0de46d8a66 mesh: Fix RSN initialization failure handling
The driver was left in mesh mode (joined to the group) if RSN
authenticator initialization failed. This could result in next
operations failing due to unexpected driver state.

This was found with the following hwsim test case sequence:
mesh_wpa_auth_init_oom dpp_config_no_discovery

f82a840878 tests: Fix ERP test cases to close separate AS (ifname=as-erp)
The earlier change from using apdev[1] to using a no-interface
ifname=as-erp in the ERP related test cases ended up leaving the
separate authentication server interface running after the end of the
test case. This left UDP port 18128 open and any consecutive test case
needing this port failed to start another authentication server.

This can be reproduced with following test case sequence:

The Session-Id derivation for EAP-AKA in RFC 5247 only explained how the
Session-Id is derived for regular authentication. Jouni reported it as
an errata with text explaining how to derive it during fast

This patch now exports the Session-Id for EAP-AKA during fast

b1aee7a622 DPP: Fix bootstrapping URI parser to handle channel list for an opclass
The bootstrapping URI format for DPP was extended during protocol design
to allow a list of channels without having to repeat the same operating
class information for each channel. That change was not included in the
initial implementation of the parser and a channel-list like
"C:81/1,6,11" would not be understood correctly (i.e., only the longer
"C:81/1,81/6,81/11" form would have been parsed correctly).

Fix this by extending the parser to accept both the shorter and longer
form for a list of channels within a single operating class.

69afb6b395 FILS: Verify RSNE match between Beacon/Probe Response and (Re)AssocResp
IEEE Std 802.11ai-2016 requires the FILS STA to do this check, but this
was missing from the initial implementation. The AP side behavior was
not described properly in 802.11ai due to a missing change in the
(Re)Association Response frame format tables which has resulted in some
deployed devices not including the RSNE.

For now, use an interoperability workaround to ignore the missing RSNE
and only check the payload of the element if it is present in the
protected frame. In other words, enforce this validation step only with
an AP that implements FILS authentication as described in REVmd while
allowing older implementations to skip this check (and the protection
against downgrade attacks). This workaround may be removed in the future
if it is determined that most deployed APs can be upgraded to add RSNE
into the (Re)Association Response frames.

831d8c9cf5 FILS: Add RSNE into (Re)Association Response frame
This AP behavior was missing from IEEE Std 802.11ai-2016, but it is
needed for the RSNE validation to work correctly and for a FILS STA to
be able to perform the mandatory check for RSNE matching when processing
the (Re)Association Response frame (as described in 802.11ai). REVmd
will be updating the standard to cover this AP case, so prepare the
implementation to match that. Without this, a FILS STA might reject
association whenever using FILS authentication.

ae21cffb2c Add QCA vendor command to support beacon reporting feature
Add a QCA vendor sub command QCA_NL80211_VENDOR_SUBCMD_BEACON_REPORTING
to implement beacon reporting feature. Different operations required to
implement this feature can be specified in
QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_OP_TYPE.

Userspace requests the driver/firmware to periodically report received
Beacon frames whose BSSID matches the current connected BSS's MAC
address. If userspace requests the driver/firmware to send beacon
reports actively, the driver encapsulates the details of the beacon in
an event and sends it to userspace asynchronously. Otherwise, the driver
will only update the beacon in cfg80211 scan cache but will not send any
event to userspace.

If this command is not issued, the current behavior of the
driver/firmware is to update the cfg80211 scan cache only when there is
a scan issued by the host in progress or whenever there is a change in
IEs of the Beacon frames from the current connected BSS.

The userspace requests the driver/firmware to stop reporting beacons
when reporting is not required anymore. If the driver/firmware is not
able to receive Beacon frames because of other Wi-Fi operations such as
off-channel activities, etc., the driver/firmware sends a pause event to
userspace and stops reporting Beacon frames. The driver/firmware
indicates whether the beacon reporting automatically resumes later by
using the QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_AUTO_RESUMES flag. If
userspace doesn't want the beacon reporting to be resumed automatically,
userspace can send QCA_WLAN_VENDOR_BEACON_REPORTING_OP_STOP command to
the driver to stop beacon reporting.

ef7217518b hostapd: Add airtime policy configuration support
This adds support to hostapd for configuring airtime policy settings for
stations as they connect to the access point. This is the userspace
component of the airtime policy enforcement system PoliFi described in
this paper: https://arxiv.org/abs/1902.03439

The Linux kernel part has been merged into mac80211 for the 5.1 dev
cycle.

The configuration mechanism has three modes: Static, dynamic and limit.
In static mode, weights can be set in the configuration file for
individual MAC addresses, which will be applied when the configured
stations connect.

In dynamic mode, weights are instead set per BSS, which will be scaled
by the number of active stations on that BSS, achieving the desired
aggregate weighing between the configured BSSes. Limit mode works like
dynamic mode, except that any BSS *not* marked as 'limited' is allowed
to exceed its configured share if a per-station fairness share would
assign more airtime to that BSS. See the paper for details on these
modes.
