  • File configure.ac — part of check-in [c615b62ed8] at 2024-04-16 23:50:40 on branch trunk — Don't use readdir_r

    readdir_r can easily lead to stack overflows if the path is longer than
    the space reserved for d_name in dirent. While some OSes use a length of
    MAXNAMLEN + 1, others use just 1. This could be worked around by always
    allocating a buffer of sizeof(struct dirent) + MAXNAMLEN (which would
    work only in case MAXNAMLEN is actually the longest readdir_r can
    return), but is probably not worth the risk, especially as glibc has
    entirely deprecated readdir_r and it is expected to be removed from
    POSIX. (user: js, size: 60786) [annotate] [blame] [check-ins using]
