From: =?UTF-8?q?Toke=20H=C3=B8iland-J=C3=B8rgensen?= <toke@toke.dk>
Date: Fri, 2 Sep 2016 16:00:30 +0200
Subject: [PATCH] ath9k: Switch to using mac80211 intermediate software
queues.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This switches ath9k over to using the mac80211 intermediate software
queueing mechanism for data packets. It removes the queueing inside the
driver, except for the retry queue, and instead pulls from mac80211 when
a packet is needed. The retry queue is used to store a packet that was
pulled but can't be sent immediately.
The old code path in ath_tx_start that would queue packets has been
removed completely, as has the qlen limit tunables (since there's no
longer a queue in the driver to limit).
Based on Tim's original patch set, but reworked quite thoroughly.

Subject: [PATCH] mac80211: Use rhltable instead of rhashtable
mac80211 currently uses rhashtable with insecure_elasticity set
to true. The latter is because of duplicate objects. What's
more, mac80211 walks the rhashtable chains by hand which is broken
as rhashtable may contain multiple tables due to resizing or
rehashing.
This patch fixes it by converting it to the newly added rhltable
interface which is designed for use with duplicate objects.
With rhltable a lookup returns a list of objects instead of a
single one. This is then fed into the existing for_each_sta_info
macro.
This patch also deletes the sta_addr_hash function since rhashtable
defaults to jhash.

Subject: [PATCH] mac80211: fix sequence number allocation regression
The recent commit that moved around TX handlers dropped the sequence
number allocation at the end of ieee80211_tx_dequeue and calls
ieee80211_tx_h_sequence instead (for the non-fast-xmit case).
However, it did not change the fast-xmit sequence allocation condition
in ieee80211_xmit_fast_finish, which skipped seqno alloc if intermediate
tx queues are being used.
Drop the now obsolete condition.
Fixes: bb42f2d13ffc ("mac80211: Move reorder-sensitive TX handlers to after TXQ dequeue")

Subject: [PATCH] rt2x00: avoid introducing a USB dependency in the
rt2x00lib module
As reported by Felix:
Though protected by an ifdef, introducing an usb symbol dependency in
the rt2x00lib module is a major inconvenience for distributions that
package kernel modules split into individual packages.
Get rid of this unnecessary dependency by calling the usb related
function from a more suitable place.

This reverts commit c68df2e7be0c1238ea3c281fd744a204ef3b15a0.
__sta_info_recalc_tim turns into a no-op if local->ops->set_tim is not
set. This prevents the beacon TIM bit from being set for all drivers
that do not implement this op (almost all of them), thus thoroughly
essential AP mode powersave functionality.

Commit b2d70d4944c1 ("ath9k: make GPIO API to support both of WMAC and
SOC") refactored ath9k_hw_gpio_get() to support both WMAC and SOC GPIOs,
changing the return on success from 1 to BIT(gpio). This broke some callers
like ath_is_rfkill_set().
Instead of fixing all callers, change ath9k_hw_gpio_get() back to only
return 0 or 1.

+* Qualcomm Atheros ath9k wireless devices
+
+This node provides properties for configuring the ath9k wireless device. The
+node is expected to be specified as a child node of the PCI controller to
+which the wireless chip is connected.
+
+Required properties:
+- compatible: For PCI and PCIe devices this should be an identifier following
+ the format as defined in "PCI Bus Binding to Open Firmware"
+ Revision 2.1. One of the possible formats is "pciVVVV,DDDD"
+ where VVVV is the PCI vendor ID and DDDD is PCI device ID.
+ Typically QCA's PCI vendor ID 168c is used while the PCI device
+ ID depends on the chipset - see the following (possibly
+ incomplete) list:
+ - 0023 for AR5416
+ - 0024 for AR5418
+ - 0027 for AR9160
+ - 0029 for AR9220 and AR9223
+ - 002a for AR9280 and AR9283
+ - 002b for AR9285
+ - 002c for AR2427
+ - 002d for AR9227
+ - 002e for AR9287
+ - 0030 for AR9380, AR9381 and AR9382
+ - 0032 for AR9485
+ - 0033 for AR9580 and AR9590
+ - 0034 for AR9462
+ - 0036 for AR9565
+ - 0037 for AR9485
+- reg: Address and length of the register set for the device.
+
+Optional properties:
+- qca,no-eeprom: Indicates that there is no physical EEPROM connected to the
+ ath9k wireless chip (in this case the calibration /
+ EEPROM data will be loaded from userspace using the
+ kernel firmware loader).
+- mac-address: See ethernet.txt in the parent directory
+- local-mac-address: See ethernet.txt in the parent directory
+
+
+In this example, the node is defined as child node of the PCI controller:
+&pci0 {
+ wifi@168c,002d {
+ compatible = "pci168c,002d";
+ reg = <0x7000 0 0 0 0x1000>;
+ qca,no-eeprom;
+ };
+};

