When wpa_init() in __mesh_rsn_auth_init() failed, empty rsn->auth caused
segmentation fault due to NULL pointer dereference when wpa_deinit() was
called. Fix this by checking the pointer before executing deinit steps.

The RSN IE is required by IEEE Std 802.11-2012 on SAE use case:
Table 8-262 Mesh Peering Open frame Action field format
Table 8-263 Mesh Peering Confirm frame Action field format
Add the RSN IE to these frames.

wpa_supplicant_parse_ies() was never supposed to be used as a generic IE
parser, i.e., it is for the specific purpose of parsing EAPOL-Key Key
Data IEs and KDEs. TDLS used this function for parsing generic AP IEs
and while that works, it resulted in confusing "WPA: Unrecognized
EAPOL-Key Key Data IE" debug messages. Clean this up by using
ieee802_11_parse_elems() for the cases where generic IEs are being
parsed.

This extends the previous tracking design to add a station entry based
on other management frames than Probe Request frames. For example, this
covers a case where the station is using passive scanning.

Double the buffer length from 2048 to 4096 to match the length used
currently in wpa_supplicant. This allows wpa_gui to retrieve information

The new no_auth_if_seen_on=<ifname> parameter can now be used to
configure hostapd to reject authentication from a station that was seen
on another radio.
This can be used with enabled track_sta_max_num configuration on another
interface controlled by the same hostapd process to reject
authentication attempts from a station that has been detected to be
capable of operating on another band, e.g., to try to reduce likelihood
of the station selecting a 2.4 GHz BSS when the AP operates both a 2.4
GHz and 5 GHz BSS concurrently.
Note: Enabling this can cause connectivity issues and increase latency for
connecting with the AP.

The new no_probe_resp_if_seen_on=<ifname> parameter can now be used to
configure hostapd to not reply to group-addressed Probe Request from a
station that was seen on another radio.
This can be used with enabled track_sta_max_num configuration on another
interface controlled by the same hostapd process to restrict Probe
Request frame handling from replying to group-addressed Probe Request
frames from a station that has been detected to be capable of operating
on another band, e.g., to try to reduce likelihood of the station
selecting a 2.4 GHz BSS when the AP operates both a 2.4 GHz and 5 GHz
BSS concurrently.
Note: Enabling this can cause connectivity issues and increase latency
for discovering the AP.

hostapd can now be configured to track unconnected stations based on
Probe Request frames seen from them. This can be used, e.g., to detect
dualband capable station before they have associated. Such information
could then be used to provide guidance on which colocated BSS to use in
case of a dualband AP that operates concurrently on multiple bands under
the control of a single hostapd process.

For now, there is no support for passing extended_capa pointers through
the driver_privsep.c interface from wpa_priv. Avoid leaving bogus
pointers by explicitly clearing these on both wpa_priv and
wpa_supplicant sides.

DSSS/CCK rate support in 40 MHz has to be set to 0 for 5 GHz band since
this mechanism is designed only for the 2.4 GHz band. Clear

neither 11b nor 11g.

This adds a new helper function wpa_ctrl_open2() that can be used

Previously, the EAP-WSC peer state machine ended up just ignoring an
error and waiting for a new message from the AP. This is not going to
recover the exchange, so simply force the connection to terminate
immediately.

Previously, the BSS command returned an error if the WSC IE(s) in scan
results could not be parsed. This may be not ideal for all cases, to
instead of rejecting the command completely, return all other
information apart from the WPS information in such a case.
