02f220b526 wifi: ipw2x00/lib80211: move remaining lib80211 into libipw
There's already much code in libipw that used to be shared
with more drivers, but now with the prior cleanups, those old
Intel ipw2x00 drivers are also the only ones using whatever is
now left of lib80211. Move lib80211 entirely into libipw.

57be3d3562 wifi: radiotap: Avoid -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct ieee80211_radiotap_header_fixed`.
This structure groups together all the members of the flexible
`struct ieee80211_radiotap_header` except the flexible array.

As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct ieee80211_radiotap_header` to `struct
ieee80211_radiotap_header_fixed`.

We also want to ensure that in case new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.

This approach avoids having to implement `struct ieee80211_radiotap_header_fixed`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.

So, with these changes, fix the following warnings:

07c90acb07 wifi: iwlegacy: Clear stale interrupts before resuming device
iwl4965 fails upon resume from hibernation on my laptop. The reason
seems to be a stale interrupt which isn't being cleared out before
interrupts are enabled. We end up with a race beween the resume
trying to bring things back up, and the restart work (queued form
the interrupt handler) trying to bring things down. Eventually
the whole thing blows up.

Fix the problem by clearing out any stale interrupts before
interrupts get enabled during resume.

Here's a debug log of the indicent:

cb787f4ac0 [tree-wide] finally take no_llseek out
no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")

To quote that commit,

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\<no_llseek\>/d' $i
  done

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

d4cdc46ca1 wifi: iwlegacy: Fix "field-spanning write" warning in il_enqueue_hcmd()
iwlegacy uses command buffers with a payload size of 320
bytes (default) or 4092 bytes (huge).  The struct il_device_cmd type
describes the default buffers and there is no separate type describing
the huge buffers.

The il_enqueue_hcmd() function works with both default and huge
buffers, and has a memcpy() to the buffer payload.  The size of
this copy may exceed 320 bytes when using a huge buffer, which
now results in a run-time warning:

    memcpy: detected field-spanning write (size 1014) of single field "&out_cmd->cmd.payload" at drivers/net/wireless/intel/iwlegacy/common.c:3170 (size 320)

To fix this:

- Define a new struct type for huge buffers, with a correctly sized
  payload field
- When using a huge buffer in il_enqueue_hcmd(), cast the command
  buffer pointer to that type when looking up the payload field

a032b5fc24 wifi: iwlwifi: mvm: properly set the rates in link cmd
When a channel ctx is assigned to a link, we set the
LINK_CONTEXT_MODIFY_RATES_INFO to indicate that the rate fields are now
valid. But then we always take the rates of 2.4 GHz regardless of actual
used band.
This is because we are getting the band from bss_conf->chanctx_conf, but
this is assigned only after drv_assign_vif_chanctx returns, so we take
the bands of 2.4 GHz.
Fix it by taking the band from the iwl_mvm_link_info::phy_ctxt instead,
as this has already assigned in this point.

07fb53783b wifi: iwlwifi: mvm: tell the firmware about CSA with mode=1
When we de-activate a link because it started a CSA with mode=1, we want
to tell the firmware it can no longer transmit any frame for that link.
The firmware will do that on its own if the CSA indication (beacon /
action frame) was  received on that same link, but with MLO, things got
more complex and the firmware can't track cross link CSA.

Tell the firmware if we de-activate a link because of CSA with mode=1 to
prevent it from transmitting, even if it is only an NDP PM=1 frame that
is part of the de-activation flow.

iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta

It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is
dereferencing the ieee80211_sta pointer.
If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL
pointer.
Fix this by checking the sta pointer before retrieving the mvmsta
from it. If sta is not NULL, then mvmsta isn't either.

1c7e1068a7 wifi: iwlwifi: mvm: drop wrong STA selection in TX
This shouldn't happen at all, since in station mode all MMPDUs
go through the TXQ for the STA, and not this function. There
may or may not be a race in mac80211 through which this might
happen for some frames while a station is being added, but in
that case we can also just drop the frame and pretend the STA
didn't exist yet.

