From d76fc6a7aef6855d0a93a303f6c19726390f70b7 Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Tue, 9 Feb 2016 07:21:33 -0500 Subject: tests: add a test for the different types of socket syscalls We need to test that we are generating filters that can handle both the legacy multiplexed socket syscalls as well as the new direct wired socket syscalls.
