Subject: iwlwifi: mvm: synchronize TID queue removal

When we mark a TID as no longer having a queue, there's no
guarantee the TX path isn't using this txq_id right now,
having accessed it just before we reset the value. To fix
this, add synchronize_net() when we change the TIDs from
having a queue to not having one, so that we can then be
sure that the TX path is no longer accessing that queue.

Subject: iwlwifi: mvm: remove queue_info_lock

All the queue management code runs under mvm->mutex, so there are
only very few cases of accessing the data structures without it:
 * TX path, which doesn't take any locks anyway
 * iwl_mvm_wake_sw_queue() and iwl_mvm_stop_sw_queue() where we
   just (atomically) read a bitmap, so the lock isn't needed.

Therefore, we can remove the spinlock. This enables some cleanup
in the ugly locking in iwl_mvm_inactivity_check().

Subject: iwlwifi: trans: Clear persistence bit when starting the FW

In D3 suspend flow in 9260 gen2 HW, the NIC receives two PERST signals.
The first PERST is expected and indicates the device on coming resume flow.
The second PERST causes FW restart FW restart.
In order to avoid this issue, the FW set the persistence bit on.
Once this bit is set, the FW ignores reset attempts.
The problem is when the FW gets assert during D3 and then the persistence
bit is set and causes the FW to ignore reset.
To handle this issue, the FW opens the preg bit which allows access
to the persistence bit, so that the driver clear the persistence bit
and reset the NIC.

The flow is as follows:
the driver checks if the persistence bit is set.
If the bit is set, the driver checks if he can clear the bit.
If the driver can not clear the bit then there is no point to continue
configuring the NIC since it will fail.

The fix was added is in start HW flow instead of the resume flow since in
general, if the persistence bit is set, the driver can not start the FW.
So it is good to check it when we start configuring the NIC.

The driver does not need to close the preg bit since the FW close it
during the start flow.

Subject: iwlwifi: fw: do not set sgi bits for HE connection

If the association supports HE, HT/VHT rates will never be used for Tx
and therefore there's no need to set the sgi-per-channel-width-support
bits, so don't set them in this case.

Subject: iwlwifi: mvm: toggle tx antenna if tx fails during connection
 establishment

If tx fails during connection establishment, try another antenna for
the next tx. This will increase the chance to establish connection if
one of the antennas is blocked.  Note that the antenna is toggled even
when failing to tx data frames since connection establishment may use
EAPOLs for 802.1X authentication/ 4 way handshake.

Subject: iwlwifi: dbg: avoid passing trigger around

The trigger structure is being passed around, when
all we care about is whether to dump only monitor
or not. Pass a bool instead.

Subject: iwlwifi: mvm: add description to a few generic assert numbers

FW asserts 0x70, 0x71, and 0x73 all just mean that the real error
happened in another MAC, and to look there for the problem. Add their
descriptions to the assert number lookup table so users get a nicer
error message in the logs.
Also, since the 4 most-significant bits of the assert number are
dynamic, and depend on which MAC the assert occurred on, ignore those
bits when looking up the assert name.

Subject: iwlwifi: mvm: Send non offchannel traffic via AP sta

TDLS discovery response frame is a unicast direct frame to the peer.
Since we don't have a STA for this peer, this frame goes through
iwl_tx_skb_non_sta(). As the result aux_sta and some completely
arbitrary queue would be selected for this frame, resulting in a queue
hang.  Fix that by sending such frames through AP sta instead.

Subject: iwlwifi: fw: use helper to determine whether to dump paging

Logic is there twice, and we'll need a third place
soon for ini dumping. In addition move the dumping
to a function, also to enable reuse.

Subject: iwlwifi: dbg: don't limit dump decisions to all or monitor

Currently opmode is limited to asking transport to either
dump all the dumps configured at startup, or monitor only.
Instead, pass to transport a bitmask, to allow flexibility.

Subject: iwlwifi: dbg: split fifos dump

Split the dump of RXF and TXF. This is in order to
enable code reuse for INI, which may decide to dump
only RXF and not TXF, and vice versa.

Subject: iwlwifi: fix cfg structs for 22000 with different RF modules

We have to choose different configuration and different firmwares
depending on the external RF module that is installed.  Since the
external module is not represented in the PCI IDs, we need to change
the configuration at runtime, after checking the RF ID of the module
installed.  We have a bit of a mess in the code that does this,
because it applies cfg's according to the RF ID only, ignoring the
integrated module that is in use.

Fix that for some devices by adding correct configurations for them
and not ignoring the integrated module's type when making the
decision.

Subject: iwlwifi: add fw dump upon RT ucode start failure

FW dump was missing in case the RT FW ucode
section failed to load. This failure happens when
the RT section of the FW file is corrupted.

