4cb23b66d6 ACS: Allow selecting a better channel when using 40/80/160 MHz
When considering a channel for a bandwidth of 40/80/160 MHZ on the 5 GHz
or 6 GHz band, allow selecting one of the other channels in the segment
instead of the first one. This is done only if the other channel's
interference_factor is lower than the first one's.

472101684b ACS: introduce acs_adjust_secondary
When using 40/80/160 MHz bandwidth on the 5 GHz or 6 GHz band, enforce
the secondary channel to be the other channel of the corresponding 40
MHz segment.

Even if this is useless for now, this is preparatory work to allow ACS
to select a primary channel which is not the first of its segment.

ed8e13decc ACS: Extract bw40/80/160 freqs out of acs_usable_bwXXX_chan()
This extracts the 3 lists of allowed channels for 40/80/160 MHz
bandwidth out of their respective functions. It also adds for each
segment the frequency of the segment's last channel and the index of the
segment's "center" channel.

This is preparative work to allow selecting a channel which is not the
first of its segment for 40/80/160 MHz. In addition, this adds the 5 GHz
160 MHz channel defined for 5735-5895 MHz (channels 149-177).

af1528a128 hostapd: Add RELOAD_BSS
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.

b37c3fbad4 hostapd: Add config_id parameter
Add a new configuration parameter: config_id.

If set, only do hostapd_clear_old() for the BSSes for which the
config_id changed.

This makes it possible to reconfigure specific BSSes on a radio,
without disconnecting clients connected to other, unchanged BSSes of
the same radio.

This patch adapted from a patch authored by John Crispin in the
OpenWrt repository:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=package/network/services/hostapd/patches/700-wifi-reload.patch;h=c5ba631a0fc02f70714cb081b42fcf6cb9694450;hb=60fb4c92b6b0d1582d31e02167b90b424185f3a2

46f6a32775 Split BSS-specific hostapd_clear_old_bss() from hostapd_clear_old()
In hostapd_clear_old() multiple steps are needed to clear a BSS.
There are some places where it would be desirable to clear only some
BSSes and not all.

To make it easier to clear only some BSSes, split hostapd_clear_old()
with hostapd_clear_old_bss(), which does the same actions but on a
single BSS.

c823197bde SAE: Use Challenge Failure status code in confirm message failure cases
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
ieee802_11.c the function sae_check_confirm() is called and in case of
verification failure (-1 is returned), the response is set to
WLAN_STATUS_UNSPECIFIED_FAILURE (status code = 1). Fix this to use
CHALLENGE_FAILURE.

b6c38cee93 Skip CAC if the driver switches channel to non-DFS
If an AP is started on a DFS channel (or any channels within its
bandwidth require DFS) and DFS is offloaded to the driver, hostapd needs
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
start the AP because hostapd fails to receive a CAC complete event and
cannot finish interface setup.

Skip CAC and complete AP setup in the channel switch event handler for
this case.

40a42613e6 FT: Simplify FTE parsing for FT-SAE-EXT-KEY using MIC Length subfield
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().

bc36991791 Use Secure=1 in PTK rekeying EAPOL-Key msg 1/4 and 2/4
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
the case of rekeying. Change implementation to match that. This bit was
already practically ignored on the reception side, so this should not
have impact on actual functionality beyond this one bit changing its
value in the frame.

8690374439 Discard unencrypted EAPOL/EAP when TK is set and PMF is enabled (AP)
RSN design is supposed to encrypt all Data frames, including EAPOL
frames, once the TK has been configured. However, there are deployed
implementations that do not really follow this design and there are
various examples from the older uses of EAPOL frame where those frames
were not encrypted. As such, strict filtering of unencrypted EAPOL
frames might results in undesired interoperation issues.

However, some of the most important cases of missing EAPOL frame
encryption should be possible to handle without causing too significant
issues. These are for cases where an attacker could potentially cause an
existing association to be dropped when PMF is used. EAPOL-Start and
EAPOL-Logoff are potential candidate for such attacks since those frames
could be used to terminate an authentication or initiate a new EAP
authentication. Such an attack could result in the station ending up
disconnecting or at minimum, getting into somewhat mismatching state
with the AP.

Drop EAPOL-Start/Logoff/EAP frames on the AP/Authenticator when it is
known that it was not encrypted but should have been and when PMF is
enabled. While it would be correct to drop this even without PMF, that
does not provide any significant benefit since it is trivial to force
disconnection in no-PMF cases. It should also be noted that not all
drivers provide information about the encryption status of the EAPOL
frames and this change has no impact with drivers that do not indicate
whether the frame was encrypted.
