When userspace sets supported rates for a new station via
NL80211_CMD_NEW_STATION, it might send a list that's empty
or contains only invalid values. Currently, we process these
values in sta_link_apply_parameters() without checking the result of
ieee80211_parse_bitrates(), which can lead to an empty rates bitmap.
A similar issue was addressed for NL80211_CMD_SET_BSS in commit
ce04abc3fc ("wifi: mac80211: check basic rates validity").
This patch applies the same approach in sta_link_apply_parameters()
for NL80211_CMD_NEW_STATION, ensuring there is at least one valid
rate by inspecting the result of ieee80211_parse_bitrates().
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

We first want to flush the station to make sure we no longer have any
frames being Tx by the station before the station is moved to
un-authorized state. Failing to do that will lead to races: a frame may
be sent after the station's state has been changed.
Since the API clearly states that the driver can't fail the sta_state()
transition down the list of state, we can easily flush the station
first, and only then call the driver's sta_state().

then the outer element parsing must not parse any vendor

to parsing into the pointers and then overriding them, so
explicitly skip vendor elements if any exist in the sub-

When we disassociate we may need to send a deauth frame.
Regardless of this decision, we need to flush the queues to drop all the
packets on the Tx queues.
The flow looks like this:
1) Flush packets waiting on the queues (drop=true)
2) Prepare Tx to send the deauth
3) Build the deauth header
4) send the deauth
5) Flush the deauth packet (drop=false)
6) Complete_tx
Step 3 and 4 are done in ieee80211_send_deauth_disassoc() and that
function must be called even if we decide not to send the deauth
frame because we need step 3 for cfg80211.
This means that if we want to send the deauth frame, we need all the
steps, but if we don't want to send the deauth frame we still want step
1 and 3.
Change the code to do that.
Also, prevent sending the deauth frame if we are in the middle of a CSA
with mode=1 in which case we won't be able to send the frame anyway.
This caused issues in iwlwifi at step 5 since the firmware wouldn't
send the frame and we'd be stuck flushing with drop=false.
Implement this in ieee80211_set_disassoc() which has many callers.

Here is the big set of driver core and debugfs updates for 6.14-rc1.
It's coming late in the merge cycle as there are a number of merge
conflicts with your tree now, and I wanted to make sure they were
working properly. To resolve them, look in linux-next, and I will send
the "fixup" patch as a response to the pull request.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at least
one user that does have a regression with these, but Al is working on
tracking down the fix for it. In my use (and everyone else's linux-next
use), it does not seem like a big issue at the moment.
Here's a short list of the things in here:
- driver core bindings for PCI, platform, OF, and some i/o functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing things
in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon".

Existing primitive has several problems:
1) calling conventions are clumsy - it returns a dentry reference
that is either identical to its second argument or is an ERR_PTR(-E...);
in both cases no refcount changes happen. Inconvenient for users and
bug-prone; it would be better to have it return 0 on success and -E... on
failure.
2) it allows cross-directory moves; however, no such caller have
ever materialized and considering the way debugfs is used, it's unlikely
to happen in the future. What's more, any such caller would have fun
issues to deal with wrt interplay with recursive removal. It also makes
the calling conventions clumsier...
3) tautological rename fails; the callers have no race-free way
to deal with that.
4) new name must have been formed by the caller; quite a few
callers have it done by sprintf/kasprintf/etc., ending up with considerable
boilerplate.
Proposed replacement: int debugfs_change_name(dentry, fmt, ...). All callers
convert to that easily, and it's simpler internally.
IMO debugfs_rename() should go; if we ever get a real-world use case for
cross-directory moves in debugfs, we can always look into the right way
to handle that.

