    Problem Report Number 1496
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0778
    Raised 1970-01-01 08:00
    Updated 2003-03-13 08:00
    Published 1995-08-12 08:00
    Product Standard Sockets (UNIX 95)
    Certification Program The Open Brand certification program
    Test Suite VSU version 4.0.2
    Test Identification Sockets/sendmsg 12
    Problem Summary TSD4U.00035 test may fail with EFAULT error
    Problem Text
    This test sets:
    Siovec[0].iov_len = 1L<<(bpss-2).
    This basically sets iov_len to a very big number.
    However the actual TestData is a very small array.
    Subsequently when the kernel checks to see if the address specified
    is legal, the kernel detects an illegal address range. Therefore
    the kernel generates a EFAULT.

    This test case should have created a valid buffer with a size equal
    to the stated iov_len.
    Test Output
    If the implementation supports a communications domain
    and a socket type:
    EINVAL in errno and return -1 on a call to ssize_t
    sendmsg(int socket, const struct msghdr *message, int
    flags) when the sum of the iov_len values overflows a
    ssize_t.
