wifi: cfg80211: stop radar detection in cfg80211_leave()

2025-11-24T12:05:23+00:00

If an interface is set down or, per the previous patch, changes type, radar detection for it should be cancelled. This is done for AP mode in mac80211 (somewhat needlessly, since cfg80211 can do it, but didn't until now), but wasn't handled for mesh, so if radar detection was started and then the interface set down or its type switched (the latter sometimes happning in the hwsim test 'mesh_peer_connected_dfs'), radar detection would be around with the interface unknown to the driver, later leading to some warnings around chanctx usage.

wifi: cfg80211: hide scan internals

Hide the internal scan fields from mac80211 and drivers, the 'notified' variable is for internal tracking, and the 'info' is output that's passed to cfg80211_scan_done() and stored only for delayed userspace notification.

This information is exposed to userspace but not drivers. Make this field public so that drivers are also able to access it. The information is for example useful for link selection to determine whether the BSS corresponding to an MLO link has been seen in a recent scan.

wifi: cfg80211: skip indicating signal for per-STA profile BSSs

2024-09-06T10:56:33+00:00

Currently signal of the BSS entry generated from the per-STA profile indicated as zero, but userspace may consider it as high signal strength since 0 dBm is a valid RSSI value. To avoid this don't report the signal to userspace when the BSS entry created from a per-STA profile.