Also, the code is simply wrong since it uses deflink, and it's
not easy to fix it since the mvmvif->ap_sta pointer cannot be
used without the mutex, and perhaps the right link might not
even be known.

Just drop the frame at that point instead of trying to fix it
up.

frames, and configures the RLC.

In this patch:
1. Stop sending RLC_CONFIG_CMD when firmware supports RLC
   offload (version 3), as rlc.rx_chain_info is not needed by
   firmware, and no other field in the cmd is used.
2. Prevent the driver from forwarding any SMPS requests to
   mac80211, i.e., the driver should not transmit SMPS frames
   to the AP as firmware handles that.
3. Set NL80211_FEATURE_DYNAMIC_SMPS and NL80211_FEATURE_STATIC_SMPS
   conditionally based on RLC version.

87c1c28a9a wifi: iwlwifi: mvm: Fix a race in scan abort flow
When the upper layer requests to cancel an ongoing scan, a race
is possible in which by the time the driver starts to handle the
upper layers scan cancel flow, the FW already completed handling
the scan request and the driver received the scan complete
notification but still did not handle the notification. In such a
case the FW will simply ignore the scan abort request coming from
the driver, no notification would arrive from the FW and the entire
abort flow would be considered a failure.

To better handle this, check the status code returned by the FW for
the scan abort command. In case the status indicates that
no scan was aborted, complete the scan abort flow with success, i.e.,
the scan was aborted, as the flow is expected to consume the scan
complete notification.

094513f8a2 wifi: iwlwifi: clear trans->state earlier upon error
When the firmware crashes, we first told the op_mode and only then,
changed the transport's state. This is a problem if the op_mode's
nic_error() handler needs to send a host command: it'll see that the
transport's state still reflects that the firmware is alive.

Today, this has no consequences since we set the STATUS_FW_ERROR bit and
that will prevent sending host commands. iwl_fw_dbg_stop_restart_recording
looks at this bit to know not to send a host command for example.

To fix the hibernation, we needed to reset the firmware without having
an error and checking STATUS_FW_ERROR to see whether the firmware is
alive will no longer hold, so this change is necessary as well.

Change the flow a bit.
Change trans->state before calling the op_mode's nic_error() method and
check trans->state instead of STATUS_FW_ERROR. This will keep the
current behavior of iwl_fw_dbg_stop_restart_recording upon firmware
error, and it'll allow us to call iwl_fw_dbg_stop_restart_recording
safely even if STATUS_FW_ERROR is clear, but yet, the firmware is not
alive.

An invalid buffer destination is not a problem for the driver and it
does not make sense to report it with the KERN_ERR message level. As
such, change the message to use IWL_DEBUG_FW.

cb347bd29d wifi: iwlwifi: mvm: fix hibernation
Fast resume is a feature that was recently introduced to speed up the
resume time. It basically keeps the firmware alive while the system
is suspended and that avoids starting again the whole device.

This flow can't work for hibernation, since when the system boots,
before the frozen image is loaded, the kernel may touch the device. As a
result, we can't assume the device is in the exact same state as before
the hibernation.

Detect that we are resuming from hibernation through the PCI device and
forbid the fast resume flow. We also need to shut down the device
cleanly when that happens.

In addition, in case the device is power gated during S3, we won't be
able to keep the device alive. Detect this situation with BE200 at least
with the help of the CSR_FUNC_SCRATCH register and reset the device upon
resume if it was power gated during S3.

a7e8997ae1 wifi: iwlegacy: Avoid multiple -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create new tagged structures with the suffix `_hdr`.
These structures group together all the members of the original
flexible structures except the flexible arrays.

As a result, the arrays are effectively separated from the rest of the
members without modifying the memory layout of the flexible structures.
We then change the type of the middle struct members currently causing
trouble from the original flex struct to the newly created structs with
suffix `_hdr`.

We also want to ensure that when new members need to be added to the
flexible structures, they are always included within the newly created
tagged structs. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.

This approach avoids having to implement the `_hdr` structures as
completely separate structures, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.

