cfg80211: Support key configuration for Beacon protection (BIGTK)

2020-02-24T09:35:48Z

IEEE P802.11-REVmd/D3.0 adds support for protecting Beacon frames using a new set of keys (BIGTK; key index 6..7) similarly to the way group-addressed Robust Management frames are protected (IGTK; key index 4..5). Extend cfg80211 and nl80211 to allow the new BIGTK to be configured. Add an extended feature flag to indicate driver support for the new key index values to avoid array overflows in driver implementations and also to indicate to user space when this functionality is available.

cfg80211: fix deadlocks in autodisconnect work

Use methods which do not try to acquire the wdev lock themselves.

cfg80211: Handle bss expiry during connection

2019-05-28T07:35:39Z

If the BSS is expired during connection, the connect result will trigger a kernel warning. Ideally cfg80211 should hold the BSS before the connection is attempted, but as the BSSID is not known in case of auth/assoc MLME offload (connect op) it doesn't. For those drivers without the connect op cfg80211 holds down the reference so it wil not be removed from list. Fix this by removing the warning and silently adding the BSS back to the bss list which is return by the driver (with proper BSSID set) or in case the BSS is already added use that. The requirements for drivers are documented in the API's. Signed-off-by: Chaitanya Tata [formatting fixes, keep old timestamp] Signed-off-by: Johannes Berg

cfg80211: call disconnect_wk when AP stops

2019-02-01T10:12:50Z

Since we now prevent regulatory restore during STA disconnect if concurrent AP interfaces are active, we need to reschedule this check when the AP state changes. This fixes never doing a restore when an AP is the last interface to stop. Or to put it another way: we need to re-check after anything we check here changes.

cfg80211: Prevent regulatory restore during STA disconnect in concurrent interfaces

2018-11-09T08:11:47Z

Currently when an AP and STA interfaces are active in the same or different radios, regulatory settings are restored whenever the STA disconnects. This restores all channel information including dfs states in all radios. For example, if an AP interface is active in one radio and STA in another, when radar is detected on the AP interface, the dfs state of the channel will be changed to UNAVAILABLE. But when the STA interface disconnects, this issues a regulatory disconnect hint which restores all regulatory settings in all the radios attached and thereby losing the stored dfs state on the other radio where the channel was marked as unavailable earlier. Hence prevent such regulatory restore whenever another active beaconing interface is present in the same or other radios. Signed-off-by: Sriram R Signed-off-by: Johannes Berg

cfg80211: add missing constraint for user-supplied VHT mask

cfg80211: clear wep keys after disconnection

2018-02-19T13:53:12Z

When a low level driver calls cfg80211_disconnected(), wep keys are not cleared. As a result, following connection requests will fail since cfg80211 internal state shows a connection is still in progress. Fix this by clearing the wep keys when disconnecting.
