Instead of differentiating only sync/async, differentiate
the type of error, and document that only reset handshake
timeout (IWL_ERR_TYPE_RESET_HS_TIMEOUT) needs sync handling.
The special sync handling is somewhat temporary, the idea
is to later split the nic_error() method into error dump,
synchronizing the dump, and SW reset methods, and the type
is mostly in order to unify command queue full handling
into that new architecture as well.

We only logged an error in the fast resume path. However, as the

easier to understand what is happening.

Currently, the sequence goes like this (among others):
1. flush all stations (including the AP ones) -> this will tell the
drivers to remove the stations
2. notify the driver the vif is not associated.
Which means that in between 1 and 2, the state is that the vif is
associated, but there is no AP station, which makes no sense, and may be
problematic for some drivers (for example iwlwifi)
Change the sequence to:
1. flush the TDLS stations
2. move the AP station to IEEE80211_STA_NONE
3. notify the driver about the vif being unassociated
4. flush the AP station
In order to not break other drivers, add a vif flag to indicate whether
the driver wants to new sequence or not. If the flag is not set, then
things will be done in the old sequence.

in iwl_mvm_sta_del we call iwl_mvm_sec_key_remove_ap with link id 0,
when it might actually be something else, causing us to skip all
the keys.
Since the call to iwl_mvm_sec_key_remove_ap was mostly skipped (because
for STA mode we are not removing the ap sta immediately, but later when
the vif is set to unassocicated),
this was fine.
The other call to iwl_mvm_sec_key_remove_ap, when we actually do remove the
ap sta, was called with the right link id. So the bug didn't happen so far.
Now that mac80211 is going to change such that we can immediately
remove the ap sta, the call to iwl_mvm_sec_key_remove_ap with link id 0
will not be skipped, so no key will be removed, and then when
mac80211 eventually tells us to remove that keys, we no longer have the
sta ids for them.
Simply pass the right link id to iwl_mvm_sec_key_remove_ap.

Both struct cfg80211_wowlan_nd_match and struct cfg80211_wowlan_nd_info
pre-allocate space for channels and matches, but then may end up using
fewer that the full allocation. Shrink the associated counter
(n_channels and n_matches) after counting the results. This avoids
compile-time (and run-time) warnings from __counted_by. (The counter
member needs to be updated _before_ accessing the array index.)

If we got an unprotected action frame with CSA and then we heard the
beacon with the CSA IE, we'll block the queues with the CSA reason
twice. Since this reason is refcounted, we won't wake up the queues
since we wake them up only once and the ref count will never reach 0.
This led to blocked queues that prevented any activity (even
disconnection wouldn't reset the queue state and the only way to recover
would be to reload the kernel module.
Fix this by not refcounting the CSA reason.
It becomes now pointless to maintain the csa_blocked_queues state.
Remove it.

Since we no longer shut down the device in suspend, we also no longer
call iwl_mvm_mei_device_state() and this is a problem because iwlmei
expects this to be called when it runs its own suspend sequence. It
checks mei->device_down in iwl_mei_remove() which is called upon
suspend.
Fix this by telling iwlmei when we're done accessing the device.
When we'll wake up, the device should be untouched if CSME didn't use it
during the suspend time. If CSME used it, we'll notice it through the
CSR_FUNC_SCRATCH register.

If more than 255 colocated APs exist for the set of all
APs found during 2.4/5 GHz scanning, then the 6 GHz scan
construction will loop forever since the loop variable
has type u8, which can never reach the number found when
that's bigger than 255, and is stored in a u32 variable.
Also move it into the loops to have a smaller scope.
Using a u32 there is fine, we limit the number of APs in
the scan list and each has a limit on the number of RNR
entries due to the frame size. With a limit of 1000 scan
results, a frame size upper bound of 4096 (really it's
more like ~2300) and a TBTT entry size of at least 11,
we get an upper bound for the number of ~372k, well in
the bounds of a u32.

When we add the vif (and its default link) in fw restart we may
override the link that already exists. We take care of this but if
link 0 is a valid MLO link, then we will re-create a default link on
mvmvif->link[0] and we'll loose the real link we had there.
In non-MLO, we need to re-create the default link upon the interface
creation, this is fine. In MLO, we'll just wait for change_vif_links()
to re-build the links.

The current flow in _ieee80211_set_active_links() does not align with the
operational requirements of drivers that groups multiple hardware
under a single wiphy. These drivers (e.g ath12k) rely on channel
assignment to determine the appropriate hardware for each link. Without
this, the drivers cannot correctly establish the link interface.
Currently in _ieee80211_set_active_links(), after calling
drv_change_vif_links() on the driver, the state of all connected stations
is updated via drv_change_sta_links(). This is followed by handling keys
in the links, and finally, assigning the channel to the links.
Consequently, drv_change_sta_links() prompts drivers to create the station
entry at their level and within their firmware. However, since channels
have not yet been assigned to links at this stage, drivers have not
created the necessary link interface for establishing link stations,
leading to failures in activating the links.
Therefore, re-order the logic so that after drv_change_vif_links() and
removing the old links, channels are assigned to newly added links.
Following this, the flow proceeds to station handling.

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.

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

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.

Currently, the driver handles SMPS decisions by tracking AP
capabilities, BT coexistence changes, sending necessary SMPS
frames to the AP, and updating firmware with RX chain info
using the RLC_CONFIG_CMD.
Starting with version 3 of the RLC_CONFIG_CMD, the firmware
takes over this responsibility. It now tracks SMPS, sends
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.

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.

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.

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.

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).

Pull networking updates from Jakub Kicinski:
"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) [ Already merged separately - Linus ]
- 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)

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.

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

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.

Really what 'pldr_sync' here wants to capture is whether
or not the firmware will/may do a product reset during

requiring a rescan. If this is the case, obviously the
init will fail/time out, so we don't want to report all

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

just one channel that has it.

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.

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
perhaps even received while doing so, leading to warnings.
Avoid the warnings by doing the BA session teardown normally
even in RF-kill, which also requires queue sync.

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

already know the frame wasn't received well, e.g. has bad PLCP.
Unless the firmware reports "no error", set the bad PLCP flag
to skip checks in mac80211.
Also, since we're now extracting two different values from the
info field, use le32_get_bits() for both.

fw_running assumes that memory can be retrieved only after alive.
This assumption is no longer true as we support dump before alive.
To avoid invalid access to the NIC, check that STATUS_DEVICE_ENABLED
bit in trans status is set before dumping instead of the prior check.

Add an entry for setting the maximum TXOP time in microseconds.
The configured value can be read from the same entry.
