There is an issue when starting a non-MLD AP on the same interface that
previous operated as an AP MLD. When the previous AP MLD got stopped,
links were not removed when using hostapd. Next non-MLD AP will fail to
start because some nl80211 operations still require link id (e.g., set
freq).
Remove links when AP MLD is stop to avoid such issue. This was already
done in the deinit_ap() handler when using wpa_supplicant, but hostapd
needs to do same.

When processing a (Re)Association Request frame and no corresponding

address from the Basic ML element, as it is possible that the station
is trying to re-associate but with a different link address (in such

With nl80211 we need to supress the kernel generated event for any
disconnect and deauthenticate. This code is a bit fragile, as it
assumes that an event will happen. Commit b898b65582 ("nl80211: Do
not ignore disconnect event in case of !drv->associated") changed this
to only disconnect when the driver knows it is associated (apparently
required for P2P), however, deauthentication may also occur without
being associated yet.
Looking at the issue, what we are really interested in is whether the
event belongs to a disconnect/deauth command that we have send
ourselves. Any event happening after the disconnect/deauth completes
should not be suppressed (or after the next connect/auth as that would
be sufficient). We therefore need to know from the event stream
whether events were generated before or after disconnect/deauth
command completion.
To do so, send a simple command on the nl_event socket. As this will
be returned back to us in the correct order with regard to the events.
We can therefore use it to safely reset our internal
ignore_next_local_{deauth,disconnect} variables.

The max transmit power of Standard Power (SP) Access Points (AP) on
6 GHz band and APs on 2.4 GHz and 5 GHz bands is limited by effective
isotropic radiated power (EIRP), while the max transmit power of Low
Power Indoor (LPI) APs on 6 GHz Band is limited by power spectral
density (PSD). Therefore the max transmit power of LPI APs grows as the
channel width increases, similar to the noise power which has constant
PSD.
Adjust the SNR of BSSes based on the transmit power config and max
channel width. EIRP limited APs usually have constant max transmit power
on different channel widths, their SNR decreases on larger channel width
because the noise power is higher, while PSD limited APs have constant
SNR over all channel widths.

Wi-Fi Aware pairing responder needs to forward the derive PMK to the
framework on successful pairing setup. The framework will set
corresponding PMK while a pairing verification is initiated by the
paired peer. Since the PMK is not updated for responder's PASN context,
framework does not have a valid PMK and verification fails. Hence copy
the derived PMK to PASN context.

Currently, during association handling, if any of the iface parameters
changes due to some reason, it calls ieee802_11_set_beacons() function.
This function sets beacon for the all the BSSes in that iface even if
the beacon was not set already. This leads to setting the beacon
prematurely for some BSSes which was intentionally not started.
Fix the above issue by calling ieee802_11_update_beacons() function
instead. This function only updates the beacon if it was already set.
While at it, do the same while freeing STA entry.

Enumeration qca_wlan_roam_stats_frame_subtype defines the various frame
subtypes which may be collected by the driver and reported via the
QCA_WLAN_VENDOR_ATTR_ROAM_STATS_FRAME_SUBTYPE attribute.
Two of the enumerators are:
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_PREAUTH
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_REASSOC
These were initially defined and used to respectively report
Authentication Response and Reassociation Response frames.
Now there is a requirement to also report Authentication Request and
Reassociation Request frames. In order to satisfy this requirement,
add two new enumerators:
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_AUTH_REQ
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_REASSOC_REQ
Note that the first of these uses the standard term "AUTH" instead of
the confusing term "PREAUTH" used previously.
And to align with that naming, and in order to clearly show the usage
of the original enumerators, rename them to:
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_AUTH_RESP
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_REASSOC_RESP
Furthermore, Authentication Request/Response frame refers to the
Authentication frames sent by the non-AP STA and AP, respectively.
And finally, to support backward compatibility with applications using
the original enumerators, redefine those in terms of the new names.

