Yes, it is clear that this is hitting r334824. V_ipfw_cntr_zone is defined with UMA_ZONE_PCPU. ipfw_alloc_rule() allocates from V_ipfw_cntr_zone with M_ZERO. That clearly violates the assertion added in r334824, as well as the assumption behind the commit: "Nothing in the tree uses it..." It seems like something will need to be changed here to resolve the mismatch in assumptions/expectations... :-/ If anyone is hitting this bug and needs to get a working system in the meantime, you'll need to revert the following commits which implemented (or updated) this change: r334830 r334829 r334824 JonathanReceived on Fri Jun 08 2018 - 13:40:46 UTC
