2023-06-21wifi: mac80211: fix CRC calculation for extended elemsJohannes Berg
For extended elements, we currently only calculate the CRC for some of them, but really we should do it also for the rest that we care about, such as EHT operation and multi- link. Also, while at it, it seems we should do it even if they aren't well-formed, so we notice if that changes.

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().

2023-06-21soundwire: stream: Make master_list ordered to prevent deadlocksRichard Fitzgerald
Always add buses to the stream->master_list in a fixed order. The unique bus->id is used to order the adding of buses to the list. This prevents lockdep asserts and possible deadlocks on streams that have multiple buses. sdw_acquire_bus_lock() takes bus_lock in the order that buses are listed in stream->master_list. do_bank_switch() takes all the msg_lock in the same order. To prevent a lockdep assert, and a possible real deadlock, the relative order of taking these mutexes must always be the same. For example, if a stream takes the mutexes in the order (bus0, bus1) lockdep will assert if another stream takes them in the order (bus1, bus0). More complex relative ordering will also assert, for example if two streams take (bus0, bus1) and (bus1, bus2), then a third stream takes (bus2, bus0). Previously sdw_stream_add_master() simply added the given bus to the end of the list, requiring the caller to guarantee that buses are added in a fixed order. This isn't reasonable or necessary - it's an internal implementation detail that should not be exposed by the API. It doesn't really make sense when there could be multiple independent calling drivers, to say "you must add your buses in the same order as a different driver, that you don't know about, added them".

2023-06-21soundwire: bus: Prevent lockdep asserts when stream has multiple busesRichard Fitzgerald
Give the bus_lock and msg_lock of each bus a different unique key so that it is possible to acquire the locks of multiple buses without lockdep asserting a possible deadlock. Using mutex_init() to initialize a mutex gives all those mutexes the same lock class. Lockdep checking treats it as an error to attempt to take a mutex while already holding a mutex of the same class. This causes a lockdep assert when sdw_acquire_bus_lock() attempts to lock multiple buses, and when do_bank_switch() takes multiple msg_lock.

2023-06-21hwtracing: hisi_ptt: Fix potential sleep in atomic contextYicong Yang
We're using pci_irq_vector() to obtain the interrupt number and then bind it to the CPU start perf under the protection of spinlock in pmu::start(). pci_irq_vector() might sleep since [1] because it will call msi_domain_get_virq() to get the MSI interrupt number and it needs to acquire dev->msi.data->mutex. Getting a mutex will sleep on contention. So use pci_irq_vector() in an atomic context is problematic. This patch cached the interrupt number in the probe() and uses the cached data instead to avoid potential sleep.

The PTT can only filter the traced TLP headers by the Root Ports or the Requester ID of the Endpoint, which are located on the same PCIe core of the PTT device. The filter value used is derived from the BDF number of the supported Root Port or the Endpoint. It's not friendly enough for the users since it requires the user to be familiar enough with the platform and calculate the filter value manually. This patch export the available filters through sysfs. Each available filters is presented as an individual file with the name of the BDF number of the related PCIe device. The files are created under $(PTT PMU dir)/available_root_port_filters and $(PTT PMU dir)/available_requester_filters respectively. The filter value can be known by reading the related file.

2023-06-21wifi: rtw88: fix not entering PS mode after AP stopsPo-Hao Huang
Without this patch, firmware only track beacons for port 0 and since we will always start AP on port 0, this results in misbehavior of power saving mode on other ports after AP stops. The "default port" H2C command is used to notify which port should firmware track. Update the correct settings to firmware so power saving mode can work properly.

2023-06-21wifi: rtw88: refine register based H2C commandPo-Hao Huang
Since register based H2C commands don't need endian conversion. Introduce a new API that don't do conversion and send it directly. New caller are expected to encode with cpu order and gradually replace the old ones.

2023-06-21wifi: rtw88: Stop high queue during scanPo-Hao Huang
When traversing channel list, TX in high queue should be disabled along with beacon function, so packets won't be sent to incorrect channels.

2023-06-21wifi: rtw88: Skip high queue in hci_flushPo-Hao Huang
The flush period may not always intersect with DTIM and when that happens, an error log "timed out to flush pci TX ring[6]" is shown. Bypass this since hardware will do proper transmission on the next DTIM period for broadcast/multicast packets in high queue.

2023-06-21wifi: rtw88: Fix AP mode incorrect DTIM behaviorPo-Hao Huang
Broadcast and multicast packets in high queue should be transmitted all at once during DTIM. But without proper settings, hardware fails to recognize that there are multiple packets and fetches only one. Fix this by signaling hardware with more data bit set when there are packets in the high queue.

2023-06-21wifi: rtw88: process VO packets without workqueue to avoid PTK rekey failedChih-Kang Chang
In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through nl80211_tx_control_port() and triggers wake_tx_queue() in the driver. Then, it sends nl80211_new_key() to configure a new key in mac80211. However, in wake_tx_queue(), a workqueue is used to process the tx packet, which might cause the driver to process the EAPOL packet later than nl80211_new_key(). As a result, the EAPOL 4/4 packet is dropped by mac80211 due to the rekey configuration being finished. The EAPOL packets belongs to VO packets that need high priority. Therefore, we process VO packets directly without workqueue to ensure that packets can process immediately. VO is normally used by voice application that is low traffic load and low latency, that doesn't affect user experience.

2023-06-21wifi: rtw88: Fix action frame transmission fail before associationPo-Hao Huang
For combo chips, antennas were controlled by bluetooth only during power on. If WiFi wish to do transmission, notification to the coexistence module are required. Previously we only do this before authentication. To allow transmission before auth, such as management TX, now we start the initiation of coexistence earlier so antennas are shared between WiFi and bluetooth after set_channel(), and frames could then be sent.
