This message was printed and MSG_INFO level which would be more
reasonable for error cases where hostapd has accepted authentication.
However, this is not really an error case for the cases where
authentication was rejected (e.g., due to MAC ACL). Drop this to use

When Probe Request frame handling was extended to use MAC ACL through
ieee802_11_allowed_address(), the MSG_INFO level log print ("Station
<addr> not allowed to authenticate") from that function ended up getting
printed even for Probe Request frames. That was not by design and it can
result in excessive logging and MSG_INFO level if MAC ACL is used.
Fix this by printing this log entry only for authentication and
association frames. In addition, drop the priority of that log entry to
MSG_DEBUG since this is not really an unexpected behavior in most MAC
ACL use cases.

This makes it more convenient to generate the URL in a way that

In the infrastructure BSS case, the AP needs to clear pending SAE state
if a new Commit message is received when already in Committed state.
This allows the non-AP STA to negotiate a new group if it ends up trying
to go through SAE authentication again before the AP side has removed
the previous STA entry.
This fixes an issue where a kernel update changed something in SAE
timing or authentication sequence and started failing the
sae_bignum_failure hwsim test case.

When removing an interface, hostapd_bss_deinit() frees all associated
STAs. If any of the stations is 40MHz intolerant, the cleanup invokes
ht40_intolerant_remove(), that in turn registers a 20->40MHz transition
timer for the last station (ap_ht2040_timeout() function). That timer is
never canceled; once it executes, the interface is gone, most likely
resulting in a segfault when referencing it.
While hostapd_interface_deinit() cancels the transition timer, it does
so before cleaning up STAs. Move the cancellation after STA cleanup to
cancel any timer that was registered during that operation.

The AKM 00-0F-AC:13 is supposed to use cryptographic algorithms
consistently, but the current IEEE 802.11 standard is not doing so for
the key names: PMKID (uses SHA-1), PMKR0Name/PMKR1Name (uses SHA-256).
The PMKID case was already implemented with SHA-384 and this commit
replaces use of SHA-256 with SHA-384 for PMKR0Name/PMKR1Name derivation
to be consistent in SHA-384. While this is not compliant with the
current IEEE 802.11 standard, this is clearly needed to meet CNSA Suite
requirements. Matching change is being proposed in REVmd to get the IEEE

A new SAE Commit message should not be allowed to drop an existing STA
entry since the sender of that Commit message cannot be authenticated
before receiving the Confirm message. This is important in particular
when PMF is used since this would provide a potential new path for
forcing a connection to be dropped.
Fix this by allowing a new SAE Authentication instance to be started
when the old instance is in Accepted state and the new Commit message
does not use the same peer-scalar value (checked in
sae_parse_commit_scalar()). When PMF is used, the AP will use SA Query
procedure when receiving the (Re)Association Request frame. In theory,
that step could be skipped in case of SAE Authentication since the
non-AP STA is demonstrating knowledge of the password. Anyway, there is
no allowance for that exception in the IEEE 802.11 standard, so at least
for now, leave this using SA Query procedure just like any other PMF
case.

2. hostapd_cli -p /var/run/hostapd chan_switch 10 5200 center_freq1=5200 \
bandwidth=20 ht
====> Comes up in VHT20
This is since VHT config from chan_switch is processed only for
bandwidths 80 and above (80P80, 160) and for VHT20, VHT40 cases, only
NLA chan type and chan width are updated.
There is no NL attribute for determining if it is HT or VHT for
bandwidths 20 & 40 and currently they are updated as HT20, HT40 (+ or -
depending on offset). Same is notified back via
NL80211_CMD_CH_SWITCH_NOTIFY.
Instead of adding new NL attribute for tracking HT/VHT enabled config,
we are adding new hostapd VHT config parameter to save the chan_switch
config and use only for chan_switch case of VHT20 and VHT40.

When the channel time is zero the interference factor calculation falls
under divide by zero operation which results in invalid (NaN =
not-a-number) interference factor value. This leads to wrong ideal
channel selection in ACS during the scenario described below.
Scenario:
In VHT80 mode, the channel 36 (first channel) gets the channel time as
zero which causes the interfactor factor to be an invalid number (NaN).
Any operations (like addition, mulitplication, divide, etc.) with NaN
value results in a NaN value, so that average factor for the primary
channel 36 got the invalid value (NaN). Since channel 36 is the first
channel, ideal factor is assigned as NaN in the first iteration. The
following iteration condition check (factor < ideal_factor) with a NaN
value fail for all other primary channels. This results in channel 36
being chosen as the ideal channel in ACS which holds a NaN value.
Logs:
ACS: Survey analysis for channel 36 (5180 MHz)
