    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)

    Certification Program The Open Brand certification program
    Test Suite VSU version 4.1.1
    Test Identification sockets/sendmsg 12
    Problem Summary TSD4U.00188 This test may fail due to memory management logic errors.
    Problem Text
    A waiver is requested for this variation of the test suite
    deficiency TSD4U.00170, which applies to test purpose 12 of the
    "sendmsg" test case in the "sockets" section of VSU.

    The above excerpt, labeled "JOURNAL EXCERPT FROM BRANDING RUN",
    shows the results of the test suite's corruption of memory, initiated
    during "AF_INET SOCK_STREAM" phase and completed in the
    "AF_UNIX SOCK_STREAM" phase. As documented in TSD4U.00170, the test
    suite effectively obtains a memory address from sbrk(0) then passes it
    to free(). Per the XSH, this behavior is undefined, and, as such,
    it corrupts the state of implementation's malloc() and free() logic.
    The failure which appears in the journal as

    |ERROR: unix_server: bind to file ../tmp/unix.a002YD failed, errno =
    9(EBADF - Bad file number)

    is due to a file descriptor value which was assigned correctly in an
    internal structure prior to a calloc() call then found to be corrupted
    afterward.

    The excerpt entitled "JOURNAL EXCERPT FROM INDIVIDUAL TEST PURPOSE"
    shows that when run by itself, this test case fails in the same manner
    as that documented in TSD4U.00170.

    We believe this to be a test suite deficiency and request a waiver.
