From 303def35f64e37bcd5401d202889f5fbc0241179 Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Thu, 17 May 2018 14:16:58 -0700 Subject: bpf: allow sk_msg programs to read sock fields Currently sk_msg programs only have access to the raw data. However, it is often useful when building policies to have the policies specific to the socket endpoint. This allows using the socket tuple as input into filters, etc. This patch adds ctx access to the sock fields.