Subject: iwlwifi: mvm: add support for TWT capabilities

We need to check the TWT support of the peer and to
propagte the capability to the firmware.
The current implementation will enable TWT only if the TWT
support is advertised in the HE CAP IE and in the Extended
Capability IE.

From f14cda6f3b31347d1d814839d7e671dea749f1b0 Mon Sep 17 00:00:00 2001
From: Sara Sharon <sara.sharon@intel.com>
Date: Thu, 17 May 2018 10:14:30 +0300
Subject: iwlwifi: trans: parse and store debug ini TLVs

The new debug ini TLVs can be either packed into firmware
binary or written in external file. Support loading them
from both. Store the data per apply point. Apply point is
a point during driver runtime, where the TLV becomes active.
For example, a trigger of hardware error may be configured
to collect a subset of data pre-alive, as a opposed to HW
error that occurs after alive.

Subject: iwlwifi: trans: support loading ini TLVs from external file

Support loading and storing ini TLVs from external
file. Those TLVs are appended to the default TLVs,
so store them separately.

Subject: iwlwifi: dbg: add apply point logic

Add a function to be called when apply point occurs.
For each of the TLVs, the function will perform the
apply point logic:
- For HCMD - send the stored host command
- For buffer allocation - allocate the memory and send the
  buffer allocation command
- For trigger and region - update the stored configuration

Subject: iwlwifi: add debugfs file to read fw debug data recording

FW debug data will oneshot read all data available in DRAM
and fill the supplied user buffer. In case the read request
is greater than the new data in DRAM, the driver will write
all data it has and return the buffer immediately.

Subject: net: documentation: build a directory structure for drivers

Documentation/networking/ is full of cryptically named files with
driver documentation.  This makes finding interesting information
at a glance really hard.  Move all those files into a directory
called device_drivers (since not all drivers are for device) and
fix up references.

RFC v0.1 -> RFC v1:
 - also add .txt suffix to the files which are missing it (Quentin)

Subject: iwlwifi: don't define OTP_LOW_IMAGE_SIZE per family, but per size

Using OTP_LOW_IMAGE_SIZE_FAMILY_8000/9000/22000 only obfuscates the
actual values, since these 3 are the same.  Redefine the values per
size so it's easier to understand and compare the different
configurations.

Subject: iwlwifi: remove useless NVM_HW_SECTION_NUM_FAMILY_* macros

These macros are useless because each one of them is used only once
and the element they are assigned to is already pretty clear about
what they mean, "nvm_hw_section_num".

Subject: iwlwifi: move iwl_nvm_check_version() into dvm

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
of the nvm_version in mvm instead.

Subject: iwlwifi: remove all unnecessary occurrences of nvm_calib_ver

Now that nvm_calib_ver is not checked in opmodes other than dvm, we
can remove it from all irrelevant configurations.

Subject: iwlwifi: mvm: force TCM re-evaluation on TCM resume

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.

Subject: iwlwifi: pcie: fix erroneous print

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
in the future.

Subject: iwlwifi: mvm: change PHY data RX for HE radiotap

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.

Subject: iwlwifi: mvm: add L-SIG length to radiotap

We may have the L-SIG length depending on the phy_data info type;
add it to radiotap when we do.

Move getting the phy_data out one layer up and the info type into
it so we can use this data more generically. We need to call the
iwl_mvm_rx_he() function for other reasons as well, so can't just
combine all of that into something like iwl_mvm_parse_phy_data().

command len is set too early in the code, since when building

We used to have many versions of statistics notification
coming from the firmware. In one of the cleanup patches,
we forgot to clean the code that checks if data->general
is set. Since it is always set, remove the check.

Subject: iwlwifi: pcie: use iwl_tx_cmd_gen2 and not iwl_tx_cmd

When building AMSDU for gen2, code uses iwl_tx_cmd. The only
updated field is len, which is in the same location, so it
is not a bug. However, it is a bit confusing and error prone,
so change it.

Subject: iwlwifi: mvm: remove dead code

In iwl_mvm_tx_skb_non_sta(), in case of managed interface,
the AP station was supposed to be used for multicast frames
instead of the auxiliary station to avoid frames possibly
sent to an absent P2P GO. However, when moving to DQA mode,
this was broken as no valid queue was assigned. This is fixed
by a recent patch that directs all non-offchannel traffic to
ap station earlier in the TX path. However, the broken, and
now dead code, remained. Remove it.

Assigning mvmsta to be NULL when we are about to exit the
function is pointless. Remove it. Move the variable declaration
to the scope it is used.

Subject: iwlwifi: mvm: fix setting HE ppe FW config

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".

Subject: iwlwifi: pcie: lock txq a bit later in reclaim code

In reclaim code, we don't need to take the queue lock for
waking the queue. The code section is executed only when
the tx path is stopped, and since the reclaim path is not
executed in parallel to itself, no one can update the queue
pointers, and accessing them is safe without a lock.

