Zhaoyang Liu 39df5e8233 mwifiex: get rid of BA setup helper functions
This patch removes BA setup helper routines
mwifiex_is_bastream_setup and  mwifiex_is_amsdu_in_ampdu_allowed.

Current code will use two functions to check bastream setup and
amsdu in ampdu. This patch change these functions to flags, thus
avoiding redundant spin_lock check while dequeuing TX packets.

Shengzhen Li b2713f67f7 mwifiex: avoid queue_work while work is ongoing
Current code does not check whether main_work_queue or
rx_work_queue is running when preparing to do queue_work,
this code fix add check before calling queue_work, reducing
unnecessary queue_work switch.

This change instead sets more_task flag to ensure we run main_process
superloop once again.

Nicolas Iooss a3fa71c40f wl18xx: show rx_frames_per_rates as an array as it really is
In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an
array, not a number.  This means WL18XX_DEBUGFS_FWSTATS_FILE can't be
used to display this field in debugfs (it would display a pointer, not
the actual data).  Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead.

This bug has been found by adding a __printf attribute to
wl1271_format_buffer.  gcc complained about "format '%u' expects
argument of type 'unsigned int', but argument 5 has type 'u32 *'".

Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool)

response arrives before wait_event_timeout is called, this

Sergey Ryazanov ab5e290a86 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

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.

Sergey Ryazanov 4a2f248f9e 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.

The return value in iwl_mvm_get_wakeup_status() is a bit unclear in
that it's not obvious that we don't leak fw_status in some cases.
Use fw_status directly with ERR_PTR() and return only it, that way
the compiler has a chance of proving that it's uninitialized (if it
ever is due to new changes.)

Additionally, this removes a smatch warning since smatch couldn't
figure out that fw_status can't, in fact, leak here.

Emmanuel Grumbach c22b0ff572 iwlwifi: mvm: freeze the non-shared queues when a station goes to sleep
When a station goes to sleep, we can't transmit any frame
to it. This means that until that station will wake up, a
queue that is dedicated to this station won't progress at
all. Take this into account when monitoring stuck queues
and don't account for the time the station was asleep.
This allows to mask false positives where the queues are
stuck not because of a bug, but because of the station
being asleep.

Emmanuel Grumbach e0b8d40513 iwlwifi: pcie: allow the op_mode to freeze the stuck queue timer
This allows the op_mode to let the transport know that a
queue is currently frozen and that its timer should be
stopped.
When the queue is unfrozen, its timer should be set to
expire after the remainder of the timeout has elapsed.
This can be used when stations go to sleep. When a station
goes to sleep, the op_mode can freeze the timer so that the
queue will never be considered as stuck. When the station
wakes up, the queue will be unfrozen.
This is meant to avoid false positives that would happen if
a buggy station goes to sleep for a very long time. In case
we have a dedicated queue for this station (BA agreement)
and it goes to sleep for a very long time, the queue would
rightfully be stopped during all that time. In this case,
the stuck queue timer could fire and that would be a false
positive.

Moreover, if one channel can't be stopped, stop the others

long time.

This solves a situation in which we were stuck in that flow
for way too long with a spinlock held which led to a kernel

Chub (Communication Hub, CommsHUB) is a HW component that connects to the cellular

directly of any mcc change.

The ucode notifies the driver (via this command) that it should ask for an mcc update,
and the driver sends the ucode the update mcc command to set the updated regulatory info.

The commit below didn't update the max_ht_ampdu_exponent
for the devices listed in iwl-[1-6]000.c which, in result,
became 0 instead of 8K. This reduced the size of the Rx
AMPDU from 64K to 8K which had an impact in the Rx
throughput. One user reported that because of this, his
downstream throughput droppped by a half.

If this situation ever happens, the mac80211 state machine gets
confused because it never clears csa_active. There was a separate
bug that lead to this happening with a working connection, but it
isn't very robust to try to keep the connection up in this case.

When removing the time event the CSA essentially procedure stops,
so the safest thing to do is to disconnect in this case.

Emmanuel Grumbach 4cd4b50cc2 iwlwifi: mvm: BT Coex - fix a NULL pointer exception
The commit below introduced an unsafe dereference of
mvmvif->phy_ctxt. It can be NULL even if we hold the mutex.
We can be handling a BT Coex notification while the vif has
already been unassigned. This can happen since the BT Coex
notification is hanled asynchronuously: we can have started
to handle the BT Coex notification trying to acquire the
mutex while the unassign flow already got it. The BT Coex
notification handling will wait for the mutext. I'll get it
later, but then mvmvif->phy_ctxt will be NULL.

qca6174 WLAN.RM.2.0-00073 firmware uses full rx
reordering offload and delivers Rx via a new HTT
event. The event however is incorrectly generated
in firmware and becomes overly long (with trailing
garbage). This was hitting defined CE buffer limit
that was programmed to the device and caused
device to crash upon busier Rx traffic.

Increasing the CE buffer limit for HTT Rx pipe to
2KBytes seems to be enough to workaround this
problem.

channel switch, which lead to the BI of 2000 TU from the first test
case to leak into the second one, which then didn't beacon properly.

To fix this, set data->beacon_int to zero when all stop beaconing so
that beaconing cannot be started (which was intended as 'restarted')
elsewhere.

Additionally, Jouni found that due to this 'restart' and the beacon
interval handling station interfaces would also have a needlessly
running beacon timer all the time, of course not doing anything.

To also fix the latter case only use the beacon interval when it's
actually needed, i.e. when beaconing gets enabled.

Larry Finger c8f0345586 rtlwifi: Improve handling of IPv6 packets
Routine rtl_is_special_data() is supposed to identify packets that need to
use a low bit rate so that the probability of successful transmission is
high. The current version has a bug that causes all IPv6 packets to be
labelled as special, with a corresponding low rate of transmission. A
complete fix will be quite intrusive, but until that is available, all
IPv6 packets are identified as regular.

This patch also removes a magic number.

Dedy Lansky 6eb1813764 cfg80211: add bss_type and privacy arguments in cfg80211_get_bss()
802.11ad adds new a network type (PBSS) and changes the capability
field interpretation for the DMG (60G) band.
The same 2 bits that were interpreted as "ESS" and "IBSS" before are
re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid
values are: "IBSS", "PBSS" (new) and "AP".

In order to get the BSS struct for the new PBSS networks, change the
cfg80211_get_bss() function to take a new enum ieee80211_bss_type
argument with the valid network types, as "capa_mask" and "capa_val"
no longer work correctly (the search must be band-aware now.)

The remaining bits in "capa_mask" and "capa_val" are used only for
privacy matching so replace those two with a privacy enum as well.

It can be very useful to monitor the statistics and trigger

Since the statistics are huge, add a generic trigger. When

Since there is another trigger before this one I can't add

Sometimes the firmware will have a hard coded configuration.
In this case, the driver won't find any configuration
in the firmware file, and it will have to re-start

Emmanuel Grumbach d2709ad723 iwlwifi: mvm: add framework for triggers for fw dump
Most of the time, the issues we want to debug with the
firmware dump mechanism are transient. It is then very
hard to stop the recording on time and get meaningful
data.
In order to solve this, I add here an infrastucture
of triggers. The user will supply a list of triggers
that will start / stop the recording. We have two types
of triggers: start and stop. Start triggers can start a
specific configuration. The stop triggers will be able to
kick the collection of the data with the currently running
configuration. These triggers are given to the driver by
the .ucode file - just like the configuration.

In the next patches, I'll add triggers in the code.

However the FW rate in the tx response will have the STBC
