I try to use the authsae in 802.11s network.
I am using openwrt with the latest mac802.11 (2013-02-22).
I am using the Thomas Pedersen patch to add the authsae package in my
openwrt source tree
(http://permalink.gmane.org/gmane.linux.drivers.mesh.open80211s/2530)
To enable the 802.11s and HT20 (or HT40) I need to change the
/lib/wifi/mac80211.sh. Before call mac80211_authsae_setup_mbss I need to
call :
iw dev $ifname set freq $freq $htmode
ifconfig $ifname up
Without these calls, the HT mode is not enabled on my mesh network (I
check with wireshark, I don't have the HT tag in beacon). I looking for
understand why the authsae do not enable the HTmode.
My authsae config file is
authsae:
{
sae:
{
debug = 480;
password = "acksystest";
group = [19, 26, 21, 25, 20];
blacklist = 5;
thresh = 5;
lifetime = 3600;
};
meshd:
{
meshid = "cvtest";
interface = "wlan0";
passive = 0;
debug = 1;
mediaopt = 1;
band = "11a";
channel = 36;
htmode = "HT20";
};
};
When I run "wifi up" I have a kernel panic. The crash dump is

The authsae work correctly if the HT mode is not enabled (in 802.11a
only for exemple).
Best regards.
