Some legacy stations copy previously reserved RSN capability bits,
including OCVC, in (Re)Association Request frames from the AP's RSNE but
do not indicate MFP capability and/or do not send OCI in RSN handshakes.
This is causing connection failures with such erroneous STAs.
To improve interoperability with such legacy STAs allow a workaround OCV
mode to be enabled to ignore OCVC=1 from the STA if it does not follow
OCV requirements in the first protected exchange. This covers cases
where a STA claims to have OCV capability, but it does not negotiate use
of management frame protection or does not include OCI in EAPOL Key msg
2/4, FT Reassociation Request frame, or FILS (Re)Association Reqest.
The previous behavior with ocv=1 is maintained, i.e., misbehaving STAs
are not allowed to connect. When the new workaround mode is enabled with
ocv=2, the AP considers STA as OCV capable on below criteria
- STA indicates both OCV and MFP capability
- STA sends OCI during connection attempt in a protected frame
Enabling this workaround mode reduced OCV protection to some extend
since it allows misbehavior to go through. As such, this should be
enabled only if interoperability with misbehaving STAs is needed.

Support Extended Key ID in hostapd according to IEEE Std 802.11-2016.
Extended Key ID allows to rekey pairwise keys without the otherwise
unavoidable MPDU losses on a busy link. The standard is fully backward

ID support in the same BSS.

Rekeying a pairwise key using only keyid 0 (PTK0 rekey) has many broken
implementations and should be avoided when using or interacting with
one. The effects can be triggered by either end of the connection and
range from hardly noticeable disconnects over long connection freezes up
to leaking clear text MPDUs.
To allow affected users to mitigate the issues, add a new hostapd
configuration option "wpa_deny_ptk0_rekey" to replace all PTK0 rekeys
with disconnection. This requires the station to reassociate to get
connected again and as such, can result in connectivity issues as well.

SM Power Save was described in somewhat unclear manner in IEEE Std
802.11n-2009 as far the use of it locally in an AP to save power. That
was clarified in IEEE Std 802.11-2016 to allow only a non-AP STA to use
SMPS while the AP is required to support an associated STA doing so. The
AP itself cannot use SMPS locally and the HT Capability advertisement
for this is not appropriate.
Remove the parts of SMPS support that involve the AP using it locally.
In practice, this reverts the following commits:
04ee647d58 ("HT: Let the driver advertise its supported SMPS modes for AP mode")

The HE Operation field for BSS color consists of a disabled, a partial,
and 6 color bits. The original commit adding support for BSS color
considered this to be a u8. This commit changes this to the actual
bits/values.
This adds an explicit config parameter for the partial bit. The disabled
is set to 0 implicitly if a bss_color is defined.
Interoperability testing showed that stations will require a BSS color
to be set even if the feature is disabled. Hence the default color is 1
when none is defined inside the config file.

Initial OWE implementation used SHA256 when deriving the PTK for all OWE
groups. This was supposed to change to SHA384 for group 20 and SHA512
for group 21. The new owe_ptk_workaround parameter can be used to enable
workaround for interoperability with stations that use SHA256 with
groups 20 and 21. By default, only the appropriate hash function is
accepted. When workaround is enabled (owe_ptk_workaround=1), the
appropriate hash function is tried first and if that fails, SHA256-based
PTK derivation is attempted. This workaround can result in reduced
security for groups 20 and 21, but is required for interoperability with
older implementations. There is no impact to group 19 behavior.

This adds support for a new EAP method: EAP-TEAP (Tunnel Extensible
Authentication Protocol). This should be considered experimental since
RFC 7170 has number of conflicting statements and missing details to
allow unambiguous interpretation. As such, there may be interoperability
issues with other implementations and this version should not be
deployed for production purposes until those unclear areas are resolved.
This does not yet support use of NewSessionTicket message to deliver a
new PAC (either in the server or peer implementation). In other words,
only the in-tunnel distribution of PAC-Opaque is supported for now. Use
of the NewSessionTicket mechanism would require TLS library support to
allow arbitrary data to be specified as the contents of the message.

This adds support to hostapd for configuring airtime policy settings for
stations as they connect to the access point. This is the userspace
component of the airtime policy enforcement system PoliFi described in
this paper: https://arxiv.org/abs/1902.03439
The Linux kernel part has been merged into mac80211 for the 5.1 dev
cycle.
The configuration mechanism has three modes: Static, dynamic and limit.
In static mode, weights can be set in the configuration file for
individual MAC addresses, which will be applied when the configured
stations connect.
In dynamic mode, weights are instead set per BSS, which will be scaled
by the number of active stations on that BSS, achieving the desired
aggregate weighing between the configured BSSes. Limit mode works like
dynamic mode, except that any BSS *not* marked as 'limited' is allowed
to exceed its configured share if a per-station fairness share would
assign more airtime to that BSS. See the paper for details on these
modes.

enabling groups that are not as strong as the mandatory-to-support group
19 (i.e., groups 25 and 26). In addition, this disables heavier groups
by default.
In addition, add a warning about MODP groups 1, 2, 5, 22, 23, and 24

The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the WPS Registrar offers a
different set of credentials (backhaul credentials instead of fronthaul
credentials) when the Multi-AP subelement is present in the WFA vendor
extension element of the WSC M1 message.
Add new configuration options to specify the backhaul credentials for
the hostapd internal registrar: multi_ap_backhaul_ssid,
multi_ap_backhaul_wpa_psk, multi_ap_backhaul_wpa_passphrase. These are
only relevant for a fronthaul SSID, i.e., where multi_ap is set to 2 or
3. When these options are set, pass the backhaul credentials instead of
the normal credentials when the Multi-AP subelement is present.
Ignore the Multi-AP subelement if the backhaul config options are not
set. Note that for an SSID which is fronthaul and backhaul at the same
time (i.e., multi_ap == 3), this results in the correct credentials
being sent anyway.
The security to be used for the backaul BSS is fixed to WPA2PSK. The
Multi-AP Specification only allows Open and WPA2PSK networks to be
configured. Although not stated explicitly, the backhaul link is
intended to be always encrypted, hence WPA2PSK.
To build the credentials, the credential-building code is essentially
copied and simplified. Indeed, the backhaul credentials are always
WPA2PSK and never use per-device PSK. All the options set for the
fronthaul BSS WPS are simply ignored.
