[PATCH] selftests/seccomp: Abort without user notification support

From: Kees Cook
Date: Wed Jan 16 2019 - 19:35:33 EST


In the face of missing user notification support, the self test needs
to stop executing a test (ASSERT_*) instead of just reporting and
continuing (EXPECT_*). This adjusts the user notification tests to do
that where needed.

Fixes: 6a21cc50f0c7 ("seccomp: add a return code to trap to userspace")
