Use ft_psk_generate_local=1 by default, as it makes everything else fairly
trivial. All of the r0kh/r1kh and key management stuff goes away and hostapd
fairly much does it all for us.
We do need to provide nas_identifier, which can be derived from the BSSID,
and we need to generate a mobility_domain, for which we default to the first
four chars of the md5sum of the SSID.
The complex manual setup should also still work, but the defaults also
now work easily out of the box. Verified by manually running hostapd
(with the autogenerated config) and watching the debug output:
wlan2: STA ac:37:43:a0:a6:ae WPA: FT authentication already completed - do not start 4-way handshake

The max_oper_chwidth settings was parsed incorrectly for big endian system.
This prevented the system to switch to VHT80 (or VHT160). Instead they were
mapped to:
* HT20: 20MHz
* VHT20: 20MHz
* HT40: 40MHz
* VHT40: 40MHz
* VHT80: 40MHz
* VHT160: 40MHz
This happened because each max_oper_chwidth setting in the config file was
parsed as "0" instead of the actual value.

that the existing hostapd option tdls_prohibit can be used to further

hostapd advertise that use of TDLS is not allowed in the BSS.
Note: If an attacker manages to lure both TDLS peers into a fake

possible to bypass this protection.

iw to join and IBSS/mesh. But it was not done when wpa_supplicant was used
to join an encrypted IBSS or mesh.
This configuration is required when an AP interface is configured together
with an mesh interface. The beacon_int= line must therefore be re-added to
the wpa_supplicant config. The value is retrieved from the the global

The wpa_supplicant code for IBSS allows to set the mcast rate. It is
recommended to increase this value from 1 or 6 Mbit/s to something higher
when using a mesh protocol on top which uses the multicast packet loss as
indicator for the link quality.
This setting was unfortunately not applied for mesh mode. But it would be
beneficial when wpa_supplicant would behave similar to IBSS mode and set
this argument during mesh join like authsae already does. At least it is
helpful for companies/projects which are currently switching to 802.11s
(without mesh_fwding and with mesh_ttl set to 1) as replacement for IBSS
because newer drivers seem to support 802.11s but not IBSS anymore.

One of the latest mac80211 updates added sanity checks, requiring the
beacon intervals of all VIFs of the same radio to match. This often broke
AP+11s setups, as these modes use different default intervals, at least in
some configurations (observed on ath9k).
Instead of relying on driver or hostapd defaults, change the scripts to
always explicitly set the beacon interval, defaulting to 100. This also
applies the beacon interval to 11s interfaces, which had been forgotten
before. VIF-specific beacon_int setting is removed from hostapd.sh.

When sta is configured, hostapd receives 'stop' and 'update' command from
wpa_supplicant. In the update command, hostapd gets sta parameters with
which it configures ap.
Problem is, with the default wireless configuration:
mode:11g freq:2.4GHz channel:1
If sta is connected to 5GHz network, then ap does not work. Ideally with
340-reload_freq_change.patch hostapd should reload the frequency changes
and start ap in 5GHz, but ap becomes invisible in the network.
This issue can be reproduced with following /etc/config/wireless:
config wifi-device radio0
option type mac80211
option channel 1
option hwmode 11g
option path 'virtual/uccp420/uccwlan'
option htmode 'none'
config wifi-iface 'ap'
option device 'radio0'
option encryption 'none'
option mode 'ap'
option network 'ap'
option ssid 'MyTestNet'
option encryption none
config wifi-iface 'sta'
option device radio0
option network sta
option mode sta
option ssid TestNet-5G
option encryption psk2
option key 12345