We also use `container_of()` whenever we need to retrieve a pointer to
the flexible structure, through which we can access the flexible-array
member, if necessary.

Also, remove a couple of unused zero-length arrays and flexible-array
members.

So, with these changes, fix the following warnings:

38c8d02501 wifi: iwlwifi: correctly lookup DMA address in SG table
The code to lookup the scatter gather table entry assumed that it was
possible to use sg_virt() in order to lookup the DMA address in a mapped
scatter gather table. However, this assumption is incorrect as the DMA
mapping code may merge multiple entries into one. In that case, the DMA
address space may have e.g. two consecutive pages which is correctly
represented by the scatter gather list entry, however the virtual
addresses for these two pages may differ and the relationship cannot be
resolved anymore.

Avoid this problem entirely by working with the offset into the mapped
area instead of using virtual addresses. With that we only use the DMA
length and DMA address from the scatter gather list entries. The
underlying DMA/IOMMU code is therefore free to merge two entries into
one even if the virtual addresses space for the area is not continuous.

e528be3c87 thermal: core: Allow thermal zones to tell the core to ignore them
The iwlwifi wireless driver registers a thermal zone that is only needed
when the network interface handled by it is up and it wants that thermal
zone to be effectively ignored by the core otherwise.

Before commit a8a2617744 ("thermal: core: Call monitor_thermal_zone()
if zone temperature is invalid") that could be achieved by returning
an error code from the thermal zone's .get_temp() callback because the
core did not really handle errors returned by it almost at all.
However, commit a8a2617744 made the core attempt to recover from the
situation in which the temperature of a thermal zone cannot be
determined due to errors returned by its .get_temp() and is always
invalid from the core's perspective.

That was done because there are thermal zones in which .get_temp()
returns errors to start with due to some difficulties related to the
initialization ordering, but then it will start to produce valid
temperature values at one point.

Unfortunately, the simple approach taken by commit a8a2617744,
which is to poll the thermal zone periodically until its .get_temp()
callback starts to return valid temperature values, is at odds with
the special thermal zone in iwlwifi in which .get_temp() may always
return an error because its network interface may always be down.  If
that happens, every attempt to invoke the thermal zone's .get_temp()
callback resulting in an error causes the thermal core to print a
dev_warn() message to the kernel log which is super-noisy.

To address this problem, make the core handle the case in which
.get_temp() returns 0, but the temperature value returned by it
is not actually valid, in a special way.  Namely, make the core
completely ignore the invalid temperature value coming from
.get_temp() in that case, which requires folding in
update_temperature() into its caller and a few related changes.

On the iwlwifi side, modify iwl_mvm_tzone_get_temp() to return 0
and put THERMAL_TEMP_INVALID into the temperature return memory
location instead of returning an error when the firmware is not
running or it is not of the right type.

Also, to clearly separate the handling of invalid temperature
values from the thermal zone initialization, introduce a special
THERMAL_TEMP_INIT value specifically for the latter purpose.

Linus Torvalds
51835949dd Networking changes for 6.11. Not much excitement - a handful of large
patchsets (devmem among them) did not make it in time.
 
 Core & protocols
 ----------------
 
  - Use local_lock in addition to local_bh_disable() to protect per-CPU
    resources in networking, a step closer for local_bh_disable() not
    to act as a big lock on PREEMPT_RT.
 
  - Use flex array for netdevice priv area, ensure its cache alignment.
 
  - Add a sysctl knob to allow user to specify a default rto_min at socket
    init time. Bit of a big hammer but multiple companies were
    independently carrying such patch downstream so clearly it's useful.
 
  - Support scheduling transmission of packets based on CLOCK_TAI.
 
  - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
    using cpusets.
 
  - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
 
  - Allow configuration of multipath hash seed, to both allow synchronizing
    hashing of two routers, and preventing partial accidental sync.
 
  - Improve TCP compliance with RFC 9293 for simultaneous connect().
 
  - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
    IKE daemon had to do this before, but the kernel can better keep
    track of it.
 
