    Problem Summary PIN4U.00008 Conditions leading to an ENXIO error should be UNTESTED.
    Problem Text
    See Base resolution 1170/12. The test strategy is incorrect.

    The test determines the hard RLIMIT_FSIZE for a test file, sets the
    offset for the mmap call much greater than this and then makes an mmap
    call expecting an ENXIO error. RLIMIT_FSIZE should have no effect on the
    success or failure of mmap since RLIMIT_FSIZE controls the ability to
    extend a file, it does not control the ability to read or write into
    existing parts of the file. mmap never extends the file so RLIMIT_FSIZE
    is irrelevent.
    Test Output
    TEST PURPOSE #20
    If the implementation does not inhibit enforcement of
    limits for the resource RLIMIT_FSIZE:
    ENXIO in errno and return -1 on a call to void
    *mmap(void *addr, size_t len, int prot, int flags, int
    fildes, off_t off) when addresses in the range [off,
    (off+len)] are invalid for fildes.
    PREP: Obtain the system page size by call to
    sysconf(_SC_PAGESIZE)
    PREP: Establish signal handlers for SIGSEGV and SIGBUS
    PREP: Open a file and initialize it
    PREP: Allocate memory for buffer
    PREP: Now set proper permissions and re-open file
    PREP: Obtain the maximum size of a file
    TEST: Return -1 when the range [off,off+len] is
    invalid for the file descriptor
    ERROR: mmap() did not return -1
