The following changes fix a potential DoS by peers or local users on network interfaces using the sfc driver (and possibly others) with TSO enabled (as it is by default). Please apply patches 1 and 2 to the net tree and your stable update queue. I'm not sure whether patch 3 is really important. Ben. Ben Hutchings (3): net: Allow driver to limit number of GSO segments per skb sfc: Fix maximum number of TSO segments and minimum TX queue size tcp: Apply device TSO segment limit earlier
Series applied, thanks Ben. I think patch #3 does matter, because anything in TCP that cares about the "limit" now must make both tests.
