Ieee80211r configuration with OpenWrt LUCI setup

Installing and Using OpenWrt Network and Wireless Configuration

ieee80211r configuration with openwrt LUCI setup.
i wanted to setup ieee80211r functionality with openwrt[version of (chaos calmer,r48067)]
using LUCI or uci commands.

validated the hostapd binaries with 11r configuration files manualy(using hostapd cmnds)it was working fine!

Tried setting up 11R configuration in /etc/config/wireless as below

config wifi-device  wifi0
        option type     qcawifi
        option channel  auto
        option macaddr  8c:fd:f0:0a:f3:81
        option hwmode   11a
        # REMOVE THIS LINE TO ENABLE WIFI:
        option disabled 0
 
config wifi-iface
        option device   wifi0
        option network  lan
        option mode     ap
        option ssid     11R_AP
        option encryption psk2+ccmp
        option key 123456
        option ieee80211r '1'
        option nasid '14DD20BE88C8'
        option mobility_domain '4f58'
        option r0_key_lifetime '10000'
        option r1_key_holder '14DD20BE88C8'
 
        option reassociation_deadline '1000'
        option pmk_r1_push '1'
        list r0kh '14:DD:20:47:14:E4,14DD204714E4,00112233445566778899aabbccddeeff'
        list r0kh '14:DD:20:47:14:E5,14DD204714E5,00112233445566778899aabbccddeeff'
        list r1kh '14:DD:20:47:14:E4,14:DD:20:47:14:E4,00112233445566778899aabbccddeeff'
        list r1kh '14:DD:20:47:14:E5,14:DD:20:47:14:E5,00112233445566778899aabbccddeeff'
 
$wifi down
$wifi up

Observed that hostapd.conf is created with 11r params in /var/run/hostapd-ath0.conf

But Interface is not coming up in required mode(11r),it is beaconing open mode.

  1. I would like to know does LUCI supports GUI configuration for 11R ?
  2. I suspect issue in parsing hostapd config file,how to debug that?
  3. installed wpad package and observed the 11r patches applied .
    https://dev.openwrt.org/changeset/45051/
    https://github.com/openwrt/luci/commit/f02794f28c343070487bbc794b425f91b675fdb9

Any clue to achieve 11R support with openwrt LUCI will be appreciated
Thanks in advance.

If you're willing to patch a file and install it (meaning copy a new hostapd.sh into place) on your boxes,
https://github.com/lede-project/source/pull/1382
is the way I manage it myself. It is regrettably closed because it wasn't accepted in some time period. Can't completely vouch for its technical correctness, but "works for me" and I see "[WPA-PSK-FT/PSK-CCMP][ESS]" from my channel scanner as well as iOS devices doing the FT authenticate.

is another good link and somewhere I came across https://pastebin.com/RxKg3php as what looks like an 802.11r config.

Running wpad-mesh here.

Parsing /etc/config/wireless is generally done by shell scripts in /lib/netifd

hostapd has to be recompiled to get debug-level output, otherwise the macro gets compiled out, CONFIG_WPA_MSG_MIN_PRIORITY=2 gets debug, without going totally crazy.

Hi @jeff, this is a really helpful thread it's taken me days to find!

I'm in exactly the same position as OP - my config results in the AP broadcasting in open mode. What would the best place to get a new hostapd.sh? And would I have to compile it myself?

I got it working (on the face of it) yet to test it:
