It is possible for the driver to indicate multiple Probe Request frames
that would be processed in a single loop. If those frames happen to be
from a peer which with we are trying to start GO Negotiation, multiple
timeouts to start GO Negotiation (p2p_go_neg_start) could end up being
scheduled. This would result in confusing burst of multiple GO
Negotiation Request frames being sent once the RX loop finally
concludes. Avoid this by scheduling only a single eloop timeout to
trigger GO Negotiation regardless of how many Probe Request frames from
the peer is received. In addition, make sure this timeout gets canceled
in p2p_deinit().

If we have already sent out GO Negotiation Response and are waiting for
the peer to reply with GO Negotiation Confirm, there is no point in
re-starting GO Negotiation based on Probe Request frame from the peer.

The device that is selected as the GO shall incode P2P Group ID
attribute in GO Negotiation Response/Confirm message. Previously we did
not reject a message without that attribute since it was possible to
continue operations even without knowing the SSID. However, this can
potentially result in confusing results since missing P2P Group ID
attribute can be a sign of conflicting GO role determination (both
devices assuming the peer is the GO). To get clearer end result for the
GO Negotiation, reject this as a fatal error. In addition, stop GO
Negotiation if GO Negotiation Confirm indicates non-zero status since
that is also a fatal error.

Commit 624b4d5a64 changed GO Negotiation
to use the same Dialog Token value for all retransmissions of the GO
Negotiation Request within the same session. However, it did leave the
tie breaker bit changing for each frame. While this should not have
caused issues for most cases, it looks like there are possible sequences
where the peer may end up replying to two GO Negotiation Request frames
with different tie breaker values. If in such a case the different GO
Negotiation Response frames are used at each device, GO role
determination may result in conflicting results when same GO intent is
used.
Fix this by assigning the tie breaker value at the same time with the
dialog token (i.e., when processing the p2p_connect command instead of
for each transmitted GO Negotiation Request frame) to avoid issues with
GO selection.

The driver may have cached (e.g., in cfg80211 BSS table) the scan
results for relatively long time. To avoid reporting stale information,
update P2P peers only based on results that have based on frames
received after the last p2p_find operation was started.
This helps especially in detecting when a previously operating GO stops
the group since the BSS entry for that could live for 30 seconds in the
cfg80211 cache. Running p2p_flush followed by p2p_find will now allow
wpa_supplicant to not add a P2P peer entry for that GO if the group had
been terminated just before that p2p_flush command. Previously, that GO
could have been indicated as a newly found device for up to 30 seconds
after it had stopped the group.

For various P2P use cases, it is useful to have more accurate timestamp

If we discover a P2P peer based on a Beacon frame from the GO role, we

reporting of the P2P-DEVICE-FOUND event when this happens on one of 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

Expiry can always trigger a deauthentication, but otherwise,
deauthentication should only happen when the *current* cache entry is
removed and not being replaced. It should not happen when the current
PMK just happens to match the PMK of the entry being removed, since
multiple entries can have the same PMK when OKC is used and these
entries are often removed at different times.

The GO may be in sleep when we send a PD Request frame to indicate that
we are about to join a running group. Previously, this frame was not
retried more than normal low level retries. This can result in the GO
not getting the frame especially in cases where concurrent multi-channel
operations or aggressive sleep schedule is used since most drivers do
not yet synchronize with the GO's NoA before association.
Increase the likelihood of the GO receiving the PD Request frame by
retransmitting it similarly to the PD-for-GO-Negotiation case. Start
the actual join operation only after these retries have failed to get
an acknowledgment from the GO to give the connection attempt a chance
to succeed if the driver implements better NoA synchronization for it.

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

The previous eapol_sm_notify_cached() implementation forced the port

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

be achieved simply by marking eapSuccess TRUE at least with the current

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.

EAP-SIM/AKA reauth data into the database to allow this to persist
over hostapd restarts.

This allows hostapd to use an SQLite database for storing EAP-SIM/AKA
pseudonyms over process restarts. CONFIG_SQLITE=y build option adds
support for this and the SQLite database file is specified in eap_sib_db
configuration parameter.

This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.
This commit does not included changes to WPS or P2P to allow GCMP to be
used.

The new gas_request and gas_response_get commands can be used to request
arbitary GAS queries to be performed. These can be used with ANQP or
with other (including vendor specific) advertisement protocols.
gas_request <BSSID> <AdvProtoID> [Query]
gas_response_get <addr> <dialog token> [offset,length]
For example, ANQP query for Capability list in interactive wpa_cli
session:
> gas_request 02:00:00:00:01:00 00 000102000101
<3>GAS-RESPONSE-INFO addr=02:00:00:00:01:00 dialog_token=0

It should be noted that the maximum length of the response buffer is
currently 4096 bytes which allows about 2000 bytes of the response data
to be fetched with a single gas_response_get command. If the response is
longer, it can be fetched in pieces as shown in the example above.

Maintain state of WPS APs during iteration to find the correct AP for
WPS PIN operation when no specific BSSID is specified. This information
can be used for optimizing the order in which the APs are tried. This
commit is only adding the collection of the information and more

Commit 488f4a7108 configures a timer
before p2p_send_action(). This may result in the timer getting fired
earlier to the off channel transmission of the frame and thus another PD
request being retransmitted. This shall lead to the new PD request with
an incremented dialog token being transmitted. For the cases where the
later PD request might not be transmitted as the host driver is busy
transmitting the earlier frame, the received PD response could be
dropped for the dialog token mismatch. Remove the timer configuration to
avoid this behavior.

Previously, all station mode scan operations were either skipped or
delayed while any P2P operation was in progress. To make concurrent
operations easier to use, reduce this limitation by allowing a scan
operation to be completed in the middle of a p2p_find. In addition,
allow station mode association to be completed. When the station mode
operation is run to its completion (scan results not acted on,
connection to an AP completed, connection failed), resume the p2p_find
operation.

A new optional delay=<search delay in milliseconds> parameter can now be
used with p2p_find command to request an extra delay between search
iterations. This can be used, e.g., to make p2p_find friendlier to
concurrent operations by avoiding it from taking 100% of the radio
resources.

This EAP type uses a vendor specific expanded EAP header to encapsulate
EAP-TLS with a configuration where the EAP server does not authenticate
the EAP peer. In other words, this method includes only server
authentication. The peer is configured with only the ca_cert parameter
(similarly to other TLS-based EAP methods). This method can be used for
cases where the network provides free access to anyone, but use of RSN
with a securely derived unique PMK for each station is desired.
The expanded EAP header uses the hostapd/wpa_supplicant vendor
code 39068 and vendor type 1 to identify the UNAUTH-TLS method.
