    Test Identification Base/sigaction 29
    Problem Summary PG4U.00002 When a SIGSTOP is raised the siginfo_t element si_status should be SIGCHLD.
    Problem Text
    The test suite currently assumes that when a SIGSTOP is raised against
    a process the siginfo_t element si_status will have the value of
    SIGSTOP. Under our implementation the value of this element is
    SIGCHLD. The si_status element is defined as follows

    int si_status exit value or signal.

    As there isn't any specification as to exactly what the signal value
    should be under this condition we maintain that this value should be a
    SIGCHLD since the signal that is generated is a SIGCHLD. At the
    minimum the test suite should accept either signal value or should not
    test this parameter at all since there isn't a definition available.
    Test Output
    TEST CASE: sigaction

    TEST PURPOSE #29
    After a call to int sigaction(int sig, const struct
    sigaction *act, struct sigaction *oact) with
    SA_SIGINFO set in the sa_flags member of the sigaction
    structure pointed to by act and sig equal to SIGCHLD,
    on entry to the signal catching function specified by
    the sa_handler member when the child has stopped the
    si_code member of the structure pointed to by the
    siginfo argument shall contain CLD_STOPPED, the si_pid
    member shall contain the child process ID, the
    si_status member shall contain the child's
    signal and the si_uid member shall contain the real
    user ID of the process that sent the signal.
    PREP: Set up action for SIGCHLD
    PREP: fork() a child that stops itself
    PREP: Generate SIGSTOP from child
    TEST: signal = SIGCHLD
    TEST: si_code = CLD_STOPPED
    TEST: si_status = SIGSTOP
    ERROR: si_status incorrect. Expected SIGSTOP, Received SIGCHLD
    CLEANUP: Set up SIG_IGN for SIGCHLD
    CLEANUP: Send SIGUSR1 to child
    29 FAIL

    Review Recommendation No Resolution Given
    Review Response
    Although it could be worded more clearly, the sigaction() spec
    states that the siginfo_t information will "explain the reason
    why the signal was generated". This indicates that the signal
    referred to in the si_status definition must be the SIGSTOP
    received by the child. This is the explanation for the SIGCHLD
    received by the parent.

    We recommend this request be refused.
