    [NET]: Make socket creation namespace safe. · 1b8d7ae4
    Eric W. Biederman 提交于
    This patch passes in the namespace a new socket should be created in
    and has the socket code do the appropriate reference counting.  By
    virtue of this all socket create methods are touched.  In addition
    the socket create methods are modified so that they will fail if
    you attempt to create a socket in a non-default network namespace.
    
    Failing if we attempt to create a socket outside of the default
    network namespace ensures that as we incrementally make the network stack
    network namespace aware we will not export functionality that someone
    has not audited and made certain is network namespace safe.
    Allowing us to partially enable network namespaces before all of the
    exotic protocols are supported.
    
    Any protocol layers I have missed will fail to compile because I now
    pass an extra parameter into the socket creation code.