Subject: iwlwifi: mvm: clean up SSN incrementation

Sometimes, due to SCD bug, we need to start the queue with an
higher SSN. The queue allocation function currently increments
the SSN in the packet itself, but it is pointless, since this
value is overridden later by iwl_mvm_tx_mpdu with the value
from mvmsta->tid_data[tid].seq_number. Updating tid data is
sufficient.

Subject: iwlwifi: mvm: d3: use struct_size() in kzalloc()

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.

Subject: iwlwifi: make IWLWIFI depend on CFG80211

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.

Subject: iwlwifi: mvm: advertise support for TWT in the Extended Capability IE

We want to advertise support for TWT in the Extended
Capability IE. Since we don't want to set the bits for all
the interface types, define an interface specific
configuration.

Subject: iwlwifi: pcie: recognize NICs with hw_rev 0x364 correctly

Some devices with PCI ID 0x2723, which is supposed to be 22260, are
actually not.  So we need to differentiate them by checking the hw_rev
and change the cfg accordingly.

1. check the peer's RX DCM capabilities (since we TX)
2. do not set DCM_NSS_2 since we do not support it

Subject: iwlwifi: mvm: fix firmware statistics usage

The new (CDB) statistics API is used by non-CDB devices
as well. Look at the right TLV flag to know which version
of the statistics notification to use.
To avoid confusion, remove the _cdb suffix from the
structure name.
While at it, remove a structure that was never used.

Subject: iwlwifi: remove support for 9000 A-step devices

We don't support 9000 A-step devices anymore, so we can remove support
for loading both the a0/a0 and a0/b0 FWs.

Subject: iwlwifi: mvm: make NVM access actually fail on failures

On any failure, including if we crash the firmware or get garbage
data, we currently ignore this and pretend the OTP was empty.
Clearly, this isn't typically the case.

In cases other than the firmware saying it can't read the requested
section, or the section having ended, make the access actually fail
and trickle the error up through the layers to fail init.

Subject: iwlwifi: mvm: support mac80211 TXQs model

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.

Subject: iwlwifi: mvm: support mac80211 AMSDU

Support getting mac80211 building AMSDUs for us. Remove GSO
support from mvm - we don't need it anymore.

Subject: iwlwifi: mvm: fix values in the table example
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We erroneously had some values for NGI in the table we give as an
example in rs_fill_rates_for_column(), when they should be SGI.
Change them so that they match what we say.

Subject: iwlwifi: mvm: bring back mvm GSO code

We have a slightly better TCP performance with GSO.
Add it back, it can co-exist with the code that builds
AMSDUs in mac80211.

When a time event for a P2P Device interface is done, it is possible
that there is still a frame pending for transmission that should be
flushed.

Set the IWL_MVM_STATUS_NEED_FLUSH_P2P to indicate to the ROC worker
that P2P Device station queue need also to be flushed.

Subject: iwlwifi: memcpy from dev_cmd and not dev_cmd->hdr

Klocwork complains about copying from dev_cmd->hdr if
copying more than 4 bytes since it means part of the
copy is from the next field. This isn't a real bug,
but for not failing Klocwork next time - fix this.

Subject: iwlwifi: iwlmvm: in monitor NDP notif take the NSS from rx_vec

Take the NSS value from 'rx_vec' rather than from 'rate_n_flags'.
The rate_n_flags has only 2 bits for the NSS giving a max of 4SS
(0 = 1SS etc.). Since there may be up to 8SS use the rx_vec which
has 3 bits for the NSS.
While at it, fix the rx_vec array to length of 2.

With just %16, it means 16 characters padding, but we really
don't want to print "0x         1F4547B", but instead want to
have this filled with zeroes, so we need the 0.

Subject: iwlwifi: mvm: read IWL_RX_MPDU_PHY_SHORT_PREAMBLE only for CCK

Due to a general shortage of RX API bits, the firmware is going
to reuse this bit on non-CCK frames to mean something else. Use
it only on CCK frames to prepare for that change.

Subject: iwlwifi: pcie: align licensing to dual GPL/BSD

These files have a long history of code changes, but analysing
the remaining code leads to having only a few changes that are
not already owned by Intel, notably from
 - Andy Lutomirski <luto@amacapital.net>
 - Joonwoo Park <joonwpark81@gmail.com>
 - Kirtika Ruchandani <kirtika@chromium.org>
 - Rajat Jain <rajatja@google.com>
 - Stanislaw Gruszka <sgruszka@redhat.com>
remaining in the code today.