In case of authentication/association timeout (as detected in
ieee80211_iface_work->ieee80211_sta_work), ieee80211_destroy_auth_data
is called.
At the beginning of it, the pointer to ifmgd::auth_data memory is
copied to a local variable.
If iface_work is queued again during the execution of the current one,
and then the driver is flushing the wiphy_works (for its needs),
ieee80211_destroy_auth_data will run again and free auth_data.
Then when the execution of the original worker continues, the previously
copied pointer will be freed, causing a kernel bug:
kernel BUG at mm/slub.c:553! (double free)
Same for association timeout (just with ieee80211_destroy_assoc_data and
ifmgd::assoc_data)
Fix this by NULLifying auth/assoc data right after we copied
the pointer to it. That way, even in the scenario above, the code will
not handle the same timeout twice.

Add support for adding and removing station links:
- Adding links is done asynchronously, i.e., first
an ML reconfiguration action frame is sent to the AP
requesting to add links, and only when the AP replies,
links which were added successfully by the AP are added
locally.
- Removing links is done synchronously, i.e., the links
are removed before sending the ML reconfiguration
action frame to the AP (to avoid using this links after
the AP MLD removed them but before the station got the
ML reconfiguration response). In case the AP replies with a
status indicating that a link removal was not successful,
disconnect (as this should not happen an is an indication
that something might be wrong on the AP MLD).

With change (wifi: mac80211: fix receiving A-MSDU
frames on mesh interfaces), a non-zero TID assignment
is lost during slow path mesh forwarding.
Prior to this change, ieee80211_rx_h_mesh_fwding()
left the TID intact in the header.
As a result of this header corruption, packets belonging
to non-zero TIDs will get treating as belonging
TID 0 by functions such as ieee80211_get_tid().
While this miscategorization by itself is an
issue, there are additional ramifications
due to the fact that skb->priority still reflects
the mesh forwarded packet's ingress (correct) TID.
The mt7915 driver inspects the TID recorded within
skb->priority and relays this to the
hardware/radio during TX. The radio firmware appears to
react to this by changing the sequence control
header, but it does not also ensure/correct the TID in
the QoS control header. As a result, the receiver
will see packets with sequence numbers corresponding
to the wrong TID. The receiver of the forwarded
packet will see TID 0 in QoS control but a sequence number
corresponding to the correct (different) TID in sequence
control. This causes data stalls for TID 0 until
the TID 0 sequence number advances past what the receiver
believes it should be due to this bug.
Mesh routing mpath changes cause a brief transition
from fast path forwarding to slow path forwarding.
Since this bug only affects the slow path forwarding,
mpath changes bring opportunity for the bug to be triggered.
In the author's case, he was experiencing TID 0 data stalls
after mpath changes on an intermediate mesh node.
These observed stalls may be specific
to mediatek radios. But the inconsistency between
the packet header and skb->priority may cause problems
for other drivers as well. Regardless if this causes
connectivity issues on other radios, this change is
necessary in order transmit (forward) the packet on the
correct TID and to have a consistent view a packet's TID
within mac80211.

In order to save power, it can be desirable to change the
RX operating mode using OMI to reduce the bandwidth. As the
handshake must be done in the HTC+ field, it cannot be done
by mac80211 directly, so expose functions to the driver to
request and finalize the necessary updates.
Note that RX OMI really only changes what the peer (AP) will
transmit to us, but in order to use it to actually save some
power (by reducing the listen bandwidth) we also update rate
scaling and then the channel context's mindef accordingly.
The updates are split into two in order to sequence them
correctly, when reducing bandwidth first reduce the rate
scaling and thus TX, then send OMI, then reduce the listen
bandwidth (chandef); when increasing bandwidth this is the
other way around. This also requires tracking in different
variables which part is applicable already.

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.

Currently, ieee80211_ie_build_he_oper() lacks support for 320 MHz handling
(already noted as a TODO). This is because 320 MHz is not included in
IEEE 802.11-ax. However, IEEE 802.11-be introduces 320 MHz support and if
the chandef indicates a 320 MHz bandwidth and is used directly as it is, it
will result in an incorrect HE Operation Information Element.
In order to support EHT 320 MHz, HE Operation Element should indicate
bandwidth as 160 MHz only. In EHT Operation IE, the correct bandwidth will
be present. Devices capable of EHT can parse EHT Information Element and
connect in 320 MHz and other HE capable devices can parse HE and can
connect in 160 MHz.
Add support to downgrade the bandwidth in ieee80211_ie_build_he_oper()
during 320 MHz operation and advertise it.

