Hi All
I am trying to understand if it is a good idea to have cloned skbs

I've ran into a situation with SCTP, where it is possible to create
infinite recursion loops by having cloned skbs reside on a frag_list.
We end up in a situation where have tw

The XFRM code base looks like it needs a relatively intrusive change to
support protocols like SCTP correctly. The problem is that security
policies are cached on the socket level, where SCTP not only uses
multiple addresses per association, but multiple associations per socket.
