Revision 4d6c13f87db12ae1ce35ea6a15688ac72419b133 authored by Bryan Donlan on 30 June 2009, 18:41:24 UTC, committed by Linus Torvalds on 01 July 2009, 01:56:00 UTC
ext2_iget() returns -ESTALE if invoked on a deleted inode, in order to report errors to NFS properly. However, in ext[234]_lookup(), this -ESTALE can be propagated to userspace if the filesystem is corrupted such that a directory entry references a deleted inode. This leads to a misleading error message - "Stale NFS file handle" - and confusion on the part of the admin. The bug can be easily reproduced by creating a new filesystem, making a link to an unused inode using debugfs, then mounting and attempting to ls -l said link. This patch thus changes ext2_lookup to return -EIO if it receives -ESTALE from ext2_iget(), as ext2 does for other filesystem metadata corruption; and also invokes the appropriate ext*_error functions when this case is detected.