Note that
 - I myself was working for Intel and for any possibly code
   that might be before my employment there give permission
 - Wizery employees were working for Intel

More specifically, we identified the following commits that
(partially may) remain today:

25c03d8e8c13 Joonwoo Park <joonwpark81@gmail.com>      ("iwlwifi: do not schedule tasklet when rcv unused irq")
f36d04abe684 Stanislaw Gruszka <sgruszka@redhat.com>   ("iwlwifi: use dma_alloc_coherent")
387f3381f732 Stanislaw Gruszka <sgruszka@redhat.com>   ("iwlwifi: fix dma mappings and skbs leak")
2624e96ce16b Stanislaw Gruszka <sgruszka@redhat.com>   ("iwlwifi: fix possible data overwrite in hcmd callback")
bfe4b80e9f73 Stanislaw Gruszka <sgruszka@redhat.com>   ("iwlwifi: always check if got h/w access before write")
d536c32b45d2 Andy Lutomirski <luto@amacapital.net>     ("iwlwifi: pcie: log when waking the NIC for hcmd submission fails")
a6d24fad00d9 Rajat Jain <rajatja@google.com>           ("iwlwifi: pcie: dump registers when HW becomes inaccessible")
fb12777ab59b Kirtika Ruchandani <kirtika@chromium.org> ("iwlwifi: Add more call-sites for pcie reg dumper")
3a73a30049f2 Stanislaw Gruszka <sgruszka@redhat.com>   ("iwlwifi: cleanup/fix memory barriers")
aa5affbacb24 Stanislaw Gruszka <sgruszka@redhat.com>   ("iwlwifi: dump stack when fail to gain access to the device")

Align the licenses with their permission to clean up and to
make it all identical.

Subject: iwlwifi: mvm: clean up LDBG config command usage

Clean up the LDBG config command to not be called "continuous
recording", and while at it actually remove the 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.)

Sometimes we want to debug issues related to the regulatory blob in
the NVM.  To make that easier, add a debugfs entry to export it
together with the other nvm blobs we export.

Subject: iwlwifi: mvm: pre-initialize alive_data in wait_alive()

The function we pass to the wait alive notification procedure may may
not even get called if the timeout occurs before the function is
called.  To prevent accessing unitialized data in alive_data, pre-set
it to zero in the declaration.  Found by static analyzers.

Subject: iwlwifi: calculate pointers from out_cmd instead of out_cmd->hdr

The out_cmd structure starts with a header, so there's no need to use
&out_cmd->hdr, out_cmd alone is enough.  We use this when calculating
other addresses and klocwork gets confused with that because it thinks
we are trying to access hdr (as an array) beyond its size.

Subject: iwlwifi: mvm: remove sta key on wep ap

If WEP is used, no one removes the STA key upon STA
removal, leading to a situation where after 16
connect/disconnects - the AP could no longer decrypt
incoming data frames since iwl_mvm_set_fw_key_idx()
called from iwl_mvm_set_sta_key() during association
returns STA_KEY_IDX_INVALID, thus not setting the key
for that connecting STA.

Fix this by removing the key in the driver when the
STA is removed.

Subject: iwlwifi: mvm: add an option to dereference vif by id

Currently whenever we get firmware notification with mac id,
we iterate over all the interfaces to find the ID. This is a
bit cumbersome. Instead, adding an array of RCU pointers, like
we have for station IDs. This is not expensive space wise
since we have only up to 4 active MACs, and not complicated
code wise, since we have a clear point to init and de-init it.

Subject: iwlwifi: mvm: fix A-MPDU reference assignment

The current code assigns the reference, and then goes to increment
it if the toggle bit has changed. That way, we get

Toggle  0  0  0  0  1  1  1  1
ID      1  1  1  1  1  2  2  2

Fix that by assigning the post-toggle ID to get

Toggle  0  0  0  0  1  1  1  1
ID      1  1  1  1  2  2  2  2

Subject: iwlwifi: mvm: get rid of tx_path_lock

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.

the firmware in any way, and most likely never worked. Remove all
of it so it can be reintroduced properly.

Subject: iwlwifi: dvm: remove useless condition

If we're in the else branch of checking "tt->state == IWL_TI_CT_KILL"
so there's no point in checking "tt->state != IWL_TI_CT_KILL" again.

Subject: iwlwifi: mvm: Disconnect on large beacon loss

Some buggy APs stop sending beacons, but continue to ack our null data
packets or even run some traffic. It's better not to stick connected to
such an AP forever, so disconnect after some larger beacon loss
threshold is crossed.

Subject: iwlwifi: mvm: implement CSI reporting

Implement CSI (channel estimation matrix) reporting in the mvm
driver, if the firmware has the capability.

Currently only a debugfs API is provided as the API is still
under discussion.

For now, RX aggregation must be disabled to use this feature
on data frames as we haven't found a good way to attach the
data to A-MPDUs, given complexities with multi-queue.

From 57e861d9362ed303ac5c0df1bc11760979de9f55 Mon Sep 17 00:00:00 2001
From: David Spinadel <david.spinadel@intel.com>
Date: Sun, 18 Nov 2018 18:01:43 +0200
Subject: iwlwifi: mvm: Change FW channel info API

Change iwl_fw_channel_info structure so it can have channel number
greater than 255. This is needed for 6 GHz channel numbers.
Change all relevant structs and member accesses accordingly.
The new API is indicated by a TLV capability bit.

