    tcp: block connections in both directions

In addition the kernel v3.9 doesn't have a few fixes for tcp:

linux-cr: 2cafdead tcp: don't apply tsoffset if rcv_tsecr is zero v3.11 merged
linux-cr: 85f70a00 tcp: initialize rcv_tstamp for restored sockets v3.11 merged
linux-cr: 81841048 tcp: set timestamps for restored skb-s v3.11 merged

Thanks,