Subject: [PATCH 3/3] ath9k: parse the device configuration from an OF node
This allows setting the MAC address and specifying that the firmware
will be requested from userspace (because there might not be a hardware
EEPROM connected to the chip) for ath9k based PCI devices using
the device tree.
There is some out-of-tree code to "convert devicetree to
ath9k_platform_data" (for example in OpenWrt and LEDE) which becomes
obsolete with this patch.

Starting with ath9k: use ieee80211_tx_status_noskb where possible
[d94a461d7a7df68991fb9663531173f60ef89c68] the driver uses rcu_read_lock() &&
rcu_read_unlock() yet on returning early in ath_tx_edma_tasklet() the unlock is
missing leading to stalls and suspicious RCU usage:

These memory chunks are often used as 'swap' by the NIC,
so it will be both reading and writing to these areas.

Subject: [PATCH] ath10k: Fix soft lockup during firmware crash/hw-restart
During firmware crash (or) user requested manual restart
the system gets into a soft lock up state because of the
below root cause.
During user requested hardware restart / firmware crash
the system goes into a soft lockup state as 'napi_synchronize'
is called after 'napi_disable' (which sets 'NAPI_STATE_SCHED'
bit) and it sleeps into infinite loop as it waits for
'NAPI_STATE_SCHED' to be cleared. This condition is hit because
'ath10k_hif_stop' is called twice as below (resulting in calling
'napi_synchronize' after 'napi_disable')
'ath10k_core_restart' -> 'ath10k_hif_stop' (ATH10K_STATE_ON) ->
-> 'ieee80211_restart_hw' -> 'ath10k_start' -> 'ath10k_halt' ->
'ath10k_core_stop' -> 'ath10k_hif_stop' (ATH10K_STATE_RESTARTING)
Fix this by calling 'ath10k_halt' in ath10k_core_restart itself
as it makes more sense before informing mac80211 to restart h/w
Also remove 'ath10k_halt' in ath10k_start for the state of 'restarting'

Subject: [PATCH] mac80211: minstrel: store probability variance instead of
standard deviation
This avoids the costly int_sqrt calls in the statistics update and moves
it to the debugfs code instead.
This also fixes an overflow in the previous standard deviation
calculation.

Subject: [PATCH] cfg80211: limit scan results cache size
It's possible to make scanning consume almost arbitrary amounts
of memory, e.g. by sending beacon frames with random BSSIDs at
high rates while somebody is scanning.
Limit the number of BSS table entries we're willing to cache to
1000, limiting maximum memory usage to maybe 4-5MB, but lower
in practice - that would be the case for having both full-sized
beacon and probe response frames for each entry; this seems not
possible in practice, so a limit of 1000 entries will likely be
closer to 0.5 MB.

Subject: [PATCH] ath9k: Introduce airtime fairness scheduling between stations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This reworks the ath9k driver to schedule transmissions to connected
stations in a way that enforces airtime fairness between them. It
accomplishes this by measuring the time spent transmitting to or
receiving from a station at TX and RX completion, and accounting this to
a per-station, per-QoS level airtime deficit. Then, an FQ-CoDel based
deficit scheduler is employed at packet dequeue time, to control which
station gets the next transmission opportunity.
Airtime fairness can significantly improve the efficiency of the network
when station rates vary. The following throughput values are from a
simple three-station test scenario, where two stations operate at the
highest HT20 rate, and one station at the lowest, and the scheduler is
employed at the access point:
Before / After
Fast station 1: 19.17 / 25.09 Mbps
Fast station 2: 19.83 / 25.21 Mbps
Slow station: 2.58 / 1.77 Mbps
Total: 41.58 / 52.07 Mbps
The benefit of airtime fairness goes up the more stations are present.
In a 30-station test with one station artificially limited to 1 Mbps,
we have seen aggregate throughput go from 2.14 to 17.76 Mbps.

