+Subject: [PATCH] headers: fix lockdep_assert_not_held()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+LOCK_STATE_HELD define was omitted during backport of
+lockdep_assert_not_held() which leads to build failures of kernels with
+CONFIG_LOCKDEP=y:
+
+ backports-5.15.8-1/backport-include/linux/lockdep.h:16:47: error: 'LOCK_STATE_HELD' undeclared (first use in this function)
+
+Fix it by adding missing LOCK_STATE_HELD define.

+Subject: [PATCH] mac80211: sta: randomize BA session dialog token allocator
+
+We currently always start the dialog token generator at zero,
+so the first dialog token we use is always 1. This would be
+OK if we had a perfect guarantee that we always do a proper
+deauth/re-auth handshake, but in IBSS mode this doesn't always
+happen properly.
+
+To make problems with block ack (aggregation) sessions getting
+stuck less likely, randomize the dialog token so if we start a
+new session but the peer still has old state for us, it can
+better detect this.
+
+This is really just a workaround to make things a bit more
+robust than they are now - a better fix would be to do a full
+authentication handshake in IBSS mode upon having discovered a
+new station, and on the receiver resetting the state (removing
+and re-adding the station) on receiving the authentication
+packet.

+Subject: [PATCH] mac80211: fix regression in SSN handling of addba tx
+
+Some drivers that do their own sequence number allocation (e.g. ath9k) rely
+on being able to modify params->ssn on starting tx ampdu sessions.
+This was broken by a change that modified it to use sta->tid_seq[tid] instead.

+Subject: [PATCH] mac80211: send ADDBA requests using the tid/queue of the
+ aggregation session
+
+Sending them out on a different queue can cause a race condition where a
+number of packets in the queue may be discarded by the receiver, because
+the ADDBA request is sent too early.
+This affects any driver with software A-MPDU setup which does not allocate
+packet seqno in hardware on tx, regardless of whether iTXQ is used or not.
+The only driver I've seen that explicitly deals with this issue internally
+is mwl8k.

+Subject: [PATCH] mac80211: agg-tx: don't schedule_and_wake_txq() under
+ sta->lock
+
+When we call ieee80211_agg_start_txq(), that will in turn call
+schedule_and_wake_txq(). Called from ieee80211_stop_tx_ba_cb()
+this is done under sta->lock, which leads to certain circular
+lock dependencies, as reported by Chris Murphy:
+https://lore.kernel.org/r/CAJCQCtSXJ5qA4bqSPY=oLRMbv-irihVvP7A2uGutEbXQVkoNaw@mail.gmail.com
+
+In general, ieee80211_agg_start_txq() is usually not called
+with sta->lock held, only in this one place. But it's always
+called with sta->ampdu_mlme.mtx held, and that's therefore
+clearly sufficient.
+
+Change ieee80211_stop_tx_ba_cb() to also call it without the
+sta->lock held, by factoring it out of ieee80211_remove_tid_tx()
+(which is only called in this one place).
+
+This breaks the locking chain and makes it less likely that
+we'll have similar locking chain problems in the future.

+Subject: [PATCH] mac80211: minstrel_ht: reduce fluctuations in rate
+ probability stats
+
+In some scenarios when there is a lot of fluctuation in packet error rates,
+rate switching can be amplified when the statistics get skewed by time slots
+with very few tries.
+Make the input data to the moving average more smooth by adding the
+success/attempts count from the last stats window as well. This has the
+advantage of smoothing the data without introducing any extra lag to sampling
+rates.
+This significantly improves rate stability on a strong test link subjected to
+periodic noise bursts generated with a SDR

+Subject: [PATCH] mac80211: minstrel_ht: rework rate downgrade code and
+ max_prob rate selection
+
+The current fallback code for fast rate switching on potentially failing rates
+is triggering too often if there is some strong noise on the channel. This can
+lead to wild fluctuations in the rate selection.
+Additionally, switching down to max_prob_rate can create a significant gap down
+in throughput, especially when using only 2 spatial streams, because max_prob_rate
+is limited to using fewer streams than the max_tp rates.
+In order to improve throughput without reducing reliability too much, use the
+rate downgrade code for the max_prob_rate only, and allow the non-downgraded
+max_prob_rate to use as many spatial streams as the max_tp rates

+From: John Crispin <john@phrozen.org>
+Date: Wed, 15 Sep 2021 19:54:34 -0700
+Subject: [PATCH] nl80211: MBSSID and EMA support in AP mode
+
+Add new attributes to configure support for multiple BSSID
+and advanced multi-BSSID advertisements (EMA) in AP mode.
+
+- NL80211_ATTR_MBSSID_CONFIG used for per interface configuration.
+- NL80211_ATTR_MBSSID_ELEMS used to MBSSID elements for beacons.
+
+Memory for the elements is allocated dynamically. This change frees
+the memory in existing functions which call nl80211_parse_beacon(),
+a comment is added to indicate the new references to do the same.

