Modified files: sys/net : pf_ioctl.c sbin/pfctl : parse.y Log message: rdomain IDs do not need to exist for "on rdomain N" to work Unlike "... rtable N", pf.conf(5)'s "on rdomain N" does not alter packet state and will always work no matter if rdomain N currently exists or not, i.e. the rule "pass on rdomain 42" will simply match (and pass) packets if rdomain 42 exists, and it will simply not match (neither pass nor block) packets if 42 does not exist. There's no need to reload the ruleset whenever routing domains are created or deleted, which can already be observed now by creating an rdomain, loading rules referencing it and deleting the same rdomain immediately afterwards: pf will continue to work as expected. Relax both pfctl(8)'s parser check as well as pf(4)'s copyin routine to accept any valid routing domain ID without expecting it to exist at the time of ruleset creation - this lifts the requirement to create rdomains before referencing them in pf.conf while keeping pf behaviour unchanged. Prompted by yasuoka's recent pfctl parse.y r1.702 commit requiring an rtable to exist upon ruleset creation. Discussed with claudio and bluhm at k2k20. Feedback sashan OK sashan yasouka claudio
