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.

Subject: [PATCH] mac80211: update A-MPDU flag on tx dequeue
|
||||
|
||||
The sequence number counter is used to derive the starting sequence
|
||||
number. Since that counter is updated on tx dequeue, the A-MPDU flag
|
||||
needs to be up to date at the tme of dequeue as well.
|
||||
|
||||
This patch prevents sending more A-MPDU frames after the session has

been terminated and also ensures that aggregation starts right after the

session has been established

changing the return on success from 1 to BIT(gpio). This broke some callers

+* 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";

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.

Subject: [PATCH] ath10k: Fix failure to send NULL func frame for 10.4
|
||||
|
||||
This partially reverts 'commit 2cdce425aa33
|
||||
("ath10k: Fix broken NULL func data frame status for 10.4")'
|
||||
Unfortunately this breaks sending NULL func and the existing
|
||||
issue of obtaining proper tx status for NULL function will be
|
||||
fixed. Also update the comments for feature flag added to be
|
||||
useless and not working

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_ht: move short preamble check out of

get_rate
|

|

Test short preamble support in minstrel_ht_update_caps instead of
|
||||
looking at the per-packet flag. Makes the code more efficient.

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] 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.

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.
|
||||
|
||||

|
||||

||||

|

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.

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
|
||||
bss is down, so we move brcmf_config_ap_mgmt_ie after BSS up. And host
|
||||
driver should clear IEs when AP stopped so that the IEs in host side will
|
||||
be synced with in firmware side.

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.

For scheduled scan we initiate an escan in firmware to obtain more

Subject: [PATCH] brcmfmac: split up brcmf_pno_config() function
|
||||
|
||||
The brcmf_pno_config() function handles two configurations in

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.

callback
|

|

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: 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

unavailable channels (see brcmf_construct_chaninfo) so this predisabling
|

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).

We may want to use Open Firmware for other devices than just SDIO ones.
|

In future we may want to support more Broadcom properties so there is

really no reason for such limitation.

Call brcmf_of_probe for all kind of devices & move extra conditions to

the body of that funcion.