Subject: iwlwifi: mvm: freeze management TXQ timer when station goes to sleep

We maintain a timer for each Tx queue to detect stalls and
be able to recover / debug.
When we work in AP mode, we can freeze the Tx queue timer if
a station goes to sleep, because we don't want to warn about
stalls that are caused by faulty clients that don't wake up
on time.
This mechanism was applied to the queues of the clients, but
the management queue was omitted. Fix that.

Subject: iwlwifi: mvm: disable completely low latency mode with debugfs

We introduce a new state for latency, force mode, in force mode
you can enable always to be in low latency or always to be in non
low latency.

This is required for test mode in max TpT test.

Subject: iwlwifi: mvm: include configured sniffer AID in radiotap

In order to make more sense out of the captured radiotap data e.g.
when the configured AID changes, add the currently configured AID
to the radiotap data as a vendor extension field.

This is made race-free by updating the included value from inside
the RX path (using a notification wait) for the command response
from the firmware, which thus means it's serialized with frame RX.

Subject: iwlwifi: trigger dump on assert prior to setting the device up

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
so we can be sure that there will a dump collection in
iwl_fmac_stop_device.

Subject: iwlwifi: dbg_ini: allocate dram buffer with proper flags

Use the same flags we use in the legacy buffer allocation.
Missing __GFP_NOWARN will cause an unwanted warning incase
we fail to allocate.
Missing __GFP_ZERO will give a buffer initially filled with
garbage which can make debug difficult in case our wrap count is zero.

Subject: iwlwifi: dbg_ini: properly handle ini user trigger

in case of a user trigger while ini is enable we change
FW_DBG_TRIGGER_USER to IWL_FW_TRIGGER_ID_USER_TRIGGER in
iwl_fw_dbg_collect and then again we attempt to do so in
_iwl_fw_error_ini_dump which causes to abort the dump.

Fix it by removing the second check in _iwl_fw_error_ini_dump.

never do something different based on this.

Subject: wireless: prefix header search paths with $(srctree)/

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].

To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.

Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

I also removed one header search path in:

  drivers/net/wireless/broadcom/brcm80211/brcmutil/Makefile

I was able to compile without it.

Subject: iwlwifi: fix bad dma handling in page_mem dumping flow

Prior to gen2 we allocate the paging memory via alloc_pages
which requires passing ownership on the memory between the
cpu and the device using dma_sync_single_for_cpu and
dma_sync_single_for_device.

Add missing dma_sync_single_for_device in iwl_dump_paging
after copying the memory.

since gen2, we allocate the paging memory using dma_alloc_coherent
which does not need passing ownership between the cpu and device.

Remove unneeded call to dma_sync_single_for_cpu in
iwl_trans_pcie_dump_data prior to copying the memory.

Subject: iwlwifi: differentiate between alive timeout and alive flow failure

There are two cases that can cause the alive flow to fail,
an assert or a timeout.
Currently we mask any incoming asserts when we wait for alive.

Solve this by differentiating between the two cases:
1. Let the regular error handling to handle a received assert
2. Do a dump collection in the case of a timeout

Fixes: f38efdb29389 ("iwlwifi: add dump collection in case alive flow fails")

Subject: iwlwifi: Fix pre operational dumping flows

There are several dumping flows in the driver in case of a fail
prior to operational.

In some cases we get 2 dumps while in others we get none.

Fix this by uniting the different flows.
Add a different dump type to driver triggered dumps in case we want
a dump but did not got assert, and make all dumping go through
iwl_fw_dbg_collect_desc to avoid multiple dumps.

Subject: iwlwifi: mvm: add fall through comments where needed

Some switch-cases were missing a fall through comment, so the compiler
may warn.  Fix that by adding the comments where needed.  In other
cases there was more text in the comment, which the compiler doesn't
recognize, so either remove the extra text or move it to a separate
comment line as appropriate.

From 28916a165aa7e0ceddedabf722808881ba6a3b03 Mon Sep 17 00:00:00 2001
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Mon, 3 Dec 2018 20:13:27 +0200
Subject: iwlwifi: mvm: fix AP mode in WEP

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]
RIP: 0010:__sta_info_destroy_part2+0x16b/0x180 [mac80211]
 Call Trace:
  __sta_info_destroy+0x2a/0x40 [mac80211]

  ieee80211_del_station+0x1d/0x30 [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.

Subject: iwlwifi: dbg_ini: remove redundant dram buffer allocation

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.

Subject: iwlwifi: move config structs to C file

Even if they're static const, there's no need to duplicate
the structs every time they're included and used. Move them
to an appropriate C file instead.

