Ignore unauthenticated encrypted EAPOL-Key data in supplicant
processing. When using WPA2, these are frames that have the Encrypted
flag set, but not the MIC flag.
When using WPA2, EAPOL-Key frames that had the Encrypted flag set but
not the MIC flag, had their data field decrypted without first verifying
the MIC. In case the data field was encrypted using RC4 (i.e., when
negotiating TKIP as the pairwise cipher), this meant that
unauthenticated but decrypted data would then be processed. An adversary
could abuse this as a decryption oracle to recover sensitive information
in the data field of EAPOL-Key messages (e.g., the group key).

When we start hostapd having Hotspot 2.0 configuration with interface
already added to bridge interface, addition and deletion of new neighbor
to bridge ip neighbor table fails.
This is since 'bss->added_if_into_bridge' is not set which only allows
'drv->rtnl_sk' (nl_sock for NETLINK_ROUTE) allocation needed for bridge
ip neighbor table.
Add a new bit 'already_in_bridge' and set it when interface is already
added to bridge by some external component. Check this bit in addition
to 'bss->added_if_into_bridge' for 'drv->rtnl_sk' allocation done in
i802_init().
Now 'drv->rtnl_sk' is closed in wpa_driver_nl80211_deinit() regardless of
'bss->added_if_into_bridge' since when we have 'bss->already_in_bridge'
case too, this need to be removed.

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.

Prefer channels that support VHT80 (and secondarily, HT40 on the same

prefer any channel that uses the same band so that CSA can be used. This
improves the case where a P2P GO needs to move to another channel and
there is no other reason (e.g., preferred channel from the driver or an
already used channel from a virtual interface sharing the same radio) to
pick a specific channel.

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
802.11 standard to meet the use case requirements.

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.
