    Test Identification base/poll 25
    Problem Summary TSD4U.00138 This test may fail on implementations because CL_BIND is not being passed to unix_client().
    Problem Text
    We are seeing the same behaviour on our implementation for
    poll#25 and select#2 as referenced in TSD4U.00062, however
    the journal for poll#25 is slightly different. For the
    AF_UNIX SOCK_DGRAM test:
    We see
    ERROR: poll returned 0 (call timed out)
    The journal in TSD4U.00062 contains
    ERROR: poll failed, errno = 4 (EINTR - Interrupted system call)

    However the cause is the same, the CL_BIND flag was not set
    when unix_client() is called.

    Our journal for select#2 is the same as contained in TSD4U.00062,
    I have included it here for completeness.

    Please note, the journal for poll#25 contains 2 unrelated errors
    for tty ERROR: open failed, errno = 139(EPERM - Not owner)
    and for STREAMS
    and the select#2 journal contains the same STREAMS failure.
    These are unrelated to and do not affect the behaviour covered
    in this IR.
    Test Output
    TEST CASE: poll

    TEST PURPOSE #25
    If the implementation supports a communications domain
    and a socket type:
    A call to int poll(struct pollfd fds[], nfds_t nfds,
    int timeout) shall support regular files, terminals
    and pseudo-terminal devices, STREAMS-based files,
    sockets, FIFOS and pipes.

    Review Response
    We agree this is a test suite deficiency in the test
    suite version(s) listed.

    Although this request would normally be refused as a duplicate of
    TSD4U.00062 the test logic changed between 4.0.2 and 4.1.0. The
    output in TSD4U.00062 is what would be expected when running
    4.0.2. The output here is expected when running 4.1.0. Since
    4.0.2 is no longer a valid indicator of compliance we suggest
    this be request approved and TSD4U.00062 no longer be allowed
    as a waiver for 4.1.0.

    Please note that our agreement for poll #25 is with regard
    to the error

    ERROR: poll returned 0 (call timed out)

    not the error

    ERROR: open failed, errno = 139(EPERM - Not owner)

    An additional waiver is required for this error.
