eapol: Use handshake_state to store state Remove the keys and other data from struct eapol_sm, update device.c, netdev.c and wsc.c to use the handshake_state object instead of eapol_sm. This also gets rid of eapol_cancel and the ifindex parameter in some of the eapol functions where sm->handshake->ifindex can be used instead.

netdev: Refactor netdev_register_frame Rename netdev_register_frame to netdev_frame_watch_add and expose to be usable outside of netdev.c, add netdev_frame_watch_remove also. Update the Neighbor Report handling which was the only user of netdev_register_frame. The handler is now simpler because we use a lookup list with all the prefixes and individual frame handlers only see the frames matching the right prefix. This is also useful for the future Access-Point mode.

NETDEV_EVENT_DISCONNECT_BY_AP,
netdev: Emit DISCONNECT_BY_SME event on eapol failures There are situations when a CMD_DISCONNECT or deauthenticate will be issued locally because of an error detected locally where netdev would not be able to emit a event to the device object. The CMD_DISCONNECT handler can only send an event if the disconnect is triggered by the AP because we don't have an enum value defined for other diconnects. We have these values defined for the connect callback but those errors may happen when the connect callback is already NULL because a connection has been estabilshed. So add an event type for local errors. These situations may occur in a transition negotiation or in an eapol handshake failure during rekeying resulting in a call to netdev_handshake_failed.

netdev: Implement RSSI level notifications API Add an methods and an event using the new NL80211_EXT_FEATURE_CQM_RSSI_LIST kernel feature to request RSSI monitoring with notifications only when RSSI moves from one of the N intervals requested to another. device.c will call netdev_set_rssi_report_levels to request NETDEV_EVENT_RSSI_LEVEL_NOTIFY events every time the RSSI level changes, level meaning one of the intervals delimited by the threshold values passed as argument. Inside the event handler it can call netdev_get_rssi_level to read the new level. There's no fallback to periodic polling implemented in this patch for the case of older kernels and/or the driver not supporting NL80211_EXT_FEATURE_CQM_RSSI_LIST.

netdev/device: Combine watches There was somewhat overlapping functionality in the device_watch infrastructure as well as the netdev_event_watch. This commit combines the two into a single watch based on the netdev object and cleans up the various interface additions / removals. With this commit the interfaces are created when the netdev/device is switched to Powered=True state AND when the netdev iftype is also in the correct state for that interface. If the device is brought down, then all interfaces except the .Device interface are removed. This will make it easy to implement Device.Mode property properly since most nl80211 devices need to be brought into Powered=False state prior to switching the iftype.

netdev: station: fix status/reason code in callbacks This change cleans up the mess of status vs reason codes. The two types of codes have already been separated into different enumerations, but netdev was still treating them the same (with last_status_code). A new 'event_data' argument was added to the connect callback, which has a different meaning depending on the result of the connection (described inside netdev.h, netdev_connect_cb_t). This allows for the removal of netdev_get_last_status_code since the status or reason code is now passed via event_data. Inside the netdev object last_status_code was renamed to last_code, for the purpose of storing either status or reason. This is only used when a disconnect needs to be emitted before failing the connection. In all other cases we just pass the code directly into the connect_cb and do not store it. All ocurrences of netdev_connect_failed were updated to use the proper code depending on the netdev result. Most of these simply changed from REASON_CODE_UNSPECIFIED to STATUS_CODE_UNSPECIFIED. This was simply for consistency (both codes have the same value). netdev_[authenticate|associate]_event's were updated to parse the status code and, if present, use that if their was a failure rather than defaulting to UNSPECIFIED.

Doing it this way unifies the code path into a single switch statment to handle all failures. In addition, we pass the RSSI level index as event data to RSSI_LEVEL_NOTIFY.

