https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D252551 Bug ID: 252551 Summary: POSIX compliance: writev does not return EINVAL when iovcnt =3D=3D 0 Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: asomers@FreeBSD.org POSIX requires that readv and writev return EINVAL when iovcnt =3D=3D 0. O= ur own man pages document that condition as well. https://pubs.opengroup.org/onlinepubs/9699919799/functions/writev.html https://pubs.opengroup.org/onlinepubs/9699919799/functions/readv.html However, we accept iovcnt =3D=3D 0, do nothing, and return 0. That's not inherently unreasonable, but it's not POSIX-compliant. From inspection, OpenBSD and NetBSD do not have this bug, but DragonflyBSD does. --=20 You are receiving this mail because: You are the assignee for the bug.=
