ee1a02d760 iwlmvm: set properly NIC_NOT_ACK_ENABLED flag
The STA_CTXT_HE_NIC_NOT_ACK_ENABLED flag tells the firmware
whether *we* support ack-enabled.
So what should be checked is our *own* capability and not
the *peer's* capability.

9ce505feb1 iwlwifi: mvm: Check ret code for iwl_mvm_load_nvm_to_nic
Return value of the iwl_mvm_load_nvm_to_nic func is not analyzed. If load
NVM to nic func fails and NVM is not loaded to fw properly, then fw may
behave badly and lead to some strange issue. This commit will analyze
return value and if load NVM to nic has failed, then the error code is
sent to the previous func, which will trigger WRT log collection.
iwl_fw_dbg_error_collect() func collects dump only if tri type is
FW_DBG_TRIGGER_ALIVE_TIMEOUT. But when Load NVM to nic function fails
trig_type is FW_DBG_TRIGGER_DRIVER. This commit also has code changes to
collect dump when trig_type is FW_DBG_TRIGGER_DRIVER.

8c082a99ed iwlwifi: mvm: simplify iwl_mvm_dbgfs_register
No need to pass the dbgfs_dir just to assign it to mvm.
Assign to mvm and then call iwl_mvm_dbgfs_register.

This is a preparation towards the addition of a delayed
op_mode_start flow.
This will allow to split the op_mode_start flow.
Registration to debugfs must happen after we register to
mac80211 and the registration to mac80211 will soon be
delayed in certain cases. In order not to have to remember
the debugfs_dir in a separate variable, just set it into
the mvm structure so that it can be usable later.

Declare mvm->debugfs_dir in the iwl_mvm structure even when
IWLWIFI_DEBUGFS isn't enabled to simplify the source code.

21254908cb iwlwifi: mvm: add RFI-M support
RF Interference Mitigation is a new feature targeted to handle the
problem of interference between DDR memory and WiFi. The role of
the driver is to configure FW with the table holding a mapping
between problematic channels/bands and the corresponding frequencies.

This patch adds RFI infrastructure and adds two debugfs hooks:
- send RFI configuration command (currently with a default table) which
  will reset feature in the FW
- read the table, used by the FW (which can be a subset of the table
  that driver sent).

iwl_mvm_sar_geo_init() function, after the table revision is assigned

5a6842455c iwlwifi: mvm: fix the type we use in the PPAG table validity checks
The value we receive from ACPI is a long long unsigned integer but the
values should be treated as signed char.  When comparing the received
value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison,
so the negative value would actually be treated as a very high number.

To solve this issue, assign the value to our table of s8's before
making the comparison, so the value is already converted when we do
so.

that occur while we can still access the fw and collect debug data.

When we check the length, we only check that the advertised

that it actually matches correctly.

This should be harmless, but if the first two bytes are zero,
then the iwl_rx_packet_payload_len() ends up negative, and
that might later cause issues if unsigned variables are used,
as this is not something that's normally expected.

708a39aaca iwlwifi: mvm: don't send commands during suspend\resume transition
D3_CONFIG_CMD and D0I3_END_CMD should be the last\first
command upon suspend\resume correspondingly, otherwise,
FW will raise an assert (0x342).

There are firmware notifications that cause the driver to
send a command back to the firmware. If such a notification
is sent to the driver while the the driver prepares the
firmware for D3, operation, what is likely to happen is that
the handling of the notification will try to get the mutex
and will wait unil the driver finished configuring the
firmware for D3. Then the handling notification will get
the mutex and handle the notification which will lead to
the aforementioned ASSERT 342.

To avoid this, we need to prevent any command to be sent to
the firmware between the D3_CONFIG_CMD and the D0I3_END_CMD.
Check this in the utility layer that sends the host commands
and in the transport layer as well.
Flag the D3_CONFIG_CMD and the D0I3_END_CMD commands as
commands that must be sent even if the firmware has already
been configured for D3 operation.

We shouldn't trust the firmware with the sizes (or contents)

Add a general framework for checking a minimum size of any

a05829a722 cfg80211: avoid holding the RTNL when calling the driver
Currently, _everything_ in cfg80211 holds the RTNL, and if you
have a slow USB device (or a few) you can get some bad lock
contention on that.

Fix that by re-adding a mutex to each wiphy/rdev as we had at
some point, so we have locking for the wireless_dev lists and
all the other things in there, and also so that drivers still
don't have to worry too much about it (they still won't get
parallel calls for a single device).

