From 9381e267b69acfea96c8429dc99da3e78835cef1 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 13 Sep 2016 16:11:32 +0200 Subject: [PATCH] cfg80211: wext: only allow WEP keys to be configured before connected When not connected, anything but WEP keys shouldn't be allowed to be configured for later - only static WEP keys make sense at this point. Change wext to reject anything else just like nl80211 does.
