A new hostapd.conf parameter, wps_rf_bands, can now be used to fix the
RF Bands value in cases where hw_mode is not set or when operating a
dual band dual concurrent AP.

When hostapd controls multiple radios, WPS operations are started on
all interfaces. However, when the provisioning run had been completed
successfully, actiove WPS mode was stopped only a single interface. Fix
this to iterate through all interfaces so that this is handled
consistently with the starting of WPS operation.

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.

Send the connection events from P2P group to both the group interface
and parent interface ctrl_ifaces to make it easier for external monitor
programs to see these events without having to listen to all group
interfaces when virtual group interfaces are used.

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
check from driver_*.c into ieee802_1x_receive(), but failed to take into
account that wired networks and driver_wired.c do not mark the STA entry
associated. Fix this by skipping the check if the driver wrapper is
using a wired network.

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.

The new event can be used when EAPOL TX status can't be reported as a

This is a workaround for Windows 7 supplicant rejecting WPA msg 3/4
in case it used Secure=1 in msg 2/4. This can happen, e.g., when
rekeying PTK after EAPOL-Key Error Request (Michael MIC failure)
from the supplicant.

Commit c2ff13c533 broke this with a

hapd->time_adv cannot really be NULL if hostapd_update_time_adv()
returns success, but this construction seems to be too difficult
for some static analyzers. While this change is not really needed
in practice, it makes it easier to go through warnings from such
analyzers.

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.

The eloop timeout to stop TKIP countermeasures has to be canceled

This was included in the AP configuration parameters, but there has
been no way to set it to anything else than the default automatic
mode. Remove this parameter and just hardcode ERP determination to
follow the automatic mode.
hostapd_wpa_auth_conf() is called on uninitialized memory and the
conditional blocks in this function may leave some fields into
uninitialized state. This can result in unexpected behavior elsewhere
since some of the variables may be used without matching #ifdef
blocks. Fix this by zeroing the memory.
The Query Response Length Limit is not allowed to be zero when
this is sent by the AP. Use 0x7F to indicate that the limit is
based on maximum number of GAS fragments.
For P2P, the p2p_connect takes in device address argument to make a
connection. However the connected event AP-STA-CONNECTED comes with
interface address. The application listening on events would find it
difficult to map interface address to the p2p device address which is
provided for connection.
Append P2P Device Address to AP-STA-CONNECTED event for P2P Client
connection. This will help applications to easily map the P2P Interface
Address to P2P Device Address on CONNECTED event. For non-P2P case, it
will just print the usual STA MAC address alone.

This offloads the station polling to driver wrappers, which may offload
it again to the driver. The hostap driver wrapper uses "real" data
frames while nl80211 uses null data frames.
Also add a specific event to indicate that a poll was successful for
future use with the nl80211 driver.
