0059fa5bae 6 GHz: Fix secondary channel setting
center_idx_to_bw_6ghz() does not return the bandwidth in MHz and as
such, the check here against 20 (MHz) is never true. The returned value
is greater than 0 for the over 20 MHz cases.

4e86692ff1 AP: Fix 6 GHz AP setup after disable-enable
Once ACS picks a channel, iface->freq and iface->conf->channel are
updated. So, AP comes up in the last operating channel when 'ENABLED'
after 'DISABLED' though ACS is configured.

But this will fail for 6 GHz APs since configured_fixed_chan_to_freq()
checks if iface->conf->channel is filled or not irrespective of ACS
configuration, and the checks inside configured_fixed_chan_to_freq()
fail the AP setup. Fix this by clearing iface->freq and
iface->conf->channel in AP setup for ACS configuration.

ba150059d1 FT: Store PMK-R0/PMK-R1 after EAPOL-Key msg 2/4 MIC validation
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.

72b8193f41 MACsec: Remove EAP Session-Id length constraint

least 65 octets long and by truncating the value to that length, the
practical limit of functional cases was limited to that exact length of

does not work with most other EAP methods.

Remove the EAP Session-Id length constraint and allow any length of the
Session-Id as long as the EAP method provides one. In addition, simplify
this be removing the unnecessary copying of the Session Id into a new
allocated buffer.

d9d5e55c54 DPP: Respond to GAS on the same channel it was received on
When I was testing dpp_auth_init on an AP with Enrollee on a different
channel from the AP I was getting failures. This happened on hwsim in
UML with time-travel for me. I don't recall seeing this with real
devices, presumably because of lax offchan implementation.

The DPP authentication would succeed. However the station would then try
to get configuration through a GAS request and fail.

The AP reported the following logs (grepped):

> 1614762426.860212: RX_ACTION category 4 action 10 sa 02:00:00:00:01:00 da 02:00:00:00:00:00 len 227 freq 2412

> 1614762428.861186: DPP: Timeout while waiting for Configuration Result
> 1614762428.861186: wlan0: DPP-CONF-FAILED

While the STA reported the following logs (grepped):

> 1614762426.860193: wlan1: DPP-AUTH-SUCCESS init=0
> 1614762426.860195: DPP: Stop listen on 2412 MHz

> 1614762428.861189: DPP: GAS query did not succeed

AP would still receive the GAS request on ch1 but would then try to
respond on ch11 while STA was waiting on ch1.

c46351d10e DFS: Clear cac_started when AP is disabled
When AP is started on a DFS channel and DFS is offloaded to the driver,
AP setup will be separated to two stages. In the first stage, hostapd
will set frequency and initialize BSS, then waits the driver CAC to
complete. Once CAC done, in the second stage,
hostapd_setup_interface_complete() will be called again from a callback
to continue AP/channel setup.

But the driver will fail to restart AP if it is disabled/reenabled
during a driver CAC procedure because some steps such as setting
freq/beacon in the first stage are skipped due to cac_started not
cleared when the AP is disabled.

Avoid this by clearing cac_started when the AP is disabled.

c5a09b051a mbssid: Add Non-Inheritance element
Add data per IEEE Std 802.11-2020, 9.4.2.240. Current implementation is
added for the security and extended supported rates only.

For the Extended rates element, add a new member 'xrates_supported'
which is set to 1 only if hostapd_eid_ext_supp_rates() returns success.
Without this change, there are cases where this function returns before
adding the element for the transmitting interface resulting in incorrect
addition of this element inside the MBSSID Non-Inheritance element.

920b56322d mbssid: Functions for building Multiple BSSID elements
Add Multiple BSSID element data per IEEE Std 802.11ax-2021, 9.4.2.45.
Split the BSSes into multiple elements if the data does not fit in
the 255 bytes allowed for a single element.

Store the total count of elements created and the offset to the start
of each element in the provided buffer.

Set the DTIM periods of non-transmitted profiles equal to the EMA
profile periodicity if those are not a multiple of the latter already as
recommended in IEEE Std 802.11ax-2021, Annex AA (Multiple BSSID
configuration examples).

931e5d4f9e mbssid: Configure all BSSes before beacon setup
When multiple BSSID advertisement feature is enabled in IEEE 802.11ax
mode or later, Beacon frames are not transmitted per interface, instead
only one of the interfaces transmits Beacon frames that include one or
more Multiple BSSID elements with configuration for the remaining
interfaces on the same radio.

Change the existing logic such that all configuration details for all
the interfaces are available while building the Beacon frame template
for the transmitting interface itself.

Do not change the flow for the cases where multiple BSSID advertisement
is not enabled.

7452e54477 mbssid: Add new configuration option
Add configuration option 'mbssid' used to enable multiple BSSID (MBSSID)
and enhanced multiple BSSID advertisements (EMA) features.

Reject the configuration if any of the BSSes have hidden SSID enabled.
