    Problem Text
    This testcase fails because of problems with the cleanup test for each of
    the three tests: message queue, shared memory, and semphore. The cleanup
    calls ExecWithPriv ALLPRIV ipcrm with appropiate flags to rm the ipc information.
    Then ipcs is used to check that it is removed. However, the test is using
    ExecWithPriv ALLPRIV to execute the ipcs -q command. This is not necessary
    and is returning a erronous exit status causing the test to report failure.

    Code for the message queue cleanup looks like this:

    JrnlMsg CLEANUP: remove message queue
    ExecWithPriv ALLPRIV ipcrm -Q $msg_key
    if [ $? -ne 0 ]; then
    SetResult $TET_FAIL "Command failed: 'ipcrm -Q $msg_key'"
    else
    SetResult $TET_PASS
    fi

    JrnlMsg CLEANUP: message queue is gone
    ExecWithPriv ALLPRIV ! ipcs -q | grep $msg_key >/dev/null
    if [ $? -ne 0 ]; then
    SetResult $TET_FAIL "Command failed: '! ipcs -q | grep $msg_key >/dev/null'"
    else
    SetResult $TET_PASS
    fi

    Review Response
    We recommend this request be refused.

    While the test issue is in the cleanup step of the test, we believe
    the syntax and usage is correct and is not a deficiency. The command

    ! ipcs -s | grep 0xa000000 >/dev/null

    is a valid command and should not report an error. The ExecWithPriv
    command is necessary, since some IUTs may classify ipcs as a privileged
    command.

    The ! character is a reserved word (Commands and Utilities,
    Section 2.9.2 Pipelines) and is valid shell syntax:

    If the reserved word "!" does not precede the pipeline, the
    exit status will be the exit status of the last command
    specified in the pipeline. Otherwise, the exit status will be
    the logical NOT of the exit status of the last command. That
    is, if the last commnd returns zero, the exit status will be
    1; if the last command returns greater than zero, the exit
    status will be zero.

    As a result, this is probably an issue with the IUT shell or IUT
    configuration.