+Date: Sat, 23 Oct 2021 11:10:50 +0200
+Subject: [PATCH] cfg80211: implement APIs for dedicated radar detection HW
+
+If a dedicated (off-channel) radar detection hardware (chain)
+is available in the hardware/driver, allow this to be used by
+calling the NL80211_CMD_RADAR_DETECT command with a new flag
+attribute requesting off-channel radar detection is used.
+
+Offchannel CAC (channel availability check) avoids the CAC
+downtime when switching to a radar channel or when turning on
+the AP.
+
+Drivers advertise support for this using the new feature flag
+NL80211_EXT_FEATURE_RADAR_OFFCHAN.

+Subject: [PATCH] cfg80211: move offchan_cac_event to a dedicated work
+
+In order to make cfg80211_offchan_cac_abort() (renamed from
+cfg80211_offchan_cac_event) callable in other contexts and
+without so much locking restrictions, make it trigger a new
+work instead of operating directly.
+
+Do some other renames while at it to clarify.

+ cfg80211_radar_event
+
+If necessary schedule offchan_cac_abort_wk work in cfg80211_radar_event
+routine adding offchan parameter to cfg80211_radar_event signature.
+Rename cfg80211_radar_event in __cfg80211_radar_event and introduce
+the two following inline helpers:
+- cfg80211_radar_event
+- cfg80211_offchan_radar_event
+Doing so the drv will not need to run cfg80211_offchan_cac_abort() after
+radar detection on the offchannel chain.

+Subject: [PATCH] cfg80211: rename offchannel_chain structs to background_chain
+ to avoid confusion with ETSI standard
+
+ETSI standard defines "Offchannel CAC" as:
+"Off-Channel CAC is performed by a number of non-continuous checks
+spread over a period in time. This period, which is required to
+determine the presence of radar signals, is defined as the Off-Channel
+CAC Time..
+Minimum Off-Channel CAC Time 6 minutes and Maximum Off-Channel CAC Time
+4 hours..".
+mac80211 implementation refers to a dedicated hw chain used for continuous
+radar monitoring. Rename offchannel_* references to background_* in
+order to avoid confusion with ETSI standard.

+Subject: [PATCH] mac80211: fix EAPoL rekey fail in 802.3 rx path
+
+mac80211 set capability NL80211_EXT_FEATURE_CONTROL_PORT_OVER_NL80211
+to upper layer by default. That means we should pass EAPoL packets through
+nl80211 path only, and should not send the EAPoL skb to netdevice diretly.
+At the meanwhile, wpa_supplicant would not regist sock to listen EAPoL skb
+on the netdevice.
+
+However, there is no contorl_port_protocol handler in mac80211 for 802.3 RX
+packets, mac80211 driver would pass up the EAPoL rekey frame to netdevice
+and wpa_supplicant would be never interactive with this kind of packets,
+if SUPPORTS_RX_DECAP_OFFLOAD is enabled. This causes STA always rekey fail

+Subject: [PATCH] mac80211: fix forwarded mesh frames AC & queue selection
+
+There are two problems with the current code that have been highlighted
+with the AQL feature that is now enbaled by default.
+
+First problem is in ieee80211_rx_h_mesh_fwding(),
+ieee80211_select_queue_80211() is used on received packets to choose
+the sending AC queue of the forwarding packet although this function
+should only be called on TX packet (it uses ieee80211_tx_info).
+This ends with forwarded mesh packets been sent on unrelated random AC
+queue. To fix that, AC queue can directly be infered from skb->priority
+which has been extracted from QOS info (see ieee80211_parse_qos()).
+
+Second problem is the value of queue_mapping set on forwarded mesh
+frames via skb_set_queue_mapping() is not the AC of the packet but a
+hardware queue index. This may or may not work depending on AC to HW
+queue mapping which is driver specific.
+
+Both of these issues lead to improper AC selection while forwarding
+mesh packets but more importantly due to improper airtime accounting
+(which is done on a per STA, per AC basis) caused traffic stall with
+the introduction of AQL.
+
+Fixes: cf44012810cc ("mac80211: fix unnecessary frame drops in mesh fwding")
+Fixes: d3c1597b8d1b ("mac80211: fix forwarded mesh frame queue mapping")

+Subject: [PATCH] mac80211: MBSSID support in interface handling
+
+Configure multiple BSSID and enhanced multi-BSSID advertisement (EMA)
+parameters in mac80211 for AP mode.
+
+For each interface, 'mbssid_tx_vif' points to the transmitting interface of
+the MBSSID set. The pointer is set to NULL if MBSSID is disabled.
+
+Function ieee80211_stop() is modified to always bring down all the
+non-transmitting interfaces first and the transmitting interface last.
