TCPMSS packet modification

Hi all,

I’d like to use this extension but I have my doubts on just how often it’s useful.

It would be nice if there were a way to determine this concretely: perhaps it could be reimplemented as a matching filter, and only match on packets that had been changed.

I suspect that most hosts do the right thing, and that most networks correctly pass ICMP Unreachable - Fragmentation Needed, etc. but being able to log packets where this isn’t the case and clamping turns out to be necessary would be a lot more useful.

Anyone have any insight into this?

Thanks,

-Philip
