The branch main has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=9137c66c2ea6cc09e3a6f8a042ecdc5a62e0f39e commit 9137c66c2ea6cc09e3a6f8a042ecdc5a62e0f39e Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2026-05-03 11:02:15 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2026-05-03 11:02:15 +0000 tests/carp: Rework unicast_v4 For unicast tests, it is sufficient to use wait_for_carp() to verify the setup is sane. Additional sanity checks are not necessarily required but can serve purpose for redundancy. For some unclear reason routed(8) is advertising route to carp BACKUP. That makes the test flaky. Also routed(8) is marked deprecated and may be removed from base in the future. Let's just add static route entry manually for additional sanity checks. Other noticeable changes: 1. Add atf_check to configuration steps to prevent potential failure on setup. That helps diagnosing on failure. 2. Shorten the names of jails to improve readability. 3. Prefer `[ifconfig|route|sysctl] -j` over `jexec [ifconfig|route|sysctl]` to make the lines shorter.
