Linux 2.6.32 (December 2009) introduced alternate netlink messages
for setting and installing keys, deprecating the older ones.
To allow hostapd/wpa_supplicant to use new features only provided via
the new API this patch migrates all netlink messages to the current ones.
Since the nl80211 driver was sometimes already using the new format this
is only unifying the netlink API usage and not changing the minimal
kernel requirement.
The following netlink attributes have been retired for key installs:
NL80211_ATTR_KEY_DATA
NL80211_ATTR_KEY_TYPE
NL80211_ATTR_KEY_SEQ
NL80211_ATTR_KEY_IDX
NL80211_ATTR_KEY_CIPHER
NL80211_ATTR_KEY_DEFAULT
NL80211_ATTR_KEY_DEFAULT_MGMT
NL80211_ATTR_KEY_DEFAULT_TYPES
And replaced by the following attributes nested in NL80211_ATTR_KEY:
NL80211_KEY_DATA
NL80211_KEY_TYPE
NL80211_KEY_SEQ
NL80211_KEY_IDX
NL80211_KEY_CIPHER
NL80211_KEY_DEFAULT
NL80211_KEY_DEFAULT_MGMT
NL80211_KEY_DEFAULT_TYPES
When getting Michael MIC failure notifications or querying a key
sequence number the kernel continues to use the old attributes:
NL80211_ATTR_KEY_TYPE
NL80211_ATTR_KEY_SEQ
NL80211_ATTR_KEY_IDX

PTKINITNEGOTIATING in the WPA state machine calls wpa_send_eapol() and
hands over the GTK instead of the PTK keyid.
Besides a confusing debug message this does not have any negative side
effects: The variable is only set to a wrong value when using WPA2 but
then it's not used.
With this patch PTKINITNEGOTIATING sets the PTK keyid unconditionally to
zero for EAPOL-Key msg 3/4 and differentiates more obviously between GTK
and PTK keyids.

When we set "channel=0" in hostapd.conf to enable ACS function, and set
a wrong channel list, e.g., chanlist=222-999 on purpose, hostapd would
still start ACS process to compute the ideal channel, even when there
are no available channels with such configuration.
Though there is no problem since hostapd fails to initialize interface,
it spends time going through the scan and the debug log entries may make
it more difficult to tell what was behind the failure.
Thus, check if there are any available channels in acs_request_scan(),
and return -1 if no available channel, then it will fail at acs_init(),
without doing ACS computation. It will show the following in the log:
Could not select hw_mode and channel. (-3)
wlan0: interface state UNINITIALIZED->DISABLED
Then we can know the setting is incorrect already in
hostapd_select_hw_mode(), instead of waiting for scan callback function
to know if the setting is ok for ACS or not. This can save time and help
to tell if the setting is correct at the initial function at the first.
This will also allow the ENABLE control interface command to return FAIL
when adding an interface dynamically.

A new argument to the DPP_AUTH_INIT command (conn_status=1) can now be
used to set Configurator to request a station Enrollee to report
connection result after a successfully completed provisioning step. If
the peer supports this, the DPP-CONF-SENT event indicates this with a
new argument (wait_conn_status=1) and the Configurator remains waiting
for the connection result for up to 16 seconds.
Once the Enrollee reports the result, a new DPP-CONN-STATUS-RESULT event
is generated with arguments result, ssid, and channel_list indicating
what the Enrollee reported. result=0 means success while non-zero codes
are for various error cases as specified in the DPP tech spec. If no
report is received from the Enrollee, the event with "timeout" argument
is generated locally.

