There is a delay between sending Association Response frame after having
received Association Request frame, due to the fact that between
receiving the request and sending the response the Beacon frame contents
is updated, after analyzing inputs from the STA. There may be several
updates if multiple fields need to change. This can cause issues with
some devices in noisy environments with many BSSs and connected STAs.
Optimize this by updating the beacon only once, even if there are
multiple reasons for updates.

When it comes to set some BSS's beacon, there are two reasons to
update the beacon of co-located hostapd_iface(s) at the same time:
1. 6 GHz out-of-band discovery
2. MLD operational parameters update
BSS load update is unrelated with the above two reasons, and therefore
is not the case to update beacon for co-location. Moreover, updating
beacon for co-location when BSS load update makes hostapd set beacon too
frequently, which makes hostapd busy setting beacon in a multi-BSS case.
Add a new function to update beacon only for current BSS and use the
function during BSS load update.

Some station devices are apparently sending the EAPOL-Logoff message in
some cases before the initial authentication for WPA2/WPA3-Enterprise.
hostapd would have forced a "post EAP-Failure" disconnection in 10 ms
for such cases while still allowing the EAP authentication to try to
complete.
This is not ideal and could result in interoperability issues, so skip
the forced disconnection in the particular case where the EAPOL-Logoff
message is received before the first authentication is completed.
In addition, disconnect the STA without starting new EAP authentication
and the 10 ms delay if an EAPOL-Logoff message is received after
authentication has been completed successfully. This results in cleaner
behavior by avoiding the extra start of a new EAP authentication in a
case where the STA is going to be disconnected shortly.

When AP is brought up in HE40/EHT40 with ACS, the AP comes up with 20
MHz bandwidth. It is expected to come up with 40 MHz bandwidth.
conf->secondary_channel does not hold the correct value and it leads to
choosing 20 MHz in hostapd_set_freq_params(). conf->secondary_channel is
filled using the hostapd config he_oper_centr_freq_seg0_idx. When AP is
configured to use ACS, the hostapd config he_oper_centr_freq_seg0_idx is
not valid as the channel is not known during bring up. So using the
config he_oper_centr_freq_seg0_idx to fill the conf->secondary_channel
does not work with ACS.
Use op_class to determine the bandwidth and based on the bandwidth fill
the conf->secondary_channel to address this ACS case.

As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of
a nontransmitted BSSID profile, an EMA AP that transmits a Beacon
frame carrying a partial list of nontransmitted BSSID profiles
should include in the frame a Reduced Neighbor Report element
carrying information for at least the nontransmitted BSSIDs that
are not present in the Multiple BSSID element carried in that frame.
Add this support by splitting the reduced neighbor report (RNR) in as
many elements as the number of multiple BSSID elements. Each RNR element
excludes the non-transmitting profiles already included in the MBSSID
element at the same index. If present, the last additional group will

gathered through neighbor reports.

hostapd was previously storing the derived PMK-R0 and PMK-R1 as soon as
these keys were derived. While that is fine for most purposes, it is
unnecessary to do that so quickly and if anything were to fail before
the supplicant is able to return a valid EAPOL-Key msg 2/4, there would
not really be any real use for the derived keys.
For the special case of FT-PSK and VLAN determination based on the
wpa_psk file, the VLAN information is set in the per-STA data structures
only after the EAPOL-Key msg 2/4 MIC has been verified. This ended up
storing the PMK-R0/PMK-R1 entries without correct VLAN assignment and as
such, any use of the FT protocol would not be able to transfer the VLAN
information through RRB.
Split local storing of the FT key hierarchy for the cases using the FT
4-way handshake so that PMK-R0 and PMK-R1 are first derived and then
stored as a separate step after having verified the MIC in the EAPOL-Key
msg 2/4 (i.e., after having confirmed the per-STA passphrase/PSK was
selected) and VLAN update. This fixes VLAN information for the
wpa_psk_file cases with FT-PSK.

But the driver will fail to restart AP if it is disabled/reenabled

When using multiple BSSes on a single radio, it is sometimes desirable
to reconfigure one BSS, without disconnecting the stations already
connected to other BSSes on the same radio.
When a BSS is reconfigured using the SET command, there is no "old"
configuration we can compare to (so we cannot compare a hash of the
configuration for example).
One possible solution would be to make the current RELOAD command
reload only the current BSS. However, that could break the workflow of
existing users. Instead, introduce a new RELOAD_BSS command, which
reloads only the current BSS.

IEEE Std 802.11-2020, 12.4.7.6 says that status code CHALLENGE_FAILURE,
needs to be sent in case the verification action fails for SAE Confirm
message frame from a STA: "An SAE Confirm message, with a status code
not equal to SUCCESS, shall indicate that a peer rejects a previously
sent SAE Confirm message. An SAE Confirm message that was not
successfully verified is indicated with a status code of
CHALLENGE_FAILURE."
hostapd, however, did not use this status code for this case. In

verification failure (-1 is returned), the response is set to
WLAN_STATUS_UNSPECIFIED_FAILURE (status code = 1). Fix this to use

If an AP is started on a DFS channel (or any channels within its

to wait for CAC to complete. But the driver may not do CAC and just
switches to a non-DFS channel instead. This would result in a failure to

cannot finish interface setup.

Commit 25b52e5f83 ("FT: Extend FTE parsing for FT-SAE-EXT-KEY") used
possible MIC length iteration to try to figure out the length of the MIC
field in FTE. That was the only option available at the time, but FTE is
now being extended in IEEE 802.11-REVme to explicitly indicate the
length of the MIC field for the new FT-SAE-EXT-KEY AKM to make this
easier.
Use the new design from the approved comment resolution (*) in
REVme/D2.0 ballot CID 3135 to simplify implementation. This gets rid of
the need to pass in key length and the somewhat strange need_{r0kh,r1kh}
parameters to wpa_ft_parse_ies().

IEEE Std 802.11-2020 is ambiguous on how the Secure bit is set in
EAPOL-Key msg 1/4 and 2/4 in the case where 4-way handshake is use to
rekey the PTK. 12.7.2 describes this with "set to 1 once the initial key
exchange is complete" while 12.7.6 shows EAPOL-Key msg 1/4 and 2/4 using
Secure=0 without any consideration on whether the handshake is for
rekeying.
TGme seems to be moving towards clarifying this to use Secure=1 based on
there being a shared PTKSA between the Authenticator and the Supplicant.
In other words, this would use Secure=1 in EAPOL-Key msg 1/4 and 2/4 in

already practically ignored on the reception side, so this should not
have impact on actual functionality beyond this one bit changing its
