Author: kp Date: Sun Mar 19 03:06:09 2017 New Revision: 315529 URL: https://svnweb.freebsd.org/changeset/base/315529 Log: pf: Fix rule evaluation after inet6 route-to In pf_route6() we re-run the ruleset with PF_FWD if the packet goes out of a different interface. pf_test6() needs to know that the packet was forwarded (in case it needs to refragment so it knows whether to call ip6_output() or ip6_forward()). This lead pf_test6() to try to evaluate rules against the PF_FWD direction, which isn't supported, so it needs to treat PF_FWD as PF_OUT. Once fwdir is set correctly the correct output/forward function will be called.
