This looks a bit strange taken into account this same handle_assoc_cb()
function is using the WLAN_STA_WDS flag just below this:
if (sta->flags & WLAN_STA_WDS) {
int ret;
char ifname_wds[IFNAMSIZ + 1];
ret = hostapd_set_wds_sta(hapd, ifname_wds, sta->addr,
sta->aid, 1);
if (!ret)
hostapd_set_wds_encryption(hapd, sta, ifname_wds);
}
All that would become dead code if this patch were applied. Is this code
really supposed to be removed? If so, these lines should be deleted as
well. If not, this issue would likely need to be fixed in some other
manner.
