The branch stable/13 has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=1a7136cf2942ba895e3e7ce9d524afca1b1c8e08 commit 1a7136cf2942ba895e3e7ce9d524afca1b1c8e08 Author: Math Ieu <sigsys@gmail.com> AuthorDate: 2022-10-27 17:01:57 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2022-11-11 18:08:57 +0000 split: reset errno prior to getline() Something else may have set errno, breaking the post-getline() logic that tries to detect the getline() error. This was initially noted in a jail on a system that has HPET, in a jail that does not expose /dev/hpet0 -- we see an earlier error in libc's vdso bits.