  - Support sending supervision HSR frames with MAC addresses stored in
    ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
 
  - Introduce IPPROTO_SMC for selecting SMC when socket is created.
 
  - Allow UDP GSO transmit from devices with no checksum offload.
 
  - openvswitch: add packet sampling via psample, separating the sampled
    traffic from "upcall" packets sent to user space for forwarding.
 
  - nf_tables: shrink memory consumption for transaction objects.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Power Sequencing subsystem (used by Qualcomm Bluetooth driver
    for QCA6390).
 
  - Add IRQ information in sysfs for auxiliary bus.
 
  - Introduce guard definition for local_lock.
 
  - Add aligned flavor of __cacheline_group_{begin, end}() markings for
    grouping fields in structures.
 
 BPF
 ---
 
  - Notify user space (via epoll) when a struct_ops object is getting
    detached/unregistered.
 
  - Add new kfuncs for a generic, open-coded bits iterator.
 
  - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
    bpf_list_head.
 
  - Support resilient split BTF which cuts down on duplication and makes
    BTF as compact as possible WRT BTF from modules.
 
  - Add support for dumping kfunc prototypes from BTF which enables both
    detecting as well as dumping compilable prototypes for kfuncs.
 
  - riscv64 BPF JIT improvements in particular to add 12-argument support
    for BPF trampolines and to utilize bpf_prog_pack for the latter.
 
  - Add the capability to offload the netfilter flowtable in XDP layer
    through kfuncs.
 
 Driver API
 ----------
 
  - Allow users to configure IRQ tresholds between which automatic IRQ
    moderation can choose.
 
  - Expand Power Sourcing (PoE) status with power, class and failure
    reason. Support setting power limits.
 
  - Track additional RSS contexts in the core, make sure configuration
    changes don't break them.
 
  - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
    data paths.
 
  - Support updating firmware on SFP modules.
 
 Tests and tooling
 -----------------
 
  - mptcp: use net/lib.sh to manage netns.
 
  - TCP-AO and TCP-MD5: replace debug prints used by tests with
    tracepoints.
 
  - openvswitch: make test self-contained (don't depend on OvS CLI tools).

   - Add a sysctl knob to allow user to specify a default rto_min at
     socket init time. Bit of a big hammer but multiple companies were
     independently carrying such patch downstream so clearly it's useful

   - Support scheduling transmission of packets based on CLOCK_TAI

   - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
     off using cpusets

   - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address

   - Allow configuration of multipath hash seed, to both allow
     synchronizing hashing of two routers, and preventing partial
     accidental sync

   - Improve TCP compliance with RFC 9293 for simultaneous connect()

   - Support sending NAT keepalives in IPsec ESP in UDP states.
     Userspace IKE daemon had to do this before, but the kernel can
     better keep track of it

   - Support sending supervision HSR frames with MAC addresses stored in
     ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled

   - Introduce IPPROTO_SMC for selecting SMC when socket is created

   - Allow UDP GSO transmit from devices with no checksum offload

   - openvswitch: add packet sampling via psample, separating the
     sampled traffic from "upcall" packets sent to user space for
     forwarding

   - nf_tables: shrink memory consumption for transaction objects

  Things we sprinkled into general kernel code:

   - Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
     QCA6390)           [ Already merged separately - Linus ]

   - Introduce guard definition for local_lock

   - Add aligned flavor of __cacheline_group_{begin, end}() markings for
     grouping fields in structures

     detached/unregistered

   - Add new kfuncs for a generic, open-coded bits iterator

   - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
     bpf_list_head

   - Support resilient split BTF which cuts down on duplication and
     makes BTF as compact as possible WRT BTF from modules

   - Add support for dumping kfunc prototypes from BTF which enables
     both detecting as well as dumping compilable prototypes for kfuncs

   - riscv64 BPF JIT improvements in particular to add 12-argument
     support for BPF trampolines and to utilize bpf_prog_pack for the
     latter

   - Add the capability to offload the netfilter flowtable in XDP layer
     through kfuncs

  Driver API:

   - Allow users to configure IRQ tresholds between which automatic IRQ
     moderation can choose

