Some driver wrappers may implement this by writing eight octets even
though IPN is only six octets. Use a separate WPA_KEY_RSC_LEN (8) octet
buffer in the call to make sure there is enough buffer room available
for the full returned value and then copy it to IPN field.
The previous implementation used the following igtk field as the extra

It is possible for the GO of a persistent group to change the PSK or

without the SSID changing (i.e., the group is still valid, but just not

In a AP/STA concurrent setup, if the STA interface is continually

is basically broken since beaconing would be erratic.
This option can be used in a WDS setup where one AP acts as a

Previously, there could be two disconnection events in core
wpa_supplicant when going through a case of wpa_supplicant-requested
disconnection with a driver that implements SME internally. This could
result in undesired behavior when a disconnection is followed by a new
connection attempt before the extra event has been received (e.g.,
during fast reassoc or WPS provisioning). Avoid such issues by ignoring
locally generated disconnect events after requesting cfg80211 to
disconnect.
This makes the previously used ignore_next_local_disconnect more
consistent by setting the variable within
wpa_driver_nl80211_disconnect() so that both callers get the same

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been revoked as part of the EAP-TLS/PEAP/TTLS/FAST handshake before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, 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

also be used to track any other device-has-been-created-by-hostapd

Commit c3fea27274 added a call to clear
all other PMKSA cache entries for the same network if the PMKSA cache
entry of the current AP changed. This was needed to fix OKC cases since
the other APs would likely use the new PMK in the future. However, this
ended up clearing entries in cases where that is not desired and this
resulted in needing additional full EAP authentication with networks
that did not support OKC if wpa_supplicant was configured to try to use
it.
Make PMKSA cache entry flushing more limited so that the other entries
are removed only if they used the old PMK that was replaced for the
current AP and only if that PMK had previously been used successfully
(i.e., opportunistic flag was already cleared back to 0 in

Commit fb8984fd6f added a mechanism to
skip the Listen state when the peer is expected to be waiting for us to
initiate a new GO Negotiation. However, this flag was set when building
the GO Negotiation Response frame with status 1 regardless of whether we
managed to send that frame or peer receive it. This could result in GO
Negotiation failures in cases where the peer did not receive the
response and Listen channels of the devices were different. Fix this by
setting the flag only after TX status indicating success has been
received.

make the wait-for-GO-Neg-Resp timeout random between 100 and 200 ms to

There is no need to have this check copied to each caller since this
needs to be done for every case when a new peer is being added.

Peer entries were getting added on every discover request from the peer,
thus resulting in multiple entries with the same MAC address. Ensures
that a check is done for the presence of the peer entry and reuse the
existing entry instead of adding a new one.

GAS server used the same public_action_cb mechanism as P2P to process
Action frames. This ended up overriding P2P processing of Action frames
while running an AP/GO interface with a build that enables Interworking
(e.g., for Hotspot 2.0) and a driver that uses hostapd for AP mode
SME/MLME. Fix this by adding a separate callback registration for the
GAS server. This should really be cleaned up by supporting arbitrary
number of callback handlers, but for now, this addresses the regression
with a minimal change.

Very basic support for OpenBSD. No support for scanning yet, so this needs
ap_scan=0 and expects that the user has configured the interface manually
using ifconfig(8).
