Stop AP command can be used by the driver as an event to indicate that
AP mode has stopped operation. WLAN driver may have encountered errors
that has forced the driver to report this event or concurrent operations
on virtual interfaces may have forced AP operation to be stopped. When

A transmission failure of the TDLS Setup Request frame (TPK Handshake
M1) results in no further retries and the peer entry being left in state
where all TDLS Setup Request frames from the peer with higher address
would be rejected, thus always resulting in a failure to establish a
TDLS link. Handle the failures in transmission by disabling the link
immediately to ensure the traffic to the peer goes through the AP. This
commit also handles similar transmision failures for TPK Handshake M2
and M3 frames (TDLS Setup Response and Confirm).

The nl80211 command for setting the TX index does not distinguish TDLS

Previously, there could be two disconnection events in core

disconnection with a driver that implements SME internally. This could
result in undesired behavior when a disconnection is followed by a new

during fast reassoc or WPS provisioning). Avoid such issues by ignoring
locally generated disconnect events after requesting cfg80211 to
disconnect.

When using OpenSSL with TLS-based EAP methods, wpa_supplicant can now be

hostapd as EAP server can be configured to return cached OCSP response

for updating the response data (e.g., "openssl ocsp ..." command).
This allows wpa_supplicant to verify that the server certificate has not

actual data connection has been established (i.e., when a CRL could not

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:

My APs generate their configuration on their own using a different

be easier, if the hostapd configuration file would not depend on those
simple vlan_file files.
This patch removes the need for those one-line files by using the
<device>.<vlan> naming scheme if no vlan_file is given (or that file is
empty). This should not break any existing setup, as using dynamic_vlan

Commit fb8984fd6f added a mechanism to
skip the Listen state when the peer is expected to be waiting for us to

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

If an implicit TDLS set up request is obtained on an existing link or an

disables the existing link on a new set up request. Also,
wpa_tdls_reneg() function was invoking wpa_tdls_start() on an already
existing peer for the case of internal setup, which is incorrect. Thus
the invocation of wpa_tdls_start() is removed in wpa_tdls_reneg() and

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

SME/MLME. Fix this by adding a separate callback registration for the

Each GO Negotiation Request is (re)tried with an unique dialog token and
a GO Negotiation Response / Confirmation from the peer with a mismatched
dialog token is ignored which could result in a failure in this group
formation attempt. Thus, the P2P device would continue retrying the GO
Negotiation Request frames till the GO Negotiation Response frame with a
matching dialog token is received. To avoid the failures due to the
dialog token mismatch in retry cases if the peer is too slow to reply
within the timeout, the same dialog token value is used for every retry
in the same group formation handshake.
It should be noted that this can result in different contents of the GO
Negotiation Request frame being sent with the same dialog token value
since the tie breaker bit in GO Intent is still toggled for each
attempt. The specification is not very clear on what would be the
correct behavior here. Tie breaker bit is not updated on
"retransmissions", but that is more likely referring to the layer 2
retransmission and not the retry at higher layer using a new MMPDU.

Change the nl80211 driver in wpa_supplicant to correctly handle
connecting to a new AP through cfg80211 without SME capability. As
before, the driver will disconnect from the previously associated AP,
but now we attempt to immediately connect to our intended AP. This
prevents us from blacklisting the AP we were trying to connect to
because of a semantic mismatch between cfg80211 and wpa_supplicant. The
disconnect/connect patch generates a local disconnect nl80211 event
which we discard because we're already correctly tracking the pending
association request.
In detail:
cfg80211 does not support connecting to a new BSS while already
connected to another BSS, if the underlying driver doesn't support
separate authenticate and associate commands. wpa_supplicant is written
to expect that this is a supported operation, except for a little error
handling that disconnects from the current BSS when roaming fails and
relies on autoconnect logic to reconnect later. However, this failure to
connect is incorrectly attributed to the new AP we attempted to
associate with, rather than a local condition in cfg80211.
The combined effect of these two conditions is that full-mac drivers
accessible through cfg80211 but without SME capability take a long time
to roam across BSS's because wpa_supplicant will:
1) Fail to associate for local reasons
2) Disconnect and return that the association request failed
3) Blacklist the association target (incorrectly)
4) Do a scan
5) Pick a less desirable AP to associate with

Even though the standard currently describes disassociation to be used
for RSN element mismatch between Beacon/Probe Response frames and
EAPOL-Key msg 3/4, this is unnecessary difference from other cases that
deauthenticate. In addition, there is no point in leaving the 802.11
Authentication in place in this case. To keep things simpler, use
deauthentication here to get rid of the only use of
wpa_sm_disassociate().

If WPS Registrar tries to provision a WPA/WPA2-Personal network without
including a valid Network Key, the network block cannot be used to
connect to the network. Reject such credential without adding the
network block. This makes wpa_supplicant send WSC_NACK as a response to
the invalid Credential and stop the provisioning process immediately
rather than only after trying unsuccessfully to connect to the network.

