[Prism54-devel] Open System Authentication

[Stephan Lück]

Hi,

when configuring open encryption with 'iwconfig eth1 key ... open' 
the WLAN-Adapter Netgear WG511 does not associate with 
the access point. If open system authentication is enabled then 
everything work fine.

Therefore, I suggest to integrate the following patch:

-	if ((dwrq->flags & IW_ENCODE_OPEN) || force)
+	if ((dwrq->flags & IW_ENCODE_OPEN) || force) {
 		/* Encode but accept non-encoded packets. No auth */
 		invoke = 1;
+		authen = DOT11_AUTH_OS;
+	}
 	if ((dwrq->flags & IW_ENCODE_RESTRICTED) || force) {
 		/* Refuse non-encoded packets. Auth */
 		authen = DOT11_AUTH_BOTH;


In addition, it might be useful if the user was able to control
authentication *separately*  from encryption. What do you think about
adding a private ioctl call which allows to use open system authentication
in combination with restricted encryption?

If you have any comments, please CC them to me. I'm not subscribed to this list.

Thanks
