Ownership of sk_buff

Nov. 24, 2011

      Hi all,

When a protocol like TCP or UDP creates an sk_buff and passes it down
to the layer 3 and layer 2 protocol functions, which module has
ownership of the buffer as it gets passed down?   Is it the
responsibility of the caller, or the callee to free the sk_buff?  Are
there any exceptions?

Thanks,
