debugfs can now report an error code if something went wrong instead of
just NULL. So if the return value is to be used as a "real" dentry, it
needs to be checked if it is an error before dereferencing it.
This is now happening because of ff9fb72bc0 ("debugfs: return error
values, not NULL"). If multiple iwlwifi devices are in the system, this
can cause problems when the driver attempts to create the main debugfs
directory again. Later on in the code we fail horribly by trying to
dereference a pointer that is an error value.

In ini debug TLVs bit 24 is set. The driver relies on it in the memory
allocation for the debug configuration. This implementation is
problematic in case of a new debug TLV that is not supported yet is added
and uses bit 24. In such a scenario the driver allocate space without
using it which causes errors in the apply point enabling flow.
Solve it by explicitly checking if a given TLV is part of the list of
the supported ini debug TLVs.

If we fail to initialize because rfkill is enabled, then trying
to do debug collection currently just fails. Prevent that in the
high-level code, although we should probably also fix the lower

It's not 100% clear that it fixes this commit, as the original

we don't really need to dump anything in this expected scenario.

mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:
@mmiowb@
@@
- mmiowb();
and invoked as:
$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done
NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

Back in commit 4d339989ac ("iwlwifi: mvm: support ibss in dqa mode")
we changed queue selection for IBSS to be:
if (ieee80211_is_probe_resp(fc) || ieee80211_is_auth(fc) ||
ieee80211_is_deauth(fc))
return IWL_MVM_DQA_AP_PROBE_RESP_QUEUE;
if (info->hw_queue == info->control.vif->cab_queue)
return info->hw_queue;
return IWL_MVM_DQA_AP_PROBE_RESP_QUEUE;
Clearly, the thought at the time must've been that mac80211 will
select the hw_queue as the cab_queue, so that we'll return and use
that, where we store the multicast queue for IBSS. This, however,
isn't true because mac80211 doesn't implement powersave for IBSS
and thus selects the normal IBSS interface AC queue (best effort).
This therefore always used the probe response queue, which maps to
the BE FIFO.
In commit cfbc6c4c5b ("iwlwifi: mvm: support mac80211 TXQs model")
we rethought this code, and as a consequence now started mapping the
multicast traffic to the multicast hardware queue since we no longer
relied on mac80211 selecting the queue, doing it ourselves instead.
This queue is mapped to the MCAST FIFO. however, this isn't actually
enabled/controlled by the firmware in IBSS mode because we don't
implement powersave, and frames from this queue can never go out in
this case.
Therefore, we got queue hang reports such as
https://bugzilla.kernel.org/show_bug.cgi?id=201707
Fix this by mapping the multicast queue to the BE FIFO in IBSS so
that all the frames can go out.

In case the driver fails to dump a memory region, and this is the last
region, then partial region would be extracted.
Solve this by setting the data to zero in case of failure.
This will cause dump to be a list of consecutive successful memory
regions and trailing zeros with no partial memories extracted.

In the old days, we could transmit with HW crypto with an arbitrary
key by filling it into TX_CMD. This was broken first with the advent
of CCMP/GCMP-256 keys which don't fit there.
This was broken *again* with the newer TX_CMD format on 22560+,
where we simply cannot pass key material anymore. However, we forgot
to update all the cases when we get a key from mac80211 and don't
program it into the hardware but still return 0 for HW crypto on TX.
In AP mode with WEP, we tried to fix this by programming the keys
separately for each station later, but this ultimately turns out to
be buggy, for example now it leaks memory when we have more than one
WEP key.
Fix this by simply using only SW crypto for WEP in newer devices by
returning -EOPNOTSUPP instead of trying to program WEP keys later.

When hostapd sends a probe response, it does not request an
acknowledgment on the probe response. This setting is propagated
to the driver and FW from mac80211, and as a result probe responses
are transmitted only once without retries. In congested
environments, this reduces the likelihood for finding the AP.
To overcome this, enable acknowledgment and retries for probe
responses, even in case no acknowledgment is requested. In such
a case the retry limit is set to 3.

AP interfaces still use some static TX queues (for probes,

correctly when the transport layer indicated the queue should be
stopped. As a result, when flushing the queues, new frames from

flushing. This ended up in an assert since trying to remove a station

In low power modes, the chip clock source for platform integrated
devices is 32kHz. It is generated internally and supplied by a crystal
oscillator. However using a 32kHz sourced from crystal oscillator
has high power penalty.
There is an option to get an external 32kHz clock from the platform. Past
experience shows that the reliability is platform dependent,
i.e. on some platforms it works good and on other it doesn’t.
Working from external clock will save 0.5 mW in sleep state, from overall
1.8mW that we have today, i.e. almost 30%.
Each OEM can enable or disable the use of the external 32kHz clock by
setting a BIOS configuration. In case the OEM configured to use 32kHz
external clock the driver will pass this indication to the FW.

