Florian Weimer <fweimer@redhat.com>:

    dd_opendir() should keep a file handle (opened with O_DIRECTORY) and
    use openat() and similar functions to access files in it.

    ...

    The file system manipulation functions should guard against hard
    links (check that link count is <= 1, just as in the user coredump
    code in abrt-hook-ccpp), possibly after opening the file
    with O_PATH first to avoid side effects on open/close.
