    Problem Summary TSD4U.00317 The test may fail on systems with a large IOV_MAX.
    Problem Text
    Thereis a bug in test39 from XOPEN. The sysconf(_SC_IOV_MAX) are used
    in many readv, writev, recvmsg and sendmsg tests. (Acually sensmsg
    test12 is a corresponding test of recvmsg test39.) All these tests
    contain such lines after getting return value of iovnum = sysconf(_SC_IOV_MAX)
    if(iovnum > IOVNUM)
    iovnum = IOVNUM;
    where
    #define IOVNUM 16
    is defined in each test source codes.

    Only recvmsg test39 did not do that. It must be a mistake in the test
    code.

    The tests that do a sysconf(_SC_IOV_MAX) and forcefully bring down the
    iovnum to 16 are:
    ioprim/readv:
    1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22,
    23, 48, 49, 51, 52, 53, 54, & 57.
    iopriv/writev:
    1, 2, 4, 5, 6, 8, 9, 10, 12, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24,
    25, 26, 27, 28, 29, 30, 31, 32, 50, 51, 52, 53, 54, 55, 56, 58, 61, 67,
    68, 70, 71, 72
    sockets/recvmsg:
    39 (should do the same!)
    sockets/sendmsg:
    12

    This seems to be the same as TSD4U.00210, granted for VSU5 5.0.2.
    We are therefore requesting that either that TSD be extended to
    cover the current case, or that a new TSD be granted for this case.
    Test Output
    VSU test case CAPI.os/sockets/recvmsg/T.recvmsg failed with the
    following message:
    /tset/CAPI.os/sockets/recvmsg/T.recvmsg 39 Failed

    Test Description:
    Base Conditional Deviance
    If the implementation supports a communications domain and a socket
    type:
    EINVAL in errno and return -1 on a call to ssize_t recvmsg(int socket,
    struct msghdr *message, int flags) when the sum of the iov_len values
    overflows an ssize_t.

    Test Information:

    PREP: Determine if the function sbrk() is supported
    INFO: The implementation supports the Legacy Feature Group
    PREP: Read IOV_MAX system configuration
    PREP: Test whether condition can be generated
    PREP: Set up invalid iovec
    TEST: AF_INET SOCK_STREAM
    PREP: Create test sockaddr_in: address = 130.62.32.200, port = 3029
    PREP: Server: create socket
    PREP: Server: bind address 130.62.32.200, port 3029 to socket
    PREP: Server: listen on socket
    PREP: Server: notify client server is ready
    PREP: Server: accept connection
    INFO: Server: accepted connection from address 130.62.32.200, port 8524
    PREP: echo_server: read and echo data
    INFO: echo_server: echoed 25 bytes of data (ABCDEFGHIJKLMNOPQ123TEST!)
    INFO: Server received signal 15
    INFO: Server terminated
    PREP: Wait for server to be ready
    PREP: Create a socket
    PREP: Connect socket to address 130.62.32.200, port 3029
    PREP: Send test data
    TEST: Return -1 when iov_len values overflows an ssize_t
    TEST: EINVAL in errno when iov_len values overflows an ssize_t
    ERROR: recvmsg failed unexpectedly expected errno = EINVAL, errno = 97(EMSGSIZE -
    Message too large)
    CLEANUP: Send SIGTERM to server
