    [TCP]: Invoke tcp_sendmsg() directly, do not use inet_sendmsg(). · 3516ffb0
    David S. Miller authored
    As discovered by Evegniy Polyakov, if we try to sendmsg after
    a connection reset, we can do incredibly stupid things.
    
    The core issue is that inet_sendmsg() tries to autobind the
    socket, but we should never do that for TCP.  Instead we should
    just go straight into TCP's sendmsg() code which will do all
    of the necessary state and pending socket error checks.
    
    TCP's sendpage already directly vectors to tcp_sendpage(), so this
    merely brings sendmsg() in line with that.
