2c6147404e Check Key Descriptor Version value earlier in the process
There is no need to try to process the EAPOL-Key frame if it has an
unexpected Key Descriptor Version value. Move these checks to happen
earlier in the sequence. In adition, use a separate helper function for
this to simplify wpa_receive() a bit.

9e9afd9569 Extend frequency configuration to handle 6 GHz channel 2
In hostapd_set_freq_params(), if center_segment0 is 2, call
ieee80211_chan_to_freq() with operating class 136 instead of 131.

This is needed because, channel 2 is an exception in the 6 GHz band. It
comes before channel 1 and is part of operating class 136.

Channels order in 6 GHz:
    2 (Operating Class 136)
    1   5   9 ....  (Operating Class 131)

4037c0ac1e nl80211: Fix wiphy event handling when the driver is deinitialized
Radar detection event could have resulted in the driver interface
instance getting deinitialized and the related memory freed in the
middle of the loop. This was not an issue when the event was passed only
into a single interface, but it became an issue when the loop tried to
send it to all interfaces. If the driver were removed, that loop check
would have used freed memory. Avoid this by explicitly checking that the
driver interface instance is still valid.

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.
