From eccae0f77d3708d591119488f427eca90de7c711 Mon Sep 17 00:00:00 2001 From: Kevin Krakauer Date: Thu, 23 Apr 2020 17:27:24 -0700 Subject: Remove View.First() and View.RemoveFirst() These methods let users eaily break the VectorisedView abstraction, and allowed netstack to slip into pseudo-enforcement of the "all headers are in the first View" invariant. Removing them and replacing with PullUp(n) breaks this reliance and will make it easier to add iptables support and rework network buffer management. The new View.PullUp(n) method is low cost in the common case, when when all the headers fit in the first View.
