NAK, set_bit() takes a bit number, not a mask. That is, assuming you can get away with a non-atomic operation on this field. I'll defer to Patrick on that.
I think you have to use IPS_CONFIRMED instead, e.g., ct->status |= IPS_CONFIRMED; rtg -- Tim Gardner tim.gardner@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
