From 4f9218aaf8a463f76cac40aa08d859d065f8cc9e Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 16 Oct 2017 16:40:55 -0700 Subject: bpf: move knowledge about post-translation offsets out of verifier Use the fact that verifier ops are now separate from program ops to define a separate set of callbacks for verification of already translated programs. Since we expect the analyzer ops to be defined only for a small subset of all program types initialize their array by hand (don't use linux/bpf_types.h).
