The only case that would break is that where an application relies on the existing (documented as a bug) feature of getting an EMSGSIZE return code in the case of an over-sized packet. Applications that perform their own fragmentation would be unaffected. I think that the benefit of the patch, in moving all fragmentation and reassembly into the kernel, outweigh the very small chance that applications rely on the send of an over-sized packet failing. What is your thinking on taking the patch? Regards Alan