A helper API (netdev_get_current_station) was added as a convenience which automatically passes handshake->aa as the MAC.

netdev: Implement netdev_fast_transition Build and send the FT Authentication Request frame, the initial Fast Transition message. In this version the assumption is that once we start a transition attempt there's no going back so the old handshake_state, scan_bss, etc. can be replaced by the new objects immediately and there's no point at which both the old and the new connection states are needed. Also the disconnect event for the old connection is implicit. At netdev level the state during a transition is almost the same with a new connection setup. The first disconnect event on the netlink socket after the FT Authenticate is assumed to be the one generated by the kernel for the old connection. The disconnect event doesn't contain the AP bssid (unlike the deauthenticate event preceding it), otherwise we could check to see if the bssid is the one we are interested in or could check connect_cmd_id assuming a disconnect doesn't happen before the connect command finishes.

int netdev_fast_transition(struct netdev *netdev, struct scan_bss *target_bss,
netdev_connect_cb_t cb);
ft: netdev: station: support FT-over-DS FT-over-DS is a way to do a Fast BSS Transition using action frames for the authenticate step. This allows a station to start a fast transition to a target AP while still being connected to the original AP. This, in theory, can result in less carrier downtime. The existing ft_sm_new was removed, and two new constructors were added; one for over-air, and another for over-ds. The internals of ft.c mostly remain the same. A flag to distinguish between air/ds was added along with a new parser to parse the action frames rather than authenticate frames. The IE parsing is identical. Netdev now just initializes the auth-proto differently depending on if its doing over-air or over-ds. A new TX authenticate function was added and used for over-ds. This will send out the IEs from ft.c with an FT Request action frame. The FT Response action frame is then recieved from the AP and fed into the auth-proto state machine. After this point ft-over-ds behaves the same as ft-over-air (associate to the target AP). Some simple code was added in station.c to determine if over-air or over-ds should be used. FT-over-DS can be beneficial in cases where the AP is directing us to roam, or if the RSSI falls below a threshold. It should not be used if we have lost communication to the AP all (beacon lost) as it only works while we can still talk to the original AP.

Since the current AP Dbus API has nothing related to configuration items such as freq/channel or RSN elements they are hard coded, and will be for Ad-Hoc as well (for now).

netdev: Implement RSSI level notifications API Add an methods and an event using the new NL80211_EXT_FEATURE_CQM_RSSI_LIST kernel feature to request RSSI monitoring with notifications only when RSSI moves from one of the N intervals requested to another. device.c will call netdev_set_rssi_report_levels to request NETDEV_EVENT_RSSI_LEVEL_NOTIFY events every time the RSSI level changes, level meaning one of the intervals delimited by the threshold values passed as argument. Inside the event handler it can call netdev_get_rssi_level to read the new level. There's no fallback to periodic polling implemented in this patch for the case of older kernels and/or the driver not supporting NL80211_EXT_FEATURE_CQM_RSSI_LIST.

netdev: add netdev_get_station/current_station This adds a generalized API for GET_STATION. This API handles calling and parsing the results into a new structure, netdev_station_info. This results structure will hold any data needed by consumers of netdev_get_station. A helper API (netdev_get_current_station) was added as a convenience which automatically passes handshake->aa as the MAC. For now only the RSSI is parsed as this is already being done for RSSI polling/events. Looking further more info will be added such as rx/tx rates and estimated throughput.

netdev: fixed key setting failure If netdev fails to set the keys, there was no way for device/ap to know. A new handshake event was added for this. The key setting failure function was also fixed to support both AP/station iftypes. It will now automatically send either a disconnect or del_station depending on the interface type. In similar manner, netdev_handshake_failed was also modified to support both AP/station iftypes. Now, any handshake event listeners should call netdev_handshake_failed upon a handshake failure event, including AP.

netdev/device: Combine watches There was somewhat overlapping functionality in the device_watch infrastructure as well as the netdev_event_watch. This commit combines the two into a single watch based on the netdev object and cleans up the various interface additions / removals. With this commit the interfaces are created when the netdev/device is switched to Powered=True state AND when the netdev iftype is also in the correct state for that interface. If the device is brought down, then all interfaces except the .Device interface are removed. This will make it easy to implement Device.Mode property properly since most nl80211 devices need to be brought into Powered=False state prior to switching the iftype.

netdev: added station watch For Ad-Hoc networks, the kernel takes care of auth/assoc and issues a NEW_STATION event when that is complete. This provides a way to notify when NEW_STATION events occur as well as forward the MAC of the station to Ad-Hoc. The two new API's added: - netdev_station_watch_add() - netdev_station_watch_remove()
