2024-06-26wifi: brcmsmac: advertise MFP_CAPABLE to enable WPA3Arend van Spriel
After being asked about support for WPA3 for BCM43224 chipset it was found that all it takes is setting the MFP_CAPABLE flag and mac80211 will take care of all that is needed [1].

2024-06-26wifi: mac80211: fix NULL dereference at band check in starting tx ba sessionZong-Zhe Yang
In MLD connection, link_data/link_conf are dynamically allocated. They don't point to vif->bss_conf. So, there will be no chanreq assigned to vif->bss_conf and then the chan will be NULL. Tweak the code to check ht_supported/vht_supported/has_he/has_eht on sta deflink.

This isn't related to whether or not "fw can be loaded", but rather requesting that ME go into a state where doing a product reset is safe. This is related to FW load only in the specific case of where it's used today in iwlmvm, notably when it's known that the firmware itself will (or at least may) do a product reset during load. Clarify the documentation. I was tempted to rename things too, but on the ME side it really is also called PLDR (which is a Windows term and may not even match the complete behaviour since doing a full product reset from the driver also requires calling an ACPI method first.) So keep the name aligned with ME.

2024-06-26wifi: iwlwifi: mvm: rename 'pldr_sync'Johannes Berg
PLDR (product level device reset) is a Windows term, and is something the driver triggers there, AFAICT. Really what 'pldr_sync' here wants to capture is whether or not the firmware will/may do a product reset during initialization, which makes the device drop off the bus, requiring a rescan. If this is the case, obviously the init will fail/time out, so we don't want to report all kinds of errors etc., hence this tracking variable. Rename it to 'fw_product_reset' to capture the meaning better.

2024-06-26wifi: mac80211: restrict public action ECSA frame handlingJohannes Berg
Public action extended channel switch announcement (ECSA) frames cannot be protected well, the spec is unclear about what should happen in the presence of stations that can receive protected dual and stations that cannot. Mitigate these issues by not treating public action frames as the absolute truth, only treat them as a hint to stop transmitting (quiet mode), and do the remainder of the CSA handling only when receiving the next beacon (or protected action frame) that contains the CSA; or, if it doesn't, simply stop being quiet and continue operating normally. This limits the exposure to malicious ECSA public action frames, since they cannot cause a disconnect now, only a short interruption in traffic.