   - Expand Power Sourcing (PoE) status with power, class and failure
     reason. Support setting power limits

     changes don't break them

   - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
     ESP data paths

0728c81087 thermal: trip: Pass trip pointer to .set_trip_temp() thermal zone callback
Out of several drivers implementing the .set_trip_temp() thermal zone
operation, three don't actually use the trip ID argument passed to it,
two call __thermal_zone_get_trip() to get a struct thermal_trip
corresponding to the given trip ID, and the other use the trip ID as an
index into their own data structures with the assumption that it will
always match the ordering of entries in the trips table passed to the
core during thermal zone registration, which is fragile and not really
guaranteed.

Even though the trip IDs used by the core are in fact their indices in the
trips table passed to it by the thermal zone creator, that is purely a
matter of convenience and should not be relied on for correctness.

For this reason, modify trip_point_temp_store() to pass a (const) trip
pointer to .set_trip_temp() and adjust the drivers implementing it
accordingly.

This helps to simplify the drivers invoking __thermal_zone_get_trip()
from their .set_trip_temp() callback functions because they will not
need to do it now and the other drivers can store their internal
trip indices in the priv field in struct thermal_trip and their
.set_trip_temp() callback functions can get those indices from there.

The intel_quark_dts thermal driver can instead use the trip type to
determine the requisite trip index.

changes both in stack and in drivers. The big thing is the multiple
radios for wiphy feature which makes it possible to better advertise
radio capabilities to user space. mt76 enabled MLO and iwlwifi
re-enabled MLO, ath12k and rtw89 Wi-Fi 6 devices got WoWLAN support.

a2ed933dfe wifi: iwlwifi: release TXQ lock during reclaim
Much of the work during reclaim can be done without holding the TXQ
lock and releasing the lock means that command submission can happen at
the same time.

while working with an internal copy of the txq->read_ptr and only take
the lock again when updating the read pointer after the cleanup is done.

1a3364e963 wifi: iwlwifi: keep BHs disabled when TXing from reclaim
During reclaim, we may release the txq->lock spinlock in order to call
iwl_trans_tx to queue new frames. The iwl_trans_tx function expects to
be called with BHs disabled and iwl_pcie_reclaim is most of the times
called with BHs disabled already. However, reclaim can also happen after
flushing a STA and in that case BHs will not be disabled.

Solve this corner case by only releasing the spinlock but keeping BHs
disabled.

The entries[] array needs to be cacheline aligned to avoid false
sharing between different queues, each queue has a set of entries
in it that it writes to.

While it is aligned in practice today given that each array entry
before it is aligned, it's still clearer to explicitly require it

8c62617295 wifi: mac80211: remove DEAUTH_NEED_MGD_TX_PREP
This flag is annoying because it puts a lot of logic into mac80211
that could just as well be in the driver (only iwlmvm uses it) and
the implementation is also broken for MLO.

Remove the flag in favour of calling drv_mgd_prepare_tx() without
any conditions even for the deauth-while-assoc case. The drivers
that implement it can take the appropriate actions, which for the
only user of DEAUTH_NEED_MGD_TX_PREP (iwlmvm) is a bit more tricky
than the implementation in mac80211 is anyway, and all others have
no need and can just exit if info->was_assoc is set.

When UATS isn't enabled (no VLP/AFC AP support), we need to still

Also, firmware deals just fine with getting the UATS table if it

it, since it's also needed if BIT(31) is set, but the driver need
not have any knowledge of that. Remove 'uats_enabled' entirely.

3591e3b9a7 wifi: iwlwifi: mei: clarify iwl_mei_pldr_req() docs
This isn't related to whether or not "fw can be loaded",
but rather requesting that ME go into a state where doing
a product reset is safe. This is related to FW load only
in the specific case of where it's used today in iwlmvm,
notably when it's known that the firmware itself will (or
at least may) do a product reset during load.

Clarify the documentation.

I was tempted to rename things too, but on the ME side it
really is also called PLDR (which is a Windows term and
may not even match the complete behaviour since doing a
full product reset from the driver also requires calling
an ACPI method first.) So keep the name aligned with ME.

