randconfig qa on x86.git ran into the following new networking related 
problem on latest -git: with the attached .config the testbox comes up 
but cannot establish any TCP connections due to -ENOPROTO in 
sys_connect().

The error comes from this condition in inet_stream_connect():

        /* Connection was closed by RST, timeout, ICMP error
         * or another process disconnected us.
         */
        if (sk->sk_state == TCP_CLOSE)
                goto sock_error;

ICMP pings do work to the machine. Netfilter is on in the .config, maybe 
some new option prevents TCP connections from being established?

CONFIG_SECURITY_NETWORK and CONFIG_SECURITY_SMACK is enabled as well. 
(but that shouldnt throw a no-protocol error)
