The branch main has been updated by glebius: URL: https://cgit.FreeBSD.org/src/commit/?id=b508545ce044dbfdd83da772e73f969a3713d59d commit b508545ce044dbfdd83da772e73f969a3713d59d Author: Gleb Smirnoff <glebius@FreeBSD.org> AuthorDate: 2024-03-24 16:13:23 +0000 Commit: Gleb Smirnoff <glebius@FreeBSD.org> CommitDate: 2024-03-24 16:13:23 +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.
