    Certification Program The Open Brand certification program
    Test Suite VSU version 5.0.2
    Test Identification VSU5/readv 22
    Problem Summary TSD4U.00259 This test may fail because tcsetattr() is not using a termios structure derived from a tcgetattr() call.
    Problem Text
    readv#22 on VSU5.0.2 contains the following change for readv#22.

    "vsusr554: tp22 - set termios information for slave loop device rather
    than master, since slave is the only interface defined to have
    termios properties when using pseudo terminals. "

    This change results in tcsetattr() failing EPERM on our platform,
    because tcgetattr() was not called for the termios structure used
    for the failing tcsetattr() call.

    The failing tcsetattr() call is made directly from the freadv22.c
    code, and uses struct termios ltermios. Immediately before this
    tcsetattr() call is made, termios_prep() is called and is passed
    the address for ltermios, but tcgetattr() was never called for
    ltermios as I'm sure was your intention.... spty_prep() is
    passed this address, but never passes it to spty_init() which DOES
    call tcgetattr(), tcsetattr() but only on a termios structure
    defined locally to spty_init()
    Test Output
    TEST CASE: readv

    TEST PURPOSE #22
    A call to ssize_t readv(int fildes, const struct iovec
    *iov, int iovcnt) when the function is interrupted by
    a signal after it has successfully read some data
    shall return the number of bytes read.
    PREP: Read IOV_MAX system configuration
    PREP: Allocate and initialize I/O buffers
    PREP: Open and initialize the terminal files
    ERROR: tcsetattr failed, errno = 139(EPERM - Not owner)
    PREP: Open and initialize the terminal files
    ERROR: tcsetattr failed, errno = 139(EPERM - Not owner)
    CLEANUP: Free iovec buffers
    22 UNRESOLVED