Also remove useless parentheses along the way.

Subject: iwlwifi: mvm: don't hide HE radiotap data in SKB

Hiding the HE radiotap data for further processing of the SKB just
caused another bug when adding the L-SIG data. Simply stop doing
this and adjust the skb->data pointer accordingly when we need to
get the 802.11 header.

While at it, also verify and fix the data alignment, we need to add
2 bytes padding with the vendor data to ensure the whole length of
all radiotap headers is a multiple of 4.

Subject: iwlwifi: dbg_ini: align struct iwl_fw_ini_region_cfg to the FW

New fields were added to struct iwl_fw_ini_region_cfg.
add those field and apply the changes the result from this change

offset field is used to differentiate between the different LMACs
and any memory access to the region addresses should be
base_addr + offset.

A fifo struct is to hold the meta data needed for fifo regions

Also move range_data_size and num_of_ranges into a struct under the
union to be aligned to the struct in the FW.

Subject: iwlwifi: dbg_ini: implement paging memory dump

Implement paging memory dump in the new dump mechanism.
To support this change, moved iwl_self_init_dram strcut from trans_pcie
to trans so that it will accessible via fw_runtime.

Subject: iwlwifi: fix send hcmd timeout recovery flow

Both iwl_trans_fw_error and iwl_force_nmi initiate async recovery flow.
Calling them both is redundant and causing a race.

Solve this by removing the call to iwl_trans_fw_error.

Subject: iwlwifi: refactor NIC init sequence

The typical sequence of setting INIT_DONE and then waiting
for clock stabilisation is going to need a new workarounds,
so first of all refactor it.

Subject: iwlwifi: mvm: fix RFH config command with >=10 CPUs

If we have >=10 (logical) CPUs, our command size exceeds the
internal buffer size and the command fails; fix that by using
IWL_HCMD_DFL_NOCOPY for the command that's allocated anyway.

While at it, also fix the leak of cmd, and use struct_size()
to calculate its size.

Subject: iwlwifi: pcie: fix emergency path

Allocator swaps the pending requests with 0 when it starts
working. This means that relying on it n RX path to decide if
to move to emergency is not always a good idea, since it may
be zero, but there are still a lot of unallocated RBs in the
system. Change allocator to decrement the pending requests on
real time. It is more expensive since it accesses the atomic
variable more times, but it gives the RX path a better idea
of the system's status.

From fc36ffda326706b21f70a4aff0c77d9bc94c4f0a Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Wed, 5 Dec 2018 11:33:34 +0100
Subject: iwlwifi: mvm: support FTM initiator

Add support for FTM initiator, i.e. peer measurements with FTM
if the firmware supports FTM.

Additionally, add two defines we depend on in
include/linux/ieee80211.h.

Subject: iwlwifi: mvm: clean up NO_PSDU case

We now no longer have any special code in
iwl_mvm_pass_packet_to_mac80211(), so don't
need to pass NO_PSDU packets through it.
Stop doing so and clean up the code there.

Subject: iwlwifi: receive umac and lmac error table addresses from TLVs

TLV 54 holds umac debug related addresses.
TLV 55 holds lmac debug related addresses.
These TLVs aim to replace the alive notification data in the future.

Parse and keep error table addresses received from the TLVs
for both lmac and umac and use these addresses instead of the pointer
received from alive notification.

The feature supports only unified image.

From b61a6610922272dce0cf4dc43b576919b7b0593c Mon Sep 17 00:00:00 2001
From: Shahar S Matityahu <shahar.s.matityahu@intel.com>

Subject: iwlwifi: dbg_ini: rewrite trigger flow and align to FW API changes

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.

From f130bb75d8817c560b48c4d1a0e5279968a0859d Mon Sep 17 00:00:00 2001

Subject: iwlwifi: add FW recovery flow

Add new API and TLV for the ability to send commands in the beginning
and end of reset flow.

The full flow of recovery is:

1. While loading FW, get address (from the TLV) of target buffer
   to read in case of reset
2. If an error/assert happens read the address data from step 1.
3. Reset the HW and load the FW.
4. Send the data read in step 2.
5. Add station keys
6. Send notification to FW that reset flow is done.

The main use of the recovery flow is for support in PN/SN recovery
when offloaded

Subject: iwlwifi: do not fail on large amount of channels

Until supporting UHB (ultra high band) channels for
devices AX210, do not fail if number of channels reported
by firmware is greater than NL80211_MAX_SUPP_REG_RULES.
The Driver in that case will use only the non-UHB channels.

Subject: iwlwifi: mvm: Fix possible NULL pointer dereference

iwl_mvm_te_clear_data() is called for cleanup in case sending
the HOT_SPOT_CMD failed. However, in case sending the command
caused a fw error and restart (e.g. if the command is not supported)
then the te_data pointer may no longer be valid, which leads to
a NULL pointer dereference.

