David Howells: > http://git.infradead.org/users/dhowells/unionmount-testsuite.git I've found some interesting cases. - impermissible.test, open_file_as_bin -t -w $file -E EACCES When $termslash is "/", a '/' is appended to the expanded $file, such as "/path/fileA/". If fileA is a regular file, that path is obviously wrong. Does UnionMount expect EACCES in this case too? Should it be ENOTDIR? It might be better to change errcode=EACCES test ! "$termslash" = "" && errcode=ENOTDIR open_file_as_bin -t -w $file -E $errcode - readlink.test, fs_op readlink $file -R $testdir/direct_dir_sym100 ${termslash:+-E EINVAL} It expects "$testdir/direct_dir_sym100". Does it mean UnionMount converts the target path? For example, - /u = /rw + /ro - /rw/symlinkA doesn't exist - /ro/symlinkA points to /ro/fileA Does readlink(2) return "/u/fileA" instead of "/u/fileA"? And all tests should be done by a superuser? J.