Do not process any received Management frames with unexpected/invalid SA
so that we do not add any state for unexpected STA addresses or end up
sending out frames to unexpected destination. This prevents unexpected
sequences where an unprotected frame might end up causing the AP to send
out a response to another device and that other device processing the
unexpected response.
In particular, this prevents some potential denial of service cases
where the unexpected response frame from the AP might result in a

IEEE Std 802.11-2016 is not exactly clear on the encoding of the bit
string that is needed for KCK, PMK, and PMKID derivation, but it seems
to make most sense to encode the (commit-scalar + peer-commit-scalar)
mod r part as a bit string by zero padding it from left to the length of
the order (in full octets).
The previous implementation used the length of the prime (in full
octets). This would work for KCK/PMK, but this results in deriving all
zero PMKIDs for the groups where the size of the order is smaller than
the size of the prime. This is the case for groups 22, 23, and 24.
However, those groups have been marked as being unsuitable for use with
SAE, so this fix should not really have a practical impact anymore.
Anyway, better fix it and document this clearly in the implementation
taken into account the unclarity of the standard in this area.

The new hostapd configuration option eap_sim_id can now be used to

If the EAP-SIM/AKA server does not provide a new pseudonym and the
locally configured "pseudonym" in anonymous_identity is actually an
anonymous identitity instead of a real EAP-SIM/AKA pseudonym, do not
clear the anonymous_identity network profile parameter. This is needed
to avoid forgetting the anonymous identity when going through

Previously, check for local MI,MN in a peer's Peers List accepted only
the cases that include the last used MN from an MKPDU sent by the local
device. This was problematic since it was possible to synchronize MKPDU
transmission between two devices in a way that made them always miss the
last MKPDU from the other device before filling in the Peers List.
Relax this matching requirement of "acceptably recent MN" to mean both
the last used MN and the one used just before it (i.e., copied from
either of the last two MKPDUs sent by the local device) are accepted.
While this might help in some real world scenarios in making the
protocol converge more quickly, the main help from this is to fix
consistent hwsim test cases failures in macsec_psk_ns when using UML
with time travel option which happened to practically guarantee the
inconvenient timing of MKPDU transmission/reception that ended up with
the MKPDU processing to see MI,MN with MN being the last used MN minus

RFC 7170 has number of conflicting statements and missing details to

This does not yet support use of NewSessionTicket message to deliver a
new PAC (either in the server or peer implementation). In other words,
only the in-tunnel distribution of PAC-Opaque is supported for now. Use

an errata with text explaining how to derive it during fast
reauthentication.
This patch now exports the Session-Id for EAP-SIM during fast
reauthentication based on this Session-Id = 0x12 || NONCE_S || MAC
construction.

The rcons[] and Td4s[] array values need to be type cast explicitly to
u32 for the left shift 24 operation to be defined due to the implicit
conversion to int not handling the case where MSB would become 1 without

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.

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.

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.

In practice, some APs have interop issues with the DUT. This sub command
is used to transfer the AP info between the driver and user space. This
works both as a command and event. As a command, it configures the
stored list of APs from user space to firmware; as an event, it
indicates the AP info detected by the firmware to user space for
persistent storage. The attributes defined in enum
qca_vendor_attr_interop_issues_ap are used to deliver the parameters.

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.

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.

Commit 373c796948 ("OpenSSL: Fix compile with OpenSSL 1.1.0 and

versions of OpenSSL, asserting that it should happen automatically.
That appears not to be the case, and loading engines now fails because
the dynamic engine isn't present.
Fix it by calling ENGINE_load_builtin_engines(), which works for all
versions of OpenSSL. Also remove the call to ERR_load_ENGINE_strings()
because that should have happened when SSL_load_error_strings() is
called anyway.

It is apparently possible to somehow trigger the driver to report a
channel switch event during ACS operation when the interface information
is not yet complete. hapd->iface->current_mode could be NULL in that
case and that would result in process termination due to NULL pointer
dereference.
It should not really be possible to trigger a channel switch during ACS
is running (i.e., before the AP mode operation has been started), but
since that has been seen in an arbitrary test sequence with interface
start/stop operations with various parameters (both valid and invalid),
better prevent a crash here by ignoring the unexpected event instead of
trying to process it.
