--- Comment #2 from commit-h...@freebsd.org --- A commit references this bug: Author: kp Date: Sun Jul 9 17:56:39 UTC 2017 New revision: 320848 URL: https://svnweb.freebsd.org/changeset/base/320848 Log: pf: Fix vnet purging pf_purge_thread() breaks up the work of iterating all states (in pf_purge_expired_states()) and tracks progress in the idx variable. If multiple vnets exist this results in pf_purge_thread() only calling pf_purge_expired_states() for part of the states (the first part of the first vnet, second part of the second vnet and so on). Combined with the mark-and-sweep approach to cleaning up old rules (in V_pf_unlinked_rules) that resulted in pf freeing rules that were still referenced by states. This in turn caused panics when pf_state_expires() encounters that state and attempts to access the rule. We need to track the progress per vnet, not globally, so idx is moved into a per-vnet V_pf_purge_idx.
