Change the maximum retry limit from 10 to 120 to match the behavior
used with GO Negotiation Request frames when trying to start GO
Negotiation with a peer that does not acknowledge frames (e.g., due

Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
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

It should be noted that the P2P specification describes the random

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

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.

Use the NL80211_IFACE_COMB_NUM_CHANNELS value > 1 as a trigger for
enabling support for P2P multichannel channel concurrency. This does not
handle all possible details of enforcing driver capabilities, but it is
a good first step for allowing nl80211 drivers to enable multichannel
concurrency.

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

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.

The previous implementation was able to re-open the connection to an
external program (e.g., hlr_auc_gw) when needed, but required the
connection to be available during startup. Extend this to allow the
initial failure, so that hlr_auc_gw can be started after hostapd.

Some deployed authentication servers seem to be unable to handle the TLS
Session Ticket extension (they are supposed to ignore unrecognized TLS
extensions, but end up rejecting the ClientHello instead). As a
workaround, disable use of TLS Sesson Ticket extension for EAP-TLS,
EAP-PEAP, and EAP-TTLS (EAP-FAST uses session ticket, so any server that
supports EAP-FAST does not need this workaround).

tls_disable_session_ticket=1 in phase1/phase2 can now be used to disable
