The branch stable/14 has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=78e30818a06c0cb934637811c3339ea8da9ed16a commit 78e30818a06c0cb934637811c3339ea8da9ed16a Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2023-11-26 04:27:11 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2023-12-15 00:58:33 +0000 lockf: switch to strtonum() for parsing timeout Convert waitsec to a long long to be able to hold the full domain of alarm(3) timeout on all platforms, and let strtonum(3) handle the input validation. strtonum(3) also happens to provide a neater interface for error handling, and it already includes our pre-existing empty input check.
