d7074be64a wifi: mac80211: move CSA finalize to wiphy work
This work should be made per link as well, and then
will have cancellation issues. Moving it to a wiphy
work already fixes those beforehand.

This also has the wiphy locked here then. We need to use
the _locked version of cfg80211_sched_scan_stopped() now,
which also fixes an old deadlock there.

730538edc8 wifi: mac80211: lock wiphy in IP address notifier
Lock the wiphy in the IP address notifier as another
place that should have it locked before calling into
the driver. This needs a bit of attention since the
notifier can be called while the wiphy is already
locked, when we remove an interface. Handle this by
not running the notifier in this case, and instead
calling out to the driver directly.

It might seem that we could run these concurrently for

0ab6cba069 wifi: mac80211: hold wiphy lock in netdev/link debugfs
It's no longer really needed to ensure that the debugfs
file isn't going away, debugfs handles that. So there's
no point in holding dev_base_lock or RTNL here, but we
should instead hold the wiphy lock since drivers will
be allowed to depend on that. Do that, which requires
splitting the sdata and link macros a bit.

Since we no longer really use the RTNL, there's no point
in locking it here. Most drivers don't really need to
have any locks here anyway, and the rest are probably
completely broken, but it's a debugfs-only callback so
it really doesn't matter much.

e3640a82e5 wifi: mac80211: fix SMPS status handling
The current SMPS status handling isn't per link, so we only
ever change the deflink, which is obviously wrong, it's not
even used for multi-link connections, but the request API
actually includes the link ID.

Use the new status_data changes to move the handling to the
right link, this also saves parsing the frame again on the
status report, instead we can now check only if it was an
SMPS frame.

Of course, move the worker to be a wiphy work so that we're
able to cancel it safely for the link.

e665ab9c5a wifi: mac80211: Fix SMPS handling in the context of MLO
When the connection is a MLO connection, a SMPS request should be
sent on a specific link, as SMPS is BSS specific, and the DA and BSSID
used for the action frame transmission should be the AP MLD address, as
the underlying driver is expected to perform the address translation
(based on the link ID).

Fix the SMPS request handling to use the AP MLD address and provide the
link ID for the request processing during Tx.

b98c16107c wifi: mac80211: limit reorder_buf_filtered to avoid UBSAN warning
The commit 06470f7468 ("mac80211: add API to allow filtering frames in BA sessions")
added reorder_buf_filtered to mark frames filtered by firmware, and it
can only work correctly if hw.max_rx_aggregation_subframes <= 64 since
it stores the bitmap in a u64 variable.

However, new HE or EHT devices can support BlockAck number up to 256 or
1024, and then using a higher subframe index leads UBSAN warning:

 UBSAN: shift-out-of-bounds in net/mac80211/rx.c:1129:39

capability is not suitable.

Due to all the multi-link handling, we now expose the fact that
the sdata/vif is locked to drivers, e.g. when the driver uses
ieee80211_set_monitor_channel(). This was true when a chanctx
is added to or removed from a link, _except_ in monitor mode
with the virtual sdata/vif. Change that, so that drivers can

92bf4dd358 wifi: mac80211: agg-tx: prevent start/stop race
There were crashes reported in this code, and the timer_shutdown()
warning in one of the previous patches indicates that the timeout
timer for the AP response (addba_resp_timer) is still armed while
we're stopping the aggregation session.

After a very long deliberation of the code, so far the only way I
could find that might cause this would be the following sequence:
 - session start requested
 - session start indicated to driver, but driver returns
   IEEE80211_AMPDU_TX_START_DELAY_ADDBA
 - session stop requested, sets HT_AGG_STATE_WANT_STOP
 - session stop worker runs ___ieee80211_stop_tx_ba_session(),
   sets HT_AGG_STATE_STOPPING

From here on, the order doesn't matter exactly, but:

 1. driver calls ieee80211_start_tx_ba_cb_irqsafe(),
    setting HT_AGG_STATE_START_CB
 2. driver calls ieee80211_stop_tx_ba_cb_irqsafe(),
    setting HT_AGG_STATE_STOP_CB
 3. the worker will run ieee80211_start_tx_ba_cb() for
    HT_AGG_STATE_START_CB
 4. the worker will run ieee80211_stop_tx_ba_cb() for
    HT_AGG_STATE_STOP_CB

(the order could also be 1./3./2./4.)

This will cause ieee80211_start_tx_ba_cb() to send out the AddBA
request frame to the AP and arm the timer, but we're already in
the middle of stopping and so the ieee80211_stop_tx_ba_cb() will
no longer assume it needs to stop anything.

Prevent this by checking for WANT_STOP/STOPPING in the start CB,
and warn if we're sending a frame on a stopping session.