Subject: [PATCH] ath9k: Turn ath_txq_lock/unlock() into static inlines.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
These are one-line functions that just call spin_lock/unlock_bh(); turn
them into static inlines to avoid the function call overhead.

Subject: [PATCH] cfg80211: support ieee80211-freq-limit DT property
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds a helper for reading that new property and applying
limitations of supported channels specified this way.
It is used with devices that normally support a wide wireless band but
in a given config are limited to some part of it (usually due to board
design). For example a dual-band chipset may be able to support one band
only because of used antennas.
It's also common that tri-band routers have separated radios for lower
and higher part of 5 GHz band and it may be impossible to say which is
which without a DT info.

Subject: [PATCH] mac80211: initialize SMPS field in HT capabilities
ibss and mesh modes copy the ht capabilites from the band without
overriding the SMPS state. Unfortunately the default value 0 for the
SMPS field means static SMPS instead of disabled.
This results in HT ibss and mesh setups using only single-stream rates,
even though SMPS is not supposed to be active.
Initialize SMPS to disabled for all bands on ieee80211_hw_register to
ensure that the value is sane where it is not overriden with the real
SMPS state.

Also initialize rinfo->flags for legacy rates, to not
rely on the whole sinfo being initialized to zero.

Subject: [PATCH] mac80211: initialize fast-xmit 'info' later
In ieee80211_xmit_fast(), 'info' is initialized to point to the skb
that's passed in, but that skb may later be replaced by a clone (if
it was shared), leading to an invalid pointer.
This can lead to use-after-free and also later crashes since the
real SKB's info->hw_queue doesn't get initialized properly.
Fix this by assigning info only later, when it's needed, after the
skb replacement (may have) happened.

Subject: [PATCH] mac80211: fix tid_agg_rx NULL dereference
On drivers setting the SUPPORTS_REORDERING_BUFFER hardware flag,
we crash when the peer sends an AddBA request while we already
have a session open on the seame TID; this is because on those
drivers, the tid_agg_rx is left NULL even though the session is
valid, and the agg_session_valid bit is set.
To fix this, store the dialog tokens outside the tid_agg_rx to
be able to compare them to the received AddBA request.

Subject: [PATCH] mac80211: prevent skb/txq mismatch
Station structure is considered as not uploaded
(to driver) until drv_sta_state() finishes. This
call is however done after the structure is
attached to mac80211 internal lists and hashes.
This means mac80211 can lookup (and use) station
structure before it is uploaded to a driver.
If this happens (structure exists, but
sta->uploaded is false) fast_tx path can still be
taken. Deep in the fastpath call the sta->uploaded
is checked against to derive "pubsta" argument for
ieee80211_get_txq(). If sta->uploaded is false
(and sta is actually non-NULL) ieee80211_get_txq()
effectively downgraded to vif->txq.
At first glance this may look innocent but coerces
mac80211 into a state that is almost guaranteed
(codel may drop offending skb) to crash because a
station-oriented skb gets queued up on
vif-oriented txq. The ieee80211_tx_dequeue() ends
up looking at info->control.flags and tries to use
txq->sta which in the fail case is NULL.
It's probably pointless to pretend one can
downgrade skb from sta-txq to vif-txq.
Since downgrading unicast traffic to vif->txq must
not be done there's no txq to put a frame on if
sta->uploaded is false. Therefore the code is made
to fall back to regular tx() op path if the
described condition is hit.
Only drivers using wake_tx_queue were affected.
Example crash dump before fix:
Unable to handle kernel paging request at virtual address ffffe26c

Subject: [PATCH] brcmfmac: avoid maybe-uninitialized warning in
brcmf_cfg80211_start_ap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A bugfix added a sanity check around the assignment and use of the
'is_11d' variable, which looks correct to me, but as the function is
rather complex already, this confuses the compiler to the point where
it can no longer figure out if the variable is always initialized
correctly:
brcm80211/brcmfmac/cfg80211.c: In function ‘brcmf_cfg80211_start_ap’:
brcm80211/brcmfmac/cfg80211.c:4586:10: error: ‘is_11d’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This adds an initialization for the newly introduced case in which
the variable should not really be used, in order to make the warning
go away.

