I want to monitor pf tagged mbufs, but (without kld hacks) I can see only IN or OUT direction, because PFIL insert hooks in reverse order. Hack like this works, but is ugly: # kldload mymodule # mymodule -enable PFIL_OUT # kldload pf # pfctl -e # mymodule -enable PFIL_IN How about PFIL_HEAD, PFIL_TAIL flags for pfil_add_hook? pfil_list_add() ... if (flags & PFIL_IN) { if (flags & PFIL_TAIL) TAILQ_INSERT_TAIL(list, pfh1, pfil_link); else TAILQ_INSERT_HEAD(list, pfh1, pfil_link); } else { if (flags & PFIL_HEAD) TAILQ_INSERT_HEAD(list, pfh1, pfil_link); else TAILQ_INSERT_TAIL(list, pfh1, pfil_link); }
