This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter
-b<phyname>:<config file name> is used to define one or more virtual

interface. The radio parameters in the configuration files have to be
identical.
This can be used as an alternative for the bss=<ifname> separator and
multiple BSSes in a single configuration file design while still

When using OpenSSL with TLS-based EAP methods, wpa_supplicant can now be
configured to use OCSP stapling (TLS certificate status request) with
ocsp=1 network block parameter. ocsp=2 can be used to require valid OCSP
response before connection is allowed to continue.
hostapd as EAP server can be configured to return cached OCSP response
using the new ocsp_stapling_response parameter and an external mechanism
for updating the response data (e.g., "openssl ocsp ..." command).
This allows wpa_supplicant to verify that the server certificate has not
been revoked as part of the EAP-TLS/PEAP/TTLS/FAST handshake before
actual data connection has been established (i.e., when a CRL could not
be fetched even if a distribution point were specified).

Currently, hostapd_get_vlan_id_ifname() is used to determine if a given

Currently, struct hostapd_vlan is a per-BSS data structure which
also contains informations about whether to remove the bridge
or clear wlan / tagged-vlan interface from the bridge.
In a multi-interface multi-BSS setup, this can lead to the following
race condition:
1. wlan0 creates VLAN A, sets DVLAN_CLEAN_BR and DVLAN_CLEAN_VLAN_PORT
2. wlan1 creates VLAN A, does not set DVLAN_CLEAN_BR and
DVLAN_CLEAN_VLAN_PORT as already there
3. wlan0 removes VLAN A, removes tagged-interface from the bridge
but not the bridge.
Now wlan1 VLAN A is unusable due to the missing uplink.
4. wlan1 removes VLAN A, does not cleanup
Solution:
This requires an inter-BSS inter-interface data structure to track the
bridge / bridge port usage within hostapd. This data structure could
also be used to track any other device-has-been-created-by-hostapd
information or when regarding interface freeing.

There was an issue with EAPOL frame exchanges in a multi-BSS
configuration when a station switches between the BSSes controlled by
the same hostapd process. When processing the EAPOL packet, the array of
virtual APs (iface->bss) is searched looking for the station that sent
the packet in order to identify which signal context should be used
during processing. The first match of the station in its list gets used
in the ieee802_1x_receive() function. However, even after a station has
disassociated, it remains in the list of stations pending an inactivity
timeout. This leads to the wrong hapd context (one where the station had
already disassociated) being used in some cases (if the current/active
bss entry appears in the list after one where the station has just
disassociated from) for EAPOL processing.
Fix this by checking the WLAN_STA_ASSOC flag before assuming the right

A station may move from EAP/WPS key_mgmt to PSK using re-association. In
practice, this can happen most likely with WPS when the station runs
through the provisioning step (EAP/WPS) followed by PSK authentication.
If a deauthentication event is missed from the station for whatever
reason, the EAPOL authenticator state machine could have been left
running.
This can result in various issues, including unexpected disconnection of
the station while both the 4-way handshake and EAPOL authenticator state
machines (EAP) are running at the same time when the supplicant is
trying to use PSK. Fix this by explicitly clearing EAPOL authenticator
state machine on (re)association if the new association does not use it.

If the STA will then try to use the still valid PMKSA cache entry (or

state even though authSuccess was already forced to TRUE. This results
in the STA getting disconnected even though it should be allowed to

Number of places in hostapd use ap_sta_disconnect() instead of
ap_sta_disassociate() or ap_sta_deauthenticate(). There are some
differences between these functions, e.g., in the area how quickly

somewhat unexpected events since the EAPOL/WPA authenticator
