The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."
When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.
Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

Delay Protect and Replay Protect are two separate and distinct features
of MKA. Per IEEE Std 802.1X-2010, 9.10.1 "Delay Protect, TRUE if LPNs
are being reported sufficiently frequently to allow the recipient to
provide data delay protection. If FALSE, the LPN can be reported as
zero", and per 9.10 "NOTE--Enforcement of bounded received delay
necessitates transmission of MKPDUs at frequent (0.5 s) intervals, to
meet a maximum data delay of 2 s while minimizing connectivity
interruption due to the possibility of lost or delayed MKPDUs."
This means struct ieee802_1x_mka_sak_use_body::delay_protect should only
be set TRUE when MKPDUs are being transmitted every 0.5 s (or faster).
By default the KaY sends MKPDUs every MKA_HELLO_TIME (2.0 s), so by
default delay_protect should be FALSE.
Add a new 'u32 mka_hello_time' parameter to struct ieee802_1x_kay. If
delay protection is desired, the KaY initialization code should set
kay->mka_hello_time to MKA_BOUNDED_HELLO_TIME (500 ms).

Commit 7b4d546e ("wpa_supplicant: Add macsec_integ_only setting for
MKA") introduced policy setting SHOULD_ENCRYPT (MACsec provides
integrity+confidentiality) in addition to SHOULD_SECURE (MACsec provides
integrity only). In both cases the KaY is populating the
"Confidentiality Offset" parameter within the "Distributed SAK parameter
set" with CONFIDENTIALITY_OFFSET_0=1. In the case of SHOULD_SECURE the
parameter should be populated with CONFIDENTIALITY_NONE=0.
IEEE Std 802.1X-2010, Table 11-6 and Figure 11-11 define how the two
Confidentiality Offset bits in the "Distributed SAK parameter set" must
be set: "0 if confidentiality not used" and "1 if confidentiality with
no offset". When policy is SHOULD_SECURE KaY should to send the former,
and when policy is SHOULD_ENCRYPT KaY should send the latter.

This new QCA vendor command is used to query the supported AKM suite

from the driver and thus the current user space has to assume the driver
to support all the AKMs. This may be the case with some drivers (e.g.,
mac80211-based ones) but there are cfg80211-based drivers that implement
SME and have constraints on which AKMs can be supported (e.g., such
drivers may need an update to support SAE AKM using
NL80211_CMD_EXTERNAL_AUTH). Allow such drivers to specify the exact set
of supported AKMs so that user space tools can determine what network
profile options should be allowed to be configured. This command returns
the list of supported AKM suite selectors in the attribute

Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.
On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.
Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.
As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

It is better not to process a new (most likely repeated) FILS HLP
request if a station retransmits (Re)Association Request frame before
the previous HLP response has either been received or timed out. The
previous implementation ended up doing this and also ended up
rescheduling the fils_hlp_timeout timer in a manner that prevented the
initial timeout from being reached if the STA continued retransmitting
the frame. This could result in failed association due to a timeout on
the station side.
Make this more robust by processing (and relaying to the server) the HLP
request once and then ignoring any new HLP request while the response
for the relayed request is still pending. The new (Re)Association
Request frames are otherwise processed, but they do not result in actual
state change on the AP side before the HLP process from the first
pending request is completed.

Add interface for drivers to report changes in TX/RX throughput
dynamically to user space. This information can be used by userspace

throughput. The driver may optionally provide guidance on which TCP
parameters to be configured for optimal performance along with the

The TCP parameters that need to be tuned for peak performance are not
interface specific. Based on the guidance from the driver and
considering the other interfaces that may be affected with the new
configurations, a userspace tool has to choose the values to be
configured for these parameters to achieve optimal performance across
interfaces.
The throughput levels informed by the driver with this event are only
for providing guidance on TCP parameter tuning from userspace. The
driver may change the thresholds used to decide low or medium or high
throughput levels based on several parameters based on the PHY layer
capacity in the current connection, the number of packets being
dispatched per second, or the number of packets pending in queues, etc.
The throughput levels may not be consistent with the actual throughput

For hostapd/AP, this mechanism is enabled by setting

created.
Unfortunately the fopen(3) function does not provide such a facility, so
the approach needs to be changed in the following way:
1) The file descriptor needs to be created manually using the open(3)
function with the correct flags and the desired mode set.
2) fdopen(3) can then be used on the file descriptor to associate a file
stream with it.
Note: This modification will not change the file permissions of any
already existing debug log files, and only applies to newly created
ones.

