    glusterd: Buffer overflow causing crash for glusterd

    Problem: In GLUSTERD_GET_DEFRAG_PROCESS we are using PATH_MAX (4096)
    as the max size of the input for target path, but we have allocated
    NAME_MAX (255) size of buffer for the target.

    Now this crash is not seen with source install, but is seen with RPMS.
    The reason is _foritfy_fail. This check happens when _FORTIFY_SOURCE
    flag is enabled. This option tries to figure out possible
    overflow scenarios like the bug here and does crash the process.