Fix it by checking that the te_data pointer is not NULL before
dereferencing it.

Subject: iwlwifi: pcie: fix TX while flushing

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.

Subject: iwlwifi: mvm: add support for 32kHz external clock indication
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

Subject: iwlwifi: dbg: temporarily skip periphery dump for AX210 devices

Many periphery addresses have changed in AX210 devices.
Until sorting out which peripheries should be dumped, skip
that step for now.

Subject: iwiwifi: mvm: Fix FW scan concurrency support assumptions

- The FW supports up to 4 concurrent scans, so adjust the definitions
  accordingly.
- Only a single periodic scan is supported, so enforce it in the code.

Subject: iwlwifi: mvm: add support for new FTM fw API

The FTM new API uses API TLV bit 15. The driver mistakenly uses
this bit for beacon filter API, although no TLV was assigned for
the beacon filter API. For now, make beacon filter use bit 16
instead (not set by the fw anyway). Once a TLV is assigned to the
beacon filter API it should be updated.

Subject: iwlwifi: mvm: fix HE radiotap data4 for HE-TB PPDUs

In HE-TB PPDUs (labeled HE-TRIG in radiotap), we were overwriting
the data4.spatial_reuse_1 field with the spatial reuse data that
the firmware gives us for SU/MU PPDUs. Fix that by moving that,
we are already setting the data4.spatial_reuse_{1,2,3,4} fields
in the TB PPDU case.

We don't support A-step for some device combinations anymore.  So
change them to use B-step, renaming and reorganizing the config
structures.  Additionally, fix one device that was using the wrong
configuration.

Subject: iwlwifi: properly use delay option in dump trigger flow

Fix several issues related to dump delay:
1. In legacy dump trigger, use stop_delay field instead of trig_dis_ms.
2. ini delay is messured in usec so align both ini and legacy to usec.
3. schedule_delayed_work receives the delay value in jiffies so
translate the dump delay to jiffies.

Subject: iwlwifi: mvm: fix the spatial reuse parsing for HE_TRIG PPDUs

The spatial reuse 4 words fields are fetched from the HE-SIGA
by the firmware and propagated to the driver through the
Rx info. This is useful to populate the radiotap header.

We were looking at the wrong place in the firmware data and
got bogus values. Fix that.

Subject: iwlwifi: dbg: buffer overflow in non_collect_ts_start array

The size of the buffer is IWL_FW_TRIGGER_ID_NUM - 1 which is equal to
IWL_FW_TRIGGER_ID_HOST_CHANNEL_SWITCH_COMPLETE so if the driver receives
this trigger, it will cause a buffer overflow.

Solve this by increasing the buffer size by 1.

Subject: iwlwifi: mvm: Don't warn on command failure during restart

When HW restart is requested but not started yet, commands would not
be sent to the FW, and some function calls return an error. Such cases
can trigger unneeded warning messages, e.g., in iwl_mvm_mac_sta_state()
and iwl_mvm_bss_info_changed_station().

Handle a couple of these cases by also checking in the WARN_ON()
condition that HW restart is not requested.

Subject: iwlwifi: mvm: stop static queues correctly

AP interfaces still use some static TX queues (for probes,
broadcast and multicast frames). These queues were not stopped
correctly when the transport layer indicated the queue should be
stopped. As a result, when flushing the queues, new frames from
the overflow queue were tx'd, so the queues still had frames after
flushing. This ended up in an assert since trying to remove a station
with non-empty queues.

Fix it by stopping the static queues correctly when required.

Subject: iwlwifi: fix false-positive maybe-uninitialized warning

With CONFIG_NO_AUTO_INLINE, we run into a silly warning when
gcc fails to remember that n_profiles is constant across
the function call to iwl_mvm_sar_set_profile:

drivers/net/wireless/intel/iwlwifi/mvm/fw.c: In function 'iwl_mvm_sar_get_ewrd_table':
drivers/net/wireless/intel/iwlwifi/mvm/fw.c:746:9: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Marking that function 'inline' avoids the warning.

Subject: iwlwifi: eeprom-parse: use struct_size() in kzalloc()

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 code was detected with the help of Coccinelle.

We support this, so we should advertise it. In fact, if we don't,
mac80211 will do it for us (as we advertise SUPPORTS_VHT_EXT_NSS_BW
to it), but that requires a memory reallocation which is wasteful:

  ieee80211 phy0: copying sband (band 1) due to VHT EXT NSS BW flag

Set the flag here to avoid that.

Subject: iwlwifi: fw: no need to check return value of debugfs_create
 functions

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Subject: iwlwifi: mvm: Allow retries for probe responses

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.

