The 100 ms timeout on retransmitting group key message can be too short
for stations that are in power save mode or if there is a large number
of association stations. While the retransmission of the EAPOL-Key frame
should allow this to be recovered from, it is useful to avoid
unnecessary frames to save soem CPU and power.

Add a new persistent group network block field, p2p_client_list, to
maintain a list of P2P Clients that have connected to a persistent
group. This allows GO of a persistent group to figure out more easily
whether re-invocation of a persistent group can be used with a specific
peer device.

This allows per-device PSK to be configured for WPA-Personal using a
RADIUS authentication server. This uses RADIUS-based MAC address ACL
(macaddr_acl=2), i.e., Access-Request uses the MAC address of the
station as the User-Name and User-Password. The WPA passphrase is
returned in Tunnel-Password attribute in Access-Accept. This
functionality can be enabled with the new hostapd.conf parameter,
wpa_psk_radius.

Testing code can now be enabled in the hostapd RADIUS server to dump
each derived MSK into a text file (e.g., to be used as an input to
wlantest). This functionality is not included in the default build
and can be enabled by adding the following line to hostapd/.config:
CFLAGS += -DCONFIG_RADIUS_TEST
The MSK dump file is specified with dump_msk_file parameter in
hostapd.conf (path to the dump file). If this variable is not set,
MSK dump mechanism is not enabled at run time.

When hostapd controls multiple radios, WPS operations are started on

Commit 628d54639a introduced number
of new WPS related ctrl_iface messages to hostapd. Some of these
were for ER events which do not make any sense to hostapd that
cannot operate as an ER. The WPS_EV_ER_SET_SELECTED_REGISTRAR one
from wps_registrar_sel_registrar_changed_event() was especially
problematic since it can cause wpa_supplicant ER code segfault due
to missing event data.
Revert all the ER specific changes from commit
628d54639a to get rid of the segfault
and undesired extra code in hostapd.

If the station is indicating use of WPS, WSC IE should be added into the
(Re)Association Response frame. This is clear for the case when WSC IE
was included in the (Re)Association Request frame. However, even the
WLAN_STA_MAYBE_WPS case may actually indicate use of WPS. Assume that to
be the case when WPA/WPA2 is enabled (i.e., when the STA does not
include WPA/RSN/WSC IE while AP has WPA/RSN enabled).

Commit 940a0ce970 moved the STA associated

Some client implementations only wait a few ms after sending a probe
request while scanning. Since probe responses are always sent at a low
rate this can eat quite some airtime and it might be impossible to get
the frame out before the client leaves the channel again. If the client
leaves before all probe reponses where acked this can cause the probe
reponse to be retried quite often consuming even more airtime.
Hence, add a new noack flag to the driver's send_mlme callback that
allows hostapd to request whether the driver should expect an ACK for
this frame or not.
Use the new noack-policy only for broadcast probe requests that contain
a wildcard SSID.

In some situations it might be benefical to send a unicast frame without
the need for getting it ACKed (probe responses for example). In order to
achieve this add a new noack parameter to the drivers send_mlme callback
that can be used to advise the driver to not wait for an ACK for this
frame.

Some stations have been reported to send EAPOL-Key Error Reports
indicating Michael MIC failures even when the cipher is not TKIP
(e.g., when the network is using only CCMP). Ignore such reports
to avoid starting TKIP countermeasures unnecessarily. This can
prevent certaint types of denial of service attacks by insiders,
but mostly this is to work around invalid station implementations.
