Hi All I am trying to understand if it is a good idea to have cloned skbs reside on a frag_list?
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 two clones skb1 and skb2 that are clones of the same original skb. Then we try adding skb2 to the frag_list of skb1. Since both skb1 and skb2 share the skb_shared_info structure, skb2's frag_list now points to skb2 creating a loop. This situation also appears to cause a memory leak where skb2 and the actual data are not freed, because calling kfree_skb(skb1) should really free the frag_list, but we can't do that because the skb on the frag list holds the dataref on the same data. Can anyone say that putting clones on the frag_list is a BAD THING (tm) and shouldn't be done? Or is there a way around it?