The new P2P_SET parameter disc_int can now be used to configure
discoverable interval for p2p_find operations. The format of the command
for setting the values is "P2P_SET disc_int <minDiscoverableInterval>
<maxDiscoverableInterval> <max TUs for discoverable interval>". The
first two parameters are given in units of 100 TUs (102.4 ms). The third
parameter can be used to further limit the interval into a specific TU
amount. If it is set to -1, no such additional limitation is enforced.
It should be noted that the P2P specification describes the random
Listen state interval to be in units of 100 TUs, so setting the max TU
value to anything else than -1 is not compliant with the specification
and should not be used in normal cases. The default parameters can be
set with "P2P_SET disc_int 1 3 -1".

The old WPS interface for using NFC has no known deployments and even
the binary libraries referenced here are not easily available anymore.
Since the new interface for using NFC with WPS covers the same
functionality, remove the old implementation to clean up WPS
implementation.

When WPS is used with NFC connection handover, the AP may indicate its
operating channel within the credential information. Use this
informatiom, if present, to speed up the scan process.

This commit adds new wpa_supplicant ctrl_iface commands to allow
external programs to go through NFC connection handover mechanism
with wpa_supplicant taking care of the WPS processing. This version
includes only the case where wpa_supplicant is operating as a
station/Enrollee.

The previous eapol_sm_notify_cached() implementation forced the port
to be authorized when receiving EAPOL-Key msg 1/4 that included a
matching PMKID in cases when PMKSA caching is used. This is too early
since the port should really be authorized only after the PTK has been
configured which is the case when PMKSA caching is not used.
Fix this by using the EAPOL supplicant PAE state machine to go through
the AUTHENTICATING and AUTHENTICATED states instead of forcing a jump
to AUTHENTICATED without performing full state machine steps. This can
be achieved simply by marking eapSuccess TRUE at least with the current
version of EAP and EAPOL state machines (the earlier commits in this
function seemed to indicate that this may have not been that easy in
the older versions due to the hacks needed here).
This addresses an issue with nl80211-based driver interface when the
driver depends on the STA Authorized flag being used to prevent
unprotected frames from being accepted (both TX and RX) prior to PTK
configuration.

If the driver indicates support for multi-channel concurrency, change
the p2p_connect behavior to not force the current operating channel, but
instead, just mark it as preferred for GO Negotiation. This change
applies only for the case when the freq parameter is not used with the
p2p_connect command.

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
hapd context was found for the given station.

P2P includes two use cases where one of the devices is going to start a
group and likely change channels immediately after processing a frame.
This operation may be fast enough to make the device leave the current
channel before the peer has completed layer 2 retransmission of the
frame in case the ctrl::ack frame was lost. This can result in the peer
not getting TX status success notification.
For GO Negotiation Confirm frame, p2p_go_neg_conf_cb() has a workaround
that ignores the TX status failure and will continue with the group
formation with the assumption that the peer actually received the frame
even though we did not receive ctrl::ack. For Invitation Response frame
to re-invoke a persistent group, no such workaround is used in
p2p_invitation_resp_cb(). Consequently, TX status failure due to lost
ctrl::ack frame results in one of the peers not starting the group.
Increase the likelihood of layer 2 retransmission getting acknowledged
and ctrl::ack being received by waiting a short duration after having
processed the GO Negotiation Confirm and Invitation Response frames for
the re-invocation case. For the former, use 20 ms wait since this case
has been worked around in deployed devices. For the latter, use 50 ms
wait to get even higher likelihood of getting ctrl::ack through since
deployed devices (and the current wpa_supplicant implementation) do not
have a workaround to ignore TX status failure.
20 ms is long enough to include at least couple of retries and that
should increase likelihood of getting ctrl::ack through quite a bit. The
longer 50 ms wait is likely to include full set of layer 2 retries.

Previously, WPS Registrar allowed multiple wildcard PINs to be
configured. This can get confusing since these PINs get assigned to any
Enrollee that does not have a specific PIN and as such, cannot really be
used with different PIN values in reasonable ways. To avoid confusion
with multiple enabled PINs, invalidate any previously configured
wildcard PIN whenever adding a new one.

While the existing code already addresses TLS Message Length validation
for both EAP-TLS peer and server side, this adds explicit checks and
rejection of invalid messages in the functions handling reassembly. This
does not change externally observable behavior in case of EAP server.
For EAP peer, this starts rejecting invalid messages instead of
addressing them by reallocating the buffer (i.e., ignoring TLS Message
Length in practice).
Signed-hostap: Jouni Malinen <j@w1.fi>
EAP-TLS/PEAP/TTLS/FAST server implementation did not validate TLS
Message Length value properly and could end up trying to store more
information into the message buffer than the allocated size if the first
fragment is longer than the indicated size. This could result in hostapd
process terminating in wpabuf length validation. Fix this by rejecting
messages that have invalid TLS Message Length value.
This would affect cases that use the internal EAP authentication server
in hostapd either directly with IEEE 802.1X or when using hostapd as a
RADIUS authentication server and when receiving an incorrectly
constructed EAP-TLS message. Cases where hostapd uses an external
authentication are not affected.