When moving a 5 GHz VHT AP to 2.4 GHz band with VHT disabled through the
hostapd control interface DISABLE/reconfig/ENABLE commands, enabling of
the AP on 2.4 GHz failed due to the previously configured VHT capability
being compared with hardware VHT capability on 2.4 GHz band:
hw vht capab: 0x0, conf vht capab: 0x33800132
Configured VHT capability [VHT_CAP_MAX_MPDU_LENGTH_MASK] exceeds max value supported by the driver (2 > 0)
ap: interface state DISABLED->DISABLED
Since VHT (ieee80211ac) config is already disabled for the 2.4 GHz band,
add fix this by validating vht_capab only when VHT is enabled.

Previous implementation ended up triggering PMF check for previous
association and SA Query procedure incorrectly in cases where there is a
STA entry in hostapd, but that STA is not in associated state. This
resulted in undesired temporary rejection of the association with status
code 30.
This ended up breaking OWE group negotiation when PMF is in use since
the check for the OWE group would have happened only after this earlier
PMF check and rejection (i.e., the station got status code 30 instead of
the expected 77).
For example, when the AP is configured with OWE group 21 and a station
tries groups 19, 20, and 21 (in this sequence), the first two
Association Request frames should be rejected with status code 77.
However, only the first one got that status code while the second one
got status code 30 due to that issue with PMF existing association
check.
Furthermore, hostapd was continuing with SA Query procedure with
unencrypted Action frames in this type of case even though there was no
existing association (and obviously, not an encryption key either).
Fix this by checking that the STA entry is in associated state before
initiating SA Query procedure based on the PMF rules.

When Probe Request frame handling was extended to use MAC ACL through
ieee802_11_allowed_address(), the MSG_INFO level log print ("Station
<addr> not allowed to authenticate") from that function ended up getting
printed even for Probe Request frames. That was not by design and it can
result in excessive logging and MSG_INFO level if MAC ACL is used.
Fix this by printing this log entry only for authentication and
association frames. In addition, drop the priority of that log entry to
MSG_DEBUG since this is not really an unexpected behavior in most MAC
ACL use cases.

PMKID derivation with the Suite B AKMs is a special case compared to
other AKMs since that derivation uses KCK instead of PMK as an input.
This means that the PMKSA cache entry can be added only after KCK has
been derived during 4-way handshake. This also means that PMKID would
change every time 4-way handshake is repeated even when maintaining the
same PMK (i.e., during PTK rekeying and new associations even if they
use PMKSA caching).
wpa_supplicant was previously replacing the PMKSA cache entry whenever a
new PMKID was derived. This did not match hostapd expectations on the AP
side since hostapd did not update the PMKSA cache entry after it was
created. Consequently, PMKSA caching could be used only once (assuming
no PTK rekeying happened before that). Fix this by making wpa_supplicant
behave consistently with hostapd, i.e., by adding the Suite B PMKSA
cache entries with the PMKID from the very first 4-way handshake
following PMK derivation and then not updating the PMKID.
IEEE Std 802.11-2016 is somewhat vague in this area and it seems to
allow both cases to be used (initial PMKID or any consecutive PMKID
derived from the same PMK). While both cases could be supported that
would result in significantly more complex implementation and need to
store multiple PMKID values. It looks better to clarify the standard to
explicitly note that only the first PMKID derived after PMK derivation
is used (i.e., match the existing hostapd implementation).

Commit 3f53c006c7 ('nl80211: Ignore
disconnect event in case of locally generated request') made
wpa_supplicant ignore the next received disconnect event for cases where
wpa_supplicant itself requested a disconnection. This can result in
ignoring a disconnection notification in some cases.
Considering a P2P Client receiving disconnect event from the kernel
after a P2P group is started, drv->ignore_next_local_disconnect is
cleared to 0, then wpa_driver_nl80211_disconnect() will be called during
the removal of the group, in which drv->ignore_next_local_disconnect is
set to 1 by mistake.
Do not allow ignore_next_local_{disconnect,deauth} to be set to 1 if the
driver is not in associated state (drv->associated is 0) to avoid this
type of cases.
