The branch stable/14 has been updated by kp: URL: https://cgit.FreeBSD.org/src/commit/?id=228ae54114e1efbe82686090bed9d2c8071ecea0 commit 228ae54114e1efbe82686090bed9d2c8071ecea0 Author: Kristof Provost <kp@FreeBSD.org> AuthorDate: 2023-10-27 12:13:57 +0000 Commit: Kristof Provost <kp@FreeBSD.org> CommitDate: 2023-11-07 15:46:52 +0000 libpfctl: be more tolerant of kernel extensions Allow the kernel to supply more array elements than expected, but cut off when we hit what we think the maximum is. This will improve forward compatibility (i.e. old userspace with newer kernel).
