f972420e82 AP MLD: Fix AID allocation for legacy STA
Currently, AID is not allocated properly in hostapd for legacy non-MLD
STA in case of an AP MLD. All such stations have same AID.

Fix this issue by allocating AID properly in hostapd when operating as
an AP MLD and the STA is not an MLD.

14c5f401f0 Remove forgotted STAKey related functionality in EAPOL-Key Request
The use of a MAC KDE in the Key Data field of an EAPOL-Key Request frame
was only for the STAKey handshake. That handshake was implemented in
2005 as an experimental functionality and it was then removed in 2006.
However, this part of the functionality was forgotten. This does not do
anything in practice, so simplify the implementation and remove it.

392114a179 FT: Add dynamic reload of RxKH definitions from file
hostapd reads the list of Rx Key Holders from hostapd.conf file.
However, for systems where topology changes dynamically, the update
of RxKHs list is required without reloading the whole configuration.

Introduce a new source of RxKH definition with original syntax:
- rxkh_file - Path to a file containing a list of RxKHs.

In addition, add a control interface command RELOAD_RXKHS to
reload RxKHs definition from the file specified in `rxkh_file`.

This allows hostapd to properly distribute Rx keys even after topology
change (assuming rxkh_file is updated and reload_rxkhs command issued).

Syntax of rxkh_file is the same as extraction of r0kh and r1kh options
from original hostapd.conf file.

```
r0kh=ff:ff:ff:ff:ff:ff * 00112233445566778899aabbccddeeff

f7a903654f Extend mechanism to distinguish EAPOL-Key msg 2/4 from 4/4
The initial Authenticator implementation depended on the Key Data field
being empty for EAPOL-Key msg 4/4. This worked fine for years in
practice, but in theory, vendor specific elements or KDEs could have
been added inti EAPOL-Key msg 4/4 and that would have broken this
design. In addition, the MLD case did introduce a KDE into EAPOL-Key msg
4/4 and required changes here.

As an initial step to make this more robust for future extensions,
recognize a received EAPOL-Key message as msg 4/4 if it is for RSN
(i.e., not WPAv1), has Secure=1, contains an unencrypted Key Data field,
and does not include RSNE.

af6e21faa0 P2P: Fix a logical error of workaround of extended listen failure
When p2p->state == P2P_LISTEN_ONLY, the statement before it
'p2p->cfg->is_p2p_in_progress(p2p->cfg->cb_ctx)' will be true, too, so
this function will print a message "Operation in progress" and return;
the workaround to handle listen failure will be never reached.

I met such an error when the 'remain-on-channel' command failed, then
the function p2p_ext_listen_timeout() just printed 'Operation in
progress' again and again, and the listen operation was not started
anymore.

98f3bd26de ACS: Extend the 320 MHz support
There are bandwidth 320 MHz-1 and 320 MHz-2 channelization in EHT mode.
When using ACS, user might prefer one of the channelization or both, but
original ACS was unable to take such preference.

Another problem is that the original ACS returns only the ideal channel
but no 320 MHz channelization. The function acs_get_bw_center_chan()
also could not correctly return the center frequency of bandwidth 320
MHz that is decided by ACS.

For example, if ACS decide the ideal channel is channel 37 with
channelization 320 MHz-2 (center frequency 6265 MHz),
acs_get_bw_center_chan() returns 6105 MHz, which is 320 MHz-1.

Extend the support for 320 MHz so that ACS can choose the best channel
according to the user's preference. Also, after calling
acs_find_ideal_chan_mode(), the best channel and bandwidth can be
derived.

The changes are:
- bw_type ACS_BW320 is divided into ACS_BW320_1 and ACS_BW320_2
- in bandwidth 320 MHz, find the best channel and bandwidth according to
  user's perference (320 MHz-1, 320 Mhz-2 or both are OK)
- before acs_find_ideal_chan_mode() returns, update bw320_offset in
  iface->conf so that the best channel's channelization is recorded.
- get the best center frequency from bw320_offset

c8dd70cfb1 Fix Multiple BSSID element length calculation
Currently while deciding to create a new Multiple BSSID element based on
the condition when the length reaches 255, the length value being used
is the total element length (including the length of the Element ID and
Length fields as well). However, the value in the length field denotes
the number of octets following it and excluding itself. Hence including
the total length is wrong. This leads to incorrect count of Multiple
BSSID elements.

And while filling the data, the length is considered porperly as it
should be hence we are filling more data in a single go and all data is
filled in MBSSID count which is less than originally calculated. This
ultimately leads to incorrect length calculation during nla_put() and
setting the beacon to the driver fails while putting the Multiple BSSID
element data into the netlink socket buffer.

Fix this issue by considering the length excluding the Element ID and
Length field sizes.

2ab56694f6 Split ap_sta_set_authorized() into two steps
This function is both updating the hostapd-internal sta->flags value and
sending out the AP-STA-CONNECTED control interface message. When
authorizing a STA, the call to this function is followed by a driver
command to update the flags of the STA entry in the driver. That has a
race condition at least for UML time-travel since the AP-STA-CONNECTED
event is used as a message to wait for before running a connectivity
test or some other operation that depends on the data connection being
in working condition.

Split the function into two steps so that the driver STA entry update
can be done between those two steps for the cases where it matters for
the race condition. In other words, send the AP-STA-CONNECTED message
only after having authorized the STA in the driver.

Non-DFS one saves previous BW value in iface->conf, but DFS flow
replaces it with a new user requested value. Setting a non-DFS channel
after a DFS one with BW = 160 would have resulted in a mismatch between
the saved BW and vht_capab (if VHT160 was not included by default). This

8e294c3a2c P2P: Recover from successfully requested, but not started, listen
It is possible for the start_listen() callback to be called to request
the driver to start a driver operation and stop_listen() called
immediately after that (e.g., due to a request to transmit a P2P Public
Action frame) before the driver has had time to start ROC and send an
event to notify of that. Such a sequence could result in
p2p->pending_listen_freq being left to a nonzero value without getting a
call to p2p_listen_cb() to clear it. This would stop an ongoing P2P
listen operation since no following p2p_listen() call would start the
listen due to the pending command being assumed to be in effect.

Fix this by detecting this particular sequence and clearing
p2p->pending_listen_freq.

This was found with the p2p_listen_and_offchannel_tx test case with the
new kernel scheduled and UML time-travel.

With changes to optimize scan for specific BSSID, there arises a
scenario where in nl80211_trigger_scan() is called with a scan
randomization enabled. A combination of NL80211_ATTR_MAC for BSSID and
scan randomization, which uses NL80211_ATTR_MAC for a different purpose,
results in invalid error for the scan request. To fix the issue use
attribute NL80211_ATTR_BSSID instead of NL80211_ATTR_MAC.

NL80211_ATTR_BSSID was introduced in kernel commit 2fa436b3a2a7
("nl80211: Use different attrs for BSSID and random MAC addr in scan
req") in 2016. Prior to that, only NL80211_ATTR_MAC could be used for
specifying the target BSSID. For backwards compatibility, add the
NL80211_ATTR_MAC attribute as well when not using a random MAC address.