ML interfaces can have multiple affiliated links to it and
hence there is a need to report tx power of specified link
rather deflink.
Add changes to report tx power of requested link from mac80211,
also pass link id as an argument in get_tx_power op so that supported
drivers can use it to report link's tx power.

Currently, TX power is reported on interface/wdev level as
part of NL80211_CMD_GET_INTERFACE. With MLO, Multiple links
can be part of an interface/wdev and hence its necessary to
report the TX power of each link.
Add support to send tx power for all valid links of an MLD as
part of NL80211_CMD_GET_INTERFACE request.
As far as userspace is concerned, there is no behavioral change
for Non-ML Interfaces. For ML interfaces, userspace should fetch
TX power that is nested inside NL80211_ATTR_MLO_LINKS, similar to
how channel info(NL80211_ATTR_WIPHY_FREQ) is fetched.

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.

Currently, during link deletion, the link ID is first removed from the
valid_links bitmap before performing any clean-up operations. However, some
functions require the link ID to remain in the valid_links bitmap. One
such example is cfg80211_cac_event(). The flow is -
nl80211_remove_link()
cfg80211_remove_link()
ieee80211_del_intf_link()
ieee80211_vif_set_links()
ieee80211_vif_update_links()
ieee80211_link_stop()
cfg80211_cac_event()
cfg80211_cac_event() requires link ID to be present but it is cleared
already in cfg80211_remove_link(). Ultimately, WARN_ON() is hit.
Therefore, clear the link ID from the bitmap only after completing the link
clean-up.

On 32-bit systems, the size of an unsigned long is 4 bytes,
while a u64 is 8 bytes. Therefore, when using
or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE),
the code is incorrectly searching for a bit in a 32-bit
variable that is expected to be 64 bits in size,
leading to incorrect bit finding.
Solution: Ensure that the size of the bits variable is correctly
adjusted for each architecture.

Move the `struct ieee80211_chanctx_conf conf` to the end of
`struct ieee80211_chanctx` and fix a memory corruption bug
triggered e.g. in `hwsim_set_chanctx_magic()`: `radar_detected`
is being overwritten when `cp->magic = HWSIM_CHANCTX_MAGIC;`
See the function call sequence below:
drv_add_chanctx(... struct ieee80211_chanctx *ctx) ->
local->ops->add_chanctx(&local->hw, &ctx->conf) ->
mac80211_hwsim_add_chanctx(... struct ieee80211_chanctx_conf *ctx) ->
hwsim_set_chanctx_magic(ctx)
This also happens in a number of other drivers.
Also, add a code comment to try to prevent people from introducing
new members after `struct ieee80211_chanctx_conf conf`. Notice that
`struct ieee80211_chanctx_conf` is a flexible structure --a structure
that contains a flexible-array member, so it should always be at
the end of any other containing structures.
This change also fixes 50 of the following warnings:

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.

In order to deal with (temporary) bandwidth reductions to/from
the AP such as the upcoming RX OMI changes, modify the min_def
calculation to also not take the chanreq width into account in
client mode. This normally changes nothing as the AP bandwidth
will be the same as the channel request's width. In the RX OMI
changes, however, the code will reduce the bandwidth for only
the AP STA, since the OMI is only to that, and TDLS STAs are
unaffected. Using the min_def for this case simplifies RX OMI
a lot.

