mac80211: fix invalid band deref building preq IEs The function building probe-request IEs does not validate the band is supported before dereferencing it. This can result in a panic when all bands are traversed, as done during sched-scan start. Warn when this happens and return an empty probe request. Also fix sched-scan to not waste memory on unsupported bands. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
