</div></div></div><div><div></div><div class="h5">It looks like the IEEE80211_IOCTL_GETWPAIE request is failing with<br>
-EINVAL. MadWifi would process it in ieee80211_ioctl_getwpaie(), which<br>
would fail if the request size mismatches what MadWifi expects.<br>
<br>
Maybe sizeof(struct ieee80211req_wpaie) is different in userspace and in<br>
the kernel for your platform?<br>
<br>
Perhaps the easiest solution would be to apply this patch to MadWifi and<br>
recompile both MadWifi and hostapd. Please report if it made any<br>
difference for you.<br>
<br>
If it doesn't help, please print iwr->u.data.length and sizeof(wpaie) in<br>
the beginning of ieee80211_ioctl_getwpaie() in MadWifi.<br>
