Hi: While working on rhashtable I noticed that wireless is walking rhashtables by hand using rht_for_each_*. You must not do that as an rhashtable can entail multiple hash tables when resizing. If you walk it by hand then you may end up missing entries. The correct way to do it is to use the rhashtable walk interface. However, even this comes with the caveat that a given entry may show up multiple times. So if you cannot handle that then you must construct your own data structure outside of rhashtable, like we do in IPsec. So the question is can wireless handle seeing an entry multiple times? In particular, __ieee80211_rx_handle_packet would appear to process the same packet multiple times if this were to happen.