Subject: [PATCH] brcmfmac: proto: add callback for queuing TX data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far our core code was calling brcmf_fws_process_skb which wasn't
a proper thing to do. If case of devices using msgbuf protocol fwsignal
shouldn't be used. It was an unnecessary extra layer simply calling
a protocol specifix txdata function.
Please note we already have txdata callback, but it's used for calls
between bcdc and fwsignal so it couldn't be simply used there.
This makes core code more generic (instead of bcdc/fwsignal specific).

Firmware doesn't update beacon/Probe Response vendor IEs correctly when

driver should clear IEs when AP stopped so that the IEs in host side will

Subject: [PATCH] brcmfmac: add support for 43341 chip
This chip was already supported, but seems a device came up giving
a different chip identifier. So adding that effectively mapping to
the same firmware file as for 43340 chip.

Subject: [PATCH] brcmfmac: fix handling ssids in .sched_scan_start() callback
The ssids list in the scheduled scan request were not properly taken
into account when configuring in firmware. The hidden bit was set for
any ssid resulting in active scanning for all. Only set it for ssids
that are in the ssids list.

Subject: [PATCH] brcmfmac: make internal escan more generic
For scheduled scan we initiate an escan in firmware to obtain more
info missing from the scheduled scan notification we get from firmware.
For upcoming functionality this is also required so make it a bit
more generic.

Subject: [PATCH] brcmfmac: use provided channels for scheduled scan
User-space can provide list of channels in the schedule scan request.
This was ignored so all channels supported and allowed by the device
were used. This patch configures the device to use the channels as
listed in the request.

Subject: [PATCH] brcmfmac: remove restriction from .sched_scan_start()

In the .sched_scan_start() callback a condition was checked whether a
normal scan was ongoing. However, there is no need for this check as
it is ok to start the scheduled scan irrespective whether or not a
normal scan is ongoing.

Subject: [PATCH] brcmfmac: fix scheduled scan result handling for newer chips
The scan results for scheduled scan as retrieved from the device
have changed. A field has been added which is not needed. However,
the appended info is. Luckily they are versioned so check that to
find out the location of the appended data.

Subject: [PATCH] brcmfmac: avoid writing channel out of allocated array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Our code was assigning number of channels to the index variable by
default. If firmware reported channel we didn't predict this would
result in using that initial index value and writing out of array. This
never happened so far (we got a complete list of supported channels) but
it means possible memory corruption so we should handle it anyway.
This patch simply detects unexpected channel and ignores it.
As we don't try to create new entry now, it's also safe to drop hw_value
and center_freq assignment. For known channels we have these set anyway.
I decided to fix this issue by assigning NULL or a target channel to the
channel variable. This was one of possible ways, I prefefred this one as
it also avoids using channel[index] over and over.

During init we take care of regulatory stuff by disabling all

them is not really required (and this patch won't change any behavior).
It will on the other hand allow more detailed runtime control over
channels which is the main reason for this change.

Subject: [PATCH] brcmfmac: setup wiphy bands after registering it first
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
During bands setup we disable all channels that firmware doesn't support
in the current regulatory setup. If we do this before wiphy_register
it will result in copying set flags (including IEEE80211_CHAN_DISABLED)
to the orig_flags which is supposed to be persistent. We don't want this
as regulatory change may result in enabling some channels. We shouldn't
mess with orig_flags then (by changing them or ignoring them) so it's
better to just take care of their proper values.
This patch cleanups code a bit (by taking orig_flags more seriously) and
allows further improvements like disabling really unavailable channels.
We will need that e.g. if some frequencies should be disabled for good
due to hardware setup (design).
