtime_forbid() call during the probe. Tested with Sony Vaio
Duo 13 which uses sdhci-acpi host controller.

Recently support was added for the BCM4345 SDIO chipset by
commit 9c51026509d7 ("brcmfmac: Add support for BCM4345 SDIO chipset")
however this was verified using a BCM43455 device, which is
a more recent revision of the chip. This patch assure that
older revisions are not probed as they would fail.

Subject: [PATCH] brcmfmac: use static superset of channels for wiphy
bands
The driver was constructing a list of channels per wiphy band
by querying the device. This list is not what the hardware is
able to do as it is already filtered by the country setting in
the device. As user-space may change the country this would
require updating the channel list which is not recommended [1].
This patch introduces a superset of channels. The individual
channels are disabled appropriately by querying the device.

Subject: [PATCH] brcmfmac: fix sdio suspend and resume
commit 330b4e4be937 ("brcmfmac: Add wowl support for SDIO devices.")
changed the behaviour by removing the MMC_PM_KEEP_POWER flag for
non-wowl scenario, which needs to be restored. Another necessary
change is to mark the card as being non-removable. With this in place
the suspend resume test passes successfully doing:
# echo devices > /sys/power/pm_test
# echo mem > /sys/power/state
Note that power may still be switched off when system is going
in S3 state.

Subject: [PATCH] brcmfmac: Add support for multiple PCIE devices in
nvram.
With PCIE it is possible to support multiple devices with the
same device type. They all load the same nvram file. In order to
support this the nvram can specify which part of the nvram is
for which pcie device. This patch adds support for these new
types of nvram files.

Subject: [PATCH] brcmfmac: cleanup a sizeof()
"flowrings" and "*flowrings" are both pointers so this always returns
sizeof(void *) and the current code works fine. But "*flowrings" is
intended here and static checkers complain, so lets change it.

Subject: [PATCH] brcmfmac: prohibit ACPI power management for brcmfmac driver
ACPI will manage WiFi chip's power state during suspend/resume
process on some tablet platforms(such as ASUS T100TA). This is
not supported by brcmfmac driver now, and the context of WiFi
chip will be damaged after resume. This patch informs ACPI not
to manage WiFi chip's power state.

Subject: [PATCH] brcmfmac: avoid gcc-5.1 warning
gcc-5.0 gained a new warning in the fwsignal portion of the brcmfmac
driver:
drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c: In function 'brcmf_fws_txs_process':
drivers/net/wireless/brcm80211/brcmfmac/fwsignal.c:1478:8: warning: 'skb' may be used uninitialized in this function [-Wmaybe-uninitialized]
This is a false positive, and marking the brcmf_fws_hanger_poppkt function
as 'static inline' makes the warning go away. I have checked the object
file output and while a little code gets moved around, the size of
the binary remains identical.

Subject: [PATCH] brcmfmac: allow device tree node without 'interrupts'
property
As described in the device tree bindings for 'brcm,bcm4329-fmac'
nodes, the interrupts property is optional. So adding a check
for the presence of this property before attempting to parse
and map the interrupt. If not present or parsing fails return
and fallback to in-band sdio interrupt.

Subject: [PATCH] brcmfmac: Improve throughput by scheduling msbug flow worker.
The tx flow worker in msgbuf gets scheduled at tx till a certain
threshold has been reached. Then the tx completes will take over
the scheduling. When amsdu and ampdu is used the frames are
transferred wireless in a very bulky fashion, in combination
with this scheduling algorithm and buffer limiters in the stack
this can result in limited throughput. This change causes the
flow worker to be scheduled more frequently from tx.

brcmf_msgbuf_get_pktid() fails
The function brcmf_msgbuf_get_pktid() may return a NULL pointer so
the callers should check the return pointer before accessing it to
avoid the crash below (see [1]):

Comparing NVRAM entry with a full filtering string is simpler than
comparing it with a short prefix and then checking random chars at magic

Tested on BCM43602 with NVRAM hacked to use V2 format.

Subject: [PATCH] brcmfmac: treat \0 as end of comment when parsing NVRAM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This fixes brcmfmac dealing with NVRAM coming from platform e.g. from a
flash MTD partition. In such cases entries are separated by \0 instead
of \n which caused ignoring whole content after the first "comment".
While platform NVRAM doesn't usually contain comments, we switch to
COMMENT state after e.g. finding an unexpected char in key name.
