    Subject[ 16/34] ecryptfs: read on a directory should return EISDIR if not supported
    2.6.32-longterm review patch.  If anyone has any objections, please let me know.


    From: Andy Whitcroft <>

    commit 323ef68faf1bbd9b1e66aea268fd09d358d7e8ab upstream.

    read() calls against a file descriptor connected to a directory are
    incorrectly returning EINVAL rather than EISDIR:

    [XSI] [Option Start] The fildes argument refers to a directory and the
    implementation does not allow the directory to be read using read()
    or pread(). The readdir() function should be used instead. [Option End]

    This occurs because we do not have a .read operation defined for
    ecryptfs directories. Connect this up to generic_read_dir().