Subject: iwlwifi: mvm: implement VHT extended NSS support in rs.c

For non-offloaded rate control, implement VHT extended NSS
support by just ignoring 160 MHz on transmit if the peer
doesn't support the full NSS (2). This is pretty unlikely
and gets us 160 MHz RX as well as TX in most cases, since
the typical case for this workaround is 4x4 AP only doing
2x2 on 160 MHz.

Subject: iwlwifi: remove redundant condition from prior alive dump flow

After the FW image was loaded for the first time,
fwrt->smem_cfg.num_lmacs value will no longer be zero since we don't
clean it when we stop the device. So if we load the image once and then
we fail on a consecutive attempt, the driver will abort any dumping.

Solve this by removing the condition. It is safe to remove since
when we do the actual dumping in iwl_fw_dbg_collect_sync we check
that STATUS_DEVICE_ENABLED bit is still active.

The driver sets ignore_consec to -1 which is 0xffffffff in u32
so when iwl_fw_ini_trigger_on is called, it will always return false
and each trigger could be used only once.

Solve this by removing the assignment to -1.

Subject: iwlwifi: fix 64-bit division

do_div() expects unsigned operands and otherwise triggers a warning like:

drivers/net/wireless/intel/iwlwifi/mvm/ftm-initiator.c:465:2: error: comparison of distinct pointer types ('typeof ((rtt_avg)) *' (aka 'long long *') and 'uint64_t *' (aka 'unsigned long long *')) [-Werror,-Wcompare-distinct-pointer-types]
        do_div(rtt_avg, 6666);
        ^~~~~~~~~~~~~~~~~~~~~
include/asm-generic/div64.h:222:28: note: expanded from macro 'do_div'
        (void)(((typeof((n)) *)0) == ((uint64_t *)0));  \
               ~~~~~~~~~~~~~~~~~~ ^  ~~~~~~~~~~~~~~~
1 error generated.

Change the do_div() to the simpler div_s64() that can handle
negative inputs correctly.

Subject: iwlwifi: mvm: fix TX crypto on 22560+ devices

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.

Subject: iwlwifi: dbg_ini: in case of region dump failure set memory to 0

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.

Subject: iwlwifi: dbg_ini: fix bad dump size calculation

The driver initiates the size value with the size of the struct and then
adds the size of the data and checks if the size is zero so size can not
be equal to zero.

Solve this by getting the data size, check that it is not equal to zero
and only then add the struct size.

Subject: iwlwifi: use sync nmi in case of init flow failure

In case of alive interrupt timeout or any failure in the init flow
the driver generates FW nmi. The driver assumes that the nmi will
generate SW interrupt. This assumption does not hold and leads to faulty
behavior in the recovery flow.

Solve this by using sync nmi, this way, even if the driver does not
receive SW interrupt, it still starts the recovery flow.

Also remove the wait queue from iwl_fwrt_stop_device since the driver is
handling the SW interrupt synchronously.

Subject: iwlwifi: mvm: avoid possible deadlock in TX path

iwl_mvm_tx_mpdu() may run from iwl_mvm_add_new_dqa_stream_wk(), where
soft-IRQs aren't disabled. In this case, it may hold the station lock
and be interrupted by a soft-IRQ that also wants to acquire said lock,
leading to a deadlock.

Fix it by disabling soft-IRQs in iwl_mvm_add_new_dqa_stream_wk().

With offloaded rate control, if the station parameters (rates, NSS,

to propagate those change to the firmware.

Add a new configuration with a new firmware name for quz devices.
And, since these devices have the same PCI device and subsystem IDs,
we need to add some code to switch from a normal qu firmware to the
quz firmware.

Subject: iwlwifi: don't panic in error path on non-msix systems

The driver uses msix causes-register to handle both msix and non msix
interrupts when performing sync nmi.  On devices that do not support
msix this register is unmapped and accessing it causes a kernel panic.

Solve this by differentiating the two cases and accessing the proper
causes-register in each case.

Subject: iwlwifi: mvm: don't attempt debug collection in rfkill

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
level code to do things more carefully.

It's not 100% clear that it fixes this commit, as the original
dump code at the time might've been more careful. In any case,
we don't really need to dump anything in this expected scenario.

Subject: iwlwifi: dbg_ini: check debug TLV type explicitly

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.

Subject: iwlwifi: mvm: properly check debugfs dentry before using it

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 ff9fb72bc077 ("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.

Subject: iwlwifi: cfg: use family 22560 based_params for AX210 family

Specifically, max_tfd_queue_size should be 0x10000 like in
22560 family and not 0x100 like in 22000 family.

Subject: iwlwifi: mvm: check for length correctness in iwl_mvm_create_skb()

We don't check for the validity of the lengths in the packet received
from the firmware.  If the MPDU length received in the rx descriptor
is too short to contain the header length and the crypt length
together, we may end up trying to copy a negative number of bytes
(headlen - hdrlen < 0) which will underflow and cause us to try to
copy a huge amount of data.  This causes oopses such as this one:
