https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260894 Bug ID: 260894 Summary: Nonexportable file systems are usable over NFSv4 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 If I arrange for VFS_MOUNT to return EINVAL when MNT_EXPORT is set, add its entry to /etc/fstab, and run "service mountd onereload", then the following happens: * mountd logs "can't export /mnt" to /var/log/messages. * `showmount -e` does not list the file system. * If I try to mount it from a client with NFS3, it always returns ESTALE. However, I can still mount it from a client with NFS v4.2, and successfully browse it. This seems like a bug. I would expect that mounting such a file system with NFS v4.2 would work similarly to mounting a non-exported file system: the mount would appear to succeed, but then `ls` would only show an empty directory. -- You are receiving this mail because: You are the assignee for the bug.