Redesign the identity selection for MK derivation to be done explicitly
based on the last indicated identity (whether it is from
EAP-Response/Identity or method specific AT_IDENTITY) during the current
exchange. This makes the implementation cleaner and avoids cases were
more or less duplicated selection steps ended up being slightly
different. This is not as clean as it could otherwise be due to the
exception needed for the IMSI privacy case where the identity used in MK
derivation is actually not the one exchanged in the EAP messages.
Furthermore, this moves the somewhat confusing EAP method specific
tracking of the lasgt EAP-Response/Identity value from EAP-SIM/AKA into
the main EAP peer implementation.

Allow the EAP-SIM/AKA server to be configured to use a smaller limit for
the number of times fast re-authentication can be used before falling

While the EAP-SIM/AKA RFCs recommend against doing this, some deployed
authentication servers use the identity from the EAP-Response/Identity
directly without using an EAP method specific indication (AT_IDENTITY).
Having a capability to configure hostapd EAP server to behave in this
manner helps in increasing testing coverage for the EAP peer
implementation.

A case was missing in the way wpa_supplicant was tracking the identity
that is used when deriving MK if the EAP server does not follow the RFC
guidance on using EAP method specific identity determination (i.e.,
AT_IDENTITY for EAP-SIM/AKA) combined with a fallback from fast
re-authentication to full authentication. wpa_supplicant ended up using
the actual identity instead of the last identity included in an EAP
message even though MK derivation is supposed to use the identity that
was included in the last AT_IDENTITY or in the EAP-Response/Identity if
AT_IDENTITY was not used. This resulted in such an authentication
attempt failing due to incorrect MK being derived and AT_MAC validation
resulting in an mismatch.
Fix this by checking for the case where fast re-authentication is
attempted and the server recognizes the fast re-auth identity, but
decides to fall back to full authentication without a separate EAP
method specific identity exchange using AT_IDENTITY. This allows the
fast re-auth identity from EAP-Response/Identity to be used in MK
derivation in such cases.

cases where the MMPDU size limit prevents long buffers (e.g., all P2P
Action frames), it might be able to take tens of seconds on low-end CPUs
with maximum length EAP-WSC messages during WPS provisioning. More
visibly, this was causing OSS-Fuzz to time out a test case with

The previous PEAP client behavior allowed the server to skip Phase 2
authentication with the expectation that the server was authenticated
during Phase 1 through TLS server certificate validation. Various PEAP
specifications are not exactly clear on what the behavior on this front
is supposed to be and as such, this ended up being more flexible than
the TTLS/FAST/TEAP cases. However, this is not really ideal when
unfortunately common misconfiguration of PEAP is used in deployed
devices where the server trust root (ca_cert) is not configured or the
user has an easy option for allowing this validation step to be skipped.
Change the default PEAP client behavior to be to require Phase 2
authentication to be successfully completed for cases where TLS session
resumption is not used and the client certificate has not been
configured. Those two exceptions are the main cases where a deployed
authentication server might skip Phase 2 and as such, where a more
strict default behavior could result in undesired interoperability
issues. Requiring Phase 2 authentication will end up disabling TLS
session resumption automatically to avoid interoperability issues.
Allow Phase 2 authentication behavior to be configured with a new phase1
configuration parameter option:
'phase2_auth' option can be used to control Phase 2 (i.e., within TLS
tunnel) behavior for PEAP:
* 0 = do not require Phase 2 authentication
* 1 = require Phase 2 authentication when client certificate
(private_key/client_cert) is no used and TLS session resumption was
not used (default)
* 2 = require Phase 2 authentication in all cases

message. This is due to libnl immediately stopping processing the
current SKB upon receiving NL_STOP and not being able to process
NLMSG_DONE type message, and due to this wpa_supplicant's
finish_handler() not getting called. Fix this by returning NL_SKIP
instead while still ignoring all possible additional frequencies.

There are two hw modes (5 GHz and 6 GHz) with HOSTAPD_MODE_IEEE80211A
and the current hw mode may be wrong after one channel switch to 6 GHz.
This will cause hostapd_set_freq_params() to return -1 when saving
previous state and the second channel switch to fail. Fix this by adding
hostapd_determine_mode() before every channel switch.

Since there's only one instance of i802_bss for all BSSs in an AP MLD in
the nl80211 driver interface, the link ID is needed to forward the

Managements frames and report it in TX status.
