4b9a395e29 WPS: Reduce struct wps_parse_attr size
Use shorter variables for storing the attribute lengths and group these
variables together to allow compiler to pack them more efficiently. This
reduces the struct size from 960 bytes to 760 bytes in 64-bit builds.
This reduces stack use in number of functions.

b664ef1c0d WPS: Reduce wps_ap_priority_compar() stack use
There is no need to maintain two concurrent instances of struct
wps_parse_attr in this function. Share a single structure for parsing
both IEs.

24fd20438f WPS: Fix num_probereq_cb clearing on DISABLE to avoid segfault
Reset hapd->num_probereq_cb to 0 on an interface deinit to avoid
unexpected behavior if the same interface is enabled again without fully
freeing the data structures. hostapd_register_probereq_cb() increments
hapd->num_probereq_cb by one and leaves all old values unchanged. In
this deinit+init case, that would result in the first entry in the list
having an uninitialized pointer and the next Probe Request frame
processing would likely cause the process to terminate on segmentation
fault.

This issue could be hit when hostapd was used with WPS enabled (non-zero
wps_state configuration parameter) and control interface command DISABLE
and ENABLE were used.

faf427645a TDLS: Use proper IE parsing routine for non-EAPOL-Key cases
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.

0e2412d086 Add option to reject authentication on 2.4 GHz from dualband STA
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

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