When flushing TX queues no new TX should go into the system.
However, in the following scenario we get TX:
1. Queues are stopped and there are packets in overflow queue
2. Station is removed and flush begins
3. Flush empties space, and reclaim path TXes SKB from overflow
queue.
Note that the fact the queues are stopped during the process
doesn't matter - the packet will be TXed since the TX path
doesn't care if TX queues are stopped or not, just if there is
space in the queue, which there is, since we just freed a
packet.
A fix here is rather complicated, since the flow is very racy.
Change code not to warn if we are TXing from overflow TX.
In case there is TX from both overflow TX and TX path we will
miss a warning we optimally had, but we can live with that.
Make sure we don't return before overflow queue is empty, otherwise
we will think queues are empty, but they will be refilled, resulting
with assert.

Trigger field ignore_default was changed to override_trig.
The first byte of the field indicates the driver to override existing
configuration or keep the previous one
The second byte of the field indicated the driver to replace the regions
of the previous trigger or to append new regions to it.
Change the way the active triggers are maintained to support trigger
override in different apply points.
Do this by making a trigger that updates at runtime by the
triggers that are being used in the different apply points.
In case of an assert, the driver does not reconfigure the triggers
and uses the old configuration which leads to undefined behavior.
Solve this by clearing the triggers in assert recovery flow.

There are several flows in that can cause redundant allocation.
In case the driver reaches the maximum amount of blocks allowed, it
allocates the buffer and only then checks if it reached the maximum
amount of blocks and return without freeing the buffer,
causing a memory leak.
Solve this by moving the check of the amount of buffers being used
before the allocation.
In case there was an assert, the apply points are being reused,
causing that for each assert, the driver allocates a new redundant
buffer.
Solve this by adding a new is_alloc field to indicate if the driver
already allocated memory for the requested buffer.
Also, split iwl_fw_dbg_buffer_allocation function into
iwl_fw_dbg_buffer_allocation and iwl_fw_dbg_buffer_apply
to increase the clearity of the flow.

Recently we started to send the WEP keys to the firmware so
that we could use hardware Tx encryption also on newer
devices that require the keys to be installed in the firmware
for encryption (as opposed to older devices that can get
the key in the Tx command for each Tx).
When we implemented that, we forgot to remove the key when
we remove a station leading to a situation where a station
that connects and disconnects a lot of times exhausts the
key database inside the firmware.
A fix was made for that, but we always removed the same
key: mvmvif->ap_wep_key which means that we removed the
same key entry in the firmware. This can make sense since
in WEP, the key is the same for all the stations, but the
internal implementation of iwl_mvm_set_sta_key and
iwl_mvm_remove_sta_key assumes that each station uses a
different key in the firmware's key database.
So now we got to the situation where we have a single
ieee80211_key_conf instance that means, a single
ieee80211_key_conf.hw_key_idx index for several stations
and hence for several keys.
ieee80211_key_conf.hw_key_idx is set to 0 when the first
station associates, and then it is overwritten to 1 when
the second station associates which is a buggy of course.
This led to the following message upon the removal of the
second station:
iwlwifi 0000:00:03.0: offset 1 not used in fw key table.
WARNING: CPU: 2 PID: 27883 at net/mac80211/sta_info.c:1122 __sta_info_destroy_part2+0x16b/0x180 [mac80211]

nl80211_del_station+0xe0/0x1f0 [cfg80211]
Fix this by copying the ieee80211_key_conf structure for
each and every station. This is the easiest way to properly
remove the keys with the right index. Another solution
would have been to allow several stations to use the same
key offset in the firmware. That would require to change
the way we track keys in iwlmvm and not really worth it.
Also, maintain correctly fw_key_table when we add a key
for the multicast station.
Remove the key when we remove the multicast station.

In the regular flow, when we receive an assert, ieee80211_reconfig is
called which reconfig the driver using iwl_mvm_mac_start.
iwl_mvm_mac_start is clearing the restart bit and does dump collection.
Prior to setting the device up, ieee80211_reconfig does not call
iwl_mvm_mac_start since there is nothing to reconfig and we miss the
dump collection of the assert.
solve it by checking the restart bit before we stop the device
and trigger a dump collection in case it is set.
note that we don't need to do it in the fmac case since in fmac
assert flow in iwl_fmac_nic_error we call iwl_fw_dbg_collect_desc

TX path lock was introduced in order to prevent out of order
invocations of TX.
This can happen in the following flow:
TX path invoked from net dev
Packet dequeued
TX path invoked from RX path
Packet dequeued
Packet TXed
Packet TXed
However, we don't really need a lock. If TX path is already
invoked from some location, other paths can simply abort their
execution, instead of waiting to the first path to finish, and
then discover queue is (likely) empty or stopped.
Replace the lock with an atomic variable to track TX ownership.
This simplifies the locking dependencies between RX and TX paths,
and should improve performance.

