The branch stable/12 has been updated by kp: URL: https://cgit.FreeBSD.org/src/commit/?id=bca83d9e7f5b7faa925ca7edde6129f57adcd09d commit bca83d9e7f5b7faa925ca7edde6129f57adcd09d Author: Kristof Provost <kp@FreeBSD.org> AuthorDate: 2021-07-28 09:24:44 +0000 Commit: Kristof Provost <kp@FreeBSD.org> CommitDate: 2021-07-31 09:14:44 +0000 pf: fix ABI breakage The introduction of synproxy support changed the size of struct pf_status, which in turn broke the userspace ABI. Revert the relevant change. More work is needed on the synproxy code to keep and expose the counters, but in the mean time this restores the ABI.