Then, we can restrict the RTNL to a few cases where we add or
remove interfaces and really need the added protection. Some
of the global list management still also uses the RTNL, since
we need to have it anyway for netdev management, but we only
hold the RTNL for very short periods of time here.

96d2bfb794 iwlwifi: mvm: clear IN_D3 after wowlan status cmd
In D3 resume flow, avoid the following race where sending
packets before updating the sequence number (sequence
number received from the wowlan status command response):
Thread 1:
__iwl_mvm_resume clears IWL_MVM_STATUS_IN_D3 and is cut
by thread 2 before reaching iwl_mvm_query_wakeup_reasons.
Thread 2:
iwl_mvm_mac_itxq_xmit calls iwl_mvm_tx_skb since
IWL_MVM_STATUS_IN_D3 is not set using a wrong sequence number.
Thread 1:
__iwl_mvm_resume continues and calls iwl_mvm_query_wakeup_reasons
updating the sequence number received from the firmware.

The next packet that will be sent now will cause sysassert 0x1096.

Fix the bug by moving 'clear IWL_MVM_STATUS_IN_D3' to after
sending the wowlan status command and updating the sequence
number.

Having sta_id not set for aux_sta and snif_sta can potentially lead to a

this case sta_id 0, an unrelated regular station, will be removed.

In fact, we do have a FW assert that occures rarely and from the debug

hard to pinpoint the exact flow. The WARN_ON in this patch should help

caf4637712 iwlwifi: mvm: fix a race in CSA that caused assert 0x3420
When we get a channel switch with a very long quiet period, we schedule
a work to disconnect after a while. This work runs in background. In the
meanwhile, we keep getting beacons and sending FW modify command for each.
This has a potential race, where we modify the CSA after we aborted it.

Protect the flow by setting csa_failed to true in case we abort, and check
it before sending the modify command.

This required a modification to the way we treat csa_failed in
iwl_mvm_post_channel_switch:
1. The variable isn't being reset anymore, so we can still look at it in
iwl_mvm_channel_switch_rx_beacon. This is fine, since we reset it when
starting a new CSA.
2. There is no more early return in case of csa_failed. This is fine,
since before this patch csa_failed was set only for GO, and for GO the
function is only resetting the power settings, which we want to restore
even in case of failure.

doesn't really clearly say what it's counting.

During CSA, we briefly nullify the phy context, in __iwl_mvm_unassign_vif_chanctx.
In case we have a FW assert right after it, it remains NULL though.
We end up running into endless loop due to mac80211 trying repeatedly to

we hit a kernel panic.

45acebf8d6 iwlwifi: fix sar geo table initialization
When adding support for version 3 of the GEO_TX_POWER_LIMIT command,
the table argument of iwl_sar_geo_init was changed from a pointer a 1d
array of now-removed iwl_per_chain_offset_group_v1 to a pointer to a 2d
array of iwl_per_chain_offset (iwl_per_chain_offset_group_v1 was a
struct containing 2 copies of iwl_per_chain_offset).

So even for version 2 where the second dimension is of length 2, which
means that the underlying memory layout of the array didn't change, this
requires a small change in the way we loop over it, and this was missed.

Additionally, for the case of version 3 where the second dimension is now
3, in order to fill the first two elements of each row correctly (lb and
hb), iwl_sar_geo_init must get the true number of bands supported.
But because we don't yet store any values for the 3rd (uhb) band, skip
that band.

The scan request may specify the request scan dwell time.
However, this value may not always be optimal (e.g. short dwell
time for a passive channel). This may happen in a scan request
as a result of beacon report request, in which the AP may request
an active scan, thus setting a short dwell time, but the station
will perform a passive scan due to regulatory.

Ignore the scan duration parameter and always use the internal

b68bd2e314 iwlwifi: mvm: Add FTM initiator RTT smoothing logic
The overcome instabilities in the RTT results add smoothing logic
to the reported results. In short, the smoothing logic tracks the
RTT average of each responder for a period of time, and in case
a new RTT results is found to be a spur, the tracked RTT average
is reported instead of the current RTT measurement.

