The regulatory rules in Japan do not allow OFDM to be used on channel
14. While this was to some extend assumed to be enforced by drivers
(many of which apparently don't), it is safer to make hostapd enforce
this by disabling any OFDM-related functionality. This tries to avoid
backwards compatibility issues by downgrading the mode rather than
rejecting the invalid configuration.

Add configuration of Spectrum Management subfield in the Capability
Information of Beacon, Probe Response, and Association Response frames.
Spectrum Management bit is set when directly requested by new
configuration option spectrum_mgmt_required=1 or when AP is running on
DFS channels. In the future, also TPC shall require this bit to be set.

Add Power Constraint information element to Beacon and Probe Response
frames when hostapd is configured on 5 GHz band and Country information
element is also added. According to IEEE Std 802.11-2012 a STA shall
determine a local maximum transmit power for the current channel based
on information derived from Country and Power Constraint elements.
In order to add Power Constraint element ieee80211d option need to be
enabled and new local_pwr_constraint config option need to be set to
unsigned value in units of decibels. For now this value is statically
configured but the future goal is to implement dynamic TPC algorithm
to control local power constraint.

The previous parser would have skipped a WFA vendor extension attribute
that includes only a single zero-length subelement. No such subelement
has been defined so far, so this does not really affect any
functionality, but better make the parser address this correctly should
such an element ever be added.

It looks like discovery_dev_id test case can still fail and based on the
previously added debug prints, this is happening since the P2P module
believes it is not in Listen state even when a P2P_LISTEN was issued.
p2p_listen_cb() did not get called on remain-on-channel event for some
reason, so lets add more debug to find out why this can happen.

Suppose we have multiple peers and we have peers advertising SD
capability, but no services registered for advertising. In this case,
even if there are multiple broadcast queries set, we might end up
sending only the lastly added broadcast query to the same device (since
SD_INFO won't get set for the first broadcast query). Add support for
multiple wildcard queries to be tracked to enable this type of use
case.
Some times it is seen that before advancing to next device in the list,
the scan results come and update SD_SCHEDULE flag. This will result in
sending the already sent query to the same device without giving chance
to other devices. This issue again is seen with peer devices advertising
SD capability without any services registered.

It is possible for an ER to send an unexpected PutWLANResponse action
when the destination STA is in disassociated, but not fully
deauthenticated state. sta->eapol_sm can be NULL in such state and as
such, it would be possible to hit a NULL pointer dereference in the
eapol_auth_eap_pending_cb() call at the end of the
hostapd_wps_probe_req_rx() when trying to proxy the WPS message to the
station. Fix this by validating that sta->eapol_sm is set before

This reverts commit 51e3eafb68. There are
too many deployed AAA servers that include both id-kp-clientAuth and
id-kp-serverAuth EKUs for this change to be acceptable as a generic rule
for AAA authentication server validation. OpenSSL enforces the policy of
not connecting if only id-kp-clientAuth is included. If a valid EKU is
listed with it, the connection needs to be accepted.

of an extra SAE confirm message being received after successful

The mechanism of using Status attribute in GO Negotiation Request was
used in some early specification drafts, but it is not compliant with
the current P2P specification where GO Negotiation Request is used only
for the purpose of initiating a new GO Negotiation. However, some
deployed devices use it to indicate rejection of GO Negotiation in a
case where they have sent out GO Negotiation Response with status 1. The
P2P specification explicitly disallows this.
To avoid unnecessary interoperability issues and extra frames, mark the
pending negotiation as failed and do not reply to this GO Negotiation
Request frame. Previously, GO Negotiation Response frame with status=4
was sent back as an indication of the GO Negotiation Request frame being
invalid. This response is not sent anymore and the status code for the
P2P-GO-NEG-FAILURE event is changed from 4 (invalid parameters) to 11
(rejected by user) for this specific workaround case.

If the peer device has already acknowledge receipt of the Invitation
Request frame, it is better not to re-start invitation by sending
another Invitation Request. This should not be needed since the peer
already has received the Invitation Request frame and sending the second
round in this type of sequence can cause issues with nl80211 offloaded
offchannel TX operations since driver_nl80211.c will lose the cookie
value for the first pending Action frame and may not be able to cancel
offchannel wait for it properly. this has been seen to trigger a failure
in the p2p_go_invite_auth test case with the scan failing due to GO
sending out Probe Response frame on incorrect channel (the channel used
in that not-cancelled Action TX).

Commit bd3a373767 added a mechanism to use
AP Channel attribute from within a Credential attribute to optimize
scans. However, this design is not actually used with the WPS NFC use
cases. With configuration token, the AP Channel attribute is in the same
container with the Credential attribute (and that was also handled in
the previous implementation). With connection handover, AP Channel
information is outside the Credential attribute as well.
Simplify implementation by removing the AP Channel within Credential
case. This allows wpas_wps_use_cred() to get the AP Channel from the
container instead of having to find this during credential iteration.
