2024-02-08ASoC: SOF: ipc3-topology: Fix pipeline tear down logicRanjani Sridharan
With the change in the widget free logic to power down the cores only when the scheduler widgets are freed, we need to ensure that the scheduler widget is freed only after all the widgets associated with the scheduler are freed. This is to ensure that the secondary core that the scheduler is scheduled to run on is kept powered on until all widgets that need them are in use. While this works well for dynamic pipelines, in the case of static pipelines the current logic does not take this into account and frees all widgets in the order they occur in the widget_list. So, modify this to ensure that the scheduler widgets are freed only after all other types of widgets in the widget_list are freed.

2024-02-08ASoC: cs35l56: Fix deadlock in ASP1 mixer register initializationRichard Fitzgerald
Rewrite the handling of ASP1 TX mixer mux initialization to prevent a deadlock during component_remove(). The firmware can overwrite the ASP1 TX mixer registers with system-specific settings. This is mainly for hardware that uses the ASP as a chip-to-chip link controlled by the firmware. Because of this the driver cannot know the starting state of the ASP1 mixer muxes until the firmware has been downloaded and rebooted. The original workaround for this was to queue a work function from the dsp_work() job. This work then read the register values (populating the regmap cache the first time around) and then called snd_soc_dapm_mux_update_power(). The problem with this is that it was ultimately triggered by cs35l56_component_probe() queueing dsp_work, which meant that it would be running in parallel with the rest of the ASoC component and card initialization. To prevent accessing DAPM before it was fully initialized the work function took the card mutex. But this would deadlock if cs35l56_component_remove() was called before the work job had completed, because ASoC calls component_remove() with the card mutex held. This new version removes the work function. Instead the regmap cache and DAPM mux widgets are initialized the first time any of the associated ALSA controls is read or written.

2024-02-08wifi: iwlwifi: mvm: don't set replay counters to 0xffJohannes Berg
The firmware (later) actually uses the values even for keys that are invalid as far as the host is concerned, later in rekeying, and then only sets the low 48 bits since the PNs are only 48 bits over the air. It does, however, compare the full 64 bits later, obviously causing problems. Remove the memset and use kzalloc instead to avoid any old heap data leaking to the firmware. We already init all the other fields in the struct anyway. This leaves the data set to zero for any unused fields, so the firmware can look at them safely even if they're not used right now.

2024-02-08wifi: iwlwifi: mvm: fix erroneous queue index maskJohannes Berg
When retrieving the queue index ("SCD SSN") from the TX response, it's currently masked with 0xFFF. However, now that we have queues longer than 4k, that became wrong, so make the mask depend on the hardware family. This fixes an issue where if we get a single frame reclaim while in the top half of an 8k long queue, we'd reclaim-wrap the queue twice (once on this and then again on the next non-single reclaim) which at least triggers the WARN_ON_ONCE() in iwl_txq_reclaim(), but could have other negative side effects (such as unmapping a frame that wasn't transmitted yet, and then taking an IOMMU fault) as well.

2024-02-08wifi: mac80211: refactor STA CSA parsing flowsMichael-CY Lee
The new Wi-Fi Standard (IEEE Std 802.11-2020 9.4.2.160) specifies that the Wide Bandwidth Channel Switch (WBCS) Element subfields have the same definitions as VHT operation information if the operating band is not S1G. The problem comes when the BSS is in 6 GHz band, the STA parses the WBCS Element by ieee80211_chandef_vht_oper(), which checks the capabilities for HT/VHT mode, not HE/EHT mode. This patch refactors STA CSA parsing flow so that the corresponding capabilities can be checked. Also, it adds the way to use op_class in ECSA Element to build a new chandef. In summary, the new steps for STA to handle CSA event are: 1. build the new chandef from one of the CSA-related (Sub)Elements in following order, - Bandwidth Indication (Sub)Element - Wide Bandwidth Channel Switch (Sub)Element - Operating class in Extended Channel Switch Announcement Element - Channel Switch Announcement Element 2. convert the new chandef into operation information according to the operating band in order to check if the new chandef fits STA's capabilities. 3. downgrade the bandwidth until current bandwidth is not disabled.

2024-02-08wifi: mac80211: don't use sband->band earlyJohannes Berg
Some drivers may (notably mt76 does) not set up sband->band before registering, and cfg80211 will fill it in later. But since the HT/HE capability check mac80211 required it to be initialized already, otherwise failing things. This really isn't necessary though since the code is iterating the list of bands, and has the 'band' variable available. Fix it to not require the sband->band to be initialized already.
