cfg80211/nl80211: support GTK rekey offload

2011-07-06T19:05:42+00:00

In certain circumstances, like WoWLAN scenarios, devices may implement (partial) GTK rekeying on the device to avoid waking up the host for it. In order to successfully go through GTK rekeying, the KEK, KCK and the replay counter are required. Add API to let the supplicant hand the parameters to the driver which may store it for future GTK rekey operations. Note that, of course, if GTK rekeying is done by the device, the EAP frame must not be passed up to userspace, instead a rekey event needs to be sent to let userspace update its replay counter.

cfg80211/nl80211: add support for scheduled scans

2011-05-11T19:12:26+00:00

Implement new functionality for scheduled scan offload. With this feature we can scan automatically at certain intervals. The idea is that the hardware can perform scan automatically and filter on desired results without waking up the host unnecessarily. Add NL80211_CMD_START_SCHED_SCAN and NL80211_CMD_STOP_SCHED_SCAN commands to the nl80211 interface. When results are available they are reported by NL80211_CMD_SCHED_SCAN_RESULTS events. The userspace is informed when the scheduled scan has stopped with a NL80211_CMD_SCHED_SCAN_STOPPED event, which can be triggered either by the driver or by a call to NL80211_CMD_STOP_SCHED_SCAN.

nl80211: New notification to discover mesh peer candidates.

2011-04-12T20:57:39+00:00

Notify userspace when a beacon/presp is received from a suitable mesh peer candidate for whom no sta information exists. Userspace can then decide to create a sta info for the candidate. If userspace is not ready to authenticate the peer right away, it can create the sta info with the authenticated flag unset and set it later. Signed-off-by: Javier Cardona Signed-off-by: John W.

cfg80211: Add nl80211 event for deletion of a station entry

2011-03-30T18:15:18+00:00

Indicate an NL80211_CMD_DEL_STATION event when a station entry in mac80211 is deleted to match with the NL80211_CMD_NEW_STATION event that is used when the entry was added. This is needed, e.g., to allow user space to remove a peer from RSN IBSS Authenticator state machine to avoid re-authentication and re-keying delays when the peer is not reachable anymore.

nl80211: Add notification for dropped Deauth/Disassoc

2010-12-16T20:22:30+00:00

Add a new notification to indicate that a received, unprotected Deauthentication or Disassociation frame was dropped due to management frame protection being in use. This notification is needed to allow user space (e.g., wpa_supplicant) to implement SA Query procedure to recover from association state mismatch between an AP and STA. This is needed to avoid getting stuck in non-working state when MFP (IEEE 802.11w) is used and a protected Deauthentication or Disassociation frame is dropped for any reason. After that, the station would silently discard any unprotected Deauthentication or Disassociation frame that could be indicating that the AP does not have association for the STA (when the Reason Code would be 6 or 7). IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism. Signed-off-by: Jouni Malinen Signed-off-by: John W. Linville

cfg80211: allow using CQM event to notify packet loss

2010-11-24T21:19:36+00:00

This adds the ability for drivers to use CQM events to notify about packet loss for specific stations (which could be the AP for the managed mode case). Since the threshold might be determined by the driver (it isn't passed in right now) it will be passed out of the driver to userspace in the event. Signed-off-by: Johannes Berg Signed-off-by: John W.

cfg80211/mac80211: extensible frame processing

2010-08-24T20:27:56+00:00

Allow userspace to register for more than just action frames by giving the frame subtype, and make it possible to use this in various modes as well. With some tweaks and some added functionality this will, in the future, also be usable in AP mode and be able to replace the cooked monitor interface currently used in that case.

cfg80211: Add connection quality monitoring support to nl80211

2010-03-24T20:02:37+00:00

Add support for basic configuration of a connection quality monitoring to the nl80211 interface, and basic support for notifying about triggered monitoring events. Via this interface a user-space connection manager may configure and receive pre-warning events of deteriorating WLAN connection quality, and start preparing for roaming in advance, before the connection is already lost. An example usage of such a trigger is starting scanning for nearby AP's in an attempt to find one with better connection quality, and associate to it before the connection characteristics of the existing connection become too bad or the association is even lost, leading in a prolonged delay in connectivity. The interface currently supports only RSSI, but it could be later extended to include other parameters, such as signal-to-noise ratio, if need for that arises.

cfg80211/mac80211: allow registering for and sending action frames

2010-02-15T21:14:15+00:00

This implements a new command to register for action frames that userspace wants to handle instead of the in-kernel rejection. It is then responsible for rejecting ones that it decided not to handle. There is no unregistration, but the socket can be closed for that. Frames that are not registered for will not be forwarded to userspace and will be rejected by the kernel, the cfg80211 API helps implementing that. Additionally, this patch adds a new command that allows doing action frame transmission from userspace. It can be used either to exchange action frames on the current operational channel (e.g., with the AP with which we are currently associated) or to exchange off-channel Public Action frames with the remain-on-channel command.
