Hi <span style="color: rgb(0, 0, 0);">Pavel Roskin</span>.<br>I debugged again and found the error comes from set80211priv(struct madwifi_driver_data *drv, int op, void *data, int len) in driver_madwifi.c file.<br><br>When it run to ioctl(drv->ioctl_sock, op, &iwr) , it return a value of -1, and then set80211priv() return -1 with the message ioctl[IEEE80211_IOCTL_SETMLME]: Argument list too long in the end.<br>
<br>I print the value of drv->ioctl_sock and op and it's drv->ioctl_sock=3,op=35824 in my platform.<br><br>Can you give me some ideas to resolve this solution? Thank you very much.<br><br><br>Regards£¬<br>Peter Zhou<br>

</div>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>