Smooth logic debug configuration using iwl-dbg-cfg.ini:

- MVM_FTM_INITIATOR_ENABLE_SMOOTH: Set to 1 to enable smoothing logic
 (default=0).
- MVM_FTM_INITIATOR_SMOOTH_ALPHA: A value between 0 - 100, defining
  the weight of the current RTT results vs. the RTT average tracked
  based on the previous results. A value of 100 means use only the
  current RTT results.
- MVM_FTM_INITIATOR_SMOOTH_AGE_SEC: The maximal time in seconds in which
  the RTT average tracked based on previous results is considered valid.
- MVM_FTM_INITIATOR_SMOOTH_UNDERSHOOT: if the current RTT is positive
  and below the RTT average by at least this value, report the average
  RTT instead of the current one. In units of picoseconds.
- MVM_FTM_INITIATOR_SMOOTH_OVERSHOOT: if the current RTT is positive
  and above the RTT average by at least this value, report the average
  RTT instead of the current one. In units of picoseconds.

2b3eb12234 iwlwifi: mvm: process ba-notifications also when sta rcu is invalid
The the driver prevents new Tx from being sent during the remove-station
flow is by invalidating the fw_id_to_mac_id rcu of that station.

However, if there was any Tx still in-flight (tx-cmd was sent but the
ba-notif wasn't received yet) the ba-response to those frames is simply
ignored without actually reclaiming anything. This later causes the
driver to think that that some of the station's queues aren't empty when
in practice they are which causes errors in the station remove flow.

Fix this by performing the tx-reclaim also if the rcu is invalid. any DB
that can't be updated due to this is not very important at this stage
since the station is about to be removed soon anyways.

a57066b1a0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
The UDP reuseport conflict was a little bit tricky.

The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.

At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.

This requires moving the reuseport_has_conns() logic into the callers.

While we are here, get rid of inline directives as they do not belong
in foo.c files.

The other changes were cases of more straightforward overlapping
modifications.

For ACK_ENABLED and 32BIT_BA_BITMAP flags check the station capabilities
rather than bss_conf.ack_enabled and bss_conf.multi_sta_back_32bit.
These fields are stations capabilities and should not be in bss_conf.
Also note that the bss_conf flags are set in station mode only.
In the next patch I will remove ack_enabled and multi_sta_back_32bit
from the bss_conf structure.

a65a582429 iwlwifi: avoid debug max amsdu config overwriting itself
If we set amsdu_len one after another the second one overwrites
the orig_amsdu_len so allow only moving from debug to non debug state.

Also the TLC update check was wrong: it was checking that also the orig
is smaller then the new updated size, which is not the case in debug
amsdu mode.

Mode notification.

Implement it by
 * parsing the 160/80+80 bit there and setting the bandwidth
   appropriately
 * having callers of ieee80211_get_vht_max_nss() pass in the current
   max NSS value as received in the operating mode notification in
   order to modify it appropriately depending on the extended NSS
   bits.

This updates all drivers that use it, i.e. only iwlwifi/mvm.

6cb5f3ea46 mac80211: populate debugfs only after cfg80211 init
When fixing the initialization race, we neglected to account for
the fact that debugfs is initialized in wiphy_register(), and
some debugfs things went missing (or rather were rerooted to the
global debugfs root).

Fix this by adding debugfs entries only after wiphy_register().
This requires some changes in the rate control code since it
currently adds debugfs at alloc time, which can no longer be
done after the reordering.

1edd56e69d iwlwifi: fix WGDS check when WRDS is disabled
In the reference BIOS implementation, WRDS can be disabled without
disabling WGDS.  And this happens in most cases where WRDS is
disabled, causing the WGDS without WRDS check and issue an error.

To avoid this issue, we change the check so that we only considered it
an error if the WRDS entry doesn't exist.  If the entry (or the
selected profile is disabled for any other reason), we just silently
ignore WGDS.

e5b72e3bc4 iwlwifi: mvm: limit maximum queue appropriately
Due to some hardware issues, queue 31 isn't usable on devices that have
32 queues (7000, 8000, 9000 families), which is correctly reflected in
the configuration and TX queue initialization.

However, the firmware API and queue allocation code assumes that there
are 32 queues, and if something actually attempts to use #31 this leads
to a NULL-pointer dereference since it's not allocated.

Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also
add some code to catch this earlier in the future, if the configuration
changes perhaps.

22f33971aa wireless-drivers-next patches for v5.7
Third set of patches for v5.7. Nothing really special this time,
 business as usual.
 