67c638675d wifi: iwlwifi: mvm: rename 'pldr_sync'
PLDR (product level device reset) is a Windows term, and
is something the driver triggers there, AFAICT.

Really what 'pldr_sync' here wants to capture is whether
or not the firmware will/may do a product reset during
initialization, which makes the device drop off the bus,
requiring a rescan. If this is the case, obviously the
init will fail/time out, so we don't want to report all
kinds of errors etc., hence this tracking variable.

Rename it to 'fw_product_reset' to capture the meaning
better.

AP interfaces fundamentally cannot leave the channel, so multi-
channel operation with them isn't really possible. We shouldn't
advertise support for such, at least not as long as we don't
have full multi-radio support. Thus, remove the AP bit from the
interface combinations for two channels and add another set for
just one channel that has it.

Also, to avoid duplicating everything even more, unify the NAN
and non-NAN cases.

bd40215b19 wifi: iwlwifi: mvm: fix re-enabling EMLSR
When EMLSR gets unblocked, the current code checks if the last exit was
due to an EXIT reason (as opposed to a BLOCKING one), and if so, it
does nothing, as in this case a MLO scan was scheduled to run in 30
seconds.

But the code doesn't consider the time that passed from the last exit,
so if immediately after the exit a blocker occurred (e.g. non-BSS
interface), and lasts for more than 30 seconds, then the MLO scan and the
following link selection will decide not to enter EMLSR, and when the
unblocking event finally happens, the reason is still set to the EXIT one,
so it will do nothing, and we will not have the chance to re-enable EMLSR.

Fix this by checking also the time that has passed since the last exit,
only if it is less than 30 seconds, we can count on the scheduled MLO
scan.

Note that clearing the reason itself can't be done since it is needed
for the EMLSR prevention mechanism.

49101078be wifi: iwlwifi: pcie: integrate TX queue code
The TX queue code was mostly moved out to support an internal
transport that we were never going to publish, but we're no
longer using that. Since we're also going to be dissolving
the virtual transport layer entirely, integrate the TX queue
code into the PCIe layer.

This also has a small kernel of already removing the virtual
transport function layer, since iwl_trans_send_cmd() calls
iwl_trans_pcie_send_hcmd() directly now, even if that still
calls the transport send_cmd method for now, we'll clean it
up later.

Also, not everything is renamed yet.

e6dd2936ce wifi: iwlwifi: mvm: Fix scan abort handling with HW rfkill
When HW rfkill is toggled to disable the RF, the flow to stop scan is
called. When trying to send the command to abort the scan, since
HW rfkill is toggled, the command is not sent due to rfkill being
asserted, and -ERFKILL is returned from iwl_trans_send_cmd(), but this
is silently ignored in iwl_mvm_send_cmd() and thus the scan abort flow
continues to wait for scan complete notification and fails. Since it
fails, the UID to type mapping is not cleared, and thus a warning is
later fired when trying to stop the interface.

To fix this, modify the UMAC scan abort flow to force sending the
scan abort command even when in rfkill, so stop the FW from accessing
the radio etc.

When entering RF-kill, mac80211 tears down BA sessions, but
due to RF-kill the commands aren't sent to the device. As a
result, there can be frames pending on the reorder buffer or

Avoid the warnings by doing the BA session teardown normally

cc3ba78f20 wifi: iwlwifi: mvm: remove stale STA link data during restart
If pre-recovery mac80211 tried to disable a link but this disablement
failed, then there might be a mismatch between mac80211 assuming the
link has been disabled and the driver still having the data around.
During recover itself, that is not a problem, but should the link be
activated again at a later point, iwlwifi will refuse the activation as
it detects the inconsistent state.

Solve this corner-case by iterating the station in the restart cleanup
handler.

32fca7e382 wifi: iwlwifi: dvm: clean up rs_get_rate() logic
The logic here is rather convoluted - we cannot get here with
lq_sta being NULL as mac80211 will (no longer) call us like
that, and since I removed the rate_control_send_low() call in
this function there's no longer any point in setting priv_sta
to NULL either.