Clean up the LDBG config command to not be called "continuous

recording implementation completely since it was only used for
store & forward architectures.
This also fixes a bug at least in iwl_fw_dbg_buffer_allocation()
because what's now "__le32 type" (matching the firmware) used to
be "__le16 enable_recording", so the buffer allocation config
sub-struct would erroneously have started at the wrong offset.
In the other cases this didn't actually lead to a bug as other
bytes in pad[] were all zeroes, so accessing the 16-bit value as
a 32-bit value wouldn't make a difference (in little endian.)

Move to use the new mac80211 TXQs implementation. This has
quite a few benefits for us. We can get rid of the awkward
mapping of DQA to mac80211 queues. We can stop buffering
traffic while waiting for the queue to be allocated. We can
also use mac80211 AMSDUs instead of building it ourselves.
The usage is pretty simple:
Each ieee80211_txq contains iwl_mvm_txq. There is such a
queue for each TID, and one for management frames. We keep
having static AP queues for probes and non-bufferable MMPDUs,
along with broadcast and multicast queues. Those are being
used from the "old" TX invocation path - iwl_mvm_mac_tx.
When there is a new frame in a TXQ, iwl_mvm_mac_wake_tx is
being called, and either invokes the TX path, or allocates
the queue if it does not exist.
Most of the TX path is left untouched, although we can consider
cleaning it up some more, for example get rid of the duplication
of txq_id in both iwl_mvm_txq and iwl_mvm_dqa_txq_info.

Since IWLWIFI doesn't depend on MAC80211 anymore, it needs to depend
on CFG80211, because it uses a few symbols from it. Add the
dependency on CFG80211 accordingly.
Additionally, make IWLWIFI_LEDS depend on IWLMVM or IWLDVM, since it
doesn't need mac80211 but must be used for these.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This issue was detected with the help of Coccinelle.

The FW expects to get the ppe value for each NSS-BW pair in the same
format as in the he phy capabilities IE, which means that a value of 0
implies ppe should be used for BPSK (mcs 0). If there are no PPE
thresholds in the IE, or if for some NSS-RU pair there's no threshold
set for it (this could happen because it's a variable-sized field), it
means no PPE should not be used for that pair, so the value sent to FW
should be 7 which corresponds to "none".

The firmware changed the PHY data API, so follow suit.
Some data is now available even for HT/VHT frames, so
the info type in the metadata was changed. This change
isn't backwards compatible, but
1) the firmware with the old API was never released;
2) the only overlap in the info type field is from the
old type of TB to the new of HT, so this basically
just means that with older FW and newer driver the
data will be considered missing.
While at it, remove the extra code to set the LTF syms
corresponding to the streams and use the data from the
device instead - we don't really need this in any case
other than when we have it from the device.
As the new API gives use the spatial reuse 1-4 fields
for trigger-based PPDUs, also expose that to radiotap.

When removing the driver, the following flow can happen:
1. host command is in progress, for example at index 68.
2. RX interrupt is received with the response.
3. Before it is processed, the remove flow kicks in, and
calls iwl_pcie_txq_unmap. The function cleans all DMA,
and promotes the read pointer to 69.
4. RX thread proceeds with the processing, and is calling
iwl_pcie_cmdq_reclaim, which will print this error:
iwl_pcie_cmdq_reclaim: Read index for DMA queue txq id (0),
index 4 is out of range [0-256] 69 69.
Detect this situation, and avoid the print. Change it to
warning while at it, to make such issues more noticeable

When traffic load is not low or low latency is active, TCM schedules
re-evaluation work so in case traffic stops TCM will detect that
traffic load has become low or that low latency is no longer active.
However, if TCM is paused when the re-evaluation work runs, it does
not re-evaluate and the re-evaluation work is no longer scheduled.
As a result, TCM will not indicate that low latency is no longer
active or that traffic load is low when traffic stops.
Fix this by forcing TCM re-evaluation when TCM is resumed in case
low latency is active or traffic load is not low.

This function is only half-used by mvm (i.e. only the nvm_version part
matters, since the calibration version is irrelevant), so it's
pointless to export it from iwlwifi. If mvm uses this function, it
has the additional complexity of setting the calib version to a bogus
value on all cfg structs.
To avoid this, move the function to dvm and make a simple comparison
