    Test Suite VSRT version 5.0.1
    Test Identification rt.os/mfiles/mmap 26
    Problem Summary PG4R.00005 This test will fail if the address space limit is the max value of a size_t.
    Problem Text

    The test is trying to verify that:

    A call to mmap() for a shared memory object when
    MAP_FIXED is specified and the range [addr,addr+len]
    exceeds that allowed for the address space of a pro-
    cess shall return MAP_FAILED and set errno to ENOMEM.

    The test assumes that this limit is reflected in
    VSRT_ADDR_SPACE_PAGES, and fails if that parameter is not set:

    str = tet_getvar("VSRT_ADDR_SPACE_PAGES");
    if ((str == NULL) || (strlen(str) == 0)) {
    in_rpt("No VSRT_ADDR_SPACE_PAGES value specified
    in tet_exec.cfg
    ");
    xx_rpt(FAILURE);
    (void)close(fd);
    (void)shm_unlink(shbuf);
    DBUG_VOID_RETURN
    }

    In our implementation, there is no constraint but size_t on
    the size of a process address space, and no value of
    VSRT_ADDR_SPACE_PAGES will cause the expected error.

    The test suite should allow a value for VSRT_ADDR_SPACE_PAGES
    (perhaps -1) that returns UNSUPPORTED rather than FAIL in this
    case.

    Review Response
    We recommend this request be refused.

    Patch 5.0.1B provides a workaround for these failures. We
    recommend that the submitter be required to apply this patch
    prior to making a single branding run.

    The patch will be available during the week beginning 13 April.

    N.B. The correction allows the test to operate in the circumstances
    described (rather than implementing the change suggested by the submitter).