So the only thing that remains to check is if we have actually
initialized our lq_sta->drv pointer, and exit if we didn't in
which case we'll use the data mac80211 already set up for the
low rate usage.

2c92ca849f tracing/treewide: Remove second parameter of __assign_str()
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.

This means that with:

  __string(field, mystring)

Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.

There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:

  git grep -l __assign_str | while read a ; do
      sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
      mv /tmp/test-file $a;
  done

I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.

Note, the same updates will need to be done for:

  __assign_str_len()
  __assign_rel_str()
  __assign_rel_str_len()

I tested this with both an allmodconfig and an allyesconfig (build only for both).

b1992c3772 kbuild: use $(src) instead of $(srctree)/$(src) for source directory
Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:

    src := $(obj)

When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.

This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.

To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.

Going forward, the variables used in Makefiles will have the following
meanings:

  $(obj)     - directory in the object tree
  $(src)     - directory in the source tree  (changed by this commit)
  $(objtree) - the top of the kernel object tree
  $(srctree) - the top of the kernel source tree

Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

2e194efa38 wifi: iwlwifi: mvm: Fix race in scan completion
The move of the scan complete notification handling to the wiphy worker
introduced a race between scan complete notification and scan abort:

- The wiphy lock is held, e.g., for rfkill handling etc.
- Scan complete notification is received but not handled yet.
- Scan abort is triggered, and scan abort is sent to the FW. Once the
  scan abort command is sent successfully, the flow synchronously waits
  for the scan complete notification. However, as the scan complete
  notification was already received but not processed yet, this hangs for
  a second and continues leaving the scan status in an inconsistent
  state.
- Once scan complete handling is started (when the wiphy lock is not held)
  since the scan status is not an inconsistent state, a warning is issued
  and the scan complete notification is not handled.

To fix this issue, switch back the scan complete notification to be
asynchronously handling, and only move the link selection logic to
a worker (which was the original reason for the move to use wiphy lock).

While at it, refactor some prints to improve debug data.

a1efeb8230 wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is active
When there's an active link in a non-station vif, the station vif is
not allowed to enter EMLSR

Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule
an exit from EMLSR worker, but the worker cannot run before the
activation of the non-BSS link, as ieee80211_remain_on_channel already
holds the wiphy mutex.

Handle that by explicitly calling ieee80211_set_active_links()
to leave EMLSR, and then doing iwl_mvm_block_esr() only for
consistency and to avoid re-entering it before ready.

Note that a call to ieee80211_set_active_links requires to release the
mvm mutex, but that's ok since we still hold the wiphy lock. The only
thing that might race here is the ESR_MODE_NOTIF, so this changes its
handler to run under the wiphy lock.

The new link selection algorithm uses defaults values for BSS load if
the BSS Load element was not published by the AP.
For 6 GHz, that value is 0. So if the best link is 6 GHz, the EMLSR

and then the best link grade is getting a bonus of 10 percent, meaning
that we will never activate EMLSR.

72c19df24a wifi: iwlwifi: cleanup EMLSR when BT is active handling
BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the
vif from using EMLSR with a different link pair. In addition, storing it
in mvmvif:disable_esr_reason requires extracting the BT Coex bit before
checking if EMLSR is blocked or not for a specific vif.

Therefore, change the BT Coex bit to be an exit reason and not a
blocker. On link selection, EMLSR mode will be re-calculated for the 2.4
GHz link instead of checking that bit.

While at it, move the relevant function declarations to the EMLSR
functions area in mvm.h

b73c138a87 wifi: iwlwifi: pcie: allocate dummy net_device dynamically
struct net_device shouldn't be embedded into any structure, instead,
the owner should use the priv space to embed their state into net_device.

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_device from struct iwl_trans_pcie by converting it
into a pointer. Then use the leverage alloc_netdev() to allocate the
net_device object at iwl_trans_pcie_alloc.

The private data of net_device becomes a pointer for the struct
iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent
given the net_device object.
