2023-12-22dt-bindings: crypto: qcom-qce: constrain clocks for IPQ9574 QCEKrzysztof Kozlowski
Binding marks several devices as compatible with IPQ4019 QCE. They have different number of clocks, thus the fallback does not define the clock constraints per variant and each specific compatible should have its clocks in if:then: section. Add missing clocks description for IPQ9574 QCE.

eSR is activated when a chanctx is assigned to more than one link. During eSR activation we should disable RLC for both phys, and configure the FW with a special phy command for both phys. Currently we assign the phy_ctxt to the link only after eSR activation, so RLC is not disabled for the new phy_ctxt, and a cmd is not sent to FW.

2023-12-21wifi: mac80211: add a driver callback to check active_linksMiri Korenblit
During ieee80211_set_active_links() we do (among the others): 1. Call drv_change_vif_links() with both old_active and new_active 2. Unassign the chanctx for the removed link(s) (if any) 3. Assign chanctx to the added link(s) (if any) 4. Call drv_change_vif_links() with the new_active links bitmap The problem here is that during step #1 the driver doesn't know whether we will activate multiple links simultaneously or are just doing a link switch, so it can't check there if multiple links are supported/enabled. (Some of the drivers might enable/disable this option dynamically) And during step #3, in which the driver already knows that, returning an error code (for example when multiple links are not supported or disabled), will cause a warning, and we will still complete the transition to the new_active links. (It is hard to undo things in that stage, since we released channels etc.) Therefore add a driver callback to check if the desired new_active links will be supported by the driver or not. This callback will be called in the beginning of ieee80211_set_active_links() so we won't do anything before we are sure it is supported.

2023-12-21wifi: cfg80211: free beacon_ies when overridden from hidden BSSBenjamin Berg
This is a more of a cosmetic fix. The branch will only be taken if proberesp_ies is set, which implies that beacon_ies is not set unless we are connected to an AP that just did a channel switch. And, in that case we should have found the BSS in the internal storage to begin with.

2023-12-21wifi: mac80211: allow 64-bit radiotap timestampsJohannes Berg
When reporting the radiotap timestamp, the mactime field is usually unused, we take the data from the device_timestamp. However, there can be cases where the radiotap timestamp is better reported as a 64-bit value, so since the mactime is free, add a flag to support using the mactime as a 64-bit radiotap timestamp.

2023-12-21wifi: mac80211: Skip association timeout update after comeback rejectionJouni Malinen
It is possible for the TX status report for the (Re)Association Request frame to be delayed long enough for the AP's (Re)Association Response frame to be received and processed before it. If that were to happen for a case where the AP rejects the association with indication to come back later, the association timeout and retry state should not be modified anymore with the TX status information that would be processed after this. Updating the association timeout in such a reverse order of events could result in shortening the timeouts for the association comeback mechanism and that could result in the association failing. Track whether we have already processed association rejection with comeback time and if so, skip the timeout and retry update on any following TX status report.
