Hi, i developed an app that uses libnetfilter_queue and i noticed that the behaviour of the nfq_unbind_pf function (from netfilter_queue) has changed: - up to kernel version 2.6.22.9 if you call it when there was no previous nfq_bind_pf the return value was not < 0 - with kernel 2.6.23 and same setup the return value is < 0 Was this change intentional? Because of that change your nfqnl_test app doesn't work anymore too, exiting with the message "NFNETLINK answers: Invalid argument" (as Jorch reported in another email). The fix i'm thinking to use is described here (see my comment at 2007-Oct-11 23:50): http://developer.berlios.de/bugs/?func=detailbug&bug_id=12156&group_id=2509 is that the right way for an app to bind/unbind?
