024b4b2a29 AP: Unsolicited broadcast Probe Response configuration
Add hostapd configuration options for unsolicited broadcast
Probe Response transmission for in-band discovery in 6 GHz.
Maximum allowed packet interval is 20 TUs (IEEE P802.11ax/D8.0
26.17.2.3.2, AP behavior for fast passive scanning).
Setting value to 0 disables the transmission.

4a7e0ac268 hostapd: Add an option to notify management frames on ctrl_iface
In some contexts (e.g., Multi-AP) it can be useful to have access to
some of the management frames in upper layers (e.g., to be able to
process the content of association requests externally).

Add 'notify_mgmt_frames'. When enabled, it will notify the ctrl_iface
when a management frame arrives using the AP-MGMT-FRAME-RECEIVED event
message.

Note that to avoid completely flooding the ctrl_iface, not all
management frames are included (e.g., Beacon and Probe Request frames
are excluded).

1a7963e36f AP: Allow PTK rekeying without Ext KeyID to be disabled as a workaround
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.

466e48dcd7 HT: Remove SMPS in AP mode
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")
8f461b50cf ("HT: Pass the smps_mode in AP parameters")
da1080d721 ("nl80211: Advertise and configure SMPS modes")

0cb39f4fd5 HE: Extend BSS color support
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.

65a44e849a OWE: PTK derivation workaround in AP mode
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.