 When pulling this to net-next there's again a conflict in:
 
 drivers/net/wireless/intel/iwlwifi/pcie/drv.c
 
 To solve this drop these three lines from the conflict (the first hunk
 from "HEAD") as the whole AX200 block was moved above in the same
 file:
 
 	IWL_DEV_INFO(0x2723, 0x1653, iwl_ax200_cfg_cc, iwl_ax200_killer_1650w_name),
 	IWL_DEV_INFO(0x2723, 0x1654, iwl_ax200_cfg_cc, iwl_ax200_killer_1650x_name),
 	IWL_DEV_INFO(0x2723, IWL_CFG_ANY, iwl_ax200_cfg_cc, iwl_ax200_name),
 
 And keep all the __IWL_DEV_INFO() entries (the second hunk). In other
 words, take everything from wireless-drivers-next. When running 'git
 diff' after the resolution the output should be empty.
 
 Major changes:
 
 brcmfmac
 
 * add USB autosuspend support
 
 ath11k
 
 * handle RX fragments
 
 * enable PN offload
 
 * add support for HE BSS color
 
 iwlwifi

 * support for EDCA measurements
 
 * new scan API features

Kalle gave me directions on how to resolve the iwlwifi conflict
as follows:

====================
When pulling this to net-next there's again a conflict in:

drivers/net/wireless/intel/iwlwifi/pcie/drv.c

To solve this drop these three lines from the conflict (the first hunk
from "HEAD") as the whole AX200 block was moved above in the same
file:

	IWL_DEV_INFO(0x2723, 0x1653, iwl_ax200_cfg_cc, iwl_ax200_killer_1650w_name),

095650c054 iwlwifi: add support for version 2 of SOC_CONFIGURATION_CMD
This new command is mostly backwards compatible, with the exception
that the device_type element was changed into a bitmask.  The device
type bit remains the same (because we only had 0 and 1 anyway), but
when using v1 we can't set any other bits, because that would change
the integer.

Other than that, the struct remains the same and the driver can set
the device_type bit in both cases, but it can only set the low_latency
bit if VER_2 is used.

7897dfa2bc iwlwifi: move integrated, extra_phy and soc_latency to trans_cfg
These values are selected based on the PCI device ID, so the decision
to use them can be made early.  By moving them to the trans_cfg, we
avoid duplicating the large cfg structs for small pieces of
data (sometimes a single boolean).  This will also allow us to make
more decisions based on, for instance, the SoC type in used.

The trans_cfg concept changes a bit, because previously it was used
only to boot the device before reading further characteristics and now
it also contains more data that is associated with the device ID.

a9149d243f iwlwifi: mvm: Do not require PHY_SKU NVM section for 3168 devices
The logic for checking required NVM sections was recently fixed in
commit b3f20e0982 ("iwlwifi: mvm: fix NVM check for 3168
devices"). However, with that fixed the else is now taken for 3168
devices and within the else clause there is a mandatory check for the
PHY_SKU section. This causes the parsing to fail for 3168 devices.

The PHY_SKU section is really only mandatory for the IWL_NVM_EXT
layout (the phy_sku parameter of iwl_parse_nvm_data is only used when
the NVM type is IWL_NVM_EXT). So this changes the PHY_SKU section
check so that it's only mandatory for IWL_NVM_EXT.

cc4255eff5 iwlwifi: mvm: avoid use after free for pmsr request
When a FTM request is aborted, the driver sends the abort command to
the fw and waits for a response. When the response arrives, the driver
calls cfg80211_pmsr_complete() for that request.
However, cfg80211 frees the requested data immediately after sending
the abort command, so this may lead to use after free.

Fix it by clearing the request data in the driver when the abort
command arrives and ignoring the fw notification that will come
afterwards.

Till now, the driver asked the fw for a DTS measurement in automatic
mode. This triggered a flow in which the fw actively measured the
temperature.  This is not needed anymore, as the fw performs
measurements by itself, without the driver triggering them, and the
current cadence in which the fw performs such measurements is
sufficient.

In addition, in some time-sensitive scenarios, in which the driver asks
the fw for an active measurement twice in a short time (<100ms), the fw
asserts with code 0x20100801.

Change the DTS measurement to _WITHOUT_MEASURE instead, so the fw will
respond with the last measurement it has performed.

197288d5ba iwlwifi: don't throw error when trying to remove IGTK
The IGTK keys are only removed by mac80211 after it has already
removed the AP station.  This causes the driver to throw an error
because mac80211 is trying to remove the IGTK when the station doesn't
exist anymore.

