    Problem Report Number 1326
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0608
    Raised 1970-01-01 08:00
    Updated 2003-03-13 08:00
    Published 1998-02-27 08:00
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSU version 5.0.2
    Test Identification CAPIbase/fmmap 24,42
    Problem Summary TSD4U.00209 These tests may fail due to a type mismatch.
    Problem Text

    These tests fail because of type mismatches for the pgsz and ipgsz
    variables. In SRC/LIB/capi_mmap/mkmmap.c, the following is defined:

    unsigned long int pgsz;
    unsigned long int ipgsz;


    but in dmmap24.c and dmmap42.c the following is found:

    extern int pgsz;
    extern int ipgsz;


    This results in pgsz being set to zero, accounting for
    the errors above.
    Test Output
    TEST CASE: mmap

    TEST PURPOSE #24
    If the implementation provides a file type for which
    mmap is not supported:
    ENODEV in errno and return MAP_FAILED on a call to void
    *mmap(void *addr, size_t len, int prot, int flags, int
    fildes, off_t off) when fildes refers to an object for
    which mmap() is not supported.
    PREP: Obtain the system page size by call to
    sysconf(_SC_PAGESIZE)
    PREP: Establish signal handlers
    PREP: Obtain the configuration variable VSU_FILE_NO_MMAP
    PREP: Open file /dev/slog
    TEST: Return MAP_FAILED when file descriptor refers to a
    device which is not supported
    ERROR: mmap() did not return MAP_FAILED
    Expected :ffffffffffffffff Received: 0
    24 FAIL


    TEST PURPOSE #42
    The mapping established by a call to void *mmap(void
    *addr, size_t len, int prot, int flags, int fildes,
    off_t off) shall replace any previous mappings for
    those whole pages containing any part of the address
    space of the process starting at pa and continuing for
    len bytes.
    PREP: Obtain the system page size by call to
    sysconf(_SC_PAGESIZE)
    PREP: Establish signal handlers
    PREP: Create the file ../tmp/mmap42.file.1
    PREP: Allocate memory for buffer
    ERROR: malloc failed, errno = 22(EINVAL - Invalid argument)
    42 UNRESOLVED
