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().

If there's any vendor-specific element in the subelements
then the outer element parsing must not parse any vendor
element at all. This isn't implemented correctly now due
to parsing into the pointers and then overriding them, so
explicitly skip vendor elements if any exist in the sub-
elements (non-transmitted profile or per-STA profile).

The code is erroneously applying the non-inheritance element
to the inner elements rather than the outer, which is clearly
completely wrong. Fix it by finding the MLE basic element at
the beginning, and then applying the non-inheritance for the
outer parsing.
While at it, do some general cleanups such as not allowing
callers to try looking for a specific non-transmitted BSS
and link at the same time.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and debugfs updates from Greg KH:
"Here is the big set of driver core and debugfs updates for 6.14-rc1.
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 rust 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.

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

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.

ieee80211_determine_chan_mode is called for each link and if there is a
downgrade, then it is interesting to know on which link it happened.
Pass through the link_id where relevant and use the new link_id_info
macro instead of sdata_info so that the link ID is printed when
relevant.

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.

Sometimes we might want to flush only part of the stations of a vif,
for example only the TDLS ones.
To allow this, add a do_not_flush_sta argument to __sta_info_flush,
which in turn, will not flush this station.

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.

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.
