The branch stable/13 has been updated by tuexen: URL: https://cgit.FreeBSD.org/src/commit/?id=a71eee300ba7d94a1621c7b31eaaa79243db84ec commit a71eee300ba7d94a1621c7b31eaaa79243db84ec Author: Gleb Smirnoff <glebius@FreeBSD.org> AuthorDate: 2024-03-24 16:13:23 +0000 Commit: Michael Tuexen <tuexen@FreeBSD.org> CommitDate: 2025-02-12 10:22:14 +0000 icmp: when logging ICMP ratelimiting message use correct jitter value The limiting of the very last second has been done using certain jitter value. We update the jitter for the next second. But the logging should report the jitter before the change.
