From 4962fa10f30d7b563f38467feeae10314b166c77 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Thu, 30 Jul 2015 12:42:46 +0200 Subject: [PATCH] test_bpf: assign type to native eBPF test cases As JITs start to perform optimizations whether to clear A and X on eBPF programs in the prologue, we should actually assign a program type to the native eBPF test cases. It doesn't really matter which program type, as these instructions don't go through the verifier, but it needs to be a type != BPF_PROG_TYPE_UNSPEC. This reflects eBPF programs loaded via bpf(2) system call (!= type unspec) vs. classic BPF to eBPF migrations (== type unspec).