The firmware is aware that the station has been removed and can deal
with it the next time we try to add an IGTK for a station, so we
shouldn't try to remove the key if the station ID is
IWL_MVM_INVALID_STA.  Do this by removing the check for mvm_sta before
calling iwl_mvm_send_sta_igtk() and check return from that function
gracefully if the station ID is invalid.

d829229e35 iwlwifi: mvm: don't send the IWL_MVM_RXQ_NSSN_SYNC notif to Rx queues
The purpose of this was to keep all the queues updated with
the Rx sequence numbers because unlikely yet possible
situations where queues can't understand if a specific
packet needs to be dropped or not.

Unfortunately, it was reported that this caused issues in
our DMA engine. We don't fully understand how this is related,
but this is being currently debugged. For now, just don't send
this notification to the Rx queues. This de-facto reverts my
commit 3c514bf831:

iwlwifi: mvm: add a loose synchronization of the NSSN across Rx queues

This issue was reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=204873
https://bugzilla.kernel.org/show_bug.cgi?id=205001
and others maybe.

It is now possible to propagate BSS color settings into the subsystem. Lets

205608749e Revert "iwlwifi: mvm: fix scan config command size"
Since v5.4-rc1 was released, iwlwifi started throwing errors when scan
commands were sent to the firmware with certain devices (depending on
the OTP burned in the device, which contains the list of available
channels).  For instance:

iwlwifi 0000:00:14.3: FW error in SYNC CMD SCAN_CFG_CMD

This bug was reported in the ArchLinux bug tracker:
https://bugs.archlinux.org/task/64703

And also in a specific case in bugzilla, when the lar_disabled option
was set: https://bugzilla.kernel.org/show_bug.cgi?id=205193

Revert the commit that introduced this error, by using the number of
channels from the OTP instead of the number of channels that is
specified in the FW TLV that tells us how many channels it supports.

This reverts commit 06eb547c4a.

f06021a18f iwlwifi: remove lar_disable module parameter
This is an old parameter that was used supposed to be used only when
LAR was still under development.  It should not be used anymore, but,
since it's available, end-users have been mangling with it
unnecessarily.  In some cases it can cause problems because when LAR
is supported the driver and the firmware do not expect it to be
disabled.

b9f726c942 iwlwifi: mvm: fix SKB leak on invalid queue
It used to be the case that if we got here, we wouldn't warn
but instead allocate the queue (DQA). With using the mac80211
TXQs model this changed, and we really have nothing to do with
the frame here anymore, hence the warning now.

However, clearly we missed in coding & review that this is now
a pure error path and leaks the SKB if we return 0 instead of
an indication that the SKB needs to be freed. Fix this.

ed780545c1 iwlwifi: mvm: report TX rate to mac80211 directly for RS offload
If we have offloaded rate scaling, which is always true for those
devices supporting HE, then report the TX rate directly from the
data the firmware gives us, instead of only passing it to mac80211
on frame status only and for it to track it.

First of all, this makes us always report the last good rate that
the rate scaling algorithm picked, which is better than reporting
the last rate for any frame since management frames etc. are sent
with very low rates and could interfere.

Additionally, this allows us to properly report HE rates, though
in case there's a lot of trigger-based traffic, we don't get any
choice in the rates and don't report that properly right now.

b3f20e0982 iwlwifi: mvm: fix NVM check for 3168 devices
We had a check on !NVM_EXT and then a check for NVM_SDP in the else
block of this if.  The else block, obviously, could only be reached if
using NVM_EXT, so it would never be NVM_SDP.

Fix that by checking whether the nvm_type is IWL_NVM instead of
checking for !IWL_NVM_EXT to solve this issue.

a89c72ffd0 iwlwifi: pcie: allocate smaller dev_cmd for TX headers
As noted in the previous commit, due to the way we allocate the
dev_cmd headers with 324 byte size, and 4/8 byte alignment, the
part we use of them (bytes 20..40-68) could still cross a page
and thus 2^32 boundary.

Address this by using alignment to ensure that the allocation
cannot cross a page boundary, on hardware that's affected. To
make that not cause more memory consumption, reduce the size of
the allocations to the necessary size - we go from 324 bytes in
each allocation to 60/68 on gen2 depending on family, and ~120
or so on gen1 (so on gen1 it's a pure reduction in size, since
we don't need alignment there).

To avoid size and clearing issues, add a new structure that's
just the header, and use kmem_cache_zalloc().

This fixes a long-standing bug - we haven't been able to check the
firmware image that was loaded for D3/not-D3 since the introduction
of the unified image...

Fix this by keeping a status flag for D3 instead of checking for
the firmware image that's loaded.

This reduces occurrences of checks for IWL_UCODE_WOWLAN to just the
code that actually loads the image or deals with it in other ways.
