Jouni Malinen 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.

Jouni Malinen 964f64e2ee Add option to ignore Probe Request frames on 2.4 GHz from dualband STA
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.

Jouni Malinen a65a9b8d67 hostapd: Add mechanism to track unconnected stations
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.

Jouni Malinen d9c807cab1 Fix key derivation for Suite B 192-bit AKM to use SHA384
While the EAPOL-Key MIC derivation was already changed from SHA256 to

Fix this by using HMAC-SHA384 instead of HMAC-SHA256 when deriving PTK

Anton Nayshtut 748febf344 hostapd: Add DUP_NETWORK global control interface command
This adds a new global control interface command DUP_NETWORK with the

DUP_NETWORK src_ifname dst_ifname param

The currently supported parameters:
  wpa
  wpa_key_mgmt
  wpa_pairwise
  rsn_pairwise
  wpa_passphrase
  wpa_psk

The specified configuration parameter is copied from the source
interface to the destination interface. The main use for this is to
allow cloning of security configuration without having to expose the
keys from the hostapd process.

CONFIG_TESTING_OPTIONS=y. For other builds, the TEST_FAIL() macro is
defined to return 0 to allow the compiler to remove the test code from
normal production builds.

based on call backtrace.

Jouni Malinen b4c0f58452 Clear allocated debug message buffers explicitly
When hostapd or wpa_supplicant is run in debug more with key material
prints allowed (-K on the command line), it is possible for passwords

cases end up allocating a temporary buffer from the heap for processing
purposes, a copy of such password may remain in heap. Clear these
temporary buffers explicitly to avoid causing issues for hwsim test
