The modern way to disable bands is ieee80211-freq-limit, which is

This array is fully initialized in the loop itself. No need to zero
initialize and then overwrite.
Remove static from the array. This was a holdover from when the array
was a static global variable. It no longer confers any benefit.
Also add a min() call to avoid the manual if/ternary operation.

Clear ath9k DMA descriptors with explicit status word stores instead of
memset(). The descriptor rings are coherent DMA memory, which may be
mapped uncached on 32-bit powerpc. The optimized memset() path can use
dcbz there and trigger an alignment warning.
Use WRITE_ONCE() for the descriptor status words so the compiler keeps
the clears as ordinary stores instead of folding them back into bulk
memset(). This covers AR9003 TX status descriptors as well as the RX
status area cleared when setting up RX descriptors.

The firmware response length is only checked against sizeof(*rsp) (20
bytes), but when candidate_cnt >= 1, a 22-byte candidate struct is read
at buf + 20 without verifying the response contains it. This causes an

Commit d594cc6f2c ("wifi: mac80211: restore non-chanctx injection
behaviour") restored the monitor injection fallback for drivers using
chanctx emulation but explicitly deferred drivers that transitioned
to real chanctx ops. mt76 falls in that category and still drops
every injected frame when monitor coexists with another interface.
When the monitor has no chanctx of its own, fall back to the only
chanctx in flight if there is exactly one. Refuse if multiple are
present: picking arbitrarily would inject on an unrelated channel.
Emulated and real chanctx drivers both flow through this fallback,
since emulation always presents zero or one chanctx in
local->chanctx_list.
Reran the airgeddon evil-twin flow (hostapd AP + coexisting monitor
VIF on the same phy + aireplay-ng deauth from the monitor) on
mt7921e PCIe and mt7921u USB across 2.4 GHz and 5 GHz, and on a
Kali VM with MT7921U passthrough as the closest match to the
original reporter's setup. None reproduced the hang seen against
the earlier attempt at this fix
(<20251216111909.25076-2-johannes@sipsolutions.net>) or against v1
on lore in March.

Our binding handling for P2P-Device can run into the following
scenario, as observed by our testing:
- a station interface is connected on some channel
- the P2P-Device does a remain-on-channel (ROC) on that channel
- the ROC ends, and the P2P-Device is removed from the binding,
but the phy_ctxt pointer is left around as a PHY cache so we
don't need to recalibrate to the channel again and again in
case it's not shared
- a binding update by the station interface, even a removal,
will re-add the P2P-Device to the binding
- the P2P-Device is removed, which removes the PHY context, but
it's still in the binding so the firmware crashes
Since the P2P device is removed from the binding and only re-
added by unrelated code, but we want to keep the phy_ctxt around
as a cache for future ROC usage, fix it by adding a boolean that
indicates whether or not the P2P-Device should be added to the
binding, and handle that in the binding iterator. That way, the
station interface cannot re-add the P2P-Device to the binding
when that isn't active.

Clearly, from a user perspective, it must be valid to configure
WoWLAN and then suspend while not connected to a network. Since
mac80211 doesn't distinguish these cases and simply calls the
driver to suspend whenever WoWLAN is configured, the driver has
to cleanly handle the case where it's called for WoWLAN, it's
not connected but there's also no netdetect configured.
Remove the WARN_ON() and keep returning 1 to disconnect and
then suspend.

Currently, the dump code attempts to dump any number of
memories and register banks, as defined by the firmware.
Especially when the device is failing, this can lead to
excessive time spent attempting to acquire NIC access
over and over again.
Improve the code to only attempt to acquire NIC access
once or twice, but using the new memory dump functions
that may drop the spinlock etc. Mark all dump regions
that require NIC access, and skip them if we couldn't
obtain that.
In order to avoid CPU latency due to the increased time
holding the spinlock (and possibly disabling softirqs),
drop locks and call cond_resched() after each section
(if holding NIC access) but don't release HW NIC access.

There's similar code in two places in HT and HE, and we need to add
the same again for UHR. Rename ieee80211_link_sta_rc_update_omi()
to ieee80211_link_sta_update_rc_bw() and move it to sta_info.c and
update existing code that can use it to do so.

UHR requires MLO, not just formally but also in order
for the client to understand AP BSS parameter changes,
since the Critical Update Counter is inside the Multi-
Link Element. Require MLO for UHR connections to avoid
otherwise needed complexity such as not enabling any
feature that would require tracking critical updates.

During beacon processing, the parser is always called with
a BSS to find the correct multi-BSSID profile (if any) and
therefore never attempts to parse a multi-link element.
This means the code to handle cross-link CSA can effectively
never do anything.
Fix this by parsing the multi-link element in the regular
parser as well.
