When I was testing dpp_auth_init on an AP with Enrollee on a different
channel from the AP I was getting failures. This happened on hwsim in
UML with time-travel for me. I don't recall seeing this with real
devices, presumably because of lax offchan implementation.
The DPP authentication would succeed. However the station would then try
to get configuration through a GAS request and fail.
The AP reported the following logs (grepped):
> 1614762426.860212: RX_ACTION category 4 action 10 sa 02:00:00:00:01:00 da 02:00:00:00:00:00 len 227 freq 2412

AP would still receive the GAS request on ch1 but would then try to
respond on ch11 while STA was waiting on ch1.

The Query Response Length field was missing from GAS Initial Response
and GAS Comeback Response frames in the DPP specific code path from
hostaps GAS server. This resulted in invalid frames being used when the
DPP Config Response needed fragmentation. Fix this by adding the Query

The new hostapd configuration parameter dpp_controller can now be used
with the following subparameter values: ipaddr=<IP address>
pkhash=<hexdump>. This adds a new Controller into the configuration
(i.e., more than one can be configured) and all incoming DPP exchanges
that match the specified Controller public key hash are relayed to the

Commit 941caed980 ('MBO: Add MBO
ANQP-element processing on AP') changed the design by using the
rx_anqp_vendor_specific() function to process all ANQP vendor specific
elements. However, the caller for this was within ifdef CONFIG_HS20
block. Fix this by calling the function even in CONFIG_HS20=y is not
included in the build. This fixes CONFIG_MBO=y builds without
CONFIG_HS20=y.

Previously, the temporary STA session timeout was set to 5 seconds. If
gas_comeback_delay is configured to be longer than 5 seconds, GAS
Comeback Response frame can't include queried information as all pending

The loop to add hash values was supposed to be limited to at most 10000

gas_address3=1 can now be used to force hostapd to use the IEEE 802.11
standards compliant Address 3 field value (Wildcard BSSID when not

BSSID).
Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies
that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS. hostapd used
to use the actual BSSID value for all such frames regardless of whether
the destination STA is a member of the BSS.
Fix this by using the wildcard BSSID in cases the destination STA is not
a member of the BSS. Leave group addressed case as-is (i.e., the actual
BSSID), since both values are accepted. No such frames are currently
used, though.
This version is still using the AP BSSID value in the Address 3 field
for GAS response frames when replying to a GAS request with AP BSSID
instead of Wildcard BSSID. This is left as a workaround to avoid
interoperability issues with deployed STA implementations that are still
using the non-compliant address and that might be unable to process the
standard compliant case.

The new hostapd configuration parameter anqp_elem can now be used to
configure arbitrary ANQP-elements for the GAS/ANQP server. In addition
to supporting new elements, this can be used to override previously
supported elements if some special values are needed (mainly for testing
purposes).
The parameter uses following format:
anqp_elem=<InfoID>:<hexdump of payload>
For example, AP Geospatial Location ANQP-element with unknown location:
anqp_elem=265:0000
and AP Civic Location ANQP-element with unknown location:
anqp_elem=266:000000

This avoids an issue where a wpa_supplicant build with CONFIG_P2P=y and

a GO and sending out two replies. Only the P2P SD implementation should

There seemed to be an off-by-one error in the validation of GAS request
frames. If a Public Action frame without the Action code field would
have reached this function, the length could have been passed as
(size_t) -1 which would likely have resulted in a crash due to reading
beyond the buffer. However, it looks like such frame would not be
delivered to hostapd at least with mac80211-based drivers. Anyway, this
function better be more careful with length validation should some other
driver end up reporting invalid Action frames.
In addition, the Action code field is in a fixed location, so the
IEEE80211_HDRLEN can be used here to clean up bounds checking to avoid
false reports from static analyzer.

When GAS is used with PMF negotiated, Protected Dual of Public Action
frames are expected to be used instead of Public Action frames, i.e.,
the GAS/ANQP frames are expected to be encrypted. Add support for this
different category of Action frames being used for GAS. The payload
after the Category field is identical, so the only change is in using
the Category field based on what was received in the request frames. For
backwards compatibility, do not enforce protected dual to be used on the
AP side, i.e., follow what the station does.

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.