Andrei previously fixed an issue in the client where the NSS
for links other than the primary/assoc/deflink isn't set. The
same issue appears to exist on the AP side, because there's
only a call to rate_control_rate_init() for the deflink, and
not any other links.
Rework the code a bit to do rate_control_rate_init() for links,
even if it really doesn't work with software rate control yet,
it does other things as well.
Also add rate_control_rate_init_all_links() to actually do it
properly when moving to ASSOC state in cfg80211.
Change the explicit call to ieee80211_sta_init_nss() to instead
be rate_control_rate_init() now in the client code, but also
add a call to rate_control_rate_init() when a link is added in
AP mode and the STA is already associated.
This should fix the NSS initialization issue, and perhaps pave
the way for actual software rate scaling a bit, in case anyone
cares in the future, but that of course needs a lot more than
just the init call.
We still need to fix the rate control _update_ as well, and the
sta_rc_update() driver method especially, but that will be in a
different patch.

Drivers may need to track this. Make it available for them, and maintain
the value when beacons are received.
When link X receives a beacon, iterate the RNR elements and update all
the links with their respective data.
Track the link id that updated the data so that each link can know
whether the update came from its own beacon or from another link.
In case, the update came from the link's own beacon, always update the
updater link id.
The purpose is to let the low level driver know if a link is losing its
beacons. If link X is losing its beacons, it can still track the
bss_param_ch_cnt and know where the update came from.

In practice, userspace hasn't been able to set this for many
years, and mac80211 has already rejected it (which is now no
longer needed), so reject SMPS mode (other than "OFF" to be
a bit more compatible) in AP mode. Also remove the parameter
from the AP settings struct.

The wiphy lock cannot be taken directly from color collision detection
delayed work (ieee80211_color_collision_detection_work()) because this
work is cancel_delayed_work_sync() under this wiphy lock causing a
potential deadlock( see [0] for details).
To fix that ieee80211_color_collision_detection_work() could be
converted to a wiphy work and cancel_delayed_work_sync() can be simply
replaced by wiphy_delayed_work_cancel() serving the same purpose under
wiphy lock.
This could potentially fix [1].

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,

Currently DFS works under assumption there could be only one channel
context in the hardware. Hence, drivers just calls the function
ieee80211_radar_detected() passing the hardware structure. However, with
MLO, this obviously will not work since number of channel contexts will be
more than one and hence drivers would need to pass the channel information
as well on which the radar is detected.
Also, when radar is detected in one of the links, other link's CAC should
not be cancelled.
Hence, in order to support DFS with MLO, do the following changes -
* Add channel context conf pointer as an argument to the function
ieee80211_radar_detected(). During MLO, drivers would have to pass on
which channel context conf radar is detected. Otherwise, drivers could
just pass NULL.
* ieee80211_radar_detected() will iterate over all channel contexts
present and
* if channel context conf is passed, only mark that as radar
detected
* if NULL is passed, then mark all channel contexts as radar
detected
* Then as usual, schedule the radar detected work.
* In the worker, go over all the contexts again and for all such context
which is marked with radar detected, cancel the ongoing CAC by calling
ieee80211_dfs_cac_cancel() and then notify cfg80211 via
cfg80211_radar_event().
* To cancel the CAC, pass the channel context as well where radar is
detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is
canceled only on the links using the provided context, leaving other
links unaffected.
This would also help in scenarios where there is split phy 5 GHz radio,
which is capable of DFS channels in both lower and upper band. In this
case, simultaneous radars can be detected.

Currently, during starting a radar detection, no link id information is
parsed and passed down. In order to support starting radar detection
during Multi Link Operation, it is required to pass link id as well.
Add changes to first parse and then pass link id in the start radar
detection path.
Additionally, update notification APIs to allow drivers/mac80211 to
pass the link ID.
However, everything is handled at link 0 only until all API's are ready to
handle it per link.

A few members related to DFS handling are currently under per wireless
device data structure. However, in order to support DFS with MLO, there is
a need to have them on a per-link manner.
Hence, as a preliminary step, move members cac_started, cac_start_time
and cac_time_ms to be on a per-link basis.
Since currently, link ID is not known at all places, use default value of
0 for now.
